The prefabricated pool as described above is used as a children's pool.

However, in the conventional type, the work of connecting the segments is troublesome, the unit easily disassembles once assembled, and requires a large storage space even when not in use.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides a connecting device for a prefabricated pool, which allows segments to be easily connected and disassembled, and which does not cause any inconvenience when used as a pool at the connected portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the sectional pool connection device according to the present invention will be further described with reference to preferred embodiments shown in the accompanying drawings.

In FIG. 1, a pool or tank body assembled using the connecting device according to the present invention is shown as a whole with reference numeral 1.

The tank body 1 is constructed by connecting a plurality of segments 2, 3 and 4 made of fiber-reinforced plastic products.

As shown in FIG. 2, each of these segments 2, 3, and 4 has a portion corresponding to the bottom (hereinafter simply referred to as the bottom) when configured as a tank with a filler material 5 made of polyurethane foam or the like. The thickness is given by wrapping the fiber-reinforced plastic with the fiber-reinforced plastic.

However, when configured as a tank, the portion of each segment that corresponds to the peripheral wall is not provided with a filler such as the bottom, and the fiber-reinforced plastic material that partitions the end face at the bottom of the segment is The wall 6 extends to form the depth of the tank, and is bent outward from a predetermined height.

That is, the peripheral wall of the tank body 1 is composed of an inner and outer double wall 6°7, with a space interposed between the inner wall 6 and the outer wall 7.

Since the connecting edges provided on each segment to connect each segment have the same configuration, by explaining the case of connecting any two segments 2 and 3,
The configuration of the connecting edge will be made clear.

A groove 8 is formed along the connecting edge of each segment for connecting the segments.

This groove 8 includes an overhanging portion 9 formed integrally with the fiber-reinforced plastic part of the segment so as to form a depth approximately the same as the thickness at the bottom of the segment, and an upright portion rising from the overhanging portion. It is divided by a section 10.

When connecting two segments 2 and 3 having such a configuration, the rising portion 10 of each segment 2 and 3 is
are brought into contact with each other with a backing 11 made of foamed rubber interposed therebetween.

Next, a support piece 12 made of extruded aluminum is arranged on the inner surface of each rising portion 10, that is, on the inner surface of the groove 8, and these support pieces 12 are arranged from the groove 8 of the connecting edge of one segment 2 to the connecting edge of the other segment 3. A tightening member consisting of a bolt 13 inserted into the groove 8 and a nut 15 screwed together via a washer 14 is used to connect the two parts in a removable manner.

The support piece 12 has a small protrusion 16 formed at its upper end and a large protrusion 17 at its lower end.

A gap 18 is formed between the large projecting piece 17 and the bottom of the groove 8.

When the two segments 2, 3 are connected in this way, two adjacent grooves 8, 8 appear at the joint connection.

These two adjacent grooves are closed by one cover plate 19, the surface of the plate part 20 of the cover plate 19 providing a flat connecting surface to the surface of each segment, and at the same time its underside It abuts against the upper end of the jointly connected rising portion 10.10.

This cover plate 19 is made of a molded product of a material having some degree of elasticity, such as soft vinyl chloride or hard vinyl chloride, and is provided with support legs 21 and 22 at both ends of the plate portion 20.

These support legs 21, 22 are inclined such that their tips approach each other, and their tips 23, 24 are bent in opposite directions.

The tips 23 and 24 of the support legs 21 and 22 are respectively inserted into the gap 18 between the large protrusion 17 of the support piece 12 and the bottom of the groove 8 and held therebetween.

Furthermore, ribs 25 and 26 are formed on the inner surface of the plate portion 20 of the cover plate 19 so as to be located on both sides of the small projection piece 16 for reinforcement and to prevent slippage due to elastic deformation.

The shape of such ribs can be selected as appropriate, or the inner surface of the plate portion 20 can be made thicker from the vicinity of the small projection 16 to the side.

According to the structure of the connecting device according to the present invention shown in FIG. (It is installed using the elastic deformation of the grooves 8, 8, and the tips 23, 8 of the support legs 21, 22 of the cover plate are closed.
24 are in contact with the bottom of each groove 8 and support pieces 12
It is held by the large projecting pieces 17 of.

As a result, even if a person rides on the cover plate 19, the load applied to the plate part 20 is applied to the central part of the plate part by the upper surface of the rising part 10 and the small protrusion piece 16 of the support piece 12, and the load applied to the plate part 20 is Both sides of the section are supported by support legs 21 and 22.

That is, the plate portion 20 of the cover plate 19 has support legs 21 on both edges.
．． 22 and the upper surface of the rising part 10, there is an advantage that even if the cover plate 19 is made of an elastic material, it will not bend easily in response to a load applied from above to the plate part 20. .

Furthermore, when a load is applied to the plate portion 20, the support legs, which are generally vertically erected, tend to be restricted by the segment side walls of the groove 8 and bend into the groove, so as shown in FIG. Since the support legs 21 and 22 are arranged in advance so as to be inclined inward in the groove, and their tips 23 and 24 are fixed, the load on the cover plate can be sufficiently supported.

Further, as described above, since this cover plate is made of an elastic material, it can be easily attached to and detached from the load by utilizing its elastic deformation.

FIG. 3 shows another embodiment of the coupling device.

According to the connecting device according to this embodiment, the support legs 21 and 22 of the cover plate 19 are formed by grooves 8 extending vertically from the vicinity of each end of the plate portion 20.
The lower ends of the support legs extending toward the bottom and abutting the bottom are laterally jutted out to provide a sufficient support surface for the bottom.

The laterally projecting inner portions 27 and 28 are similar to the embodiment shown in FIG.
It is disposed and held in the gap 18 between the large projecting piece 17 and the bottom of the groove 8.

Ribs 29 and 30 are formed on the inner side of the support leg slightly above the large projecting piece 17.

Further, both ends of the cover plate 19 in the width direction are bent into the groove so as to contact the segment side walls of the groove 8 to form the ear portions 31,
32 to increase the rigidity of the edge of the cover plate 19, and these ears 31, 32 are pressed against the upper sides of the groove 8, respectively, so as to resist loads from above.

In the embodiment shown in FIG. 3, the configurations other than those described above are substantially the same as those in the embodiment shown in FIG. 2, so explanations thereof will be omitted.

It should be noted that, as is clear from the above description, the connecting portions of the segments are formed in the same manner not only at the bottoms of the segments but also on the inner and outer walls, and the backing 11 and cover plate 19 are also formed along the entire length of the connecting portions. It is set across.

However, the port 1 that connects the abutted rising parts 10
3 are arranged at appropriate intervals, and the support pieces 12 are also arranged at positions where the ports are attached.

As explained above, the connecting device for a prefabricated pool according to the present invention allows adjacent grooves that appear due to the connection of each segment to be easily closed with a single covering plate, and the closing can also be done by simply covering the grooves. Assembling the tank body is very simple since it is sufficient to install the plate into the groove.

Moreover, since it is extremely easy to disassemble, the tank body can be disassembled and made compact during the off-season, so it does not take up much space to store.

Furthermore, when assembling the tank, each segment can be lined up on a support surface such as the ground at the connection part, and the connection work can be performed from the surface side of the tank, so there is no need to stand the segments on their sides or fall over during the connection work. There is no need to do any work.

Of course, this also applies when disassembling, and the assembly and disassembly work is extremely easy.

In addition, since the cover plate has support legs that come into contact with the bottoms of the two grooves in the connecting part, since the support legs are deep inside the grooves, there is no risk of the cover plate being accidentally removed, and the plate part Since the load applied from above is supported by the supporting legs and the rising part that contacts the lower surface of the plate at its center, even if you step on this connecting part while the pool is in use, it will not bend easily and there will be no inconvenience in use. do not have.

In addition, in the above-mentioned embodiment, the tank body was shown to be composed of three segments, but in the present invention, the number of segments can be set as appropriate, and by using segments that divide the tank body vertically and horizontally, It can also be configured.
