Description

Earthquake-resistant waterproof structure {EARTHQUAKE RESISTANT TYPE WATERPROOF STRUCTURE}

The present invention relates to a shockproof waterproof structure.

Waterproofing method is divided into sheet waterproofing method, coating film waterproofing method, and composite waterproofing method.

Sheet waterproofing method is a method of forming a waterproof layer by attaching or fusion bonding the factory-produced waterproof sheet. Sheet waterproofing method has the advantages of uniform thickness of the waterproof layer according to the standardization of the product, excellent finish, and quick construction. However, the defect occurrence rate is high at the joints between the sheets, difficult construction work is difficult, and peeling or sagging may occur due to the temperature change in the wall or the parapet. In addition, the sheet material is sensitive to temperature and is affected by the season, and there is a disadvantage in that the waterproof performance is degraded due to fracture due to partial bonding failure and insufficient stability.

Coating waterproofing method is a method of forming a waterproof film by applying a plurality of times to the base surface of the liquid waterproof material. According to the waterproof coating method, it is easy to transport the material, it is possible to form a waterproof layer only by applying a liquid material there is an advantage that the construction is easy. However, there is a disadvantage in that the thickness of the coating film is not uniform due to the irregularities of the concrete base surface, and part of the waterproofing membrane swells due to water vapor pressure, which is generally caused by insufficient curing of the base surface after concrete placement, As a result, pinholes may occur and tearing may occur in winter.

On the other hand, in order to supplement the disadvantages of the sheet waterproof method and the coating film waterproof method has been introduced various types of composite waterproof method. For example, Korean Patent Registration No. 238994 and Korean Patent Registration No. 1015120 disclose a composite waterproof structure and a composite waterproof method.
