Waterproof structure of pitched roof eave gutter and construction method of waterproof structure

Abstract

The invention discloses a waterproof structure of a pitched roof eave gutter. The waterproof structure comprises an inclined pitched roof and an eave gutter fixed to the outer side of the pitched roof. The surface of the eave gutter is coated with two layers of paint, wherein the bottom layer is formed by waterproof paint and is in direct contact with the concrete surface of the eave gutter, and the other layer is formed by weather-proof paint coating the upper layer of the waterproof paint. Polyurethane waterproofing paint serves as the waterproof paint, and the waterproof paint completely covers the upper surface of the eave gutter; and aliphatic polyurethane weather-proof waterproof paint serves as the weather-proof paint, and the weather-proof paint completely covers the upper surfaceof the waterproof paint. The waterproof structure of the pitched roof eave gutter has the advantages that the surface of the eave gutter is coated with one layer of polyurethane waterproofing paint, after the polyurethane waterproofing paint is set, the surface of the waterproof paint is coated with the weather-proof paint, the waterproof paint plays the role of waterproof sealing to the eave gutter, the weather-proof paint can relieve the damage of the environment to the waterproof paint and prolongs the service life of the waterproof paint, and compared with an existing eave gutter waterproof mode, the issues of additional arrangement of a protection layer and large self-load are avoided.

Description

technical field [0001] The invention relates to the field of house eaves waterproofing, in particular to the waterproof structure and construction method of sloping roof eaves. Background technique [0002] The gutter is the gutter beside the eaves, which collects rainwater through the long side and allows the rainwater to overflow to the outside along the gutter. The gutters are usually made of concrete or metal. Since the metal is easy to corrode and the welded joints in the assembly are prone to water leakage, the current gutter products are mostly made of concrete. For concrete gutters, there may be cracks and water leakage during long-term use, and if the gutters are not waterproofed in the early stage of construction, they will be damaged under the comprehensive damage of outdoor light, cold and heat, and wind and rain. , resulting in cracks or other damage, so that cracks or pits appear on the surface. When it rains, rainwater will accumulate in this position, causin...

Problems solved by technology

For concrete gutters, there may be cracks and water leakage during long-term use, and if the gutters are not waterproofed in the early stage of construction, they will be damaged under the comprehensive damage of outdoor light, cold and heat, and wind and rain. , resulting in cracks or other damage, resulting in cracks or pits on the surface. When it rains, rainwater will accumulate at this location, causing the cracks or pits to continue to grow, which will affect the future water collection performance of the gutter

[0003] In the existing construction projects, the construction method of the gutter is usually to apply a layer of paint or lay a layer of waterproof membrane, but these two methods have the following problems: for the method of applying a layer of paint, often It is necessary to cover a layer of concrete protective layer on its surface, the load is greatly increased, and additional expenses are added; and for the way of laying a layer of waterproof membrane, although the exposed waterproof membrane can be selected, there is no need to cover Concrete protective layer, but because the waterproof membrane itself is heavy, for gutters without any steel frame support, this setting method will increase the burden on the gutter wall. A large number of waterproof weak points affect the waterproof effect

In addition, the coil itself is thicker, and the overlapping during lapping eliminates the drainage slope of the gutter itself, which affects the drainage effect
