Composite panel for installation floors

The invention relates to a composite panel, which is made of individual interchangeable on supporting structures in their edge or So-called installation floors formed in the corner zones of resting panels are intended, and which consist of a panel made of compressed wood chipboard or a similar wood-containing material, which on its side facing away from the load and / or is inextricably connected on its side surfaces with reinforcements made of metal.

Such a composite panel, in which the tensile forces that occur during loading due to the deflection of the panel essentially taken up by the metal reinforcement is known from British patent specification 941 056 which concerns an installation floor in which the parts of the side surfaces of the individual panels made of wood-containing material immediately after laying in contact with each other «In order to obtain a seamless floor, it is necessary to place the side surfaces of the composite panel to process extremely precisely, which is time-consuming and expensive is.

The invention is based on the object of designing a type mentioned at the outset in such a way that

that dimensionally stable and smooth side surfaces without complex Processing measures are achievable.

To solve this problem, it is proposed according to the invention that on the rare surfaces of the board made of wood-containing material, which in this case, e.g. by sawing, Can be relatively rough machined from castable thermosetting liquid plastic, e.g. made of epoxy resin, to cast a frame, whose surfaces are in use a well-made Oießfore without any further processing be sufficiently dimensionally accurate and smooth.

From the American patent 3 2j56 018 are Composite panels for installation floors have already become known, the side surfaces of which are partially formed by a frame made of plastic, but the frames are made of Prefabricated profile strips formed, which can be plugged onto free-standing parts of metal base plates are. It is clear that this will result in any accuracy of the Base plates cannot be compensated.

When composite panels are used in which the side surfaces are made of a wood-containing material Panel are formed by upturned edges of a sheet metal attached to the underside of the panel, a can according to the invention The molded plastic frame can also be used to anchor the bent sheet metal edges.

The Pig. 1 and 2 show in section and in view from below an execution game, in which one with the underside of the plate connected sheet metal reinforcement has bent-up edges, which are embedded in a cast plastic frame.

a profile frame reinforced composite panel.

The composite panel according to FIGS. 1 and 2 consists of one Wood chipboard 10, a sheet steel arranged on the tensile side and a covering 30 made of plastic, linoleum or the like. The sheet steel has a series of indented perforations 21 with inwardly waving perforated edges 22 on "which can be produced in the familiar catfish" by placing the still unperforated sheet on a sheet with holes provided plate and with the help of thorn-like, pointed tools, the holes are pressed in, whereby Bend the Bleohrtnder in the desired way to form a - as can be seen from the drawing - jagged Face. The perforated sheet thus produced is, after an adhesive has been applied beforehand, if necessary, in the wood chipboard 10 pressed in. The sheet metal reinforcement 20 has curved edges 26 with holes 27 and bent ends 28 * which are anchored in a frame 40 made of plastic are. This frame is produced by casting, with liquid plastic, as indicated at 41 in FIG. 4, in penetrates the pores of the chipboard 10, creating an excellent anchorage.

In the example according to Flg. 2, only the side surfaces of the panel 10 are reinforced by metal sheets 20, which, as they are in In relation to the direction of attack of the load, stand on edge, significantly increase the flexural strength in the edge zones. The molded plastic frame 40 covers the metal sheets 20 partially.

In the example of FIG. 4, the board 10 rests in one L-profiles composed of tracks 29, which is a has sufficient strength. A plastic frame 40 is also cast on here.
