Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for joining a plurality of top plates when forming a long top plate of furniture such as a sink or a washstand using a plurality of top plates.

In general, the interior design of furniture such as sinks and washstands is important, so today, single, seamless top plates are often used to construct them. However, while a single top plate has no seams and is excellent for interior decoration, it is extremely difficult to transport into a living room during installation because it is long. In order to eliminate this difficulty in carrying in the house, it is conceivable to independently form a plurality of relatively short top plates, and then combine them within the living room after carrying them in. If you use this method,
The joints (joints) between each top plate must not be so conspicuous that they impair the interior design, and must not allow water to seep into the bottom of the top plate. It won't happen.

A common method for meeting such requirements is the use of adhesives. That is, FIG. 5 shows the method, in which a plurality of top plates 2a and 2b are opposed to each other with a gap T between them, with the packing 1 interposed therebetween.
After applying masking tape 3 to the upper surface of both sides, uncured adhesive 5 is injected into the gap T using a tube 4 or the like, and when the adhesive 5 has hardened to some extent (semi-hardened), the masking tape 3 is peeled off. Thereafter, the layer of adhesive 5 that protrudes above the upper surface level L of the top plates 2a, 2b is finished by cutting with a cutting tool 6 such as sound paper.

According to the method, the surface of the adhesive 5 is attached to both top plates 2.
Since it is substantially flush with the upper surface level L of a and 2b, and the gap T is completely sealed by the adhesive 5, the joint portion is less noticeable and watertightness is ensured. However, even with such an excellent method, if the masking tape 3 is not removed properly, the bonded portion will become noticeable. That is, as shown in FIG. 6, when the masking tape 3 is peeled off, a part of the adhesive 5 is also removed, and the upper surface level L of the top plates 2a and 2b is removed.
A recessed portion 5b is created which makes the joint more conspicuous.

As a result of various studies on the causes of this, it was found that there was a problem in the setting position of the masking tape 3, in addition to the sudden peeling off of the masking tape 3. In other words, the commonly used setting position of the masking tape 3 is a place where the end surfaces of the masking tape 3 are flush with the upper corners A of both top plates 2a and 2b, and where the masking tape 3 and the cutout 5b are formed. are too close to each other, and when the masking tape 3 is removed, part of the adhesive 5 is pulled by it, creating a cutout 5b.

Furthermore, the upper corner A of the top plates 2a, 2b is not necessarily straight, and a chip B is often formed due to cutting, etc., as shown in FIG. Since the adhesive 5 that has flowed in comes into contact with the masking tape 3, the generation of the cutout portion 5b becomes larger when the masking tape 3 is peeled off. FIG. 8 shows a view of the joined portion formed by the conventional joining method as viewed from above the top plates 2a and 2b, but it is unsightly due to the presence of the chip B and the cutout portion 5b.

The present invention is a joining method that reduces the conspicuousness of the joined portion of the top plates 2a and 2b by preventing the occurrence of the cutout portion 5b. First, as shown in FIG. A masking tape 3 is provided on the upper surface portions of the top plates 2a and 2b slightly spaced apart from the upper corner A of 2b. At this time, the upper corner A of the top plate 2a is chipped B
If there is a masking tape 3, the masking tape 3 is provided a little further away from the masking tape 3. Next, the adhesive 5 is injected into the gap T and the spaced part H of the masking tape 3 using a tube 4 or the like and is cured (semi-cured).
The layer C of the adhesive 5 that is separated from the upper surface of the top plate 2b and that protrudes from the upper surface level L of the top plates 2a and 2b is finished by cutting with a cutting tool 6 such as sound paper.

In the above case, since the masking tape 3 is slightly apart from the adhesive 5 in the gap T or the chip B, the adhesive 5 is peeled off when the masking tape 3 is removed, as shown in FIG. It stays on the surface part of 5. Therefore, since the cutout portion 5b does not occur below the upper surface level L of the top plates 2a, 2b as in the conventional case, the joint portion is less conspicuous as shown in FIG.

As described above, according to the method of the present invention, the top plates can be joined while reducing the conspicuousness of the joint portion of the top boards.
