Description
Technical field
The present invention relates to bridge pad field, and in particular to a kind of bridge earthquake resistance bridle iron.
Background technology
It is relatively simple, economical and effective earthquake resistant engineering technology in science of bridge building to subtract seismic isolation technology, subtracts shock insulation by setting
Device carrys out the extending structure cycle, and increases damping to reduce the energy that earthquake is delivered to agent structure, avoids the damage of agent structure
Wound.
The seismic isolation device commonly used at present in science of bridge building is vibration absorption and isolation support, mostly natural rubber bearing, lead-rubber
Bearing and friction pendulum support.Natural rubber bearing, lead core rubber support are because, as main loading material, being had and being passed using rubber
The problems such as power is unreliable, stability is poor and damps skewness；And the distinctive sliding surface of friction pendulum support is to manufacturing process
Propose very high requirement.These problems limit backed application, and there is an urgent need to one kind to have compared with Gao Cheng
Carry power, damping is evenly distributed, manufactures the novel bridge aseismatic bearing of simplicity.
The content of the invention
The invention provides a kind of bridge earthquake resistance bridle iron, vertical bearing capacity is higher, damping is evenly distributed, manufacturing process letter
Just, and there is the characteristics of two-way antidetonation, can effectively alleviates percussion of the earthquake to girder.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of bridge earthquake resistance bridle iron, including it is interconnected as the lower steel plate and middle steel plate of an entirety；The centre
The groove of annular is provided with steel plate, the two side of groove is bonded with flexure strip；Multiple cylinder lead for retractable pencils are provided with groove；Upper steel
Plate is located at the top of middle steel plate, and upper steel plate at the top of cylinder lead for retractable pencil with being fixedly connected；Set between upper steel plate and middle steel plate
There is sliding layer, sliding layer includes the stainless steel plate and plane polyfluortetraethylene plate of stacked on top.
According to such scheme, the outer surface of the middle steel plate is fixedly connected with the steel shoe of annular；The upper steel plate
Edge is downwardly protrude to form limitting casing, and the bottom of limitting casing contacts with steel shoe, and rubber is provided between limitting casing and middle steel plate
Ring.
According to such scheme, the outer surface of the cylinder lead for retractable pencil is enclosed with rubber cover.
Compared with prior art, the beneficial effects of the invention are as follows：The upper steel plate that geological process makes to be connected with girder passes through cunning
Dynamic layer slides, and makes yield deformation after cylinder lead for retractable pencil stress, effectively alleviates earthquake to the level of girder to active force, avoids occurring
Fall beam disaster.Flexure strip can make the cylinder lead for retractable pencil after deformation recover deformation, and rubber ring can be further ensured that cylinder lead for retractable pencil
Recover deformation, make the present invention that there is reusability.Lower steel plate, middle steel plate and upper steel plate in the present invention are steel
Material, has higher vertical bearing capacity, can carry the larger beam body of quality；The settable cylinder lead for retractable pencil of vertical, horizontal of the present invention,
The characteristics of making it have two-way antidetonation.
Brief description of the drawings
Fig. 1 is the structural representation of biopsy cavity marker devices of the present invention；
Fig. 2 is the structural representation of the positive cutting of the present invention；
Fig. 3 is the structural representation that the present invention overlooks cutting.
Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings, each label is interpreted as in figure：1-
Upper steel plate, 2- rubber covers, 3- cylinder lead for retractable pencils, 4- stainless steel plates, 5- plane polyfluortetraethylene plates, 6- steel shoes, in 7-
Between steel plate, 8- lower steel plates, 9- flexure strips, 10- rubber rings, 11- grooves.
The present invention includes the lower steel plate 8 and middle steel plate 7 being welded as a whole mutually.
The groove 11 of annular is provided with middle steel plate 7 close to edge, the two side of groove 11 is bonded with flexure strip 9.
Cylinder lead for retractable pencil 3 is additionally provided with groove 11, the outer surface of cylinder lead for retractable pencil 3 is enclosed with rubber cover 2.
Upper steel plate 1 is located at the top of middle steel plate 7, upper steel plate 1 be connected with the top of cylinder lead for retractable pencil 3 to be formed one it is whole
Body.
Sliding layer is provided between upper steel plate 1 and middle steel plate 7, sliding layer includes stainless steel plate 4 and plane polytetrafluoroethylene (PTFE)
Plate 5.
The outer surface of middle steel plate 7 is welded with the steel shoe 6 of annular.The edge of upper steel plate 1 is downwardly protrude to form limitting casing,
The bottom of limitting casing is contacted with steel shoe 6, and rubber ring 10 is provided between limitting casing and middle steel plate 7.
Lower steel plate 8 is fixed on bridge pier, and upper steel plate 1 is fixedly attached together with girder.When seismic wave arrives, upper steel plate
Sliding layer between 1 and middle steel plate 7 produces sliding, is produced between stainless steel plate 4 and plane polyfluortetraethylene plate 5 relatively sliding
Dynamic, cylinder lead for retractable pencil 3 produces the plastic deformation of hysteresis damping and absorbs seismic energy.After earthquake terminates, provided by flexure strip 9
Horizontal restoring force, cylinder lead for retractable pencil 3 is returned to original position.Rubber ring 10 provides cylinder lead for retractable pencil 3 further horizontal extensive
Multiple power, while rubber ring 10 is also avoided that the limitting casing of middle steel plate 7 and upper steel plate 1 directly hits, that improves whole bearing can
By property.
Rubber cover 2 is avoided that side wall impact of the cylinder lead for retractable pencil 3 directly with groove 11, avoid cylinder lead for retractable pencil 3 with
The middle steel plate 7 of hardness is directly hit so as to damage cylinder lead for retractable pencil 3, influences damping performance；On the other hand, rubber cover 2
Also buffering can be played a part of to the plastic deformation of cylinder lead for retractable pencil 3, avoids cylinder lead for retractable pencil 3 from deforming and excessively acutely damage.
The particular number of the inner cylinder lead for retractable pencil 3 of groove 11 can be set, cylinder according to local highest horizontal earthquake over the years
The quantity of body lead for retractable pencil 3 is more, and shock resistance is stronger.Accordingly, the thickness of rubber ring 10 can be also arranged to according to horizontal earthquake
Different thickness, the buffering and recovery capability that thicker rubber ring 10 plays are stronger.
Lower steel plate 8, middle steel plate 7 and upper steel plate 1 in the present invention are Steel material, have higher vertical bearing capacity,
The larger beam body of quality can be carried.The sliding layer that stainless steel plate 4 and plane polyfluortetraethylene plate 5 form has the friction of very little
Power so that when earthquake occurs, cylinder lead for retractable pencil 3 can react rapidly, yield deformation after stress, effectively alleviate earthquake to girder
Percussion, avoid beam disaster.
