Description

Technical Field

[0001] This application relates to the technical field of seismic-resistant building equipment, and in particular to a seismic-resistant steel structure support. Background Technology

[0002] In construction engineering, steel structure supports are widely used to support pipes, cable trays, and other facilities, and their seismic performance directly affects the overall safety of the building. Traditional steel structure supports are mostly rigid connection structures, relying solely on their own strength to resist vibrations, lacking specialized buffer and shock absorption designs. When an earthquake occurs, the supports are prone to deformation or breakage due to severe vibrations, leading to damage to the supported pipes, cables, and other facilities, and triggering secondary disasters. Utility Model Content

[0003] To address the problems mentioned in the background art, this application provides a seismic-resistant steel structure support.

[0004] The seismic-resistant steel structure support provided in this application adopts the following technical solution:

[0005] An anti-seismic steel structure support includes a base, columns, two crossbeams, and an anti-seismic buffer assembly;

[0006] The base is a rectangular steel plate, and a chassis is fixedly installed on the upper surface of the base;

[0007] The column is vertically fixed at the center of the upper surface of the base, and a sliding sleeve is slidably fitted on the side wall of the column;

[0008] Two crossbeams are symmetrically arranged on the sliding sleeve. Two mounting grooves are opened on the side wall of the sliding sleeve. The opposite ends of the two crossbeams are respectively inserted into the two mounting grooves. Multiple fixing bolts for fixing the crossbeams to the sliding sleeve are threaded through the side wall of the sliding sleeve.

[0009] The seismic buffer assembly includes a main spring, two secondary springs, and two dampers. The main spring is sleeved on the column and its two ends are fixedly connected to the base and the sliding sleeve, respectively. The upper surface of the base is symmetrically fixedly connected with connecting seats, and the lower surfaces of the two crossbeams are fixedly connected with fixing seats. The corresponding connecting seats and fixing seats are hinged together by dampers. The dampers are inclined, and two connecting discs are fixedly sleeved on the side wall of the dampers. The secondary springs are sleeved on the dampers and their two ends are fixedly connected to the two connecting discs, respectively.

[0010] Preferably, mounting holes are provided at all four corners of the base.

[0011] Preferably, both the main spring and the auxiliary spring are helical compression springs.

[0012] Preferably, the damper is a hydraulic damper, and the angle between it and the horizontal plane is 30°-60°.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] Compared to existing technologies, this composite seismic-resistant structure, which combines a main spring with a damping-secondary spring, achieves synchronous vibration reduction in both vertical and horizontal directions. The main spring efficiently absorbs vertical vibration energy, while the damper, in conjunction with the secondary spring, rapidly attenuates horizontal vibration. Compared to traditional rigid supports or single-direction vibration-damping supports, this structure can cope with complex multi-directional loads during earthquakes, significantly reducing the risk of damage to facilities caused by vibration. At the same time, the overall structure is relatively simple and easy to use, improving the practicality of the device. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0019] This application discloses an anti-seismic steel structure support. (Refer to...) Figure 1-2 An anti-seismic steel structure support includes a base 1, a column 3, two crossbeams 8, and an anti-seismic buffer assembly;

[0020] The base 1 is a rectangular steel plate, and mounting holes 5 are provided at all four corners of the base 1. The base plate 2 is fixedly installed on the upper surface of the base 1.

[0021] The column 3 is vertically fixed at the center of the upper surface of the base 1, and a sliding sleeve 9 is slidably fitted on the side wall of the column 3;

[0022] Two crossbeams 8 are symmetrically arranged on the sliding sleeve 9. Two mounting grooves 14 are opened on the side wall of the sliding sleeve 9. The opposite ends of the two crossbeams 8 are respectively inserted into the two mounting grooves 14. Multiple fixing bolts 10 for fixing the crossbeams 8 to the sliding sleeve 9 are threaded through the side wall of the sliding sleeve 9.

[0023] The seismic buffer assembly includes a main spring 4, two auxiliary springs 12, and two dampers 13. The main spring 4 is sleeved on the column 3 and its two ends are fixedly connected to the base 2 and the sliding sleeve 9, respectively. The upper surface of the base 1 is symmetrically fixedly connected to the connecting seat 6, and the lower surface of the two crossbeams 8 is fixedly connected to the fixing seat 7. The corresponding connecting seat 6 and fixing seat 7 are hinged together by the damper 13. The damper 13 is inclined and two connecting discs 11 are fixedly sleeved on the side wall of the damper 13. The auxiliary springs 12 are sleeved on the damper 13 and their two ends are fixedly connected to the two connecting discs 11, respectively. The main spring 4 and the auxiliary springs 12 are both helical compression springs, and the damper 13 is a hydraulic damper with an angle of 30°-60° with the horizontal plane.

[0024] The implementation principle of an earthquake-resistant steel structure support according to an embodiment of this application is as follows: During installation, the support is first fixed to the building wall, floor slab, or ground structure using expansion bolts through the mounting holes 5 at the four corners of the base 1, ensuring that the base 1 is tightly fitted to the mounting surface, providing a stable foundation for the support. Based on the size of the facility to be supported and the installation requirements, the positions of the two crossbeams 8 on the sliding sleeve 9 are adjusted: one end of the crossbeam 8 is inserted into the mounting groove 14 of the sliding sleeve 9, and after determining the position, the fixing bolts 10 on the side wall of the sliding sleeve 9 are tightened to firmly connect the crossbeam 8 and the sliding sleeve 9, forming a stable lateral load-bearing structure. Then, pipes, cable trays, and other facilities can be fixed to the crossbeams 8. When an earthquake occurs and vertical vibrations occur, the weight of the facility and the vibration load are transmitted to the sliding sleeve 9 through the crossbeams 8. The sliding sleeve 9 slides up and down along the column 3, at which time the main spring 4 sleeved on the column 3 is compressed or stretched. The main spring 4, as the core vertical damping component, absorbs vertical vibration energy through its own elastic deformation. Simultaneously, the chassis 2 provides stable support to the bottom of the main spring 4, preventing structural failure due to excessive spring deformation and effectively reducing the impact of vertical vibration on the facility. When horizontal vibration occurs, the crossbeam 8 causes the sliding sleeve 9 to shift horizontally, at which point the tilted damper 13 begins to operate. The two ends of the damper 13 are hinged to the connecting seat 6 of the base 1 and the fixing seat 7 of the crossbeam 8, respectively. Horizontal vibration causes the piston rod of the damper 13 to extend and retract along the cylinder body; the damping effect of the internal hydraulic oil quickly attenuates the horizontal vibration energy. Simultaneously, the secondary spring 12 on the damper 13 deforms synchronously with the extension and retraction of the damper 13, further buffering the horizontal load through its own elasticity and reducing the horizontal swaying amplitude of the crossbeam 8 and the sliding sleeve 9. The connecting plate 11 ensures that the secondary spring 12 is always in the preset position of the damper 13, preventing spring displacement from affecting the damping effect. Throughout the vibration process, the main spring 4, the auxiliary spring 12, and the damper 13 work together to absorb and attenuate vibration energy from the vertical and horizontal directions, respectively. At the same time, the sliding sleeve 9 and the column 3 slide together to ensure that the support only produces displacement in the preset direction during vibration, avoiding irregular deformation, thereby providing comprehensive seismic protection for the supported facilities.

[0025] In this process, the composite seismic-resistant structure combining the main spring 4 and the damping-secondary spring 12 achieves synchronous vibration reduction in both vertical and horizontal directions: the main spring 4 efficiently absorbs vertical vibration energy, and the damper 13, in conjunction with the secondary spring 12, quickly attenuates horizontal vibration. Compared with traditional rigid supports or single-direction vibration-damping supports, it can cope with complex multi-directional loads during earthquakes, significantly reducing the risk of damage to facilities caused by vibration. At the same time, the overall structure is relatively simple and very convenient to use, improving the practicality of the device.
