Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of an attachment device for a course rope hook in an assembled pool made of FRP.

(Prior art) Conventionally, as a mounting device for a course rope hook for an assembled pool made of FRP, a device was developed in the 1980s as shown in Fig. 4.
The one published in Publication No. 37400 is known.

In this prior art, a recessed part 100' is provided around the opening of an attachment port 100 opened in a pool side wall a, and a hooking fitting 102 for a course rope hook 101 is provided inside.
The flange portion 103' of the flange case 103 having
is accommodated in the recessed portion 100' and secured with bolts and nuts 104 and 105.

(Problem to be solved by the invention) However, in the above-mentioned conventional technology, the tension force of the course rope hook 101 is
Since the water is concentrated in the bolts 105, the bolts 104 are likely to loosen or buckle, which may lead to water leakage.

Therefore, the side walls of the pool itself were made thicker and
Similar to the concrete pool of Publication No. 40-34421, it is proposed to bury a cylindrical body with an internal screw for fitting the hook within its wall thickness, but it is only intended to strengthen the attachment part of the course rope hook. However, if the pool side walls themselves had to be made thicker, the overall weight would increase, which is undesirable and goes against the original purpose of FRP pools, which is to reduce the weight.

The present invention was devised in view of the problems of the prior art, and its purpose is to integrate it with the side wall of the pool without using mounting members such as bolts and nuts. The goal is to maintain the weight of the pool while solidifying its integration.

(Means for Solving the Problems) The technical means of the present invention to achieve the above object is to provide a threaded hole for attaching a hook at one end and a flange protruding from the other end. of
A mounting bracket that communicates with a hook insertion hole provided on the FRP side wall of the pool from the back of the side wall, and an FRP fixing member that fills the space between the flange of the mounting bracket and the back of the front side wall to fix the mounting bracket. , a lining material made of FRP is applied to the side and rear surface of the flange of the mounting bracket to cover the flange of the mounting bracket and the fixing member, and a hole is drilled in the flange of the mounting bracket, and the fixing member and The lining material is bonded and fixed.

(Function) By using the above technical means, the connection between the FRP pool side wall, the flange of the mounting bracket and the pool side wall is achieved.
The fixing member made of FRP and the lining material made of FRP that covers all of them from the back are firmly fixed due to the good adhesion between the same materials. Furthermore, both FRP layers bordering the flange of the mounting bracket are bonded and fixed through the holes drilled in the flange, thereby firmly fixing the mounting bracket.

In other words, when a force is applied to push the hook toward the side wall of the pool, the FRP lining material that covers all of the flange of the mounting bracket, the FRP fixing member between the flange and the side wall, and the back of the side wall supports the hook. If a pulling force is applied to the hook from the course rope, the gap between the flange of the mounting bracket and the pool side wall
The FRP fixing member supports the hook, and if force is applied to rotate the mounting bracket when replacing the hook, the
The FRP fixing member and the FRP lining material are bonded and fixed to each other to prevent rotation of the mounting bracket.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The installation device for the course rope hook of the present invention consists of a mounting bracket 1, a fixing member 2, and a lining material 3. Large diameter portions 1b are connected to small diameter portions 1a that fit into hook 9 insertion ports 6a opened corresponding to the number of courses to be subdivided at desired intervals, and the large diameter portions 1b
It is made of metal and has a protruding flange 4 with an injection hole 4a formed at its rear end, and the tip of the small diameter portion 1a is fitted into the insertion port 6a, and a screw hole 1a for attaching an internal hook is formed. ' and the insertion port 6a are positioned so that they communicate with each other on the back side of the pool side wall 6.

In this embodiment, the fixing member 2 is arranged between the flange 4 and the side wall 6 by covering the periphery of the flange 4 with a cover (not shown) to firmly fix the positioned mounting bracket 1. The space 5 to be formed is filled with an FRP casting resin (such as unsaturated polyester resin mixed with glass fiber) filled through the injection hole 4a opened in the flange 4, and the hook of the mounting bracket 1 is Screw hole 1 for mounting
The entire structure except a' is buried and fixed to the back side of the pool side wall 6 made of FRP.

The lining material 3 is made of FRP and is applied to the back surface of the pool side wall 6, covering the fixing member 2 and the flange 4 after the cover is demolded.

Therefore, when the FRP is applied to the lining material 3, it flows into the injection hole 4a formed in the flange 4 of the mounting bracket 1, thereby forming a joint 3a between the fixing member 2 and the lining material 3. Both the FRP layers of the fixing member 2 and the lining material 3 with the flange 4 of the mounting bracket 1 as a border are bonded and fixed via the injection hole 4a of the flange 4, and the three members of the mounting bracket 1, the fixing member 2, and the lining material 3 are bonded together. bond is strengthened.

In this embodiment, a sealing material 7 is provided to seal the hook insertion openings 6a when the course rope is not used (FIG. 2).

The filler 7 includes a screw shaft portion 7a that is inserted through the insertion port 6a and is removably screwed into the screw hole 1a' for attaching the hook, and a screw shaft portion 7a that is connected to the screw shaft portion 7a and is inserted into the screw hole 1a' for attaching the hook. It consists of a lid part 7c which has small holes 8, 8 which have the same diameter as the mouth 6a and are symmetrical with respect to the center point on the head surface 7b.A suitable jig is inserted into the small holes 8, 8 and rotated. The shaft part 7a is removably screwed together so that the head surface 7b of the lid part 7c is flush with the inner surface of the pool side wall 6, and the screw hole 1a' for attaching the hook and the insertion port 6a are sealed.

Further, the head surface 7b of the filler 7 has the same color and the same rough surface so as to be continuous with the inner surface of the pool side wall 6.

Therefore, if the hook 9 is removed and the sealing material 7 is screwed together, it becomes part of the pool side wall 6, so the pool used for practice can be divided into 10 or more courses instead of the usual 8 courses, for example, for competitions or competitions. When used as an official race pool, there will be no trace of unnecessary hooks 9 for the course rope, and the protruding portion of the hooks 9 will change to the side walls 6 of the pool, so hands and fingers will get caught during swimming. This also complies with the rules for certified pools.

(Effects of the invention) This invention can be applied to an assembled pool made of FRP.
In addition to connecting the screw hole of the mounting bracket to the hook insertion hole provided on the FRP pool side wall,
The course rope hook is made by fixing the mounting bracket to the back side of the pool side wall by burying it with an FRP fixing member, and then applying an FRP lining material to the back side of the pool side wall to cover the mounting bracket and the fixing member. Because of the installation device, the FRP pool side wall, FRP fixing member, and FRP lining material are firmly fixed due to the good adhesion of the same materials, and it does not require the use of conventional mounting members such as bolts and nuts. It can be integrated without using any.

In addition, if a force is applied to push the hook toward the side wall of the pool, the FRP lining material that covers the flange of the mounting bracket, the fixing member, and the back of the side wall will support this and pull the hook from the course rope. If force is applied, the FRP fixing member between the flange of the mounting bracket and the side wall will support this.
Moreover, since both the FRP layers of the fixing member and the lining material bordering on the flange of the mounting bracket are bonded and fixed through holes drilled in the flange, the hook cannot be rotated to the mounting bracket when replacing the hook. Even if a force is applied to the mounting bracket, the joint between the two FRP layers through the holes in the flange acts to prevent the mounting bracket from rotating, ensuring that it is firmly fixed no matter how much force is applied to the mounting bracket. As a result, the hook mounting bracket can be firmly attached without making the pool side wall itself thick, which is very useful as the hook mounting part can be strengthened and the weight of the FRP pool can be maintained.
