Description
One, technical field:
The present invention is a kind of device that is used for antidetonation, shock insulation and the damping of civil engineering.
Two, background technology:
When earthquake takes place, ground motion will cause the vibration of engineering structures.For isolating or suppress the transmission of ground motion to superstructure, can be between basic end face and superstructure bottom or other correct position of engineering structures earthquake isolating equipment is set, with the power that reduces engineering structures anti-because of.Theoretical research, test and engineering practice show that all earthquake isolating equipment is the effective means that the civil engineering structure damping is taken precautions against natural calamities.Recent two decades comes, and has developed out multiple earthquake isolating equipment both at home and abroad and has been used for engineering practice.These earthquake isolating equipments comprise that rubber vibration isolation device (do not have bonding lead for retractable pencil laminated rubber earthquake isolating equipment, bonding lead for retractable pencil laminated rubber earthquake isolating equipment, variable cross-section lead-rubber earthquake isolating equipment and high damping ferrite rubber vibration isolation device are arranged), slippage are every the city device, specifically have a mixing earthquake isolating equipment that earthquake isolating equipment, friction pendulum-type earthquake isolating equipment, the sliding component of soft landing protection platform combine with the shock insulation pad etc.Above-mentioned earthquake isolating equipment can alleviate the structural vibration that seismic wave flatly causes effectively, thereby has been applied in engineering practice.Because the spatial movement of ground motion when earthquake takes place, except that level to seismic wave, vertical seismic wave has important destruction equally.Earthquake is investigated and to be shown, brick cigarette halogen is vertically folded near destruction (chimney bottom that the brick fragment is scattered), transformer and jumped out of earthquake such as its track and be due to the vertical earthquake.And present above-mentioned earthquake isolating equipment is the level of isolation earthquake, isolation to vertical seismic wave but cuts little ice, since vertical seismic wave and seismic wave flatly have identical magnitude to the structural damage effect, the invention vertical earthquake isolating equipment for engineering structure is badly in need of in group, resists the ability of vertical geological process with practical raising engineering structures.
Three, summary of the invention:
(1) goal of the invention
Purpose of the present invention just provides and a kind ofly can be used for isolating and suppress the civil engineering structure vibrations that vertical motion such as vertical seismic wave causes, increases substantially the vertical earthquake isolating equipment for engineering structure that engineering structures is resisted the ability to work of vertical geological process ability.
