Embodiment 1

[0017] A construction method for pre-embedding and assembling a concrete prefabricated frame of an electric box in a masonry structure, the specific steps and parameters are as follows:

[0018] 1. Fabrication of concrete prefabricated frame for distribution box: Prefabricated concrete frame in advance according to the size of the concealed electric box. The height of the prefabricated frame is 50mm (the deviation is not greater than ±10mm), and the thickness is the same as the thickness of the distribution box. Each side of the prefabricated frame is around It is 25mm larger than the distribution box (the deviation is not more than ±5mm), and the prefabricated frame is made of C20 concrete;

[0019] 2. Line positioning: put the wall positioning line, and mark the size, position and elevation of the opening of the distribution box;

[0020] 3. Masonry prefabricated frame installation: masonry the wall, and build the prefabricated concrete frame in the wall at the opening of th...

Abstract

The invention discloses a construction method of a concealed distribution box in a pre-buried concrete prefabricated frame in a brickwork structure, and belongs to the technical field of brickwork structures. The method includes the steps of preparing the concrete prefabricated frame of the distribution box, conducting paying-off and positioning, installing the laid prefabricated frame, and fixedly installing the distribution box. The method has the advantages that the process is simple and convenient to implement, the method is widely used for installing the concealed distribution box in thebrickwork structure, the size deviation of a reserved hole of a traditional distribution box is reduced, and the construction progress of the brickwork structure is accelerated.

Description

technical field [0001] The invention belongs to the technical field of masonry structure engineering, and in particular relates to a construction method of a pre-embedded concrete prefabricated frame in a masonry structure concealing an electric box. Especially for the projects with a large amount of work and urgent construction period requirements for the dark-assembled electric box. Background technique [0002] At present, in the process of installing a concealed electrical box in the secondary structure, it is usually practiced to reserve a hole in the secondary structure according to the size of the concealed electrical box, and to install a load-bearing lintel on the masonry structure. This construction method often causes deviations in the size of the reserved openings, and affects the construction of the subsequent masonry structure during the construction of the lintel, resulting in construction intervals. SUMMARY OF THE INVENTION [0003] The purpose of the pres...
