Anti-pulling, limiting and earthquake-insulating device integrated by guide rails and vertical ropes

Abstract

The invention discloses an anti-pulling, limiting and earthquake-insulating device integrated by guide rails and vertical ropes, wherein the device comprises an upper connection plate, a lower connection plate, a bearing main body, an upper guide rail, a lower guide rail, sliding blocks, limiting baffles and vertical ropes, wherein the vertical ropes are connected with the bearing main body in parallel; the upper guide rail and the lower guide rail are respectively connected with the upper connection plate and the lower connection plate; the upper guide rail and the lower guide rail are cross-shaped; sliding cavities are formed in the guide rails; the sliding blocks can slide in the cavities along the guide rails; the limiting baffles are arranged at two ends of the cavities; the vertical ropes are fixed between an upper sliding block and a lower sliding block. According to the anti-pulling, limiting and earthquake-insulating device, the sliding blocks slide along the guide rails; the ropes retain the vertical state all the time, so that the ropes can supply effective tension when a bearing of the device has the designed shear displacement; meanwhile, when the bearing has great deformation, the sliding blocks move to the limiting baffles; the ropes obliquely pull and can limit the continuous great deformation of the bearing, so that the anti-pulling and anti-overturning performances of building structures under the action of multi-dimensional earthquake and wind load can be improved.

Description

technical field [0001] The invention belongs to the technical field of seismic isolation of construction engineering, and mainly relates to a tensile and position-limiting seismic isolation device combined with a guide rail and a vertical cable. Background technique [0002] Rubber bearing isolation technology is a relatively mature isolation technology at present. However, due to the adhesive connection between the rubber and the steel plate inside the support, when the high-rise building is subjected to a vertical earthquake, or when the support has a large horizontal shear displacement, or when the height-width ratio of the building is large, the support is easy to be pulled. , and the rubber bearing is prone to tearing and damage between the rubber layer and the steel plate when it is pulled, which will affect the horizontal isolation performance of the bearing, or directly cause the building to overturn and fail. [0003] According to the requirements of the national s...
