Roof deformation joint waterproof structure and construction method

Abstract

The embodiments of the invention provide a roof deformation joint waterproof structure and a construction method. The roof deformation joint waterproof structure comprises two side roofs and a roof deformation joint between the two side roofs; a middle-buried rubber water stop belt is poured in the middle of the roof deformation joint and between the two side roofs; the roof deformation joint is internally filled with polyethylene foaming joint filling plates located above and below the middle-buried rubber water stop belt; an upper port of the roof deformation joint is covered with an externally-attached type water stop belt; the externally-attached type water stop belt and the top faces of the two side roofs are covered with coiled material isolation layers; rubber strips are arranged at the positions, located above the roof deformation joint, of the coiled material isolation layers; coiled material waterproof additional layers cover the coiled material isolation layers; concrete protection layers are poured on the coiled material waterproof additional layers; a groove is reserved in the position, opposite to the roof deformation joint, of each concrete protection layer; and each groove is filled with sealant. According to the scheme provided by the embodiment of the invention, the problems that simultaneous and synchronous construction of the externally-attached type water stop belt and the sealant is difficult, working procedures influence one another, and the overall quality is difficult to control are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a roof deformation joint waterproof structure and a construction method. Background technique [0002] In building construction, the roof nodes in "10J301 Underground Waterproof Construction" are usually selected according to the requirements of the atlas to carry out the waterproof construction of the deformation joints of the roof. [0003] However, when the externally attached waterstop is installed before pouring concrete, since the surface of the externally attached waterstop has a large contact area with the concrete, it will be connected with it when the concrete is poured and bonded firmly, which will cause deformation on the roof It is difficult to fill the sealing paste on the polystyrene slats in the joints, and the quality of the filling cannot be guaranteed; and if the external waterstop is installed after the concrete is poured, the concrete has solidi...

Problems solved by technology

[0003] However, when the externally attached waterstop is installed before pouring concrete, since the surface of the externally attached waterstop has a large contact area with the concrete, it will be connected with it when the concrete is poured and bonded firmly, which will cause deformation on the roof It is difficult to fill the sealing paste on the polystyrene slats in the joints, and the quality of the filling cannot be guaranteed; and if the external waterstop is installed after the concrete is poured, the concrete has solidified and hardened after the sealing paste is embedded, and the external waterstop cannot be installed. The face edges on the surface of the hose are pressed into the concrete to form a whole;

[0004] In addition, if the waterproof layer is directly laid on the top of the roof, it is easy to cause the waterproof layer of the membrane to tear due to the out-of-sync deformation of the roof concrete and the waterproof membrane; the sealant on the lower side of the deformation joint is easy to fall due to gravity, which affects the appearance and use requirements
