Device for connecting structural parts

The invention relates to a device for connecting building parts, in particular for forming ceiling structures, consisting of beams arranged parallel to and at a distance from one another, in particular in the form of I-beams, and ceiling beams arranged transversely thereto, in particular in the form of web beams or I-beams, or vertically arranged supports, wherein fastening elements for connecting the components are arranged at the ends of the ceiling beam and at the connection points of the beam or the support.

It is known to date that such connections between structural parts can be made by welding flange plates to the ceiling beam or column, if necessary in notched areas.

which then have to be connected to the vertical web of the beam or a support to be connected with screw bolts. Angle fastenings are also common and must also be fixed using screw bolts. Such fastening methods are disadvantageous in that a relatively large number of individual parts are required to connect the structural parts, and the ceiling support or similar must also be notched at both ends. In addition, a high level of assembly work is required, which is not only costly but can also be dangerous for the assembly personnel.

Based on this prior art, the invention is based on the object of creating a device of the generic type that enables a simple connection of such structural parts, whereby the assembly can also be carried out in a simple manner using a crane and, in addition, as few individual parts as possible that can be lost are required to create the connection.

To solve this problem, the invention proposes that a fork hook is fixed, in particular welded, to the front sides of a beam or ceiling beam as fastening elements, and an abutment is fixed, in particular welded, to the connection point of the beam or support, which can be gripped by a fork hook in such a way that the fork tines rest on both sides of the abutment and the fork web connecting the fork tines grips over an upstand of the abutment.

Preferably, the fork hook is made of a material cut that is approximately triangular in side view

one of the legs of which is welded to the front side of the beam or ceiling beam and preferably extends over the entire height of the beam or ceiling beam, the other leg of which is parallel to the longitudinal extension of the beam or ceiling beam and preferably aligned with the upper edge of the beam or ceiling beam and the hypotenuse of which runs obliquely from the lower edge of the beam or ceiling beam to the leg which is parallel to the longitudinal extension of the beam, wherein in the corner area of this leg and the hypotenuse, the fork hook protrudes under the hypotenuse with fork tines pointing vertically downwards in the assembly position.

Furthermore, it is preferably provided that the abutment consists of a substantially cuboid-shaped piece of material welded to the vertical web of a beam or a support, the width of which corresponds to the clear distance between the forks and which, in the assembly position, has a U-shaped recess on its upper side.

which runs transversely to the longitudinal axis of the beam or ceiling beam to be connected and whose channel flanks directed transversely to the beam or ceiling beam to be connected form an upstand for the inserted fork web that is effective in the direction of tension and in the direction of compression of the beam or ceiling beam.

The design according to the invention enables a simple connection of structural parts. It is only necessary to attach a fork hook to one structural part, preferably by welding, and to attach a corresponding abutment to the other component, preferably by welding. This does not require the beams to be notched, but the connecting elements can be welded to the front of the beams or to the web of the beams. The elements can be welded on the ground in preparation for assembly or in workshops. The elements prepared in this way can then be easily connected to one another on site.

The design according to the invention achieves a virtually articulated connection of the structural components, which is sufficient for a large number of connections.

An embodiment of the invention is shown in the drawing and described in more detail below. It shows:

Fig. 1 An embodiment of the invention in view; Fig. 2 also seen in section II-II of Figure 1.

In the example, a device for connecting building parts is shown. This is a ceiling construction consisting of parallel to and with

Spaced apart from one another, the beam 1 is an I-beam in the example, as is the ceiling beam 2. Fork hooks 3 are welded to the front of the ceiling beam 2 (only one is shown) as fastening elements, and an abutment 4 is welded to the connection point of the beam 1, which can be gripped by a fork hook 3 in such a way that the fork tines 5 rest on both sides of the abutment 4 (see in particular Figure 2) and the fork web 6 connecting the fork tines 5 grips over an upstand 7 of the abutment 4.

In the exemplary embodiment, the fork hook 3 consists of a material cut that is approximately triangular in the side view according to Figure 1 (right-angled triangle), one of whose legs 8 is welded to the front side of the ceiling support 2 and extends over the entire height of the ceiling support 2. The welded connection is made both on the web of the support and on the overlap area of the legs. The other leg 9 runs

parallel to the longitudinal extension of the ceiling beam and is aligned with the upper edge of the ceiling beam 2. The hypotenuse 10 runs approximately from the lower edge of the ceiling beam 2 to the cathetus 9 at an angle, whereby in the corner area of this cathetus 9 and the hypotenuse 10, the fork hook 3 protrudes from the underside of the hypotenuse 10 with the fork tines 5 pointing vertically downwards in the assembly position.

The abutment 4 is formed from a substantially cuboid-shaped material cut welded to the vertical web of the beam 1 and also to the lower cross web of this beam 1. Its width corresponds to the clear distance between the fork tines 5. In the assembly position shown in the drawings, the abutment 4 has a U-shaped recess on its upper side (see in particular Figure 1) which runs transversely to the longitudinal axis of the ceiling beam 2 to be connected and whose channel flanks directed transversely to the beam 2 to be connected form a groove in both the tensile direction and the compressive direction of the ceiling beam.

effective upstand 7 or 11 for the inserted fork bridge 6.

The corresponding connecting elements can be easily welded on in workshops during the preparation of the beams, supports or the like. On the construction site, all that is required to connect the elements is a simple hooking, without the need for removable fastening devices or the like to create the connection.

As shown in the drawings in solid or dashed lines, ceiling beams 2 of different web heights can be connected to beams 1.

The invention is not limited to the embodiment, but is variable in many ways within the scope of the disclosure.

All new individual and combination features disclosed in the description and/or drawing are considered essential to the invention. , -
