Both Connecting elements according to the F i g. 32 and 33 are so-called octagonal connectors, while the Connecting elements according to Figures 30 and 31, respectively are so-called hexagonal connectors.

According to a further variant, corner or cross connections of wall parts can also be made without one or more of the connecting elements shown in FIGS. 25 to 33 requirement. For this purpose, a correspondingly angled or multi-armed shape of the plug-in elements is required, such as

in siez. B. from Fig. 14 to 16 can be seen. In Figs. 12 to 16 Different aluminum profiles are shown, which are the starting material for the various variants can form of plug-in elements. It is only necessary to have these profiles at the appropriate length

ii to saw off and then, z. B. by punching or Milling to work out the plug-in arms. The profile of FIG. 13 results, for. B. from the Fi g. I to 6 and 10 visible flat plug-in elements. With the profile according to FIG. 15, plug-in elements can be used for connection

> n of wall parts, one of which is another wall part branches off. Plug-in elements produced from the profile according to FIG. 16 form intersection points of four wall parts.

Those from the profiles according to FIGS. 12 to 16

'■) various plug-in elements that can be produced are in 37 illustrates particularly well in a perspective representation. 37 also shows the various possible combinations of two different plug-in elements, each with

can be realized in any angular positions. To connect two plug-in elements in each case, bolt elements 62 according to FIG Figs. 5 and 6 serve.

The profile of Fig. 12 is also suitable that

ji starting material for hinge-shaped plug-in elementsc as shown in FIG. 17, 18 and denoted by 80. As shown in Fig. 17, the hinge formed by the central part 49, which in the case of the single Sicck element located on the right and numbered 81 is milled out in the middle, so that a recess 82 results. The other one on the left Individual plug-in element 83, on the other hand, is machined by milling at 84 and 85. In the FIG. 17 can be seen The two single plug-in elements 81, 83 by means of a threaded bolt that can be seen from FIG. 20 and is designated by 86, as well as the nut 69 be held together pivotably against each other. Of course, the above can also be used for this mentioned threaded bolts 65 designed as adjustable feet

so find use.

17, however, creates yet another vanante demonstrated, which consists in the fact that two hinge-like Plug-in elements 80 - in turn rotatable relative to one another - by means of a threaded bolt 87 and nuts 69 can be summarized. With the hinge-shaped plug-in elements 80 according to FIGS. 17 and 18, Connect walls that are to be built in alternating directions or angles to each other, namely without loosening the connector. A special application is z. B. the cultivation of cabinet doors on shelves.

The application example according to FIG. 36 is characterized in that an eight-armed plug-in element 95 has been used. This consists - similar to the planar plug element 44 - of two four-armed Individual plug-in elements 96, 97 which are coupled to one another by a bolt element 62. Through the lower Part 96 of the plug element 95 are four wall panels 98

to 101 connected to each other in a cross shape. Through the upper part 97 of the plug element 95 can then above four more wall parts can be added (not shown). The angled plug-in element 88 also enables a right-angled attachment of a further wall part to the wall part 100.

FIGS. 21 and 22 illustrate the construction of a retaining element, wherein as a starting material in the l i · g. 22 aluminum profile shown in section is used. The profile is mitred and joined at right angles. The connection is made by steel angles 102, 103 which are pushed in and glued to the profile. The holding points for the sealing elements (not shown) are designated 104, 105. The retaining element shown in FIGS. 21, 22 is characterized by easy assembly, great angular accuracy and - as a result of the two opposing steel angles 102, 103 glued in - by great twisting stability.

The holding element according to i ι g. 21, II can either - similar to the embodiments described above - be provided only at the corners of the relevant wall parts. But it is also an alternative possible, the holding element - as in F i g. 21 indicated - to be arranged around all four edges of a wall piece. It is also possible to use the circumferential retaining element itself as a wall part or

■> insert frame, the latter with or without filling, the aforementioned high dimensional stability of the holding element has a very favorable effect.

F i g. 23 shows an application example for hinge-shaped plug-in elements 80 according to FIGS. 17 and 18. The

ίο Edges 106, 107 of two adjacent and Wall parts 108, 109 connected to one another by the plug-in element 80 are beveled at 7.5 degrees in each case. This creates a bend in the body of the two wall parts 108, 109 of 15 degrees. at larger chamfer of the edges 106, 107 are in correspondingly larger bends of the wall parts can be achieved.

FIG. 24 shows how such beveled wall parts can also be placed flat against one another.

; n Here, rigid plug-in elements are used, as can be seen, for example, from FIGS. 1 and 2 and denoted by 44 there.
