Description

TECHNICAL FIELD

[0002] With the acceleration of industrialization, steel structure plants are widely used in the field of industrial buildings due to their advantages of fast construction speed, light structure, high space utilization rate, etc. In earthquake-prone areas, in order to improve the anti-seismic performance of steel structure plants, the anti-seismic design of joints becomes one of the keys to structural safety. Most steel structure joints use welding or traditional rigid connection methods. On the one hand, such connection methods are not conducive to assembly construction, reducing construction efficiency. On the other hand, under the action of seismic load, they have problems such as insufficient energy dissipation capacity, difficulty in controlling connection stiffness, poor structural ductility, etc., and are difficult to meet the anti-seismic requirements under high-intensity earthquakes. At the same time, some traditional structures lack adaptability to multi-directional displacement (such as vertical, horizontal, and torsional) of the joint, and are prone to joint failure under seismic action, leading to failure of the overall structure.

[0003] In traditional joint structures, springs and other buffer components are arranged in multiple directions to achieve the buffering and anti-seismic effect of the cross beam relative to the vertical beam in multiple directions such as vertical, horizontal, and torsional. However, the traditional joint with multi-directional buffering and anti-seismic effect independently sets the anti-seismic effect in different directions, and has a large size. For example, springs need to be arranged in the horizontal direction, increasing the size requirement of the joint in the horizontal direction, making the joint structure complex and not compact. Moreover, when the cross beam has vertical displacement, the cross beam will also tilt to a certain extent. Currently, the structure only has a buffering strategy for vertical displacement, and has no good buffering effect for the tilting action following the vertical action. SUMMARY

[0020] 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.

[0021] Example 1: 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.

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.

[0023] like Figure 3 , Figure 4 and Figure 5As shown, the shaft body 9 is provided with two shaft body baffles 18, and the cross beam connecting body 5 is arranged between the two shaft body baffles 18 by welding or other connection methods, so that the shaft body 9 is driven to move when the cross beam connecting body 5 moves in any direction; each shaft body baffle 18 is rotatably provided with a vertical buffering mechanism on the side away from the cross beam connecting body 5, the vertical buffering mechanism can realize vertical buffering, the shaft body baffle 18 is rotatably connected with the vertical buffering mechanism, and the rotation of the cross beam connecting body 5 in the horizontal direction can be realized; the vertical buffering mechanism is sleeved on the shaft body 9 and can move in the axial direction of the shaft body 9, two baffles 24 are arranged in the box body 4, and the sides of the two vertical buffering mechanisms away from the cross beam connecting body 5 are respectively in contact with the two baffles 24, and the two baffles 24 limit the two vertical buffering mechanisms between the baffles 24 and the shaft body baffles 18; the shaft body 9 is respectively connected with a torsion-resistant sleeve 20 at both ends, so as to realize torsion buffering in the horizontal direction, and the torsion-resistant sleeve 20 is located on the side of the baffle 24 away from the vertical buffering mechanism.

[0024] Through the vertical buffering mechanism, the torsion-resistant sleeve 20 and the rotation arrangement relationship between the shaft body baffle 18 and the vertical buffering mechanism, the multi-directional buffering and anti-seismic purposes of vertical, horizontal and torsion are realized, the vertical buffering mechanism, the torsion-resistant sleeve 20 and the like are arranged along the axial direction of the shaft body, the structure is simple and compact, the size requirement of the node in the horizontal direction is reduced, and the problem of excessive size of the node in the horizontal direction is avoided; if the size of the node in the horizontal direction is too large, the land occupation of the factory building will be increased, and the utilization rate of the factory building will be affected.

[0025] The shaft body baffle 18 is provided with an annular groove, and the annular groove is provided with a ball 10; correspondingly, the vertical buffering mechanism comprises a first spring support 1501, a second spring support 1502 and a plurality of springs 11 arranged between the first spring support 1501 and the second spring support 1502 along the circumferential direction of the shaft body 9, and optionally, one spring 11 is arranged at each of the four corner positions; the first spring support 1501 is provided with an annular groove, and the ball 10 is arranged between the annular groove of the shaft body baffle 18 and the annular groove of the first spring support 1501.

[0026] When the cross beam 2 rotates in the horizontal direction, the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to rotate around the first spring support 1501, so as to avoid affecting the first spring support 1501 and the like, and the arrangement of the ball 10 improves the rotation flexibility and maximally reduces the torsional force on the first spring support 1501 and the like.

[0027] When the cross beam 2 moves in the vertical direction, the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move up and down, so that the spring 11 is compressed or stretched at this time, and the buffering in the vertical direction is realized.

[0028] The second spring support 1502 is provided with elastic pads 12 between the inner wall of the box body 4, when the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move horizontally, the elastic pads 12 are pressed to realize the buffering in the horizontal direction; and when the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move vertically and to be inclined, the elastic pads 12 in one direction are pressed at this time to realize the buffering purpose when being inclined. Optionally, as shown in Figure 6 The four edges of the second spring support 1502 are provided with elastic pads 12 between the inner wall of the box body 4; the elastic pads 12 are trapezoidal elastic pads, the upper base end of the trapezoidal elastic pad is arranged on the second spring support 1502, there is a gap between the adjacent trapezoidal elastic pads to avoid the mutual interference when the trapezoidal elastic pads are pressed, and the lower base size of the trapezoidal elastic pad is large to ensure the contact area with the inner wall of the box body 4 to ensure the buffering and shock resistance effect.

[0029] As shown in Figure 3 The cross beam connecting body 18 is provided with a rubber pad 14 between the first spring support 1501; optionally, the rubber pad 14 is located outside the shaft body baffle 18. When the cross beam 2 moves vertically, the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move up and down, at this time the rubber pad 14 is compressed to realize the buffering in the vertical direction. And when the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move vertically and to be inclined, at this time the local position of the rubber pad 14 is pressed to realize the buffering purpose when being inclined.

[0030] The shaft body 9 is provided with a ring-shaped gasket 13 between the first spring support 1501, the ring-shaped gasket 13 is an elastic gasket; optionally, the first spring support 1501 is sleeved on the shaft body 9, the ring-shaped gasket 13 is arranged on the outer wall of the shaft body 9 by bonding or the like. When the cross beam 2 moves horizontally, the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move horizontally, at this time the ring-shaped gasket 13 is compressed to realize the buffering in the horizontal direction. And when the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move vertically and to be inclined, at this time one side of the ring-shaped gasket 13 realizes the buffering purpose when being inclined.

[0031] In summary, by setting the elastic pad 12 on the spring support, and the setting and cooperation of the ring-shaped washer 13 and the rubber gasket 14, when the vertical displacement occurs, the shaft body 9 is tilted to extrude the elastic pad 12, the ring-shaped washer 13 and the rubber gasket 14 in one direction, the elastic pad 12, the ring-shaped washer 13 and the rubber gasket 14 provide tilt buffering, so that the shaft body 9 tends to be vertical, and has a comprehensive buffering effect.

[0032] As shown in Figure 7 and Figure 8 The anti-torsion assembly 20 includes two symmetrically arranged fixers 23, damping springs 22 arranged in the fixers 23, and a rack 21 slidingly arranged on the fixers 23; the two ends of the rack 21 are connected with the damping springs 22 in the two fixers 23 respectively, and the end of the shaft body 9 is provided with a gear 19 which is engaged with the rack 21. Optionally, the fixer 23 is fixedly arranged on the inner wall of the box body 4 or the box body 4, a through hole is formed in the fixer 23 for slidingly sleeving the rack 22, the end of the rack 22 is fixedly connected with one end of the damping spring 22, and the other end of the damping spring 22 is connected with the inner wall of the fixer 23; the gear 19 is fixed on the end of the shaft body 9, or external teeth are directly arranged on the end of the shaft body 9 and engaged with the rack 22.

[0033] When the cross beam 2 moves in the horizontal direction, the cross beam 2 drives the cross beam connecting body 5 and the shaft body 9 to move in the horizontal direction, at this time, the damping spring 22 is compressed or stretched, and buffering in the horizontal direction is realized. The combination of the damping spring 22, the elastic pad 12 and the ring-shaped washer 13 further improves the buffering and shock resistance effect in the horizontal direction.

[0034] The node used in the embodiment has multi-direction energy dissipation capacity, is easy to assemble, and is suitable for the assembly type anti-seismic node structure of the steel structure factory building. One principle of the embodiment is that: The shaft body 9 is provided with shaft body baffles 18 symmetrically arranged on the two sides and a ball groove is pre-set outside the shaft body baffles 18, and gears 19 are arranged at the two ends of the shaft body 9. The shaft body 9 serves as a pivot: the beam can produce a certain range of rotation angle with the column; the vertical displacement of the beam (or the column) can be transmitted to the spring 11 through the shaft body 9.

[0035] The anti-torsion assembly 20 includes the fixer 23, the force transmission rack 21 and the damping spring 22, and plays a role in resisting torsion and resisting one-way horizontal displacement. The entire anti-torsion assembly 20 is fixed on the box body 4 through the fixer 23, the torque and the horizontal force are transmitted to the rack 21 through the gear 19, and then transmitted to the damping spring 22 through the rack 21, and the energy dissipation effect is realized through the contraction and stretching of the damping spring 22.

[0036] The gear 19 of the shaft body 9 and the toothed plate 21 are engaged, when the beam or column is twisted, the torque is transmitted to the damping spring through the shaft body 9, the damping spring is energy-dissipated, and the influence of the torsion on the structure is reduced. When the beam or column is vertically displaced, the influence of the displacement on the structure is reduced through the buffering effect of the joint action of the spring 11 and the rubber pad 14.

[0037] The multiple elastic pads 12 are distributed around the inner wall of the box body 4, when the beam or column is horizontally displaced, the elastic pads 12 will generate a tensile side and a compression side, and slowly reset under the action of the self elastic force, thereby reducing the influence of the horizontal displacement on the structure, and the horizontal displacement is transmitted to the anti-torsion assembly 20 through the intermediate shaft body, and the damping spring 22 in the anti-torsion assembly 20 plays a role, thereby further playing a role in limiting the horizontal displacement.

[0038] The embodiment connects the beam, column and the box body 4 provided with the multifunctional anti-seismic device, so that the horizontal, vertical and torsional displacement under the action of the earthquake is effectively buffered and energy-dissipated, and the overall anti-seismic performance and structural ductility of the joint are improved. The devices such as the self-resetting trapezoidal elastic pad, the spring assembly, the ball limiting mechanism and the anti-torsion assembly are integrated in the joint, which can respond sensitively and have strong recovery ability under the action of multidirectional displacement, and can effectively reduce the transmission of the earthquake force and the structural damage. Meanwhile, the joint adopts an assembly type design, has a simple structure, is convenient for standardized production and rapid installation on site, improves the construction efficiency, and ensures the reliability and safety of the joint connection, and is suitable for popularization and application of the large-span steel structure plant in the earthquake area.
