Description

Technical Field

[0001] This application relates to the technical field of steel structures, and in particular to a steel space frame structure base. Background Technology

[0002] The steel space frame structure base is a core load-bearing component of large-scale spatial buildings, used to connect the space frame nodes and foundation supports, and undertaking the functions of load transfer, vibration attenuation, and deformation coordination. Currently, the engineering field commonly adopts base designs with welded or high-strength bolted rigid connections, relying on the inherent rigidity of the metal structure to resist external dynamic and static loads. As large-span buildings develop towards lightweighting, enhanced seismic performance, and prefabricated construction, the market demands increasingly stringent requirements for the base's vibration damping redundancy, on-site installation tolerance, and long-term service stability, driving the upgrade of base technology towards flexible, adjustable, integrated structures.

[0003] Firstly, the rigid connection interface lacks an effective buffer medium. Under the periodic impact caused by wind vibration, earthquake or equipment operation, stress concentration can easily lead to weld cracking or bolt fatigue fracture, resulting in degradation of the overall structural stiffness or even sudden failure.

[0004] Secondly, fixed flange connections rely on high-precision prefabricated components, making it difficult to compensate for foundation elevation deviations or thermal expansion and contraction deformation of the space frame at the construction site. Forced corrections can easily cause localized stress exceeding limits or gasket tearing, requiring repeated disassembly and adjustment, significantly extending the construction period and increasing construction costs. In addition, existing base vibration damping modules are mostly designed separately from the connection mechanism, allowing vibration energy to spread through a rigid force transmission path, exacerbating the risk of high-frequency resonance in the structure. Furthermore, traditional rubber vibration isolation pads are prone to creep aging due to long-term pressure, further weakening the system's durability and dynamic response performance.

[0022] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0023] This application discloses a steel space frame structure base. For example... Figure 1 As shown, the main body (1) includes a space frame structure (2), and a fixing structure (4) is fixedly installed below the space frame structure (2). The fixing structure (4) is provided with a hinge support structure (3) inside.

[0024] The space frame structure (2) includes a bolt ball (201), and a bolt frame (202) is fixedly connected below the bolt ball (201);

[0025] The hinge structure (3) includes an upper concave groove (301), an I-shaped block (302) is provided inside the upper concave groove (301), a lower concave groove (303) is provided below the I-shaped block (302), and a rubber pad (304) is provided outside the lower concave groove (303).

[0026] It should be noted that the main body (1) integrates the space frame structure (2), the fixed structure (4), and the hinged support structure (3) to achieve synergistic effects. The space frame structure (2) is formed by welding bolt balls (201) and bolt frames (202) to form a spatial truss, providing stable rigid support and adapting to the complex loads of large-span buildings; the fixed structure (4) simplifies installation and enhances the rigid connection with the foundation through the bolt connection of the upper flange 401 and the lower flange 402 and the reserved gap; the hinged support structure (3) utilizes the sliding fit of the upper concave groove (301), the I-shaped block (302), and the lower concave groove (303), combined with the elastic buffer of the rubber gasket (304), to achieve multi-directional displacement adjustment and vibration energy absorption, reduce stress concentration, and improve seismic performance. The overall design takes into account structural stability, installation flexibility, and vibration damping durability, effectively extending the life of the base.

[0027] The fixed structure (4) includes an upper flange (401), and a lower flange (402) is movably connected below the upper flange (401).

[0028] It should be noted that the fixed structure (4) achieves a rigid connection and flexible adjustment between the base and the foundation through the movable connection of the upper flange (401) and the lower flange (402) and the bolt fixing design. The reserved adjustment gap allows for fine-tuning under different installation conditions, ensuring precise fit between the base and the foundation, while the bolt fixing enhances the stability of the overall structure. This design simplifies the installation process, improves construction efficiency, and effectively disperses external load stress, reducing structural deformation caused by environmental changes or dynamic loads, thereby improving the durability and deformation resistance of the base.

[0029] The upper flange (401) and the lower flange (402) are fixedly connected by bolts, and an adjustment gap is reserved to adapt to different installation conditions.

[0030] It should be noted that the upper flange 401 and the lower flange 402 are fixedly connected by bolts, and the purpose of reserving an adjustment gap is to ensure the stability of the upper flange 401 and the lower flange 402 through the bolt connection, while utilizing the reserved adjustment gap to adapt to the fine-tuning needs under different installation conditions. This not only enhances the structural rigidity, but also improves the installation flexibility and environmental adaptability, effectively copes with dynamic factors such as construction errors and temperature deformation, thereby improving the overall stability and durability of the base.

[0031] The bolt frame (202) and the bolt ball (201) are connected by welding to form a stable space frame support system.

[0032] It should be noted that the bolt frame (202) and the bolt ball (201) are connected by welding to form a stable spatial grid support system. The purpose of this connection is to utilize the high-strength bonding characteristics of welding to ensure the firmness of the node connections, preventing loosening or displacement, thereby constructing a rigid support frame in three-dimensional space. This design effectively distributes loads, enhances the overall structure's resistance to deformation, and provides reliable foundation support for the upper hinged structure 3 and fixed structure 4, strengthening the stability of the base under dynamic loads or complex stress conditions, ultimately ensuring the safety and durability of the steel grid system.

[0033] The rubber pad (304) is a multi-layer composite elastic material used to absorb external vibration energy.

[0034] It should be noted that the rubber gasket (304) is made of multi-layer composite elastic material. Its main function is to effectively absorb and disperse external vibration energy through its elastic properties, reduce the impact of dynamic loads on the steel space frame structure 2 base, thereby reducing stress concentration and structural fatigue, enhancing overall seismic performance and extending service life. Its design, combined with the sliding fit of the hinged support structure 3, further realizes multi-directional buffer adjustment, ensuring the stability and durability of the base under complex working conditions.

[0035] The bottom of the recessed groove (303) is provided with a drainage hole to prevent water accumulation from corroding the hinged structure (3).

[0036] It should be noted that the drainage holes provided at the bottom of the recessed groove (303) are mainly used to drain the water accumulated in the hinge structure (3), so as to avoid corrosion of metal parts due to long-term water accumulation, thereby ensuring the durability and functional stability of the hinge structure 3 and extending the service life of the overall base.

[0037] A buffer gap is reserved between the I-shaped block (302) and the upper concave groove (301).

[0038] It should be noted that the buffer gap reserved between the I-shaped block (302) and the upper concave groove (301) allows the I-shaped block 302 to produce a small displacement when subjected to force. By dispersing the external load through multi-directional adjustment, the stress concentration caused by rigid contact is reduced. At the same time, the elastic properties of the rubber gasket 304 further absorb vibration energy, thereby improving the seismic performance, adaptability and durability of the structure, and reducing the risk of structural fatigue under dynamic loads or seismic action.

[0039] The implementation principle of a steel space frame structure base in this application embodiment is as follows:

[0040] The main structure 1 is composed of three parts: a space frame structure 2, a hinged support structure 3, and a fixed structure 4. The space frame structure 2 forms a spatial truss support system by welding bolt balls 201 to bolt frames 202. The bolt balls 201 serve as nodes connecting the bolt frames 202. The welding process ensures the robustness of the nodes, providing stable rigid support for the overall structure and adapting to the complex load requirements of large-span buildings. The hinged support structure 3 is integrated inside the fixed structure 4 and consists of an upper concave groove 301, an I-shaped block 302, a lower concave groove 303, and a rubber gasket 304. The I-shaped block 302 is embedded in the upper concave groove 301 and slides with the lower concave groove 303 below. A multi-layered composite elastic material rubber gasket 304 is installed on the outside, absorbing external vibration energy through reserved buffer gaps and elastic deformation, achieving multi-directional displacement adjustment and efficient vibration reduction. The fixed structure 4 adopts a movable connection design between the upper flange 401 and the lower flange 402. The two are fixed by bolts and an adjustment gap is reserved to allow for fine adjustment under different foundation conditions, ensuring precise fit between the base and the foundation, while enhancing the overall rigid connection.

[0041] During installation, the bolt ball 201 and bolt bracket 202 are first welded to form the main frame 1 of the space frame structure 2. Then, the hinged support structure 3 is assembled into the fixed structure 4: the I-shaped block 302 is embedded into the upper concave groove 301, and a rubber gasket 304 is installed on the outside of the lower concave groove 303. A drainage hole is provided at the bottom to prevent water accumulation and corrosion. The upper flange 401 and lower flange 402 of the fixed structure 4 are connected by bolts. After adjusting the gap, they are tightened to ensure a stable connection between the base and the foundation. The buffer gap between the I-shaped block 302 and the upper concave groove 301, combined with the elastic properties of the rubber gasket 304, further disperses dynamic loads and absorbs vibrations. Finally, the welded joints, bolt connections, and drainage hole conditions are checked to ensure the overall structure works in harmony.

[0042] The base significantly enhances its resistance to deformation and seismic performance through the rigid support of the space frame structure 2, the elastic buffering of the hinged support structure 3, and the flexible adjustment of the fixing structure 4. Rubber gaskets 304 effectively reduce stress concentration, drainage holes extend the structural lifespan, and the adjustable flange clearance enhances environmental adaptability. The overall design simplifies the installation process, making it suitable for large-span buildings and high-stability engineering scenarios. It maintains high safety and durability under dynamic loads or seismic action, meeting the needs of complex engineering projects.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
