Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a precast concrete integrated distribution box and a mould. Background Art

[0002] The construction of a distribution box typically involves pre-setting a hole in the wall for the box and pre-setting wire ducts for the box. The box is then placed after the wall is built, and the wall surrounding the box is trimmed and patched. Traditional construction techniques often result in inaccurate placement of the reserved hole, resulting in a large amount of construction debris after the trimming process. During the trimming and patching of the wall hole and duct, the distribution box is easily squeezed, causing displacement and deformation, and hollowing at the joints. This consumes significant manpower and material resources, and can negatively impact the integrity and stability of the wall structure.

[0003] To this end, we propose a precast concrete integrated distribution box and mold. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a precast concrete integrated distribution box and a mold.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is:

[0006] A precast concrete integrated distribution box comprises: a shell, which is a rectangular box with an opening at the front, a mounting assembly provided inside the shell, the mounting assembly being used to install a power supply unit and a signal transmission unit, and a wiring hole being provided on at least one side wall of the shell; a covering member, which covers the outside of the shell, and a wiring groove is provided on the covering member at a position corresponding to the wiring hole, and the covering member is connected to the concrete of the wall.

[0007] By providing a covering part, the covering part is pre-molded with the shell, and then the molded shell and the covering part are embedded in the reserved cavity in the wall, and then the gap between the covering part and the wall is filled and leveled by masonry mortar. The covering part can form a support for the external wall. Compared with directly embedding the shell into the wall, the covering part is less squeezed by the wall and is less likely to deform. In addition, during the installation process, compared with the method of installing the box with reserved holes, there is no need to chisel and hammer, and there will be no large amount of construction slag. The joints are neat, which saves manpower and improves the stability of the shell.

[0008] It is further defined that the covering parts are made of cast concrete; prefabricating the covering parts by cast concrete can make the connection between the covering parts and the wall tighter and more stable.

[0009] It is further defined that the installation component includes a power supply mounting frame and a signal box. The power supply mounting frame is convex in shape and is fixedly connected to the back of the shell by screws at both ends. A number of mounting holes are evenly spaced along the length direction of the power supply mounting frame on the raised portion of the power supply mounting frame. There are two power supply mounting frames arranged in the up and down directions; the signal box is a rectangular box body with openings on the top and back. A fixing block is provided on the left and right sides of the signal box, and the signal box is fixed to the back of the shell by screws passing through the fixing blocks.

[0010] By setting up a convex-shaped power supply mounting bracket, power supply components such as plug boards are fixed to the mounting holes of the raised part of the power supply mounting bracket by bolts. In this way, when the power supply component is damaged and needs to be repaired or replaced, the power supply component can be directly removed from the power supply mounting bracket. Compared with directly fixing the power supply component to the reserved hole of the shell, the reserved hole of the shell is very fragile and is very easy to be damaged by multiple disassembly and assembly, resulting in loose fixation and the need for re-drilling. When passing through the power supply mounting bracket, there is no need to remove the power supply mounting bracket, and the reserved hole of the shell will not be damaged. The maintenance and replacement of the power supply component is convenient, and the stability of the power supply component in the shell is improved. The problem of loose fixation due to multiple disassembly will not occur. In addition, a number of mounting holes are provided so that the power supply component can be moved left and right on the power supply mounting bracket for adjustment. A signal box is set up for installing signal transmission components such as routers, and the signal transmission component is inserted into the signal box from the top to complete the fixation, which is very convenient.

[0011] It is further defined that a plurality of heat dissipation holes are provided on the front side of the signal box; the heat dissipation holes provided on the front side of the signal box can improve the heat dissipation performance of the signal box and can also reduce the obstruction to the signal.

[0012] It is further defined that reinforcing ribs are arranged on the side walls of the shell, and the reinforcing ribs are staggered with the wiring holes; by arranging reinforcing ribs on the side walls of the shell, the bearing strength of the shell can be further improved, and the shell can be prevented from being squeezed and deformed by the covering parts and the wall, and the deformation resistance is stronger.

[0013] A mould is used for prefabricating the above-mentioned precast concrete integrated distribution box.

[0014] The beneficial effect of the present invention is that a concrete covering is provided on the outside of the shell to protect the shell and reduce the squeezing force of the shell on the wall. Compared with the existing embedded shell, the stability of the shell is better. BRIEF DESCRIPTION OF THE DRAWINGS

Reinforcing ribs 12 are provided on the side walls of the housing 1, and the reinforcing ribs 12 are staggered with the wiring holes 11. The covering 2 is covered on the outside of the housing 1. A wiring groove 21 is provided on the covering 2 at the position corresponding to the wiring hole 11. The covering 2 is made of cast concrete. The covering 2 is connected to the concrete of the wall.

[0023] By setting a covering part 2, the covering part 2 is pre-molded with the shell 1, and then the molded shell 1 and the covering part 2 are embedded in the cavity reserved in the wall, and then the gap between the covering part 2 and the wall is filled and leveled by masonry mortar. The covering part 2 can form a support for the external wall. Compared with directly embedding the shell 1 into the wall, it is less squeezed by the wall and is less likely to deform.
