Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a packing for joining assembled pools.

Recently, pools have been manufactured by combining segments made of fiber reinforced plastics (hereinafter referred to as FRP), but in this structure, the problem is how to configure the joints. J.

That is, the assembled pool needs to be stored in a container when not in use, and since assembly and disassembly are repeated, it is necessary to be able to perform this work easily and to be able to seal it reliably. Conventionally, a structure has been adopted in which the flanges are fastened to each other with fixed nails and sealed with FRP adhesive, or a plate-shaped packing is sandwiched between the flange parts 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, Japanese Patent Application Laid-Open No. 57-1605
No. 02 proposes a structure in which gaskets having a circular cross section are inserted into the four parts facing the flange surface of the joint and the convex part TfLIi and the slot 11. However, with this structure, twisting tends to occur when inserting the packing, and if the packing is inserted in a twisted state, the packing will shrink unevenly and the installation center of the packing will shift, resulting in an uneven seal. It has the disadvantage of being complete.

The present invention has been made in order to eliminate these conventional drawbacks, and provides a packing 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 perpendicular to the side wall and the bottom wall, and the seven flange of one segment is A recess is formed in the segment, 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 gasket is inserted into the recess and presses the protrusion into the recess through the gasket. In configurations in which sealing is performed by
The gasket is formed along the inner surface of the recess and is formed to expand outward along the shape of the four openings at the four openings.

Embodiments of the present invention will be described below with reference to the drawings. The pool 1 is composed of a plurality of segments 2 connected to each other, each segment 2 has a bottom plate and a side plate integrally molded from FRP, and seven langes 3 or 4 are formed at the ends thereof to be perpendicular to the bottom plate and the side plate. There is. The 7 flange 3 and 4 are formed in a single plane, with the 7 flange 3 having a protrusion 5 and the 7 flange 4 having a quadrant 6. segment 2
may be formed with 7 flanges 3 at both ends thereof and may be joined to a segment 2 having flanges 4 formed 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. .

Press. In this state, both 7
Seal is achieved by tightening the lunge 3.4. The gasket 7 is formed in a shape as shown in FIG. 4(A), that is, in a shape that extends along the inner surface of the recess 6 and extends outward along the recess on the opening side of the recess. In addition, Fig. 4 (B
It is also possible to adopt a packing 8 having an upwardly-shaped outer shape with a hole 80 as shown in FIG. 4(C), or a substantially triangular packing 9 as shown in FIG. In all of these cases, the outer shape is formed along the inner surface of the four parts 6 into which the packing is inserted.

In the above shape, since the gasket matches the inner surface shape of the four parts 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 gasket does not fit into the protrusion. J: The center of the repacking 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. It is designed to be easy to install and securely seal.

Claims (1)

[Claims] 1. At each joint of an assembled pool formed by connecting a plurality of segments to each other, a flange perpendicular to the side wall and bottom wall is formed at the end of the segment, and four parts are formed on the flange surface of one segment. A protrusion corresponding to the recess is formed on the flange surface of the other segment that is joined to the recess, and a seal is inserted into the recess to suppress the protrusion into the recess through the seal, thereby creating a seal. Paragraph 4: The seal for joining an assembled swimming pool is characterized in that the ring is formed along the inner surface of the recess and extends outward along the shape of the four parts at the opening of the recess.
