Description

Technical Field

[0001] The utility model relates to the technical field of terminal boxes, in particular to a buried equipotential bonding terminal box. Background Technique

[0002] The SSGF construction method is a modern new building construction technology that uses reinforced concrete to be cast integrally at one time. There is no need to build bricks and plaster the wall, which eliminates the quality and safety problems such as leakage, cracking, hollowing, and external wall peeling caused by bricklaying and plastering from the source. It has the advantages of reducing space waste, enhancing the safety of the house, and reducing the construction period. Therefore, the SSGF construction method is used more and more.

[0003] At present, the installation of the equipotential bonding terminal box in the toilet under the SSGF construction method needs to be pre-buried and installed in the building structure steel bars, and after the formwork is removed, the equipotential bonding terminal box needs to be flush with the wall surface, with high aesthetic requirements. However, there is no equipotential bonding terminal box suitable for this process installation in the existing market. The existing equipotential bonding terminal boxes are basically designed based on excavating holes in brick walls. Using this product for pre-buried installation is very easy to cause deviation in the up and down and front and back positions, and it is difficult to be flush with the wall surface. Multiple chiseling and repair operations are required later, which is easy to cause the wall to be hollow, and the appearance of the wall does not look beautiful enough. Content of the Utility Model

[0004] The purpose of the utility model is to provide a buried equipotential bonding terminal box to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A buried equipotential bonding terminal box, including a box body, fixed blocks are symmetrically arranged at the top and bottom of the outer side of the box body, a first fixing hole for the steel bar to pass through is penetrated inside the fixed block, and a plurality of fixed cylinders are arranged at the rear side of the box body, and a second fixing hole for inserting a PVC pipe is opened inside the plurality of fixed cylinders.

[0006] As a preferred scheme of the utility model, the plurality of fixed cylinders are on the same horizontal line.

[0007] As a preferred scheme of the utility model, the horizontally adjacent first fixing holes are on the same straight line.

[0008] As a preferred scheme of the utility model, threading cylinders are arranged at the top and bottom of the outer side of the box body, a threading hole is penetrated through the threading cylinder, and the threading hole is communicated with the inside of the box body.

[0009] As a preferred scheme of the utility model, the box body, the fixed block, the threading cylinder and the fixed cylinder are of an integrally injection-molded structure.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: When the utility model is pre-embedded and installed, the steel bar is passed through the first fixing hole, and then the steel bar is tied to the building structure steel bar to fix the box body and prevent it from moving up and down. The PVC pipe is inserted into the second fixing hole, and when the front and rear templates are spliced, it can also play a role in fixing the box body and prevent the box body from moving back and forth, so as to achieve non-displacement during pre-embedded installation. Moreover, after the front and rear templates are removed, the box body will be flush with the wall surface, which not only makes it more beautiful, but also improves the construction efficiency.

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a pre-embedded equipotential bonding terminal box, including a box body 1. Fixing blocks 2 are symmetrically arranged at the top and bottom of the outer side of the box body 1. A first fixing hole 3 for the steel bar to pass through is penetrated inside the fixing block 2. A plurality of fixing cylinders 6 are arranged at the rear side of the box body 1. A second fixing hole 7 for the PVC pipe to be inserted is opened inside the plurality of fixing cylinders 6. During pre-embedded installation, the steel bar is passed through between two adjacent first fixing holes 3, and the PVC pipe is inserted into the second fixing hole 7. The length of the PVC pipe is flat against the inner side of the template. Then the steel bar is tied to the building structure steel bar to fix the box body 1 and prevent it from moving up and down. Subsequently, when the front and rear templates are spliced, the front of the box body 1 will be closely attached to the inner side of the front mold, and the PVC pipe will be closely attached to the inner side of the rear mold, so as to also fix the box body 1 and prevent the box body 1 from moving back and forth. Since the front of the box body 1 is closely attached to the inner side of the front mold, when the front and rear templates are removed, the front of the box body 1 will be flush with the wall surface, which not only makes it more beautiful, but also improves the construction efficiency.

[0017] Among them, multiple fixed cylinders 6 are on the same horizontal line, so that when the PVC pipe is inserted into the second fixing hole 7, the box body 1 can be kept in a horizontal state.

[0018] Among them, the horizontally adjacent first fixing holes 3 are on the same straight line, which is convenient for steel bars to pass through the first fixing holes 3.

[0019] Among them, threading cylinders 4 are provided at the top and bottom of the outer side of the box body 1, and threading holes 5 are provided through the threading cylinders 4. The threading holes 5 are convenient for external wires to penetrate into the box body 1 for wiring, and the threading holes 5 are communicated with the inside of the box body 1.

[0020] Among them, the box body 1, the fixing blocks 2, the threading cylinders 4 and the fixed cylinders 6 are of an integrally injection-molded structure. The integrally injection-molded structure has high production efficiency and ensures firm connection between various components.

[0021] Specifically, during embedded installation, steel bars are respectively passed through between two adjacent first fixing holes 3, and PVC pipes are inserted into the second fixing holes 7. The length of the PVC pipes is flat against the inner side of the formwork. Then, the steel bars passing through the second fixing holes 7 are tied to the building structure steel bars, so as to fix the box body 1 and prevent it from moving up and down. Subsequently, after the front and rear formworks are spliced, the front of the box body 1 will be close to the inner side of the front formwork, and the PVC pipes will be close to the inner side of the rear formwork, so as to also fix the box body 1 and prevent the box body 1 from moving back and forth. When the front and rear formworks are removed, the front of the box body 1 will be flush with the wall surface.
