Description

TECHNICAL FIELD The present invention relates to a simple stationary pool in which a plurality of segments are assembled.

(Prior Art) Conventionally, a simple stationary pool used in kindergartens and the like is assembled and installed only when it is used in the summer, and it is disassembled at other times and stored in a reduced bulk state. This assembling and disassembling work is very troublesome in the conventional structure. This is because a large number of bolts must be tightened to prevent the joints between the segments that make up the pool from leaking.Especially, the joints at the bottom of the pool have a complicated structure that makes bolting difficult, which is extremely troublesome. It was hanging.

(Object of the Invention) The present invention has been made in order to solve the above-mentioned conventional drawbacks, and eliminates the need for bolting the bottom of the pool, thereby facilitating the assembly. It provides a stationary pool.

(Structure of the Invention) In the present invention, in a pool in which a plurality of segments are connected, the segments at both ends are composed of a bottom plate, both side plates and end side plates connecting the both side plates, and the middle segment is the bottom plate. And both side plates are formed in a substantially U shape, and outwardly projecting flanges are formed continuously on the bottom plate and both side plates at the end faces of each segment, and the flange faces are formed in a single plane. The ends of the segments and the flanges on one side of each middle segment are bent outwards at their tips approximately at right angles to the faces of the flanges, and are joined to one of the faces of the flanges of the bottom plates that are joined to each other between the segments. Is locally formed with a recess extending toward both side plates, and the other is provided with a protrusion to be fitted into the recess, and the flange in the region where the recess or the protrusion is not formed is formed. A reinforcing member is provided on the back side of the base plate to connect the flange and the lower surface of the bottom plate to increase the rigidity of the flange, and a reinforcing member is attached to the lower surface of the bottom plate. The pool is configured to be supported on the base, and a plurality of bolt holes are formed in the flanges of both side plates of each segment so as to face each other. At least two of the bolt holes are formed in the side plates and the bottom plate. Are formed at the intersections of the flanges of the respective segments, the flanges of the segments are opposed to each other, and the bolt holes are pierced through packings extending over the entire flange along the flange surface provided on the upper side of the recess and the protrusion. The flange is tightened with a bolt.

(Embodiment) In FIG. 2, a pool 10 is assembled by joining a segment 1 made of FRP and a segment 2 at both ends thereof in a watertight structure. Steps 3 and 4 used when the pool goes in and out are formed inside and outside one of the segments 2 at both ends. In this embodiment, two middle segments 1 are used, but this number may be set arbitrarily according to the size of the pool.

As shown in FIGS. 1, 3, and 4, the middle segment 1 is formed in a substantially U-shape by the bottom plate 5 and the side plates 6, and the upper ends of the side plates 6 form a substantially horizontal plane. The edge portion 7 is formed. Each of the end faces of the segment 1 is formed with a flange 8 of a side plate and a flange 9 of a bottom plate which project outward (in a direction perpendicular to the inner surface of the pool). The flange 8 and the flange 9 form a single plane. There is. A pair of upper and lower bolt holes 80 are formed in the flanges 8 on both side plates of the segment 1 so as to face each other. As shown in FIGS. 5 to 8, the flange 9 on one side of the segment 1 has a bent portion 91 formed by bending the tip end portion thereof substantially at right angles to the surface of the flange. Further, a concave portion 92 is formed in a part of the flange 9, and a protruding portion 90 formed by bending the tip end portion of the flange 9 is formed in the flange 9 on the opposite side to the position facing the concave portion 92. .

A reinforcing member 50 including a core material 51 made of foam and an outer skin 52 is attached to the lower side of the bottom plate 5. The reinforcing member 50 and the bent portion 91 of the flange make the segment 1 on an appropriate base. It is configured to be supported. This reinforcing member 50
In the portion where the concave portion 92 or the protruding portion 90 is not formed, the inside of the flange 9 is also formed in a triangular shape in cross section to increase the rigidity of the flange 9.

The structure of the end segment 2 is basically the same as that of the middle segment 1, but the bottom plate 5 and both side plates 6 are the end side plates 16.
The difference is that they are connected to each other. The respective segments 1 and 2 having such a structure are integrally formed by FRP molding.

In the above structure, the flanges 8 and 9 of the respective segments are opposed to each other, and the flanges 8 are tightened by bolts (not shown) which penetrate the bolt holes 80 through the packing 11 extending over the entire flanges. And segment 2 are joined. This joining work may be performed only on the flange 8 of the side plate 6 of the segment, and need not be performed on the flange 9 at the bottom. Since the bottom portion is reinforced by the flange bent at a right angle from the bottom plate 5 and the bent portion of the flange to have sufficient rigidity, the entire bottom portion can be sealed by tightening with bolts at both ends. You can As described above, since it is not necessary to tighten the bolts on the bottom portion and the assembly is performed by tightening only the flanges on the side portions, the work is easy and the assembly can be performed quickly.

(Effects of the Invention) As described above, according to the present invention, flanges having excellent rigidity are formed at both ends of the segment forming the pool, and the entire seal is achieved by the bolts at the flanges on both sides. Since the work of tightening the bolt at the bottom is unnecessary, the assembling work can be performed easily and quickly.
