This stop device can adapt simultaneous the fluctuation and the rotation of abutment, when the bridge receives too big earthquake horizontal force, only needs to change shearing pin, needn't carry out the back timber and change whole support, and maintenance when having overcome stop device and destroying, replacement cycle be long, spend high shortcoming.
Description
Technical field
The utility model relates to belonging to bridge technology field, particularly relates to one and can adapt to abutment and move up and down, and has the bridge stopping means of the restriction lateral or longitudinal movement of certain corner requirement.
Background technology
At present, in science of bridge building field, under the effect of earthquake or other loads, in order to limit the horizontal displacement of beam body, generally we use the mode arranging horizontal limit devices.It is current that to apply most in engineering be the cross spacing measure arranged to prevent bridge lateral under geological process from falling beam or the security that ensures seat structure, the most wide variety of Antivibration block, Antivibration block is as stopping means, it is generally located on the anti-quaking structure thing being placed in beam-ends both sides on bridge pier or abutment, the buffer body such as chock or rubber cushion blocks is set between Antivibration block and beam body.Antivibration block typically has armored concrete and two kinds of forms of steel construction.
The problem existed:
1. it is designed as integrated mechanism owing to existing highway bridge bearing bears the positive stop of horizontal force with support body, when excessive horizontal earthquake power causes bearing positive stop to occur surrender even to destroy, overall bearing can not be continuing with (many bridge pads are all owing to block destruction or anchors shearing cause whole bridge pad can not continue to re-use), back timber must be carried out and change overall bearing, so, on the one hand huge manpower and materials are expended, on the other hand long due to maintenance or replacement cycle, it is unfavorable for that the fast quick-recovery of bridge is properly functioning；
2. in the actual application practice of science of bridge building, the particularly bridge majority of cable-stayed bridge is in floating and half floating state, therefore there will be and move up and down and the situation of small angle rotation, above general type stopping means cannot adapt to pontic and fluctuate and two conditions of small angle rotation.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of reasonable in design, and convenient maintenance and replacement can adapt to a kind of bridge stopping means that abutment fluctuates, rotates, to overcome the above-mentioned deficiency existing for prior art simultaneously.
Solve above technical problem to adopt the technical scheme that: a kind of bridge stopping means, including shear and wind resistance pot bearing；
Described shear includes base plate, supporting plate, shear pin, cover plate, shearing pin plate and push plate；Described supporting plate is connected in parallel at the top of base plate, cover plate and shearing pin plate are arranged on supporting plate, the cover plate being close to supporting plate is connected by the connection securing member of both sides and supporting plate are fixing, shear pin plate to be arranged in the guide rail in the middle of cover plate end face, one end of shearing pin plate is fixing with the push plate being vertically set on shear side to be connected, when push plate is by external force pushing tow, push plate drives shears pin plate along slide；
Have pin-and-hole on described shearing pin plate and cover plate, in described pin-and-hole, with embedded mode, shear pin is installed；
Described wind resistance pot bearing is mounted vertically in the outside of push plate, and including upper steel plate and lower steel plate, the lower steel plate of wind resistance pot bearing is connected with the push plate of shear by bolt.
Further technical scheme is: the pin-and-hole on described shearing pin plate and cover plate is 1～3, and being arranged on the shear pin in pin-and-hole accordingly is 1～3.
Further: on the base plate below described push plate, limited block is installed.
Being provided with the sliding friction pair being made up of tetrafluoro slide plate and corrosion resistant plate between upper steel plate and the lower steel plate of described wind resistance pot bearing, described corrosion resistant plate is welded on upper steel plate, and described tetrafluoro slide plate is embedded on lower steel plate.
Owing to taking above technical scheme, the one bridge stopping means of the utility model has the advantages that
1. the one bridge stopping means of the utility model includes wind resistance pot bearing and shear, abutment can be adapted to fluctuate and rotate simultaneously, the sliding pair that tetrafluoro slide plate in wind resistance pot bearing and corrosion resistant plate are formed meets the requirement that abutment moves up and down, and the intrinsic characteristic of wind resistance pot bearing can meet the requirement that abutment deflection is not more than 0.2rad；
2. an a kind of bridge stopping means includes wind resistance pot bearing and shear, when bridge force-bearing is more than the design destructive power of shear pin, push plate promotes shears pin plate by shear pin, only need to again change shear pin can normally use, the back timber operation that need not carry out complexity changes overall bearing, overcomes maintenance when stopping means destroys, replacement cycle length, spends the shortcomings such as high；And shear pin is arranged on embedded mode in the pin-and-hole shearing pin plate and cover plate, directly the shear pin after disrumpent feelings is taken out when changing shear pin and again embed new shear pin, change conveniently, efficient height, low cost.
With embodiment, the technical characteristic of a kind of bridge stopping means of the utility model is further described below in conjunction with the accompanying drawings.
