DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building board for forming floors and walls of a building.

[0002]

2. Description of the Related Art Conventionally, building plates have been made by joining a plurality of plate materials 1 together. The plate member 1 is a rectangular wooden plate or the like, and has a cutout 5 having an L-shaped cross section that opens on one surface on a longitudinal side surface as shown in FIG.
The notch 5 of the other plate 1 is made to face the notch 5 of the plate 1, and the notch 5 adjacent to the plate 1, and facing the notch 5,
5 is a concave groove 2, and an adhesive 3 of a hot melt and a urethane resin is filled in the concave groove 2 and hardened, whereby a building board is prepared.

[0003]

However, if the plate material 1 is twisted or warped (especially warped width), a step or a knuckle (gap) occurs at the joint. Then, for a long time until the adhesive hardens, pressure is continuously applied to the building board from outside, and the board 1
It was necessary to correct twisting and warping to eliminate unevenness and hagiski.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to provide a building board capable of eliminating unevenness and hagisuki without long-time external correction.

[0005]

According to the present invention, there is provided a building board comprising:
Cutouts 5 are formed on the side of the plate 1 and open on the back surface, and the side of the other plate 1 is formed on the side of the plate 1 by the cutouts of the respective plates 1, 1.
5,5 Cormorant along the side surface of the plate 1 at this junction with each other are opposed to the adjacent by matching with grooves 2
Are formed by the opposed notches 5 and 5 , and the adhesive 3 is filled and hardened in the concave groove 2, and the two plate materials 1,
1 is provided with a coupling tool 4 for coupling the two.

[0006]

Since the adhesive 3 is filled and hardened in the groove 2 and the connecting member 4 for connecting the two plate members 1 and 1 is provided across the groove 2, the connecting member 4 is provided until the adhesive 3 is hardened. 4 can correct the twist and warpage of the plate 1.

[0007]

The present invention will be described below in detail with reference to examples. The coupling tool 4 is formed as a staple having a U-shaped cross section using a plastic molded product or a metal such as iron or aluminum. Although this connecting tool 4 is for connecting the plate 1, it may be cut at the time of processing or construction after the connecting, and in consideration of this, a plastic molded product is more convenient.

The plate member 1 is a rectangular wooden plate or the like, and has a cutout 5 having an L-shaped cross section which is open on the back surface on one longitudinal side surface. The notch 5 of another plate 1 is inserted into the notch 5 of this plate 1.
The recesses 2 are formed by the notches 5, 5, which are adjacent to the plate materials 1, 1, and which face each other. The concave groove 2 is filled with an adhesive 3 of a hot melt and a urethane resin, and the adhesive 3 is hardened so that the adjacent plate members 1 and 1 straddle over the concave groove 2 while correcting the twist and warp. The joining tool 4 is driven into the vicinity of the end of the back surface of the plate materials 1 and 1 so that the plate materials 1 and 1 are joined. Alternatively, the bonding tool 4 may be driven first, and then the groove 3 may be filled with the adhesive 3. And adhesive 3
The building board as shown in FIG. 1 is formed by curing. The number of the couplings 4 is appropriately determined according to the length of the plate 1 and the strength of the building board .

In this building board, since the connecting members 4 are driven into the surfaces of the board members 1 and 1 while correcting the twist and warp of the board members 1 and 1, the board members 1 and 1 are joined together. There is no need to correct the twist and warp of the plate materials 1 and 1 by continuously applying pressure or the like. FIG. 2 shows another embodiment. This plate 1 is provided with a notch 5 having an L-shaped cross section that opens on the back side on both longitudinal side surfaces, and the other plate 1 is adjacent to the plate 1 while being slightly shifted in the longitudinal direction, and the notches 5 and 5 are opposed to each other. The connection is made in the same manner as in the embodiment.

[0010]

As described above, according to the present invention, the side and the back are added to the plate material.
A notch that opens to the surface is formed, and the side of another plate is joined to the side of the plate with the notches of each plate facing each other.
The coupler which is formed by the cutout portion facing the along cormorants grooves on the sides of the plate at the joint with the adjacent couples both plate members across the groove to fill cure the adhesive in the groove by the Because of the provision, the torsion and warpage of the plate material can be corrected by the coupling tool until the adhesive is hardened, and unevenness and hagisuki can be eliminated without correction from outside for a long time. Also, adhesive on the recess
After filling, not only the joint is provided, but also the joint
Adhesive can be filled after the beam is applied.
Adhesive can be filled while fixing each other
And bonding in a state where the plate materials are butted against each other
The filling work of the agent is easy. Furthermore, after joining the plate
The joint between the plate materials is softened by cutting the joint
It can be soft and the building board is placed on the base material
Can absorb the unevenness of the base material when
You.
