Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, specifically a steel structure seismic bracing. Background Technology

[0002] Steel structures possess excellent ductility, which can offset the energy dissipation of seismic waves. Steel is essentially an isotropic material with high tensile, compressive, and shear strength, and also exhibits excellent ductility. In particular, steel structures, due to their unique high ductility, mitigate seismic responses. During building construction, steel structures are required for earthquake resistance, enhancing the stability of assembly processes. This is a seismic support facility specifically designed for building electromechanical systems (such as pipes, air ducts, and cable trays). Its core function is to resist seismic forces, preventing electromechanical systems from falling, breaking, or collapsing during earthquakes, thereby reducing secondary disasters (such as fires, floods, electric shocks, and injuries from falling objects), ensuring the unobstructed flow of lifelines and the operation of critical facilities.

[0003] For example, the steel structure seismic bracing disclosed in the authorization announcement number CN208347035U includes a base and a mounting base. A sleeve is vertically arranged at the center of the upper end face of the base, and connecting plates are integrally formed at both ends of the base. The connecting plates are vertically arranged on the upper end face of the base, and first connecting rods are vertically arranged on the opposite surfaces of the two sets of connecting plates. A first spring is arranged between the second connecting rod and the first connecting rod. The column is clearance-fitted with the inner cavity of the sleeve, and a second spring is sleeved on the outer side of the column and the sleeve. While it achieves the effect of the load on the mounting base surface being compressed by the baffle on the periphery of the column, and the second spring buffering the axial vibration of the column and sleeve; when the object on the mounting base surface is tilted, the two sets of symmetrically placed first springs effectively buffer the vibration in the tilt direction generated by the load; the combination of these two aspects improves the stability of the device and the load on the mounting base surface, thereby increasing its service life. At the same time, this utility model also has the advantages of simple structure, convenient installation, and relatively low cost, making it suitable for widespread application. However, this does not solve the problem that existing seismic bracing systems are generally not conducive to convenient multi-level adjustment of support positions, making it difficult to support supports at different locations, conveniently dampen and buffer the forces generated by vibration, and conveniently adjust the angle of pipes, thus affecting the convenience of multi-level adjustment of seismic bracing systems and the efficiency of installation. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure seismic bracing system to solve the problems mentioned in the background art, such as the inconvenience of multi-level adjustment of the seismic bracing for support, the inconvenience of supporting the bracing at different positions, the inconvenience of conveniently damping and buffering the force generated by vibration, and the inconvenience of conveniently adjusting the angle of the pipe, which affect the convenience of multi-level adjustment and the efficiency of installation of the seismic bracing system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure seismic bracing system, comprising a track assembly and a first track. Two sets of first tracks are arranged on the outside of the track assembly. Each first track has a support plate on its outside, a gimbal plate on its outside, a first retaining ring on its outside, and a second retaining ring on the outside of each first retaining ring. Four sets of expansion bolts are installed at the top of the track assembly. Four sets of first support blocks are arranged inside the track assembly. Each first support block extends through the track assembly to its outside. First rolling wheels are movably mounted on the surface of each first support block, and the first rolling wheels are slidably connected to the track assembly. A connecting block is installed at the bottom of each first support block, and the connecting block is connected to the first track. First threaded blocks are installed on the sidewalls of each first support block, and first threaded blocks are movably mounted inside each first threaded block. The first threaded rod is threadedly connected to the first threaded block, and extends through the first threaded block to its outside. A first brake plate is installed at the top of each first threaded rod. A first nut is fitted onto the surface of each first threaded rod below the first threaded block. Two sets of second support blocks are provided inside each first track. The second support blocks extend through the first track to its outside. The second support blocks are movably connected to a support plate. A second rolling wheel is movably installed on the surface of each second support block. The second rolling wheel is slidably connected to the first track. A second threaded block is installed on the side wall of each second support block. A second threaded rod is movably installed inside each second threaded block. The second threaded rod extends through the second threaded block to its outside. A second brake plate is installed at the top of each second threaded rod. A second nut is fitted onto the surface of each second threaded rod below the second threaded block.

[0006] Preferably, four sets of first spring shock absorbers with equal spacing are installed at the bottom end of each support plate, and first shafts are symmetrically and movably installed on the bottom sidewalls of each support plate.

[0007] Preferably, the surface of the first axis is fitted with a second spring shock absorber, and the second axis is symmetrically and movably installed on the side wall of the gimbal plate. The side of the second spring shock absorber away from the first axis is movably connected to the second axis.

[0008] Preferably, each of the gimbal plates has a symmetrically mounted rotating shaft at its bottom end, and each rotating shaft has a worm gear fitted on its surface. Each of the gimbal plates has two sets of support seats on the side away from the rotating shaft at its bottom end, and a worm gear is fitted between the two sets of support seats.

[0009] Preferably, all the worms extend through the support base to its outside, and a handwheel is installed on one side of each worm, and each worm meshes with a worm wheel.

[0010] Preferably, each of the rotating shafts has a connecting seat installed at its bottom end, and each connecting seat is connected to a first retaining ring. Each of the first retaining rings has a support shaft movably installed on one side, and each of the first retaining rings is movably connected to a second retaining ring through the support shaft.

[0011] Preferably, a rotating shaft is movably mounted on the other side of each of the first retaining rings, and a third threaded rod is fitted onto the surface of each rotating shaft. A groove is provided on one side of each of the second retaining rings.

[0012] Preferably, each of the second retaining rings is provided with a washer on its outer side, and each of the washers is provided with a third nut on its outer side, and each of the third nuts is threadedly connected to the third threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the seismic bracing not only realizes convenient multi-level adjustment of the seismic bracing position for support, making it convenient to support the bracing at different positions, but also facilitates the shock absorption and buffering of the force generated by vibration, and facilitates the convenient adjustment of the pipe angle, thus improving the convenience of multi-level adjustment of the seismic bracing and the efficiency of installation. Manually pulling the first support block causes the first roller to move the first support block inside the track assembly. The first support block then moves the connecting block, the first track, the support plate, the gimbal plate, the first retaining ring, and the second retaining ring to the designated position. When longitudinal adjustment is required, manually pulling the second support block causes the second roller to move the second support block inside the first track. The second support block then moves the support plate, the gimbal plate, the first retaining ring, and the second retaining ring to the designated position. This enables convenient multi-level adjustment of the seismic bracing, facilitating support for bracing at different positions and improving the flexibility of multi-level adjustment of the seismic bracing. Rotating the second retaining ring, with the limiting support of the support shaft and the cooperation of the first retaining ring, clamps the pipe, bringing the second retaining ring into contact with the first retaining ring. Rotating the third threaded rod, with the movable support of the rotating shaft, moves the third threaded rod into the groove inside the second retaining ring, tightening the third nut to ensure tight contact between the second and first retaining rings, thus fixing the pipe. When encountering external wall vibration, the force on the external wall is transmitted through the expansion bolts, track assembly, first track, and support plate to the surface of the four sets of first spring shock absorbers. The first spring shock absorbers dampen and buffer the downward vertical vibration force, while the support plate... The force is transmitted through two sets of first shafts to two sets of second spring shock absorbers. The second spring shock absorbers dampen and buffer the vibration force in the tilt direction, ultimately buffering most of the force and reducing the vibration amplitude of the first and second retaining rings. Manually turning the handwheel drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the rotating shaft, connecting seat, first retaining ring, second retaining ring, and pipe to rotate, allowing the pipe to rotate to the required angle. This enables the seismic brace to conveniently dampen and buffer the force generated by vibration, facilitates easy adjustment of the pipe angle, and improves the effectiveness of the seismic brace in damping and buffering the force generated by vibration.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-11This utility model provides an embodiment of a steel structure seismic bracing system, comprising a track assembly 1 and a first track 2. Two sets of first tracks 2 are arranged on the outside of the track assembly 1. Each first track 2 has a support plate 3 on its outside, and a gimbal plate 4 on its outside. Each gimbal plate 4 has a first retaining ring 29 on its outside, and a second retaining ring 30 on its outside. Four sets of expansion bolts 5 are installed at the top of the track assembly 1. Four sets of first support blocks 6 are arranged inside the track assembly 1, each first support block 6 extending through the track assembly 1 to its outside. First rolling wheels 7 are movably installed on the surface of each first support block 6, and the first rolling wheels 7 are slidably connected to the track assembly 1. Connecting blocks 8 are installed at the bottom of each first support block 6, and the connecting blocks 8 are connected to the first track 2. First threaded blocks 9 are installed on the side walls of each first support block 6, and first threaded rods 11 are movably installed inside each first threaded block 9, and the first threaded rods 11 are connected to the first track 2.

The inside of the first track 2 is provided with two sets of second support blocks 13. The second support blocks 13 extend through the first track 2 to its outside. The second support blocks 13 are movably connected to the support plate 3. The surface of the second support blocks 13 is movably equipped with a second rolling wheel 14. The second rolling wheel 14 is slidably connected to the first track 2. The side wall of the second support blocks 13 is equipped with a second threaded block 15.

The top of the second threaded rod 17 is equipped with a second brake plate 16. The surface of the second threaded rod 17 below the second threaded block 15 is fitted with a second nut 18. When using steel structure seismic bracing, four sets of expansion bolts 5 are connected to the external wall. The expansion bolts 5 fix and limit the track assembly 1. When lateral adjustment is required, the first support block 6 is manually pulled. Under the sliding support of the first rolling wheel 7 and the track assembly 1, the first rolling wheel 7 drives the first support block 6 to move inside the track assembly 1. The first support block 6 drives the connecting block 8, the first track 2, the support plate 3, the gimbal plate 4, the first retaining ring 29, and the second retaining ring 30 to move to the designated position. The first threaded rods 11 are manually rotated. Under the threaded connection between the first threaded rods 11 and the first threaded block 9, the first threaded rods 11 drive the first brake plate 10 to move upward, so that the first brake plate 10 contacts the track assembly 1 for braking. After the first brake plate 10 contacts the track assembly 1, the first nuts 12 are manually rotated. Under the cooperation of the first threaded block 9 and the first nut 12, the first threaded rods 11 are fixed and limited. When longitudinal adjustment is required... When the second support block 13 is manually pulled, under the sliding support of the second rolling wheel 14 and the first track 2, the second rolling wheel 14 drives the second support block 13 to move inside the first track 2. The second support block 13 drives the support plate 3, the gimbal plate 4, the first retaining ring 29, and the second retaining ring 30 to move to the designated position. Then, the second threaded rod 17 is manually rotated. Under the threaded connection between the second threaded rod 17 and the second threaded block 15, the second threaded rod 17 drives the second brake plate 16 to move upward, so that the second brake plate 16 contacts the first track 2 and brakes. After the second brake plate 16 contacts the first track 2, the second nut 18 is manually rotated. Under the cooperation of the second threaded block 15 and the second nut 18, the second threaded rod 17 is fixed and limited. This realizes convenient multi-level adjustment of the seismic brace for support, which facilitates support for the brace at different positions and improves the flexibility of multi-level adjustment of the seismic brace for support. Four sets of first spring shock absorbers 19 with equal spacing are installed at the bottom of the support plate 3, and first shafts 20 are symmetrically and movably installed on the bottom side wall of the support plate 3. The surface of the first shaft 20 is fitted with a second spring shock absorber 21. The side wall of the gimbal plate 4 is symmetrically and movably mounted with a second shaft 22. The side of the second spring shock absorber 21 away from the first shaft 20 is movably connected to the second shaft 22. The bottom end of the gimbal plate 4 is symmetrically mounted with a rotating shaft 23. The surface of the rotating shaft 23 is fitted with a worm gear 24. The bottom end of the gimbal plate 4 away from the rotating shaft 23 is fitted with two sets of support seats 25, and a worm gear 26 is fitted between the two sets of support seats 25. The worm gears 26 all extend through the support base 25 to its outside. A handwheel 27 is installed on one side of each worm gear 26. Each worm gear 26 meshes with a worm wheel 24. A connecting seat 28 is installed at the bottom of each rotating shaft 23. The connecting seat 28 is connected to the first retaining ring 29. A support shaft 31 is movably installed on one side of each first retaining ring 29. Each first retaining ring 29 is movably connected to the second retaining ring 30 through the support shaft 31. On the other side of the first retaining ring 29, a rotating shaft 32 is movably installed. The surface of the rotating shaft 32 is fitted with a third threaded rod 35. On one side of the second retaining ring 30, a groove 36 is provided. On the outside of the second retaining ring 30, a washer 33 is provided. On the outside of the washer 33, a third nut 34 is provided. The third nut 34 is threadedly connected to the third threaded rod 35. Rotating the second retaining ring 30, under the limiting support of the support shaft 31 and with the cooperation of the first retaining ring 29, clamps the pipe, bringing the second retaining ring 30 into contact with the first retaining ring 29. Rotating the third threaded rod 35, under the movable support of the rotating shaft 32, moves the third threaded rod 35 into the groove 36 inside the second retaining ring 30. The washer 33 is placed on the surface of the third threaded rod 35. With the threaded connection between the third threaded rod 35 and the third nut 34, the third nut 34 is tightened, bringing the second retaining ring 30 into close contact with the first retaining ring 29, thus fixing the pipe. When encountering external wall vibration, the force on the external wall is transmitted through the expansion bolt 5, track group 1, first track 2, and support plate 3 to the surface of the four sets of first spring shock absorbers 19. The first spring shock absorbers 19 dampen and buffer the vertically downward vibration force. The support plate 3 transmits force to two sets of second spring shock absorbers 21 via two sets of first shafts 20. The second spring shock absorbers 21 dampen and buffer the vibration force in the tilt direction, ultimately buffering most of the force and reducing the vibration amplitude of the first retaining ring 29 and the second retaining ring 30. When a certain angle needs to be rotated, the handwheel 27 is manually turned. With the support of the support seat 25, the handwheel 27 drives the worm gear 26 to rotate. Under the meshing of the worm gear 26 and the worm wheel 24, the worm gear 26 drives the worm wheel 24 to rotate. The worm wheel 24 drives the rotating shaft 23, the connecting seat 28, the first retaining ring 29, the second retaining ring 30, and the pipe to rotate, so that the pipe rotates to the required angle. This realizes the convenient damping and buffering of the force generated by vibration by the seismic support, facilitates the convenient adjustment of the pipe angle, and improves the damping and buffering effect of the seismic support on the force generated by vibration.

[0018] Working principle: Manually pulling the first support block 6 causes the first rolling wheel 7 to move the first support block 6 inside the track assembly 1. The first support block 6 moves the connecting block 8, the first track 2, the support plate 3, the gimbal plate 4, the first retaining ring 29, and the second retaining ring 30 to the designated position. When longitudinal adjustment is required, manually pulling the second support block 13 causes the second rolling wheel 14 to move the second support block 13 inside the first track 2. The second support block 13 moves the support plate 3, the gimbal plate 4, the first retaining ring 29, and the second retaining ring 30 to the designated position. Rotating the second retaining ring 30, under the limiting support of the support shaft 31 and with the cooperation of the first retaining ring 29, clamps the pipe, causing the second retaining ring 30 to contact the first retaining ring 29. Rotating the third threaded rod 35, under the movable support of the rotating shaft 32, causes the third threaded rod 35 to move into the groove 36 inside the second retaining ring 30, tightening the third nut 34. This ensures that the second retaining ring 30 and the first retaining ring 29 are in close contact, securing the pipe. When the external wall vibrates, the force on the external wall is transmitted through the expansion bolt 5, track group 1, first track 2, and support plate 3 to the surface of the four sets of first spring shock absorbers 19. The first spring shock absorbers 19 dampen and buffer the force of vertical downward vibration. At the same time, the support plate 3 transmits the force to the two sets of second spring shock absorbers 21 through the two sets of first shafts 20. The second spring shock absorbers 21 dampen and buffer the force of inclined vibration, ultimately buffering most of the force and reducing the vibration amplitude of the first retaining ring 29 and the second retaining ring 30. The handwheel 27 is manually turned, which drives the worm gear 26 to rotate. The worm gear 26 drives the worm wheel 24 to rotate, which drives the rotating shaft 23, connecting seat 28, first retaining ring 29, second retaining ring 30, and pipe to rotate, so that the pipe rotates to the required angle, thus completing the use of the seismic support.
