Description

[Detailed explanation of the invention] (Industrial application field) This invention relates to construction materials used for flooring, walling, etc.

(Prior art and its problems) Conventionally, raw wood, boards made by sawing square timber lengthwise, pieces of wood cut into small pieces, cross plywood, etc. have been used as flooring and wall materials. Sawn planks lack durability due to cracks, etc., and due to the rising cost of lumber, single solid planks are rarely used, and wood pieces cut into small pieces from raw wood are difficult to dry. This is extremely inconvenient, and also has the disadvantage that radial cracking occurs due to drying, making it unsatisfactory not only in terms of appearance but also in terms of durability.
Furthermore, in the case of cross plywood, there are disadvantages in that it is inferior in durability, such as the adhesive part peeling off.

(Means for solving the problem) This project was researched to solve the above-mentioned drawbacks, and by fitting pieces of wood cut into small pieces in the direction of alignment of parallel plywood into the recesses of the base plate, durability can be improved. Of course, there were no cracks or distortions, and even if the adhesive part of the plywood peeled off, it was found that it could still function as a floor and wall.

The present invention will be described in detail with reference to the illustrated embodiment. The edge surface 4 of a piece of wood 3 made by cutting parallel plywood 1 into small pieces in the direction in which the veneers 2, 2'... It is fitted through the holder. The shape and number of the recesses 6 are determined by the size of the adjacent fitting base plate 5.
The rising walls 8 between the recesses 6 serve as joint fillers after construction.

The parallel plywood 1 is made by bonding veneers 2, 2'... with the grains aligned in a certain direction.

Also, the size, shape, etc. of the piece of wood 3 are cut to match the recess.

(Function) The present invention is realized as described above, and to use it, the floor of the construction site is leveled, and adhesive is sequentially applied while bonding and assembling the bottom surface of the fitting base plate 5.

(Effects) As mentioned above, in this case, parallel plywood is cut into pieces in the direction in which the veneers are joined, and the edges of the pieces of wood are fitted into the recesses of the base plate with adhesive, so the veneers that form the parallel plywood Even if mutual adhesion breaks down, the rising walls of the recess will restrict the spread. Therefore, the pieces of wood are not broken into pieces because they are not divided into pieces.

Also, since the cut ends of the wood grain are exposed on the surface, it has excellent abrasion resistance even when it comes into contact with shoes, etc. Furthermore, since thin veneer-like pieces are dried and bonded together during manufacturing, the drying process is sufficient in a short time, and since sufficient drying is possible, there is little expansion and contraction, and construction accuracy is high.
