Description

Technical Field

[0001] This utility model relates to the field of building steel structure technology, specifically to a combined splicing type spanning steel frame structure. Background Technology

[0002] In the construction field, especially in the construction of large-span spatial structures (such as factories, warehouses, and large stadiums), traditional steel frame structures have many shortcomings. On the one hand, the components of traditional steel frame structures are mostly integrally welded or complexly cast on-site, which makes the components large in size and heavy in weight. During transportation, they are greatly restricted by traffic conditions (such as road width and bridge load-bearing capacity), resulting in high transportation costs and difficulties. On the other hand, during on-site construction, due to the integral nature of the components, the assembly process is complex and requires continuous operation of large hoisting equipment. This not only results in a long construction period but also places high demands on the space and load-bearing capacity of the construction site. Furthermore, on-site welding and other operations are easily affected by external factors such as weather, making it difficult to accurately control the construction quality.

[0003] To overcome these problems, people have continuously explored more efficient and convenient steel frame structure forms. The concept of modular splicing structures emerged, the core of which is to break down large steel frames into multiple small, standardized components, which are then assembled on-site using methods such as plug-in, snap-fit, and bolt connections. This design greatly reduces transportation difficulties and costs, while making on-site construction more flexible, allowing for rapid assembly according to actual needs, shortening the construction cycle, and improving construction efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a combined splicing cross-gate steel frame structure that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a combined splicing type gate steel frame structure, including support legs, the interior of the support legs is hollow, a main load-bearing beam is inserted into the support legs, the main load-bearing beam is arranged in a V-shape; a first reinforcing rib is fixedly connected to the support legs, the first reinforcing rib has a mounting hole, and an auxiliary connecting frame is fixedly connected to the first reinforcing rib; fixing ribs are symmetrically fixedly connected to the main load-bearing beam, the fixing ribs have mounting holes, and a crossbeam is snapped onto the fixing ribs.

[0006] Furthermore, a second reinforcing rib is fixedly connected to the support leg, the second reinforcing rib has mounting holes, and a fixing bracket is fixedly connected to the second reinforcing rib.

[0007] Furthermore, an auxiliary connecting frame is fixedly connected to the fixed frame, and a secondary load-bearing beam is fixedly connected to the fixed frame.

[0008] Furthermore, a crossbeam is fixedly connected to the secondary load-bearing beam.

[0009] Furthermore, a limiting plate is fixedly connected to the main load-bearing beam, and the limiting plate corresponds to the supporting leg.

[0010] Furthermore, the second reinforcing rib on the support leg functions similarly to the first reinforcing rib, providing support for the fixing of the bracket through itself and the mounting holes, further strengthening the structural strength of the support leg and enabling it to better withstand forces from different directions. After the bracket is fixed to the second reinforcing rib, it is fixedly connected to the auxiliary connecting frame, enhancing the horizontal connection stability. On the other hand, the secondary load-bearing beam fixed on the bracket can cooperate with the main load-bearing beam to share the load above. Especially when the span is large, the secondary load-bearing beam can effectively reduce the span of the main load-bearing beam, reduce its deflection, and improve the overall load-bearing capacity of the structure. In addition, crossbeams are also fixedly connected to the secondary load-bearing beam, further improving the horizontal force structure, so that the entire steel frame structure can form a stable force network in both the horizontal and vertical directions.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. This utility model forms a complete and stable force-bearing system through the cooperation of support legs, main load-bearing beams, reinforcing ribs, auxiliary connecting frames, crossbeams, fixing frames, and secondary load-bearing beams. The main load-bearing beams are arranged in a V-shape, which can effectively distribute the load. Together with the crossbeams and secondary load-bearing beams, they can efficiently transfer and share the pressure from above, reduce stress concentration in the components, and improve the overall structure's load-bearing capacity in both vertical and horizontal directions.

[0012] 2. This utility model features a hollow support leg for inserting the main load-bearing beam, a fixing rib on the main load-bearing beam for engaging the crossbeam, and auxiliary connecting frames and fixing frames secured by mounting holes on the reinforcing ribs. This design eliminates the need for complex welding processes during on-site assembly, simplifies operation, reduces the technical requirements for construction personnel, decreases on-site workload, greatly improves construction efficiency, and shortens the construction cycle.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] Example: Refer to Figures 1-4 A modular, spliced ​​steel frame structure for a gate includes a support leg 1, which is hollow inside. A main load-bearing beam 2 is inserted into the support leg 1 and is arranged in a V-shape. A first reinforcing rib 11 is fixedly connected to the support leg 1. The first reinforcing rib 11 has mounting holes and an auxiliary connecting frame 3 is fixedly connected to the first reinforcing rib 11. Fixing ribs 22 are symmetrically fixedly connected to the main load-bearing beam 2. The fixing ribs 22 have mounting holes and a crossbeam 23 is snapped onto the fixing ribs 22.

[0018] A second reinforcing rib 12 is fixedly connected to the support leg 1. The second reinforcing rib 12 has an installation hole and a fixing bracket 4 is fixedly connected to the second reinforcing rib 12.

[0019] An auxiliary connecting frame 3 is fixedly connected to the fixed frame 4, and a secondary load-bearing beam 5 is fixedly connected to the fixed frame 4.

[0020] A crossbeam 23 is fixedly connected to the secondary load-bearing beam 5.

[0021] A limiting plate 21 is fixedly connected to the main load-bearing beam 2, and the limiting plate 21 corresponds to the support leg 1.

[0022] The second reinforcing rib 12 on the support leg 1 has a similar function to the first reinforcing rib 11. Through itself and the mounting hole, it provides support for the fixing of the fixing frame 4, further strengthening the structural strength of the support leg 1, so that the support leg 1 can better withstand forces from different directions. After the fixing frame 4 is fixed on the second reinforcing rib 12, it is fixedly connected to the auxiliary connecting frame 3, which strengthens the horizontal connection stability. On the other hand, the secondary load-bearing beam 5 fixed on the fixing frame 4 can cooperate with the main load-bearing beam 2 to share the load above. Especially when the span is large, the secondary load-bearing beam 5 can effectively reduce the span of the main load-bearing beam 2, reduce its deflection, and improve the overall load-bearing capacity of the structure. In addition, the secondary load-bearing beam 5 is also fixedly connected to the crossbeam 23, which further improves the horizontal force structure, so that the entire steel frame structure can form a stable force network in both the horizontal and vertical directions.

[0023] This utility model uses the support leg 1 as the basic support component of the entire structure. The hollow design reduces its own weight and provides space for the subsequent insertion and installation of the main load-bearing beam 2. The main load-bearing beam 2 is inserted into the support leg 1 in a figure-eight shape. This figure-eight layout can effectively distribute the load from above, so that when the main load-bearing beam 2 is under pressure, the force can be transmitted to the support leg 1 more evenly. By utilizing the deformation of the triangle stability principle, the structural load-bearing and anti-tilting capacity in the vertical direction is enhanced.

[0024] The first reinforcing rib 11, which is fixedly connected to the support leg 1, enhances the local strength of the support leg 1 through its own structure. On the other hand, the mounting holes on it facilitate the fixing of the auxiliary connecting frame 3. The auxiliary connecting frame 3 is fixed by means of the mounting holes on the first reinforcing rib 11, which can play a role in connecting and reinforcing the support leg 1 in the horizontal direction, further improving the overall stability of the structure and preventing the support leg 1 from shaking or shifting.

[0025] The symmetrically fixed reinforcing bars 22 on the main load-bearing beam 2 not only provide a structural foundation for the crossbeam 23 to be connected, but also the mounting holes opened on them make it easier to fix the crossbeam 23 more firmly by means of fasteners. After the crossbeam 23 is connected to the fixed reinforcing bars 22, it can work together with the main load-bearing beam 2 to jointly bear the load above, and at the same time form a more complete force system in the horizontal direction, enhance the rigidity of the structure on the horizontal plane, and reduce deformation.

[0026] The second reinforcing rib 12 on the support leg 1 has a similar function to the first reinforcing rib 11. Through itself and the mounting hole, it provides support for the fixing of the fixing frame 4, further strengthening the structural strength of the support leg 1, so that the support leg 1 can better withstand forces from different directions. After the fixing frame 4 is fixed on the second reinforcing rib 12, it is fixedly connected to the auxiliary connecting frame 3, which strengthens the horizontal connection stability. On the other hand, the secondary load-bearing beam 5 fixed on the fixing frame 4 can cooperate with the main load-bearing beam 2 to share the load above. Especially when the span is large, the secondary load-bearing beam 5 can effectively reduce the span of the main load-bearing beam 2, reduce its deflection, and improve the overall load-bearing capacity of the structure. In addition, the secondary load-bearing beam 5 is also fixedly connected to the crossbeam 23, which further improves the horizontal force structure, so that the entire steel frame structure can form a stable force network in both the horizontal and vertical directions.

[0027] The limiting plate 21 on the main load-bearing beam 2 corresponds to the support leg 1. When the main load-bearing beam 2 is inserted into the support leg 1, it plays a limiting role, ensuring that the main load-bearing beam 2 is installed in the right position, ensuring that the relative positions between the components are accurate, making the force transmission path more reasonable, and avoiding local stress concentration caused by misalignment, which would affect the overall stability and service life of the structure.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
