Abstract

PURPOSE:To eliminate the gear of introducing a fire, to prevent an end from deforming and to improve operating efficiency by forming a recess opened at one face side of a wooden base plate near the cut end of the base plate, and filling synthetic resin having water resistance in the recess to couple it to the base plate. CONSTITUTION:Rectangular sectional grooves 2B are formed along cut ends 2A near the cut ends 2A of both ends of a base plate 1 made, for example, of a particle board or a laminated plywood are so opened as to open at both ends on one side of the base plate 2. The bottom 2C of the groove 2B is disposed near the other end face 2D of the base plate 2. A rodlike filler 3 of synthetic resin having water resistance and preformed is buried in the groove 2B, and bonded by synthetic resin adhesive 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plate material suitable for use as a top plate for kitchen furniture, bathroom furniture, etc., and as a building material such as wall material and flooring material.

[Conventional technology and problems]

When a board is used as a top plate for kitchen furniture, for example, and when the top board is in contact with a wall on three sides, the left and right side edges of the board are usually slightly cut to the desired width, and the cut portions are After applying waterproof resin to the surface, it is dried and then
I am trying to place it in a cabinet. According to this method, it takes time and effort to treat the side edges of the board at the installation site, and there is a risk of fire because a solvent is used when applying the resin. . In addition, when a board is pasted on the floor of a kitchen, for example, from the center of the floor to the vicinity of the wall, most of the moisture on the floor is removed by cleaning, and the surface of the board is waterproof. In some cases, flooring boards have been treated to absorb water and will not cause phenomena such as deformation or corrosion. Due to poor circulation, there is a problem in that water is often absorbed from the butt end of the end of the board, which is located at the boundary, and this part becomes wet, deforming and corroding.

[Means for solving problems]

The present invention has been made to solve the above-mentioned problems, and therefore, according to the present invention, four parts are formed in the vicinity of at least one end end of a wooden board, and are open to one side of the board. , the recess is filled with a water-resistant synthetic resin and bonded to the substrate.

〔Example〕

1 to 6 show an embodiment of the plate material according to the present invention.

In FIGS. 1 to 3, reference numeral 1 indicates a wooden board 2.
This is a plate material in which synthetic resin filler 3 is bonded to both ends of the plate. To be more specific, the substrate 2 is made of, for example, particle board or laminated plywood, and grooves 2B having a rectangular cross section along the edges 2A are formed near each edge 2A on both sides of the substrate 2 and open on one side of the substrate 2. It is perforated to do so. Groove 2
The bottom portion 2C of B is close to the other surface 2D of the substrate 2. A pre-formed rod-shaped filling material 3 made of water-resistant synthetic resin is embedded in this groove 2B, and a synthetic resin adhesive 4 is embedded in the groove 2B.
It is coupled to the substrate 2 by.

The adhesive 4 used is one that has water resistance after curing,
It may be poured into the groove 2B or applied.

A water-resistant facing sheet, such as a melamine decorative sheet 5, is attached to one surface 2D of the substrate 2. Also,
One end 2E of the end of the board 2 perpendicular to the main end 2A
A butt end sealing edge 6 made of water-resistant synthetic resin is attached. This end sealing edge 6 is formed by, for example, filling a space between the end 2E and a mold attached to the end 2E with a liquid synthetic resin by pressurized injection, and allowing the resin to adhere to the end 2E and harden.

For example, as shown in FIG. 4, this plate l has three walls 7
, 8. Kitchen furniture cabinet IO installed near 9
It can be placed and used as a top plate. In this case, the front end of the board 2 in the figure, that is, the end 2F on the opposite side to the end where the main end sealing edge 6 is attached, is shown in FIG. As shown in FIG. 1), the frame 12 is attached in advance with a water-resistant synthetic resin layer 11 interposed therebetween. Also, the plate 1 is stored in contact with the left and right walls 7°9, so the plate 1 is shown by the chain line in Fig. 2 so as to match the distance between the left and right walls 7 and 9. The filler material 3 is cut in the front-rear direction as shown in FIG. Next, the board 1 is placed upside down from the state shown in FIGS. 1 to 3 on the cabinet IO, and the sink 14, range 15, etc. are attached as necessary. In this way, as shown in FIG. 6, the cuts 3A of the filler 3 are exposed to the left and right walls 7 and 9, and the water splashed on the plate 1 is exposed to the left and right side edges. Even if water flows in, the filling material 3 prevents water from being absorbed.

In this case, even if some of the wood remaining between the filler 3 and the melamine decorative sheet 5 absorbs water, there is no practical problem. In addition,
At the rear end of the plate l, the end sealing edge 6 allows
Further, it goes without saying that at the front end, the synthetic resin layer 11 similarly prevents water absorption into the plate material 1, and thus prevents deformation of the plate material 1. According to such a construction method, waterproofing can be easily and quickly carried out at the side edges of the board 1 serving as a top plate without any special work at the construction site. No need to use flammable resin for processing.

In another embodiment of the invention shown in FIG.

The plate material 17 has the above-described melamine decorative sheet 5 pasted on one side of the base material 2 in advance.

Groove 2G reaching the melamine decorative sheet 5 at the side end of the substrate 2
, and apply adhesive 4 in 12G as in the first example.
It has a structure in which a water-resistant synthetic resin filler 18 is bonded to the substrate 2 via.

According to this embodiment, since there is no wood between the filler 18 and the melamine decorative sheet 5, when the filler 18 is cut at the required position indicated by the chain line, the cut surface and the melamine decorative sheet 5 is exposed, making it more waterproof than the first embodiment.

In addition to the above-mentioned embodiments of the present invention, the filler does not necessarily need to be bonded to the vicinity of two or more edges of the substrate, but may be bonded only to the vicinity of one edge depending on the intended use of the board. Of course, this is also possible. In addition, as a filler, after the adhesive in the groove drilled in the substrate dries, a mold is attached to the groove, a synthetic resin that has good bonding properties with the adhesive is injected under pressure, and then dried. It may be formed by hardening. In addition, when the plate material according to the present invention is used as a wall material or a floor material, the filler part is cut to match the dimensions of the installation location as described above, and the plate material according to the present invention is cut between the ceiling and the floor, or between the floor and the wall. They may be located at each boundary between the two.

〔Effect of the invention〕

According to the present invention, by cutting and exposing the water-resistant synthetic resin filler provided in advance at the end of the board, there is no need to waterproof the end of the board at the construction site.
Not only does it significantly increase work efficiency, it is advantageous in terms of safety since there is no risk of causing a fire, and the waterproofing effect of the filling material prevents deformation of the edges and extends the lifespan of the board after installation. It is effective.
