Embodiment Construction

[0016] see Figure 1-3 , The shape memory alloy self-resetting multi-dimensional shock-isolation bearing is a multi-dimensional shock-isolation (damping) device used in the field of civil engineering. The support is mainly composed of a support upper steel plate 1, a support lower steel plate 2, a support core cylinder 3, a support outer cylinder 4, a supporting shape memory alloy rod (cable) 5, a balanced shape memory alloy rod (cable) 6 and some Connecting components etc.

[0017] The steel plate on the support is welded to the core tube of the support, the steel plate on the lower support is welded to the outer tube of the support, a certain distance is left between the bottom of the core tube of the support and the top of the steel plate under the support, and the supporting shape memory alloy rod 5 is connected to the core tube of the support 3 and the bearing outer cylinder 4 are hinged. All supporting shape memory alloy rods (cables) 5 in the support are always in a s...

Abstract

The invention discloses a shape memory alloy self-resetting multi-dimensional shock insulation support which is characterized by comprising a support upper steel plate (1), a support lower steel plate (2) arranged opposite to the support upper steel plate (1), a support core cylinder (3) connected with the lower surface of the support upper steel plate (1) and a support outer cylinder (4) connected with the upper surface of the support lower steel plate (2), wherein the support core cylinder (3) is positioned in the support outer cylinder (4), the shock insulation support further comprises a support shape memory alloy rod (5) and a balance shape memory alloy rod (6) which are positioned in the support outer cylinder (4); and the two ends of the support shape memory alloy rod (5) are hinged with the support outer cylinder (4) and the support core cylinder (3) respectively, and the two ends of the balance shape memory alloy rod (6) are hinged with the support outer cylinder (4) and the support core cylinder (3) respectively. The shape memory alloy self-resetting multi-dimensional shock insulation support has the advantages of simple structure, good shock insulation and energy consumption effects and good durability.

Description

technical field [0001] The invention relates to a support for multi-dimensional isolation and shock absorption of engineering structures, which belongs to the technical field of anti-seismic load control devices for civil engineering structures. 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] Seismic isolation is the earliest passive control method studied and applied at home and abroad, and a large number of experimental studies, actual engineering construction and multiple strong earthquake tests have pro...
