Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a structure for repairing an aging swimming pool.

[Conventional technology and its problems]

Traditionally used pools are made of concrete.
They can be roughly divided into metal and FRP products, but after long-term use, concrete products may crack and become unusable due to weathering and erosion, and metal products may become unusable due to chlorine used in swimming pools. Affected by sterilizing agents, local corrosion occurs particularly at welded parts, causing water leakage.Furthermore, in the case of FRP, the surface color fades due to ultraviolet rays, and scratches and minute cracks occur, making it unsightly in appearance even though there is no water leakage. In either case, repairs are required.

Traditionally, renovations for this purpose involve applying unsaturated polyester or epoxy resin to the entire wall of the pool to be renovated, laying glass fiber on top to defoam, and then applying the above resin again. It mainly uses a structure that repeats many times (the product formed by this is called FRP).

However, when such a structure is used, there is a problem that the work is complicated and time-consuming, and therefore, the construction time is required, which increases the cost.

[Technical issues]

The technical problem of this invention is to minimize the application area of synthetic resin lining material such as FRP in order to provide an economical pool repair structure that requires less time and effort when renovating an aging pool. There is a particular thing.

[Technical means]

The technical means of this invention is a side wall panel made of synthetic resin such as FRP which has a square planar shape and has a filler applied to the back side, and a deck border finish made of synthetic resin such as FRP which has a cross-sectional shape and has a filler applied to the back side. Prepare a panel and a bottom wall finishing panel made of synthetic resin such as FRP that has a square planar shape, and press the side wall finishing panels parallel to each other across the entire length of the existing pool side wall, and also connect the top end of the side wall finishing panel with the top edge of the side wall finishing panel. A deck border finish panel is crimped across the entire length of the side wall of the existing pool with intervals to check for leakage of filler material, and the bottom wall finish panel is laid parallel to the bottom of the existing pool with cushion material interposed on the back side. At the same time, a synthetic resin lining material such as FRP is embedded and fixed between the side wall finishing panels, between the bottom wall finishing panels, and between the side wall finishing panels and the bottom wall finishing panels.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

The drawings show an aluminum pool as the existing pool. This pool consists of an aluminum side wall panel A ₁ - 1 that extends horizontally from the upper end of the pool side wall A ₁ - 2, which is formed by joining a number of panels A 1 - 2 by welding, etc., and an aluminum bottom at the lower end of the pool side wall A ₁ . The pool bottom A2 is formed by laying a large number _of panels _A2-1 .

This existing pool consists of deck border finishing panel 1 for repairing deck _a1-1 , side wall finishing panel 2 for repairing pool side _a1-3 , bottom wall finishing panel 3 for repairing pool bottom _a2 , and FRP etc. It is repaired using a synthetic resin lining material 5.

The bottom wall finishing panel 3 leaves the mounting flange 3-1 on the periphery and provides a recess 3-2 of a predetermined height on the back surface, thereby indirectly forming a step 3-3 (gap) on the periphery. , is a planar rectangular sheet-like material molded from synthetic resin such as FRP with a desired length and desired width relative to the short width of the pool bottom _A2 , and the cushion material 7 is accommodated in the recessed portion 3-2. Mounting flange 3-1 in the state
They are laid and fixed in parallel to each other on the entire surface of the pool bottom _A2 by fixing them with 8 rivets.

The cushion material 7 is made of a foamed material such as a synthetic resin with some elasticity and is formed into a sheet shape having a height slightly higher than the height of the recess 3-2, and is adhesively accommodated in the recess 3-2. Alternatively, as shown in the figure, it may be placed in advance at a location where the bottom wall finishing panel 3 will be laid, so that when the panel 3 is laid, it can be automatically accommodated in the recess 3-2.

As is conventionally known, the lining material 5 includes a curing agent,
It is made of unsaturated polyester or epoxy thermosetting resin containing additives such as accelerators and glass fiber, and is installed between the mounting flanges 3-1 and 3-1 of the adjacent bottom wall finishing panels 3 and 3. A tape 9 made of foamed polyethylene, urethane, etc. is pasted over the entire length to prevent the glass fibers from falling.
By repeating the operation of placing the resin agent and glass fiber in the upper step part 3-3, degassing them while impregnating them, and embedding the resin agent again, it is embedded in the step part 3-3. Fix it.

The deck border finishing panel 1 includes a deck surface portion 1-1 that finishes the deck a ₁ -1 of an existing pool, and a deck surface portion 1-1 that is hung vertically from the tip of the deck surface portion 1-1 to finish the deck surface a _{1 -1} of the existing pool.
3.It is made of synthetic resin such as FRP and is several tens of centimeters long, formed by the upper corner surface 1-2 that finishes the upper end part.
~ several meters, the width of the deck surface part 1-1 is about 50 to 100 mm, and the height of the upper corner part 1-2 is about 20 to 50 mm,
A large number of inverted truncated cone-shaped recesses 1-3 are provided in the length direction of the deck surface 1-1 at appropriate pitch intervals such as 125 mm, and the deck surface 1-1 and the upper corner surface 1-2 are The back of the corner with the deck of the existing pool
The curvature is made smaller than the curvature of the boundary between _a1-1 and the pool side surface _a1-3 so that a gap 10 is formed over the entire length as shown in the figure, and the back surface of the upper corner surface 1-2 is An inclined surface 11 which is inclined toward the inside of the pool is formed at the lower edge portion.

The side wall finishing panel 2 has lower mounting flanges 2-1 stepped on three edges other than the upper edge opposite to the lower edge of the upper corner 1-2 of the deck border finishing panel 1, and a cushion material 7 on the back side. It is a sheet-like object molded from synthetic resin such as FRP with a desired length and a desired width corresponding to the depth of the pool, with a recessed portion 2-2 of a predetermined height for accommodating the pool. An inclined surface 2-3 forming a V-shape with the inclined surface 11 of the upper corner surface 1-2 is formed on the upper edge, and a suitable pitch such as 125 mm is formed in the vicinity of the upper edge along the entire length. A large number of inverted truncated cone-shaped recesses 2-4 are provided at intervals.

Such a deck border finished panel 1 is provided with a filler 6 such as silicone filled on the back side and in the gap 10, and before the filler ₆ hardens.
Crimp the necessary sheets in the length direction along 1, and then press the recess 1-
It is fixed by sewing it to the deck a ₁ -1 in 3 with rivets 8.

At this time, the filler material 6 leaks from all sides of the deck border finished panel 1 due to the crimping operation, but the leakage material is wiped off except for the lower edge of the upper corner portion 1-2.

The side wall finish panel 2 is the entire back surface except for the cushion material 7, or the deck border finish panel 1
The filler 6 is applied only to the back surface of the upper area near the upper corner 1-2, and before the filler 6 hardens, it is applied between the lower edge of the upper corner 1-2 of the deck border finished panel 1. Position the upper edge at a position that ensures a leakage confirmation interval 4 of about 2 to 3 mm, and crimp the necessary pieces in the length direction of the pool side surface a ₁ - 3, and then press the inside of the recess 2-4 and the mounting collar 2-1. are fixed by sewing them to the pool side surfaces _a1-3 with rivets 8.

At this time, the filling material 6 leaks from all sides of the side wall finishing panel 2 due to the crimping action, or leaks only from the upper edge surface.
Then, it is confirmed that the connection part with the side wall finishing panel 2 is completely sealed, and any overflowing material is wiped off on the spot.

In addition, between the side wall finishing panels 2 and 2, and between the side wall finishing panels 2 and the bottom wall finishing panels 3, there is a mounting flange 2.
A tape 9 made of foamed polyethylene, urethane, etc. is pasted along the entire length between -1 and 2-1 and between the mounting flanges 2-1 and 3-1 to prevent the glass fibers from falling to the bottom of the pool. Lining material 5 similar to the repair of a ₂
perform the embedding work.

In addition, 12 is a filler to be filled into the recesses 1-3 and 2-4, 13 is a gel coat layer applied on the lining material 5, and 14 is a resin putty for filling the steps. Putty 14 may be filled instead of the tape 9, and the FRP lining material 5 may be embedded thereon.

By the way, in this example, 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 is flush with the wall. Ori,
When the side wall finishing panel 2 and the deck border finishing panel 1 are crimped, care is taken to prevent the side wall finishing panel 2 itself from being deformed in a wave-like manner due to the repulsive pressure of the filler 6 on the back side. Also,
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 6 in the gap 10 will still function as a weir. This will prevent pool water from flowing out,
This has the advantage of preventing overflowing water from flowing into the deck a ₁ -1.

Regarding the renovation of the pool side wall corners, it goes without saying that deck border finishing panels 1 and side wall finishing panels 2, which have an L-shaped planar shape as shown in the drawings, are used, and in the examples, explanations are given for aluminum pools. However, it goes without saying that it also covers concrete, other metal pools, and FRP pools.

[Function and effect of the idea]

As described above, the present invention consists of a side wall panel made of synthetic resin such as FRP that has a square planar shape and has a filler applied to the back side, and a deck border finish made of synthetic resin such as FRP that has a cross-sectional shape and has a filler applied to the back side. Prepare a panel and a bottom wall finishing panel made of synthetic resin such as FRP that has a square planar shape, and press the side wall finishing panels parallel to each other across the entire length of the existing pool side wall, and also connect the top end of the side wall finishing panel with the top edge of the side wall finishing panel. A deck border finish panel is crimped across the entire length of the side wall of the existing pool with intervals to check for leakage of filler material, and the bottom wall finish panel is laid parallel to the bottom of the existing pool with cushion material interposed on the back side. At the same time, a synthetic resin lining material such as FRP was embedded and fixed between the side wall finishing panels, between the bottom wall finishing panels, and between the side wall finishing panels and the bottom wall finishing panels, so the following effects were achieved. be.

A repaired wall can be formed by embedding and fixing the lining material between the side wall finishing panels, between the bottom wall finishing panels, and between the side wall finishing panels and the bottom wall finishing panels, so that the area to which the lining material is applied can be minimized.

Therefore, repair work is easy, and compared to the conventional work of repeatedly applying the FRP lining material, which involves impregnating and defoaming, over the entire surface, it is less labor-intensive and the construction period is shorter. , economical.

Because it is divided into side wall finishing panels, deck border finishing panels, and bottom wall finishing panels,
It is not bulky, and even if the target pool for renovation is installed indoors, it can be easily carried in through the entrance, making it extremely easy to carry.

Furthermore, the deck border finishing panels and side wall finishing panels are crimped to the deck border and pool side parts, respectively, at intervals to check for leakage material, but at that time, it was confirmed that there was no leakage material leaking from the gaps to check for leakage material. This allows you to check the degree of sealing at the connection between the upper edge of the side wall finishing panel, which is most effective in preventing the outflow of pool water and the inflow of water that overflows to the deck surface, and the lower edge of the deck border finishing panel. It reliably prevents water leakage and does not cause deterioration of durability.

Thus, the intended purpose can be achieved.
