A prefabricated alcove-type construction technology with reserved holes for household electric boxes

Abstract

The invention relates to a niche-preformed type construction process of reserved holes of residence household electric boxes. The integral construction process is convenient and quick and high in reliability, quality defects like cracking and drums of finishing layers of the backs of the electric boxes can be remarkably reduced or eliminated, and the integral construction process is high in efficiency, free of much construction waste and conducive to energy conservation and environment protection. In the construction process, a U-shaped enclosure plate and a cover plate are independently manufactured respectively, difficulty in member machining and manufacturing is lowered and compactness and impression in manufacturing and molding are improved. The construction process can directly reduce repair of drums and cracking of at least one wall of each household and reduce maintenance cost caused by the like problems, excellence of construction and satisfaction rate of users can be improved, potential economic benefits are considerable, and massive popularization and application are facilitated.

Description

technical field [0001] The invention relates to a construction technique, in particular to a prefabricated alcove-type construction technique for a reserved hole in a household electrical box, and belongs to the technical field of building construction. Background technique [0002] For residential projects, satisfying the building's use function is the most basic requirement, and some common quality defects will appear more or less during the construction process and after delivery of the residence, although the common quality defects will not cause substantial harm, but It has indeed brought inconvenience to the residents. Among them, the hollowing and cracking of the wall at the household electric box has been a problem that has plagued the majority of builders. Through practical experience, several methods have also been summed up, such as behind the wall where the pipelines of the household electric box are concentrated Laying steel wire mesh in the plaster layer, or p...

[0002] For residential projects, satisfying the building's use function is the most basic requirement, and some common quality defects will appear more or less during the construction process and after delivery of the residence, although the common quality defects will not cause substantial harm, but It has really brought inconvenience to the residents

Among them, the hollowing and cracking of the wall at the household electric box has been a problem that has plagued the majority of builders. Through practical experience, several methods have also been summed up, such as behind the wall where the pipelines of the household electric box are concentrated Laying steel wire mesh in the plastering layer, or pouring concrete in the reserved position later, but it has been proved by practice that either the effect is not obvious or the cost is high, the process is many, and the construction period is long, which cannot meet the needs of on-site production.

Therefore, how to completely solve the common quality problem of hollowing and cracking at the position behind the reserved hole wall of the residential household electric box has become a technical problem that technicians in the field have been overcoming. Most of the traditional techniques have the following disadvantages: 1) The household electric box occupies The wall space is large, and the wall is severely damaged during the wall chiseling process, and the wall on the back of the box cannot be preserved; 2) The thickness of the household electric box is close to the thickness of the wall. Common quality problems such as hollowing and cracking will still occur after dusting, which will affect the use function of the owner after delivery; 3) There are many construction procedures, cross-operations have a great influence on each other, the efficiency is low, and a large amount of unnecessary construction waste is generated, which is not conducive to energy conservation and environmental protection; These phenomena that exist in the prior art urgently need a kind of new technical solution to solve the above-mentioned technical problem
