One-time forming construction process of embedded distribution box

Abstract

The invention provides a one-time forming construction process of an embedded distribution box. The one-time forming construction process comprises the concrete steps of (1) sealing line pipe holes inthe upper side and the lower side of the embedded distribution box with plastic caps; (2) constructing a support frame by means of wooden block assembly inside the embedded distribution box; (3) filling the remaining space inside the embedded distribution box except the support frame with filler; (4) cutting a polystyrene board according to the inner diameter of a box body of the embedded distribution box, and embedding the polystyrene board into the box body; (5) welding locating bars on the back of the box body of the embedded distribution box; (6) marking the elevation of the box body andthe axis position of the embedded distribution box on shear wall reinforcement at the embedded position, and welding additional bars around the box body of the embedded distribution box; and (7) carrying out mold sealing, concrete pouring, mold removal, polystyrene board removal, filler cleaning, wooden block support removal, installation of a cover plate and finished product protection operationin sequence. The one-time forming construction process has the advantages of reducing the manufacturing and installation and removal of a one-time box formwork and achieving the purposes of shorteningthe construction time, improving the construction efficiency and reducing the construction cost.

Description

technical field [0001] The invention relates to the technical field of prefabricated component construction, in particular to a one-time molding construction process of a pre-embedded distribution box. Background technique [0002] The traditional process of installing distribution boxes is usually to make formwork wooden boxes by the carpenter team according to the actual number of boxes on site before structural construction. During structural construction, the prefabricated formwork boxes are installed in the shear wall, and the pre-embedded wooden boxes are removed after the concrete pouring is completed and the formwork is removed. , because the wooden box is made according to the size of the electrical box, the volume is small, and the formwork cannot be reused after removal, resulting in a large amount of material waste; after the wooden box is removed, install the electrical box, grouting, caulking and other processes in the reserved hole. There are many disadvantage...

[0002] The traditional process of installing distribution boxes is usually to make formwork wooden boxes by the carpenter team according to the actual number of boxes on site before structural construction. During structural construction, the prefabricated formwork boxes are installed in the shear wall, and the pre-embedded wooden boxes are removed after the concrete pouring is completed and the formwork is removed. , because the wooden box is made according to the size of the electric box, the volume is small, the formwork cannot be reused after removal, and the material waste is large; after the wooden box is removed, install the electric box, grouting, caulking and other processes in the reserved hole

There are many disadvantages in the electrical boxes installed by traditional techniques, such as: the production, installation and removal of template wooden boxes, and the wooden boxes cannot be reused, which wastes materials and labor, and the surrounding concrete structures are easy to be damaged during the removal of the wooden boxes. Installing the cabinet inside will easily lead to hollowing at the rear of the cabinet, the size of the gaps reserved around the cabinet is different, and the cracking of the wall is likely to occur if the caulking is not dense, and the cost of grouting and caulking materials for the cabinet is higher than that of concrete high
