Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel for repairing parts of aging swimming pools, including water inlets, drains, circulation inlets, and other water inlets.

[Prior art and its problems]

Conventionally, swimming pools can be broadly classified into materials made of concrete, metal, and FRP, but after long-term use, concrete can become unusable due to cracks and unevenness of the surface due to weathering and erosion. If the pool is made of metal, it will be affected by the chlorine sterilizer used in swimming pools, resulting in severe local corrosion, especially in the welded parts, and the potential difference between the pool and the ground will accelerate corrosion and cause water leakage.Furthermore, if the pool is made of FRP, The surface color may fade due to the chlorine sterilizer or ultraviolet rays,
Scratches and minute cracks occur, and although there is no water leakage, the appearance is unsightly, and in either case, repairs are required.

When renovating this pool, we had to apply unsaturated polyester or epoxy resin over the entire pool, lay glass fiber on top to defoam, and then reapply the above resin several times. A repeating method is mainly used (the product formed by this method is the so-called FRP).

However, in the case of such prior art, there is a problem that the work is complicated and time-consuming, and therefore the cost is high because it requires a long construction period.

In order to solve this problem, the applicant of the present application has already filed Japanese Patent Application No. 1983-57976.

In this prior art, a surface finishing panel in which an adhesive is fixed to the back side of a synthetic resin sheet such as FRP having a square planar shape is adhesively laid in parallel to the side wall and bottom wall of the pool body, respectively, and the panels are mutually connected. By embedding and fixing the FRP lining material in the gap between the two, the area to which the lining material is applied, which is a wet process, is minimized, simplifying the repair work and reducing the number of days required to complete the repair. be.

However, in the case of this prior art, the repair panels used for repairing the parts of the wall facing the water inlet, such as the water supply inlet, drain outlet, circulation inlet, etc. in the existing pool, are This is handled by simply opening a guide port that communicates with the water port in the opposing part and attaching metal fittings such as a perforated plate to the guide port. It is riveted or bolted or nutted to the existing pool wall through the
This adhesive body is made of a material with cushioning properties to absorb the pressure of swimmers, the fluid pressure during swimming, and the pressure of falling when installing a depth adjustment platform inside the pool, and it expands and contracts when the various pressures listed above are applied. As a result of repeating this process, there have been cases where the rivets, bolts, and nuts mentioned above have loosened and metal fittings such as perforations have come apart.

[Technical issues]

The technical problem of this invention is to prevent metal fittings such as perforated plates from disassembling even if they are fixed with rivets, bolts, or nuts, in the part facing the water opening of the existing pool, that is, opening in communication with the water opening. The purpose of this invention is to form a non-deformable part in a metal fitting mounting part such as a perforated plate around the guide opening.

A resin putty 14 may be filled instead of the tape-like material 9, and the FRP lining material 5 may be embedded thereon.

By the way, in this embodiment, the special panel 10
0. The total height X of the bottom wall finishing panel 3, side wall finishing panel 2, and deck border finishing panel 1 is all 6 mm, so that when the repaired wall is formed, the repaired wall will be flush with the special panel. When the 100 side wall finishing panel 2 and the deck border finishing panel 1 are crimped, each panel 100, 2, 1 is prevented from being deformed in a wave-like manner due to the repulsive pressure of the filler 6 on the back side. In addition, since the filler 6 is also filled in the gap 10 and solidified, even if the filler on the back side breaks due to long-term use, the thick filler in the gap 10 will not be damaged. The material 6 acts as a weir, and has the advantage of preventing the outflow of pool water and the inflow of overflowing water into deck _a1-1 .

Regarding the renovation of the pool side wall corner, as shown in the drawing, deck border finish panel 1, side wall finish panel 2, and special panel 1, which have an L-shape in plan, will be used.
It goes without saying that 00 is used, and target pools include aluminum, concrete, other metal pools, and FRP pools.

[Function and effect of the idea]

The present invention has a rectangular shape as described above.
A recess is provided on the back side of the panel main body made of synthetic resin such as FRP, excluding the peripheral edge and the part facing the water entrance of the existing pool, and the recess has a thickness that slightly protrudes from the level of the back surface of the panel main body. The panel body is lined with cushion material, and the part of the panel body facing the existing swimming pool's water opening is thickened to form a mounting seat whose back surface is flush with the back surface of the peripheral edge of the panel body, and the mounting seat is attached to the water opening. Since the guide port that communicates with is opened, the following effects are obtained.

The mounting part of the perforated plate and other metal fittings around the guide port, which opens in communication with the water supply port, is thickened to form a mounting seat that does not deform, so the perforated plate and other metal fittings can be secured with rivets, bolts, or nuts. As a result, even if it is fixed to the existing pool wall, the mounting seat, which is the part where the rivets, bolts, and nuts are fixed, will deform even if it is subjected to tightening pressure, flowing water pressure during swimming, or falling pressure from the water depth adjustment platform. Never.

Therefore, it was possible to provide a new repair panel in which rivets, bolts, and nuts do not loosen, do not disassemble, and can constitute a strong water opening repair structure over a long period of time.

As a result, we were able to achieve our intended purpose.
