Definitions
- the invention relates to a flat wall panel at least substantially made of cellulose material.
- the invention also relates to a method for manufacturing said wall panel.
- Such a wall panel is known from German patent No. 2 026 768 (Universal Papertech corp.). Said patent describes a building that is built up of a great many different construction elements, such as a concrete floor, roof and side wall panels made of an intermediate layer of corrugated cardboard sandwiched between two flat outer layers, as well as cramps and corner elements. In practice, the constructional strength of the roof and side wall panels appears to be insufficient to give the building sufficient strength.
- the object of the invention is to improve the wall panel that is known from the aforesaid German patent publication, in the sense that a wall panel having an optimum constructional stiffness is provided for use as a construction element of a building, as a wall panel in, for example, a separation wall, etc.
- wall panel is understood to include an element for use in a wall, a floor, a ceiling, a roof, etc.
- a wall panel of the kind referred to in the introduction is characterized in that the wall panel is at least substantially made of layers of paper/cardboard, each layer at least substantially being made up of a corrugated sublayer and a flat sublayer provided on one side thereof, which layers of paper/cardboard are interconnected via an adhesive applied to the corrugations of the corrugated sublayers, wherein the wall panel is impregnated, in particular with a resinous material, and wherein at least one strengthening layer which is stiffer (i.e. less deformable) than the layers of paper/cardboard is provided, which strengthening layer is connected to a layer of paper/cardboard on one side of the wall panel via an adhesive.
- the whole of various adhered-together layers of paper/cardboard is connected on at least one flat (outer) are side thereof to the stiffer (i.e. less deformable) strengthening layer.
- the wall panel comprises two strengthening layers, which are connected to a layer of paper/cardboard on either side of the wall panel via an adhesive.
- a sandwich construction is obtained, in which the whole of various adhered-together layers of paper/cardboard is connected to a stiffer (i.e. less deformable) strengthening layer on both flat outer sides. The result is an even greater constructional stiffness having a corresponding dimensional stability.
- impregnating the wall panel with, for example, a resinous material not only has the advantage of providing a greater constructional stiffness, but also of providing protection against external influences, such as moisture.
- Said impregnation preferably takes place by means of vapour deposition, spraying or otherwise, said vapour deposition or spraying taking place in a direction parallel to the direction of the "cell structure" of the corrugated paper/cardboard that is used.
- Said impregnation may also be effected with mechanical means, wherein toothed and/or flat rollers are used for pressing the impregnating medium into the paper/cardboard.
- the strengthening layer is made of wood, preferably multiply wood, in particular three-ply wood.
- the wall panel is at least substantially made of an even number of layers of paper/cardboard. In combination with the strengthening layer, this provides a plate-shaped material which is hardly deformable, if at all.
- the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel so as to increase the dimension all stability thereof, so that "warping" is prevented at all times.
- the invention also relates to a method for manufacturing a wall panel according to the invention, wherein the wall panel is at least substantially made of layers of paper/cardboard, each layer at least substantially being made up of a corrugated sublayer and a flat sublayer provided on one side thereof, which layers of paper/cardboard are interconnected via an adhesive applied to the corrugations of the corrugated sublayers, wherein the wall panel is impregnated, in particular with a resinous material, and wherein at least one strengthening layer which is stiffer (i.e. less deformable) than the layers of paper/cardboard is provided, which strengthening layer is connected to a layer of paper/cardboard on one side of the wall panel via an adhesive.
- paper is usually used for lighter types of paper; in the case of a heavier quality, the term cardboard is frequently used.
- the terms paper, cardboard and weight are not intended to be limitative as regards the type of material to be used.
- the aforesaid resinous material with which the wall panel according to the invention is impregnated is preferably an epoxy resin, a polyurethane resin, a polyester resin or a phenol resin. Fire-resistant and/or fire-retarding agents may be added thereto.
- the resinous material with which the wall panel according to the invention is impregnated also functions as an adhesive for adhering two layers of paper/cardboard together, so that a separate adhesive, such as a glue, is not required.
- sets consisting of a corrugated sublayer and a flat sublayer provided on one side thereof, which sublayers are already impregnated with the resinous material, can be placed on top of each other so as to be adhered together (after the resinous material has dried).
- Fig. 1 is a schematic, perspective view of the present wall panel
- Fig. 2 is a detail view of Fig. 1
- Fig. 3 is an exploded view of the wall panel of Fig. 1.
- the figure shows a flat wall panel 1 according to the invention in the form of a "sandwich", in the sense that a core 2 built up of several layers of corrugated cardboard is connected on either side to a stiffer strengthening layer 3 of multiply wood, in particular three-ply wood.
- corrugated cardboard four layers of corrugated cardboard are provided, which are each built up of corrugated sublayer 4 and a flat sublayer 5 glued to one side thereof, using a glue applied to the corrugations 6 of the corrugated sublayer 4.
- the core 2 is impregnated with a resinous material.
- the strengthening layers 3 are glued to both sides of the core 2.
- the wall panel 1 is mirror symmetrical with respect to a central longitudinal plane 7 of the wall panel 1.
- the wall panel may exhibit a (slight) curvature, whilst the wall panel may also comprise a curved longitudinal edge.
