Description

[Detailed explanation of the invention] This invention relates to a device to make the bathroom completely waterproof and moisture-proof.
This is an attempt to solve the problem by physical means using a unique tarpaulin sheet, without using any materials.

In the conventional bathrooms of general buildings, consideration has naturally been given to waterproofing and moisture-proofing the bathrooms on the second floor, but the current situation is that, aside from moisture-proofing, almost no consideration has been given to waterproofing the bathrooms on the first floor. As a result, over a period of two to three years, the surrounding concrete foundations will oxidize, the reinforcing bars will rust, and the floor surface will become a breeding ground for harmful insects such as cockroaches, earthworms, and slugs due to its moderate temperature and humidity. There is. Currently, the Ministry of Construction is taking the lead in promoting and developing technology to maintain and improve buildings, and even in the private sector, a number of housing manufacturers are making 10-year warranties a selling point. However, unless the bathroom is completely waterproofed, this goal will most likely not be achieved.

In addition, the conventional waterproofing and moisture-proofing treatment for bathrooms on the second floor uses chemical bath additives as a means of adhering the waterproof sheet to the wall base, which is not only harmful to the human body, but also poses a fire safety problem. It is difficult to meet the construction schedule because the surface requires near-perfect dry conditions. Furthermore, since the construction must be done by a specialist, the construction cost increases, leading to higher costs.

The present invention was made in view of the conventional situation, and will be explained below with reference to the embodiments shown in the drawings. In Figures 1 and 2, studs 7, rough boards 8 A bottoming waterproof sheet 1 is stretched over the lower part of the wall base W made of etc., and its upper edge is folded inward to create a water return 1a.
, and the floor surface has a base mortar layer M on its upper surface.
The wall surface is covered with a side waterproof sheet 2, which has a number of mesh fasteners 3 arranged on the surface and integrally attached with waterproof banners 2a at appropriate intervals in the horizontal direction. Part is the bottoming waterproof sheet 1
The part of the sheet covered by the waterproof banner 2a is tacked 4 to the wall base W so as to hang down from the front side of the wall, and a lath net 5 is stretched over the entire surface of the sheet and secured with a net fastener 3. Further, a tile T is formed on the surface with a base mortar layer M interposed therebetween.

In addition, 9 in the drawing is a drainage port provided on the floor surface.

As described above, the present device does not use any chemical bath agents to stretch the tarpaulin sheet and uses tatker hammering, so there is no need to worry about toxicity or ignitability, and it can be easily installed even by non-specialists. In particular, since construction can be performed even when the construction surface is incompletely dry, there is no delay in the construction period, which leads to overall cost reductions.

In addition, from the waterproof and moisture-proof surface, water flaps 1a are formed on the upper edge of the bottoming sheet 1, and waterproof banners 2a are integrally attached to the side covering sheet 2 at appropriate intervals in the horizontal direction. Since the back sheet part covered by the waterproof curtain 2a is tacked 4 to the wall base W, the tacked part is covered by the waterproof curtain 2a to prevent water from seeping out from the part.

From the above, this proposal is truly beneficial as it achieves the intended purpose.
