Abstract

The invention relates to the technical field of seismic reduction engineering, and discloses a seismic isolation support capable of rolling and swinging in two directions for seismic reduction engineering. The seismic isolation support comprises a side plate, wherein limiting grooves are formed in the inner side of the side plate, seismic reduction mechanisms are arranged in the two sides of the side plate, a first placing plate is connected to the interior of the side plate in a sleeving mode, and limiting blocks are welded to the end, close to the side plate, of the first placing plate. Through arrangement of the seismic reduction mechanisms, limiting springs, the limiting grooves and the limiting blocks, the seismic reduction effect is improved to the maximum extent by comprehensively utilizing the horizontal, vertical and rotary seismic reduction and isolation modes; by arranging rotating shafts, first connecting rods and second connecting rods, the application range of the seismic isolation support is greatly widened, and the protection effect is improved; and through the arrangement of the limiting grooves, the limiting blocks and rolling shafts, the maximum corner displacement can be limited, the anti-pulling-off capacity is achieved, the safety and stability of the structure are improved, the risks of beam falling, support disengagement and the like are greatly reduced, and meanwhile, through the cooperative use of the limiting grooves and the limiting blocks, the good post-earthquake self-resetting characteristic is achieved.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing engineering, in particular to a two-way rolling pendulum shock-isolation support for shock-absorbing engineering. Background technique [0002] Earthquakes are frequent natural disasters. Because my country is located in the two major earthquake-prone areas of the Pacific Rim and the Eurasian belt, earthquakes have become the primary natural disaster that threatens the safety of people's lives and property. In order to reduce the damage caused by earthquakes, engineers introduce shock-absorbing and isolating devices into building structures. At present, actual projects usually use shock-absorbing and isolating bearings to reduce the damage caused by earthquakes to building structures. In civil engineering structures, shock-absorbing and isolating bearings can effectively block the transmission of vibration energy and consume the energy released by vibration, thereby significantly reducing t...
