DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for jointing a top plate of a counter or the like, in which edge members 2, 2 made of synthetic resin are attached to opposite end surfaces of a pair of wooden substrates 1, 1, respectively. A top plate material 11 is formed in which the top surface of the top plate material 2 and the top surface of the end surface material 2 are flush with each other, and the surface material 3 is pasted on the top surface of the top plate material 11 except for the edges, and the bottom surface of the opposite end of each substrate 1 is affixed to the top surface of the top plate material 11. Install the joint fittings 4, 4,

Wooden substrate such as plywood or particle board 1
Conventionally, when connecting the top plate A of a counter etc. formed by pasting the surface material 3 on the top surface of the
As shown in Figures a and b, joint fittings 4, 4 attached to the lower surfaces of the opposing ends of each board 1, 1 are connected with bolts and nuts 5 to butt the end surfaces of the boards 1, 1 against each other. . However, in this case, water infiltrates into the edge of the wooden substrate 1 from the butt part of the substrates 1 and 1, causing the edge of the substrate 1 to swell, and the surface material 3 to be pushed up as shown in FIG. 1b. I was afraid. Therefore, in order to prevent such water from entering, it is necessary to apply adhesive or sealant 6 to the end surface of the substrate 1 during construction, which creates a problem that the construction is troublesome. As the substrate deteriorated, the water sealing effect also decreased, and the effect of preventing swelling of the end portion of the substrate 1 was not sufficient.

The present invention has been made in view of the above points, and can prevent water from entering the board from the joint portion and swelling the end of the board without using adhesives or sealants. To provide a method for jointing a top plate of a counter, etc., which can prevent the occurrence of conspicuous unevenness in parts.

The present invention will be explained in detail below with reference to Examples. The substrate 1 is made of a wooden material such as plywood or particle board, and the edge material 2 made of a waterproof synthetic resin material such as polyvinyl chloride or polyethylene is attached to the end surface of the substrate 1 by adhesive or the like. The top plate material 11 is formed by holding the top plate material 11. Further, a surface material 3 made of a melamine decorative board or the like is adhered to the upper surface of the substrate 1 portion of the top plate material 11. A top plate A such as a counter is constituted by a substrate 1, an end surface material 2, and a surface material 3, and an inverted L-shaped joint fitting 4 is fixed to the lower surface of the end of the substrate 1.

However, when jointing the pair of top plates A, A formed as shown in FIG. 2a in this way, each joint fitting 4, 4 is
The joint fittings 4, 4 are joined by passing the bolt/nut 5 through the through hole 7 and tightening, and the joint fittings 4, 4 are joined by abutting the end materials 2, 2 against each other. In this product, the end surfaces of the substrates 1, 1 are covered with synthetic resin end materials 2, 2, so even if water gets into the joint part, there is no risk of the water penetrating into the wooden substrate 1. be.

Here, as shown in FIG. 2a, the edges of the surface material 3 are cut out so that the surface material 3 is not pasted to the ends of the top plate material 11, and the portions where the surface material 3 is not pasted are cut out. Apply adhesive 9 to the stepped surface 8 created by this notch on the upper surface of the substrate 1 or end material 2, and after jointing the top plates A and A together with the joint fittings 4, 4, attach the surface material 3. A joint surface material 10 made of the same material as shown in FIG. With this product, even if a difference in level is created between the upper surfaces of the end materials 2 and 2 when jointing as shown in Fig. 3, this difference in level is covered with the joint surface material 10, so that the difference in level can be prevented from becoming noticeable. .

In the above embodiment, it is of course possible to apply adhesive 9 to the abutting surfaces of the respective end panels 2, 2 to firmly join the top plates A, A.

As described above, according to the present invention, the end face of the wooden board is covered with the synthetic resin end face material, so even if water gets into the joint part of the top plate, the water will not enter into the board. Therefore, it is possible to prevent the substrate from swelling with water and to reliably prevent the surface material on the surface of the substrate from being pushed up by the swelling of the substrate without using a sealant or the like. In addition, a joint metal fitting is attached to the lower surface of the opposite end of each board, and the pair of end pieces are butted against each other, and both joint fittings are connected with bolts and nuts, so that the joint of both boards is done through the end piece. This is done with a joint metal fitting attached to the board instead of a joint, and stress for the joint is not applied to the end face material, and there is no need to firmly attach the end face material to the end face of the board. Even if the edge material is attached to the substrate by a simple means such as adhesive bonding, the strength of the joint between the substrates will not be affected in any way. In addition, the surface material is pasted on the top surface of the top plate material, excluding the edges, which is formed by attaching the end surface material to the opposite end of the board, and the surface material is attached between the surface materials pasted on the top surface of each top plate material. Since the joint surface material is pasted across the top surfaces of the butt ends, even if there is a difference in level between the top surfaces of the butt parts of the end materials when jointing, this difference in step will be covered by the joint surface material. This can prevent the difference in level from becoming noticeable.
