A separate sliding tension device for shock-isolation bearings

Abstract

The invention discloses a separating sliding anti-tension device for an isolation bearing. The device comprises a separating sliding anti-tension device body and the horizontal isolation bearing. The separating sliding anti-tension device body is arranged at the periphery, between an upper steel plate (2) and a lower steel plate (3), of the horizontal isolation bearing. The horizontal isolation bearing comprises an isolation bearing body (1), the upper steel plate (2) and the lower steel plate (3). The isolation bearing body (1) is arranged in the middle between the upper steel plate (2) and the lower steel plate (3). The separating sliding anti-tension device body comprises a sliding rail (4), a sliding rod (5), a sliding block (6), a steel strand (7) and a supporting member (8). The upper end of the steel strand (7) is in rigid connection with the upper steel plate (2). The lower end of the steel strand (7) is in rigid connection with the sliding block (6). The sliding block (6) is installed on the sliding rod (5). The sliding rod (5) is arranged on the sliding rail (4). The sliding rail (4) is fixed to the lower steel plate (3) through the supporting member (8). According to the separating sliding anti-tension device for the isolation bearing, the horizontal earthquake action is isolated through the horizontal isolation bearing, and structural vibration formed under a horizontal earthquake is reduced.

Description

technical field [0001] The invention relates to a separate sliding tension-resistance device of a shock-isolation support, which is suitable for shock-isolation of high-rise buildings and building structures with a large aspect ratio after being assembled and combined with a horizontal shock-isolation support. Background technique [0002] Earthquake disasters bring immeasurable loss of life and property to human beings. The base isolation system is to install some kind of isolation and energy dissipation device between the upper structure and the foundation to reduce the transmission of seismic (vibration) energy to the upper part and achieve the purpose of reducing structural vibration. [0003] The horizontal isolation technology of building foundation has been widely used in various middle and low-rise buildings, and has achieved good shock absorption effect. However, due to the large overturning moment generated by the horizontal seismic force of high-rise and super hi...
