Description

Technical Field

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

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] In steel structure buildings, the structural stability of the building mainly depends on steel structure columns (i.e. columns) and steel structure beams (i.e. beams). The connection between the columns and beams is the stress concentration point. Therefore, in order to improve the stability of steel structure buildings, it is necessary to ensure the connection strength between the two.

[0004] Currently, columns and beams are usually fixedly connected by welding or welding reinforcement after splicing. However, when a steel structure is shaken by earthquakes, strong winds, etc., stress concentration at the connection between the column and the beam can easily reduce the strength of the connection, or even cause a risk of disconnection. The earthquake resistance and safety need to be improved. Utility Model Content

[0005] The present application provides an earthquake-resistant steel structure for a building, which can effectively improve the connection strength between columns and beams, and improve the earthquake resistance and safety of the building steel structure.

[0006] The present application provides a building earthquake-resistant steel structure, which adopts the following technical solution:

[0007] A building earthquake-resistant steel structure comprises a plurality of columns, a plurality of beams, a plurality of buffer components and a plurality of support components;

[0008] The column has a cavity inside, and the top of the column is provided with a plurality of plug-in ports for the crossbeam to be plugged in and matched with, and the plug-in ports are communicated with the cavity;

[0009] The buffer assembly includes an abutment member, which is located in the cavity. After the crossbeam is plugged and matched with the column, the abutment member abuts against the end surface of the crossbeam in the vertical direction.

[0010] The support assembly includes a support rod, the support rod is located below the cross beam, the two ends of the support rod are rotatably connected to the column and the cross beam respectively, and the rotation axes of the two ends of the support rod are parallel to each other and perpendicular to the length direction of the column and the length direction of the cross beam;

[0011] After the crossbeam is plugged into and matched with the column and abuts against the abutment piece, a clearance space is formed above and below the crossbeam in the plug-in interface.

[0012] By adopting the above technical scheme, the buffer assembly can improve the connection strength between the beam and the column through the abutment member, and the support assembly can improve the connection strength between the beam and the column through the support rod, thereby improving the earthquake resistance and safety of the building steel structure; when the building steel structure vibrates, the rotatably connected support rod and the yielding opening can provide the beam with the conditions for displacement in the vertical plane, so that the vibration can mainly affect the beam, and after affecting the displacement of the beam, the beam can transmit the vibration to the column, and the vibration in the vertical direction has a lower impact on the column, thereby further improving the connection strength of the connection position between the beam and the column, and further improving the earthquake resistance and safety of the building steel structure.

[0013] Optionally, the buffer assembly further includes a seat body, a plurality of springs and a plurality of dampers;

[0014] The seat body is fixedly arranged on the column and is located in the cavity on a side of the abutment member away from the plug interface; the abutment member is slidably connected to the seat body, and the sliding direction of the abutment member is parallel to the length direction of the column;

[0015] The two ends of the spring are respectively connected to the seat body and the abutment member, and the spring drives the abutment member to slide to a position where it can fit and abut against the horizontal beam;

[0016] The plurality of dampers correspond to the plurality of springs one by one, and the dampers are arranged inside the springs.

[0017] By adopting the above technical solution, the buffer assembly can buffer the vibration of the beam along the vertical plane through the cooperation of the spring and the damper, thereby reducing the impact of the vibration on the beam and further improving the seismic resistance of the building steel structure.

[0018] Optionally, the buffer assembly further includes a plurality of clips, wherein the clips are arranged on the abutment members, and a clip groove is provided on the clips, and after the crossbeam is plugged into and fitted with the column, one end of the crossbeam close to the column is clipped into and fitted with the clip groove.

[0019] By adopting the above technical solution, it is convenient to form a connection between the crossbeam and the abutment, so that the crossbeam can transmit the vibration to the abutment, so that the crossbeam can be affected by the buffering effect of the buffer component during the process of up and down displacement caused by the vibration, thereby further improving the effect of the buffer component in improving the seismic resistance of the building steel structure.

[0020] Optionally, two buffer components are disposed in the cavity, and the two buffer components are respectively located above and below the plug interface.

[0021] By adopting the above technical solution, the two buffer components have a buffering effect on the beam at the upper and lower sides of the beam at the same time, which can further reduce the impact of vibration on the beam, thereby further improving the seismic resistance of the building steel structure.

[0022] Optionally, the support assembly further includes a sliding member, which is slidably connected to the crossbeam; the sliding direction of the sliding member is parallel to the length direction of the crossbeam, and one end of the support rod away from the column is rotatably connected to the sliding member.

[0023] By adopting the above technical solution, the sliding part slidably connected to the beam further improves the freedom of displacement of the beam after being affected by vibration, which can further concentrate the impact of vibration on the building steel structure on the beam, making it easier for the buffer component to buffer the vibration of the beam.

[0024] Optionally, the support assembly further comprises a plurality of positioning members, the crossbeam is provided with a plurality of positioning grooves for threaded engagement with the positioning members, the sliding member is provided with a plurality of through holes for the positioning members to pass through, and the through holes are waist-shaped holes whose length direction is parallel to the sliding direction of the sliding member.

[0026] Optionally, it further comprises a plurality of limit members with elastic deformation capability, wherein the limit members are arranged on the cross beam, and the limit members are in contact with and abut against each other on both sides of the sliding direction of the sliding member.

[0027] By adopting the above technical solution, the limiter is used to limit the sliding of the sliding part. When the beam is displaced due to vibration and causes the sliding of the sliding part, the sliding part will squeeze the limiter and deform. The limiter suppresses the sliding of the sliding part under the trend of its own elastic deformation recovery, thereby also having a buffering effect on the vibration of the beam, and further improving the seismic resistance of the building steel structure.

[0028] Optionally, a sliding groove for the sliding member to slide is provided on the crossbeam, and the sliding member and the limiting member are both arranged in the sliding groove.

[0029] By adopting the above technical solution, the sliding member can be conveniently connected to the crossbeam through sliding, and the position limiting member can be conveniently installed and positioned on the crossbeam. In addition, when the sliding member squeezes the position limiting member, the position limiting member has stronger position stability.

[0030] Optionally, it also includes a plurality of elastic protection pads, which are arranged on the opening walls on both sides of the plug-in port along the vertical direction. After the crossbeam and the column are plugged in and matched, the protection pads contact and abut against the crossbeam.

[0031] By adopting the above technical solution, when the beam is displaced due to vibration, the protection pad can protect the beam and reduce the probability of collision damage between the beam and the column. At the same time, the elasticity of the protection pad can also buffer the vibration of the beam.

[0032] In summary, the present application includes at least one of the following beneficial effects:

[0033] 1. It can effectively improve the connection strength between the column and the beam, and improve the structural strength of the connection between the two, thereby improving the seismic resistance and safety of the building steel structure;

[0034] 2. It can concentrate the impact of vibration on the building steel structure on the beam, so that the beam will be displaced in the vertical plane after being vibrated, and then the displacement of the beam will be buffered and suppressed, thereby reducing the impact of vibration on the beam, and further improving the seismic resistance of the building steel structure;

[0035] 3. The influence of vibration on the crossbeam can be dispersed by means of sliding parts connected by sliding, supporting rods connected by rotation, elastic limiters and other components, thereby reducing the influence of vibration on the crossbeam. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-3 This application is described in further detail.

[0041] Reference Figure 1 and Figure 2 The present application embodiment discloses a building earthquake-resistant steel structure, including a plurality of columns 1, a plurality of beams 2, a plurality of buffer components 3 and a plurality of support components 4. In this embodiment, for the convenience of subsequent expression, only a part of the steel structure is introduced and illustrated, and the steel structure as a whole is composed of a plurality of the above-mentioned parts.

[0042] In this embodiment, a part of the preferred steel structure includes a column 1 , four beams 2 , two buffer components 3 and four support components 4 .

[0043] The column 1 is a hollow square column as a whole, and has a square column-shaped cavity 5 inside. The column 1 is fixedly installed on the ground in a vertical position in the length direction, and the cross section of the column 1 is a square frame.

[0044] The top of the column 1 is provided with four plug-in ports 11 for the cross beam 2 to be plugged in and matched therewith. The four plug-in ports 11 are respectively located on the four peripheral side end surfaces of the column 1 , and the plug-in ports 11 are communicated with the cavity 5 .

[0045] The two buffer components 3 are both installed in the cavity 5 , and the positions of the two buffer components 3 in the cavity 5 are respectively located on both sides of the position of the plug-in port 11 along the vertical direction.

[0046] The buffer assembly 3 includes a seat body 31 , an abutment member 32 , a plurality of springs 33 and a plurality of dampers 34 .

[0047] The seat body 31 is fixedly connected to the column 1 , the abutment member 32 is located on a side of the seat body 31 close to the plug port 11 , and the abutment member 32 is slidably connected to the seat body 31 along a direction parallel to the length direction of the column 1 .

[0048] The plurality of springs 33 correspond to the plurality of dampers 34 one by one, and the plurality of springs 33 are installed between the seat body 31 and the abutment member 32, and the corresponding dampers 34 are installed inside the springs 33. In this embodiment, the springs 33 are preferably compression springs, and the springs 33 and the dampers 34 together preferably constitute a shock absorber, and the abutment member 32 has a tendency to fit and abut against the cross beam 2 after plugging and installation under the action of the plurality of shock absorbers.

[0049] Furthermore, the spring 33 and the corresponding damper 34 preferably form a two-way shock absorber. At this time, the abutment member 32 still has a tendency to fit against the crossbeam 2 after plugging and installation under the action of several two-way shock absorbers, and when the abutment member 32 slides on the above basis, the two-way shock absorbers can suppress its sliding and tend to quickly reset it.

[0050] The cross beam 2 is also a hollow square column as a whole, and the interior of the cross beam 2 also has a square column-shaped cavity 5. The cross beam 2 is fixed to the top of the column 1 in a horizontal position in the length direction. During the installation of the cross beam 2, one end of the cross beam 2 in the length direction needs to be passed through the insertion port 11 to enter the cavity 5 of the column 1.

[0051] At this time, the top end face and the bottom end face of one end of the crossbeam 2 that penetrates into the interior of the column 1 are respectively fitted and abutted against the end faces of the abutment members 32 of the two buffer assemblies 3; at the same time, the two side end faces of the crossbeam 2 are fitted and abutted against the two side walls of the plug-in port 11, and there is a gap between the top and bottom of the crossbeam 2 and the wall of the plug-in port 11, that is, a clearance opening 12 is formed in the plug-in port 11 above and below the crossbeam 2.

[0052] Furthermore, the buffer assembly 3 further includes a plurality of clamping members 35. In this embodiment, the clamping member 35 is preferably a plate-like structure with an L-shaped track, and the buffer assembly 3 preferably includes four clamping members 35 in total.

[0053] The four clamping members 35 are all fixedly mounted on the abutting member 32 , and are located on a side of the abutting member 32 away from the seat body 31 , and the four clamping members 35 correspond to the four cross beams 2 one by one, respectively.

[0054] A snap-in groove 351 is formed between the snap-in piece 35 and the abutment piece 32 . When one end of the beam 2 is plugged into the column 1 , the end of the beam 2 will snap into the corresponding snap-in groove 351 , and the snap-in piece 35 will also snap into the cavity 5 of the beam 2 .

[0055] The clamping piece 35 can play a limiting role in the process of plugging the cross beam 2 and the column 1, which is convenient for construction personnel to determine the position state of the cross beam 2 and the column 1 after installation and positioning. At the same time, after the clamping piece 35 is clamped and matched with the corresponding cross beam 2, the two clamping pieces 35 on the upper and lower sides of the cross beam 2 will simultaneously connect the cross beam 2 with the two abutment pieces 32 on its upper and lower sides.

[0056] At this time, if the beam 2 is affected by vibration, under the size limitation of the plug-in port 11, the beam 2 will be displaced in the vertical plane along its length direction, and the two abutment members 32 located on the upper and lower sides of the beam 2 will slide accordingly, and a number of bidirectional shock absorbers composed of springs 33 and dampers 34 will suppress the displacement of the beam 2, thereby having a buffering effect on the vibration of the beam 2.

[0057] Furthermore, elastic protective pads 6 are fixedly mounted on the wall of the vertical side of the plug port 11 of the column 1. In this embodiment, the protective pads 6 are preferably made of rubber material.

[0058] When the crossbeam 2 and the column 1 are plugged together and installed, the upper and lower sides of the crossbeam 2 located in the plug-in port 11 will contact and abut against the two protection pads 6 respectively, that is, the two protection pads 6 will fill the two clearance openings 12 respectively.

[0059] At this time, if the beam 2 is displaced by vibration, the protective pad 6 can protect the beam 2, reducing the probability of the beam 2 being damaged by collision with the column 1 during displacement. At the same time, the protective pad 6 can inhibit the displacement of the beam 2, thereby reducing the impact of vibration on the beam 2.

[0060] The support assembly 4 is used to support the cross beam 2 to improve the connection stability between the cross beam 2 and the column 1, and the four support assemblies 4 correspond to the four cross beams 2 one by one.

[0061] Reference Figure 2 and Figure 3 The support assembly 4 provides triangular support for the cross beam 2 below the connection position between the cross beam 2 and the column 1 . The support assembly 4 includes a support rod 41 , a sliding member 42 and a plurality of positioning members 43 .

[0062] A sliding groove 21 adapted to the sliding member 42 is provided near the end of the beam 2 in the length direction. The length direction of the sliding groove 21 is parallel to the length direction of the beam 2 , and the sliding groove 21 is located at the bottom of the beam 2 after the beam 2 is installed.

[0063] The sliding member 42 is installed in the sliding groove 21 and is slidably connected to the cross beam 2 , and the sliding direction of the sliding member 42 is parallel to the length direction of the cross beam 2 .

[0064] One end of the support rod 41 is rotatably connected to the sliding member 42 , and the other end of the support rod 41 is rotatably connected to the column 1 near the plug port 11 . The rotation axes at both ends of the support rod 41 are horizontal and perpendicular to the sliding direction of the sliding member 42 .

[0065] The sliding member 42 is provided with a plurality of through holes 421 , which are matched with the positioning members 43 and correspond one to one with the plurality of through holes 421 .

[0066] The cross beam 2 is provided with a plurality of positioning grooves 22 on the bottom groove wall of the sliding groove 21, and the plurality of positioning grooves 22 correspond to a plurality of positioning members 43. In this embodiment, the supporting assembly 4 preferably includes four positioning members 43, and the positioning members 43 are preferably bolts.

[0067] A thread matching the positioning member 43 is provided on the peripheral groove wall of the positioning groove 22. After the positioning member 43 passes through the corresponding through hole 421 on the sliding member 42, it is threadedly matched with the corresponding positioning hole on the beam 2 to complete the installation. After the four positioning members 43 are installed, the connection strength between the sliding member 42 and the beam 2 will be improved.

[0068] Furthermore, it is preferred that the positioning hole is a waist-shaped hole whose length direction is parallel to the sliding direction of the sliding member 42, so as to further facilitate the displacement of the beam 2 due to vibration.

[0069] After the sliding member 42 is connected to the cross beam 2, a plurality of stoppers 7 with elastic deformation capability are installed in the sliding groove 21 on the cross beam 2. In this embodiment, the stoppers 7 are preferably made of rubber material, and preferably two stoppers 7 are installed on each cross beam 2, and the two stoppers 7 respectively fill the space of the sliding groove 21 on both sides of the sliding member 42, and the stoppers 7 are fixedly connected to the cross beam 2.

[0070] When the beam 2 is displaced due to vibration, the support rod 41 will rotate and the sliding member 42 will slide accordingly. At this time, the limit members 7 on both sides of the sliding member 42 will inhibit the sliding of the sliding member 42, thereby further reducing the impact of the vibration on the beam 2, and further improving the seismic resistance of the building steel structure.

[0071] The implementation principle of a building earthquake-resistant steel structure in the embodiment of the present application is:

[0072] When the building steel structure is affected by vibration, the vibration will be directed to act on the beam 2, causing the beam 2 to have a tendency to move;

[0073] At this time, the buffer assembly 3 will suppress the displacement of the beam 2 through the two-way shock absorber, and the limit member 7 will suppress the displacement of the beam 2 by suppressing the sliding of the sliding member 42 and the rotation of the support rod 41. At the same time, the protection pad 6 will directly suppress the displacement of the beam 2, thereby reducing the impact of vibration on the beam 2, and thus improving the seismic resistance of the building steel structure.

[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
