Description
[technical field]
The utility model relates to the technical field of road and bridge, particularly the technical field of the crashproof damping bridge of a kind of parallel connection.
[background technology]
Bridge earthquake resistance glissando is to realize by increasing the method for the Rigidity and strength of bridge pier substantially at present, the methods such as shock isolating pedestal or damper that arrange between bridge and bridge pier realize, but for high pier bridge, because bridge pier lateral rigidity is less, bridge pier and its bridge supporting form a kind of flexible structure, the effect that adopts said method to reduce earthquake does not have positive effect, in Modern Traffic simultaneously, for meeting the needs of opposing traffic, most bridges are parallel bidirectional bridge, bridge in two current directions of difference is independent each other, between them, by partitioning slot, separate, when there is earthquake, also easily cause the two-part bridge in left and right along laterally producing hard collision, two bridges can not rely on mutually simultaneously, the active force that common one or two bridge pier ground of reply produces while being subject to earthquake effect, particularly for the larger high pier bridge of flexibility, the most common along horizontal mutual impact wreckage during earthquake.In Bridge bottom, city, often having highway passes through, traditional mode is, at bridge pier, crash bearer is set around, its effect is to prevent the damage of errant vehicle to bridge, but due to existing crash bearer almost without any impact mitigation measure, after on car hit, tend to automobile to cause serious damage, passenger's life security can not effectively be protected.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly; the crashproof damping bridge of a kind of parallel connection is proposed; when geological process; can make two bridge pier tops flexible dependence mutually; avoid producing hard collision, can be good at protecting bridge, increase the shock resistance of bridge pier; can effectively protect the shock of errant vehicle to bridge pier, and can protect preferably passenger's life security simultaneously.
For achieving the above object, the utility model proposes the crashproof damping bridge of a kind of parallel connection, comprise bridge pier, bearing platform, guided way, clash into guide seat, buffer board, pier shaft, bridge and damper, on described bridge pier, be provided with bearing platform, described bearing platform top is provided with pier shaft, on described pier shaft, be provided with pier cap, on described pier cap, bridge is installed, between described bridge and bridge, be provided with damper, pier shaft sidepiece is provided with guided way, the connecting line direction of the length direction of described guided way and two pier shafts intersects, on described guided way, be provided with shock guide seat, guided way end is provided with buffer board.
As preferably, described bearing platform is parallel with horizontal plane, and the thickness of bearing platform is 500～2000mm.
As preferably, described guided way bottom is provided with fixed base plate, on described fixed base plate, is provided with fixing hole, on described fixing hole, staple is installed, and the length of described staple is 300～1000mm.
As preferably, described guided way top is provided with upper rail plate, described upper rail plate with clash into guide seat and coordinate installation.
As preferably, between described bridge and bridge, be provided with spring.
As preferably, between described pier cap and pier cap, be provided with damper.
The beneficial effects of the utility model: the utility model is by being applied in damper on the top of bridge pier; the hard collision of adjacent bridge while can be good at preventing earthquake; can make two bridge flexible contacts; can jointly tackle the active force of earthquake; shock resistance is stronger, shock guide seat and buffer board is applied in bridge facility simultaneously, can effectively prevent the impact damage of errant vehicle to bridge pier; and can make vehicle deceleration by cushioning effect, can protect preferably the safety of passengers in vehicle.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
