Parapet wall crown rigid waterproof system

Abstract

The invention relates to a parapet wall crown rigid waterproof system, comprising a parapet wall crown outer flashing piece, a parapet wall crown inner flashing piece, a supporting conversion piece, an outer wall board, an inner wall board, a foam plug and a parapet wall crown purline, wherein the outer flashing piece is arranged above the supporting conversion piece, the left end of the inner flashing piece is arranged inside the right end of the supporting conversion piece, and the supporting conversion piece is fixed on the upper surface of the parapet wall crown purline. In the invention,the shapes of the inner and outer flashing pieces at the parapet wall crown are changed, and the supporting conversion piece used for connecting the inner and outer flashing pieces is additionally arranged to connect the inner and outer flashing pieces, thus the connection by cement in the prior art is changed into rigid waterproof connection by virtue of the supporting conversion piece. The system provided by the invention is simple in structure, and no cement is arranged in the whole system, thus the parapet wall crow has the rigid waterproof function, and the problem that water leakage is caused by ageing of the cement at the joint is thoroughly solved.

Description

Technical field: [0001] The invention relates to a rigid waterproof system for the top of a parapet wall of a building, in particular to a rigid waterproof system applied in steel structures and light steel color plate buildings, which is composed of an outer flashing part, an inner flashing part and a support conversion part of the parapet top Rigid waterproof system. Background technique: [0002] In the steel structure and light steel color plate building structure, there is generally the existence of the architectural functional element of the wall parapet. The parapet is often located at the highest point of the building and is the top of the building's exterior wall. Its aesthetics and waterproof requirements are extremely important. , and the roof leakage phenomenon of a large number of engineering examples in the past also fully shows that the node at the top of the parapet wall often suffers from water leakage. The prior art parapet top connection node such as fig...

AI Technical Summary

Problems solved by technology

The sealant or self-adhesive putty is fixed on the top of the above-mentioned parapet after the connection, so when the sealant or self-adhesive putty ages, this place often becomes a hidden danger of water leakage, although the technicians in the industry are constantly studying to improve the resistance of the sealant Aging, but the sealing effect can only last for 5-8 years at most, while the life of rigid buildings can reach 50-70 years, so it is impossible to achieve the same lifespan of the sealant as the building; The water plate 1' and the inner flashing plate 2' are processed as a whole, and the expanded size after their combination often exceeds 1200mm, which cannot meet the standard size of the color-coated steel plate in my country, resulting in a large number of splicing seams added in the length direction of the flashing parts , and there must be sealing glue at the joints, which is also easy to form a hidden danger of water leakage. Therefore, the waterproofing of the parapet top in the prior art is still an unsolvable problem.
