Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and more specifically, to a spanning cable bridge structure and a manufacturing method thereof. Background Art

[0002] Cable trays often need to be diverted for wiring needs, that is, each group of parallel main trays and adjacent branch trays need to avoid each other. At this time, three-way or four-way accessories are usually used to arrange the tray, but there are many types of cable trays, such as high-voltage trays, fire-fighting power trays, integrated wiring, security trays, etc. All types of trays need to be connected to substations or high / low-voltage rooms, and high-voltage rooms and low-voltage rooms are often arranged adjacent to each other, resulting in the location of the tray accessories of each system being relatively concentrated. In order to solve the mutual collision between the tray systems, they are often avoided by bending each other. When there are many types of systems, bending each other requires a lot of space, which greatly increases the difficulty of installation and cable laying and has low aesthetics.

[0003] Utility model patents with announcement numbers CN 205846627 U, CN 220234105 U, and CN 221202024 U all propose a lower space connection structure and connectors between the main bridge and the branch bridge. However, the implementation structure in the existing technical solution is relatively complex and time-consuming and labor-intensive during construction. Therefore, developing a spanning cable tray structure with a simplified structure and a high prefabrication ratio based on the overall design and a manufacturing method thereof is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, the present invention provides a spanning cable tray structure and a method for manufacturing the same, aiming to reduce the space required for bending cable tray accessories with each other, reduce the difficulty of installation and cable laying at the tray accessories, reduce construction costs while ensuring the overall aesthetics of the electromechanical pipeline installation.

[0005] To achieve the above-mentioned purpose, on the one hand, the present invention provides a spanning cable bridge structure, comprising a main bridge and a branch bridge, wherein a plurality of the main bridges are arranged in parallel in multiple rows; characterized in that the direction of the branch bridge is perpendicular to the main bridge, and is located in a suspended area above the main bridge; the connection portion between the branch bridge and its corresponding main bridge is not provided with a bridge fence, and is only connected to at least one side of the main bridge through a climbing section.

[0006] The supporting bridge of the present invention is located in the suspended area above the main bridge, so that accessories of different types of bridges can avoid each other clearly. In addition, the connecting part of the supporting bridge and its corresponding main bridge is not provided with a bridge fence, but is connected to the main bridge only through a climbing section, which has a simple and beautiful structure, reduces the difficulty and cost of cable laying, and reduces cable damage.

[0007] Furthermore, the angle between the climbing section and the main bridge is 45°. This structural feature can well match the bending requirements of most cables.

[0008] Furthermore, the supporting bridge frame and the climbing section are integrally formed, so that when the bridge frame is installed, it is only necessary to connect the climbing section and the main bridge frame, which effectively improves the installation efficiency.

[0009] Furthermore, the supporting bridge frame and the climbing section are connected by welding, which is easy to implement.

[0010] Furthermore, the climbing section and the main bridge are connected by welding, which is easy to implement.

[0011] On the other hand, the present invention provides a method for manufacturing a spanning cable tray structure, characterized in that the manufacturing of the spanning cable tray structure as described above comprises the following steps:

[0012] Step S1, determining the climbing angle of the cable tray accessories according to actual conditions;

[0013] Step S2, complete the BIM modeling of all electromechanical disciplines according to the electromechanical design blueprint, and complete the comprehensive deepening of electromechanical pipelines and the bridge span connection design based on the BIM model of all electromechanical disciplines using the spanning cable bridge structure as described in any one of claims 1 to 5, and clarify the specifications, span heights and specific locations of the main bridge and branch bridge;

[0014] Step S3, export the bridge accessories and climbing section list according to the improved bridge BIM model, and the export parameters should include: main bridge specifications, supporting bridge specifications, and span height;

[0015] Step S4, manufacturing the required bridge accessories and climbing sections according to the specifications, span heights and quantities of the main / branch bridges derived from the detailed list;

[0016] Step S5: Install and fix the designed bridge structure and cable laying on site.

[0017] The bridge structure manufacturing method of the present application is based on the premise of using the above-mentioned spanning cable bridge structure to carry out comprehensive deepening of electromechanical pipelines and bridge span connection design based on the full electromechanical professional BIM model. The overall planning of the design scheme provides a guarantee for the implementation of a simple bridge structure.

[0018] Furthermore, in step S4, the support bridge and the climbing section are prefabricated and numbered as a whole during the processing stage; in step S5, the support bridge is installed at the corresponding position according to the number. This technical feature increases the prefabrication ratio of the spanning cable bridge construction, thereby improving the construction efficiency.

[0019] Compared with the prior art, the above invention has the following advantages or beneficial effects:

[0020] (1) Since the bridge structure of the present invention does not require additional connecting parts, it can reduce the space required for accessories to avoid each other at the concentrated area, thereby reducing the difficulty of installing the support brackets and the bridge.

[0021] (2) During the cable laying process, there is a large friction resistance between the cable and the bridge. When the bridge accessories avoid each other and bend, the resistance to the cable will increase sharply, greatly increasing the difficulty of laying. Therefore, it is necessary to increase labor input or extend the cable laying period. The increased resistance makes the cable susceptible to damage during laying. The bridge structure of the present invention can effectively reduce the number of bridge bends, reduce the difficulty and cost of cable laying, reduce cable damage, and make the layout more beautiful because the layout of the main / branch bridges is designed through the overall design of the BIM model.
