PIPE AND/OR TUBING FORM STUCCO AS WELL AS PROCEDURE AND DEVICE FOR ITS PRODUCTION

The invention concerns a pipe and/or a fitting, an in particular channel, Drainageund/or thick matter pipe, from a vividly ductile and mass tied thereafter confirmed and/or, preferably a faserhälrigen or vliesbzw. cast stone-similar mass, for example Faserbzw. Asbestos cement. The invention concerns further a procedure and a device for the production of such a pipe and/or fitting. By Kanu] -, Drainageund/or thick matter pipes is required that on the one hand with small throughput quantity as large a flow height as possible is given, so that the dirt bodies and/or Veruureinigungen are as completely as possible carried forward by the current, and that on the other hand however sufficient free cross section for extremely large throughput quantities, for example with flood, is present Gewitterregen etc. Due to these requirements the well-known Kanu] pipes with egg-shaped cross section were developed, which are moved in such a manner that the pointed pole of the egg points downward. This well-known KanaXrohre is made today almost exclusively by pouring, mostly of cement concrete mixtures, since the egg-shaped cross section with the well-known asbestos cement tube machines is not producible. The Gieߣormvorgang is extremely arbeitsanfwendig hiebei. In order to receive in addition the desired firmness, relatively large wall thicknesses are necessary, which leads again to that these well-known sewer pipes exhibit large weight. The well-known firmness advantage and with it coupled the Gewichtsvortefl of Faserzement-bzw. Could not be transferred to asbestos cement tubes with circular cross section opposite concrete pipes to sewer pipes with egg-shaped cross section so far, since for the production of shaped parts made of asbestos cement a material compression is necessary in the form of application of pressure. During the production of pipes with circular cross section made of fibrated concrete and/or asbestos cement the necessary compression printing is expenditure-practiced thereby on the workpiece that the pipe is turned during the winding procedure between two and/or three rollers. A roller, preferably the upper, evades so-called Equipage with increasing wall thickness upward, whereby the necessary compression printing is kept constant, preferably even reduced. If one wanted to turn now a pipe with egg-shaped cross section between two printingburdening rollers, then at least one roller would have a reciprocating movement would constantly drive out. An in such a manner reciprocating Wu] CPU with pressure to subject evenly or even the application of pressure after a certain dependence from the winding time to reduce, is to be realized with the present state of the art not rationally. In addition large Massenbeschleunigungskräfre arises according to, which is to be controlled with difficulty. Task of the invention is it to avoid and pipes and/or fittings create these disadvantages, which correspond to the initially mentioned requirements, however with smaller work expended as the well-known Eipro£il pipes on mößichst rational way to be manufactured can and a higher firmness than the well-known Eiprofll pipes possess. This is reached in accordance with the invention with a pipe and/or a fitting of the kind initially specified by that the cross section of the pipe and/or fitting exhibits essentially the form of a Reuleaux triangle, in particular a Gleichdicks. By a Reuleaux triangle an equilateral triangle is understood, whose sides circular arcs curved through outward are replaced, whereby the radius of these circular arcs is equal to the side length of the equilateral triangle. In such a way trained pipes according to invention correspond - if them with a point of the Reuleaux triangle and/or the rounding of edge of the Gleichdicks downward pointing move will-completely the requirements initially specified regarding as large a velocity of flow as possible with small flow quantities and sufficient free cross section flir extreme throughput quantities. A Reuleaux triangle and/or equalthickly are between two parallel thighs of a measuring instrument measured in each position equivalent thick. Thus according to this principle manufactured pipes according to invention can be manufactured in substantially simpler way than a conventional EiprotBrohr, similarly the well-known fibrated concrete pipes, by a continuous winding procedure. In Ausgestakung of the invention it is intended that also the outside cross section of the pipe and/or. Fitting essentially the form of a Reuleaux triangle and/or a Gleichdicks exhibits, whereby the internal and outside cross section forming Reuleaux triangles and/or Gleichdicks are arranged coaxially and sideparallel, so that the wall thickness of the pipe and/or fitting is essentially equally large in all places. For the production of the pipe and/or fitting according to invention the invention suggests a procedure, with which a Materiu] to course from vividly ductile material around a core is rolled up, and which thereby marked is that during rolling the vividly ductile material up the core, whose cross section exhibits the form of a Reuleaux triangle, in particular a Gleichdlcks, with which rolled up material for the compression of the same between Druckkörpern is shifted. This procedure makes the production of the pipe and/or fitting according to invention with substantially higher physical properties more gegenlaber for the well-known Eiprofilrohren possible. During shifting the core with the Matetialbahn between the Druckkörpern, already rolled up, contact constantly exists between the pipe and/or Rohrforrnstück and the Druckkörpern. Without the Druckkörper would drive thereby a reciprocating movement out, an even thrust force can be expenditure-practiced on the pipe and/or fitting, whereby an even compression of the material and thus an optimal ultimate strength of the same will receive. For the practical execution of the procedure it is appropriate that the core with the rolled up Materialbahn between at least two, preferably swivelling, in the distance Druckkörpern into a Umlaufbewegung around its Momentanpo, from each other arranged! is brought, whereby the direction of rotation of the core runs opposite like the direction of rotation of the Druckkörper. It is favourable hiebei, if the axle center of the core and/or pipe or fitting is obligatorily led au£ two per a length of curve of 60° exhibiting circular arcs, which form a Reuleaux lens. In principle also a reverse procedure execution is, i.e. a stationary storage of the core and a circulating movement of the Druckkörper possible; this can be favourable in particular for cores with large dimensions. Further it is favourable, if during the shaping between the core and the Druckkörpern line contact is constantly held and the contact pressure of the pressure rollers is held against the core over the entire length of the line contact essentially equally large, whereby the pressure is changed if necessary during the temporal Verlanfs of the shaping procedure. The device for the execution of the procedure according to invention, with at least two Druckkörpern from each other arranged in the distance, in particular oh savings allele arranged pressure rollers, of which preferably at least one is adjustably stored, and with a core stored between these Druckkörpern, is characterized by that the core in the cross section seen the form of a Reuleaux triangle and/or. Gleichdicks exhibits and in at least one guidance is led, which the form of a Reuleaux triangle and/or. Gleichdicks or a Reuleaux lens exhibits. This device is similar to a usual Rohrmaschlne for the production of pipes from faserhältigem, fleece-similar material. The tubing core with the cross section profile of a Reuleaux triangle and/or a Gleichdicks is appropriate hiebie between that in particular for two Druckkörpern and/or - roll, whereby the lower Druckkörper, e.g. the Brustwalze, is adjustable firmly arranged and the upper Druckkörper, e.g. the so-called Equipagewalze, preferably in the height. For the device according to invention the so-called Equipage can consist also of one or of several rollers and/or pairs of rollers. The Druckkörper are preferably designed as cylindrical rollers, whose axles run parallel to each other and to the momentary axis of rotation of the core. It can do one of the two pressure rollers by a pair of pressure rollers, which is two closely together-lying rollers with smaller diameter than the original pressure roller, is replaced. In this case a small oscillating movement of the pair of pressure rollers arises, which does not have considerable influence however on the procedure. In arrangement of the device according to invention it is intended that the guidance is essentially transverse to the axles of the Druckkörper and/or the core running level arranged in one. In order to secure the core against falling out of the tubing machine, a Kemhalterung is preferably intended at both ends of the core. With this training it is appropriate that the guidance is designed as nuclear mounting plate at the same time. This design of the nuclear holding device is based on the fact that the momentary poles take in each case two positions during the shifting movement of the core between the Druekkörpern. These two positions are appropriate au£ for the connecting straight line of the two printing body centers and have in each case a distance from the extent circle of the Druckkörper, that equally large are with the radius of the threat of the points of the core plus the wall thickness of the pipe already rolled up. In further training of the invention is now intended that the form of a Reuleaux triangle and/or a Gleichdicks exhibiting guidance is trained as recess and/or groove in the axial face of the core, in which two projections/leads from each other arranged in the firm distance, in particular tap intervene, which rests against each other diametrically facing places of the guidance and which holds core. Dahei is formed thus the nuclear mounting plate at the machine in the form of two taps, pins od.dgl, which have to each other the distance of the side length of the Konstrukdons triangle of the Reuleaux triangle and/or Gleichdicks, so that the core is led obligatorily by this device during its shifting movement. During the winding procedure the distance of the two pins remains to each other constant. However if a larger or smaller GleichdickproFll is produced, then the pins must be brought on a new distance, which corresponds to the side length of the construction triangle of the new profile, and which are adapted in the axial Sfirnseite of the core recess and/or groove present of the size of the new Kernqnerschnlttes. With another design according to invention it is intended that the form of a Reuleaux lens exhibiting guidance is designed in a stationary construction unit stationarily arranged and as recess and/or groove, whereby in this guidance three projections/leads from each other arranged in the distance, intervene in particular taps, those with the core is firmly connected and against three, the corner points of an equilateral construction triangle hildenden places the guidance rests. Hiebei are at the face of the core three taps, pins od.dgl. fastened, their centers with the circle of curvature centers of the Kernquerschnittes collapse, which are on the corner points of the Konstruktionsdrelecks. The nuclear mounting plate at the tubing machine is with this design a recess, a template or a guide groove in the form of two to each other curved circular arcs. The radius of the circular arcs is equal the side length of the construction triangle of the Reuleaux triangle and/or the Gleichdicks plus the radius of the pins, taps od.dgl. a larger or smaller equal thick alike is produced, then the side length of the construction triangle and thus the position of the pins in the core and it change must a accordingly changed template as Kernhaltertmg be used. With a further design according to invention, dafl the guidance for the core than four-bar linkage is intended is trained. The center of the core and/or the Konstruktionsdrelecks, which describes two to each other curved circular arcs during the shifting movement, is led by the four-bar linkage zwa_ugsweise, whose crosspoint describes exactly the same K_reisbögen. One of the two cranks of the Gelenkvlerecks can be propelled thereby whereby this drive is coupled with the shifting speed and with it the felt speed of the Rohrmaschlne. For the production of a hollow core it is favourable, if the core is formed by three annulus sections in the cross section seen from two kinds each, whose flank level in each case with one another include an angle of 60°, whereby the annulus sections exhibit a kind a larger radius than the annulus sections of the other kind, and the flanks of the Kreisrlngabschnitte are firmly connected to a kind with the flanks of the Kreisringabsehrdtte of the other kind. The Eriß_ndnng is described below on the basis the designs, in which a remark example of a erfmdungsgemäßen pipe and devices are represented to its production, more near. Fig.1 a look-figurative representation of a pipe according to invention, whose Querschnltt has the form of a Reuleaux triangle, points Figola a scbaubildliche representation of another pipe according to invention, whose Querschrätt has the form of a Gleichdicks, Fig.2 dle construction of the cross section of a pipe with rounded off edges (equalthick), Fig.3 a schematic representation of the shifting movement of the core with the rolled up Materialbahn between two pressure rollers, Fig.4 a schematic opinion of a first design of a device according to invention to the production of the pipe according to invention and/or. Rohfformstückes, and Fig.5 a schematic opinion of another Bau£orm of a device according to invention for the production of the pipe and/or fitting according to invention. In Fig.1 is a remark example of a pipe according to invention --1-- represented, its three sides curved outward --2, 3, 4-- seen in the cross section a Reuleaux triangle to form. The internal, also curved Wandnngen --5, 6, 7-- this pipe form likewise a Renleaux triangle. These two Reuleaux triangles are coaxial and to each other seitenparalle [arranged, so that the wall thickness of the pipe is equivalent thick essentially in each place. In the case of use of this pipe as channel, Drainageund/or thick matter pipe it like in Fig.1 one shows -- with a point of the Renleaux triangle pointing moves downward. Thus ensured, with small throughput quantities a relatively large flow height is given and daß' still sufficient free Querschrätt for extremely large throughput quantities is present. In Fig.la is a Ausflilarnngsbeispiel of a pipe according to invention --1 '-- represented, its sides curved outward --2, 3 and 4-- and curved internal walls --5, 6, 7-- in the cross section seen ever a Gleiehdick, i.e. a Reuleanx pipe with abgernndeten edges, to form. In Fig.2 the geometrical form of the Qnerschrätts of a erEmdnngsgemäßen pipe with rounded off edges is more near described. One proceeds hlebei from a Reuleaux triangle with the sides --2 ', 3 ', 4 '--, which are formed from circular arcs curved outward. The radius --G 1 -- these circular arcs corresponds to the distance of the corner points of the Reuleaux triangle. The Öf£nungswinkel of each circular arc --2 ', Y, 4 '--thereby, to the gleiehseitige triangle, 60° amounts to due. Increases one now the radius --R-S-- this circular arc --2 ', 3 ', 4 '-- around the amount ---R2 --, maintains the opening angle of 60° and closes between the circular arcs --5 ', 6 ', 7 '-- arising gaps with circular arcs --8--, those exactly the radius --R2-- have, then one erhärt a special form of the Reuleaux Dreieeks, which is called equalthick. The centers of the circular arcs --8-- are thereby on the corner points of the original construction triangle. The extreme case of the Gleiehdieks is the circle, if thus from an infinitely small equilateral triangle one proceeds or differently expressed the enlargement --RZ-- the radius --G 1-- in relation to the equilateral construction triangle is very large. In Fig.3 the production of such a pipe is by shifting between two Druckkörpern --D1, D2 -- schematically represented. The core --K-- with the rolled up Materialbahn full-led hiebei between these Druckkörpern a UmlanBewegung around its momentary pole the course described by the axle center of the core, a so-called Reuleaux lens, is represented in Fig.3 with strichlierten lines, whereby three positions --Ms, M2, ms--- are emphasized, which correspond to the also fully taken off lines represented KernsteUungen. This Reuleaux lens consists a length of curve of 60° of two, ever anfa traveler Gleisbögen of same radius --RR---, whereby the distance --A-- the centers equal of these two circular arcs is the double height of an equilateral triangle with the side length ---RR-- (A = 2.RR cos 300). In Fig.4 a first remark example of a device according to invention is represented for the production of the pipe according to invention. This device covers one stationarily, however swivelling stored pressure roller --10--, the so-called Brustwalze, and two in the distance above the same arranged pressure rollers --! 1, 12-- of smaller diameter, their distance regarding the pressure roller --10-- is adjustable. Around the pressure roller --10-- is an endless felt course --13-- led, which a Materialbahn from vividly ductile material, not represented more near, rests upon. Between the Dmckwalzen --10 and 11, 12-- is a core --14-- transferrable stored, whose exhibits cross section the form of a Reuleaux triangle and/or a Gleichdicks. For nuclear mounting plate is in the axial front surfaces of this core --14-- ever a guidance --15-- trained, which exhibits also the form of a Reuleaux triangle and/or a Gleichdicks. The two Reuleaux triangles and/or Gleichdicks are coaxially arranged thereby. At the guidance --15-- lie two stationary taps from each other arranged in the distance --16, 17-- on. The guidance --15-- is hiebei as guide groove and/or recess in the face of the core --14-- trained and the taps --16, 17-- intervene in this groove and/or recess. The pressure roller --10-- by means of a drive device not represented more near toward the arrow 18, and the core is propelled --14-- between the pressure rollers --10 and 11, 12-- in opposite direction, u.zw. toward the arrows 19, shifted. The core --14-- becomes hiebei with his guidance --15-- along the taps --16, 17-- inevitably led. By rolling the material up on the core --14-- it is necessary, the distance between the pressure roller --10-- on the one hand and the pressure rollers --11, 12-- to increase on the other hand. The pressure rollers --11, 12-- are from there regarding the pressure roller --10-- adjustably stored. Is appropriate hiebei, the pressure rollers --11, 12-- to store against spring action and/or application of pressure relocatable. In Fig.5 remark variation in type of a device according to invention is represented for the production of the erfindnngsgemäßen pipe. This device enclosure also one stationarily, however swivelling .angeordnete pressure roller --20--, the so-called Brustwalze, and two in the distance above the same arranged pressure rollers --21, 22-- of smaller diameter, their distance regarding the pressure roller --20--, if necessary under spring action, is adjustable. Around the pressure roller --20-- is an endless felt course --23-- led, on which a Materialbahn not represented more near is brought to the device. Between the pressure rollers --20 and 21, 22-- is a core --24-- transferrable stored, whose exhibits cross section the form of a Reuleaux triangle and/or a Gleichdicks. For nuclear mounting plate are at the two faces of the core --24-- ever three projections/leads in the form of taps, from each other arranged in the distance --25, 26, 27-- attached. These taps --25, 26, 27-- form - in direction toward the face of the core --24-- see-seeing those corner points of an equilateral construction triangle for the Reuleaux triangle and/or. Equalthickly and are along a stationary guidance --28-- led. This guidance --28-- the form of a Reuleaux lens has and dnrch a groove or a recess in a stationary construction unit of the device is formed, into which the taps --25, 26, 27-- intervene. The pressure roller --20-- becomes toward the arrow --29-- propelled and the core --24-- becomes in opposite direction, u.zw in the sense of the arrow 30 between the Druckkörpern --20, 21, 22-- shifted. By into the guidance --28-- decisive taps --25, 26, 27--, which constantly rest all against this guidance, the core becomes --24-- inevitably led. The cores --14, 24-- the Vorrlchtungen according to invention can, as in Fig.4 and 5 suggested, seen in the cross section from two kinds of ever three annulus sections --14 ', 14 " and/or 24 ', 24 "-- are formed. Each of these annulus sections has a length of curve of 60°, however the radii of the individual kinds of sections are of various sizes. These sections can be manufactured in a simple manner by three-division of two pipes of different diameter. If now the flanks of each annulus section a kind of the annulus sections of the other kind neighbouring with the flanks are connected in each case, e.g. by welding, erhäh one a hollow core, whose cross section has the form of a Gleichdicks. The hollow core can be issued inside e.g. with ribs. By use according to formed pressure rollers can in connection with according to trained cores also pipes with angeformten sleeves be manufactured, whereby this Murren in the cross section seen again the form of a Reuleaux triangle and/or a Gleichdicks to exhibit. Further it is also possible to manufacture pipes which exhibit a circulating groove at a stimseitigen end and at the opposite end an appropriate crease. As material for the production of the pipe according to invention come in particular Faserbzw. Asbestos cement, in addition, other bonding agents containing masses such as Knnstharzbeton, clay/tone goat-blaze stoneware masses in consideration, those in the damp condition to be formed in each case and afterwards confirmed and/or. tie. As fittings primarily pieces of sheet, elbow union, approaches are used od.dgl. The Rohrforrnstücke according to invention can be manufactured also with angeformten Murren and/or with groove and crease. PATENTANSPROCHE " 1. Rohrbzw.
