Fabricated building prefabricated outer wall joint waterproof method

Abstract

The invention relates to building construction, in particular to a fabricated building prefabricated outer wall and provides a fabricated building prefabricated outer wall joint waterproof method. Outer wall joints include horizontal joints and vertical joints; horizontal joint waterproofing can be conducted by two methods, namely the grouting method and the bed-mortar method, and is mainly achieved by a tongue-and-groove, a cavity structure and outer wall sealing adhesive; the inner part of the tongue-and-groove is high, the outer part of the tongue-and-groove is low, and it is ensured that even if water enters in a room, one direction of water flow is still the outside of the room. Cavities of 20 mm are reserved in the inside and the outside; a material waterproof system refers to sealing adhesive at outer openings and square PE bars, and a horizontal wall body part is a hollow water-stop belt; the horizontal joints of a PCF section are blocked off by means of self-adhesion rubber, and the inner sides are casted in place; the waterproofing methods of vertical joints are same as that of the horizontal joints of the PCF section; a drainage measure includes the step of placing waterproof guide pipes in the connection positions between the outer wall horizontal joints and the outer wall vertical joints. Through structure construction waterproofing, cavity waterproofing and material waterproofing and by means of an overall-wall drainage measure system, it is ensured that an outer wall waterproofing measure has no problems.

Description

technical field [0001] The invention relates to building construction, in particular to a prefabricated outer wall of an assembled building. Background technique [0002] Due to its cost, construction speed, civilized construction and environmental advantages, the prefabricated structure has been affirmed and recognized by everyone. At present, the pace of my country's prefabricated industry is constantly increasing. [0003] Compared with the traditional cast-in-place structure, the external wall of the prefabricated structure has horizontal and vertical gaps between the prefabricated panels and the prefabricated panels, especially the horizontal joints. If waterproof measures are not taken, the leakage will be prefabricated. A big hidden danger in the structure. Contents of the invention [0004] The invention aims to overcome the defects of the prior art, and provides a method for waterproofing joints of prefabricated exterior walls of prefabricated buildings. The pre...
