Description

Technical Field

[0001] The present invention relates to the field of steel structures, and particularly relates to a large-span arc-shaped steel structure with enhanced protection. Background Art

[0002] Steel structures spanning 60 meters horizontally, concrete structures with a span of over 30m, and frame structures with a span of over 18m are large-span steel structures. Their structural forms mainly include five major spatial structures such as grid structures, latticed shell structures, cable structures, membrane structures, and thin-shell structures, as well as various combined spatial structures.

[0003] In architecture, there are many large-span steel structures, especially horizontally arc-shaped steel structures. Due to the large span, there will be an outward-turning force, which will cause the overall arc-shaped steel frame to become loose or deformed, affecting the overall load-bearing capacity of the arc-shaped steel structure. Generally, ropes are used to pull it, but the ropes still need to find positioning points, which is rather troublesome. Due to its large span, the positioning effect will also be affected when using ropes for positioning. Therefore, the inventor has invented and created a large-span arc-shaped steel structure with enhanced protection to solve the load-bearing problem of the arc-shaped steel structure. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and provide a large-span arc-shaped steel structure with enhanced protection.

[0005] The present invention is achieved through the following technical solutions:

[0006] A large-span arc-shaped steel structure with enhanced protection, including a steel structure. Connecting rods are symmetrically installed on the right end face of the steel structure. An installation plate is fixedly installed at the right end of the connecting rods. Screw rings are evenly welded on the surface of the steel structure. Plug plates are evenly installed on the surface of the steel structure. A connecting block is welded on the outer surface of the plug plate. A second fastening screw is installed between the connecting block and the steel structure. First rotating tubes are symmetrically sleeved inside the plug plates. A plug rod is installed between the first rotating tube and the plug plate. A first fastening screw is installed between the plug rod and the plug plate. A second rotating tube is provided inside the first rotating tube. A sliding rod is installed between the second rotating tube and the first rotating tube. A third fastening screw is installed between the sliding rod and the first rotating tube. A counterweight ball is fixedly installed at the end of the second rotating tube.

[0007] Preferably, the steel structure is an arc-shaped structure.

[0008] Preferably, a through groove for the rotation of the first rotating tube is opened inside the plug plate.

[0009] Preferably, the cross-section of the plug rod is a regular hexagon.

[0010] Preferably, the sliding rod is fixedly connected to the second rotating tube and the sliding rod is inserted into the first rotating tube.

[0011] Preferably, the counterweight ball is of a steel ball structure and is solid inside.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] In the present invention, a plurality of vertical insertion plates are arranged on the arc-shaped steel structure, and the counterweight balls are adjusted on the insertion plates. The counterweight of the counterweight balls applies a force to the steel structure in the middle direction, so as to facilitate the control of the force applied to the steel structure, prevent the steel structure from turning outwards or deforming, replace the connection of the towing rope, and is more convenient to install. By setting the sliding rod, the overall length of the first rotating pipe and the second rotating pipe can be adjusted, and the position of the counterweight ball can be adjusted and controlled. By setting the insertion rod, the rotation angle of the rotating pipe can be adjusted, so that the counterweight condition of the counterweight ball can be controlled. The present invention arranges a plurality of insertion plates and sets counterweight balls on the insertion plates, so that the counterweight balls can apply a force to the arc-shaped steel structure in the middle, further preventing the steel structure from turning outwards and strengthening the protection of the steel structure.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-2 , the present invention provides a technical solution:

[0019] A large-span arc-shaped steel structure with enhanced protection, including a steel structure 8. On the right end face of the steel structure 8, connecting rods 9 are symmetrically installed. At the right end of the connecting rod 9, a mounting plate 10 is fixedly installed. On the surface of the steel structure 8, screw rings 7 are evenly welded. On the surface of the steel structure 8, plug plates 6 are evenly installed. On the outer surface of the plug plate 6, a connecting block 4 is welded. Between the connecting block 4 and the steel structure 8, a second fastening screw 5 is installed. Inside the plug plate 6, first rotating tubes 3 are symmetrically sleeved. Between the first rotating tube 3 and the plug plate 6, a plug rod 2 is installed. Between the plug rod 2 and the plug plate 6, a first fastening screw 1 is installed. Inside the first rotating tube 3, a second rotating tube 13 is provided. Between the second rotating tube 13 and the first rotating tube 3, a sliding rod 12 is installed. Between the sliding rod 12 and the first rotating tube 3, a third fastening screw 11 is installed. At the end of the second rotating tube 13, a counterweight ball 14 is fixedly installed.

[0020] The steel structure 8 is an arc-shaped structure.

[0021] Inside the plug plate 6, a through groove for the rotation of the first rotating tube 3 is opened.

[0022] The cross-section of the plug rod 2 is a regular hexagon.

[0023] The sliding rod 12 is fixedly connected to the second rotating tube 13, and the sliding rod 12 is inserted into the first rotating tube 3.

[0024] The counterweight ball 14 is a steel ball structure and is solid inside.

[0025] Operation steps: The steel structure 8 is an arc-shaped steel structure. Multiple plug plates 6 are installed on the steel structure 8, and the plug plates 6 are fixed on the steel structure. By adjusting the plug rod 2, the angles of the first rotating tube 3 and the second rotating tube 13 are adjusted. The first fastening screw 1 is used to position the plug rod 2. By adjusting the third fastening screw 11, the sliding rod 12 can be adjusted outwards, which is equivalent to adjusting the lever arm of the counterweight ball 14. After adjusting the counterweight ball 14, the counterweight ball 14 provides a pressure towards the middle to the steel structure, preventing the steel structure from turning outwards, thereby protecting the steel structure 8. In this way, the large-span steel structure will not be affected by the external wind force and the gravity of the steel structure itself, replacing the connection of the traction rope and making the control more convenient.

[0026] This specific embodiment is only an explanation of the present invention and not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
