Building panel and method of making it. V

The invention relates generally to a building panel and the method for its production, and more particularly to a method for producing a building panel from synthetic resin, "". - -: .- .. '. ^_': - ■■ .._. "'"'."

Synthetic resins such as polyurethane are recognized for their excellent insulating properties, and for their excellent durability and durability. Usually - ■■ '■ the polyurethane foam resin from the building material _v ZaB »of plywood, layers often ufflgetoeii ^ Hitrdurcii is made use of the excellent insulating properties of Polyurethaiaschaiunhara =» The plywood was necessary, however. since the polyurethane foam lacked the structural strength that

Polyurethane and other synthetic show wharfs have already been made Formed into building boardsTip-shaped foams are brittle and, as stated above, have no structure at all * Strength on "piping flatten", for example not used for intermediate walls, but mainly where strength and brittleness are of no importance, only as a wall cladding over a plasterboard.

A fired synthetic resin building board is used for the creation uses »which have excellent abrasion resistance properties, Yersehlel's strength properties and Isolle properties foamed synthetic hair and also has the necessary strength and rigidity to withstand the stresses to withstand the stressed building panels, B.Bt with intermediate walls, occur

The plate can also be made using a seaming technique be made »in which a syringe has a mixing nozzle so that the material is mixed and poured into the plate shape can be filled.

A plate according to the invention is produced by making a The foamable mixture of 100 parts by weight of resin and 87 parts by weight of prepolymer increases violently and at 25.6 ° ö (78 ^) stirs, then the mixture is poured into a mold · The mold is provided with the lid and closed. After completion the foaming and the subsequent curing is the Mold dismantled, the Hatrizeneinsats removed and the finished smooth partition panel is ready for installation.

For the production of the foamable (polyester or polyether *) polyurethane mixture for use in the invention, see the semi-prepolymer or the "Ne-Shot-Technique" (binary step process ) . In the Seaiprepolymerverfährsn all the polyisocyanate that is used in the mixture is used is pre-soaked with a rope of the active hydrogen-containing compound required for the final product and the reaction is allowed to proceed between these two components. The resulting seaiprepolymer is then thoroughly mixed with the remaining composition ingredients and the remainder of the active hydrogen-containing compound to produce a foamable compound · OfBQfNAL

In the "Qne Shot Process" everyone is responsible for the composition required ingredients initially, vigorously mixed, so that the basic ingredients are converted into a foamable mixture in a single step.

Another advantageous aspect of the invention results from Figures 5 and 6. The load-bearing panels or load-bearing panels 11 of the invention have a veneer facing 38 attached to them. This veneer facing or front can give the appearance of Ho ^ s, Hegel, Marble, tiles, and other similar materials are made of wood.

The strips 128 are bent in both directions to provide a better connection between the body 120 and the grid 122. The outward bending of the strips 128 opens passages 131 which enable a better union to be formed between the two halves of the body 120 on each side of the grid 122 and thus protect against lateral stress on the plate 111 in the plane of the grid 122. Otherwise such shear stress can occur if the load on the plate 111 between the rails 116 and 117 lies somewhat outside the line connecting these rails.
