Description

[Detailed Description of the Invention] [Industrial Application Field] Conventionally, the processing method for attaching a decorative top plate and a tank-like object (hereinafter simply referred to as a "tank") is to create an adhesive between the decorative top plate and the tank. Either fix it by hardening it with a synthetic resin layer, or process the side of the opening (hole) with resin during or after creating the decorative top plate, and then use cutting to create a seat for attaching the tank flange. After the tank is attached with a fitting, it is common to further strengthen the tank with synthetic resin for waterproofing and mechanical strength.

These are all connected to the substrate 2 as shown in Figures 3 to 5.
Resin 3, which is absolutely necessary for construction, appears on the surface between the decorative board 1 and the tank 4 (3' is the resin exposed part), and in actual production, the distance between the decorative board and the tank is about 4 m/m. ends up leaving.

Considering the function and design of the decorative top plate having a tank, it is natural that the decorative board 1 and the tank 4 should be adjacent to each other without exposing the resin 3 3'. and tank 4 are combined,
The reality is that sinks and washstands that can withstand severe usage conditions cannot be obtained.

In view of this situation, the present invention provides a processing method with excellent functionality and design in an undersink method in which the lower surface of the decorative panel on the decorative top plate and the tank are directly bonded.

That is, as shown in Fig. 1, a triangular space 10 is provided between the decorative board 1 and the substrate 2, and by utilizing the fact that the decorative board in this space can be bent after the tank is attached, the surface of the board is After adjusting the height of the decorative board and the height of the decorative board on the surface of the flange part 4' of the tank, this void is filled with adhesive synthetic resin 3 and solidified, so that the height of the decorative board can be adjusted during the processing process. can be adjusted. Therefore, the height of the decorative board on the surface of the tank flange portion can be made slightly lower, making it easier to drain water from the surface of the decorative board. Furthermore, since there is no exposed resin on the surface of the decorative top plate or in the vicinity of the tank, it is excellent in both function and design.

As shown in FIG. 2, the steps of this method are as follows: First, an opening A is provided in a decorative board 1 and a substrate 2 such as plywood, and the decorative board 1 is made to protrude toward the opening side of the substrate 2. At the upper end, a space 10 is provided between the lower surface of the decorative board and the lower surface of the decorative board by cutting along the periphery of the opening so that the space becomes narrower toward the side opposite to the opening.

Next, as shown in FIG.
is placed in between, and the flange portion 4' of the tank is made to correspond. In this case, it is preferable that the adhesive has water resistance, heat resistance, and no creep property, such as an epoxy resin-based adhesive.

Adhesive can be applied directly to the adhesive surface, or applied to paper with good impregnation properties, dried properly,
By making it into a so-called Dego film shape, cutting it into the required shape and inserting it into the adhesive part, it is possible to prevent uneven coating of the adhesive from flowing out, and it is possible to greatly improve workability.

It goes without saying that it is preferable to perform a pretreatment to improve adhesion, such as scratching the flange portion of the tank with a sandpaper.

Next, the decorative board and the tank are temporarily joined directly with an adhesive, and the adhesive 5 is cured by applying heat and pressure to the adhesive part from the outside of the flange. After the adhesive has hardened, attach each tank attachment device 6, 6a, 6b to the decorative top plate with a tank as shown in Fig. 1, and open the space 1 including the empty space 10.
1 is entirely filled with synthetic resin 3 to reinforce mechanical strength and obtain a finished product.

According to the present invention, in the undersing type tank installation method, a triangular cavity is provided at the upper end of the side surface of the substrate opening as described above, so a particularly thin decorative board or a flexible decorative board is used. When doing so, the difference in height between the base material and the flange of the tank can be easily adjusted, resulting in an excellent appearance.In addition, the flange of the tank can be made slightly lower, especially to drain water from the surface of the decorative board. It is extremely easy to do. By increasing the length of the adhesive layer on the back of the decorative board, even if a leak occurs at the adhesive part of the tank, water ingress can be prevented. Furthermore, since there is no exposed resin on the surface of the decorative board or near the tank, it has excellent functions such as water resistance (waterproofness) and design.

〔Example〕

The flat substrate 2 of the sink having the cross-sectional shape shown in FIG. 2 is made of 15 m/m plywood, and an opening A for attaching the tank is made in the center. At the same time, cut the upper end of the peripheral board around the opening (2' is the cutting part), and the opening side is 5m/m, the plane direction is 20m/m, and the depth is 0m/m.
A triangular sky 10 is provided. The following steps will be explained with reference to FIG. Paste the post-form type melamine resin decorative board 1 with a thickness of 0.8 m/m on the surface of the board 2 so that it protrudes from the board toward the opening side, and after setting the tank 4 and each tank mounting tool 6, 6a, 6b, tighten the mounting bolts. 6b, and when the decorative board surface of the tank flange part and the decorative board surface of the board part are level, a room temperature curing epoxy resin is applied to the space 11 formed by the board 2, the decorative board 1, and the tank 4. Pour in. At this time, the cavity 10 is also filled with epoxy resin. After this, the resin is solidified and the movement of the decorative board is stopped. After curing and reinforcing the resin, the side surfaces of the decorative board were finished to obtain a decorative top board with a tank having good performance such as water resistance and a good appearance.

Claims (1)

[Claims] 1. When attaching a tank-like object to a decorative top plate that consists of a board and a decorative board that covers the top surface and has an opening, the decorative board should protrude from the board toward the opening, and be placed at the upper end of the side of the opening of the board. A triangular cavity that gradually narrows from the opening to the opposite side is provided by cutting along the periphery of the opening between the bottom surface of the decorative board and the tank-shaped object on the bottom surface of the decorative board. A decorative top plate and a tank-like object, characterized in that after the space surrounded by the substrate, the decorative board, and the tank-like object including the above-mentioned sky is filled and solidified with a water-resistant synthetic resin having adhesive properties.
