Description

[Detailed description of the invention] This invention relates to counters.

BACKGROUND ART Conventionally, in kitchen counters for sinks and washroom counters, top plates have been used in which the surface of a wooden substrate such as plywood or particle board is treated with a decorative board or resin to make it waterproof. However, in such a top plate, when a hole is drilled and a water supply pipe for installing a water counter is passed through, the wooden substrate is exposed on the inner surface of the hole, so water transmitted from the water supply counter to the outside surface of the water supply pipe and the ceiling are exposed. There is a problem in that water spilled onto the board seeps into the top board from the inner surface of the hole, causing corrosion. Therefore, in the past, it was not possible to pass the water supply pipe through the top plate, and the water supply pipe was taken out from the wall or behind the counter. It is hoped that this will be possible.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a counter that can prevent water from penetrating into the top plate and prevent corrosion of the top plate while allowing a water supply pipe for attaching a water supply pipe to pass through the top plate. be.

An embodiment of the invention is shown in FIGS. 1 to 4. In the figure, 1 is a kitchen counter,
It consists of a top plate 2 and a box-shaped main body 3. The box-like main body 3 has a door 4 on the front side, and is installed on the floor via an underframe 5. 6 is a trailing edge material provided along the trailing edge of the top plate 2. Two sinks 7 and 8 are installed side by side on the top plate 2, and a drain pipe 9 is connected to the drain port of the sink 8.
is connected. The top plate 2 includes a wooden substrate 2a made of plywood, particle board, or laminated wood, with a water-resistant decorative material 2b on the front surface and a water-resistant back material 2c on the back surface. Note that instead of the decorative material 2b, a water-resistant surface decoration may be applied with resin such as polyester or acrylic, or a stainless steel plate or the like may be applied. The top plate 2 is provided with a vertical hole 10 at a position behind the sink 8, and the vertical hole 10 is filled with a waterproof material 11 as shown in FIG. This vertical hole 10 has a hole diameter that is
The outer diameter of the water supply pipe 12 is set to be larger than the outer diameter of the water supply pipe 12 that penetrates the water supply pipe 12. Further, the waterproof material 11 is made of, for example, urethane resin, polyester resin, epoxy resin, silicone resin, or the like.

This counter is made by cutting the waterproof material 11 from the upper surface to the lower surface so that the hole diameter is the same as the diameter of the water supply pipe 12 at the site.
A water supply pipe 12 raised from the floor is passed through this through hole 13, and a water supply pipe 1 is inserted into the upper end of the water supply pipe 12.
Install 4.

In this way, since the hole diameter of the vertical hole 10 is set larger than the outer diameter of the water supply pipe 12, the waterproof material 11 can cover the inner peripheral surface of the vertical hole 10 even after the water supply pipe through hole 13 is bored in the waterproof material 11. Therefore, even if the water supply pipe 12 is inserted into the water supply pipe penetration hole 13, water that flows down from the water supply pipe 14 to the outer surface of the water supply pipe 12, water that spills onto the top plate 2, etc. It does not seep into the wooden substrate 2a from the inner surface of the vertical hole 10, and corrosion of the substrate 2a is prevented. In addition, since the water supply pipe through hole 13 can be drilled on site according to the outer diameter of the water supply pipe 12, even if the water supply pipe 12 has various outer diameters, it will fit snugly into the waterproofing material 11 and penetrate easily. Can be equipped.

Although the above embodiment is applied to a kitchen counter, the present invention can also be applied to a wash counter to which a wash bowl is attached.

As described above, the counter of the present invention includes a top plate having a vertical hole with a diameter larger than the diameter of the water supply pipe and whose upper surface is waterproofed, and a top plate with a waterproofed upper surface and a vertical hole with a diameter smaller than the diameter of the vertical hole filled with the vertical hole. Equipped with a waterproof material that allows water supply pipe insertion holes to be freely cut and drilled from the top to the bottom, allowing the water supply pipe for installing the water supply pipe to penetrate through the top plate while preventing water from seeping into the top plate. This has the effect of preventing corrosion of water and allowing various water supply pipes with different outside diameters to be inserted into the waterproof material in a well-fitted manner.
