Abstract

The invention belongs to the field of earthquake isolation technology, and in particular relates to an anti-overturning device for an earthquake isolation support of a building. The device includes a horizontal buckle, a longitudinal buckle, an upper embedded part and a lower embedded part. The proximal end of the baffle of the pull piece is fixed with a high damping rubber block, and the end of the baffle is fixed with a T-shaped reinforcing plate; the horizontal and vertical pull pieces are arranged in a horizontal cross, and the horizontal pull piece is located above the longitudinal pull piece; A box-shaped connecting piece is fixed above the longitudinal buckle and pull piece, and the lower part of the horizontal buckle-pull piece is fixedly connected with the lower embedded part; the box-shaped connecting piece is fixedly connected with the upper embedded part. The anti-overturning device has a reliable structure and is easy to install, and does not affect the isolation performance of the rubber bearing. When a strong earthquake occurs, it can provide vertical bearing capacity and tensile stress at the same time, and protects the isolation bearing from vertical tensile stress and horizontal shear. Shear stress failure can effectively prevent the overturning hazard caused by the shift of the center of gravity of the building.

Description

technical field [0001] The invention belongs to the field of earthquake isolation technology, and in particular relates to an anti-overturning device for an earthquake isolation support of a building. Background technique [0002] In earthquake areas, the seismic isolation bearings used for houses, bridges or other structures can effectively isolate the transmission of seismic energy to the upper structure when an earthquake occurs, thereby reducing the damage to buildings or bridges caused by earthquake disasters. However, the structural characteristics of the seismic isolation bearing determine that its tensile strength is very low, especially the vertical tensile capacity is poor, and its ultimate tensile strength is only 6% to 8% of the ultimate compressive strength. When a strong earthquake occurs, the building's isolation bearings will generate huge tensile stress under the simultaneous action of the earthquake's horizontal and vertical earthquakes, which will cause th...
