Description

Technical Field

[0001] This invention belongs to the field of seismic technology, and particularly relates to a seismic-resistant joint, method, steel structure beam assembly, and steel structure factory building. Background Technology

[0002] With the acceleration of industrialization, steel structure workshops are widely used in industrial buildings due to their advantages such as fast construction speed, lightweight structure, and high space utilization. In earthquake-prone areas, the seismic design of joints has become one of the key factors for structural safety in order to improve the seismic performance of steel structure workshops. Most steel structure joints adopt welding or traditional rigid connection methods. These connection methods are not conducive to prefabricated construction, reducing construction efficiency. On the other hand, under seismic loads, they have problems such as insufficient energy dissipation capacity, difficulty in controlling connection stiffness, and poor structural ductility, making it difficult to meet the seismic requirements under high-intensity earthquakes. At the same time, some traditional structures lack adaptability to multi-directional displacement of joints (such as vertical, horizontal, and torsional), making them prone to joint failure under seismic loading, leading to the failure of the entire structure.

[0003] In traditional node structures, buffer components such as springs in multiple directions are used to achieve a buffering and seismic resistance effect of the crossbeam relative to the vertical beam in multiple directions, including vertical, horizontal, and torsional. However, traditional nodes with multi-directional buffering and seismic resistance are designed independently for the seismic resistance effect in different directions, resulting in larger dimensions. For example, springs are required in the horizontal direction, which increases the size requirements of the node in the horizontal direction, making the node structure complex and not compact. Furthermore, when the crossbeam undergoes vertical displacement, in addition to the overall upward movement, it will also tilt to a certain extent in the lateral direction. Currently, the structure only has a buffering strategy for vertical displacement, but it does not have a good buffering effect for the tilting movement that follows the vertical movement.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] Example 1:

[0040] like Figures 1-4 As shown, this embodiment provides a seismic joint for a steel structure factory building, including a box 4 with vertical beams connected to both ends, a shaft 9 set inside the box 4, and a horizontal beam connector 5 vertically set on the shaft 9; one end of the horizontal beam connector 5 extends to the outside of the box 4 through a pre-set hole on the side of the box 4.

[0041] Optionally, vertical beam connecting plates 6 are respectively provided at both ends of the box body 4, and the vertical beam connecting plates 6 are provided with pre-reserved bolt holes 17; the two ends of the box body 4 are respectively connected to the first vertical beam segment 1 and the second vertical beam segment 3 by bolts 8. A horizontal beam connecting plate 7 is provided at the end of the horizontal beam connecting body 5 away from the shaft body 9 (the end extending out of the box body 4), and the horizontal beam connecting plate 7 is provided with pre-reserved bolt holes 16; the horizontal beam connecting body 5 is connected to the horizontal beam 2 by bolts 8. The provision of the vertical beam connecting plates 6 and the horizontal beam connecting plates 7, and the bolt connection by means of bolt holes, realizes the prefabricated connection of the seismic nodes of the steel structure factory building, the first vertical beam segment 1 (first column), the second vertical beam segment 3 (second column), and the horizontal beam 2.

[0042] like Figure 3 , Figure 4 and Figure 5As shown, two shaft baffles 18 are provided on the shaft 9. The crossbeam connector 5 is connected between the two shaft baffles 18 by welding or other means. When the crossbeam connector 5 moves in any direction, it drives the shaft 9 to move. Each shaft baffle 18 has a vertical buffer mechanism rotatably provided on the side away from the crossbeam connector 5. The vertical buffer mechanism can realize vertical buffering. The rotatable connection between the shaft baffle 18 and the vertical buffer mechanism can realize the horizontal rotation requirement of the crossbeam connector 5. The vertical buffer mechanism is sleeved on the shaft 9 and can move upward along the shaft 9. Two baffles 24 are provided inside the housing 4. The side of the two vertical buffer mechanisms away from the crossbeam connector 5 respectively contacts the two baffles 24. The two baffles 24 respectively limit the two vertical buffer mechanisms between the baffles 24 and the shaft baffle 18. Anti-torsion kits 20 are connected to both ends of the shaft 9 to realize torsional buffering in the horizontal direction. The anti-torsion kits 20 are located on the side of the baffles 24 away from the vertical buffer mechanism.

[0043] By utilizing the vertical buffer mechanism, the anti-torsion kit 20, and the rotational arrangement of the shaft baffle 18 with the vertical buffer mechanism, multi-directional buffering and seismic resistance in the vertical, horizontal, and torsional directions are achieved. Furthermore, the vertical buffer mechanism and the anti-torsion kit 20 are arranged along the axial direction of the shaft, resulting in a simple and compact structure. This reduces the dimensional requirements of the nodes in the horizontal direction and avoids the problem of excessively large nodes in the horizontal direction. If the horizontal dimensions of the nodes are too large, it will increase the floor area of ​​the factory building and affect the utilization rate of the factory building.

[0044] The shaft baffle 18 has an annular groove, and a ball bearing 10 is disposed in the annular groove. Correspondingly, the vertical buffer mechanism includes a first spring support 1501, a second spring support 1502, and a plurality of springs 11 disposed circumferentially between the first spring support 1501 and the second spring support 1502 along the shaft 9. Optionally, a spring 11 is disposed at each of the four corners. The first spring support 1501 has an annular groove, and the ball bearing 10 is disposed between the annular groove of the shaft baffle 18 and the annular groove of the first spring support 1501.

[0045] When the crossbeam 2 rotates horizontally, the crossbeam 2 drives the crossbeam connecting body 5 and the shaft 9 to rotate around the first spring support 1501, avoiding the influence on the first spring support 1501, etc. The setting of the ball bearing 10 improves the rotation flexibility and minimizes the torsional force on the first spring support 1501, etc.

[0046] When the crossbeam 2 moves vertically, the crossbeam 2 drives the crossbeam connector 5 and the shaft 9 to move up and down. At this time, the spring 11 is compressed or stretched to achieve buffering in the vertical direction.

[0047] An elastic pad 12 is provided between the second spring support 1502 and the inner wall of the housing 4. When the crossbeam 2 drives the crossbeam connector 5 and the shaft 9 to move horizontally, the elastic pad 12 is compressed, achieving horizontal buffering. Furthermore, when the crossbeam 2 drives the crossbeam connector 5 and the shaft 9 to move vertically and tilt, the elastic pad 12 in one direction is compressed, achieving buffering during tilting. Optionally, such as... Figure 6 As shown, elastic pads 12 are provided at the four edges of the second spring support 1502 and between them and the inner wall of the housing 4. The elastic pads 12 are trapezoidal elastic pads. The upper bottom of the trapezoidal elastic pads is set on the second spring support 1502. There is a certain gap between adjacent trapezoidal elastic pads to avoid mutual interference when the trapezoidal elastic pads are squeezed. The lower bottom of the trapezoidal elastic pads is large enough to have a large contact area with the inner wall of the housing 4, ensuring a buffering and shock-absorbing effect.

[0048] like Figure 3 As shown, a rubber gasket 14 is provided between the crossbeam connector 18 and the first spring support 1501; optionally, the rubber gasket 14 is located outside the shaft baffle 18. When the crossbeam 2 moves vertically, the crossbeam 2 drives the crossbeam connector 5 and the shaft 9 to move up and down, compressing the rubber gasket 14 to achieve vertical buffering. Furthermore, when the crossbeam 2 drives the crossbeam connector 5 and the shaft 9 to move vertically and tilt, the rubber gasket 14 is compressed at a local position to achieve buffering during tilting.

[0049] An annular washer 13, which is an elastic washer, is provided between the shaft 9 and the first spring support 1501. Optionally, the first spring support 1501 is sleeved on the shaft 9, and the annular washer 13 is provided on the outer wall of the shaft 9 by means of bonding or other methods. When the crossbeam 2 moves horizontally, the crossbeam 2 drives the crossbeam connecting body 5 and the shaft 9 to move horizontally, compressing the annular washer 13 to achieve horizontal buffering. Furthermore, when the crossbeam 2 drives the crossbeam connecting body 5 and the shaft 9 to move vertically and tilts, one side of the annular washer 13 provides buffering during tilting.

[0050] In summary, by setting and cooperating the elastic pad 12, annular washer 13, and rubber pad 14 on the spring support, when the vertical displacement occurs, the shaft 9 tilts and presses the elastic pad 12, annular washer 13, and rubber pad 14 in one direction. The elastic pad 12, annular washer 13, and rubber pad 14 provide tilt buffering, making the shaft 9 tend to be vertical, thus providing a comprehensive buffering effect.

[0051] like Figure 7 and Figure 8 As shown, the anti-torsion kit 20 includes two symmetrically arranged retainers 23, a damping spring 22 disposed within the retainer 23, and a rack 21 slidably disposed on the retainer 23. Both ends of the rack 21 are connected to the damping springs 22 within the two retainers 23, respectively. A gear 19 is provided at the end of the shaft 9, and the gear 19 meshes with the rack 21. Optionally, the retainer 23 is fixedly disposed on the inner wall of the 24 or the housing 4. The retainer 23 has a through hole for sliding engagement of the rack 22. One end of the rack 22 is fixedly connected to one end of the damping spring 22, and the other end of the damping spring 22 is connected to the inner wall of the retainer 23. The gear 19 is fixed to the end of the shaft 9, or external teeth are directly provided at the end of the shaft 9 to mesh with the rack 22.

[0052] When the crossbeam 2 moves horizontally, it drives the crossbeam connector 5 and the shaft 9 to move horizontally as well. At this time, the damping spring 22 is compressed or stretched to achieve horizontal buffering. The combined use of the damping spring 22, the elastic pad 12, and the annular washer 13 further improves the horizontal buffering and shock absorption effect.

[0053] The nodes used in this embodiment possess multi-directional energy dissipation capabilities, are easy to assemble, and are suitable for prefabricated seismic-resistant node structures in steel structure workshops. One of the principles of this embodiment is:

[0054] The shaft 9 is symmetrically provided with shaft baffles 18 on both sides, and ball grooves are preset on the outer side of the shaft baffles 18. Gears 19 are provided at both ends of the shaft 9. The shaft 9 acts as a pivot: it allows the beam and the column to rotate within a certain range; the vertical displacement generated by the beam (or column) can be transmitted to the spring 11 through the shaft 9.

[0055] The anti-torsion kit 20 includes a retainer 23, a force-transmitting rack 21, and a damping spring 22, serving to resist torsion and resist unidirectional horizontal displacement. The entire anti-torsion kit 20 is fixed to the housing 4 by the retainer 23. Torque and horizontal force are transmitted to the rack 21 through the gear 19, and then from the rack 21 to the damping spring 22. The contraction and extension of the damping spring 22 dissipate energy.

[0056] The gear 19 and toothed plate 21 of shaft 9 mesh. When the beam or column is torsional, the torque is transmitted to the damping spring through shaft 9. The damping spring dissipates the energy and reduces the impact of torsion on the structure. When the beam or column undergoes vertical displacement, the combined action of spring 11 and rubber pad 14 reduces the impact of displacement on the structure.

[0057] Multiple elastic pads 12 are distributed around the inner wall of the box 4. When the beam or column is horizontally displaced, the elastic pads 12 will generate tension and compression sides and slowly reset under their own elastic force, reducing the impact of horizontal displacement on the structure. At the same time, the horizontal displacement is transmitted to the anti-torsion kit 20 through the intermediate shaft. The damping spring 22 in the anti-torsion kit 20 plays a role in further limiting the horizontal displacement.

[0058] This embodiment connects beams and columns to a box 4 equipped with a multi-functional seismic-resistant device, effectively buffering and dissipating horizontal, vertical, and torsional displacements under seismic loads, thus improving the overall seismic performance and structural ductility of the joint. The joint integrates self-resetting trapezoidal elastic pads, spring assemblies, ball bearing limiting mechanisms, and anti-torsion components, enabling it to respond sensitively and recover strongly under multi-directional displacement, effectively reducing seismic force transmission and structural damage. Furthermore, the joint adopts a prefabricated design with a simple construction form, facilitating standardized production and rapid on-site installation. This improves construction efficiency while ensuring the reliability and safety of the joint connection, making it suitable for widespread application in large-span steel structure workshops in seismic zones.
