Description

Technical Field

[0001] The invention relates to the technical field of beam string corridors, in particular to a low-position corridor with a spatial beam string-hollow truss steel structure. Background Art

[0002] In urban life, in order to meet people's needs for convenient passage between buildings, the application of large-span corridors is becoming increasingly common. In order to control the deflection of the corridor, one approach is to set support columns connected to the ground under the corridor. However, the setting of support columns increases the amount of steel used, interferes with ground passage, and sometimes makes the building structure lack flexibility, affecting the architectural effect.

[0003] At present, the common large-span corridors in the prior art are generally pulled by a plane tensioned beam structure. Due to the lack of constraints outside the plane, the spatial stability is poor, and the connection nodes between the struts and the cables are subjected to large forces. The fixed connection structure is easily loosened under the action of external forces, resulting in a poor pulling effect. Moreover, the connection nodes are always exposed to the outside, and moisture or dust can easily enter the connection nodes, which can easily cause some metal parts in the nodes to rust and corrode due to moisture. When the connection nodes are vibrated, not only are the connection parts easy to loosen, but the vibration cannot be buffered, causing the nodes to be easily damaged by vibration.

[0004] In order to solve the design difficulties of large-span corridor structures, such as overall structural flexibility, weak rigidity and difficulty in comprehensive protection of connection nodes due to excessive span, the present invention proposes a low-position corridor with a spatial tensioned beam-hollow truss steel structure.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The low-position corridor of the spatial beam string-hollow truss steel structure can form a self-balancing beam string support mechanism by assembling a middle support assembly at the middle of the lower part of the truss corridor, connecting cables on both sides of the middle support assembly, and connecting the other end of the cable to the lower end of the truss corridor. Since the cables are installed at the lower part of the truss corridor, the technology can further enhance the rigidity and strength of the truss corridor, and by applying pre-tension stress to the cables on both sides, the deflection of the corridor can be effectively controlled to ensure that the corridor maintains better stability when bearing loads, so that the truss corridor has outstanding seismic performance and ensures the safety of the building. In addition, the technology adopts a modular design, which makes the assembly and disassembly process of the truss corridor faster and more efficient. At the same time, the technology has strong versatility and variability, can adapt to different architectural styles and functional requirements, and provides great convenience for engineering implementation;

[0024] 2. The low-position corridor of the space string beam-hollow truss steel structure can be separated from the assembly seat by splitting the sealing structure into an upper press-fit assembly and a lower press-fit assembly, thereby avoiding affecting the construction of the cable, and the detachable setting is convenient for disassembly and assembly. Secondly, the upper half shell and the lower half shell are butt-jointed and assembled with a nut and a screw thread, so that the upper half shell and the lower half shell can be sealed. At the same time, the butt-jointing process can pressurize the first airbag and the third airbag, so that the gas is filled into the second airbag. In the fourth airbag, due to the U-shaped arrangement of the second airbag and the fourth airbag, the second airbag is expanded to enclose the outer periphery of the cable and fill the first side opening. Similarly, the fourth airbag is enclosed around the support rod and fills the second side opening, thereby improving the sealing of the upper half shell and the lower half shell, thereby avoiding corrosion of the internal connection nodes to affect the reinforcement effect and the service life. Secondly, after the upper half shell and the lower half shell are butt-jointed, the gear rod is meshed with the gear, thereby locking the first bolt to prevent the node from loosening and affecting the pulling reinforcement effect;

[0025] 3. The low-level corridor of the spatial tensioned beam-hollow web truss steel structure maintains a closed connection between the upper half shell and the lower half shell by docking them and threading them with a nut and a screw. At this time, silicone mixed with reinforcing material is injected through the injection port to fill the cavity formed by the upper half shell and the lower half shell with silicone to form it so that the silicone can cover the node to achieve the effect of secondary sealing. Since silicone has good waterproof performance, it can effectively prevent moisture from entering the connection node to avoid rust and corrosion of metal parts inside the node due to moisture. In addition, silicone has strong weather resistance and can maintain its protective performance for a long time, thereby extending the service life of the node. In addition, adding reinforcing material to silicone can effectively improve the strength of silicone. Secondly, silicone has a certain elasticity. When the node is vibrated or impacted, it can also play a buffering role to reduce damage to the node, thereby further improving the strength of the node and increasing its service life.

Moreover, this technology adopts a modular design, which makes the assembly and disassembly process of the truss corridor 100 faster and more efficient. At the same time, this technology has strong versatility and variability, can adapt to different architectural styles and functional requirements, and provides great convenience for engineering implementation.

Secondly, after the upper half shell 3051 and the lower half shell 3032 are connected, the gear rod 3034 is meshed with the gear 3024, thereby locking the first bolt 3023 to prevent the node from loosening and affecting the pulling reinforcement effect.

In addition, the silicone 306 has strong weather resistance and can maintain its protective performance for a long time, thereby extending the service life of the node. In addition, adding the reinforcing material 304 to the silicone 306 can effectively improve the strength of the silicone 306. Secondly, the silicone 306 has a certain elasticity. When the node is vibrated or impacted, it can also play a buffering role to reduce damage to the node, thereby further improving the strength of the node and improving its service life.

Similarly, the fourth airbag 3055c is enclosed on the support rod 3011, and the second side opening 3056 is closed to complete the sealing. Then, silicone 306 mixed with reinforcing material 304 is injected into the cavity enclosed by the upper half shell 3051 and the lower half shell 3032 through the injection port 3054 to fill the node to complete the construction work.
