Description
Technical field
The present invention relates to bridge earthquake resistance technical field more particularly to a kind of multidirectional limit energy consumption Antivibration block knots of Self-resetting
Structure.
Background technique
China is located at two violent earthquake band of the world-- between circum-Pacific seismic belt and Eurasian earthquake zone, by Pacific Ocean plate
The extruding of block, Indian and Philippine Sea plate, Earthquake Fault Zone are very active.Since the 1980s, China into
Enter new Earthquake Activity Periods, earthquake occurrence frequency significantly improves.And the earthquake disaster in China has, and intensity is big, frequency is high, divides
The features such as cloth range is wide.Bridge is the important channel of communications and transportation, and the vibration of bridge floor can seriously affect the service life of bridge, is especially met
Earthquake disaster etc. is arrived, it is badly damaged to will cause bridge, leads to interruption of communication, causes heavy economic losses.China is built in recent years
A large amount of bridge, once destroying in earthquake, this not only will cause greatly to threaten to the people's lives and property, more will
Chinese society expanding economy is restrict, will also cause greatly to lose.
The bridge in China usually only limits direction across bridge to limit the relatively large displacement of top beam body at present, along bridge to or
The vertical relatively large displacement of person, and in actual seismic, the direction of displacement of beam body will not be only subjected to displacement in one direction,
Direction of displacement includes along bridge to, direction across bridge and vertical, so as to cause a variety of earthquake disasters, comprising: support damage, beam body occur
Fall beam damage, the damaged in collision at expansion joint, the vertical warpage damage of beam body, the vertical impact wreckage occurred between beam body and support
Deng.But China compares shortage to the research of the multidirectional limitation relatively large displacement of beam body.Shock-absorbing bridge support often all compares at present
Huger and heavy, when shock absorber part destroys, reparation is more troublesome, and the flexibility of replacement is lower.Have some smaller
Bridge pad, but damping effect is undesirable, especially when an earthquake occurs, for being imitated along bridge to the abatement with vertical energy wave
Fruit is very poor.Traditional reinforced concrete block self weight is excessive, and property is crisp, and reparation is inconvenient, is easy to happen the damage of unrepairable,
And the direction of limiting displacement is excessively single, can not be competent at the bridge earthquake resistance in earthquake actively area.
In order to make up above-mentioned defect, need to design and develop a kind of multidirectional limit energy consumption Antivibration block of novel Self-resetting
Structure can not only limit the multiple directions displacement of bridge beam body, moreover it is possible to generated energy wave and rise in effective dissipation earthquake
To the effect of Self-resetting.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of multidirectional limit energy consumption Antivibration blocks of Self-resetting
Structure can effectively limit earthquake Bridge beam body and bent cap and relatively large displacement occurs in a plurality of directions, avoid support by
Damage, restrainer earthquake, when an earthquake occurs, and the limiter elastic belt of block inboard side, height friction silicon rubber panel, damping
Spring and pulling force rope can effectively play buffer function, limit the displacement of beam body, moreover it is possible to which dissipate seismic energy, and it is anti-to play damping
The effect of shake；And the elasticity that can use structural material plays the effect of Self-resetting；Lead to beam body position when earthquake intensity is excessive
When moving past big, beam body will collide with block, to limit displacement, prevent to fall beam harm, reduce earthquake.
