Method for constructing external walls

Abstract

The invention discloses a method for constructing external walls. The method includes steps of 1), arranging pouring formworks on two sides of each shear wall to be poured, and integrally connecting the pouring formworks on the two sides of each shear wall with each other by opposite pull lead screws; 2), pouring concrete between the formworks on the two sides of each shear wall, allowing the poured concrete to be formed to obtain the shear walls, detaching the opposite pull lead screws and the formworks on the two sides of each shear wall and allowing indoor and outdoor through holes to be formed in certain positions of the shear walls; 3), plugging opening ends of the outsides of the holes by rubber plugs; 4), injecting cement mortar or foaming agents in the holes from opening ends of the insides of the holes and enabling the holes to be compactly filled with the cement mortar or the foaming agents; 5), laying bricks to form brick walls between the adjacent shear walls and forming the integral external walls by the brick walls and the shear walls in an enclosed manner; 6), plastering internal wall surfaces of the external walls; 7), plastering external wall surfaces of the external walls. The opposite pull lead screws are detached from the certain positions of the shear walls. The method has the advantages that a process for plugging the holes is easy to operate and can be monitored, waterproof effects can be effectively guaranteed, the later maintenance cost can be saved, and the method has an excellent popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of exterior wall construction, in particular to an exterior wall construction method. Background technique [0002] Usually, the exterior wall of a building is surrounded by a shear wall and a brick wall. During the construction of the shear wall, firstly, the pouring formwork is set on both sides of the shear wall to be poured, and the formwork on both sides is connected into a whole with ordinary paired wire rods, so that Reinforce the formwork, and then start pouring concrete. After the concrete building is formed, the drawing rods are removed to leave a hole through the outside. For such holes, if the seal is not dense, a large outer wall will be left after the house is used. Water seepage hazard. Usually, there are two ways to seal this type of hole, one is to inject grout from the inside before the interior plastering, and the other is to inject grout from the outside when the exterior is plastered....
