Waterproof treatment structure and treatment method of building wall interface joints

Abstract

The invention discloses a waterproof processing method on the joint of wall interfaces of a building. The method includes the steps that polymer mortar is used on the joint of the wall interfaces of the building for joint filling; leveling is performed on a basic layer; the wall is coated with polymer mortar after being leveled, the polymer mortar basal layer is sequentially coated with interface agent and primer, line snapping is performed on the two sides of the joint, and basalt fiber cloth is pasted to the position within the line snapping range; the surface of the basalt fiber cloth is then coated with interface agent, rendered with polymer mortar and coated with finish coating, and waterproof processing is completed. The invention further discloses a waterproof processing structure obtained through the waterproof processing method. The structure comprises the polymer mortar basal layer filled into the joint of the wall interfaces of the building, the polymer mortar basal layer stretches into the joint and covers the joint, and the interface agent layer, the primer layer, the basalt fiber cloth layer, the polymer mortar surface layer and the decorative layer sequentially cover the polymer mortar basal layer. According to the method and structure, the construction steps are simple, the cost is low, the efficiency is high, and the waterproof and anti-crack processing effect is good.

Description

technical field [0001] The invention relates to a treatment structure and a construction method for the interface joint of a building wall, in particular to a waterproof structure and a waterproof treatment method for the interface joint of a building wall. Background technique [0002] Cracks or joints in building walls are relatively common engineering technical problems in the field of construction engineering, but need to be avoided as much as possible. There are three types of normal cracks: mixed structure cracks, homogeneous structure cracks and decorative putty cracks. The direct causes mainly include: cracks caused by differential settlement of buildings, temperature stress cracks, dry shrinkage cracks, cracks caused by unqualified wall products, cracks caused by unqualified putty products and irregular construction. [0003] Cracks caused by differential settlement of buildings: The uneven settlement of buildings will cause additional stress in the structure, and ...

AI Technical Summary

Problems solved by technology

For the cracks in the walls of buildings that have been constructed, it is generally preferred to press the alkali-resistant glass fiber mesh cloth into the cement-lime mortar layer within a certain range of the joint interface. Tensile performance, offset the temperature stress and drying shrinkage stress at the interface of the joint, thereby avoiding cracking and water seepage at the joint of the outer wall, but the actual effect of this method is not good, and the problem of cracking of the outer wall of the building cannot be solved well
