Construction method for preventing efflorescence at corners of building wall

Abstract

The invention discloses a construction method for preventing efflorescence at corners of a building wall. The construction method comprises the following steps that preparation before construction isconducted; the building wall is constructed, specifically, a foundation and a wall frame of the building wall are constructed; a dry hanging structure is designed, specifically, a red brick layer, a hanging piece, a force-bearing piece and a sound absorption layer are sequentially arranged on the wall frame from outside to inside; the red brick layer is pasted, specifically, before red bricks aremounted, anti-alkali treatment agents are smeared on the back faces and side faces of the red bricks, meanwhile, resin glue is smeared at the bottoms of the red bricks, and then chemical fiber mesh cloths are pasted to form an anti-pull waterproof layer; whitewashing is conducted, specifically, putty whitewashing is conducted on the outer side of the mounted red brick layer; and prevention treatment is conducted, specifically, the whitewashed wall is washed through 10% of an oxalic acid solution and washed through fresh water after being washed completely, and after being fully dried, the wallis sprayed through a solidification waterproof agent. The construction method starts from the three aspects of design preparation before construction, reducing of generation of substances such as Ca(OH) 2 and salt, and prevention treatment after construction, and generation of the efflorescence phenomenon at the corners of the building wall is lowered.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for preventing efflorescence at the corner of a building wall. Background technique [0002] The walls mainly include load-bearing walls and non-load-bearing walls, which mainly play the role of enclosure and space separation. The wall of the load-bearing structure of the building combines load-bearing and enclosure, and the function of the wall of the skeleton structure system is to enclose and separate the space. The wall should have sufficient strength and stability, and have the ability of heat preservation, heat insulation, sound insulation, fire prevention and waterproof. There are many types of walls, including walls made of a single material and walls made of composite materials. It is an important task of building construction to design a reasonable wall scheme by comprehensively considering factors such as enclosure, load bearing, energy saving, ...

Problems solved by technology

[0004] Alkali, salt and other components produced by bonding materials are the direct source of efflorescence that penetrates into the pores of stone materials. Therefore, in actual construction, we need to prevent the occurrence of efflorescence, otherwise it will not only affect the quality of the entire building. reduce, but also make the wall unsightly, which seriously affects the later use effect of the building wall, and the practicability is not strong
