[0050] The heavy load or a building a structural body may, in particular, such as buildings, bridge, underpass, passage, plinths, as well as a structural part, especially of structures or. Engineering structures, such as a bridge part, be.

[0051] An additional task is, to propose a synchronisation mechanism , by means of which two movable body, in this case the two clamping wedges of the clamping device, can be moved into a defined position relative to one another.

[0052] The synchronisation mechanism is distinguished by a cylinder assembly from, which contains a first and second synchronisation cylinder unit , also referred to as synchronous cylinder,.

[0053] A cylinder arrangement which contains in each case:

-a cylinder, which forms a cylinder chamber;

-a piston rod, which is guided by the cylinder space;

-a piston, which is connected to the piston rod and arranged in the cylinder chamber; and

-a subdivision of the cylinder space into a first and second cylinder chamber through the piston for receiving a hydraulic fluid.

[0054] The first cylinder chamber via a first hydraulic line with the second cylinder chamber is the first synchronisation cylinder unitsynchronisation cylinder unit hydraulically connected the second. The second cylinder chamber of the first via a second hydraulic line to the first cylinder chamber of the second is synchronisation cylinder unitsynchronisation cylinder unit hydraulically connected.

[0055] The piston by preferably both cylinder chambers on the leading piston rod arranged is therefore. D. e., on both sides of the piston surfaces of the piston is a piston rod section formed.

[0056] The piston rod having a first piston rod end preferably with a first contact surface and a second piston rod end with a second contact surface on. The piston rod is guided movably along its longitudinal axis in the synchronous cylinders. The synchronisation cylinder units act with their first piston rod ends or their first contact surfaces on each preferably a movable body, in this case on the clamping wedges.

[0057] Will exerted a force in the direction in which they move on the piston rod of the one now synchronisation cylinder unit , e.g. by a clamping wedge, so these shifts in the direction of the action of the force. Accordingly is coupled to the piston rod in the form of synchronous cylinders also displaces the piston. Through the displacement of the piston increases the volume in the one cylinder chamber, while the volume in the other cylinder chamber ([...]) is the same dimension reduced in size. The total volume of the first and second cylinder chamber changes according to not.

[0058] in all this hydraulic fluid from the cylinder chamber is decreased, which is, e.g., from the first cylinder chamber, displaced. This [...] flows into the hydraulic fluid, to and from the second cylinder chamber of the other synchronisation cylinder unit. Hydraulic fluid flows in those cylinder chamber On the other hand, which is enlarged, i.e. in the second cylinder chamber. This [...] flows from the hydraulic fluid, i.e. the first cylinder chamber, the other to synchronisation cylinder unit.

[0059] By the forced displacement of the hydraulic fluid between the two synchronisation cylinder unitssynchronisation cylinder units synchronously move the piston rods of the two with each other. Accordingly support two, each having a piston rod which is operatively connected, movable body, such as clamping wedges, synchronously moved together.

[0060] According to a preferred refinement of the invention is at least one piston rod, preferably both piston rods in operative connection with a spring element, which exerts a restoring force on the piston rod in the direction of the piston rod end, which is in operative connection with the movable body. In the present case the restoring force acts against the displacement direction. The spring member effected, in the event that the piston rod to an initial position in the direction of the action of force in the longitudinal direction thereof the movable bodies, or. Clamping wedges is moved back.

[0061] The spring member is preferably a mechanical spring, in particular a helical spring. The spring can be constructed as a tension or compression spring, depending on the arrangement.

[0062] Thanks to the described two body can synchronisation mechanism , as clamping wedges, in the direction of movement of the piston rods are moved to a defined position relative to each other, irrespective of, which force on the individual piston rods, e.g. by the these conflicting body or. Clamping wedges, are exerted. This defined position can be for example thereby that the two bodies in the direction of movement of the piston rods are located at the same height. Wise Men same shape on the two bodies, as in the slips may be the case, so this position can correspond to an axisymmetric arrangement the body, wherein the axis of symmetry extends parallel to the direction of movement of the piston rods.

[0063] According to a preferred refinement of the invention contains a clamping thrust devicesynchronisation mechanism the according to the invention, in particular a synchronisation mechanism the same manner as described above. This ensures that the clamping wedges for drawing up the clamps into the guide depression between the guide sides displacement direction are moved into a mutually defined position along the.

[0064] The synchronisation mechanismsynchronisation cylinder units of the above-described via the cylinder housing are preferably mounted on the clamping head. A first piston of the first with the first clamping wedge synchronisation cylinder unit is above the piston rod and the piston of the second piston rod is in mechanical communication with the second clamping wedge synchronisation cylinder unit is above the. The displacement direction are disposed parallel to the piston rods.

[0065] According to the slips are arranged in front of the the piston rods invention variantdisplacement direction considered first. displacement directioninvention variant the piston rods are viewed in behind the second According to the slips arranged.

[0066] The synchronisation mechanism is in connection with the operation of the described processes may subsequently.

[0067] Succeeds the method according to the invention is described for moving heavy loads with the above-described device and for transferring the clamping wedges synchronisation mechanism to a defined position relative to each other by means of a described above.

[0068] The according to the invention is distinguished by the following steps of method:

-Introducing a clamping motion of the clamping head displacement direction by the thrust member parallel to the;

-A frictional clamping connection between the clamping device and the holding element in a positive-locking and establishing/or;

-Introducing a translating movement displacement directiondisplacement direction and shifting the heavy load by the thrust member in in.

[0069] According to invention variant is the clamping movement along the first displacement direction. displacement directioninvention variant the clamping movement is counter to the second According to the.

[0070] The clamping connection between the clamping device and the holding element is preferably produced by a displacement of the slips are in the guide depression parallel to the displacement direction.

[0071] The Mass of the thrust motion per combustion cycle depends on the maximum operational path of the thrust member from. The thrust member a cylinder-Arrangement Is, so this distance depends on the maximum stroke of the piston (the piston is moving out of the cylinder) as from. Has now the thrust member or its maximum operational path. Piston stroke achieved, so the following method steps are carried out:

-The positive-locking and releasing or frictional engagement by a release action of the clamping head displacement movementdisplacement direction by the thrust member after completion of the parallel to the;

-Taking an adjusting movement of the clamping head by the thrust member for release action equioriented, wherein the clamping head slides along of the holding element.

[0072] displacement directioninvention variant is the release action against the the first According to. displacement directioninvention variant the release action is in the second According to.

[0073] The invention variant[...] adjusting movement corresponds to a retraction preferably according to the first or. The clamping head moving back.

[0074] With the adjusting movement of the clamping head is again brought into a displacement clockdisplacement position for a next.

[0075] the thrust member a cylinder-Arrangement Is, so is effected by the rearward movement of the piston in the opposite direction the [...] adjusting movement (return stroke, return travel of the piston in the cylinder).

[0076] the thrust member or the piston has reached the cylinder-Arrangement Has its initial position, so the displacement clock is complete. By re-initiating a clamping motion of the clamping head by the thrust member after completion of the adjustment movement parallel to the can a new displacement directiondisplacement clock be initiated. The mentioned steps are carried out in turn it.

[0077] The number of [...] to be performed. displacement clockdisplacement clocks depends on the dimension of the displacement per the measurement of the overall displacement of the heavy load and from.

[0078] [...]displacement movement is solved after the completion of the adjusting movement of the clamping head during the the clamping joint between the retaining member and the slips often not synchronously, i.e. non-uniformly. This has the consequence that the clamping wedges displacement direction after completion of the adjustment movement along the no longer at the same height, but are shifted relative to one another disposed.

[0079] This the clamping wedges are displacement direction arranged offset from one another along the upon re-producing a clamp connection. This offset exceeds a certain measure, so it may happen that the support element on the one hand no longer had the clamping wedge but via a guide element, such as guide cam, the clamping head is clamped. This can lead to considerable malfunctions, with the holding element, for example, keyed by the clamping head.

[0080] The clamping thrust device therefore sees a synchromesh device according to the invention before as described above, which ensures that the clamping wedges during the re-clamping connection with Creating displacement directiondisplacement of the clamping head on the same height relative to each other are guided along the.

[0081] This is done, by during the adjusting movement of the clamping head in or counter to the relative to the other clamping wedge with a leading stop edge displacement direction advanced clamping wedge in abutment with the respective face of the piston rod passes.

[0082] In the case of further clamping movement of the clamping head for the purpose of creating the clamping connection, the clamping wedges by the synchronously movable piston rods are aligned along in the direction of the clamping movement again at the same height. In all this a certain transverse displacement will take place instead of the clamping head.

[0083] The according to the invention is a passively operated system synchroniser means, which must be regulated or not actively controlled. Therefore the operation is simple and with less expense connected such a synchroniser means.

[0085] in Figures equal parts are provided with identical reference symbols in principle. The invention article and have no restrictive effect there are, for example, for the embodiments described.

[0086] The clamping thrust device 2 according to Fig. 1 to 4 contains a first (first invention variant) displacement direction S arranged at a distance from the cylinder, a second supporting body and in 6, 7. The two supporting body 6, 7 are arranged one behind the other in displacement direction S. The supporting body 6, 7 comprise a hydraulic cylinder, via which the heavy load lifted and 27 may be supported.

[0087] 6 is a clamping head displacement direction S leading first support body on the 4 arranged in. The clamping head 15 through a slide bearing 4 and the first supporting body parallel to the 6 are slidably supported on a supporting structure 5 displacement direction S. The supporting body 4 and is guided on this 6 is connected with the clamping head.

[0088] The supporting structure 5 contains two base plates 17a, 17b, which rest on a foundation, for example, 30, 31 (see Fig. 3). The two base plates 17a, 17b are rigidly connected to each other.

[0089] The sliding bearing comprises a sliding plate 15 of PTFE, which is disposed between the first support body 6 and a first base plate 17a.

[0090] Laterally of the base plates 17a, 17b are displacement direction S 18 arranged strengthening ribs extending parallel to the. The Bracing the supporting structure 18 reinforcing ribs 18 must serve but not compellingly be provided 5. The reinforcing ribs. Also the base plate can also be designed as a single part.

[0091] The clamping head 4 is connected in an articulated manner to the thrust member through a first connection 3. The thrust member is in the form of a hydraulic cylinder 3. The displacement direction S 3 is opposed to the thrust member 7 in the direction of the second support body 5 connected in an articulated manner to the supporting structure and guided via a second link. The operating path of said thrust member extends between the first and second supporting body 3 extends 6, 7.

[0092] The second supporting body 7 is supported on the second base plate 5 17b the supporting structure. The second supporting body 5 or respectively of the second base plate 7 is fixedly connected with the supporting structure, 17b.

[0093] The clamping head 8 with a guide depression 4 contains a basic body 9, which laterally from a first and second guide wall 11a, 11b and is limited against guidance ground below through a 10. The guidance ground forms from a sliding surface 36.

[0094] The guide walls 11a, 11b Close displacement direction S parallel straight lines with a for an angle a, wherein the guide depression narrows displacement direction S 9 against the funnel-like manner.

[0095] 9 is a sliding plate 10 of the guide depression 15 of polytetrafluoroethylene guidance ground In (PTFE) embedded, which serves as a sliding bearing.

[0096] The clamping head 4 contains further two clamping wedges 12, 13, which in each case on one of the guide walls 9 in the guide depression 11a, 11b are arranged. The clamping wedges 12, 13 are parallel to the 8 with respect to the base body as well as transversely to the movably disposed displacement direction S displacement direction S.

[0097] The clamping wedges 12, 13 form a contact surface with a first contact wall respectively facing guide wall 14a to the this 11a, 11b of the clamping head from 4.

[0098] also form the clamping wedges 12, 13 in each case with a second contact wall 37 for holding member 14b from a clamping face 26. The clamping wedges Where 12, 13 with its first contact wall 14a the guide walls 11a, 11b of the guide depression at 9, so the first contact wall closes displacement direction S parallel straight lines with a for an angle a. The displacement direction S 14b extends parallel to the second contact wall.

[0099] 9 8 has further at the beginning of the guide depression The base body on both sides in each case a guide cam 16a, 16b from. These are used as a guide for the holding element 26, when the clamping connection is completely dissolved.

[0100] The holding element 26, which is connected fixedly with the to be displaced heavy load, than Wide Flats formed. The Wide Flats displacement direction S 26 runs parallel to the.

[0101] The Wide Flats 26 is guided and lies with its sliding surface 9 in the guide depression 38 on the slide plate 10 or respectively of the recessed therein guidance ground 15 on.

[0102] the piston of the thrust member 3 is now extended displacement movement of performing re- displacement direction S in from the cylinder. This the clamping head 6 on the supporting structure together with the first supporting body 4 is 5 in the clamping direction K, which corresponds to the displacement direction S, shifted. The base body 4 slides during this operation with the guide surfaces 8 of the clamping head 11a, 11b along the first contact walls 14a of the clamping wedges 12, 13.

[0103] The clamping wedges 12, 13 are in a relative movement during that operation in the guide depression displacement direction S 9 moved counter to the. By the wedge-shaped configuration of the clamping wedges 12, 13 will take place in continuous displacement movement to wedge the clamping wedges 12, 13 between the guide wall 11a, 11b and the support member instead of 26. This leads to the result that the clamping wedges 12.13 with the guide walls 11a, 11b of the main body 39 of the holding element 8 and 26 come into contact with the clamping surfaces between the retaining member 26 and the clamping head and on the clamping wedges 4 12.13 Establishing a frictionally engaged connection.

[0104] Once the frictionally engaged connection is made is offset by the thrust member 26 with continuing displacement movementdisplacement direction S displaced in movement and in 3 the heavy load.

[0105] The by the working stroke of the piston of the thrust member is 3 predetermined displacement rate per displacement clock. After reaching the maximum working stroke the piston is again retracted. The 4 is solved with the return stroke of the piston in the release direction L clamping head by the retaining element 26 and in the direction of adjustment V into a displacement position withdrawn. In all this releases the clamping connection between the clamping head and the holding element 4 in the same direction as and the opposite direction of adjustment are [...]displacement direction S. 26.

[0106] Once the piston is withdrawn into the displacement position , with the extension of the piston of the thrust member can be initiated a new displacement clock 3. This begins again with the clamping of the clamping head 12 on the clamping wedges 26 on the holding element 4, 4 of the clamping head 13 by the displacement movementdisplacement direction S in.

[0107] displacement direction S front end of the base body 8 is in a on the 20 (see Fig. 4) synchronisation arrangement mounted. The synchronisation arrangementsynchronisation cylinder unit 21.22 20 comprises a first and second, which each have a clamping wedge 12, 13 are assigned before the slips displacement direction S viewed in and 12, 13 are arranged. The synchronisation cylinder unitsdisplacement direction S 21.22 are aligned parallel to the.

[0108] Through the cylinder 23 is a piston rod guided synchronisation cylinder units 32.33 of 21.22, which forms a for clamping wedge 12, 13 facing end face. The end face constitutes an abutment surface for the clamping wedges 12, 13 constitute.

[0109] Within of the cylinder 32, 33 is a piston 34 arranged on the piston rod 23. The piston divided into a first and second cylinder chamber the cylinder space 24a, 24 b. By displacement of the piston 34 within the cylinder space is increased the volume of the a cylinder chamber, while the volume of the other cylinder chamber is the same (see 7 and 8 Fig.) mass decreased.

[0110] The cylinder chambers 24a, 24b are with a hydraulic fluid, e.g. a hydraulic oil, filled. The magnification or. Reduction of the cylinder chambers 24a, 24a 24b leads to a supply of hydraulic fluids into the cylinder chamber, or to a displacement of hydraulic fluid from the cylinder chamber 24 b.

[0111] The cylinder chambers 24a, 24b of the first 21 are now by means of hydraulic lines synchronisation cylinder unit 25a, 25b-derived from the cross with the cylinder chambers 24a, 24b of the second 22 connected synchronisation cylinder unit. D. is to say, the first cylinder chamber 21 via a first hydraulic line 24a of the first with the second cylinder chamber 25a is synchronisation cylinder unit 24b of the second 22 hydraulically connected synchronisation cylinder unit. The second cylinder chamber 21 via a second hydraulic line 25b is synchronisation cylinder unit 24b of the first with the first cylinder chamber 24a of the second 22 hydraulically connected synchronisation cylinder unit.

[0112] The above described arrangement ensures that the two piston rods always move synchronously with each other axially. Will exerted on the a piston rod, for example, an axial force, so moves the piston rod in the direction of the acting axial force. In all this also moves piston 34 in the cylinder at the piston rod 23 coupled, what leads to a volume change in the two cylinder chambers 24a, 24b. For of those cylinder chamber, the volume of which, reduced in size, the displaced hydraulic fluid through the hydraulic line is passed into the correspondingly synchronisation cylinder unit[...] the other. Plus the corresponding Mass [...] The volumes of is.

[0113] This volume enlargement has been accompanied by a displacement of the piston in the cylinder chamber and thus the piston rod. Similarly in those cylinder chamber is enlarged, the volume of which, , the corresponding quantity hydraulic fluid introduced via the hydraulic line. This hydraulic fluid escapes from the corresponding synchronisation cylinder unit[...] the other. The described flow of hydraulic fluid between the cylinder chambers of the two synchronisation cylinder units result is that the piston rod 23 a for actively moving piston rod 23 of the other synchronous synchronisation cylinder unit , axial movement is taking place.

[0114] The synchronisation arrangement 20 contains further includes spring means 35, which exerts displacement direction S leasing clamping wedge in a against the 12, 13 restoring force acting on the piston rod 23. The spring means comprises a tension spring 23 extending parallel to the piston rod 35 in the present implementation, with its first end via a connecting element to the piston rod 8 is connected to the base body 23 and with its second end (see Fig. 4).

[0115] The tension spring on the piston rod 23 from a pulling force against the displacement direction S shall exercise. The tension spring ensures that the piston rod 23 with its to the clamping wedge 12, 13 facing end face is brought into abutment with a stop face of the clamping wedge, 12.13.

[0116] Will dissolved now upon release of the clamping connection following a 12 displacement clock the clamping wedges, 13 is unevenly Move displacement direction S relative to one another so these parallel to the can, so that their stop faces no longer are at the same height. When displacement movementdisplacement clock the clamping wedges are aligned for the subsequent introduction of the 12, 13 therefore permit movement of the clamping head 4 before formation of the clamping connection in cooperation with the piston rods by the 23 of the synchronisation arrangement 20 again at the same height.

[0117] This a axisymmetric arrangement is achieved of the symmetrically shaped clamping wedges 12, 13 in the clamping position.

[0118] The than Wide Flats formed on the underside of a retaining element 26 can, for example, in a building 28 27 displacement direction S longitudinal retainer can be mounted. The retaining studs 28 on the via 27 is therefore The construction works (see Fig. 6) 2 supported clamping thrust device.

[0119] The Fig. 5a to 5c show a construction by means of a device according to the invention the displacement 27 27 represents, for example, constitute a passage 1st The construction works.

[0120] The device 1 comprises several clamping thrust devices 2, which are arranged in series one behind the other along the displacement course. Also the device contains a plurality of additional supporting body 29 in the form of hydraulic cylinders, which also are arranged in series with the one behind the other along the displacement courseclamping thrust devices 2. The additional support body 29 are displacement direction S in before, after and 2 arranged between the clamping thrust devices.

[0121] The present device 1 provides for two spaced rows of support bodies clamping thrust devicesdisplacement direction S 29 and from each other across the in the arrangement described above, before 2.

[0122] respectively along two parallel side walls 27 forms a longitudinal The construction works 28 from retaining cams. On the bottom side 28 is a respective retaining element in the form of a the holding cam wide flat steel mounted 26. The construction works via the two retaining cams 27 lies over the mounted thereon 28 or 26 Wide Flats, the two rows of support bodies clamping thrust devices 29 and 2 on.

[0123] The additional support body 29 and 31 are on a foundation 2 on foundation elements 30 or the supported clamping thrust devices. For example, in a foundation is composed of several successively arranged mobile foundation elements displacement direction S are formed 31, which can be removed again after the completion of the displacement.

[0124] Zur displacement of the building below the two longitudinal retaining protuberances 27 is the same over the raised 28 29 and on the supporting body arranged at a distance from one another in each case also under the two retaining cams 29 are each arranged in series with the support bodies 28 clamping thrust devices 2. In a subsequent step the structure is displaced cyclically displacement direction S clamping thrust device in 27 by means of the 2.

[0125] 27 slides over the supporting bodies 29 and the construction in all this time the 2 clamping thrust device. The support body 29 in the form of plate elements of PTFE on their supporting surfaces sliding members contain thereto. The support body 29, as well as the 30 during the displacement at a fixed position on the foundation 2 remain clamping thrust device.

[0126] Needless retainer canclamping thrust devices 2 arranged one behind the other can be also more below a 28. These can operate e.g. in the [...] push-pull manner.

[0127] During the displacement of the building 29 27 27 displacement direction S heretofore Building be continuously supporting body or in. clamping thrust devices 29 or 2 in continuation of the two rows of supporting bodies. clamping thrust devices 2 placed in position. The construction works during its displacement on the slides 27 and 29 arranged in front thereof, as well as the supporting function 2. This Apply clamping thrust devices the supporting body displacement function.

[0128] The displacement direction S behind the changing Building 27 released in 29 and 27 again before Building clamping thrust devices 2 in this case can support body in the displacement course are placed in position.

[0129] 9 and 10 show a clamping thrust device 102 according to a second Fig. The invention variant. invention variantinvention variant is in principle a reversal of the first second The constitute. Therefore the second invention variantclamping thrust deviceinvention variant contains substantially the same components as the other, however, in accordance with the first arrangement.

[0130] The clamping thrust devicedisplacement direction S 102 contains a first and a second supporting body arranged at a distance from this in 106, 107. The two supporting bodies 106, 107 are displacement direction S arranged one behind the other in. The support body 106, 107 comprise a hydraulic cylinder, may be supported over which the heavy load lifted and 127.

[0131] displacement direction S trailing first supporting body 6 is a clamping head Underneath the 104 arranged in. The 104 106 115 and the first supporting body via a sliding bearing are clamping head with respect to a supporting structure 105 displacement direction S slidably disposed parallel to the. The support body 104 106 is connected to the clamping head.

[0132] The supporting structure contains a two-part base plate 105 117, 127 which is connected with the heavy load.

[0133] The sliding bearing comprises a sliding plate made of PTFE is arranged between the first support body 106 and the base plate 117.

[0134] The clamping head in an articulated manner to the thrust member 104 is connected through a first connection 103. The thrust member is in the form of a hydraulic cylinder 103. The thrust member 107 103 is guided towards and in the direction of the second supporting body displacement direction S in via a second link 105 connected in an articulated manner to the supporting structure. The operational path of the thrust member 103 extends between the first and second supporting bodies 106, 107.

[0135] The second supporting body 105 107 117 fixedly connected with the supporting structure is over the base plate.

[0136] The clamping head 104, which is constructed analogous to the clamping head 4 after Fig., a base body with a guide depression 108 contains, which laterally from a first and second guide wall and against guidance ground Few will bottom by a.

[0137] The Close displacement direction S an angle a with a straight line parallel to the guide walls, wherein the guide depression narrows in funnel-like manner displacement direction S.

[0138] (PTFE) is a sliding plate made of polytetrafluoroethylene guidance ground the guide depression in the embedded, which serves as a sliding bearing.

[0139] The clamping head 104 contains further comprises two clamping wedges 112, 113, which are arranged in each case on one of the guide walls in the guide depression. The Chocks 112, 113 are displacement direction S displacement direction 108 with respect to the base body movably disposed parallel to the wall and transversely to S.

[0140] The Chocks 112, 113 to form a contact surface with a first contact wall 104 facing guide wall of the clamping head from each of these. Also form the clamping wedges 112, 113 each having a second contact wall 126 from a clamping face for retaining element. The clamping wedges Where 112, 113 with its first contact wall the guide walls of the guide depression on, so the first contact wall closes displacement direction S parallel straight lines with a for an angle a. The displacement direction S runs parallel to the second contact wall.

[0141] The base body on both sides in each case at the beginning of the guide depression 108 further comprises a guide cam from. These are used as a guide for the holding element 126, when the clamping connection is completely dissolved.

[0142] The holding element 126 is displacement at least during the with a, or during a connected fixedly connected displacement clock fixed structure. The holding element 126 is formed here as Wide Flats. The Wide Flats displacement direction S 126 runs parallel to the.

[0143] The Wide Flats guidance ground lies or in the guide depression 126 is felt and the skid plate to the recessed therein.

[0144] displacement movement is now the piston of the thrust member 103 of performing re-extended from the cylinder. This the clamping head is displaced together with the first supporting body 104 106 while executing a clamping movement counter to the clamping direction K along of the holding element 126 displacement direction S in. The first support body slides relative to the supporting structure in the clamping direction K 106.

[0145] The base body 104 of the clamping head 108 slides along the first contact walls of the clamping wedges during that operation with the guide surfaces 112, 113.

[0146] The Chocks 112, 113 are in a relative movement in the guide depression moved during that operation. By the wedge-shaped configuration of the clamping wedges 112, 113 will take place in continuous clamping movement to wedge the clamping wedges 112, 113 between the guide wall and the 126 instead of [...]. This leads to the result that on the clamping wedges [...] 112.113 104 126 and the clamping head is a frictionally engaged connection between the prepared.

[0147] Once the frictionally engaged connection is made, by the thrust member 103 is introduced a displacement movement , with which the heavy load and set in motion in Moving displacement direction S 126.

[0148] The displacement movement at the clamped clamping head 103 104 from principle by which the thrust member, while the thrust member 127 103 105 together with the heavy load at the same time the resting structure displacement direction S moved in.

[0149] After reaching the maximum working stroke the piston of the thrust member 103 is again withdrawn. In all this the thrust member 103 shall exercise in the releasing direction L, which corresponds to the displacement direction S, 104 from a release at the clamping head, whereby the clamping head 104 again from the holding element 126 is solved. After releasing the clamping head 104 is guided in a for release action equioriented adjusting movement V into a displacement position this.

[0150] As soon as the piston is withdrawn and the clamping head to the initial position has reached its displacement position 104, with the extension of the piston of the thrust member 103 can be introduced a new displacement clock. This begins again with the clamping of the clamping head 126 on the clamping wedges 104 on the holding element 112, 113.

[0151] displacement direction S 108 is installed on the rear of the body 20 in a mounted synchronisation arrangement. Regarding structure and operatively 4 and the accompanying description of the synchronisation arrangement is cited on Fig..

[0152] The invention variantinvention variant further analogous to the first device according to the second can, for example contain displacement direction S arranged one behind the other in supporting body. These are preferably integral with the to be displaced are driven to move accordingly with the heavy load and heavy load.

[0153] The device according to the invention has the advantage that these extremely space saving is. For with the exception of the foundation, on which the structure is displaced, in front of, behind and laterally from the Building no significant, space receivable installations necessary. The clamping thrust devices the essential components of the device are arranged as supporting body and below of the structure, which is supported on this. The individual components the inventive device, as being independent of each other and also comparatively small and handy clamping thrust devices supporting body and. This allows a modular construction of the device as a function of the type and size of the building.

[0154] in contrast to conventional solutions clamping technology via a by means of the construction Since holding element is shifted to the building, no long rail guides are further along the entire displacement course necessary.
