lead ', which has the pallet according to the invention.

The invention further proposes that the two above and below lying walls of each hollow slab in certain areas to form are pressed together and welded together from the reinforcement zones to the abutment. The support and spacer bodies are expediently arranged at such reinforcement zones.

Both hollow sheets can be provided with openings through which protrude through the fastening means for the support and spacer bodies and possibly also the ends of the same. The support and spacer bodies can; -by screw bolts extending in their longitudinal direction Or the like. Be present with the two hollow slabs. But it is also possible to provide the support body with a thread at both ends and preferably to be connected to the two hollow panels via a lock nut each. Furthermore, the support and spacer bodies also be provided near their ends with one or more preferably flange-like extensions, which in appropriately shaped Engage recesses of the two hollow bodies.

The design of the support and spacer bodies can be different. So they can each consist of two concentric walls, die.gf. connected to one another by roughly radial ribs' are. But they can also be designed as a hollow body with a simple wall. In addition to the circular cross-section dung-.are also rectangular, square or polygonal in cross-section |:} iOfper · conceivable ... pie. $ Hollow plates can be provided with indentations. ", which serves as a seat for the ends of the support and spacer body? * · An arrangement is possible in which the seat in the ■

According to a further proposal of the invention, the spacers be preferably divided in half in a plane perpendicular to its longitudinal axis. It is possible within the spacer to arrange a cylindrical connecting member extending on both sides of the dividing plane, preferably in one engages groove-like recess attached to both parts of the spacer. The two halves of the body become useful Braced together by a screw bolt or the like, which at the same time the spacer connects in its entirety to the two hollow plates.

Otherwise, however, there is also the possibility of using the two parts of the Support and spacer body to each other in the butt welding process associate. It is expedient to proceed in such a way that first all '' halves of the support body are attached to the respective plate and then the two halves that belong together by means of mirror welding be connected to each other.

The hollow plates can preferably be provided with perforations at the reinforcement areas through which any liquids that may collect, e.g. B. rainwater can flow away. ■ -? '-'- ■'&"'■■''.' ■■ '- ■"■■■■' ■ # - '*''%? ■■., -.-. ■ '-

The pallet 10 shown in the drawing consists of two plate-shaped parts 11 and 12 which are arranged at a distance from one another and parallel to one another and are connected to one another by support bodies which also fulfill the task of VOXi spacers. Each of the two plates 11 and 12 is made of thermoplastic in the blow molding process anyway. The figures 3? 5 and 7 show details of the design of these plates 11 and 12. They are produced in the. Way that a preform, which can be designed as a tube or consist of foils, is introduced into a blow mold and then expanded by a pressure medium until it rests on the mold wall. The pressure medium can be supplied via a blow pin or a needle. The openings that remain in the walls of the PiaftTenvll or 12 are consistently so small that they do not interfere. Otherwise, however, it would also be possible to subsequently close these holes in a suitable manner, e.g. B. to glue or weld. In order to stiffen the individual plates 11 and 12, the upper and lower walls 11a or 11b and 12a or 12b are pressed together in certain areas during the shaping process until they rest against one another. This is easily possible, in particular without an additional work step, since two-part hollow molds are generally used to produce these hollow sheets 11 and 12, which can be designed so that in the course

their closing movement, the pressing together of the two wall parts 11a and 11b or 12a and 12b takes place in certain areas through the molded parts. Some of these stiffeners are located in areas 13, to which the aforementioned spacer and support body attached shd. There the reinforcement areas 13 are essentially circular. In addition, however, it is also possible and useful, regardless of the arrangement of the support and spacer bodies To provide reinforcement areas 14, 15 and 16, of which areas 14 are in the form of short ribs and areas 15 and 16 also, are circular in plan view.

The support body and the connection of the same to the two hollow plates 11 and 12 can be configured differently. At the The embodiment according to FIG. 3 is the support body 17 in cross section designed as a hollow ring, with between the outer and inner he '; Wall 17a or 17b radially extending reinforcing ribs are arranged. This support body 17 is expediently made by injection molding manufactured. The cylindrical space 19 delimited by the inner wall 17b serves to receive a screw bolt 20, which braces the two hollow plates 11 and 12 and the spacer 17 against each other. For this purpose, the two plates are in the Reinforcement area 13 is provided with openings 21 through which the screw bolt 20 can be inserted. Securing the parts and-.their bracing against one another is carried out by an on the a $ End 'of the bolt 20 screwed nut 22. In this way 1st a safe and durable connection of the two hollow plates 11 and 12 possible with each other .. However, the support and spacer bodies and the connection of the same with the two plates 11 and

is explained with FIGS. 5 to 7. Also in Fig. 3 are 12ch the design of the end areas of the support and spacer body and the connection with the hollow slabs have two possible designs shown. At the upper end of the support body 17, the one with the hollow plate 11 is connected, all the frontal boundary surfaces of the walls 17a and 17b lie in one plane. This corresponds to the diameter of the reinforcement area 13 in the hollow plate 11 is approximately the diameter of the support body 17. On the other hand, at its lower end this is designed so that the inner annular wall 17b opposite the outer wall 17a in the longitudinal direction of the support body 17 protrudes. The diameter of the reinforcement area 13 corresponds here approximately to the diameter of the cylinder formed by the wall 1b, wherein'die directly adjoining the reinforcement area 13 Wall parts facing the support body 17, a seat 23 for the protruding end of the cylinder formed by the wall 17b represent. The wall 12a of the hollow plate 12 is shaped in connection with this seat 23 so that an indentation 24 is formed, the Diameter efewa corresponds to the outside diameter of the support body 17. Here, there is a particularly good form-fitting connection between the - • fit & t-z body and the associated plate achieved.

In the example according to FIGS. 5 and 6, this is useful in Blow molding process also made of plastic support and spacer body 117 is polygonal in cross section and at its Both ends of the smaller diameter are provided with an external thread 125. The connection of the two hollow wall parts 11 and 12 with the supporting and punching body 117 takes place in such a way that the threaded Ends 125 are inserted through openings 121 which are attached to the reinforcement area; 13 of the two hollow plates 111 and 12.

are brought. From the outside of the two hollow plates 11 and 12 then lock nuts 126 are screwed onto the thread 125, so that "all parts are braced against one another. These lock nuts' 126 can - like the hollow plates 11 and 12 and the support bodies 17 or .117 - also be made of plastic. - In connection with the embodiment according to FIGS. 5 and 6 are also related to the design of the ends of the support and spacer body z-two possibilities shown. The decrease occurs at the upper end the diameter, which the spacer 117 has between the two hollow plates 11 and 12, to the small diameter in the area of the thread 125 over two steps, the first step starting from the area of the largest diameter adjoining area 127 of the spacer body 117 tapers in the direction of the associated free end, so that since the opposite Wall parts 128 of the hollow plate U run approximately parallel to this, resulting in a perfect fit. This may still be due to this that the polygonal cross-sectional shape of the Support and spacer body 117 also continues into area 127. ■ _. ■

On the other hand, at the lower end the body 117 goes under immediately Interposition of only one shoulder or step 129 in the area of smallest diameter bearing the thread 125. Here required; the bracing of the parts against one another essentially by clamping the edge 130 of the stiffening area surrounding the opening 121 13th

In the example according to Pig. . 7, the supporting and Distanzkörp.er 217 is formed in two parts, wherein the dividing plane extends perpendicular to the longitudinal axis 231 of the body "217 the latter is true with respect to its yuerschnittsform with the embodiment according to FIG 4 match _D.;.. H so that the outer. Wall 217a and the inner wall 217b are connected to one another by radial webs not shown in the drawing 235 of the associated hollow plate engages. This groove-like recess 235 is located a short distance from the stiffening area 13. Since the hollow plates, as already stated, are made of thermoplastic material, it is possible to insert the respective flanges 234 into these groove-shaped recesses 235, although the one on the groove 235 towards the opposite one Hollow slab "closing areas 236 delimit an opening whose diameter is smaller than the largest diameter of the respective flange 1234 · When the flanges 234 are inserted into the JÜTuten-.235, an elastic deformation of the wall of the respective hollow slab takes place in the area 236 .. If the body 217 is also made of plastic, it can be assumed that it is also compressible to a certain extent, in spite of the stiffening that it experiences from the flange 234. Moreover, the arrangement being such that the grooves 235 in the connection to the encryption t strengthening portion 13 lie. That is to say that the elastic deformability of the wall area 236 is not or only slightly impaired by the 5 xe & reinforcement area 13. :

The connection of the two hollow plates, of which in Fig. 7 of the drawing only the top plate 11 is shown, with the support and

■ Spacer body 217 takes place analogously to that already in connection with Fig.

.3 described embodiment by a bolt 220, the inside arranged by a Sgdfci hollow cylinder bounded by the inner wall 217b is. To the cohesion of the overall arrangement, in particular To improve the two halves 232 and 233 of the body 217, a hollow cylindrical section 237 is arranged within the latter, which extends on both sides of the dividing plane 231. To the Achieving a positive connection between this hollow cylinder 237 on the one hand and the two halves 232 and 233 of the spacer body 217 on the other hand, the outer wall 217a of the latter is with a circumferential groove-shaped recess 238 is provided. This recess which has only a small depth, forms a seat for the annular part 237, so that this is secured in its position.

When Äusführun ^ SExample according to FIG. 8, the compound is also assumed that the supporting and spacer body 317 a-us two parts 332 and 333 '. These two parts is carried out, however, by. _J3ciiWBis's * s. With 339 ^is the .Schweissnaht referred to, which can be produced in the butt welding process.

For the sake of simplicity, one is shown in FIGS. 1 and 2 of the drawing Pallet shown in which all of the embodiments shown in connection with Figures 3 to 7 are taken into account. Ie ..- Yalso that the pallet has different support bodies. It isij. ^ se-l of course, impossible and probably also more expedient, on each pallet, all support bodies and connections are to be formed in the same way.
