[0002] In recent years, with the development of urban construction, the demand for urban transportation has been increasing. With the continuous improvement of the requirements for rail transit construction, more flexibility is needed in the project. The existing technology for cable mezzanine of elevated stations is to set fixed cable brackets on the wall, which places great demands on the wall load. In addition, the cable mezzanine floor of elevated stations is usually equipped with a waterproof layer and a heat insulation layer. Using conventional cable brackets that are fixed on the ground will cause some damage to the waterproof layer. Summary of the Invention

The upper support pole has a first support seat at its upper end, which is connected to the existing upper structural plate. The lower end of the upper support pole is threaded. The lower end of the lower support pole has a second support seat at its lower end, which is connected to the existing lower structural plate. The upper end of the lower support pole is threaded. The middle connecting pole is threaded to both the upper and lower support poles. The cable hanging assembly is mounted on either the upper or lower support pole.

[0008] Preferably, the upper support rod is provided with fixing holes and fixing screws, and the fixing screws are used to fix the middle connecting rod and fixing holes.

[0009] Preferably, the cable hanging assembly includes a base and a hanging rod, the hanging rod is connected to the base, the base is connected to the upper support rod, and multiple cable hanging assemblies are arranged in the vertical direction.

[0010] Preferably, the upper support rod is longer than the lower support rod, and the cable hanging assembly is installed on the upper support rod.

[0011] Preferably, the central steel component is provided with hexagonal bolt heads.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model achieves telescopic fixing of the fixing rod assembly, improving practicality and flexibility. The design of the assembly makes the installation process simple and convenient, reduces installation difficulty, and allows for unrestricted installation positions. It avoids damage to the waterproof and insulation layers, reduces safety hazards, and ensures the integrity of the building structure. This utility model is not constrained by the load-bearing capacity of the side walls in terms of form and structure, which is more conducive to the design of the station in terms of structure and shape.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1-6 As shown, this embodiment provides a station cable interlayer combined fixing rod, including an upper support rod 1, a middle connecting rod 7, a lower support rod 2, and a cable hanging assembly 6. In this embodiment, the upper support rod 1, the middle connecting rod 7, and the lower support rod 2 are all rigid components.

[0023] The upper end of the upper support rod 1 is welded to a first support seat 3. The first support seat 3 is provided with a threaded hole. The first support seat 3 is connected to the existing cable interlayer upper structural plate by expansion bolts 5. A first elastic gasket 4 is provided between the first support seat 3 and the existing cable interlayer upper structural plate. The lower end of the upper support rod 1 is provided with threads. The upper support rod 1 is provided with fixing holes 9 and fixing screws 8.

[0024] The lower end of the lower support rod 2 is welded to a second support seat 10, which stands on the existing lower structural plate of the cable interlayer. A second elastic gasket 11 is provided between the second support seat 10 and the existing lower structural plate. The upper end of the lower support rod 2 is provided with threads.

[0025] The middle connecting rod 7 has threaded posts at both ends. The upper and lower threaded posts are respectively provided with threads corresponding to the upper support rod 1 and the lower support rod 2. The threaded posts are partially flattened at both ends. The middle connecting rod 7 has a hexagonal screw head in the middle.

[0026] The upper support rod 1, the middle connecting rod 7, and the lower support rod 2 can be installed by thread matching to achieve the effect of telescopic fixation. After installation and adjustment to the appropriate length, the middle connecting rod 7 is fixed to the upper support rod 1 through the fixing hole 9 and the fixing screw 8. The upper structural plate bears the load and the lower structural plate supports it, thus eliminating the constraint on the side wall in terms of form and structure.

[0027] The cable hanging assembly 6 is mounted on the upper support rod 1 or the lower support rod 2. The cable hanging assembly 6 includes a base and a hanging rod. The base is connected to the upper support rod 1 or the lower support rod 2. Multiple cable hanging assemblies 6 can be provided. In this embodiment, the upper support rod 1 is longer than the lower support rod 2, and the cable hanging assembly 6 is mounted on the rod with the larger length, that is, the cable hanging assembly 6 is mounted on the upper support rod 1.

[0028] Working principle: The upper support rod 1 is equipped with a cable hanging assembly 6. The first support seat 3 welded to the upper support rod 1 is pressed on the first elastic pad 4 and fixed to the existing cable interlayer upper structural plate by expansion bolts 5. The second support seat 10 welded to the lower support rod 2 presses down on the second elastic pad 11 and stands on the existing cable interlayer lower structural plate. By rotating the hexagonal screw head in the middle of the central steel component 7, the length of the cable fixing rod assembly is adjusted so that the upper support rod 1, the central connecting rod 7 and the lower support rod 2 are combined and fixed between the existing cable interlayer upper and lower structural plates. Tighten the threaded column 7 to make the assembly tight and fixed and align with the fixing hole 9. Tighten the fixing screw 8 to fix it.

[0029] This utility model achieves telescopic fixing of the fixing rod assembly, improving practicality and flexibility. The design of the assembly makes the installation process simple and convenient, reduces installation difficulty, and allows for unrestricted installation positions. It avoids damage to the waterproof and insulation layers, reduces safety hazards, and ensures the integrity of the building structure. This utility model is not constrained by the load-bearing capacity of the side walls in terms of form and structure, which is more conducive to the design of the station in terms of structure and shape.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
