Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and more particularly to a node mechanism for beam cables. Background Technology

[0002] Tensioned beam structures are a hybrid structural system consisting of a rigid upper chord, flexible cables, and intermediate struts. Their structural composition is a novel self-balancing system, a large-span prestressed spatial structure, and a relatively successful innovation in the development of hybrid structural systems. Tensioned beam structures are simple, have clearly defined stress distribution, offer diverse structural forms, fully utilize the advantages of both rigid and flexible materials, and are easy to manufacture, transport, and construct, thus possessing promising application prospects.

[0003] Therefore, in the construction of tensioned beam structures, appropriate tools are needed to assemble and connect the cables and steel structures. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a node mechanism for a beam cable, comprising two cable ends and cable members disposed on the cable ends. Each cable end includes a placement section with a receiving groove in the middle. The cable member includes a screw, one end of which is fixedly connected to a limiting block, which engages within the receiving groove. During use, if the cable member experiences wear, the limiting block and receiving groove facilitate replacement.

[0005] Two clamping plates are clamped onto the screw. Each clamping plate includes a plate body with a first groove, and the screw is disposed in the first groove. A limit nut is threaded onto the screw, with one end of the limit nut abutting against one side of the clamping plate. This structure is used to connect a fixed plate and a cable. The clamping plates simultaneously hold the screw and the cable, and the cable end is then fixedly connected to the fixed plate. By rotating the limit nut, the cable is pushed to the fixed plate, and then bolts, pins, and other components are used to interlock and fix the fixed plate and the cable.

[0006] Preferably, a cover plate is provided on one side of the placement section, and a second bolt is provided through each of the four corners of the cover plate. The second bolts are threaded onto the placement section. The cover plate is fixed to the placement section by the second bolts.

[0007] Preferably, one end of the placement section has an open section, and a first bolt is inserted through the open section. The open section and the first bolt facilitate the insertion and fixing of the cable end to the fixing plate.

[0008] Preferably, the sidewall of the first groove is provided with ribs to improve the structural strength of the first groove.

[0009] Preferably, the plate has a through hole, and a third bolt is inserted through the through hole to connect and fix the two plates.

[0010] Preferably, a second groove is formed in the middle of the plate. The second groove is for accommodating the cable.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. Limiting blocks and receiving slots are provided to facilitate the assembly and use of cable ends and cable components, and also to facilitate the replacement of cable components.

[0013] 2. Ribs are provided on the side wall of the first groove, which improves the structural strength of the first groove. At the same time, the entire device is connected and fixed by bolts, which facilitates disassembly and assembly. Attached Figure Description

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figures 1 to 3As shown, a node mechanism for a beam cable includes two cable ends 2 and a cable member 3 disposed on the cable ends 2. The cable end 2 includes a placement section 24, and a receiving groove 23 is provided in the middle of the placement section 24. The cable member 3 includes a screw 32, one end of which is fixedly connected to a limiting block 31. The limiting block 31 is fitted in the receiving groove 23. The limiting block 31 has a cuboid structure, which facilitates placement in the receiving groove 23. With this connection method, the cable member 3 is disposed on the cable end 2 conveniently and quickly.

[0022] Two clamping plates 5 are clamped on the screw 32. Each clamping plate 5 includes a plate body 51. A first groove 52 is provided on the plate body 51, and the screw 32 is disposed in the first groove 52. A limit nut 6 is threadedly connected to the screw 32, and one end of the limit nut 6 abuts against one side of the clamping plate 5.

[0023] This device is used to connect the fixed plate 1 and the cable 4. First, the cable 4 and the screw 32 are clamped and held together by the clamping plate 5, while ensuring that the clamping plate 5 can slide on the cable 4 and the screw 32. Then, the cable end 2 is connected to the fixed plate 1. At this time, by rotating the limiting nut 6, the cable 4 is pushed to the fixed plate 1. When the preset through holes on the fixed plate 1 and the cable 4 are aligned, bolts, pins and other connecting parts can be used to insert and fix the fixed plate 1 and the cable 4.

[0024] A cover plate 21 is provided on one side of the placement section 24. The cover plate 21 is a plate piece. A second bolt 22 is provided through each of the four corners of the cover plate 21. The second bolt 22 is threaded onto the placement section 24. The cover plate 21 is fixedly connected by the second bolt 22, thereby keeping the limiting block 31 in the receiving groove 23.

[0025] One end of the placement section 24 is provided with an opening section 25. When in use, the opening section 25 clamps the fixing plate 1. A first bolt 7 is inserted through the opening section 25, and the two are connected and fixed by the first bolt 7.

[0026] The sidewall of the first groove 52 is provided with ribs 53. The ribs 53 are used to improve the structural strength of the first groove 52.

[0027] The plate 51 has a through hole, and a third bolt 54 is inserted through the through hole. The third bolt 54 is used to clamp and fix the two clamping plates 5.

[0028] A second groove 55 is provided in the middle of the plate 51. The second groove 55 is used to accommodate the cable 4.
