Embodiment 1

[0033] Embodiment 1: as Picture 1-1 and 1-2 As shown, a shape memory alloy strand shock absorber includes a steel plate, an L-shaped steel plate 1-4, an L-shaped connecting steel plate 1-3, a first limiting plate 1-5, a second limiting plate 1-8, Steel blocks 1-6 with cuboid holes and slots reserved, polytetrafluoroene slide plates and stranded wires 1-7 of shape memory alloy. The steel plate and the L-shaped steel plate 1-4 are connected by the L-shaped connecting steel plate 1-3, and the L-shaped connecting steel plate 1-3 is welded to the L-shaped steel plate 1-4 while being anchored to the upper steel plate 1-1 with bolts and nuts, forming The first steel plate group. One side of the steel blocks 1-6 with cuboid reserved holes and slots is welded with the steel plate, and the other side is welded with the limiting plate, and the corresponding size limiting plate is also inserted in the reserved slot to form the second steel plate group. The installation method of the sh...

Embodiment 2

[0047] Embodiment 2: as diagram 2-1 As shown, an assembled anti-buckling support uses a shape memory alloy material. The shape memory alloy has superelasticity, high damping, corrosion resistance and memory effect, so after the earthquake, the invention can reset itself, because it is assembled Therefore, it is easy to disassemble, easy for daily maintenance and post-earthquake repair. It includes an upper steel plate 2-2 with screw holes, a shape memory alloy spring 2-7, a cross-shaped long steel core with grooves 2-5, a steel plate group with screw holes 2-3, and a circular steel pipe 2- 6. Rectangular steel bar 2-4, bolt 2-1.

[0048] Further, the steel plate group 2-3 with screw holes includes a hollow rectangular body formed by a vertical plate and a bottom plate, the top surface of the vertical plate has screw holes, and the steel plate group 2-3 also includes several small U-shaped steel plate groups 2-3 percent, several small U-shaped steel plates are divided into t...

Embodiment 3

[0058] Embodiment 3: as Figure 3-1 , Figure 3-2 As shown, a ring-shaped shape memory alloy spring omnidirectional shock-isolation support includes a circular outer cylinder, a circular inner cylinder, a limit plate 3-6, an annular shape memory alloy spring 3-3, a rectangular steel plate 3-4, a circular Steel plate 3-5, circular steel plate 3-5 are used as upper connecting steel plate. The lower part of the annular shape memory alloy spring 3-3 is composed of three inner and outer cylinders 3-1. An annular shape memory alloy spring 3-3 is placed between the inner and outer cylinders 3-1, and a limit plate 3-6 is installed above to prevent the inner and outer cylinders 3-1 from breaking away. The surface of the bottom surface of the outer cylinder 3-1 is inlaid with polytetrafluoroethylene slide plates to reduce the coefficient of friction. The upper part of the shock-isolation support is composed of circular steel plates and rectangular steel plates, which are connected by...

Abstract

The invention relates to a combined shock insulation method and belongs to the field of shock resistance of building engineering structures. In order to solve the problem of poor vertical damping effects and small lateral energy consumption of existing shock insulation supports, shock insulation and energy consumption are performed in vertical and transverse directions. The effect is to consume energy in both directions.

Description

technical field [0001] The invention belongs to the anti-seismic field of construction engineering structures, and relates to a shock-isolation and shock-absorbing bearing. Background technique [0002] Earthquake action is the main control load borne by civil engineering structures, and it is also the main factor leading to the damage and collapse of structures. Accurately understanding the response of structures under earthquake action and taking reliable protection measures is not only related to the seismic performance of the structure itself, but also directly related to the safety of people's lives and national economic property, which has huge social and economic benefits. [0003] For seismic isolation bearings, it can be roughly divided into two categories: rubber isolation bearings and sliding isolation bearings. Among them, the natural interlayer rubber bearing has a large vertical stiffness, the vertical deformation is small when bearing the weight of the buildi...
