Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for jointing top plates of counters, etc., in which a waterproof tape 2 is pasted to the lower part of at least one of the opposing end surfaces of a pair of top plates 1, 1, and an adhesive 3 is applied to the upper part. and attach joint tools 4, 4 to the lower surfaces of the opposite ends of each top plate 1, 1,
By joining both joint tools 4, 4 with bolts and nuts 5, the waterproof tape 2 and the end surface of the other top plate 1 are brought into pressure contact, and the adhesive 3 is applied to both top plates 1,
A specific invention for a method for jointing a top plate of a counter, etc., characterized in that the adhesive 3 is filled between the end surfaces of the top plates 1 and 1, and the adhesive 3 protruding above the end surfaces of the top plates 1 and 1 is removed, and then the adhesive 3 is cured. Then, a waterproof tape 2 is pasted on the lower part of at least one of the opposite end surfaces of the pair of top plates 1, 1, and an adhesive 3 is applied to the upper part, and a joint tool is attached to the lower surface of the opposite end of each top plate 1, 1. 4, 4 are attached, a protruding piece 6 is provided protruding from the lower end of the opposing surface of at least one of the joint tools 4, and bolts and nuts 13, 14 are inserted into both joint tools 4, 4 above the protruding piece 6. By press-fitting both joint tools 4, 4, the waterproof tape 2 and the end face of the other top plate 1 are brought into pressure contact, and the adhesive 3 is filled between the end faces of both the top plates 1, 1. The combined invention is a method for jointing a top plate of a counter, etc., which is characterized in that the adhesive 3 protruding above between the end surfaces of the first and second parts is removed and then the adhesive 3 is cured.

When jointing the top plates 1, 1 of a counter, etc., conventionally, as shown in FIG. The end surfaces of the top plates 1, 1 were butted against each other by joining with bolts and nuts 5. However, in this product, adhesive is applied between the end surfaces of the top plates 1 and 1 to prevent water from penetrating below the abutting surfaces of the top plates 1 and 1, but adhesive 3 alone does not have a water sealing effect. It is weak, and there is also a risk that the adhesive 3 between the end surfaces of the top plates 1 and 1 will be pushed downward when the top plates 1 and 1 are butted together during joint construction, and the adhesive 3 will spill out and stain the floor. It was hot. Furthermore, in such a conventional example, the force for jointing the top plates 1, 1 is obtained by the bolt/nut 5 that tightens the joint tool 4 on the lower surface of the top plates 1, 1; Since it worked below the top plate 1, there was a fear that a gap would be created between the end faces of the top plates 1, 1.

The present invention has been made in view of the above points, and has the primary purpose of providing excellent water sealing properties at the abutting surfaces of the top plates and preventing the adhesive from spilling out. The second purpose is to prevent gaps from forming between the holes.

The top plate 1 has a surface material 8 such as a melamine decorative board on the top surface of a wooden substrate 7 such as plywood or particle board.
A substantially inverted L-shaped joint tool 4 is attached to the bottom surface of the end of the top plate 1.

Therefore, when jointing the pair of top plates 1 and 1 as described above, first, as shown in FIG. Nitto Denko
Co., Ltd.) over the entire width, and putty-like epoxy, urethane, polyester, or
Apply acrylic hardening adhesive 3. At this time, it is preferable to apply masking tape 9 to the upper surfaces of the ends of each top plate 1, 1. Next, as shown in FIG. 2b, the end face of the other top plate 1 is brought into pressure contact with the waterproof tape 2 by passing the bolts and nuts 5 through the through holes 10, 10 of the joint tools 4, 4 and tightening them. Then, the adhesive 3 is compressed between the end faces of the top plates 1, 1, and the space between the end faces of the top plates 1, 1 is filled with the adhesive 3, and the excess adhesive 3 protrudes upward. Because of the waterproof tape 2, the adhesive 3 does not protrude downward. Next, wipe off the adhesive 3 that has protruded upward, remove the masking tape 9, and after the adhesive 3 has hardened, sand the surface of the adhesive 3 to make it flush with the top surface of the top plate 1. Finish.

The one in FIG. 3 shows a plywood joint tool 4 attached to the bottom surface of a top plate 1 made of marble or the like, and a protruding piece 6 is provided at the bottom of one joint tool 4. In this device, the joint tool 4 is attached to the top plate 1 so that the tip end face of the protrusion piece 6 is located in the same vertical plane as the end face of the top plate 1, and the formation of the protrusion piece 6 allows the joint tool 4 to be placed on the upper side of the protrusion piece 6. A recessed step portion 11 is formed in the joint tool 4. Further, a mounting recessed part 12 notched to the same level as the recessed step part 11 is formed in the top plate 1, and a waterproof tape 2 is attached to the mounting recessed part 12. The through hole 10 is formed in the recessed step portion 11, and an embedded nut 13 is attached to the through hole 10 on the side provided with the protruding piece 6. However, when joining the top plate 1 of the lever, as shown in Fig. 3b, the bolts 14 and circular through holes 10,
When the joint tools 4, 4 are tightened and connected by screwing the bolt 14 into the nut 13 through the bolt 10, the bolts and nuts 13, 14 are positioned above the protruding piece 6, so that the top plate is attached to the top plate using the protruding piece 6 as a fulcrum. A moment M acts to press the end surfaces of the top plates 1 and 1 together, and by tightening the bolts and nuts 13 and 14, the joint can be performed without creating a gap between the end surfaces of the top plates 1 and 1. The adhesive 3 that has protruded onto the top plate 1 is removed in the same manner as in FIG. 2, and the finished product is finished as shown in FIG. 3c.

As described above, in the present invention, in addition to the adhesive, a waterproof sheet is interposed between the end faces of the top plate, so it is possible to obtain a double water-sealing effect of the adhesive and the waterproof sheet, and the ceiling It is possible to improve the waterproofness of the joint part of the board, and when the ends of the top board are butted together, the waterproof sheet prevents the adhesive from spilling out below the top board, causing the adhesive to drip and spill onto the floor. There is no risk of contaminating the In addition, in the combined invention of the present invention, a protruding piece is provided protrudingly at the lower end of the opposing surface of one joint tool,
Since a pair of joint tools are press-fitted with bolts and nuts above the protruding piece, tightening of the bolt and nut creates a moment that presses the end faces of the top plate with the protruding piece as the intersection point, without creating a gap. This allows the end surfaces of the top plate to be joined together.
