    REINFORCED BOARD
    FIELD OF TECHNOLOGY
    The technical solution relates to a reinforced board made of hard wood, which is intended as flooring for indoor and especially outdoor floor surfaces.
    PREVIOUS STATE OF THE TECHNOLOGY
    The problem of floor coverings that increase the living comfort and well-being when walking or lingering is very extensive. Floor coverings are manufactured in three basic variants with reference to climate use, namely outdoor floor covering, indoor floor covering and universal floor covering.
    The shape, material and physico-chemical properties of floor coverings are mainly related to the extent to which the floor should be resistant to moisture, temperature fluctuations, mechanical damage caused by walking or foreign bodies. All this plays an important role in the choice of material, the type of installation, the use of insulation and insulation layers, as well as surface treatment or covering with a top layer, for example in the form of linoleum.
    From an aesthetic and thermal point of view, the most popular floor coverings are made of wood, in a cheaper variant made of wood-plastic with wood decor. The aesthetic potential of wooden floorboards is undeniable, but the use of natural wood also has disadvantages, which mainly lie in the very specific properties of this material. The main disadvantage is the relatively low hardness compared to cheaper types of wood, and also very low moisture resistance. In order to improve the performance characteristics, especially outdoors, it is therefore advantageous to choose hardwood floor coverings of the type such as oak or acacia, which are characterized by high strength and hardness, as well as good moisture resistance. In order to improve their useful properties, it is possible to apply impregnations or surface coatings in the form of varnishes or resins, etc. to these floor coverings, of which probably the best known are the classic oak parquet floors, which are connected according to the tongue and groove principle .
    However, what is advantageous for a longer lifespan of the finished floor, ie. I. the hardness of the wood, on the other hand, is a major disadvantage for the manufacture of wooden floorboards, which often requires the use of metalworking machines instead of woodworking machines for machining and making grooves in the wood. Also, the shape of the trees that provide hardwood is more complex, in contrast to larch or spruce, which are typical softwood species, and it is rarely possible to obtain a sufficiently long and straight section to create a long plank. Therefore, the long planks of the floor structures generally consist of a number of shorter individual planks which are connected to one another, for example by teeth, with this toothed connection additionally being provided with a layer of connecting adhesive. This allows us to get sufficiently long planks with sufficient strength. However, the disadvantage of these connections is their deterioration over time due to temperature fluctuations and oxidation of the adhesive chemical mixture. In addition, long planks are also prone to twisting due to moisture and heat. This can be limited by choosing the type and density of anchoring the planks to the supporting structure, but this is still not entirely impossible, and in the end it is always necessary to replace a plank with a new one.
    The task of the present technical solution is to produce such reinforced hardwood plank, which would be much more durable, while the dimensional parameters of the whole plank remain unchanged. At the same time, the task is to create a device
    which strengthens the plank and can reduce the possibility of plank crumbling at the point of dovetail joints and plank twisting due to moisture. The device used to reinforce the planks must not spoil the aesthetic appeal of the floor and the wood as such, excessively increase the price of the slabs and, above all, significantly increase the life of the planks.
    PRINCIPLE OF THE TECHNICAL SOLUTION
    The disadvantages of the prior art are overcome by the pending reinforced floorboard which, thanks to its reinforcement, is mainly intended for outdoor use. The reinforced plank applied for here consists of at least two individual longitudinal planks made of natural hardwood, these longitudinal planks being connected to one another in the transverse direction by a joiner's connection. The reinforced plank in this embodiment has at least one recess on the underside at least part way along its length which is provided with at least one pair of lower grooves. A planar reinforcement is accommodated in the recesses mentioned, which consists of a base plate with at least two longitudinal projections fitting into the lower grooves. The lower grooves are arranged in the longitudinal direction of the reinforced board.
    In a preferred embodiment, the longitudinal plank is made of acacia wood.
    In another preferred embodiment, the reinforced plank is provided with at least one lateral groove along its longitudinal sides. The side groove is used to connect several reinforced planks with side tongues.
    In a further preferred embodiment, the areal reinforcement is formed by a base plate in the form of a thin prism. The longitudinal projections are located on two opposite upper edges on the base plate, with the two longitudinal projections being arranged parallel to one another.
    In the following preferred embodiment, the areal reinforcement is formed by a base plate in the form of a thin prism. At least three longitudinal projections are arranged on the base plate such that two longitudinal projections are arranged on two opposite top edges of the base plate and the remaining longitudinal projections are located at regular intervals on the upper side of the base plate in the space between the two outer longitudinal projections. All of the longitudinal projections are arranged parallel to one another on the base plate.
    In another preferred embodiment, there is a layer of adhesive between the longitudinal plank and the surface reinforcement. This layer of adhesive material is applied at least to parts of the mutual contact surfaces of the longitudinal plank and the surface reinforcement.
    In a further preferred embodiment, the reinforced floorboard is additionally provided with anchoring elements. In this preferred embodiment, the areal reinforcement is simultaneously provided with through openings through which anchoring elements run. This leads to a further firmer anchoring of the surface reinforcement to the longitudinal board.
    In another preferred embodiment, the areal reinforcement covers at least a part of the transverse width of all longitudinal planks that form an overall reinforced plank. At the same time, the planar reinforcement covers this width over the entire length of the reinforced plank. This results in an overall reinforcement of the reinforced board, which primarily protects the board against twisting and bending. At the same time, all carpentry connections located on the reinforced floorboard are reinforced.
    In the following preferred embodiment, the areal reinforcement covers at least part of the transverse width of two adjacent longitudinal boards. At the same time, the planar reinforcement covers at least part of the length of these two adjacent longitudinal boards at the points of their mutual connection. The planar reinforcement covers
    thus the carpentry connection by which the two longitudinal planks are connected to each other.
    The main advantage of this technical solution is that the original longitudinal planks are reinforced, which were previously connected in the form of floorboards only by one of the joiner's joints. Then, over the years of use, these connections deteriorate and due to fluctuations in humidity and temperature, they are undesirably separated. Boards damaged in this way must be replaced with new ones. At the same time, the same actions cause bending and longitudinal twisting of the planks. These undesirable deformations do not occur with reinforced planks and the effect of climate change is therefore much less apparent with reinforced planks.

    REALIZATION EXAMPLES OF THE TECHNICAL SOLUTION
    Reinforced plank 1 is intended primarily for outdoor installation thanks to its reinforcement. The reinforced plank 1 according to the present example of the technical design according to Figures 1, 2, 9 to 13 consists of at least two longitudinal planks 2 made of natural hardwood. The hardness of the wood and its growth parameters in most cases do not allow to construct the planks from only one piece of wood and therefore for the length of a classic plank it is necessary to combine several pieces of shorter longitudinal planks 2 with identical cross-sectional parameters. These individual longitudinal planks 2 are connected to one another in the transverse direction by a joiner connection 3 . According to this example of the embodiment of the technical solution, such a joiner's joint is zinc joint 3, which is a combination of toothed joint and wood glue technology. In this example of embodiment of the technical solution, the reinforced floorboard 1 is provided on the underside 4 at least partially in its length 13 with at least one recess 5 having at least one pair of lower grooves 6 . In the recesses 5 in question a flat reinforcement 7 is housed, which is formed by a base plate 8 with at least two longitudinal projections 9 which fit into the lower grooves 6. The lower grooves 6 are arranged in the longitudinal direction of the reinforced board 1. FIG.
    According to an example of the embodiment of this invention, which relates to Figures 1, 2, 9 to 13, the longitudinal plank 2 is made of acacia wood.
    According to the example of the realized technical design, shown in Figure 1, the reinforced plank 1 is provided on its longitudinal sides 10 with at least one lateral groove 11. The side groove 11 serves to connect several reinforced floorboards 1, the mutual connection being achieved by inserting a side tongue simultaneously into two adjacent side grooves 11 of a pair of reinforced floorboards 1 arranged next to one another.
    According to the examples of technical implementation realized, shown in Figures 7 and 8, the flat reinforcement 7 is formed by a base plate 8 in the form of a thin prism. The longitudinal projections 9 are located on the base plate 8 at two opposite upper edges, the two longitudinal projections 9 being arranged parallel to one another.
    According to the examples of realized technical design, shown in Figures 3 to 6, the areal reinforcement 7 is formed by a base plate 8 in the form of a thin prism. At least three longitudinal projections 9 are arranged on the base plate 8 in such a way that two longitudinal projections 9 are located on two opposite upper edges of the base plate 8 and the remaining longitudinal projections 9 are at regular intervals on the upper side of the base plate 8 in the space between the two longitudinal projections 9 located at the edge are arranged. All of the longitudinal projections 9 are arranged parallel to one another on the base plate 8 . The distribution of the longitudinal projections 9 is ideally regular, so that the distribution of future loading forces from the longitudinal boards 2 remains as even as possible.
    The flat reinforcement 7 is preferably made of a light metal, e.g. B. aluminum, but can also be made of plastic, steel or another material known to those skilled in the art, which is characterized in particular by a high bending and torsional strength.
    According to a non-illustrated example of the technical embodiment realized, between the longitudinal plank 2 and the flat reinforcement 7 there is a layer of bonding adhesive. This layer of adhesive is applied to at least part of the mutual contact surfaces of the longitudinal board 2 and the surface reinforcement 7.
    The use of a joint adhesive is primarily intended to ensure the strength of the joint of the longitudinal plank 2 and the surface reinforcement 7 and at the same time to seal any gaps and joints between these joined parts of the reinforced plank 1.
    After the example of realized technical solution shown in images 1, 2, 10 to 13, the reinforced plank 1 is additionally provided with anchoring elements 15. In this example of the technical solution implemented, shown in Figures 3 to 8, the surface reinforcement 7 is also provided with continuous openings 14 through which the anchoring elements 15 run. This leads to a further stronger anchoring of the flat reinforcement 7 to the longitudinal board 2. The resulting connection can thus only be glued according to the previous example or screwed according to this example, or according to both examples combined. The anchoring element 15 is preferably a wood screw or other anchoring element 15 well known to those skilled in the art used to join materials, at least one of which materials is wood.
    According to the example of the technical solution implemented, shown in Figures 10 and 11, the flat reinforcement 7 covers at least part of the transverse width 12 of all the longitudinal planks 2 that form a whole reinforced plank 1. At the same time, the flat reinforcement 7 covers this width 12 over the entire length 13 of the reinforced floorboard 1 . There is thus an overall reinforcement of the reinforced plank 1, which primarily protects the reinforced plank 1 against bending and twisting, which occur in long wooden profiles in connection with changes in humidity and temperature. At the same time, all joiner connections 3 occurring on the reinforced floorboard 1 are also reinforced. These joiner joints 3 lose their original strength over time, due to the aging of the jointing materials and as a result of climatic variations that affect the expansion and contraction of the wood. At the same time, the use of the flat reinforcement 7 prevents the connections from coming loose and the individual longitudinal planks 2 from separating.
    After the example of realized technical solution shown in Figures 12 and 13, the flat reinforcement 7 covers at least part of the transverse width 12 of two adjacent longitudinal boards 2. At the same time, the flat reinforcement 7 covers at least part of the length 16 of these two adjacent and interconnected longitudinal boards 2 at the points of their mutual connection. The flat reinforcement 7 thus always covers at least part of the carpenter's connection 3, which connects the two longitudinal boards 2 to one another.
    INDUSTRIAL AVAILABILITY
    The reinforced board is used in the construction of buildings as a floor covering, especially for the exterior surfaces of houses, porches, outbuildings, pergolas and garden houses and bungalows. The execution of the reinforced plank guarantees not only a high-quality aesthetic impression resulting from the use of real wood with all its thermal and noise properties, but also a sufficient and significantly extended service life of the planks used in an unstable climatic environment.
