Description

Technical Field

[0001] The utility model relates to the technical field of support frames, in particular to a high-safety torsion-resistant steel structure support frame. Background Art

[0002] High-safety torsion-resistant steel structure support frames usually use high-strength and high-toughness steel materials and undergo strict processing and quality control to ensure their structural safety and stability. Their main features include high strength, high toughness, steel structure, torsion-resistant design and connectors. High-safety torsion-resistant steel structure support frames can be widely used in buildings, bridges, tunnels, subways and other fields, with high safety and stability.

[0003] The existing high-safety torsion-resistant steel structure support frame is achieved by installing a filling rod inside a support beam tube with multiple threaded holes, and fixing the filling rod on the outside of the support beam tube through multiple connecting parts. The threaded rods on the connecting parts penetrate the multiple threaded holes on the support beam tube, closely contact the filling rods and fix them. However, too many holes on the outside of the support beam tube not only destroy the continuity of the support beam tube and affect its structural strength, but also may cause stress concentration, reducing its stability and safety under complex working conditions. When the support frame is subjected to large torsional loads or complex loads, the middle area may become a weak link in the structure, affecting the overall torsion resistance, load bearing and bending resistance.

[0004] Therefore, it is necessary to provide a new high-safety torsion-resistant steel structure support frame to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-safety torsion-resistant steel structure support frame.

[0006] The high-safety torsion-resistant steel structure support frame provided by the utility model comprises:

[0007] A plurality of support beam tubes, each of which is provided with connecting pieces on both sides, and a plurality of filling rods are slidably connected in the support beam tubes;

[0008] Two sliding sleeves are slidably connected to the outer surfaces of two support beam tubes arranged in a vertical direction. A plurality of fixing bolts are penetrated through the two sliding sleeves, and the fixing bolts penetrate the support beam tubes and are movably connected to the filling rods. Connecting blocks are fixedly connected to the two sides of the two sliding sleeves respectively, and the two connecting blocks are alternately fixed with a connecting oblique frame 1 and a connecting oblique frame 2.

[0009] Furthermore, the connecting member includes two connecting cross bars and two connecting vertical bars, the two connecting cross bars are fixedly connected to the horizontal positions of two adjacent supporting beam tubes, and the two connecting vertical bars are fixedly connected to the vertical positions of two adjacent supporting beam tubes.

[0010] Furthermore, an annular groove is formed through one side of the sliding sleeve, a threaded hole 2 connected to the annular groove is formed on the outer surface of the sliding sleeve, and the outer wall of the supporting beam tube is slidably connected to the inner wall of the annular groove of the sliding sleeve.

[0011] Furthermore, a plurality of threaded holes 1 are provided at equal intervals in the circumferential direction at the center position of the outer side wall of the support beam tube, and the fixing bolts are threadedly connected to the threaded hole 2 and the inner wall of the threaded hole 1 in sequence.

[0012] Furthermore, a limiting groove is provided through the support beam tube, and the limiting groove is communicated with the threaded hole.

[0013] Furthermore, there are four filling rods, which are arranged in a cross shape and slidably connected to the inner wall of the limiting groove of the support beam tube. The outer wall of the filling rod is provided with a threaded hole three, and the fixing bolt can extend into the threaded hole three of the filling rod.

[0014] Furthermore, the cross section of the filling rod is triangular, and extrusion blocks are fixedly connected to both sides of the filling rod, and two adjacent extrusion blocks located in the limiting groove fit each other.

[0015] Compared with the related art, the high-safety torsion-resistant steel structure support frame provided by the utility model has the following beneficial effects:

[0016] 1. The high-safety torsion-resistant steel structure support frame has only one threaded hole in the middle, which is used to fix the connection between the filling rod and the support beam tube. This effectively reduces the weakening of the overall performance of the support beam tube due to too many holes, ensures the integrity and strength of the beam tube structure, and provides a solid guarantee for the stable operation of the support frame under various complex working conditions.

[0017] 2. The high-safety torsion-resistant steel structure support frame is equipped with a sliding sleeve on the outer side of the middle part of the supporting beam tube, which is designed to enhance the torsion resistance of the middle part of the beam tube and provide strong protection for the support frame to withstand complex working conditions. The two connecting blocks are staggered with the diagonal frame 1 and the connecting diagonal frame 2, so that these areas show superior resistance when facing tensile or compressive loads, which not only enhances the overall stiffness of the support frame, but also effectively disperses the force, ensuring that the support frame can remain stable under complex stress conditions, further improving the safety of the overall structure.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] In the specific implementation process, Figures 1 to 5 As shown, the high-safety torsion-resistant steel structure support frame includes:

[0026] A plurality of support beam tubes 1, with connecting pieces respectively arranged on both sides of the plurality of support beam tubes 1, and a plurality of filling rods 12 slidably connected in the support beam tubes 1;

[0027] Two sliding sleeves 6, the two sliding sleeves 6 are slidably connected to the outer surfaces of two support beam tubes 1 arranged in the vertical direction, a plurality of fixing bolts 8 are penetrated on the two sliding sleeves 6, and the fixing bolts 8 penetrate the support beam tube 1 and abut against the filling rod 12, the two sliding sleeves 6 are respectively fixedly connected with connecting blocks 9 on both sides, and the two connecting blocks 9 are staggeredly fixed with connecting oblique frames 10 and connecting oblique frames 2 11;

[0028] It should be understood from the above scheme that the staff installs the two sliding sleeves 6 in accordance with the construction process and standard in the prior art by slidingly connecting the two sliding sleeves 6 to the center position of the outer surface of the support beam tube 1, and the sliding sleeve 6 is firmly fixed by two connecting blocks 9, and the two connecting blocks 9 are staggeredly fixed with the connecting oblique frame 1 10 and the connecting oblique frame 2 11, and the gap between the connecting blocks 9 is divided into a plurality of triangular areas, and then the filling rod 12 is arranged inside the support beam tube 1, and the fixing bolt 8 is tightened to make it contact with the filling rod 12 and fix it;

[0029] Thus, by adopting the above arrangement, by filling the filling rod 12 in the supporting beam tube 1, an additional supporting structure is formed inside the supporting beam tube 1, thereby enhancing the torsional performance of the beam tube. When the support frame is subjected to a torsional load, the filling rod 12 can effectively disperse the stress and prevent the beam tube from being locally overloaded, thereby preventing the beam tube from being damaged due to overload, and significantly improving the safety and durability of the overall structure.

[0030] The support frame only has a threaded hole 5 in the middle, which is used to fix the connection between the filling rod 12 and the support beam tube 1, which preferably reduces the weakening of the overall performance of the support beam tube 1 due to too many holes, ensures the integrity and strength of the beam tube structure, and provides a solid guarantee for the stable operation of the support frame under various complex working conditions;

[0031] The sliding sleeve 6 provided on the outer side of the middle part of the support beam tube 1 is intended to strengthen the key area in a targeted manner. The sliding sleeve 6 enhances the torsion resistance of the middle part of the beam tube, providing a strong guarantee for the support frame to resist complex working conditions. The two connecting blocks 9 are staggeredly fixed with the diagonal frame 1 and the connecting diagonal frame 2 11, dividing the gap between the connecting blocks 9 into multiple triangular areas. The triangular structure has inherent stability, so that these areas show excellent resistance when facing tensile or compressive loads. These triangular areas not only enhance the overall stiffness of the support frame, but also effectively disperse the force, ensuring that the support frame can remain stable under complex stress conditions, further improving the safety of the overall structure;

[0032] Optionally, the number of filling rods 12 inside the support beam tube 1 can be added or reduced at will according to actual needs, thereby improving the adaptability of the support frame. Regardless of facing different load conditions, structural requirements or possible structural modifications in the future, users can easily adjust the number of filling rods 12 to meet specific torsion resistance, load bearing and bending resistance requirements. When installing or removing the filling rods 12, each filling rod 12 is fixed by a separate fixing bolt 8. This independent fixing method ensures that when adding or removing the filling rods 12, the filling rods 12 will not interfere with each other, which greatly simplifies the installation, disassembly and adjustment process, improves work efficiency, and ensures the stability and safety of the support frame structure.

[0033] The connecting member includes two connecting cross bars 3 and two connecting vertical bars 4 . The two connecting cross bars 3 are fixedly connected to the horizontal positions of two adjacent supporting beam tubes 1 , and the two connecting vertical bars 4 are fixedly connected to the vertical positions of two adjacent supporting beam tubes 1 .

[0034] like Figures 1 to 5As shown, an annular through groove 15 is formed through one side of the sliding sleeve 6, and a threaded hole 2 7 connected to the annular through groove 15 is formed on the outer surface of the sliding sleeve 6. The outer wall of the support beam tube 1 is slidably connected to the inner wall of the annular through groove 15 of the sliding sleeve 6. A plurality of threaded holes 15 are formed at equal intervals in the circumferential direction at the center position of the outer wall of the support beam tube 1. The fixing bolts 8 are threadedly connected to the threaded hole 2 7 and the inner wall of the threaded hole 15 in sequence. A limiting groove 2 is formed through the support beam tube 1, and the limiting groove 2 is connected to the threaded hole 15. There are four filling rods 12, which are arranged in a cross and are slidably connected to the inner wall of the limiting groove 2 of the support beam tube 1. A threaded hole 3 13 is formed on the outer wall of the filling rod 12, and the fixing bolt 8 can extend into the threaded hole 3 13 of the filling rod 12. The cross section of the filling rod 12 is triangular, and extrusion blocks 14 are fixedly connected to both sides of the filling rod 12, and two adjacent extrusion blocks 14 located in the limiting groove 2 fit each other.

[0035] It should be understood from the above scheme that when the above sliding sleeve 6 needs to be arranged on the outside of the support beam tube 1, the annular through groove 15 of the sliding sleeve 6 is first accurately aligned with the outside of the support beam tube 1 and pushed in, so that the sliding sleeve 6 can slide freely on the support beam tube 1 and be adjusted to the center position of the support beam tube 1. When installing the fixing bolt 8, it is first threadedly connected to the threaded hole 2 7 and the threaded hole 1 5 in sequence, and finally enters the threaded hole 3 13 of the filling rod 12. The limiting groove 2 plays a horizontal guiding role for the threaded hole 3 13 in this process, ensuring that the bolt can be accurately inserted, and the fixing bolt 8 vertically limits the threaded hole 3 13;

[0036] Thus, by adopting the above arrangement, the fixing bolts 8 fix the filling rods 12, ensuring that the filling rods 12 are firmly fixed inside the support beam tube 1, and ensuring the tightness and stability of the connection between the filling rods 12 and the support beam tube 1;

[0037] By filling adjacent filling rods 12, the extrusion blocks 14 on one side thereof will fit closely with the adjacent extrusion blocks 14. This fit not only provides an effective connection between the filling rods 12, but more importantly, the contact between the extrusion blocks 14 generates a mutual support force, further enhancing the overall stability of the filling structure inside the support beam tube 1, ensuring that when facing a torsional load, the filling rods 12 can work together to effectively disperse stress and improve the overall torsional resistance of the support frame;

[0038] Optionally, the sliding sleeve 6 can be pre-installed on the outside of the supporting beam tube 1, and after the connecting cross bar 3 and the connecting vertical bar 4 are installed, the connecting block 9 is fixed between the two sliding sleeves 6, so that the sizes of the connecting block 9, the connecting diagonal frame 1 10 and the connecting diagonal frame 2 11 can be adjusted according to actual conditions to improve applicability.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
