Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure for treating the edges of a renovated wall of an aluminum swimming pool.

[Prior art and its problems]

Traditionally, aluminum pools have the property that the bottom of the pool, which is in contact with the ground, corrodes in a verminous manner due to the influence of the potential difference with the ground, and eventually pitting corrosion occurs where holes open up everywhere. The side walls of the pool that are not in contact with each other may also fade due to the influence of the chlorine sterilizer, and both require renovation, so the applicant has filed U.S. Pat. There is.

This prior art has a square planar shape and is made of synthetic resin with a filling material on the back side. It is laid parallel to the existing pool wall and riveted, and the ends of each panel are made of synthetic resin such as FRP. By connecting them with lining material to form a renovated wall, and by focusing on the work of laying surface finishing panels, the area to which lining material is applied can be reduced, resulting in a short construction period and hassle-free installation of existing swimming pools. This is to repair the wall.

However, problems also occurred with this prior art. During the experiment, water leaked from the bottom of the repaired wall.

When investigating the cause of this problem, defects were discovered from the side to the bottom of the repaired wall.

This phenomenon occurs when a surface layer is left behind in the existing pool wall facing the peripheral edge of the renovated wall, and a cavity is formed behind it, and this cavity forms a hole in the bottom of the existing pool wall due to pitting corrosion. They were in communication.

After elucidating this phenomenon, we found that among the joints between aluminum and the surface finishing panel that are joined underwater, there are certain areas where aluminum is joined to the surface finishing panel from the end part that is in constant contact with water or intermittently in contact with water. The inside of the aluminum is first corroded by water to form a cavity, leaving a thick surface layer, and then the water corrodes by penetrating not in the thickness direction of the aluminum but over the entire joint with the surface finish panel. A follow-up study over time revealed that the area of the cavity gradually expands due to the corrosion, and corrosion progresses inside the aluminum until the cavity finally communicates with the hole created by pitting corrosion. Ta.

This phenomenon is unique to aluminum, and when we experimented with other materials (components) joined instead of FPR material, a similar water leakage phenomenon occurred.

[Technical issues]

The technical problem of the present invention is to prevent the infiltration of water, which is a factor in the formation of cavities formed in the aluminum, using the riveted portion at the peripheral edge of the repaired wall, thereby preventing further intrusion of water.

[Technical means]

The technical means taken to achieve the above technical problem was to interpose a foaming packing with a low foaming rate between the back surface of the peripheral edge of the repaired wall and the existing pool wall, and press the foaming packing. Renovate the peripheral edge of the wall so that
It was fixed to the existing pool wall using aluminum rivets placed at appropriate intervals.

[Effect]

The effects of the technical means of the present invention are as follows.

Γ A foaming packing with a high foaming rate, which is interposed between the peripheral edge of the repaired wall and the aluminum pool wall and is compressed by rivets, follows the formed cavity and elastically restores its shape. It closes the cavity to stop water from entering and prevent further cavities from forming.

〔Example〕

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

The drawing shows a swimming pool made of aluminum.

This existing pool has an aluminum bottom panel attached to the lower end of the pool side peripheral wall b, which is formed by butt-splicing a number of aluminum side wall panels b'.
A pool bottom wall a is formed by laying a large number of sheets a'.

This pool bottom wall a is a step-like bottom panel that gradually increases the water depth toward the center in the short direction of the pool.
This is a well-known structure formed by overlapping and splicing a large number of panels a' and butt-splicing the bottom panels a' in the longitudinal direction.

This pool is provided with a renovated wall B formed on its inner surface using a surface finishing panel 1 made of synthetic resin, a filler 2, a lining material 3 made of synthetic resin, and putty 4 for bonding metal.

The surface finishing panel 1 leaves the mounting flange 11 on the periphery and provides a recess 21 of a predetermined height on the back surface, thereby indirectly forming a step 31 (gap) on the periphery, and forming a step 31 (gap) on the bottom wall a of the pool. It is a rectangular sheet-like material having a length of 1/2 of the short width and a width of a desired width such as 2 m, and is filled into the recess 21 as shown in FIGS. 3 and 4. By fixing the mounting flange 11 with aluminum rivets 100 in a state in which the material 2 is accommodated, the pool bottom wall a and the pool side peripheral wall b are fixed.
They are laid parallel to each other and fixed.

Among these surface finishing panels 1, the top surface finishing panel 1 laid and fixed to the pool side peripheral wall b has a thick wall part 41 with a thickness of about 10 mm and a length of about 100 mm in the upper end area.
The upper end of the thick portion 41 is fixed to the upper limit of the pool side peripheral wall b using aluminum rivets 100 inserted through recesses 51 formed at appropriate intervals.

The metal adhesive putty 4 is urethane-based and is used to attach the lower end of the pool side peripheral wall b and the bottom panel connected thereto.
After sanding the step 5 between the pool a' and the bottom panels a' and a' adjacent in the lateral direction of the pool, the step 55 is absorbed by painting.

Also, among this adhesive putty 4, the pool side peripheral wall b
The corner adhesive putty 4-1 to be applied within the step 5 between the lower end and the bottom panel a' connected thereto is applied to the step 5.
The step filling part 4-1' and the filling part 4-
1', and an extension part 4-1'' that protrudes higher than the lower end of the pool-side peripheral wall b and extends halfway up the vertical surface b''. As for the intermediate bonding putty 4-2, apply it to the pool bottom wall a in advance so that there are no gaps when the surface finishing panel 1 is laid and fixed with the filler 2 interposed as described above. do.

The filler 2 is made of a foamed material such as a synthetic resin with some elasticity, and is formed into a sheet shape having a thickness that is the same as or slightly higher than the height of the recess 21, and is either adhesively accommodated in the recess 21, or As shown in the figure, when the surface finishing panel 1 is laid on the temporary bottom surface X, the surface finishing panel 1 is automatically accommodated in the recess 21 thereof.

As is conventionally known, the lining material 3 is made of a thermosetting resin such as unsaturated polyester or epoxy containing additives such as a curing agent and an accelerator, and glass fiber. By repeating the steps of embedding it on the mounting flange 11 at the lower part, placing glass fiber thereon, degassing it, and embedding the resin agent again, the stepped part 31
The panels 1 and 1 are connected to each other by embedding and fixing in the upper part and all between the edges of the panels 1.

After this lining material 3 is solidified, it is sanded and further coated with a colored resin 3' to form a surface color, thereby forming a repaired wall B.

In detail, the surface finishing panel 1 to be laid on the temporary bottom surface
As shown in FIG.
In the case of the surface finishing panel 1, which is placed so that its end surface is in flush contact with the rising surface of 1' and fixed by fixing with aluminum rivets 100, and laid on the pool side peripheral wall b, Mounting collar 11
The mounting flange 11 is fixed by riveting 100 with the end surface brought into flush contact with the upper end surface of the extension section 4-1''.

The function of the renovated aluminum pool wall will now be explained.

The level difference 5 between the pool side peripheral wall b and the bottom panel a' continuous to the lower end of the side peripheral wall b, and the level difference 5 between the bottom panels a' and a' are covered with adhesive putty 4 to be applied. ,
A temporary bottom surface X that is flush with the pool bottom wall a is formed. When the surface finishing panel 1 is fixed on the adhesive putty 4 with rivets 100 in this state, the function of the packing 6 also works to form a watertight connection part (screwed part). Then, the gaps created on the adhesive putty 4, the mounting collar 11, and the step 31 exposed on the periphery of the surface finishing panel 1 are sealed flush with the lining material 3, forming a flat repaired wall B, and at the same time forming a connection area. (screw fixing part)
further protects it from pool water.

In the repaired wall B, the back surface of the peripheral end portion and the pool-side peripheral wall a are sealed with a foaming packing 200 with a low foaming rate interposed therebetween.

The foamable packing 200 is made of vinyl chloride with a foaming rate of about 2 to 10 times, and is used to cover the thick wall portion 4 of the surface finishing panel 1 composing the peripheral edge of the repaired wall B.
1, the entire circumference of the pool-side peripheral wall b on the back surface is pasted using an adhesive or the like, and the peripheral end of the repaired wall B is sealed with rivets 100.

61 is a gel coat paste that closes the recessed part 51 after the rivet 100 is fixed, and 71 is a gel coat paste that fills the thick part 41.
This is a urethane sealing material that hides the small gap between the upper end and the pool side peripheral wall b.

While the above embodiment is an example in which the deck portion was not modified, FIG. 7 is an example in which the deck portion was also modified.

Surface finishing panel 1 for deck border with thick walled parts 41, 41 formed on both ends in the width direction (made of synthetic resin, etc.)
FRP (made of FRP) is inserted through the concave portions 51 which are provided at appropriate intervals in the length direction as in the previous embodiment, and fixed with rivets 100, and the surface finishing panel 1 for this deck boater and the pool Putty 4 for metal adhesion between side peripheral wall b and surface finishing panel 1 for repair
Using an adhesive or the like, the entire circumference of the pool deck wall C on the back side of the thick wall portion 41 of the surface finishing panel 1 constituting the peripheral end of the repaired wall B formed by covering with Paste foam packing 200, which increases the foaming rate by 2 to 10 times, and rivet 100.
The peripheral end of the repaired wall B is sealed by a stopper.

In addition, at the longitudinal end of this surface finishing panel 1 for deck borders, a mounting flange 11 is stepped in the same way as other finishing panels 1, and after fixing with rivets 100, the lining material 3 is embedded and fixed. The panels 1 and 1 are connected to each other.

Incidentally, in this example, if an aluminum pool excluding the pool deck wall C has a renovated wall B, an aluminum pool that also includes the pool deck wall C has a renovated wall B.
We have explained the treatment of the end of the repaired wall B in the case of having The invention also targets the end treatment of the repaired wall B.

[Effects of the invention] Since the present invention is constructed as described above, it has the following advantages.

Γ Corrosion phenomenon specific to aluminum occurs at the peripheral edges of the repaired wall, including the pool side walls and pool deck walls. This prevents water from entering any further cavities formed by the process, and prevents water from penetrating into the bottom wall of the pool due to pitting corrosion from the peripheral edge of the repaired wall. Since no communication path is formed leading to the hole, water leakage can be prevented.

Thus, the intended purpose can be achieved.
