Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a pre-buried electrical pipeline structure applied to a large template cast-in-place wall. Background Art
[0002] In construction projects, it is often encountered that the wire pipes concealed in the reinforced concrete wall need to pass vertically through the wall, such as Figure 1 As shown, the conventional practice is to drill holes in the template and lead the pipeline out of the template.
[0003] like Figure 2 As shown, when a large formwork is used to cast a reinforced concrete wall, in order to maintain the integrity of the formwork, holes are not allowed to be opened on the formwork. The electrical conduit in the wall cannot extend beyond the formwork, and a wire box needs to be set at the location where the conduit passes through the wall to facilitate connection with the conduit outside the wall.
[0004] However, the disadvantages of this approach are obvious. In order to allow the wire tube to pass smoothly, a cover plate needs to be set on the box mouth, and a hole is opened in the middle of the cover plate to install the wire tube. When the cover plate and the wire tube are installed on the box mouth, the three will form a closed space. When threading the wires, the box cover together with the exposed wire tube must be removed, and then restored after the wires are threaded. Another disadvantage is that the jumper ground wire is half inside the wall and half outside the wall, and the jumper ground wire inside the wall cannot be protected as a finished product. In short, this construction method has too complicated procedures, great construction difficulty, and many defects.
[0005] Therefore, there is an urgent need for a pre-buried electrical pipeline structure for large-formwork cast-in-place walls to solve the above-mentioned technical problems. Utility Model Content
[0006] The utility model aims to solve the above-mentioned problem, thereby providing a pre-buried electrical pipeline structure applied to large-formwork cast-in-place walls, which ensures that the electrical wire pipes are unobstructed at the wall penetration point, and there is no need to remove the exposed electrical wire pipes outside the wall when threading the wires, thereby simplifying the process of traditional construction methods, improving construction efficiency, hiding the grounding wire in the electrical junction box, and effectively protecting the grounding wire located inside the wall.
[0007] The utility model solves the above problems and adopts the following technical solutions:
[0008] A pre-buried electrical pipeline structure applied to a large-formwork cast-in-place wall is arranged on the cast-in-place wall.

Any side of the electrical junction box is flush with the outer side of the cast-in-place wall. An opening is arranged on the side of the electrical junction box that is flush with the outer side of the cast-in-place wall. A through hole is arranged on the side of the electrical junction box opposite to the opening. A concealed wire pipe pre-buried in the cast-in-place wall is inserted in the through hole. A cover plate is detachably installed on the opening of the electrical junction box. A mounting hole is arranged on the cover plate. An exposed wire pipe detachably connected to the concealed wire pipe is inserted in the mounting hole. A grounding wire is arranged in the electrical junction box. One end of the grounding wire passes through the electrical junction box and is fixed to the concealed wire pipe, and the other end of the grounding wire passes through the cover plate and is fixed to the exposed wire pipe.

[0011] Preferably, a sealing sheet is provided on the outer side surface of the electrical junction box, and the sealing sheet is sleeved on the concealed wire tube.

[0015] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:
[0016] The surface-mounted wire pipe of the utility model is connected into a whole by a pipe clamp joint and a concealed wire pipe, which ensures that the wire pipe at the wall penetration is unobstructed.
