Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically a large-span steel frame support structure. Background Technology

[0002] Large-span steel frame support structures are an important type of building structure. They are mainly made of steel and, thanks to their superior mechanical properties, can span large spaces. Their flexible spatial design can meet diverse building needs and are widely used in stadiums, exhibition centers, transportation hubs, and industrial plants.

[0003] According to the search, patent document CN220301775U discloses a large-span steel frame support structure, including multiple support columns and welded rods. Inclined welded rods are fixed between the multiple support columns, and a support structure is set between the welded rods and the support columns. The support structure includes a center plate, a positive lead screw, a negative lead screw, a lead screw cylinder, a flange ring, a top support rod, an arc plate, an arc cover, a rolling block, and a support block. Positive and negative lead screws are fixed on both sides of the center plate, and the ends of the positive and negative lead screws are threaded with lead screw cylinders. One end of the lead screw cylinder is integrally formed with a flange ring. The lead screw cylinder is vertically supported on the support columns, increasing the lateral force-bearing capacity of the support columns and greatly increasing the lateral force-bearing capacity of the multiple support columns. The multiple support columns can meet the requirements of large spans and have the advantage of strong force-bearing capacity.

[0004] The aforementioned comparative documents also have the following shortcomings: The aforementioned support structure supports the two support columns outward through the arc-shaped plate and arc-shaped cover, but lacks tensile constraints on the support columns. When the structure faces horizontal loads, the support columns are prone to lateral displacement due to the lack of tensile constraints, which reduces the overall stability of the structure.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution:

[0023] A large-span steel frame support structure includes a steel frame 1, on which a pair of bidirectional threaded rods 2 are installed. Each bidirectional threaded rod 2 is threaded with a pair of nuts 3. A connecting block 4 is fixedly connected to the top of one nut 3, and a connecting block 5 is fixedly connected to the top of the other nut 3. A guide rod 6 is slidably connected to the connecting block 4. One end of the guide rod 6 is fixedly connected to the connecting block 4. A pair of connecting rods 7 are fixedly connected to the opposite sides of the pair of nuts 3. A fixing sleeve 8 is fixedly connected to one end of each connecting rod 7. A connecting component is provided on the fixing sleeve 8 to hold the guide rod 6. Rotating the bidirectional threaded rod 2 causes a pair of nuts 3 to move away from each other. The guide rod 6 moves with one nut 3 via the connecting block 1 4, and the connecting block 2 5 moves with the other nut 3. The guide rod 6 and the connecting block 2 5 are relatively displaced. The guide rod 6 can prevent the nuts 3 from rotating with the bidirectional threaded rod 2. The nuts 3 drive the fixing sleeve 1 8 to support the corresponding support rod on the steel frame 1 via a pair of connecting rods 7. The connecting assembly can surround the support column, which can enhance the stability of the support column, effectively disperse external forces, reduce the risk of tilting or damage caused by uneven force, and improve the safety of the overall structure.

[0024] The connecting assembly includes a pair of connecting blocks 3 9, both of which are fixedly connected to the fixed sleeve 1 8. A rotating block 10 is rotatably connected between the pair of connecting blocks 3 9. A fixed sleeve 2 11 is rotatably connected to the rotating block 10. A housing 12 is fixedly connected to the outer periphery of the fixed sleeve 2 11. A threaded rod 13 is threadedly connected to the housing 12. A knob 14 is coaxially fixedly connected to one end of the threaded rod 13, and a cone 15 is rotatably connected to the other end of the threaded rod 13. A pair of pins 16 are slidably connected to the housing 12. A spring 17 is sleeved on the outer periphery of each pin 16. A limit cone 18 is fixedly connected to the end of each pin 16 near the cone 15. A pair of connecting blocks 16 are fixedly connected to the outer periphery of the fixed sleeve 1 8. Block 4 19, a pair of connecting blocks 4 19 are provided with slots on the side of each other, the slots are adapted to the pins 16, the fixing sleeve 2 11 rotates between a pair of connecting blocks 3 9 on the fixing sleeve 1 8 by rotating block 10, so that the fixing sleeve 2 11 and the fixing sleeve 1 8 surround the corresponding support rod on the steel frame 1, the housing 12 is located between a pair of connecting blocks 4 19, the screw rod 13 is driven to rotate forward on the housing 12 by the knob 14, the screw rod 13 drives the cone 15 to move, separate the limiting cones 18 that are close together, so that a pair of pins 16 move away from each other, the pins 16 are inserted into the slots on the corresponding connecting blocks 4 19, so that the fixing sleeve 2 11 and the fixing sleeve 1 8 are connected together;

[0025] A rotating ring 20 is coaxially fixedly connected to the bidirectional threaded rod 2. The outer circumference of the rotating ring 20 has multiple anti-slip grooves. The bidirectional threaded rod 2 is rotated by moving the rotating ring 20.

[0026] A limit cap is fixedly connected to the end of the guide rod 6 away from the connecting block 4. The limit cap can prevent the guide rod 6 and the connecting block 5 from separating.

[0027] The working principle of this utility model is as follows:

[0028] By holding the guide rod 6 and rotating the double-threaded rod 2 through the rotating ring 20, the double-threaded rod 2 rotates, causing the pair of nuts 3 to move away from each other. The guide rod 6 moves together with one nut 3 through the connecting block 1 4, and the connecting block 2 5 moves together with the other nut 3. The guide rod 6 and the connecting block 2 5 are relatively displaced. The guide rod 6 can prevent the nut 3 from rotating with the double-threaded rod 2. The nut 3 drives the fixing sleeve 1 8 to support the corresponding support rod on the steel frame 1 through a pair of connecting rods 7, which greatly improves the construction efficiency. At the same time, the double-threaded rod 2, together with the nut 3 and the connecting rod 7, can provide reliable fastening force to ensure that the fixing sleeve 1 8 is firmly locked in the steel frame 1, enhancing the structural stability.

[0029] The second fixed sleeve 11 rotates between a pair of connecting blocks 3 9 on the first fixed sleeve 8 via the rotating block 10, so that the second fixed sleeve 11 and the first fixed sleeve 8 surround the corresponding support rod on the steel frame 1. The housing 12 is located between a pair of connecting blocks 4 19. The screw rod 13 is driven to rotate forward on the housing 12 by the knob 14. The screw rod 13 drives the cone 15 to move, separating the limit cones 18 that are close together, so that a pair of pins 16 move away from each other. The pins 16 are inserted into the slots on the corresponding connecting blocks 4 19, so that the second fixed sleeve 11 and the first fixed sleeve 8 are connected together. This can enhance the stability of the support column, effectively disperse external forces, reduce the risk of tilting or damage caused by uneven force, and improve the safety of the overall structure.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
