Description

Technical Field

[0001] This utility model relates to the field of seismic structure technology, and more specifically to a damped buckling composite high-efficiency seismic support structure. Background Technology

[0002] To improve seismic resistance, dampers and buckling-restrained braces are generally used in combination to enhance the safety of buildings during earthquakes and reduce the damage caused by earthquakes. The existing seismic-resistant structure, as shown in application number CN202220854783.X, composite buckling-restrained braced structure, is composed of a combination of bracing components and viscoelastic dampers. The viscoelastic damper is described as having a high-damping block firmly fixed to the blocking member and the cross core plate. When the cross core plate is subjected to seismic movement, the high-damping block can provide energy dissipation and vibration reduction. However, in this composite buckling-restrained brace structure, the high-damping blocks are directly connected and fixed at the inner and outer sides of the high-damping blocks. This is relatively perpendicular to the direction of the force on the cross core plate. When the high-damping blocks are deformed under force, the suppression range is large, and when the vibration amplitude is large, there is a disadvantage of insufficient damping effect. Utility Model Content

[0003] The purpose of this utility model is to provide a damped buckling composite high-efficiency seismic support structure in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a damped buckling composite high-efficiency seismic bracing structure, including a bracing component and a core rod provided thereon; It also includes a sleeve with a through-hole at the right end of the sleeve. A portion of the core rod extends into the sleeve through the through-hole. A pressure ring surrounds the outside of the core rod and is located inside the sleeve. A first washer and a second washer are fixed inside the sleeve. The pressure ring is located between the first washer ring and the second washer ring. The first washer ring and the second washer ring are surrounded outside the core rod with a gap. A first damping ring and a second damping ring are respectively provided between the pressure ring and the first washer ring and the second washer ring. The first damping ring and the second damping ring are sleeved outside the core rod. The second damping ring contacts the pressure ring and the second washer ring, the first damping ring contacts the pressure ring and the first washer ring, the left end of the core rod does not contact the left end of the inner wall of the casing, there is a deformation gap between the outer periphery of the first damping ring and the inner wall of the casing, and there is a deformation gap between the outer periphery of the second damping ring and the inner wall of the casing.

[0005] As a preferred embodiment of this utility model, there is a second gap between the second washer ring and the left end of the inner wall of the sleeve for the core rod to move.

[0006] As a preferred technical solution of this utility model, a limiting ring is fixed around the outside of the core rod. The limiting ring is inside the sleeve, the pressure ring is to the left of the limiting ring, and the limiting ring is between the first washer ring and the right end of the sleeve. The limiting ring does not contact the first washer ring, and the limiting ring does not contact the right end of the inner wall of the sleeve.

[0007] As a preferred technical solution of this utility model, there is a first gap between the first gasket and the right end of the inner wall of the sleeve for the movement of the limiting ring, and the limiting ring moves to fit the first gasket and the right end of the inner wall of the sleeve.

[0008] As a preferred embodiment of this utility model, the first damping ring and the second damping ring are made of butyl rubber or chloroprene rubber.

[0009] The beneficial effects of this utility model are as follows: When the core rod is displaced, the pressure ring quickly applies pressure to the first or second damping ring to ensure that the same energy dissipation effect is achieved whether it moves to the left or right, thus improving the damping effect during left and right swings. At the same time, the pressure on the first and second damping rings is left and right pressure, which ensures that the amount of compressive deformation provided by the first and second damping rings is large, so as to effectively dissipate energy for larger vibration amplitudes and improve the damping effect. When the core rod continues to move to the right, the limiting ring will contact the right end of the inner wall of the sleeve, and when the core rod continues to move to the left, the limiting ring will contact the first washer ring, thereby limiting the excessive swing of the core rod to the left and right. The displacement length is set while ensuring the effective deformation of the first damping ring or the second damping ring, so as to protect the service life of the first damping ring or the second damping ring. The outer ring ends of the first and second damping rings do not contact the inner wall of the sleeve, providing temporary space when the first and second damping rings are compressed and deformed, so as to ensure that the compression and recovery process can be carried out effectively, thereby achieving good energy dissipation effect.

[0012] like Figure 1 As shown, this utility model proposes: a damped buckling composite high-efficiency seismic bracing structure, including a support component A and a core rod 1 provided thereon; the support component A and the core rod 1 can be the support component and cross core plate of "CN202220854783.X" in the background art, respectively; It also includes a sleeve 2, with a through-hole 3 at the right end of the sleeve 2, through which part of the core rod 1 extends into the sleeve 2; a through-hole 3 is provided in the middle of the right end of the sleeve 2, and the through-hole 3 is smaller than the opening of the sleeve 2, so that the left end of the core rod 1 can move through the through-hole 3 and extend into the sleeve 2. The outer side of the core rod 1 is surrounded by a pressure ring 4 and a limiting ring 5, both of which are located inside the sleeve 2. The pressure ring 4 is located to the left of the limiting ring 5. A first washer 6 and a second washer 7 are fixed inside the sleeve 2, with a gap between them surrounding the core rod 1. As shown in the figure, the inner ring ends of the pressure ring 4 and the limiting ring 5 fix the core rod 1. The outer ring surfaces of the pressure ring 4 and the limiting ring 5 are at a distance from the inside of the sleeve 2, and the pressure ring 4 and the limiting ring 5 move left and right with the core rod 1 inside the sleeve 2. The outer ring ends of the first washer 6 and the second washer 7 are fixed to the inner wall of the sleeve 2, while the inner ring surfaces of the first washer 6 and the second washer 7 are at a distance from the outer side of the core rod 1. The pressure ring 4 is located between the first washer ring 6 and the second washer ring 7, and the limiting ring 5 is located between the first washer ring 6 and the right end of the sleeve 2. There is a first gap between the first washer ring 6 and the right end of the inner wall of the sleeve 2 for the limiting ring 5 to move, and there is a second gap between the second washer ring 7 and the left end of the inner wall of the sleeve 2 for the core rod 1 to move. The limiting ring 5 moves to fit the first washer ring 6 and the right end of the inner wall of the sleeve 2. When the core rod 1 moves, it can drive the limiting ring 5 to move left and right in the first gap, and the core rod 1 moves to the left in the second gap. A first damping ring 8 and a second damping ring 9 are respectively provided between the pressure ring 4, the first pad ring 6, and the second pad ring 7. The first damping ring 8 and the second damping ring 9 are sleeved on the outside of the core rod 1, and the left end of the core rod 1 does not contact the left end of the inner wall of the sleeve 2. The first damping ring 8 and the second damping ring 9 are sleeved on the outside of the core rod 1 to provide energy dissipation effect. The second damping ring 9 contacts the pressure ring 4 and the second washer 7; the first damping ring 8 contacts the pressure ring 4 and the first washer 6; the limiting ring 5 does not contact the first washer 6; the limiting ring 5 does not contact the right end of the inner wall of the sleeve 2. Figure 1 As shown, the left and right ends of the second damping ring 9 contact the second pad ring 7 and the pressure ring 4, and the left and right ends of the first damping ring 8 contact the pressure ring 4 and the first pad ring 6. This ensures that when the core rod 1 is displaced, the pressure ring 4 quickly applies pressure to the first damping ring 8 or the second damping ring 9, ensuring the same energy dissipation effect regardless of whether it moves left or right, thus improving the damping effect during left and right swings. At the same time, the pressure on the first damping ring 8 and the second damping ring 9 is both left and right pressure, which ensures that the amount of compressive deformation provided by the first damping ring 8 and the second damping ring 9 is large, which can effectively dissipate energy for larger vibration amplitudes and improve the damping effect. Meanwhile, the second damping ring 9, pressure ring 4, and second washer 7, as well as the first damping ring 8, pressure ring 4, and first washer 6, can also be connected in a fixed manner, so that when the core rod 1 is pulled left and right, the two sets of first damping rings 8 or second damping rings 9 can jointly provide the energy dissipation effect of deformation to improve the shock absorption capacity; the second damping ring 9, pressure ring 4, and second washer 7, as well as the first damping ring 8, pressure ring 4, and first washer 6 can be fixed by using the vulcanization process of "CN202220854783.X", or by directly using mechanical fasteners (such as screw through-connection fixation) or other fixable methods; The aforementioned limiting ring 5 will contact the right end of the inner wall of the sleeve 2 when the core rod 1 continues to move to the right, and the limiting ring 5 will contact the first pad ring 6 when the core rod 1 continues to move to the left, thereby limiting the excessive swing of the core rod 1 to the left and right. The displacement length is set while ensuring the effective deformation of the first damping ring 8 or the second damping ring 9, so as to protect the service life of the first damping ring 8 or the second damping ring 9. There is a deformation gap between the outer periphery of the first damping ring 8 and the inner wall of the sleeve 2; there is a deformation gap between the outer periphery of the second damping ring 9 and the inner wall of the sleeve 2; as shown in the figure, the outer ring ends of the first damping ring 8 and the second damping ring 9 do not contact the inner wall of the sleeve 2, providing temporary space when the first damping ring 8 and the second damping ring 9 are compressed and deformed, so as to ensure that the compression and recovery process can be carried out effectively, thereby achieving good energy dissipation effect.

[0013] The first damping ring 8 and the second damping ring 9 are made of butyl rubber or neoprene rubber, which have good damping characteristics, aging resistance, good chemical stability and high mechanical strength.
