Technical Field
The invention belongs to the technical field of building earthquake prevention, and particularly relates to a building earthquake prevention structure.
Background
China is the country with the most earthquakes in the mainland in the world, and two thirds of the mainland earthquakes in the world occur in China. Most provincial cities in China are located on earthquake zones, and the building fortification intensity of most cities is over 7 degrees, so that the requirement on the earthquake resistance of buildings is high.
The requirement of our country for the earthquake resistance of buildings is that the building can run under small earthquake and large earthquake. Even if an earthquake with super-strong destructive power occurs, the building is required to be incapable of immediately collapsing and sufficient time is required for escape to flow out.
the seismic waves comprise transverse waves and longitudinal waves, the longitudinal waves are high in propagation speed and small in destructive force, and the transverse waves are low in propagation speed and large in destructive force. Most building collapses are shaken and broken up by lateral oscillations caused by transverse waves. The existing building is mostly shockproof by adopting a building body reinforcing mode, such as a ring beam structure, and such as a cast-in-place mode. These measures reinforce the building body to a certain extent, but it is still difficult to resist earthquakes with an intensity of up to 11 degrees in shocks like Wenchuan. If the strength is increased, the construction cost is greatly increased, and the economical efficiency is poor.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
