Description
Technical field
The utility model relates to bridge earthquake resistances and field of shock absorption, and in particular to a kind of energy consumption of multiple protective girder girder falling
Device and preparation method thereof.
Background technique
In the late three decades, domestic and international earthquake disaster takes place frequently, and earthquake region traffic has been cut off in many bridge collapses or serious damage
Lifeline causes huge life and property loss；It include: to fall beam earthquake, branch in all previous earthquake Bridge typical damage form
Seat sliding, expansion joint destroy, block destroys, adjacent girder collides earthquake and abutment crack earthquake；Short/Medium Span Bridge is general at present
All over laminated rubber bearing is used, the sliding mechanism of laminated rubber bearing helps to reduce the seismic response of superstructure, and one
Determine to protect bridge pier and basis from biggish eaerthquake damage in degree；But in some highlight lines areas, bridge is made in earthquake
Biggish displacement will occur under, will lead to superstructure after displacement is more than permissible value and collide or fall beam earthquake, sternly
Ghost image rings the development of rescue work after shake.
Utility model content
In order to solve the above technical problems, the utility model provide a kind of multiple protective girder girder falling energy-consuming device and its
Production method is solved bridge and longitudinal and transverse bridge is easily occurred under geological process to substantially deviation using the combination of damping device and drag-line
With the defect for falling beam, the anti-seismic performance of bridge structure is improved.The technology employed by the present utility model is include bridge pier and
The beam body being disposed thereon successively has bearing pad stone and rubber support, in bridge pier and beam from bottom to top between bridge pier and beam body
Also tensioning has drag-line between body, is additionally provided with damping device among the bridge pier and beam body.
Described drag-line one end passes through spherical interconnecting piece and connect with beam body, is additionally provided in the beam body sliding for spherical interconnecting piece
Dynamic steel guide groove, the level with reserved steel beam hole that the drag-line other end passes through spherical bellend and is arranged on bridge pier are pre-
Bury steel plate connection.
The steel guide groove is welded in beam body by pre-embedded steel slab.
The spherical interconnecting piece of the drag-line and spherical bellend are the claim-reduction using spherical steel sleeve compression moulding.
The damping device includes that the use ultra-tough fiber concrete UTFC being arranged in above bridge pier and below beam body is poured
The longitudinal block built, the longitudinal direction block adjacent surface are provided with damping cushion.
The beneficial effects of the utility model are:
Due to being provided with damping device and drag-line, when bridge is acted on by small earthquakes, limited by damping device
Beam body processed generates excessive displacement damping and consumes energy and prevent adjacent two beam body from hard collision occurs.When bridge is acted on by big shake
When, drag-line plays a role, and can limit the excessive displacement amplitude of beam body vertical and horizontal simultaneously, and the generation of restrainer earthquake mentions
High bridge entirety anti-seismic performance is horizontal, prolongs the service life.
Since longitudinal block is poured using ultra-tough fiber concrete UTFC, have the effect of it is more safe and reliable, and
The design requirement of different earthquake resistant engineerings can be met by adjusting the proportion of ultra-tough fiber concrete UTFC and the beam number of drag-line.
