Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is directed to a waterproof structure for parts occupying a large area such as balconies and verandas.

(Prior art and its problems) Conventionally, waterproofing of parts occupying a large area such as balconies and verandas was carried out by laying a heat insulating material such as polyethylene foam on the wooden frame floor, and then placing wood plywood, etc. on top of the heat insulating material. After sequentially arranging waterproof sheets and fireproof boards in a laminated manner, a waterproof floor is formed by applying an FRP layer using wet spraying, and a protective wall is further erected on the frame floor along the periphery of the waterproof floor. has been done.

However, in the case of this prior art, due to the difference in the atmosphere between the waterproof floor and the frame floor (outdoor and indoor), the cold air transmitted from the waterproof floor causes condensation on the inner surface of the frame floor, causing corrosion of the frame floor, resulting in poor durability. The applicant has already filed U.S. Pat. No. 62-166173 because it is necessary to make the waterproof floor floating.

This prior art involves assembling and forming a waterproof floor body by connecting the necessary panels molded from waterproof material with a connecting tool with their end faces interposed with a sealing material, and then attaching this waterproof floor body to the frame floor using adjustment means. It has a structure in which the waterproof floor is supported in the form of a floating floor, and a protective wall is erected along the edge of the main body of the waterproof floor, except for the edge on the house wall side where the entrance/exit part is located.

However, since this prior art creates a sealed Y in which air stagnates between the building frame floor and the waterproof floor body, the stagnant air is gradually cooled by the cold air transmitted from the waterproof floor body, and the stagnant air is gradually cooled down inside the room. From a long-term perspective, it is unavoidable that condensation forms on the inner surface of the building frame floor due to the temperature difference between the ground and the building block, leading to deterioration of durability, and there are still problems with soil that prevents corrosion of the building block floor.

[Technical issues]

The technical problem of the present invention is to prevent air from stagnation between the waterproof floor body and the frame floor.

[Technical means]

The technical means taken to achieve the above-mentioned technical problem was to provide ventilation means to prevent the flow from flowing into the space between the waterproof floor body and the frame floor.

[Effect]

The effects of the technical means of the present invention are as follows.

Due to the function of the ventilation means, outside air (air) flows in and flows between the waterproof floor body and the framework floor, and the action of the outside air flow causes condensation on the framework floor and evaporation of the condensation to occur repeatedly, so that condensation does not occur. Eliminates long-term build-up.

〔Effect of the invention〕

Since the present invention is constructed as described above, it has the following advantages.

Since the long term 41 condensation adhering to the underside of the building frame floor is eliminated and the building block floor is prevented from drying, IIg corrosion of the building frame floor can be prevented and the impact on the lifespan of the house can be minimized.
