Construction electric switch box construction method once and for all

Abstract

The invention discloses a one-time completed construction method for a building electrical distribution box. The method is to embed the box in place at a time before the concrete is cast during the construction process. The box on a wall takes the level control line on the layer as a reference, and the accurate position of the box is measured by a water level gauge, a steel measuring tape and a track level bar; lines are drawn on the surface of the box to determine the position for entering a pipeline and open an opening on the position by an opener; the box on a reinforced concrete wall is fixed on a steel mesh by a steel bar in a shape of a Chinese character 'jing'; the box on a brick wall or a light partition is connected and fixed with a matched pipeline before construction; the pipeline entering the box corresponds a hole, and the arrangement is orderly; and cut polystyrene foam plates are filled in the box and the periphery of the box is sealed by adhesive tapes. The aim of the method is to ensure the accuracy of the position of the box.

Description

technical field [0001] The invention relates to a construction method of an electrical concealed distribution box / box in the field of civil engineering, in particular to a one-time construction method for a building electrical concealed distribution box / box. Background technique [0002] In building electrical installation engineering, the traditional method of installing electrical boxes / boxes is to use the method of reserving holes. When the steel bars are bound, before the concrete is poured, according to the position and volume of the box on the concrete wall, the wood is processed into a six-sided closed wooden box in advance, and fixed on the steel mesh. After the construction of the main body of the civil work is completed, the installation and piping of the box body will be performed for the second time according to the reserved position. This method is difficult to control the position of the cavity, resulting in inaccurate control of the reserved position, which i...

Problems solved by technology

This method is difficult to control the position of the cavity, resulting in inaccurate control of the reserved position, which increases the difficulty of installing the piping in the secondary box. After the hole is repaired, it is easy to produce quality defects such as hollows and cracks, resulting in waste of artificial materials and affecting the project. progress and quality
