Multi-part assembly kit for a non-positive connection in demountable truss constructions

The object of the innovation is a multi-part contact set for a non-positive connection with dismountable Fachwerkkor.s tr uktions from prefabricated, square profiles, especially those for modular systems.

With the previously known releasable connecting elements of a similar type, a seamless corner or cross connection in trusses in 6 possible directions using prefabricated components without the use of protruding connecting parts is not possible. Another disadvantage of the previously known connections in modular systems is that they are not frictional. .Allow arrangements at the crossing points.

The task of the innovation is to create a connection that allows both a non-positive joining of prefabricated profiles and a dismantling of the same and allows reconstruction in another form.

To solve this problem it is proposed according to the innovation that the profiles, which are manufactured in fixed lengths according to a modular system, have welded inserts at both ends which form a 45 inclined truncated pyramid on all sides. The one perpendicular to the longitudinal direction of the profile running area corresponds to the area of a connection cube. This cube becomes the central focus arranged at the joints and has in each of its

6 surfaces several vertically arranged threaded holes. The connection of the profiles with the cube is made by screws through the recesses in the profiles of the Inside are screwed into the cube and thus ü Connect the pyramid-shaped beveled surfaces of the end inserts of the profiles with one another in a non-positive manner. By the arrangement according to the innovation, intersection points can be produced in any right-angled direction.

In a further embodiment, the connecting cube has the same area as the profile to be connected, ie the end inserts of the profiles are kept flat and lie directly on the cube exi.

In the accompanying drawings, the inventive design of the connecting element is shown schematically.

Show it:

Flg. 3 shows a partial section through a connection point without pyramidal beveled surfaces of the end inserts

In Fig. 1, the profiles (l) are inside the profiles welded inserts (2), which form a truncated pyramid with 43 ° inclined surfaces. The profiles are Provided with an opening on one side at (3), which will be explained later is closed in a known way with a lid

The central cube (4) has several vertically arranged threaded holes (5) in the middle on all 6 surfaces.
