Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method for a concealed distribution box body in a masonry wall. Background Art

[0002] In modern building electrical installation projects, the distribution box is the key hub for power distribution and control, and its installation quality directly affects the safety, stability and functionality of the entire building electrical system.

[0003] The usual practice is to set lintels and reserved holes when the wall is built, then conceal the distribution box body, and then perform secondary sealing around and on the back of the box body; during the construction process, the size of the reserved holes is usually estimated based on experience, and it is difficult to accurately match the actual size of the distribution box body. If the hole is too large, it will destroy the integrity of the wall structure and weaken the bearing capacity of the wall. At the same time, when repairing the holes later, the construction workload and material consumption will increase, and the repaired parts are prone to cracks, hollows and other quality problems; if the hole is too small, it is necessary to forcibly expand the hole or cut and grind the distribution box body, which will not only damage the anti-corrosion layer and appearance of the box body and reduce the service life of the box body, but also may affect the sealing of the box body, allowing dust, moisture, etc. to invade the box, accelerating the aging and damage of electrical components; and the prefabricated installation of lintels and secondary sealing of the box body has many processes, resulting in increased construction costs.

[0004] In order to avoid the above-mentioned quality problems and achieve cost reduction and efficiency improvement, measures need to be taken to install and fix the concealed switch box in the masonry wall in advance, and then the wall masonry is completed in one go to avoid secondary blocking of the box. Furthermore, this application proposes a construction method for pre-installing and fixing the concealed switch box in the masonry wall. Summary of the invention

[0006] The technical solution of the present invention is a construction method for concealed installation of a distribution box body in a masonry wall, the construction method comprising the following steps:

[0007] Step 1: Positioning and laying out: According to the design requirements of the drawings, accurately locate the position and installation height of the distribution box, lay out the lines on the concrete base above the floor, mark the fixing position of the expansion bolts, and make the length of the suspension rod according to the installation height of the distribution box to ensure that the height adjustment range meets the installation requirements;

[0008] Step 2: Production and installation of the suspension rod: The suspension rod is made of galvanized steel square tube. The length is determined according to the installation height of the distribution box. The upper end is fixed to the floor slab with expansion bolts, and the lower end is lower than the bottom edge of the distribution box.

[0009] Step 3: Production and installation of T-shaped fixings: T-shaped fixings are made of galvanized steel square tubes and welded to the connecting parts of the suspension rod. After the T-shaped fixings are completed, they are sleeved on the suspension rods and adjusted to the appropriate height in combination with the lifting and installation equipment. Tighten the height adjustment bolts. The height adjustment bolts are installed in two pieces, upper and lower, to facilitate the fixing of the distribution box body;

[0010] Step 4: Install the distribution box: Place the distribution box on the T-shaped fixings, and adjust the height adjustment bolts to make the two T-shaped fixings close to the upper and lower inner walls of the distribution box. After verifying that the installation height of the distribution box meets the requirements, tighten the top bolts;

[0011] The lifting and installation equipment specifically includes a front card plate located below the distribution box body for bearing and a side card plate pulled out and arranged inside the front card plate.
