Pig. 5 shows a sectional view through a section a structure built using the construction panels of the present invention is.

From Pig. 1 it can be seen that a plate having the features of the present invention as a construction plate or construction panel is executed and from a body part made of foamed Plastic material 1 and a reinforcement part, which consists of a substantially rigid steel mesh 2 which is at least partially within the body part consists of foamed plastic. The plastic material can be made of a rigid polyurethane foam or consist of a rigid foam made of an isocyanate polymer obtained by mixing diphenylmethane diisocyanate and a mixture of polyols, a blowing agent, Silicone oil and catalysts. In the preferred embodiment According to the invention, this polymer is made by mixing the aforementioned constituents during a spraying process shaped. Although a simple mesh construction, consisting of a network of steel bars attached to the crossing points welded together, other mesh construction materials, for example drawn metal.

A frame 3 is also provided and is formed from suitably shaped pieces of wood. That one edge of the frame 3 forming wooden part has a protruding portion 4, which serves to form two recesses 5 and 6, wherein the recess 5 serves to provide a stop against which a section of the braid 2 abuts. Of the

3098U / 0320

The purpose of the recess 6 will be described later.

The frame 3 is equipped with a bolt opening or hole 7, in order to create the possibility of extending the plate

to be able to attach similar panels

The plate is equipped with a cladding material, which consists of a plurality of tile plates 8 in the illustrated embodiment. It should be emphasized, however, that the cladding material (if it is provided) also made of other materials, such as slate stone »tile material, Marble, asbestos or metal plates ». In the embodiment shown is between the tile plates 8 mortar 9 provided so that the plate from the outside like looks like a conventionally constructed brick wall.

The plate described up to this point can be used as a construction plate or construction plate, as the plate through the Reinforcing braid 2 is very strong · Since the plate is made of a solid foamed plastic material 1, it has very good heat and noise insulation properties. Other panels made from the specific materials previously described have a very high resistance to fire. It can also make similar plates with the help of bolts that pass through adjacent bolt holes 7 are plugged together, thus building up a structure or construction using the previously described plates is very simplified ..

Fig. 2 shows a form in which the pig. 1 shown Plates can be made. The mold consists of an outer rectangular frame 10 and has a substantially flat bottom section 11 and a hinged cover 1,2 ..,

The bottom or base section 11 of the form, which in detail shown in Fig. 3 consists of essentially one

3098U / 03 2 0

flat surface 13 on which a number of ribs 14 are arranged are. The ribs 14 are arranged in a shape, as this corresponds to the shape or the course of the mortar in a conventionally constructed brick wall, and the dimensions of the Portions of the surface 13 between the ribs 14 are chosen to correspond to tiles.

In the following, with reference to FIG. 4, the method for making the panels of the present invention.

4, tile plates 8 are first placed in the mold, and the tile plates are placed between the ribs 14 ^; inserted in such a way that the ribs 14 are adjacent tile panels; separate against each other * There is then a dry mortar be- 15] see the channels given the above between äexi brick tiles! half of the ribs 14 are present. The mold is then equipped with the plate frame 3, the plate frame 3 is provided with the steel mesh 2, which is against the recess 5

ι of the frame 3 abuts. The frame 3 is dimensioned so that it j *

rests directly on the outer frame 10 of the mold, so that the j Frame 3 is held in a substantially rigid position. If desired, a suitable support device can also be used used to ensure that the braid 2 is at a distance from the tile plates 8. In any case, however, the braid 2 is located so that it at least partly in a body portion made of foamed plastic which is manufactured in the mold is supposed to be located.

A spray gun is then used to spray a mixture of a polymeric isocyanate mixture, which mixture from a certain composition of diphenylmethanediisoeyanate and a mixture of polyols, a blowing agent, silicone oil and low viscosity catalysts consists. These components are mixed during the spraying process, and the spray jet essentially creates a

stiff, foamed plastic st off material. Part of the spray passes through the braid 2 and forms sections of the part of the foamed plastic material 1 directly into near the brick slabs 8 and the mortar 15. Other sections of the foam get into the mortar 15 'then harden, so that the mortar 15 then has an appearance or an appearance which is similar to the appearance of the conventional one Way corresponds to mortar mixed with water. The plastic material is in this way with the brick panels, the Anchored in mortar, braid and frame. The spraying is then continued until the plate reaches a suitable thickness Has. The spray jet then foams, whereby a solid foam material is created after the sprayed material into the, Form was introduced. When a suitable amount of the spray has been introduced into the mold, the lid 12 becomes the mold is closed, and a further expansion of the foam material is taken into account by expansion holes 16, which are provided in the lid 12 of the mold. The plastic foam allowed to cure, the mold is then opened and the complete panel is removed from the mold. It openings 7 can then be drilled into the frame parts 3 so that the plate can then be attached to similar plates or can be attached to a support part.

Although the method of the present invention in conjunction has been described with a foamed plastic based on an isocyanate composition, it should be emphasized that that also other foamed plastics for shaping the plates can be used according to the present invention, including in particular foamed polyurethane plastics.

Although the present invention has also been described in connection with an embodiment in which a frame part 3 is provided, it should be emphasized that the frame part 3 does not constitute an essential part of the present invention, and that the reinforcement braid 2 also appropriately extends over the body portion of the foamed plastics material

can also extend, in which case the plate can be fastened in position with the aid of the protruding braid sections 2 can or can be fastened with the help of special fasteners embedded in the plastic itself. If that Braid material should protrude from the perimeter of the panels, so the walls of the mold can be made slotted, or the mold can be formed from two sections to accommodate the sections of the braid, which should protrude at the periphery of the plate.. ·

The walls of the mold can very advantageously with silicone wax or a similar triggering agent prior to the introduction of the foamed plastic material in the form.

According to FIG. 5, a plate as previously described can | de, with a similar plate with the help of a connecting bolt j zens 17 can be connected. The part 3 has two recesses 5 j and 6, the purpose of the recess 5 already described 'Before tightening the connecting bolt, which i connecting two adjacent panels can be a PVC duct j or an insert 18 can be inserted between the recesses 6 of the frame parts of adjacent panels. Similar can also an insert made of plastic 19 can be inserted into the gap between two tile plates 8, these plates being immediate I bar on the edges of the panels to be joined together | gen. The panels can also be connected with support parts, such as the support part 20, which is done with the aid of bolts j (not shown). The support part 20 consists of a [ Part with a substantially square cross-section with a! L-shaped sealing part 21, which abuts on two j the surfaces of said support part, the sealing part 21 extending beyond the sides of the part with a square cross-section and in this way in engages the recesses 6 of the frames of the panels attached to this part. The plates shown in FIG are covered with an inner layer made of plaster or
