Fabricated external wallboard waterproof system and construction method thereof

Abstract

The invention discloses a fabricated external wallboard waterproof system. The fabricated external wallboard waterproof system comprises external wallboards, wherein the top faces of the external wallboards are in a three-step shape and comprise first drainage slopes, second drainage planes and third drainage slopes from outside to inside, and the bottom faces of the external wallboards are in a three-step shape coupled with the top faces of the external wallboards; and grooves are formed in one sides of the external wallboards, and protruding blocks coupled with the grooves are arranged on the other sides of the external wallboards. A construction method of the fabricated external wallboard waterproof system comprises the steps of external wallboard prefabricating, external wallboard storing, external wallboard transporting, external wallboard hoisting, sealing treatment of the coupling positions between the external wallboards and waterproof coating spraying. Through the structure that the external wallboards are coupled in the horizontal direction and the vertical direction, the path of water entering a room from the outside can be prolonged to the maximum extent, and after the waterproof effect of an outer side material fails, the structure of the external wallboards has a blocking effect on the water; and multiple waterproof barriers are adopted, the waterproof coating on the outermost layer has the characteristics of being high in strength, elongation and rebound resilience, excellent in fatigue resistance and aging resistance and the like, and the first waterproof requirement of the outer surface of a fabricated building is met.

Description

Technical field [0001] The present invention relates to the field of assembly building, in particular a waterproof system for assembled outer wall panels and its construction methods. Background technique [0002] In recent years, in order to promote the development of building industrialization, the state has vigorously promoted assembly architecture, and provinces and cities responded, requiring new architectural assembly rates to meet certain requirements. Although the assembled building is an effective way to transform the traditional construction methods such as saving, intensive, environmental protection, green, and technology. Among them, non-load-bearing prefabricated components are generally used in engineering, and the prefabricated plunge wall panels have a lot of demand in our country. Prefabricated concrete flip wall panels as an integral part of the building envelope system, closer to the curtain wall structure, bypasses and decorative effects. Since the quality and...

Problems solved by technology

[0006] The above applications all involve optimizing the waterproof performance of the prefabricated wall, but there is some inconvenience during operation, and there are any joints in the structure. When the sealing material fails, water will enter the room, which cannot achieve effective waterproof and drainage effects. Therefore, there is still room for further improvement in practical applications.
