Description

Technical Field

Steel structure has the advantages of high strength, light weight, fast construction speed, reusability, large span capacity, etc. It can withstand large loads and external forces, can be prefabricated in the factory and assembled on site, greatly shortening the construction period. Steel beams, as the main body of steel structure buildings, play a decisive role in the overall strength of steel structure buildings.

[0004] The above-mentioned steel column and steel beam connector plays an anti-seismic and buffering role through multiple stacked rubber pads; however, the supporting capacity of the rubber pads is limited and the friction force is relatively large. After being squeezed by the steel beam, the multiple rubber pads are tightly fitted together. The friction force of the rubber pads makes the shear force that each rubber pad can generate very limited. When the steel structure building is subjected to a large shock, the rubber pads have a poor buffering capacity due to the small shear force, so that the steel beam still produces a large shake, resulting in poor overall anti-seismic capacity of the steel structure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A steel beam connector with an anti-seismic buffer structure comprises a plurality of columns, the tops of the plurality of columns are fixedly connected with a buffer component, and the bottoms of the plurality of columns are fixedly connected with an anti-seismic component;

[0037] By adopting the above technical solution, the lower pier seat 51 is fixedly connected to the foundation of the steel structure building. When the steel structure building is shaken by external influences, the lower pier seat 51 is affected first, and drives the multiple thin steel plates 54 and the multiple thin rubber plates 55 on the outside of the lead core 53 to perform lateral shear movement. The multiple thin steel plates 54 and the multiple thin rubber plates 55 are staggered. The thin steel plates 54 can increase the overall bearing capacity of the seismic resistant assembly 5 and prevent the seismic resistant assembly 5 from collapsing and being damaged due to the excessive weight of the steel structure building; in addition, the multiple thin steel plates 54 isolate the multiple thin rubber plates 55, which can reduce the friction of the thin rubber plates 55, so that the multiple thin steel plates 54 and the multiple thin rubber plates 55 can generate a larger shear force, thereby increasing the overall lateral deformation capacity of the seismic resistant assembly 5, thereby reducing the vibration of the column 3.

[0038] In this embodiment, the seismic assembly 5 comprises a lower pier seat 51, a lead core 53 is fixedly connected to the middle of the top of the lower pier seat 51; the top of the lead core 53 is fixedly connected to the middle of the bottom of the upper pier seat 52, and the lower pier seat 51, the upper pier seat 52 and the lead core 53 are arranged in concentric circles with each other, and the diameters of the lower pier seat 51 and the upper pier seat 52 are the same;

[0039] The outer side of the lead core 53 is evenly sleeved with a plurality of thin steel plates 54 and a plurality of thin rubber plates 55, and the plurality of thin steel plates 54 and the plurality of thin rubber plates 55 are staggeredly distributed; the plurality of thin steel plates 54 are closely fitted with the plurality of thin rubber plates 55 respectively; the plurality of thin steel plates 54 and the plurality of thin rubber plates 55 are circular and have a diameter smaller than that of the lower pier 51;

[0040] The column 3 comprises a column body 31, the bottom of which is fixedly connected to a bottom plate 32, and the bottom of the bottom plate 32 is fixedly connected to the middle of the top of the upper pier 52 by a plurality of bolts; the top of the column body 31 is fixedly connected to a top plate 33, and the top of the top plate 33 is fixedly connected to the middle of the bottom of the base 76; the upper and lower ends of the column body 31 are both provided with a plurality of reinforcing ribs 34;

[0041] The tops of the multiple connecting seats 71 are fixedly connected to the multiple main beams 1 respectively; the multiple main beams 1 are all arranged at an angle, and every two adjacent main beams 1 among the multiple main beams 1 are fixedly connected by a connecting piece 6; cross beams 2 are arranged between the multiple main beams 1, and the two ends of the multiple cross beams 2 are fixedly connected to the multiple main beams 1 by connecting pieces 4 respectively.

[0042] By adopting the above technical scheme, when the shaking of the steel structure exceeds the bearing range of the seismic component 5, the vibration force that the seismic component 5 cannot absorb will be transmitted to the column 3, and the column 3 will transmit the vibration force to the buffer component 7. After the buffer component 7 is vibrated, the sliding column 74 will move on the surface of the base 76 through the bottom pad 77 at its bottom. Because the top surface of the base 76 is provided with a groove, the sliding column 74 and the bottom pad 77 will be reset along the groove of the base 76 after being misaligned with the base 76; similarly, the sliding member 73 will be reset along the groove of the middle pad 78 after being misaligned on the top surface of the middle pad 78; the sliding column 74 and the sliding member 73 will absorb the vibration force received during the process of dislocation and reset, so that the main beam 1 and the cross beam 2 above the buffer component 7 will not produce large shaking, and the steel structure building will not collapse.

[0043] The working principle of the utility model is as follows: the lower pier seat 51 is fixedly connected to the foundation of the steel structure building. When the steel structure building is affected by the outside and shakes, the lower pier seat 51 is first affected and drives the multiple thin steel plates 54 and the multiple thin rubber plates 55 outside the lead core 53 to perform lateral shearing movement. The multiple thin steel plates 54 and the multiple thin rubber plates 55 are staggered. The thin steel plates 54 can increase the overall bearing capacity of the earthquake-resistant assembly 5 and prevent the earthquake-resistant assembly 5 from collapsing and being damaged due to the excessive weight of the steel structure building. In addition, the multiple thin steel plates 54 isolate the multiple thin rubber plates 55, which can reduce the friction of the thin rubber plates 55, so that the multiple thin steel plates 54 and the multiple thin rubber plates 55 can generate a larger shearing force, thereby increasing the overall lateral deformation capacity of the earthquake-resistant assembly 5, thereby reducing the vibration of the column 3.

[0044] When the shaking of the steel structure exceeds the bearing range of the seismic component 5, the vibration force that the seismic component 5 cannot absorb will be transmitted to the column 3, and the column 3 will transmit the vibration force to the buffer component 7. After the buffer component 7 is vibrated, the sliding column 74 will move on the surface of the base 76 through the bottom pad 77 at its bottom. Because the top surface of the base 76 is provided with a groove, the sliding column 74 and the bottom pad 77 will be reset along the groove of the base 76 after being misaligned with the base 76; similarly, the sliding member 73 will be reset along the groove of the middle pad 78 after being misaligned on the top surface of the middle pad 78; the sliding column 74 and the sliding member 73 will absorb the vibration force received during the dislocation and reset process, so that the main beam 1 and the cross beam 2 above the buffer component 7 will not produce large shaking, and the steel structure building will not collapse.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
