Abstract

The invention belongs to the technical field of shock isolation, in particular to an overturn preventing device of a building shock isolation support. The device comprises a transverse buckling member, a longitudinal buckling member, an upper pre-embedding member and a lower pre-embedding member. The tops of the transverse buckling member and longitudinal buckling member are of box beam structures, and two sides of the bottoms are provided with baffles; high damping rubber blocks are fixed to the near ends of the transverse buckling member and longitudinal buckling member, and the tail ends of the baffles are fixed to T-shaped reinforcement plates; the transverse buckling member and the longitudinal buckling member are arranged in a crossed manner horizontally, and the transverse buckling member is located above the longitudinal buckling member; a box type connector is fixed above the longitudinal buckling member; the bottom of the transverse buckling member is fixedly connected to the lower embedding member, and the box type connector is fixedly connected to the upper embedding member. The overturn preventing device is reliable in structure and convenient to install, the shock isolating performance is not affected, vertical bearing force and tensile stress are provided during strong shocks, the shock isolation support is protected from being damaged by vertical tensile stress and horizontal shearing stress, and overturning hazards caused by building gravity center shifting can be avoided effectively.

Description

Technical field [0001] The invention belongs to the field of seismic isolation technology, and specifically relates to an anti-overturning device for a building seismic isolation support. Background technique [0002] In the earthquake zone, the seismic isolation supports 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 the building or bridge caused by the earthquake disaster. However, the structural characteristics of the seismic isolation support determine that its tensile strength is very low, especially the vertical tensile strength is poor, and its ultimate tensile strength is only 6% to 8% of the ultimate compressive strength. When a strong earthquake occurs, the seismic isolation support of the building will produce huge tensile stress under the simultaneous action of the horizontal and vertical earthquakes, which will cause the isolation ...
