[0002] In the field of structural support for long-span buildings, traditional support structures often employ on-site welding or assembly of large prefabricated components. This approach not only has a long construction cycle and high costs, but also imposes strict requirements on site conditions, especially in complex terrain or under limited construction conditions, where the limitations of traditional methods become more pronounced. Furthermore, traditional structures are insufficient in their seismic and wind resistance to natural disasters such as earthquakes and strong winds, making them prone to structural damage and affecting the safety and lifespan of the building.
[0003] In recent years, with the innovation of building materials and the optimization of structural design, modular and pre-assembled technologies have been widely used in the support structures of long-span buildings. Steel space frame structures, in particular, with their lightweight and high strength, can meet the needs of large-span covered supports, while also possessing good economic efficiency and ease of construction. However, existing steel space frame structures still need improvement in connection methods, fixing methods, and seismic performance, especially in the stability of connections, the convenience of rapid installation, and the ability to resist dynamic external forces.
[0004] To address the aforementioned issues, this patent proposes an innovative steel space frame structure design. This design significantly improves the installation efficiency, structural stability, and resistance to external forces of the steel space frame structure by optimizing the plug-in connection method, introducing locking and fixing devices, a deformation buffer and limiting reinforcement system, and elastic limiting and energy absorption design. This design not only simplifies the on-site construction process and reduces construction costs, but also enhances the safety and durability of large-span building support structures, providing a more efficient and reliable solution for the modern construction field.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides, for example Figures 1-5 The diagram illustrates a large-span steel space frame structure that is easy to install and use. It includes multiple connecting frames 1, each with a connecting plug 2 fixedly connected to its rear center. Each connecting frame 1 also has a connecting slot 3 inside its front center, and the multiple connecting frames 1 are interconnected via the connecting plug 2 and the connecting slot 3. Each connecting frame 1 has a threaded fixing bolt 4 threaded to its right front side, and the connecting plug 2 is fixed inside the connecting slot 3 by the fixing bolt 4. In modern architecture, steel space frames are commonly used for large-span coverage and support. The steel space frame is assembled from multiple connecting frames 1. During the front-to-back connection of the multiple connecting frames 1, they are interconnected via the insertion of the connecting plug 2 and the connecting slot 3, and fixed by the fixing bolt 4. After the front-to-back connection of the multiple connecting frames 1, a transverse connecting mechanism assembles the multiple front-to-back connected connecting frames 1 together, thus forming the steel space frame.
[0028] Preferably, a telescopic groove 15 is provided inside the center of the right inner wall of the connecting slot 3, and the left end of the fixing bolt 4 protrudes into the telescopic groove 15. A locking slider 16 is slidably connected inside the telescopic groove 15, and the left end of the locking slider 16 protrudes into the connecting slot 3. The fixing bolt 4 is tightly fitted to the center of the right end of the locking slider 16. Return springs 17 are provided at the four corners between the locking slider 16 and the left inner wall of the telescopic groove 15, and the right ends of the four return springs 17 are located inside the locking slider 16. A locking slot 18 is provided inside the right end of the connecting plug 2, and the left end of the locking slider 16 is engaged in the locking slot 18. Return springs 17 are provided at the four corners between the slider 16 and the inner wall of the left end of the telescopic slide 15. Therefore, the locking slider 16 can be completely retracted into the telescopic slide 15 under the action of the return springs 17, allowing the connector 2 to be smoothly inserted into the connector slot 3. When the fixing bolt 4 fixes the connector 2, the fixing bolt 4 is screwed to the left and pushes the locking slider 16 to slide to the left inside the telescopic slide 15, so that the left end of the locking slider 16 protrudes into the connector slot 3 and is locked into the locking slot 18, and fits tightly with the locking slot 18, thereby fixing the connector 2 and ensuring the stable connection between multiple connectors 1.
[0029] Preferably, the connecting frame 1 has a reinforcing limiting groove 5 on both the upper and lower sides of its rear end, and a fixing groove 11 with an upward opening on both the upper and lower sides of its front end. The two fixing grooves 11 are located on the upper and lower sides of the connecting slot 3, respectively. The front ends of the two fixing grooves 11 are fixedly connected to fixing blocks 12 by bolts. The front end of the fixing blocks 12 is fixedly connected to a deformation buffer plate 13 near the connecting slot 3. The deformation buffer plate 13 is inserted into the reinforcing limiting groove 5 and fits against the inner wall of the reinforcing limiting groove 5 near the connecting plug 2. The two limiting clips 8 are respectively engaged in the two limiting clip slots 14. After connecting multiple connecting frames 1, the connection is reinforced by the deformation buffer plates 13 set at the upper and lower ends of the multiple connecting frames 1. The deformation buffer plates 13 are fixedly connected to the front end of the connecting frame 1 by the fixing grooves 11 and fixing blocks 12, and are inserted into the reinforcing limiting grooves 5 opened on the upper and lower sides of the rear end of the adjacent connecting frames 1, making the connection between the multiple connecting frames 1 more secure.
[0030] Preferably, the inner walls of the two reinforcing limiting grooves 5 near the connecting plug 2 are both connected to buffer grooves 6. A buffer slider 7 is engaged inside the buffer groove 6 and slidably connected within it. Two limiting heads 8 are provided at the end of the buffer slider 7 away from the buffer groove 6, and both limiting heads 8 protrude inside the reinforcing limiting groove 5. A limiting rod 9 passes through the buffer slider 7 from front to back, and the front and rear ends of the limiting rod 9 are fixedly connected to the inner walls of the front and rear ends of the buffer groove 6, respectively. An energy-absorbing spring 10 is provided inside the rear end of the buffer slider 7 and is sleeved on the outside of the limiting rod 9. The buffer slider 7 is elastically connected to the buffer groove 6 through the energy-absorbing spring 10. Two limiting grooves 14 pass through the upper front side of the deformation buffer plate 13, connecting the deformation buffer plate 13 to the two connecting plugs 2. When connecting the two adjacent connecting frames 1, the deformation buffer plate 13 is engaged with the limiting head 8 inside the reinforcing limiting groove 5 through the limiting slot 14. The limiting head 8 is elastically connected inside the buffer slide 6 through the buffer slider 7 and the energy-absorbing spring 10. When the two adjacent connecting frames 1 are subjected to external force and bend vertically, the external force on the connecting frame 1 is transmitted to the deformation buffer plate 13 through the fixing block 12, causing the deformation buffer plate 13 to slide inside the reinforcing limiting groove 5 and pull the buffer slider 7 and the limiting head 8 to slide together. At this time, the buffer slider 7 and the limiting head 8 can absorb the external force on the deformation buffer plate 13 through the deformation of the energy-absorbing spring 10, reducing the impact of the external force on the steel space frame. At the same time, the deformation buffer plate 13 can return to its original position in time under the action of the energy-absorbing spring 10, ensuring the structural stability of the steel space frame.
