Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a waterproof treatment structure for a large area such as a balcony or a veranda.

[Prior art and its problems]

Conventionally, waterproofing of a large area such as a balcony or a veranda is performed by laying a heat insulating material such as polyethylene foam on a wooden frame floor and then plywood for structural use on the heat insulating material.
After arranging a waterproof sheet and a fire prevention board in order, the FRP layer is applied by a wet application method to form a waterproof floor, and a protective wall along the periphery of the waterproof floor is erected on the skeleton floor. ing.

However, in the case of this prior art, the cold air transmitted from the waterproof floor due to the difference in atmosphere (outdoor and indoor) between the waterproof floor and the skeleton floor causes dew condensation on the inner surface of the skeleton floor, causing corrosion of the skeleton floor, resulting in durability. The applicant has already filed Japanese Utility Model Application No. Sho 62-166173 since the waterproof floor needs to be in a floating floor shape because of the deterioration of the waterproof floor.

In this prior art, a required floor panel formed of a waterproof material is fastened with a connector with the end faces mutually interposed with a sealing material therebetween to assemble and form a waterproof floor main body, and the waterproof floor main body is mounted on a skeleton floor by adjusting means. It has a structure in which it is supported in the form of a floating floor, and a protective wall is erected along the edge of the waterproof floor main body on the skeleton floor except for the edge of the house wall side having the entrance.

However, in this prior art, a stagnant air is gradually cooled by cold air transmitted from the waterproof floor main body because a sealed chamber in which air stagnates between the skeleton floor and the waterproof floor main body,
Due to the temperature difference between the stagnant air and the room, dew condensation occurs on the inner surface of the skeleton floor, and deterioration of durability is inevitable from a long-term perspective, and there is still a problem in preventing corrosion of the skeleton floor.

[Technical issues]

A technical object of the present invention is to prevent air from stagnating between a waterproof floor main body and a skeleton floor.

(Technical means)

The technical measures taken to achieve the above technical issues are:
A ventilation means for circulating into the space between the waterproof floor main body and the skeleton floor is provided.

[Action]

 The operation according to the technical means of the present invention is as follows.

Since the outside air (air) flows between the waterproof floor main body and the skeleton floor by the function of the ventilation means, the generation of dew condensation on the skeleton floor and the evaporation of the dew condensation are sequentially repeated by the action of the external air flow. Eliminate long-term adhesion.

〔The invention's effect〕

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

Since the long-term dew condensation on the bottom of the skeleton floor is eliminated and the skeleton floor is dried, the erosion of the skeleton floor can be prevented, and the influence on the life of the house can be minimized.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.
