BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for fixing a drainage lid installed in a drainage recess of a swimming pool laid with a waterproof sheet, that is, a drainage pit, a drainage basin, or a drainage recess. About.

[0002]

2. Description of the Related Art A conventional drainage lid fixing device for a swimming pool laid with a waterproof sheet is disclosed in, for example, Japanese Utility Model Publication No. 4-35470.
There is what was described in the issue.

As shown in FIG. 6 and FIG. 7, this conventional drainage lid fixing device for a waterproof sheet laid pool has a drainage lid fitted to an upper peripheral edge of a peripheral side wall (2a) of a drainage recess (2). A step (3) is formed, and a joining plate (5) fixed to the pool body (1) in a covered state from the horizontal surface (3a) of the step to the upper peripheral side of the drainage recess connected thereto. In a waterproof sheet laying pool in which a waterproof sheet (4) is laid by being joined to the joining plate, a pool having a vertical portion (21) and a horizontal portion (22) shown in FIG.
Or a plurality of mounting members (20),
1) is joined to and integrated with the upper waterproof sheet surface of the peripheral side wall of the drainage recess, and the horizontal portion (22) is connected to the drainage recess (2).
The drainage lid (10), which is provided in the drainage recess in a horizontal protruding arrangement inside and is fitted in the step (3), is located below the horizontal part (22). )
Are screwed and fixed to the through holes (23).

As shown in FIGS. 6 and 7, the screw fixing means includes a bolt (14) penetrated through the through hole (12) of the drain lid (10) in a state where the head is buried, and a mounting member horizontal portion. The flanged nut (1) fitted in the through hole (23) of (22)
The combination of 5) is used. That is, the nut (15) is screwed into the nut (15) by passing the bolt (14) through the through-hole (12) of the drain lid (10), so that the nut expands and deforms in the diametrical direction, and the nut (15) passes through the through-hole (23). Pull-out is prevented, so that the drain lid (10) and the mounting member (2)
0) is fixed so as to be detachably connected.

The above-mentioned flanged nut (15) has been formed of neoprene rubber having elasticity in order to expand and deform.

[0006]

In the above-mentioned conventional drain lid fixing device for a waterproof sheet-laying pool, the drain lid (10) is provided.
And the horizontal part (22) of the mounting member (20) are fixed to prevent unintentional removal of the drain lid (10) due to the mischief of the swimmer and to improve safety. However, there were the following problems.

That is, the flanged nut (15) is formed of neoprene rubber, and is immersed in pool water. There is a problem that the function as a nut is impaired.

[0008] The present invention solves the above-mentioned conventional problems, and disinfects the pool water by disposing the flanged cylindrical nut member of the screw fixing means for fixing the drain lid made of stainless steel. Waterproof sheet laying pool which is not corroded and deteriorated by water and can prevent seizure between the flanged cylindrical nut member and the bolt screwed into the flanged cylindrical nut member even if the flanged cylindrical nut member is made of stainless steel. It is an object of the present invention to provide a drainage lid fixing device.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a step portion for fitting a drainage lid is formed on an upper peripheral edge of a peripheral side wall of a drainage recess. ,
Waterproof sheet laying in which a joint plate fixed to the pool body is provided in a covered state from the horizontal surface of this step to the upper part of the peripheral wall of the drain recess connected thereto, and a waterproof sheet is laid on this joint plate A vertical section and a horizontal section provided on an upper waterproof sheet of a peripheral wall of the drain recess in the pool;
Or a plurality of mounting members, the vertical surfaces of which are joined and integrated, and the horizontal portion is provided in the drain recess so as to be horizontally protruded inside the drain recess, and the step portion In the drainage lid fixing device for a waterproof sheet laid pool, wherein the drainage lid installed in the fitted state is to be fixed to the horizontal portion located therebelow by screwing and fixing means, the screwing and fixing means is: A flanged cylindrical nut member made of stainless steel fitted and fixed in a through hole formed in a horizontal portion of the mounting member, and a bolt screwed into the flanged cylindrical nut member; The gist of the invention is that the nut member is provided with a short female screw portion into which the bolt is screwed.

According to this, since the flanged cylindrical nut member is made of stainless steel, the flanged cylindrical nut member is not corroded and deteriorated by a sterilizing agent or the like put into pool water.

Further, since the female screw portion on the inner side of the flanged cylindrical nut member has a short dimension, seizure between the stainless steel flanged cylindrical nut member and the bolt screwed into the member is prevented.

According to a second aspect of the present invention, a double nut is screwed into the male screw portion in a state where the flanged cylindrical nut member has a male screw portion formed on an outer periphery thereof and is fitted into a through hole of the mounting member. The gist is that they are combined and fixed.

According to this, since the double nut is screwed into the external thread portion on the outer periphery of the flanged cylindrical nut member, the flanged cylindrical nut member is securely fixed to the mounting member and is prevented from coming off.
