Description

DETAILED DESCRIPTION OF THE INVENTION The invention provides that the longitudinal edges are designed so that they can be joined in the longitudinal direction to fit with the longitudinal edges of adjacent structural elements, and that the a rigid foam core and, in particular, metal, in such a way that a material is provided in which a screw can be screwed in each case for internally connecting the connecting element and the substructure, and the said longitudinal edge and a covering layer which is rounded in the area of .

In the tongue-and-groove longitudinal connection known, for example, from German Utility Model No. 1986169, the inner covering layer is held by means of abutment arms and screws. A synthetic profile is required for the transmission of forces to and connection to the outer covering layer. Parts of such construction cannot be used as composites without the use of such synthetic profiles. This is because high point loads occur in the connection area, which can lead to destruction of the component. However, internal screwing is often used - mainly for optical reasons,
They tend to be applied, for example, for reasons of improving the appearance of the screwed part and avoiding local deformations in the area of the fastening part.

Known composite materials with foam-molded padding for force reception require that the resistance point be precisely determined before production, and that it is no longer possible to change this resistance point. There are drawbacks. If the substructure parts are later changed or tolerances are exceeded, this patch no longer corresponds to the structure of the composite and is no longer usable. This drawback has heretofore been avoided by using foam molded, consistent strip padding. However, since this patch is only connected to the substructure part at the intersection point, only about 2-3% of the installed patch is used, thus making the composite material unnecessarily expensive. becomes.

Taking these points into consideration, the problem underlying the present invention is to create a composite material that can induce a large fixing force by internal screwing even in a composite material that does not use synthetic materials. be.

According to the invention, the above-mentioned object is achieved by providing a composite material of the type detailed at the outset, in which each patch consists of a fastening lamella which is later screwed into the rigid foam core from the longitudinal part, the fastening lamina being screwed into the rigid foam core. This is achieved by extending within the core essentially parallel to the covering layer.

With the configuration according to the invention described above, the fixing thin plate forms a large force-receiving surface, thereby reducing the surface pressure contact and thus making it possible to transmit large forces.

Another advantage of the invention is that it simplifies its use, especially in continuous composite elements, by attaching longitudinal edge fixing lamellas.

No matter what composite material is used or the spacing between the lower structural parts, the most suitable fixing point can be selected depending on the implanted padding material, and it can be used as a padding material.

In the embodiment according to the invention, at least some of the fixing plates form long legs of a plate part that is U-shaped in cross-section and has legs of different lengths, both legs being driven in. It has a sharp part,
The thin plate portion is then arranged in such a way that the U-shaped web rests against the longitudinal edge of the composite material.

In the case of a tongue-and-groove longitudinal connection, the U-shaped lamellas have their short legs inserted in the region of the longitudinal edge into the molding formed by the chamfering of the upper coating layer. It is designed to be inserted inside the device.

This holds the upper covering layer, for example, by engaging the shorter leg in the edge molding of the upper covering layer during a tongue-and-groove connection. At the same time, this arrangement also retains the upper covering layer on the tongue side.

Driving into the covering layer is greatly facilitated by the provision of a plurality of driving sharps of different lengths on the short legs of the sheet metal parts.

The invention will be explained below with reference to embodiments illustrated in the accompanying drawings.

1 and 2, a composite material 2 consisting of a rigid foam core 3 and upper and lower coating layers 4, 5 prepared for a continuous tongue-and-longitudinal connection 1 is threaded. It is screwed to the substructure 9 by threaded screws 6 and fixing plates 7, 8 driven into the rigid foam core 3.

The fixing thin plate 7 driven into the tongue side 10 has a driven sharp part 11 and is formed to have a smooth surface. The fixing plate 8, which is U-shaped in cross-section, has its short legs 12.
and a driving sharp portion 13 provided on this leg.
- Among these driving sharp parts, the central driving sharp part has a relatively long dimension.
into the formation of the upper covering layer 4.

Assembly is performed as follows. That is, holes are drilled through the rear substructure 9, the lower cover layer 5, the rigid foam core 3 and the fixing plates 7, 8, which are arranged in a continuous composite material 2. A screw 6 with threads is then screwed into the hole. When using the U-shaped substructure 9, clamping pieces 14 are used to facilitate assembly.
