    Description: The invention relates to a lightweight board with an upper cover plate extending parallel to a longitudinal plane, with a lower cover plate extending parallel to the longitudinal plane, with a light middle layer extending between the upper cover plate and the lower cover plate, which has a cardboard honeycomb structure, and with at least one supporting edge which extends from the side of the upper cover plate facing the central position to the side of the lower cover plate facing the central position and is arranged in the direction of the longitudinal plane adjacent to the central position.
    Lightweight building boards are well known from the prior art. These have also been used in a variety of ways in furniture and interior design for a long time.
    In the upscale furnishing area, lightweight panels were also used in furniture construction, because their use allows very large wall thicknesses to be achieved, which offer special design options. More recently, lightweight panels have also been increasingly used in mass furniture, so that it can also be used economically in a wider area. This means that the various advantages of lightweight panels are accessible to a larger layer of end users.
    The manufacturer of furniture no longer needs to manufacture lightweight panels itself, as was the case in the past. This required several work steps. First of all, a frame had to be produced, possibly with several crossbars, on which the cover plates were then attached and which had to accommodate the various fittings. Light fiber boards, mineral insulating wool, cardboard honeycombs or the like were inserted between the cover plates. This gave the element more compactness and possibly also improved stability. In most cases, the cover layers also had to be surface-treated in a complex process.
    So veneered or otherwise coated hardboard was common, the finished element can only get its final surface by final painting.
    Today, lightweight panels are increasingly manufactured industrially. For this purpose, a light middle layer is provided with cover plates, mostly by gluing. Depending on the required stability of the board, cover boards of different thicknesses, mostly made of a wood-based material such as chipboard or fibreboard, are used. The boards used can already be coated, for example with a laminate, a color, a print with sealing, a melamine resin layer, a veneer, etc. Cardboard honeycombs or foam sheets are preferred as the middle layers. Honeycomb materials made of materials other than paper or cardboard may also be useful for certain purposes. The thinnest plate materials or thin-walled metal, for example made of aluminum, can be used for this. However, it is also possible to use light wood-based materials such as corresponding chipboard or fiberboard or even solid wood of low density, such as balsa wood, as middle layers. With appropriate recesses, all materials for use as a light middle layer are possible. For example, wood types are also used for this which are not particularly light, but are readily available and can be easily machined with cutting tools. Light middle layers of bundles of stalks, which are cut together to form flat structures so that the length of the stalk sections corresponds to the thickness of the middle layer, are also known.
    On one or more end faces of a lightweight board, bars or frames can be arranged for reasons of stability, which usually consist of a wood material and can absorb relatively large compressive forces perpendicular to the longitudinal plane (plate plane).
    In this respect, the bars or frames thus take over the function of a supporting edge and thereby prevent the light middle layer, which is often made of a cardboard honeycomb structure

    Patent office stands, is damaged at high pressure loads perpendicular to the longitudinal plane.
    However, the said bars or frames, especially if they are made of a wood material, are less or hardly suitable for absorbing other than the pressure forces acting perpendicular to the longitudinal plane, especially when the forces are locally occurring, for example from the front Insert dowels or screws into the lightweight board and the bolt. For example, a dowel can transmit a relatively large moment or a screw can transmit a relatively large tensile force to the bolt, whereby these locally acting loads, particularly in the case of a bolt made of a wooden material, lead to damage and ultimately to an unstable overall construction of the component held together with the dowels or screws, for example, furniture. The aforementioned problem also arises for grooves that extend, for example, to accommodate a rear wall or a drawer into the material of the bolt.
    It is therefore the object of the present invention to provide a lightweight board which has a support edge which can withstand different loads optimally.
    The previously derived and shown object is achieved according to a first teaching of the present invention in a lightweight board of the type mentioned in that the at least one supporting edge has several separate individual layers, the individual layers being glued together, made of a wood-based material in the form of a Chipboard exist and run parallel to the longitudinal plane. Separately means that the individual layers form separate components that are manufactured individually. Only by assembling these individual components, that is to say individual layers, does the support edge used according to the invention then result. In contrast, a support edge made of a wood material that is scattered in several layers and then pressed is not a support edge that has several separate individual layers.
    Especially in the technical field of lightweight panels, the use of a supporting edge made up of several separate individual layers has decisive advantages. It has been shown that several individual layers can withstand higher loads than a simple bar made from a wooden material. This applies not only to the pressure loads perpendicular to the longitudinal plane (plate level) for which the conventional bolts are intended to protect the light middle layer from damage, but also to all other loads, in particular locally occurring loads caused by moments, for example from dowels or originate in grooved rear walls or floors, or by tensile forces that act on the material of the supporting edge, for example from screws. There is then no longer any danger that parts of the supporting edge will break out and thus reduce the stability of the overall construction, even with relatively large loads. Grooves that extend into the material of the support edges, for example rear wall grooves or drawer grooves, but also row of holes, etc., can also be realized in a stable manner. A further advantage is, however, that the use of separate individual layers in the area of the front edge of the lightweight board also enables a non-straight, in particular curved, course of the supporting edge. Since the non-straight course of the support edge can be realized without subsequent removal of material from the support edge, the surface of the support edge and thus the later front edge of the lightweight board is also of higher quality than in the case where a straight ledge made of a wood material is used as a support edge by removing Material must be adapted to the non-straight course. A high-quality surface in the area of the supporting edge leads to better coatability and / or to a reduced risk of moisture penetration.
    Due to the increased stability by using several separate individual layers, the same material can be used for the supporting edge as in conventional bars. According to the invention, the individual layers consist of a wood material in the form of a particle board. When using the same material as was previously used for bars, namely a wood material, the provision of several separate individual layers significantly increases the stability compared to a conventional bar.
    According to a further embodiment of the lightweight board according to the invention
    2.5
    AT15 579U1 2018-03-15 Austrian
    Patent office several, preferably all individual layers of the same length, width and / or thickness. By length is meant the dimension in the direction of the longest extension. By width is meant the perpendicular dimension, which extends in the direction from one to the other cover plate. Finally, the thickness means the dimension perpendicular to the length and height, which can also be referred to as thickness. Individual layers, which have the same length, width and / or thickness, lead to a particularly simple manufacture of the support edge and thus of the lightweight board and result in a particularly uniform distribution of the loads acting on the support edge. However, it is also conceivable for several, preferably all, individual layers to have different lengths, widths and / or thicknesses, as a result of which an individual adaptation to the load situation of a lightweight building board is possible.
    According to yet another embodiment of the lightweight board according to the invention, several, preferably all, individual layers are arranged parallel to one another. In the case of a non-straight course of the supporting edge, the individual layers are preferably arranged over at least part of their length, preferably over their entire length, with a constant distance from the adjacent individual layer. This also ensures optimal stability and power distribution within the supporting edge and lightweight board.
    According to yet another embodiment of the lightweight board according to the invention, adjacent individual layers touch. All adjacent individual layers preferably touch each other, although individual individual layers can also be spaced apart from the respectively adjacent individual layer. By touching adjacent individual layers, the contacting individual layers being glued to one another, loads acting on one of the individual layers, for example tensile forces or moments, are also distributed to the other individual layers and, in turn, to different locations on the cover plates of the lightweight building boards. Thanks to this optimized force distribution, the support edge can withstand particularly high loads.
    As said, all individual layers do not necessarily have to be in contact with the respective adjacent individual layers, but it is also conceivable that an intermediate space is formed between adjacent individual layers, at least one of the intermediate spaces at least partially with air and / or a filling material, in particular a foam that is filled. The supporting edge can therefore also consist, partially or completely, of non-contacting individual layers, the space created between non-contacting individual layers making it possible to reduce the weight of the supporting edge and thus of the lightweight board. In this case, loads acting on a single layer are inevitably also transferred to neighboring individual layers which do not touch this individual layer if the elements which transmit the loads to the respective individual layer, for example screws or dowels, pass through several individual layers and / or are anchored in several individual layers. If it is not guaranteed that in each case the element that transmits the loads to the respective individual layer also comes into contact with other individual layers, or in the case of an additional increase in stability with the lowest possible weight, one of the spaces or more of the spaces between adjacent ones can Individual layers can also be filled with a filling material, for example a foam.
    According to another embodiment of the lightweight board according to the invention it is provided that a reinforcement is introduced or arranged in the material of one or more, preferably all individual layers and / or between two adjacent, preferably between all adjacent individual layers, which in particular fiber material and / or has metal. A layer of nonwoven fabric with a corresponding resin matrix, such as a glass fiber nonwoven or carbon fiber nonwoven in a polyester resin or epoxy resin matrix, can be provided as reinforcement. In this way, the rigidity and the bending strength of the support edge can be significantly increased.
    However, it may also be desirable to provide a very elastic layer in order to give the supporting edge pronounced, tough-elastic properties. For this purpose, a thicker adhesive layer made of an elastic adhesive, which is therefore still elastic even in the hardened state, could be provided, for example made of an adhesive based on silicone or

    Rubber. A thicker layer of adhesive means a layer that is so thick that the adjacent individual layers do not touch, but are movable relative to one another due to the elasticity of the adhesive.
    The supporting edge used according to the invention can in principle be arranged at various locations inside the lightweight board. The at least one support edge is preferably arranged on an end face of the lightweight building board. In particular, two such support edges can also be provided, one of the support edges being arranged on each of two opposite end faces. It can be provided that the outside of the at least one support edge is flush with the front edge of the upper cover plate and / or the front edge of the lower cover plate. Support edges arranged in this way on the one hand cause loads to be transmitted between the support edge and the adjacent cover plate (s) in the outermost edge area, which leads to increased stability and resilience, particularly in the said edge area.
    To further increase the stability, it is provided according to yet another embodiment of the lightweight board that the inside of the at least one support edge touches the central position. In this way, at least to a certain extent, the middle layer can absorb loads from the supporting edge.
    It has proven particularly suitable for a lightweight board according to the invention if, according to a further embodiment, the upper cover plate and / or the lower cover plate are made of a material containing lignocellulose, in particular a wood-based material, preferably a particle board, fiber or OSB board, or from a laminate, preferably with several layers of resin-impregnated paper. Cover plates of such a material are particularly stable and, in combination with the support edge used according to the invention, offer optimum protection of the central position against loads acting over the support edge or over one of the cover plates.
    [0023] According to the invention, the middle layer has a cardboard honeycomb structure. Such a structure leads to a particularly low weight of the lightweight building board and is also suitable for absorbing loads to a certain degree, at least perpendicular to the longitudinal plane.
    A preferred area of use for a support edge made up of several individual layers, as defined above, is in particular thin lightweight building boards. In particular, those up to 19 mm, preferably up to 15 mm, particularly preferably up to 13 mm thick are meant. This is where a firm connection of fitting elements is often important, which is often not possible, especially with thin, single-layer support edges.
    Another preferred area of use for a support edge made up of several individual layers is lightweight boards with thin cover plates. Such cover plates are meant with a thickness of up to 3.5 mm, preferably up to 2.5 mm, particularly preferably up to 1.8 mm. In particular, a firm bond between a stable support edge and the cover plates is required, but this can only be ensured unsatisfactorily with single-layer support edges.
    A particularly predestined area of application for a support edge made up of several individual layers is the combination of thin lightweight building board with thin cover plates. In particular, such lightweight boards are used as shop floors, also known as drawer floors. Especially in the case of drawers or any kind of pull-outs, it is important to have a low overall height and low weight with high load-bearing capacity, whereby a stable connection to the side walls must be ensured, especially since the often considerable loads result from dishes or various items Food.
