Description

Technical Field

[0001] The present application relates to the technical field of steel structure buildings, and in particular to an earthquake-resistant steel structure building. Background Art

[0002] Steel structure is a building structure that uses steel as the main structural material. Steel has the characteristics of high strength, high rigidity, and good plasticity. Compared with traditional concrete structures, steel structures have better seismic performance and lighter weight. They can be prefabricated in factories and then quickly installed, with a short construction period. Steel structures can be used in various types of buildings, such as factories, warehouses, commercial buildings, bridges, etc. Conventional steel structures are mostly connected by bolts or welding during installation. Once the building is subjected to a large external force and vibrates, the interaction force between the components of the steel structure can easily cause deformation or cracking of the bolted connections or welds, which will affect the connection strength of the steel structure, reduce its seismic performance, and create safety hazards. Therefore, it is necessary to enhance the seismic resistance between the components of the steel structure to further improve the overall seismic performance of the steel structure.

[0003] For example, in the existing Chinese patent with the publication number CN114382177A, a seismic node of a steel structure for an assembled building is disclosed, which includes a steel column arranged vertically and a steel beam arranged horizontally. Two bearing plates distributed vertically are fixedly connected to the side wall of the steel column. Two elastic plates are fixedly connected to the opposite side walls of the two bearing plates. There is an angle between the two elastic plates on the same bearing plate, and the opening of the angle is arranged toward the other bearing plate. The end of the steel beam is located between the two bearing plates, and the top and bottom of the steel beam are provided with a supporting member. Through the above-mentioned prior art, when the steel structure vibrates, the steel beam can force the elastic plate to bend and deform through the supporting member to drive the fixed plate to move, so as to squeeze the filler in the cavity, thereby reducing the possibility of the steel beam and the steel column being separated when the node vibrates. When the steel structure stops vibrating, the deformation force of the elastic plate can push the steel beam to reset. The steel beam and the steel ball are flexibly connected through the above-mentioned bearing plate and the elastic plate, and the flexible connection improves the seismic performance of the connection node between the steel beam and the steel column.

[0004] However, the above prior art has the following technical defects:

[0005] In the above device, the two bearing plates that play the most important role in bearing the steel beam are welded on the steel column, and the two limit plates that directly and always contact the steel beam to keep it horizontal are bolted to the two bearing plates; when vibration occurs at the node, the steel beam forces the elastic plate to deform through the top support, thereby realizing the flexible connection between the steel column and the steel beam. However, since the two limit plates always contact and limit the steel beam, the force will be transmitted to the bearing plate welded on the steel column and the triangular brace bolted to the bearing plate and the steel column through the limit plates when vibration occurs, so that deformation or cracking is still easy to occur at the bolt connection and welding.

[0006] In the description of the above-mentioned prior art, it is explained that the reason why the installation method of the limit plate and the triangular brace is set to bolted is that when the triangular brace and the limit plate are deformed by vibration, workers can disassemble the triangular brace and the limit plate for replacement or repair. This means that the triangular brace and the limit plate are vulnerable parts, and the triangular brace and the limit plate are easily damaged when vibration occurs, resulting in poor stability of the connection between the above-mentioned device and the steel column when vibration occurs, and the steel beam is prone to detach from the steel column.

[0007] Based on this, on the basis of the existing seismic-resistant node of steel structure for prefabricated buildings, there is still room for improvement in order to overcome the above-mentioned technical defects. Summary of the invention

[0038] The following is combined with Figure 1-Figure 12 This application is described in further detail.

[0039] The embodiment of the present application discloses an earthquake-resistant building steel structure, which can disperse the interaction forces between the various connections of the steel structure when vibration occurs, improve the overall earthquake resistance of the steel structure, and ensure the stability of the connections between the various components of the steel structure. Example

[0040] Reference Figure 1 and Figure 2 As shown, the present application provides an earthquake-resistant building steel structure, including a main steel beam 1 and a cross beam 11 arranged on one side of the main steel beam 1, one end of the cross beam 11 has a card interface 111, and a docking device 2 is provided at the connection between the main steel beam 1 and the cross beam 11; the cross beam 11 can be quickly and firmly connected to the main steel beam 1 through the docking device 2, and at the same time, the connection point between the main steel beam 1 and the cross beam 11 can have a certain earthquake-resistant performance.

[0041] The docking device 2 includes a main assembly seat 22 connected to the main steel beam 1 by welding and two bottom bolts 21. In this embodiment, a sub-assembly seat 24 adapted to the main assembly seat 22 is preferably provided at the clamping interface 111 of the cross beam 11 through two pairs of middle bolts 23, and the sub-assembly seat 24 can be docked in the main assembly seat 22. A seismic connection mechanism 3 is provided in the main assembly seat 22 and the sub-assembly seat 24. Under the action of the seismic connection mechanism 3, the sub-assembly seat 24 can be firmly connected to the main assembly seat 22 while having certain seismic resistance, so as to achieve the purpose of improving the seismic resistance of the overall steel structure after the cross beam 11 is connected to the main steel beam 1.

[0042] The cross beam 11 in this embodiment is in a state of long-term use after being connected to the main steel beam 1, and does not need to be frequently disassembled and reassembled. Based on this premise, before the cross beam 11 needs to be connected and installed with the main steel beam 1, the auxiliary assembly seat 24 is first assembled and connected to the main assembly seat 22 through the anti-seismic connection mechanism 3, so that the two are first firmly connected, and then the main assembly seat 22 is installed on the main steel beam 1 by welding and bolting, and then the end of the cross beam 11 with the card interface 111 is installed on the auxiliary assembly seat 24 through two pairs of middle bolts 23, so that the staff can quickly install the cross beam 11 on the main steel beam 1.

[0043] Reference Figure 3 and Figure 4 As shown, specifically, the seismic connection mechanism 3 includes a rectangular bottom plate 31, a tightening assembly 4 and a connecting unit 5; the rectangular bottom plate 31 is installed on the lower side of the auxiliary assembly seat 24, and a plurality of conductive balls 32 are arranged in a matrix on the lower side of the rectangular bottom plate 31 for limited rotation. The tightening assembly 4 is arranged in the auxiliary assembly seat 24, so that the auxiliary assembly seat 24 can be tightly and firmly connected to the main assembly seat 22. The connecting unit 5 is arranged on the auxiliary assembly seat 24 and the main assembly seat 22, so as to further improve the connection effect between the auxiliary assembly seat 24 and the main assembly seat 22.

[0044] Under the joint action of the connecting unit 5 and the abutting assembly 4 , the connection between the auxiliary assembly seat 24 and the main assembly seat 22 can be made more stable, and at the same time have a certain anti-vibration performance.

[0045] Replay Figure 3As shown, in order to be able to limit the connection with the auxiliary assembly seat 24, a rectangular inner plate 33 matching with the conductive ball 32 is installed in the main assembly seat 22, and a matrix groove 331 matching with the conductive ball 32 is opened on the rectangular inner plate 33. The rectangular inner plate 33 is made of rubber. After the auxiliary assembly seat 24 is docked in the main assembly seat 22, the plurality of conductive balls 32 installed on the lower side of the auxiliary assembly seat 24 through the rectangular bottom plate 31 will be correspondingly clamped in the matrix groove 331 on the rectangular inner plate 33, and then cooperate with the operation of the tightening component 4 to enable the conductive ball 32 to be firmly pressed in the matrix groove 331. The rectangular inner plate 33 made of rubber can improve the effect of firm pressing on the one hand, and on the other hand, when the main steel beam 1 and the cross beam 11 vibrate and transmit to the main assembly seat 22 and the auxiliary assembly seat 24, the conductive balls 32 and the rectangular inner plate 33 pressed against each other can also disperse and eliminate part of the vibration, thereby achieving an anti-seismic effect.

[0046] Reference Figure 5 As shown, considering the need to fasten the auxiliary assembly seat 24 to the main assembly seat 22, the tightening assembly 4 includes a spring rod 41 and a convex push block 42; the two spring rods 41 are symmetrically arranged in the auxiliary assembly seat 24, and the auxiliary assembly seat 24 is symmetrically provided with inner circular hole grooves 241 for the installation of the two spring rods 41, and the convex push block 42 is installed at the telescopic ends of the two spring rods 41. It should be noted that the two spring rods 41 always have a driving force to push the convex push block 42 upward, and the driving force of the two spring rods 41 is relatively large. The auxiliary assembly seat 24 is provided with an embedded groove 242 that is connected to the inner circular hole groove 241 for the convex push block 42 to be embedded and installed. The upper side of the convex push block 42 is provided with a rough surface to increase friction.

[0047] Reference Figure 5 and Figure 6 As shown, the auxiliary assembly seat 24 is provided with a limiting plug rod 43 for locking and limiting the convex push block 42, and the auxiliary assembly seat 24 is provided with a round rod hole 243 that is connected to the embedded groove 242 for the limiting plug rod 43 to be inserted and installed, and the convex push block 42 is provided with a U-shaped groove 421 that matches the limiting plug rod 43. In the initial state, the limiting plug rod 43 is inserted into the round rod hole 243 and abuts against the U-shaped groove 421 on the convex push block 42, so as to achieve the effect of locking the position of the convex push block 42. At this time, even under the driving action of the spring rod 41, the convex push block 42 will not extend out of the embedded groove 242.

[0048] After the auxiliary assembly seat 24 is docked in the main assembly seat 22 and the auxiliary assembly seat 24 and the main assembly seat 22 are firmly connected through the connecting unit 5, the limiting plug rod 43 is pulled outward to release the lock of the convex block 42. At this time, under the pushing action of the two spring rods 41, the convex block 42 always contacts the main assembly seat 22, thereby prompting the conductive ball 32 to be firmly pressed in the matrix groove 331, so that the auxiliary assembly seat 24 is firmly connected to the main assembly seat 22.

[0049] Reference Figure 7 As shown, since the auxiliary assembly seat 24 needs to be firmly connected and installed on the main assembly seat 22 and also has anti-seismic performance, the connection unit 5 includes a connection bolt 51 and a locking assembly 6; the connection bolt 51 is symmetrically installed on the side of the auxiliary assembly seat 24 facing the main assembly seat 22, and a number of rubber gaskets 52 are equidistantly sleeved on the connection bolt 51, and the rubber gasket 52 can play a shock-absorbing effect. The main assembly seat 22 is symmetrically provided with a connection through hole 221 adapted to the rubber gasket 52 for the connection bolt 51 to extend into, and a rectangular groove 222 connected to the connection through hole 221. The locking assembly 6 is arranged at the rectangular groove 222 of the main assembly seat 22, and is used to lock the auxiliary assembly seat 24 firmly connected to the main assembly seat 22.

[0050] When docking the auxiliary assembly seat 24 in the main assembly seat 22, first extend the two connecting bolts 51 installed on the auxiliary assembly seat 24 together with the rubber gasket 52 into the connecting through hole 221. The outer diameter of the rubber gasket 52 is the same as the inner diameter of the connecting through hole 221. One end of the connecting bolt 51 extends into the rectangular groove 222, and part of the rubber gasket 52 is in the connecting through hole 221, conflicting with the inner wall of the connecting through hole 221.

[0051] Reference Figure 8 and 9 As shown, it is a schematic diagram of the structure of the locking assembly 6 in this embodiment, the locking assembly 6 includes a hexagonal wheel 61 and a docking piece 7; the hexagonal wheel 61 is symmetrically limited and rotatably arranged on the main assembly seat 22, and a limiting groove 223 connected to the rectangular groove 222 for the installation of two hexagonal wheels 61 is opened on the main assembly seat 22, and an end cover plate 62 for limiting the hexagonal wheel 61 is covered at the rectangular groove 222 and the limiting groove 223 of the main assembly seat 22, and the docking piece 7 is installed on the hexagonal wheel 61 in the rectangular groove 222, so as to achieve a stable connection of the connecting bolt 51.

[0052] The docking member 7 includes a limiting bar 71 symmetrically mounted on one end of the hexagonal wheel 61 and a hexagonal nut 72 abutting against the two limiting bars 71. The hexagonal nut 72 is connected to the hexagonal wheel 61 via a fixing spring 73. It should be noted that the limiting bar 71 is made of rubber and has a shock-absorbing effect. When the hexagonal wheel 61 is driven to rotate, the hexagonal nut 72 can be driven to rotate by limiting the position of the two limiting bars 71 on the hexagonal nut 72. The hexagonal nut 72 has a threaded inner hole that matches the connecting bolt 51. The fixing spring 73 has a high strength and is not easily deformed, so as to achieve the effect of firmly connecting the hexagonal nut 72 to the hexagonal wheel 61.

[0053] When the auxiliary assembly seat 24 is docked with the main assembly seat 22, and one end of the connecting bolt 51 enters the rectangular groove 222, the staff rotates the two hexagonal wheels 61 at the same time, prompting the fixing spring 73, the two limiting bars 71 and the hexagonal nut 72 clamped by the two limiting bars 71 to rotate, so that the hexagonal nut 72 is threadedly sleeved on the connecting bolt 51 to achieve the purpose of threaded connection. And because the fixing spring 73 is strong and not easy to deform, the auxiliary assembly seat 24 is firmly connected to the main assembly seat 22. Then the limiting plug 43 is pulled out, so that the convex abutment block 42 is pressed against the main assembly seat 22, prompting the conductive ball 32 to firmly press against the matrix groove 331 on the rectangular inner plate 33, so as to further enhance the connection effect between the auxiliary assembly seat 24 and the main assembly seat 22.

[0054] When vibration occurs, when the auxiliary assembly seat 24 drives the connecting bolt 51 to vibrate, the multiple rubber gaskets 52 can achieve a shock-absorbing effect during the connection; and the vibration of the main assembly seat 22 can achieve a shock-absorbing effect during the connection through the rubber gasket 52, the limiting bar 71 and the fixing spring 73. With the action of the rectangular inner plate 33 and the multiple conductive balls 32, the shock-absorbing effect of the auxiliary assembly seat 24 and the main assembly seat 22 can be further improved. Example

[0055] Reference Fig.10 and Fig.11 As shown, on the basis of the first embodiment, in order to facilitate the staff to quickly assemble and disassemble, and to meet the requirements of the steel structure construction that needs to be frequently disassembled and reassembled, a quick assembly unit 8 is provided on the main assembly seat 22, and the quick assembly unit 8 includes an assembly rod 81 that is limitedly slidably arranged at the rectangular groove 222 of the main assembly seat 22, and a T-shaped slide groove 224 that is connected to the rectangular groove 222 for the assembly rod 81 to be installed is provided on the main assembly seat 22, and a middle groove wheel 82 is symmetrically limited and rotated on the assembly rod 81, and a rotation groove 811 for the installation of the middle groove wheel 82 is symmetrically provided on the assembly rod 81, and a U-shaped block 83 is provided on the rotation groove 811 of the assembly rod 81 to limit the middle groove wheel 82. In this embodiment, the inner hexagonal wheel 61 is removed and replaced with the middle groove wheel 82, and the docking member 7 is installed on the middle groove wheel 82, and when the middle groove wheel 82 is rotated by the driving force, it can drive the fixing spring 73, the two limiting bars 71, and the hexagonal nut 72 clamped by the two limiting bars 71 to rotate.

[0056] This embodiment is suitable for short-term use when the cross beam 11 needs to be frequently disassembled and reassembled after being connected to the main steel beam 1. At this time, during installation, the main assembly seat 22 is first installed on the main steel beam 1 by welding and bolting, and the auxiliary assembly seat 24 is installed on the end of the cross beam 11 with the card interface 111 through two pairs of middle bolts 23. When the cross beam 11 and the main steel beam 1 need to be disassembled, the auxiliary assembly seat 24 can be quickly separated from the main assembly seat 22 directly through the quick assembly unit 8. After separation, the auxiliary assembly seat 24 and the main assembly seat 22 can continue to be assembled on the cross beam 11 and the main steel beam 1, and there is no need to disassemble the auxiliary assembly seat 24 and the main assembly seat 22, so as to facilitate the next time the cross beam 11 and the main steel beam 1 can be quickly connected.

[0057] Reference Fig.12 As shown, a circular groove gear 85 is symmetrically arranged on one side of the main assembly seat 22 through an elliptical rod 84 to limit rotation, a square rod 86 is installed at one end of the middle groove wheel 82, and the square rod 86 penetrates the circular groove gear 85, and a square hole 851 is opened on the circular groove gear 85 for the square rod 86 to penetrate. It should be noted that the square rod 86 is fixedly connected to the middle groove wheel 82, and when the square rod 86 is rotated by force, it can drive the middle groove wheel 82 to rotate synchronously. A threaded round rod 87 is also rotatably arranged in the rectangular groove 222 of the main assembly seat 22, and one end of the threaded round rod 87 is threaded through the assembly rod 81 to extend outward and is between the two circular groove gears 85, and an internal threaded hole 812 adapted to the threaded round rod 87 is opened on the assembly rod 81 through the threaded round rod 87, and the rotating threaded round rod 87 can drive the assembly rod 81 to slide in the T-shaped slide groove 224 on the main assembly seat 22 in a limited position in cooperation with the internal threaded hole 812 opened on the assembly rod 81. A knob gear 88 is installed at the protruding end of the threaded round rod 87 , and the knob gear 88 and the two circular groove gears 85 are meshed with each other.

[0058] In the initial state, the assembly rod 81 is set away from the connecting through hole 221; when the auxiliary assembly seat 24 is docked with the main assembly seat 22, after the connecting bolt 51 installed on the auxiliary assembly seat 24 enters the rectangular groove 222, the limiting plug rod 43 is first pulled out to release the restriction on the convex block 42, so that the convex block 42 is in contact with the main assembly seat 22, and the auxiliary assembly seat 24 and the main assembly seat 22 are tightly and firmly connected. Then, the end button gear 88 is rotated to drive the assembly rod 81 to slide toward the connecting bolt 51 through the rotation of the threaded round rod 87, and the end button gear 88 will also drive the two circular groove gears 85 to rotate while rotating, and then drive the square rod 86 to rotate through the square hole 851 on the circular groove gear 85, that is, drive the middle groove wheel 82 to rotate, so that the hexagonal nut 72 moves toward the connecting bolt 51 and rotates at the same time, so that it can be threaded on the connecting bolt 51, and the hexagonal nut 72 is threadedly connected with the connecting bolt 51; realize the stable connection between the auxiliary assembly seat 24 and the main assembly seat 22. Then, the cross beam 11 and the main steel beam 1 are quickly connected.

[0059] When the short-term use is completed and the cross beam 11 and the main steel beam 1 need to be disassembled, the rotating end button gear 88 drives the assembly rod 81 to reset, and at the same time the hexagonal nut 72 rotates to disengage from the connecting bolt 51, and the limiting plug rod 43 is reinserted to lock the convex block 42, and finally the cross beam 11 and the main steel beam 1 are directly separated to complete the quick disassembly.

[0060] The implementation principle of this embodiment is:

[0061] (1) Assembly and docking: Different installation methods are adjusted according to the actual use needs of the main steel beam 1 and the cross beam 11; when the cross beam 11 needs to be used for a long time after being connected to the main steel beam 1, the auxiliary assembly seat 24 is assembled and connected to the main assembly seat 22 through the seismic connection mechanism 3, so that the two are first in a state of stable connection, and then the main assembly seat 22 is installed on the main steel beam 1 by welding and bolting, and then the end of the cross beam 11 with the card interface 111 is installed on the auxiliary assembly seat 24 through two pairs of middle bolts 23.

[0062] After the cross beam 11 is connected to the main steel beam 1, it needs to be frequently disassembled and reassembled. When it is in short-term use, the main assembly seat 22 is first installed on the main steel beam 1 by welding and bolting, and the auxiliary assembly seat 24 is installed on the end of the cross beam 11 with a card interface 111 through two pairs of middle bolts 23. When the cross beam 11 and the main steel beam 1 need to be quickly assembled and disassembled, the auxiliary assembly seat 24 can be quickly separated from the main assembly seat 22 directly through the quick-install unit 8.

[0063] (2) Stable connection: When the docking piece 7 is installed on the hexagonal wheel 61, the auxiliary assembly seat 24 is first docked with the main assembly seat 22. After one end of the connecting bolt 51 enters the rectangular groove 222, the staff rotates the two hexagonal wheels 61 at the same time, prompting the hexagonal nut 72 to rotate and thread onto the connecting bolt 51. This achieves the effect of firmly connecting the auxiliary assembly seat 24 to the main assembly seat 22. Then, the limiting plug rod 43 is pulled out, so that the convex abutment block 42 is pressed against the main assembly seat 22, prompting the conductive ball 32 to firmly press against the matrix groove 331 on the rectangular inner plate 33, so as to further enhance the connection effect between the auxiliary assembly seat 24 and the main assembly seat 22.

[0064] When the docking piece 7 is installed on the middle groove wheel 82, the main assembly seat 22 is first installed on the main steel beam 1 by welding and bolt connection, and the auxiliary assembly seat 24 is installed on the end of the crossbeam 11 with the card interface 111 through two pairs of middle bolts 23. The auxiliary assembly seat 24 is docked with the main assembly seat 22. After the connecting bolt 51 enters the rectangular groove 222, the limiting plug rod 43 is first pulled out to release the restriction on the convex block 42, so that the auxiliary assembly seat 24 and the main assembly seat 22 are tightly and firmly connected. Then, the end button gear 88 is rotated to drive the assembly rod 81 to slide in the direction of the connecting bolt 51, driving the hexagonal nut 72 to move in the direction of the connecting bolt 51 and rotate at the same time, so that the hexagonal nut 72 is threadedly connected with the connecting bolt 51; a stable connection between the auxiliary assembly seat 24 and the main assembly seat 22 is achieved.

[0065] (3) Connection shock absorption: When vibration occurs, the connection unit 5 located in the main assembly seat 22 and the auxiliary assembly seat 24 can play a shock-resistant role; when the auxiliary assembly seat 24 drives the connecting bolt 51 to vibrate, a plurality of rubber gaskets 52 can play a shock-absorbing role during the connection; and the vibration of the main assembly seat 22 can play a shock-absorbing role during the connection through the rubber gasket 52, the limiting bar 71 and the fixing spring 73.

[0066] (4) Tightening and shockproof: With the operation of the tightening component 4, the conductive ball 32 can be firmly pressed in the matrix groove 331. The rectangular inner plate 33 made of rubber can improve the effect of firm pressing. On the other hand, when the main steel beam 1 and the cross beam 11 vibrate and transmit the vibration to the main assembly seat 22 and the auxiliary assembly seat 24, the conductive ball 32 and the rectangular inner plate 33 pressed against each other can also disperse and eliminate part of the vibration, thereby achieving a shockproof effect.

[0067] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
