Problems solved by technology
Manually positioning and fixing the box in the reserved hole is difficult to operate and control, with large errors, and horizontal and vertical displacements are prone to occur in the process of repairing the hole, making it difficult to control the installation quality of the box; it is difficult to groove the wall and repair the hole. When the reserved hole is too large, hollowing and cracks are likely to occur when the hole is repaired. If there are too many grooves on the wall, the strength of the mortar after filling the groove cannot be guaranteed to fully meet the requirements, which will have a certain impact on the stability of the wall structure and Quality hidden danger
Therefore, this method has many procedures, difficult construction, low construction efficiency, labor and time-consuming, and high overall cost. In addition, a large amount of dust and construction waste generated by wall slotting and hole repair pollute the environment.

Embodiment Construction
[0049] Such as Figure 1 to Figure 7 As shown, the one-time installation method of the built-in wall concealed assembly electric box of the present invention includes the following steps:
[0050] Step 1. Determine the position of the wall to be built: According to the construction design drawings, draw two black lines 20 for the wall to be built on the ground 16 directly opposite to the structural beam 17, and draw the building on the surrounding concrete wall 1m black line;
[0051] When actually drawing two positioning black lines 20, draw two positioning black lines 20 based on the projection of the structural beam 17 on the ground 16 to ensure that the masonry wall is connected with the structural beam 17 when the masonry wall is built. Two locating black lines 20 provide a reference basis for the horizontal position of the box 19, and a 1m black line of a building provides a reference basis for the height position of the box 19.
[0052] Step 2: Fix the box positioning tool, ...

The invention discloses a method for one-stop concealed installation of a distribution box in wall building after construction. The method includes the following steps: 1. determining the position of a to-be-built wall body; 2. fixing a positioning tool of a box body; 3. installing the box body of the distribution box and fixing an installation position of the box body; 4. connecting an electrician wire pipe; 5. building the wall body; 6. mending a hole and cleaning construction waste; and 7. dissembling the positioning tool of the box body. According to the invention, the method herein has simple steps and high efficiency, can one-stop install the box body by positioning the installation height and the installation depth, is easy for follow up wall building, prevents the environment from being polluted by construction waste and powder which are caused by grooving the wall body, reduces construction difficulty of manual work, reduces labor and material consumption, and increases the stability of wall structure and construction quality of the wall body.
Description
Technical field [0001] The invention belongs to the technical field of building electrical installation, and specifically relates to a one-time installation method of a built-in wall concealed assembly electric box after a building. Background technique [0002] For the installation of concealed assembly of electrical boxes on the wall after construction, the traditional construction method is to first build the wall and reserve holes, secondly to locate and fix the manual box; then slot in the wall for electrical piping construction; Repair reserved holes and wire slots and clean up construction waste. The manual positioning and fixing of the cabinet in the reserved hole is difficult to operate and control, the error is large, and the horizontal and vertical displacement is easy to occur in the process of repairing the hole, the quality of the cabinet installation is difficult to control; the wall groove and the hole repair are more difficult. When the reserved hole is too larg...
