Description
Technical field
The invention belongs to bridge earthquake resistance technical fields, and in particular to a kind of suitable bridge for bridge is consumed to low-yield steel
It can type bridge shock-proof check block structure and method for arranging.
Background technique
China is one of more earthquake countries in the world, the ground of generation between Pacific Ocean earthquake zone and Eurasian earthquake zone
Shake has the characteristics that intensity is big, distribution is wide, focus is shallow and earthquake especially severe.The bridge many places built are in the hinge of highway communication
Status and throat location, are the important component of lifeline engineering, once being destroyed in earthquake, consequence is catastrophic
, the severe paralysis of entire traffic system is resulted even in sometimes, is made troubles to subsequent rescue and reconstruction.In the past
In the violent earthquake occurred in decades, the earthquake form of bridge specifically includes that support damages；The upper beam position of beam bridge moves such as
Fruit has exceeded the supporting surface of bridge pier, then can cause to fall beam earthquake (containing direction across bridge and along bridge to)；Top beam body falls Liang Shiru
Fruit hits bridge pier, the impact wreckage for causing substructure very big；Local damage caused by adjacent Beam pounding at expansion joint；It is flexible
Relatively large impact force can also pass to the collision stress effect at this bridge pier bottom, cause the damage of bridge pier bottom at seam；Bridge
The local damage of beam Antivibration block itself, to lose the function of seismic resistance of block.
The bridge in China is at present in order to limit the relatively large displacement of top beam body direction across bridge, usually at the top of pier cap beam
Reinforced concrete block is installed, and it is relatively fewer along the research of bridge to relatively large displacement to limitation top beam body.But earthquake
Bridge also it occur frequently that beam body along bridge to fall beam damage.Collision between common reinforced concrete block and beam body is mixed
Rigid collision between solidifying soil, be easy to cause the local damage of reinforced concrete block and bridge beam body, and reinforcing bar in earthquake
The horizontal shear of concrete block is usually insufficient, and block is easy to happen the destruction of unrepairable, cannot limit the position of beam body very well
It moves.But if reinforce the bonding strength between concrete block and bent cap, and the collision effect between block and beam body can be shifted
To bridge pier bottom, cause the damage of bridge pier bottom.Additionally earthquake centre, for the beam bridge at expansion joint, biggish upper beam is arranged
Body can also cause direct collision of the adjacent beam at expansion joint to displacement along bridge, and it is broken not only to generate serious part in collision area
It is bad, it also will increase the normal pass of the widths affect vehicle at expansion joint.
In view of the above deficiencies, need to design and develop a kind of novel suitable bridge to anti-seismic stop structure, it can not only be generation
Rigid collision between block and beam body is converted into flexible impact, moreover it is possible to effectively reduce impact force and earthquake energy.
Summary of the invention
In view of the drawbacks described above of the prior art, the present invention designs and develops a kind of novel anti-seismic stop structure and arrangement side
Method limits along bridge to displacement relatively large between beam body and bridge pier, protects support, prevent beam body along bridge to fall beam earthquake；
The rigid collision occurred between block and beam body is converted into flexible impact, greatly reduces the local damage of collision area；?
Collision at expansion joint between adjacent beam body is transferred on block, has the function that protect expansion joint；Increase and disperses beam body and gear
Position of collision between block greatly reduces the impact force for acting on each stop block structure, reduces the local damage of stop block structure；To the greatest extent
Seismic energy being consumed possible, to reduce the damage of other bridge members such as bridge pier more.
To achieve the above object, the technical scheme is that, a kind of suitable bridge is anti-to low-yield steel energy-dissipating type bridge
Shake stop block structure, it is characterised in that: including steel corbel, block block and steelframe；Steel corbel is fixed near bridge movable bearing support
Pier coping portion side, block block is welded on steel corbel；Steelframe is fixed on the bottom of the girder of bridge, and block block is located at
Between two steelframes, a certain distance is reserved between block block and steelframe.
More excellent distance between the block block and steelframe is 20mm -80mm.
The block block is added by block block steel sole plate, block block steel side plate, block block steel web, block block
Strength rib, energy-dissipating type low yield point steel plate and collision steel plate are formed by welding；Two pieces of opposite block block steel plate-side plate weldings are in block
On block steel sole plate, one piece of energy-dissipating type Low Yield Point Steel is successively welded between two blocks of opposite block block steel side plates from bottom to top
Plate, one piece of block block ribbed stiffener and one block of block block steel web, every piece of block block steel side plate outside and block block add
One block of collision steel plate is respectively welded on the mutually level horizontal position of strength rib, it is arc-shaped for colliding the most edge of steel plate.
The steelframe is welded by steelframe ribbed stiffener, steelframe side plate, steelframe web and steelframe top plate；Steelframe top plate is opened
There are several bolts hole；Horizontal steelframe top plate welds downwards two blocks of vertical and opposite steelframe side plates, two blocks of steelframe side plates
Between welding steel structure ribbed stiffener and steelframe web；Steelframe ribbed stiffener is parallel with steelframe top plate, and steelframe web and steelframe top plate are vertical.
The yield strength of energy-dissipating type low yield point steel plate in the block block will be lower than in block block in addition to energy consumption
The yield strength of other steel other than type low yield point steel plate, in block block other than energy-dissipating type low yield point steel plate
The yield strength of other steel is identical with steel corbel, the yield strength of steel of steelframe is constituted.
The energy-dissipating type low yield point steel plate uses yield point for the Low Yield Point Steel of 160MPa or 100MPa.
Method for arranging of the suitable bridge to low-yield steel energy-dissipating type bridge shock-proof check block structure, which is characterized in that
The bridge shock-proof check block structure direction across bridge is arranged near each bridge movable bearing support, and stop block structure arrangement is more and disperses,
The distance between block block and steelframe, which are less than movable bearing support, allows mobile maximum distance, achievees the purpose that protect support；It is right
Beam bridge in setting expansion joint, the distance between block block and steelframe are also less than the width at expansion joint, can be in earthquake
Disperse position of collision, greatly reduces the seismic force acted in each bridge shock-proof check block structure, it can be should occur stretching
Collision at contracting seam between adjacent beam body is transferred on block, prevents the damaged in collision at expansion joint.
Above-mentioned method for arranging, further, the ribbed stiffener of the ribbed stiffener of block block, collision steel plate and steelframe will be aligned
Setting.
Its principle is: in earthquake, relatively large displacement occurs to beam body and bridge pier along bridge, when the displacement is more than block block
When the distance between body and steelframe, block block and steelframe collide, to limit along bridge to beam body and bridge pier relatively
Big displacement, restrainer damage.Contain 1 piece of energy-dissipating type low yield point steel plate in block block, yield strength is kept off lower than antidetonation
The yield strength of other steel in block structure, convenient in earthquake, energy-dissipating type low yield point steel plate first occurs than other general steel plates
Moderate finite deformation consumes energy.Seismic wave is there are three direction, and it is extremely complex to frequently result in bridge vibration of beam, block block and steelframe
Between collision be difficult to be aspectant uniform collision, be more the uncertain point-to-area non-uniform collision of position of collision.
Therefore, have two blocks of collision steel plates on block block, the most edge of the collision steel plate be it is arc-shaped, be thus able to satisfy bridge and exist
It is the uncertain point-to-area non-uniform collision of position of collision under complex vibration, is conducive to stop block structure normal work.
In order to further ensure that the energy-dissipating type low yield point steel plate in anti-seismic stop structure works normally, also to prevent block
Serious local damage, such as steel plate buckling do not occur for other steel plates in structure.Therefore, the collision area of block block in addition to
It is to also set up the ribbed stiffener of 1 piece of block block other than arc-shaped collision steel plate that most edge, which is arranged,；Similarly, the collision of steelframe
Region is also provided with the ribbed stiffener of 1 block of steelframe.The ribbed stiffener of the ribbed stiffener of block block, collision steel plate and steelframe, which will be aligned, to be set
It sets, makes position of collision at ribbed stiffener, steel plate is not susceptible to local buckling, and stop block structure is not susceptible to local damage.
The beneficial effects of the present invention are: the present invention can effectively limit between bridge beam body and bridge pier along bridge to it is relatively large
Displacement prevents beam body from falling beam damage, reduces the earthquake of movable bearing support and expansion joint.Because all being arranged near each movable bearing support
The bridge shock-proof check block, the position dispersion of block, quantity is more, such method for arranging can effectively reduce acts on it is every
Seismic force on one stop block structure reduces the damage to stop block structure itself.In addition, ribbed stiffener, collision steel in block block
Ribbed stiffener in plate and steelframe is aligned setting, makes position of collision at ribbed stiffener, is hardly damaged stop block structure.Collide steel plate most side
It is the uncertain non-uniform collision of position of collision that edge circular-arc-shaped design, which can effectively meet the collision between block and steelframe,.Medium and smallly
Shake effect under, lesser impact force makes the energy-dissipating type low yield point steel plate in block block be in elastic stage, the stage with
Ordinary reinforced concrete block is similar, belongs to rigid collision；But under violent earthquake effect, biggish impact force can make energy-dissipating type is low to bend
Clothes point steel plate enters the plastic stage, and the collision category flexible impact between block block and steelframe can not only effectively reduce collision
The local damage and reduction in area are transmitted to the damage of bridge pier bottom, may also rely on energy-dissipating type low yield point steel plate in block block
Plastic deformation, consume a part of seismic energy, reduce damage of the earthquake to other components of bridge.Finally, the present invention has material
