Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a 2 × 4
Regarding the underfloor inspection port of a waterproof pan in a system bathroom installed in a (two-by-four) structure house, etc., particularly when applying a waterproof treatment by covering the underfloor inspection port formed in the waterproof pan body with a lid. In addition, the workability is improved, and the waterproof property is improved over a long period of time.

[0002]

2. Description of the Related Art For example, when a system bathroom is installed in a 2 × 4 (two-by-four) structure house or the like, since the building has a wooden frame structure, the space formed between the pillars is a wall panel. There is no space between the side wall of the bathroom and the skeleton wall of the building for installing piping systems such as water supply pipes, hot water supply pipes, and drain pipes. The waterproof pan body installed above is floated and supported by height-adjustable supporting legs to form a space between the indoor floor of the bathroom and the bottom surface of the waterproof pan body, and this space is used to supply water. At present, pipes, hot water pipes, drain pipes, and the like are provided.

[0003] Therefore, conventionally, after installing and installing the waterproof pan on the indoor floor of the bathroom, a water supply pipe and a hot water supply pipe which are piped in the space between the indoor floor of the bathroom and the bottom of the waterproof pan body. As shown in FIG. 5, for example, in order to enable maintenance / inspection of a piping system such as a drainage pipe and a drainage pipe, an inner bottom surface d of a bathtub mounting part c adjacent to a washing place b of a waterproof pan main body a is provided under the floor. An inspection port e is formed in advance.

[0004] As shown in FIG.
Normally, the peripheral edge f is formed to be one step lower than the inner bottom surface d of the bathtub mounting part c, and the flange peripheral edge i of the lid h is mounted on the stepped surface g, thereby mounting the bathtub. The lid is covered substantially flush with the inner bottom surface d of the portion c, and is waterproofed to prevent water leakage below the floor.

[0005]

However, in the waterproofing treatment of the waterproof pan having the conventional structure described above, as shown in FIG. 6, the stepped surface g of the underfloor inspection port peripheral edge f and the flange peripheral edge i of the lid h are used. The cover h is fixed and subjected to a primary waterproofing process by interposing a waterproof double-sided adhesive tape j between the cover h and the gap formed in the flange peripheral portion i of the cover h by a silicone seal k. Due to the double waterproof structure that is subjected to the next waterproofing process, it takes time for the silicon to solidify, which is not only inferior to the workability at the site, but also may forget the silicon sealing.

[0006] In addition, the peripheral edge of the lid is easily stained due to stickiness of the scaffold at the time of construction work by silicon sealing, so that the aesthetic appearance after the construction processing is poor. Because of deterioration and easy cutting, a sufficient waterproof effect cannot be maintained for a long period of time.

[0007] An object of the present invention is to provide a waterproof pan which is capable of improving the workability and improving the waterproofness over a long period of time when covering the underfloor inspection port with a lid and performing waterproofing. An object of the present invention is to provide an underfloor access port structure.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a waterproof pan which is provided with an underfloor inspection opening formed in a waterproof pan body with a lid and subjected to a waterproof treatment. In the underfloor inspection port structure, the upper surface of the lid is covered and adhered with a waterproof sheet wider than the outer dimensions of the underfloor inspection port, and an excess peripheral portion of the waterproof sheet protruding from the underfloor inspection port is removed. It is characterized by being stuck to the waterproof pan main body side.
