Structural three-dimensional shock isolation and anti-overturning device

Abstract

The invention relates to a structural three-dimensional shock isolation and anti-overturning device. The main body mechanism of the device is formed by connecting a laminated rubber shock isolation support and a spring shock isolation support in series, and an upper connecting plate and a lower connecting plate are respectively arranged on the upper and lower sides of the main body mechanism. The device is characterized in that: a tensile steel wire rope uniformly distributed on four sides of the main body mechanism is arranged between the upper connecting plate and the lower connecting plate, and the limit deformation of the tensile steel wire rope in the horizontal direction is greater than the horizontal shearing elastic deformation of the main body mechanism. Through the device, the tensile strength of a common three-dimensional shock isolation device is improved, and swing of a high-rise building in an earthquake and even huge tension generated by overturning are resisted; meanwhile, because external tensile steel wire ropes are adopted, the device is convenient to mount and replace and has lower replacing expense.

Description

technical field [0001] The invention relates to a structural three-dimensional shock-isolation and anti-overturning device. Background technique [0002] On September 11, 2006, the State Intellectual Property Bureau authorized and announced the utility model patent of "improved three-dimensional shock-isolation bearing". The structure is connected in series, and it is characterized in that at least three flexible tensile members are evenly distributed around the symmetrical center line in the rubber pad, the middle part of the flexible tensile member is bent and placed in the central hole of the rubber pad, and the two ends are fixed on the rubber pad. On the upper and lower ends; the extension length of the flexible tensile member is not greater than the elastic deformation of the rubber pad; The upper end of the sleeve extends inwards-an annular flange clamps the lower connecting plate in it, and an annular buffer pad is arranged between the annular flange and the lower c...

AI Technical Summary

Problems solved by technology

[0004] Although the above two patents can relatively effectively resist the tension generated by the swaying or even overturning of high-rise isolation buildings during an earthquake, the tensile capacity of the support is limited due to the built-in flexible tensile members, and maintenance and replacement are inconvenient. , after an earthquake, the entire bearing needs to be replaced, which is uneconomical
