Anti-cracking and anti-falling technology for box body back plaster layer pre-embedded into wall body

Abstract

The invention relates to an anti-cracking and anti-falling technology for a box body back plaster layer pre-embedded into a wall body. One surface of a metal rack body is fixed with the main body of a box body; the other surface of the metal rack body is fixed with a steel wire gauze or a steel plate gauze; steel plates in the metal rack body are arranged on the corresponding position on the edge of the main body of the box body; and all steel plates are connected by flat steel plate strips along the horizontal or vertical direction and are connected by inclined steel plate strips or steel wires along the slant direction. A construction method for plastering on the box body back comprises the following steps: arranging steel plates and steel plate strips for fixing on the box body back to form the metal rack body; before the steel plate gauze or the steel wire gauze is connected with the metal rack body, the metal rack body or the steel plates are welded on the main body of the box body; and then, the metal rack body, the steel plate gauze or the steel wire gauze can be welded or bound to form a whole. In the plastering process, mortar crashing and flowing, intermittent cracking, wall surface shrinkage cracking after plastering and plastering layer falling can be avoided, the plastering layer and the box body form a whole, and finally, the building can be normally used and has an attractive effect.

Description

technical field [0001] The invention relates to anti-cracking, anti-cracking, and anti-sanding technology for the plastering layer on the back of the box installed in the wall of a building or structure, in particular to solving the problem of plastering the back of the box buried in the wall, such as a fire box, a distribution box, etc. The technology for the cracking and falling off of the gray layer particularly relates to a box body which is pre-buried or embedded in the wall and a construction method for plastering the back of the box body. Background technique [0002] Residential buildings, public buildings, industrial buildings and agricultural buildings in our country, according to the use function, when designing the engineering function, the buildings or structures are equipped with fire-fighting facilities and power supply systems according to the design requirements. So far, the backs of large boxes buried in the walls of buildings in my country are all smooth p...

AI Technical Summary

Problems solved by technology

Due to the large and relatively thick plastering area on the back of the box, the fiber cloth or metal mesh cannot form a whole with the box, and the plastering operation is also difficult. During the construction process, the quality of the plastering is difficult to control, and often occurs Even if the plastering work is completed, after the completion of the project, the plastering layer on the back of the cabinet will be cracked to varying degrees due to material shrinkage and slight external force. In severe cases, the plastering layer will fall off. , has seriously affected the normal use and aesthetic requirements of the building, and this problem has not been well resolved for a long time
