DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for jointing a top plate of a counter, etc.
The surface materials 2, 2 are pasted so as to protrude from the end surfaces of the surface materials 2, 2, and the surfaces of the surface materials 2, 2 are attached so that the protruding end surfaces of the pair of surface materials 2, 2 are butted flush with each other so as to straddle both surface materials 2, 2. After applying masking tape 3 to
The present invention relates to a jointing method for a top plate such as a counter, which is characterized in that adhesive 4 is filled in the gap between the end faces of paper sheets 1 and cured, and then masking tape 3 is peeled off.

When jointing the top plates A, A of a counter, etc., conventionally, the joint tools 5, 5 are attached to the lower surfaces of opposite ends of each top plate A, A, as shown in Fig. 1 a, b. The end surfaces of the top plates A and A were butted against each other by joining with bolts and nuts 6. However, in this case, if the machining precision of the joint tools 5, 5 is poor, unevenness is likely to occur on the surfaces of the joint ends of the top plates 1, 1, as shown in FIG. 1b. In addition, water infiltrated into the edge of the wooden substrate 1 from the abutted portion of the top plates A, A, causing the edge of the substrate 1 to swell and the edge of the surface material 2 to be pushed up. Therefore, in order to prevent such water from entering, it is necessary to apply an adhesive or sealant 7 to the end surface of the substrate 1 during construction, but simply applying the adhesive or sealant 7 is insufficiently effective. It was hot.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a method for joining a top plate of a counter, etc., which allows the top plate to be joined without fear of unevenness and which has an excellent waterproof effect. It is.

The present invention will be explained in detail below with reference to Examples.

Top plate A has a surface material 2 such as melamine decorative board on top of a wooden substrate 1 such as plywood or particle board.
In this case, as shown in FIG. 2A, the surface material 2 is pasted so that its end portion protrudes from the end surface of the substrate 1 over a predetermined length and width. Next, as shown in Fig. 2b, the protruding end surfaces of the facing materials 2, 2 of the pair of top plates A, A are butted against each other so that the upper surfaces are flush with each other, and between the end surfaces of each facing material 2, 2. Masking tape 3 is pasted to connect both surface materials 2, 2. This work is done on each top plate A,
It is best to do this with it upside down. Next, with each top plate A, A turned over, place both top plates A, A on a flat fixed plate, etc., and leave the gap between the end surfaces of the boards 1, 1 as shown in Figure 2 c. A curable adhesive 4 such as epoxy, urethane, or acrylic adhesive is filled in and cured. In this way, the pair of substrates 1, 1 and the pair of surface materials 2, 2 are bonded together using the adhesive 4, and the pair of top plates 1, 1 is jointed. Finish the joint as shown in d. At this time, since the adhesive 4 to be filled is adhered to the end surface of the substrate 1 and the back surface of the end of the surface material 2, the surface material 2 is bonded to the substrate 1 via the adhesive 4. This can firmly prevent the surface material 2 from peeling off from the substrate 1.

As described above, in the present invention, the surface material is pasted so that the end portion protrudes from the end surface of the substrate, the protruding end surfaces of the surface material are brought flush against each other, and the gap between the end surfaces of the substrate is filled with an adhesive. Because of this, it is possible to join the top plate with the surface flush without the risk of unevenness as would be the case when using a joint tool, and what is more, the adhesive is filled into the gap between the edges of the board instead of simply being applied. This makes it possible to improve the waterproofness of the joint part of the top plate.

Claims (1)

[Claims] 1. Paste a surface material on the upper surface of a pair of substrates so that the end protrudes from the end surface of the substrate, and then attach the surface material to the surface of the surface material so that the protruding end surfaces of the pair of surface materials are flush with each other and straddle both surface materials. A method for jointing a top plate such as a counter, which is characterized by pasting masking tape, filling the gap between the end faces of both boards with an adhesive while turning the boards inside out, and curing the adhesive, and then peeling off the masking tape. .
