Description

Technical Field

[0001] The utility model relates to the technical field of junction box installation, in particular to an internal support and reinforcement installation structure of an electromechanical junction box in an immersed tube tunnel. Background Art

[0002] Junction boxes are widely used in electrical engineering, serving as crucial devices for connecting multiple circuits or dividing a single circuit into multiple branches. They also serve as nodes for circuit maintenance. Junction boxes used in building electrical systems typically measure 86*86*50mm. Conventional installation involves tying the box to wall reinforcement, filling the interior with foam, and then pouring concrete. However, during building construction, it has been found that pouring concrete for large structures, such as structural columns, can easily cause the junction box to shift, deform, and break. This is particularly true for immersed tube tunnel electromechanical projects, where the junction boxes measure 300*300*300mm. Furthermore, the wall thickness of immersed tube tunnel construction is 1.5m greater than that of building construction, far exceeding the typical wall thickness of building construction. Using existing installation structures for immersed tube tunnel junction boxes can also lead to misalignment, deformation, and damage, hindering subsequent installation and, consequently, compromising construction quality.

[0003] In response to the above technical problems, a support and reinforcement installation structure for the electromechanical junction box of an immersed tube tunnel is proposed. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an internal support and reinforcement installation structure for the electromechanical junction box in an immersed tube tunnel.

[0006] A structure for reinforcing and installing an internal support for an electromechanical junction box in an immersed tube tunnel comprises a frame structure and an internal support reinforcement structure. The frame structure comprises an embracing frame and a fastening frame. The embracing frame is welded into a square frame shape by a plurality of steel bars. The fastening frame is welded on three sides and installed on the outer periphery of the embracing frame. One side of the embracing frame is open for placing a junction box. Fixed ends are formed at the upper and lower ends of the fastening frame, and the fixed ends are connected to the main reinforcement of the immersed tube structure. The internal support reinforcement structure is made of a plurality of wooden templates staggered horizontally and vertically, and is clamped inside the junction box.

[0007] Furthermore, the internal support reinforcement structure formed by a plurality of wooden templates staggered horizontally and vertically is a well-shaped internal support reinforcement structure.

[0008] Furthermore, the size of the junction box is 300*300*300mm.

[0009] Furthermore, the size of the frame structure is 310*310*310mm.

[0010] Furthermore, the surrounding frame is welded from HRBφ12mm hot-rolled round steel bars or steel bar ends.

[0011] Furthermore, the fastening frame is welded from HRBφ12mm hot-rolled round steel bars or steel bar ends.

[0012] Furthermore, the wooden template is 3 mm thick.
