Description

Technical Field

[0001] This utility model belongs to the field of building structure and power facility installation technology, specifically a roof grid cable bridge beam device. Background Technology

[0002] Space frame structures are widely used in the roof systems of large industrial plants, stadiums, and other public buildings. To lay various types of cables, including high-voltage and low-voltage cables, cable trays need to be installed beneath the space frame. Traditional cable tray installation typically uses hanger and support systems, making the installation of cable trays inside a roof space frame structure somewhat challenging.

[0003] However, the existing cable tray installation methods still have the following problems when applied to space frame structures:

[0004] The unique characteristics of roof space frame structures and the high-altitude working environment make it difficult to implement traditional hanging rod and bracket installation methods. It is hard to find suitable fixing points, resulting in low construction efficiency and high risks.

[0005] Welding or drilling holes directly onto the grid structure components to install hanging brackets may potentially affect the overall structural strength and stability of the grid structure, posing a safety hazard.

[0006] To address the aforementioned issues, it is necessary to design a cable tray installation device specifically suited for grid structures, based on existing installation methods. This device should ensure that the safety of the grid structure is not affected, while also enabling flexible and convenient installation. Utility Model Content

[0007] The purpose of this utility model is to provide a roof grid cable tray beam device to solve the problems mentioned in the background art, such as difficulty in installing cable trays on grid structures, poor adaptability, and impact on structural safety.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a roof grid cable tray beam device, comprising a lower chord, a lower ball joint, a web member, an upper ball joint, an upper chord, a short column, a bracket, a beam, a cable tray, connecting bolts, and cables. The lower ball joint, lower chord, web member, upper ball joint, and upper chord are connected by threads to form a roof grid system;

[0009] A short column is welded to the top of the lower ball node, a bracket is welded to the top of the short column, a crossbeam is welded between two adjacent brackets, and a cable tray is installed on the crossbeam.

[0010] The crossbeam is fixedly connected to the cable tray by connecting bolts, and the cable is laid inside the cable tray.

[0011] Preferably, the short column is a support member vertically welded to the top of the lower ball node.

[0012] Using the above technical solution, the short columns serve as the foundation of the load-bearing structure, transferring the load to the space frame system.

[0013] Preferably, the support is a horizontal load-bearing platform welded to the top of the short column.

[0014] Using the above technical solution, the support is used to support and position the crossbeam.

[0015] Preferably, the crossbeam is a horizontal support beam with both ends welded between adjacent supports.

[0016] Using the above technical solution, the crossbeam enables load transfer between adjacent supports and provides an installation base for the cable tray.

[0017] Preferably, the cable tray is detachably fixed to the crossbeam by connecting bolts.

[0018] By adopting the above technical solution, the connecting bolts enable a reliable connection between the cable tray and the crossbeam, and facilitate convenient assembly and disassembly.

[0019] Preferably, the cable tray is used to accommodate and secure cables.

[0020] Using the above technical solution, cable trays provide a laying channel and protection for cables.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Easy and efficient installation: By directly welding short columns, brackets and crossbeams to the lower ball joint to form a support system, there is no need for complicated hanging bracket installation, which greatly simplifies the construction process and shortens the construction period.

[0023] The welded connection method ensures that the short columns, supports, beams, and space frame nodes form a rigid whole, significantly improving the stability and load-bearing capacity of the cable tray installation and guaranteeing safety. The device has a simple and lightweight structure, and the height of the short columns, the position of the supports, and the length of the beams can be flexibly adjusted according to different space frame sizes and cable tray specifications to meet various span requirements. Welding to the lower ball joints avoids drilling or welding on the space frame members, maximizing the protection of the integrity and safety of the main space frame structure. The beams provide a stable installation platform, and the cable trays are quickly fixed with bolts, facilitating cable laying and maintenance. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2 This utility model provides a technical solution: a roof grid cable tray crossbeam device, comprising a lower chord 1, a lower ball joint 2, a web member 3, an upper ball joint 4, an upper chord 5, a short column 6, a support 7, a crossbeam 8, a cable tray 9, connecting bolts 10, and a cable 11. The lower ball joint 2, lower chord 1, web member 3, upper ball joint 4, and upper chord 5 are connected by threads to form a roof grid system.

[0029] Combination Figure 1 As shown, a short column 6 is vertically welded to the top of the lower ball node 2, a bracket 7 is horizontally welded to the top of the short column 6, and a crossbeam 8 is horizontally welded between two adjacent brackets 7. The cable tray 9 is connected and fixed on the crossbeam 8 by connecting bolts 10. Finally, the cable 11 is laid in the cable tray 9 and firmly fixed.

[0030] The working principle of this utility model is as follows: During installation, short columns 6, brackets 7, and crossbeams 8 are first prefabricated in the factory or on-site. After precise leveling at the top of the lower ball node 2 of the assembled space frame structure, the short columns 6 are welded. Brackets 7 are welded to the top of the short columns 6, ensuring the top surface of the brackets 7 is level. Crossbeams 8 are welded between adjacent brackets 7 to form a stable support system. The cable tray 9 is then hoisted and placed on the crossbeams 8. After adjusting its position until the deviation meets the installation standards, the cable tray 9 is firmly fixed to the crossbeams 8 using connecting bolts 10. Finally, the cables 11 are laid in the installed cable tray 9 and fixed. This device directly fixes the support system (short columns 6, brackets 7, and crossbeams 8) to the space frame node (lower ball node 2) by welding, eliminating the need for drilling holes or welding hangers on the space frame members. This makes installation convenient, efficient, and the structure stable and reliable.
