Einrichtung zur distanzierten befestigung von wärmedämmplatten an wänden oder decken

The invention refers to a mechanism for the reserved attachment of Wärmedämmplatten at walls or covers with a central, a longitudinal drilling for the admission a head possessing fixing bolt exhibiting shank with at least a volume screw surface-like rotating this shank and at outside face of the shank the beginning and attack of a turning tool the serving recess lying coaxially with the longitudinal drilling is angeformt. Such a mechanism is from the RK 404,271 B well-known. The fixing bolt serving for the definition of this mechanism has a head and a thread shank. If this mechanism is intended used, then the head of this fixing bolt of at the front side lying recess of the Schaf'tes is completely taken up. The stirnseJtige end of the central, the circulating volume of exhibiting shank of the mechanism is carried back opposite the outside limiting wall of the Dämmplatte. The opening remained thereby in the Dämmplatte can be locked. There is now frequently the desire to attach in this way the thermal insulated external wall a Fassadenverkleidung. For the solution of this task it is suggested according to invention that the fixing bolt exhibits two shanks, whereby to both sides of the head one shank each is intended and carries if necessary both sharp threads. This second shank is so for a long time limited that it auskragt in relation to the exterior of the Wärmedämmplatte, and at this auskragenden shank now fittings can be specified, which serve for the attachment of front lining elements. If the shank pre-assembled-rising up opposite the Wärmedämmplatte, which to round or can have polygonal cross section, possesses an essentially smooth surface, then to it Klernmbriden are fastened. If this auskragende Schaftteit is equipped with a thread, preferably with a metric thread, then nuts can be untwisted, which serve for the mounting plate of fitting, at which the front lining elements then to be fastened are. For the illustration of the invention this is more near described on the basis the design. Show: Fig. 1 the mechanism in side view; Fig. 2 in opinion line of sight arrow C; Fig. 3 a side view of the mechanism such as Fig. 1, however partially broken; Fig. 4 the fixing bolt; Fig. 5 the fixing bolt as from Fig. 4, however with screwed on threaded sleeve; Fig. 6 a tool and a Fig. 7 its opinion - line of sight arrow A in Fig. 6; Fig. 8 the mechanism intended assigned. In Fig. 1 illustrated mechanism, which is manufactured from a suitable plastic appropriately einstückig, possesses a central shank 1, that by a longitudinal drilling 2 is interspersed for the admission of a fixing bolt 3 (Fig. 4, 8), whereby the outside diameter of the fixing bolt corresponds for instance to the diameter of the longitudinal drilling 2, smaller than these it is, so that the fixing bolt is put throughable 3 by the longitudinal drilling 2 and exhibits in this longitudinal drilling 2 a small play. At this central shank 1 are externallaterally a screw surface-like rotating, here split volume 4 intended. The average width B of the same referred to the length of the screw surface-like rotating volume 4 is more largely as the outside diameters D of the central shank 1. the relationship of the middle outside diameter AD of the screw surface-like rotating volume 4 to the outside diameter D of the central shank 1 amounts to with the remark example illustrated here about 3,5: 1. The upward gradient of the screw surface-like rotating volume amount to for instance mm. At least the part of the screw surface-like rotating volume 4, which steps when assembling with the Wärmedämmplatte 5 forward-moving into effect connection, exhibits with increasing upward gradient increasing width and shows thus a spiral process of the delimitation edge. To outside face 13 of the shank 1 is intended the beginning and the attack of a turning tool serving, here polygonal recess 6. The Einlaufkante of the screw surface-like rotating volume 4 and its edge edge is out-arranged also appropriately over its length cut-like. The mechanism shown here can be manufactured also from a metallic material. The RKs 4O7 539 B managing indicated dimensions and dimension conditions refer to the remark example shown in the design. These dimensions and dimension conditions are to be adapted to the materials, from which the Wärmedämmplatte 5 is manufactured. These dimensions can vary from there both upward as well as downward. The fixing bolt 3 (Fig. 4) possesses a first thread shank 7. this thread shank is out-arranged for the admission of a handels0blichen Kunststoffd0bels. The second shank 9 carries here a metric thread 10. between the two peeled 7 and 9 is angeformt by a widening a head 11, for its first thread shank 7 turned page 12 essentially corresponding to the reason 14 (Fig. 3) the recess 6 is trained. The tons of diameters of the head 11 is larger than the diameter of the drilling 2 in the shank 1 of the mechanism. At the front side a transverse groove 15 is formed out, here can a turning tool be set at the second shank 9. In place of such a transverse groove 15 also a multi-Kant could be angeformt here. In place of the metdschen thread 10 at the second shank 9 this shank could be trained also with smooth surface and circular cross section, or however it could exhibit a polygonal cross section. This fixing bolt 3 could be described also in such a way that by it is stated that in its center section a widening is, whose diameter is larger than the diameter of the longitudinal drilling 2 of the shank 1. Fig. the same fixing bolt shows 5 as Fig. 4, however is here on the thread 10 of the second shank 9 a Gewindeh01se “[6 screwed on, which carries a thread 17 also at its exterior. The length of this threaded sleeve 16 corresponds for instance the Lounge of the second shank 9. At a building wall 18 externallaterally a thermal insulation is to be attached. Into the here anzubdngende Wärmedämmplatte 5 the mechanism becomes after the Fig. 1 to 3 screwed in, so far that their a front end 19 manages gegen0ber of the Begrenzungsfiäche 20 of the Dämmplatte 5 something, then is aligned the Dämmplatte 5, regarding its horizontal situation. By means of a suitable tool with a drill, which is introduced now to the longitudinal drilling 2 of the mechanism, into the building wall 18 a drilling is bored for the admission of a peg 8. Subsequently, to the first shank 7 of the fixing bolt 3 a plastic peg is attached and these together with the fixing bolt 3 into and by the longitudinal drilling 2 of the mechanism are put through and the peg 8 is put into the drilling prepared for its admission in the building wall 18. At the transverse groove 15 of the fixing bolt 3 now a turning tool is used and the fixing bolt so far into the peg 8 is pivoted, until its head 11 at the reason of 14 of the recess 6 accumulates. In order to align now the Dämmplatte 5 regarding their distance B opposite the building wall 18, now a tool 25 is used, that into the Fig. 6 and 7 shown is and according to kind of a spark plug key is trained. This tools 25 consist 21 with a finallateral cross hole 22 of a pipe for passing a staff through. The other end of the pipe 21 is to one multi-hits a corner 23 expand, whose outer contour corresponds to the cross section outline of the recess 6 and which is so limited that it can be put into this recess 6. This tools 25 are attached now to the auskragenden shank 9 of the fixing bolt, so that multi-hit a corner 23 into the recess 6 rises up. By tricks of the tool 25, which connected by its Mehre¢k is 23 with the mechanism formschl0ssig, now the mechanism can be rotated, which is fixed regarding their situation opposite the building wall 18, whereby the Dämmplatte 5 opposite the building wall 18 is adjusted and thereby depending upon direction of rotation the distance B becomes larger or makes smaller. Subsequently, the tool is again taken off. If the Dämmplatte 5 is aligned in this way, then on the thread 10 of the second, opposite the Dämmplatte 5 auskragenden shank 9 a nut with collar 24 with a far so auskragenden federation is screwed on. In place of such a nut with collar a conventional mother with an accordingly large shim can be planned. Onto this auskragenden part of the shank 9 now still two further Bundmuttem 26 and 27 are screwed, between which a a thigh of the here u-shaped piece of profile of 28 is strutted. This piece of profile of 28 serves now as fitting, at which front parts can be specified. If the auskragende shank 9 is smoothly, thus trained without thread 10, then fittings can be fixed to the RK 407,539 B attachment by front parts for example by Klemmbriden. In order to find with a size of the fixing bolt 3 the sufficiency, a threaded sleeve 16 intended with an external thread 17 is for the shank 9 (Fig. 5). If thus the auskragende shank 9 should prove because of the strength of the Dämmplatte 5 as too short, the threaded sleeve 16 can be so far turned off that it auskragt in relation to the front side end of this shank 9. At this threaded sleeve 16 the flange screws are then untwisted, which serve for the mounting plate of that fitting, to which the front part to be fastened are. Owing to invention in accordance with lBen arrangement the fixing bolt 3 this can fulfill vorliegendenfalls to two functions. On the one hand it serves the mechanism at the exterior of the building wall which can be dammed for the definition, on the other hand one it is suitable for taking up fitting to which front lining elements can be specified. These fittings can be very differently arranged. They must possess only one recess, by which the auskragende part of the shank is pass throughable 9. Owing to the round nut 24 with the federation unloading far the auskragende section of the shank 9 sufficiently opposite the Dämmplatte 5 is supported, so that this auskragende section of the shank is relatively highly loadable 9.
