Flashing durable structure at roof protruding structure and construction method

Abstract

The invention provides a flashing durable structure at a roof protruding structure, and relates to the technical field of building flashing structures. The flashing durable structure comprises a seepage-preventing and leveling layer arranged on the surfaces of a roof base layer and a vertical wall and used for seepage prevention and leveling, and a reinforcing net used for reinforcing the anti-cracking performance of the seepage-preventing and leveling layer is arranged at the corner of the seepage-preventing and leveling layer; and a flexible waterproof layer used for waterproofing and a polymer mortar anti-cracking layer are sequentially laid on the seepage-preventing and leveling layer and the reinforcing net in the direction away from a building body. The flashing structure in the scheme has the advantages of anti-cracking, seepage prevention and long service life.

Description

Technical field[0001]The invention relates to the technical field of building flooding structures, in particular to a flooding durable structure at a roof protruding structure and a construction method.Background technique[0002]During the construction of the building, a large number of reinforced concrete is used for construction. Usually, a vertical wall is set on the roof base on the top of the building. In order to reduce rainwater from entering the building, water is set between the roof base and the vertical wall to guide the flow of rainwater. The direction of the flooding structure.[0003]According to the existing related technology, the conventional method is to apply a layer of ordinary cement mortar to the flooded area and initially compact it with a wooden trowel, and then construct the waterproof coiled material or waterproof coating of the variety and thickness required by the design, and then apply the waterproof coiled material or The surface of the waterproof coating ...

AI Technical Summary

Problems solved by technology

[0004] The existing related technology has the following technical defects: the roof flashing structure formed by using this scheme is in the shape of a right angle or an obtuse angle due to irregular radians, and at the same time, due to the low tensile strength of the rigid body after the ordinary cement mortar is cured, the The delay, the flashing part gradually produces stress deformation cracks and damage in the alternating cold, hot, dry and wet environment in winter and summer, which leads to the common quality problems of cracking and leakage in the flashing part. On the one hand, it affects the normal use function of the project, and on the other hand, it increases maintenance cost
