Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically a beam-column structure for a steel roof. Background Technology

[0002] Steel structures are building structures assembled by welding, bolting, and other methods. They are widely used in large-scale projects such as industrial plants, commercial buildings, and bridges. They have advantages such as high strength, light weight, fast construction speed, and good seismic performance. Beams and columns are the basic load-bearing components in steel structures. Beams are mainly responsible for horizontal loads and supporting the weight of the roof or floors, while columns bear vertical loads and transmit the pressure of the superstructure to the foundation, together building a solid structural system to ensure the stability and safety of the building.

[0003] In the prior art, a Chinese utility model patent (publication number: CN222796691U) discloses a beam-column structure for a steel structure factory building. This structure uses a tensioning mechanism to support the middle of the beams and columns, reducing deformation without occupying ground space and increasing the usable area of ​​the factory building. A central support column is supported by a main steel cable, which in turn supports the middle of the beams and columns, thus stabilizing the beams and columns and improving the practicality of the device. However, the use of steel cables for support has limited strength, and over long-term use, it is prone to fatigue deformation and loss of tension, affecting the overall stability and safety of the structure. Furthermore, when welding the connecting seat to the beams and columns, the beams and columns are suspended, which can easily lead to welding position misalignment, affecting the accuracy of the welding position and thus the quality of installation.

[0023] 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.

[0024] like Figures 1 to 5 As shown, this utility model provides a beam-column structure for a steel structure roof, which includes a first crossbeam 1. Both ends of the first crossbeam 1 are threadedly connected to a first connecting assembly by a first bolt 2, and both sides of the lower surface of the first crossbeam 1 are threadedly connected to a support assembly by a second bolt 3.

[0025] The support assembly includes a first fixing plate 4. The upper surface of the first fixing plate 4 is threadedly connected to one side of the lower surface of the first crossbeam 1 by a second bolt 3. A support plate 5 is fixedly connected to the lower surface of the first fixing plate 4, and a second fixing plate 6 is fixedly connected to the lower surface of the support plate 5. The first fixing plate 4 can support the first crossbeam 1, ensuring the stability of the first crossbeam 1 during installation and preventing the installation position from shifting, which would affect the installation quality. The support plate 5 can provide effective support for the first crossbeam 1 and reasonably distribute the stress points to the second crossbeam 8, thereby improving the load-bearing capacity and structural stability of the first crossbeam 1 and preventing deformation, thus ensuring the stability and safety of the entire structure.

[0026] The lower surface of the second fixed plate 6 is threadedly connected to the second crossbeam 8 by the third bolt 7. Both ends of the second crossbeam 8 are threadedly connected to the second connecting assembly by the fourth bolt 9. Both sides of the lower surface of the second crossbeam 8 are threadedly connected to the force-bearing assembly by the fifth bolt 10.

[0027] The load-bearing components include a first mounting plate 11, the upper surface of which is threaded to one side of the lower surface of the second crossbeam 8 via a fourth bolt 9. A first diagonal brace 12 is fixedly connected to the lower surface of the first mounting plate 11, and a second mounting plate 13 is fixedly connected to the lower surface of the first diagonal brace 12. A connecting plate 14 is fixedly connected to one side of the first diagonal brace 12, and a second diagonal brace 15 is fixedly connected to one side of the connecting plate 14. Load-bearing plates 16 are fixedly connected to both sides of the second diagonal brace 15. The two ends of the first diagonal brace 12 are connected to the second crossbeam 8 and the column 22 respectively via the first mounting plate 11 and the second mounting plate 13. At the same time, the load-bearing plates 16 are pushed to the included angle between the two, which can provide effective support for the second crossbeam 8 to enhance its structural load-bearing capacity and improve the stability and convenience of the second crossbeam 8 during installation.

[0028] The first connecting component includes a locking block 17. The inner side of the locking block 17 is threadedly connected to one end of the first crossbeam 1 by a first bolt 2. A plate 18 is fixedly connected to one side of the locking block 17, and a clamping plate 19 is fixedly connected to one side of the plate 18. The second connecting component has the same structure as the first connecting component. The locking block 17 is used to connect to the first crossbeam 1 or the second crossbeam 8. The plate 18 connects the locking block 17 and the clamping plate 19 to form a whole. Then, the clamping plate 19 is connected to the column 22 to improve the disassembly of the device and facilitate subsequent maintenance and replacement.

[0029] The inner side of the clamping plate 19 is threaded with a connecting lug 21 by a sixth bolt 20. A column 22 is fixedly connected to one side of the connecting lug 21. The connecting lug 21 facilitates the connection of the column 22 to the first crossbeam 1 or the second crossbeam 8.

[0030] The upper surface of the load-bearing plate 16 is flush with the lower surface of the second crossbeam 8, and one side of the load-bearing plate 16 is flush with one side of the column 22. The load-bearing plate 16 is located at the angle between the second crossbeam 8 and the column 22, which can support the second crossbeam 8, ensure its stability during installation, and improve its load-bearing strength.

[0031] The second mounting plate 13 is inverted L-shaped. One side of the second mounting plate 13 is threaded to one side of the column 22 by the seventh bolt 23. One end of the outer surface of each bolt is threaded with a fastening nut, which can be screwed into one end of each bolt to prevent the bolts from falling off by themselves.

[0032] There are multiple sets of support plates 5. The first crossbeam 1 and the second crossbeam 8 are arranged in parallel. Multiple sets of support plates 5 can provide multiple supports for the lower surface of the first crossbeam 1 to distribute the force and avoid deformation.

[0033] Working steps: First, use the seventh bolt 23 to connect the second mounting plate 13 to the column 22. Then, place the second crossbeam 8 on top of the first mounting plate 11 and connect it using the fifth bolt 10. Next, use the fourth bolt 9 to connect the locking block 17 of the second connecting assembly to one end of the second crossbeam 8. At this time, one side of the force plate 16 supports one side of the column 22, and its upper surface supports the lower surface of the clamping plate 19. Then, use the sixth bolt 20 to connect the corresponding clamping plate 19 to the corresponding connecting ear 21. Next, use the third bolt 7 to connect the second fixing plate 6 to the upper surface of the second crossbeam 8. Then, place the first crossbeam 1 on top of the first fixing plate 4 and connect it using the second bolt 3. Finally, similarly, use the first bolt 2 to connect the locking block 17 of the first connecting assembly to the first crossbeam 1, and then use the corresponding sixth bolt 20 to connect the clamping plate 19 to the corresponding connecting ear 21 to achieve the overall installation of the device, making the device stable and capable of bearing high stress.
