[Industrial applications]

 The present invention relates to a flooring block upholstery plate for laying square wooden boards in a checkerboard pattern on a concrete floor surface of a building to finish the board floor.

[0002]

[Prior Art]

 The flooring block upholstery plate that has been used in the past is a square plate (a) made by laminating several pieces of short wood with a thickness of about 10 as shown in Fig. 4 in the form of a joint and tongue and groove. ) Is attached to the back side of () to finish it into a block shape of about 30 mm square. A large number of this plate is used for each foot (B) (B). It is practiced to embed and fix it in mortar that has flowed onto the concrete floor and lay it in a checkered pattern.

[0003]

[Problems to be solved by the device]

 In this case, since the above-mentioned conventional flooring block board is mortared directly onto the concrete floor surface, the backside of the square board (a), which is an aggregate of short-cut wood pieces, is used for the installation. In each case, it is necessary to apply a waterproofing agent to prevent the wood board from absorbing moisture due to contact with the mortar, and this application is usually done while the construction is in progress. However, applying the waterproofing agent each time is time-consuming, and the board with the waterproofing agent applied is inconvenient to handle. Therefore, there was a problem that a piece of wood that was originally susceptible to moisture absorption warped due to the water content of the mortar.

[0004]

[Means for Solving the Problems]

 On the other hand, the flooring block upholstery plate of the present invention is a square plate made by sticking together a few short strips of wood. It is formed by laminating pressed synthetic plates, generally called particle boards, into a single thick plate material.Because the particle board is hard and does not cause cracks, warps, etc. However, the construction does not require the application of waterproofing agents.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the whole is made up of several pieces of short wooden pieces, and the wood grain is cut in advance from the bottom to prevent warping. A large number of cut grooves 1a extending along the upper surface and a large number of cut grooves 1b orthogonal to the grain are attached to the lower surface of a square face plate 1 with an interval of about 3 wear between the upper surface and a small piece of wood. A reinforcing board 2 made by cutting a particle board pressed into a plate shape by mixing a binder to the square board 1 is bonded to the square board 1 via an adhesive layer 3a, and is further isosized on the lower surface thereof. The thin wooden boards 4 are bonded to each other via the adhesive layer 3b to form an integrated thick board 5, and the mounting holes 6 are arranged at predetermined positions of the four corners of the board 5. . In this case, as the adhesive layers 3a and 3b, water-based adhesives that are usually used may warp due to water before drying. Therefore, polyurethane adhesives, epoxy resin adhesives, and reactive acrylics may be used. An oil-based adhesive such as a system adhesive or an unsaturated polyester adhesive is used.

[Action and effect]

 The present invention has the above-mentioned structure, and a large number of the plate members 5 ... Are laid side by side on the appropriate pillow member 6 fixed on the concrete floor surface with the reinforcing plate 2 as the lower surface, and the mounting holes 6 ... By previously fitting and fixing to a mounting rod or the like provided upright on the pillow member 7, a series of flooring block-tensioned floor surfaces can be formed. 2, the pillow members 7 ... As shown in FIG. 3, four mesin cylinders 7c are provided on the upper surface of the inverted container-shaped member 7b whose lower edge is a mounting edge 7a against the concrete floor surface in advance. ... are erected and screw rods 7e having a receiving plate 7d in the middle are screwed into the female screw cylinders 7c, and the corners of the plate members 5 are mounted on the receiving plates 7d of the screw rods 7e. A type is shown in which it is supported and fixed through holes 6, ... In this case, the plate member 5 is placed on the receiving plate 7d, and then the screw holes 7e are screwed into the driver engaging holes provided on the top surface of each screw rod 7e. By engaging and rotating to adjust the height of the receiving plates 7d, the corners of the surface plates 1 can be accurately aligned on the same plane. The pillow member 7 does not necessarily have to be provided on the concrete floor surface, and may be fixed to the lower surface of the plate material 5 with wood screws or the like as in the conventional one shown in FIG. 4. In this case, the mounting hole 6 is unnecessary. Become.

As described above, the present invention makes it easy to create a beautiful floor by laying out a large number of surface plates 1 made by sticking short wooden pieces as an upper surface through the respective mounting holes 6 ... Although it is possible to finish the surface, it is efficient and the hard reinforcing plate 2 is attached to the construction because it does not require the work such as applying the waterproofing agent to the lower surface of the reinforcing plate 2 as described above. Since they are joined together, the strength of the whole plate member 6 is extremely high. Moreover, since the surface plate 1 has a large number of warp preventing cut grooves 1a ... 1b ... The warp that tends to occur in the reinforcing plate 2 without causing the deviation is further reliably prevented because the upper and lower surfaces of the reinforcing plate 2 are sandwiched by the surface plate 1 and the wooden board 4. Further, with this configuration, the plate member 5 has excellent sound insulation and is suitable as a soundproof floor material.
