Description

Technical Field

[0001] This utility model relates to the technical field of steel structure devices, specifically a prestressed cable-reinforced steel structure beam. Background Technology

[0002] With the booming development of the construction industry, the performance requirements for building structures are increasing. Among various building structures, steel beams are widely used in large-span buildings, such as stadiums, convention centers, and airport terminals, due to their advantages of high strength, light weight, and convenient construction. However, traditional steel beams often have limitations in stiffness and load-bearing capacity when facing large spans or heavy loads, making it difficult to meet increasingly complex building functions and safety standards. The emergence of prestressed technology provides an effective way to solve this problem. By incorporating prestressed cables into the steel beam system and applying prestress to the cables, additional support force and reverse bending moment can be provided to the steel beam, effectively improving the stress state of the steel beam and significantly enhancing its load-bearing capacity and stiffness. This type of prestressed cable-reinforced steel beam has a clear and reasonable force path, saving steel consumption while reducing structural deformation and improving structural stability and seismic performance. At present, although prestressed steel structures have been applied in many large buildings, there is still room for improvement in the research on the collaborative working mechanism of prestressed cables and steel beams, the long-term performance monitoring and maintenance of cables, and how to further optimize structural design to adapt to different building environments and functional requirements. These areas urgently need in-depth research and innovation.

[0003] Application number CN201620116910.0 discloses a steel structure beam, characterized by comprising a sleeve and an inner sleeve. The sleeve has a sleeve wall that forms a sleeve cavity. A first through groove is provided on the sleeve wall, penetrating the sleeve wall and communicating with the sleeve cavity. An inner sleeve is provided inside the sleeve cavity and connected to the sleeve wall. The inner sleeve extends along the length of the sleeve. The steel structure beam of this invention features a first through groove on the sleeve wall, facilitating the insertion of a welding device into the cavity to weld the sleeve wall to other structures. It also allows for a large welding area and long weld seam, ensuring a stable weld connection. However, a drawback is that the device is not yet designed to handle vibrations encountered during use, leading to instability and potential safety hazards. Utility Model Content
