Description

The invention relates to a support structure for a suspended ceiling, the support rails attached to hanging members which are connected to one another by connecting links and which have a suspension part, a hollow box-shaped central part serving to receive the connecting links and one thereon have adjoining fastening part.

Such a supporting structure is known from the German utility model 1914 803. This supporting framework consists of longitudinal support rails running through in one direction and arranged between them Cross support rails, which are connected to the longitudinal support rails at the joints.

This connection is made by means of C-shaped connecting links bent from sheet metal, each through recesses provided in the central part of the longitudinal support rails are passed and the engage in the middle parts of the connecting rails on both sides. Through this training of the supporting framework and the connecting link are only such training of nodes possible, from which the mounting rails in ucr extend mutually perpendicular directions. The lay of the connecting links is only here secured by resilient notches, which thus also the Rigidity of the supporting structure in the node! influence.

The invention is based on the object of L-in To train the support structure of the type mentioned so that even with different Ausbilduiivv; i the nodes a permanent and rigid connection between the mounting rails will be educated.

According to the invention, this object is achieved in that the connecting links each consist of rr.lmi. at least two identical connecting parts are formed. ;. those in the respective middle part of the butt; the ends of the! Have support rails engage and there in each case a w see located recess. _!: >. which inserted an expansion body through a hole in the upper wall of the corresponding central part;.: ·. ·. is. Because of the respective subdivision of the connecting links into at least two identical connecting parts, these are easy to manufacture and can be used in a variety of ways. Two straight connecting parts form a connecting link for connecting two support rails which abut on one side and a straight connecting part together with two angled connecting parts ¹ ! serve to connect three support rails that abut one another at the end.

Four angled connecting parts are used to connect four abutting support rails used. By means of the expansion body there is any play between the connecting parts and easy to remove the mounting rails, creating a solid connection between the mounting rails is to achieve. The individual connecting parts are simple and therefore inexpensive to manufacture. she are easy to assemble, can absorb large forces and have a long service life. Further Advantageous embodiments of the support structure according to the invention are the subject of the claims 2 to 5.

In the drawing, exemplary embodiments according to the invention are shown and explained below. It shows

Fi g. 1 is a plan view of a support structure,

F i g. 2 shows an excerpt from FIG. 1 in larger Scale,

Fig. 3 is a side view of the section according to Fig. 2,

F i g. 4 a connecting member for connecting support rails and

F i g. 5 a connection of three abutting mounting rails.

A support rail 1 made of steel, aluminum or plastic is used to produce the support frame. whose profile from FIG. 3 can be found. The mounting rail 1 has on its upper in the installed state Side a cross-sectionally U-shaped suspension part 2, a hollow box-shaped arranged underneath Middle part 3 and one in cross section as well

U-shaped fastening part 4. The walls of the mounting rail 1 are about the same thickness. The upper wall 5 and the lower wall 6 of the middle part 3 serve at the same time as the bottom of the suspension part 2 and as the bottom of the fastening part 4. This middle part can be the same width or narrower than the suspension part 2. The fastening part 4 is wider than the central part 3, so that a shoulder is formed for placing a ceiling plate, not shown, which is in the Support frame according to Fi g. 1 can be introduced from below and without special fasteners Is held in place.

The in F i g. 2 support rails abutting one another at their ends are denoted by 11 to 14. They have the profile shown in Fig. 3 and i £ taper to a point at their ends. Three abutting support rails marked 12, 15 and 16 are shown in Fig.5. The mounting rail runs here 12 pointed and the support rails 15 and 16 are beveled on .iiier ropes. Two "next to each other a abutting support rails, not shown, collide with perpendicular end faces. It can other limits can also be chosen.

To connect the in F i g. The ends of the support rails 12, 15 and 16 shown in FIG. 5 are used by a connecting member 17 (FIG. 4) which is composed of three connecting parts 18, 19 and 20, of which the connecting parts 18 and 19 correspond to one another. The connecting part 20 is straight ^: ldet and narrower at its ends than the rest of the loading; rich. This makes it easier to insert the connecting part 20 into the central part 3 if another connecting part is already located therein. In addition, the ends 21 of the connecting part 20 are reinforced on at least one side perpendicular to the plane of the drawing. The thickness of the ends 21 is such that the ends 21 fit with a tight play in the middle part 3, while between the other parts 70 and the middle part 3 there is a large connection ^ .b 20 undl uun ^
