Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improvements in the structure of joints in assembled pools.

Recently, pools have been manufactured by combining segments made of fiber-reinforced plastic (hereinafter referred to as FRP), but in this structure, the problem is how to configure the joints. That is, the assembled pool needs to be stored compactly when not in use, and since it is repeatedly assembled and disassembled, it needs to be easy to operate and to be able to seal reliably. Conventionally, the flanges of each other were fixed with fixed nails, and
The structure is either glued and sealed with FRP, or a plate-shaped packing is sandwiched between the flange and fixed with fixed nails. These structures have a problem in that disassembly and assembly are extremely time consuming.

As a solution to this drawback, JP-A-57-
Publication No. 160502 proposes a structure in which a concave portion and a convex portion that face each other are formed on the flange surface of the joint portion, and a packing having a circular cross section is inserted into the concave portion. However, with this structure, the gasket tends to be twisted when inserted, and if the gasket is inserted in a twisted state, the gasket will shrink unevenly and the installation center of the gasket will shift, resulting in an incomplete seal. It has the disadvantage of becoming

The present invention has been made in order to eliminate these conventional drawbacks, and provides a joint structure that is easy to disassemble and assemble, and which can reliably achieve sealing.

That is, in each joint of an assembled pool formed by connecting a plurality of segments to each other, the end of the segment is formed with a flange orthogonal to the side wall and the bottom wall, and the flange surface of one segment is formed with a flange orthogonal to the side wall and the bottom wall. A recess is formed, and a protrusion corresponding to the recess is formed on the flange surface of the other segment to be joined to the recess, and a packing is inserted into the recess to press the protrusion into the recess through the packing. In the configuration for sealing, the opening of the recess is formed with an outwardly opening inclined surface, the packing is formed along the inner surface of the recess and expands outward along the shape of the recess at the opening of the recess, The protrusion has an inclined surface corresponding to the inclined surface of the opening of the recess, and a certain space is formed between the protrusion and the recess when the inclined surface of the recess and the inclined surface of the projection are aligned. A protrusion and a recess are formed on the surface.

Embodiments of the present invention will be described below with reference to the drawings. The pool 1 is made up of a plurality of segments 2 connected to each other, and each segment 2 has a bottom plate and a side plate.
It is integrally molded from FRP, and a flange 3 or 4 is formed at the end thereof to be perpendicular to the bottom plate and the side plate. The flanges 3 and 4 are formed in a single plane, with the flange 3 having a protrusion 5 and the flange 4 having a recess 6. The segment 2 may have a flange 3 formed at both ends thereof, and may be joined to a segment 2 formed with a flange 4 at both ends, or each segment 2 may be formed with a flange 3 at one end and a flange 4 at the other end. good.

Figures 3A and 3B show the cross-sectional shape of the joint;
As shown in B, the packing 7 is inserted into the recess 6, and the protrusion 5 of the segment to be joined is opposed to it, and as shown in B, the protrusion 5 is fitted into the recess 6 and the packing 7 is pressed. In this state, sealing is performed by tightening both flanges 3 and 4 with a clamp (not shown). The gasket 7 is formed in a shape as shown in FIG. 4A, that is, in a shape that extends outward along the inner surface of the recess 6 and along the recess on the opening side of the recess. Alternatively, a packing 8 having the above-mentioned outer shape with a hole 80 formed therein as shown in FIG. 4B, or a substantially triangular packing 9 as shown in FIG. 4C may be employed. In all of these cases, the outer shape is formed along the inner surface of the recess 6 into which the packing is inserted.

In the above shape, since the gasket matches the inner surface shape of the recess 6, there is no risk of twisting the gasket when it is inserted, and since the gasket is formed to expand outward on the opening side of the recess, the projection The center of the packing can be reliably pressed, and therefore sealing can be performed reliably. In addition, the work of inserting the gasket can be easily performed.

As explained above, the present invention includes forming a concave portion and a protrusion facing each other at the joint of each segment of an assembled pool, and disposing inside the concave portion a packing having a shape extending outward along the inner surface of the concave portion. The installation work is easy and sealing can be achieved reliably.
