Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for mounting a handrail in a swimming pool made of fiber-reinforced plastic.

[Prior art]

Conventionally, pools made of fiber-reinforced plastic (hereinafter referred to as FRP) have been proposed in order to make pools into units that can be produced in factories and assembled at construction sites. However, something like this
In FRP pools, it is usually necessary to attach handrails to the upper edge wall, which is formed integrally with the side wall and extends outward.

[Problem that the invention seeks to solve]

Attaching the handrail to the upper edge wall in this way can be done using a flange, etc. installed at the end of the handrail, but if a force is applied to the upper part of the handrail from the side, the thin plate-shaped upper edge wall will bend. There is a problem with the handrails being wobbly. The present invention aims to propose a specific handrail mounting structure that solves these problems in FRP pools.

[Means for solving problems]

For this reason, the handrail attachment structure for the fiber-reinforced plastic swimming pool according to the present invention is such that the handrail 18 is attached to the thin plate-shaped upper edge wall 12 that is integrally formed at the upper end of the side wall 11 constituting the pool and extends outward. 10, the side wall 11 is attached to the upper edge wall 12.
A cylindrical body 20 having an opening 17 slightly spaced further outward and having at least a lower end portion 20c which becomes smaller in diameter toward the lower side is disposed in the vertical direction, and the upper end 20a of this cylindrical body is connected to the upper end of the cylindrical body 20. Opening 1 in edge wall 12
A baffle member 21 made of fiber-reinforced plastic is fixed to the lower side of the portion corresponding to 7, and its lower part is positioned slightly outward from the side wall 11.
The lower end 18a of the handrail 18, which is fixed to the same side wall and fitted into the cylindrical body 20 through the opening 17, is fitted and supported by the tapered part of the cylindrical body 20, and the upper end of the handrail 18 is A portion of the edge wall 12 corresponding to the opening 17 is supported by being brought into pressure contact with the inner peripheral edge of the opening 17 by a pressing member 33 disposed near the opening 17.

〔Effect of the invention〕

According to the present invention, the handrail is fitted into a cylindrical body whose upper and lower parts are fixed to the upper edge wall and the side wall,
Since it is supported at two places, the lower end and the part corresponding to the opening in the upper edge wall, it can be firmly fixed to the thin plate-shaped upper edge wall of the fiber reinforced plastic pool without wobbling, and the tube The lower part of the cylindrical body was positioned slightly outward from the side wall and fixed to the same side wall with a baffle member, so even if there were some irregularities on the back side of the side wall, there was no need to make any special corrections, and the cylindrical body could be accurately shaped. Can be installed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial perspective view of an FRP pool 10 to which the present invention is applied. This FRP pool 1
0 is multiple FRP with predetermined size and shape
side walls 11 to 11 made of FRP, thin plate-like upper edge walls 12 to 12 made of FRP integrally formed on the upper edge of each of these side walls 11 and extending to the side walls, and bottom plates 13 to 11 made of FRP.
13, and this pool 10 is formed by joining these together and bridging this joint. A recess 14 is formed in the center of each upper edge wall 12, and these recesses 14 form a pool 10 when each upper edge wall 12 is joined.
This serves as an overflow groove surrounding the periphery of the groove, and a slat board 15 is placed on top of the overflow groove. Further, a step 16 is integrally molded on the side wall 11 located in the center of the figure, and in this case, the entire step 16 is slightly retracted from the surface of the side wall 11, as shown in FIG. be. Further, on the upper edge wall 12 located above the left and right sides of the step 16, a first
Openings 17-17 are formed as shown in FIG. 3 and FIG. These openings 17 are approximately inverted U-shaped handrails 18 and 1 formed by bending metal pipes.
The size corresponds to the outer diameter of 8. Note that the reference numeral 16a in FIGS. 1 and 2 indicates a cover plate made of FRP. This cover plate 16a has the same size as the entire step 16, and when fixed to the front surface of the step 16, It forms the same surface as the side wall 11,
For example, this is to prevent step 16 from getting in the way when a large number of people practice kitkturn.

Further, on the lower side of the portion of the upper edge wall 12 corresponding to each opening 17, as shown in FIGS. 3 and 4,
FRP cylindrical bodies 20 to 20 are arranged and fixed in the vertical direction, respectively. Each cylindrical body 20 is a bottomed cylindrical body that is tapered so that its inner diameter becomes smaller from the upper end 20a to the lower end 20b,
A tapered portion 20c whose upper end 20a has an opening corresponding to the opening 17 of the upper edge wall 12 and is located at its lower end.
The inner diameter of the handrail 18 is smaller than the outer diameter of the lower end 18a of the handrail 18. Moreover, each cylindrical body 20 located on the side wall 11 side is connected to the side wall 11 as shown in FIG.
It is located slightly outwardly from the periphery, and is firmly fixed to the lower surface of the upper edge wall 12 and the back surface of the side wall 11 by an FRP blind member 21 attached to its outer periphery. In addition, since each cylindrical body 20 and the side wall 11 are separated by a predetermined distance, even if there are irregularities on the outer peripheral surface of each cylindrical body 20 and the back surface of the side wall 11, the positioning can be performed without being hindered by the irregularities. In this case, a filler such as honeycomb is filled between each cylindrical portion 20 and the side wall 11 as necessary. The cylindrical body 20 and the side wall 11 are fixed at least at the lower part of the cylindrical body 20. On the other hand, each of the outer cylindrical bodies 20 has its lower end fixed to the lower surface of the upper edge wall 12 forming the recess 14 . (See FIG. 2) Furthermore, on the upper surface of the upper edge wall 12 corresponding to each opening 17, as shown in FIGS.
has been done. This lip member 30 is substantially part of the upper edge wall 12 and has an opening 31 for each handrail 18.
The upper edge wall 12 is formed slightly larger than the outer diameter of the upper edge wall 12.
The tip 33a of the push bolt, which is the push member 33, protrudes into the opening 31. This push bolt 33 is attached to the edge member 30
It is attached so that it can be screwed forward and backward.

The FRP pool 10 described above is placed on a foundation with sand as a buffer material interposed therebetween, and is placed on a foundation with earth mounded below each of its upper edge walls 12.

In the FRP pool 10 described above, in order to erect the handrails 18, 18 on the upper edge wall 12, first, the tips 33a of each push bolt 33 should not protrude into each opening 31, and each The lower end 18a of the handrail 18 is inserted into each cylindrical body 20 through each opening 31, 17. Then, the lower end 18a of each handrail 18 fits into the tapered portion 20c of each cylindrical body 20 and is securely supported. In this case, each handrail 1
8 from above, the lower end 18a of each handrail 18 and the tapered portion 20c will fit better. Furthermore, each push bolt 33 is screwed forward, and each handrail 18 is attached to each edge member 30 by its tip 33a.
And if pressed against the upper edge wall 12 side, each handrail 18
is each opening 1 at the part corresponding to each opening 17, 31.
It is securely fixed to the upper edge wall 12 by firmly pressing against the inner peripheral edges of 7 and 31. That is, each handrail 18
is supported at two locations corresponding to its lower end 18a and each opening 17, 31, and is securely fixed to the upper edge wall 12 without wobbling.

In this embodiment, since each of the cylindrical bodies 20 has a bottom, the upper end 20 of each cylindrical body 20 is
Even if water enters from a, it will not come out from now on, and will not have an adverse effect on the pool 10, such as causing the earth mound or sand to flow. Also,
Each cylindrical body 20 has an inner diameter that decreases over its entire length from the upper end 20a to the lower end 20b, so when molding with FRP, there is no need to create a draft angle and it is easy to take out from the mold. It can be done easily.

In the above embodiment, an example was described in which a push bolt was used as the pressing member 33 for pressing the portion of each handrail 18 corresponding to the opening 17 against the inner peripheral edge of the opening 17. The support may be achieved by driving a wedge into the opening 17 into which the handrail 18 is inserted.
Further, an example has been described in which the inner diameter of each cylindrical body 20 is gradually decreased from the upper end 20a to the lower end 20b to form the tapered portion 20c.
The tapered portion may be provided only in the portion of each cylindrical body 20 corresponding to the lower end 18a of the handrail 18.
