Description

[Detailed Description of the Invention] The present invention relates to a structure for connecting bottom wall panels to each other in an assembled swimming pool.

Conventionally, when connecting bottom wall panels to each other, a urethane slab 101 previously formed in a shape matching the recess 3 is fitted into the recess 3 at the boundary between adjacent bottom wall panels via a lining layer 100. The former, in which the bottom wall panels 1 and 1 are connected to each other by applying a lining layer 102 and a gel coat layer 103 for surface finishing on the upper surface thereof, and the bottom wall panel 1 as shown in FIG. The flanges 2 protruding from the middle part of the wall are placed in the recess 3 on the flange 2 formed by fixing the rivet 104.
In the latter case, after filling the FRP lining layer 105, a gel coat layer 106 for surface finishing is applied on the lining layer 105.

However, in the former case, when a difference in level occurs between the bottom wall panels 1 and 1 as shown in FIG. 4 due to the relationship with the ground on which it is installed, the urethane slab 101 protrudes from the top surface of the panel 1 and rises. In this state, a connection part is formed between the bottom wall panels 1 and 1, resulting in a very poor appearance.Moreover, the gel coat layer 103 applied for surface finishing is applied with a brush or roller, so the thickness of the coating is very poor. It goes without saying that unevenness occurs, and sanding is required to even it out, which is time-consuming.In addition, sanding causes variations in the strength of the joints, and the surface cannot be finished smoothly. However, even in the latter case, there are problems such as complication of workability due to sanding, deterioration of the aesthetic appearance of the surface, and deterioration of bending strength due to the hollow portion 107 generated under the flanges 2, 2.

SUMMARY OF THE INVENTION The present invention aims to provide a structure for connecting bottom wall panels to each other in an assembled swimming pool, which can overcome the drawbacks of the prior art.

The basic structure for achieving this purpose is to make thin flanges protrude from the entire length of the lower end areas of the opposing end surfaces of adjacent bottom wall panels in opposing directions so that their tips abut against each other. A first FRP lining layer and a resin concrete layer are laminated from below in the recess formed on the flange of the resin concrete layer to form a mounting reference surface for the surface plate covering the upper surface of the resin concrete layer, and a second FRP is placed on that reference surface. The surface plate is fixed via a lining layer.

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

In the figure, 1 is a bottom wall panel, which is connected in large numbers to form the bottom wall A' of the assembled pool A. The side wall panel is erected on one edge of the short side of the rectangular pressure receiving surface a. Using a desired method such as the hand lay-up method, a sandwich structure of a desired thickness with a reinforcing member c such as a urethane slab built in is formed, and the upright surface b A thin plate-like flange 2 is provided on the entire length of the lower end area of the end face of the other side edge of the short side excluding the upright end face and both edges of the long side, respectively, protruding parallel to the top surface of the panel in the direction of the opposing end face of the adjacent bottom wall panel. Flanges 2, 2 at the boundaries of adjacent panels 1, 1 by forming
A recess 3 is formed on the top.

The recess 3 is formed by butting the end surfaces of the flanges 2 against each other in relation to the adjacent bottom wall panels 1, 1, and the first FRP lining layer 4 and resin concrete are laminated in order from the bottom to the recess 3. A surface plate 7 is fitted through the layer 5 and the second FRP lining layer 6.

The first FRP lining layer 4 has the function of integrating the flanges 2, 2 of the adjacent bottom wall panels 1, 1, and the function of reinforcing the bottom surface of the recess 3.

The resin concrete layer 5 is a material that is extremely strong in terms of strength, has excellent watertightness, and has some fluidity at first, but solidifies over time.
This material is filled in the recess 3, and a mounting reference surface 5a for the surface plate 7, which is covered with the second FRP lining layer 6 laminated as an upper layer, is formed on the upper surface.

Even if there is a level difference between the bottom wall panels 1 and 1 due to the relationship with the ground or floor slab on which it is installed, the mounting reference surface 5a allows the surface plate 7 to fit into the upper area of the recess 3 regardless of the level difference. It is a reference surface for making the surface smooth, and is formed by leveling it with a fluid when it is in a viscous state.

The second FRP lining layer 6 has both the function of fixing the top plate 7 and the function of reinforcing the top plate 7.

The surface plate 7 is formed of FRP or other necessary materials into a plate shape having a width almost equal to the opening of the recess 3, and is fixed to the second FRP lining layer 6 before solidification, that is, in a viscous state, so that it can be used for the bottom wall. A recess 3 is continuously covered between the upper surfaces of the panels 1 and 1.

Reference numeral 8 denotes a joint material filled between the surface plate 7 and the bottom wall panel 1, and is formed by filling a necessary material such as polyester through a glass roving 8'.

Since the present invention is constructed as described above, it has the following advantages.

Since it has a four-layer structure of the first FRP lining layer, resin concrete layer, second FRP lining layer, and surface plate, it has strong tensile and bending strength and can improve connection strength.

Even if there is a level difference between adjacent bottom wall panels due to the relationship with the ground where they are installed, the mounting reference surface on the resin concrete top surface can be formed regardless of the level difference, so the bottom wall panels can be placed continuously on the top surface of each other. The surface plate can be placed and fixed, and there is no need for sanding, so the surface can be formed beautifully.

Since no cavity is formed on the lower side as in the conventional case, an even stronger connection structure can be achieved, and improved durability can be expected.

Thus, the intended purpose can be achieved.
