Description

Waterproof structure using air vent sheet and waterproof method

The present invention relates to a waterproof structure and a waterproof method using a degassing sheet, and more particularly, by using the degassing sheet to discharge the water vapor between the waterproof bottom surface and the degassing sheet to obtain excellent waterproof construction results It relates to a waterproof structure and a waterproof method using.

In general, waterproofing is applied to roofs or roofs to prevent rainwater penetration and leakage in various types of buildings such as apartment buildings, shopping mall buildings, and single-family home buildings.

These waterproof structures and construction methods have been improved and developed in various forms, and recently, with the development of the chemical industry, various waterproof materials of excellent physical properties have been developed.

However, despite the improvement of the waterproofing material, the proper waterproof structure and the waterproofing method have not been improved, so that defects are frequently generated for the waterproofing work, resulting in a problem of requiring a separate maintenance cost and a maintenance period.

1 is a block diagram showing a conventional waterproof structure, Figure 2 is a block diagram showing a broken state of the conventional waterproof structure.

As shown in Fig. 1, in the conventional waterproof structure, in the asphalt waterproofing, the improved asphalt sheet waterproofing, and the waterproofing of the coating film which are generally used, the waterproofing bottom surface 1 is cleanly arranged first, and A primer (primer) is applied to the upper portion, and the waterproof layer 2, the waterproof protective mortar 3, the expansion joint 7 and the pressing layer 4 are sequentially installed thereon.

According to the conventional waterproof structure, the physical properties of the waterproof layer (2) is difficult to properly exhibit the behavior of the concrete structure, and defects frequently occur due to fatigue accumulation due to the water vapor pressure continuously generated in the lower portion of the waterproof layer (2). In addition, since the waterproof structure is sealed by the pressing layer 4, there is a problem that it is very difficult to dismantle and repair the pressing layer (4).

In particular, the conventional waterproof structure is a structure in which the waterproof bottom surface 1 and the waterproof layer 2 are in close contact with each other, so that the gas present in the waterproof bottom surface 1 cannot be discharged, and thus the gas pressure can be discharged. There is no outlet.

Therefore, the thickness of the waterproofing layer 2 is lifted by the change of the latent number existing between the waterproofing bottom surface 1 and the waterproofing layer 2 and the gas pressure rising from the lower layer, and at the same time, the thickness becomes thinner. There was a problem that the life of the waterproof layer (2) is shortened.

In addition, deflection of the waterproof layer 2 occurs because the waterproof layer 2 at the end of the parapet is not completely fixed. Therefore, water is accumulated in the drooping portion of the waterproof layer 2, and the water causes a leak, and at the same time, the durability of the waterproof layer 2 is lowered, causing a breakage of the waterproof layer 2.

As shown in FIG. 2, in the case of the exposed waterproof structure, the temperature change is considerable according to the external temperature, and when the pressing layer 4 is present, the temperature of the waterproof layer 2 is further increased.
