Abstract
The utility model belongs to bridge beam body technical field, in particular relates to a kind of bridge-collision-avoidance positive stop.Its technical scheme is by the stop body that can be fixed with bridge beam body or bridge pier and is arranged at the stop body and is formed with the corresponding buffering sheet material contacted on side of bridge pier or bridge beam body；The joint face of above-mentioned buffering sheet material is fixed in the stop body, its making contact face is convex configuration.The bridge-collision-avoidance positive stop of the structure with downthrust uniform force, can effectively overcome buffering sheet material and bridge beam body occur linear contact lay or put contact the generation for causing its damaged phenomenon, with service life it is long the characteristics of.
Description
Technical field
It the utility model is related to a kind of bridge beam body technical field, more particularly to a kind of bridge-collision-avoidance positive stop.
Background technology
Bridge-collision-avoidance is spacing to be used to preventing bridge main beam from from bridge pier or Abutment departing from, causes that girder is hanging, fractures or falls
Fall the generation of phenomenon, positive stop is set with the generation of restrainer accident in beam body or pier.At present, used limiting block
Block is by the stop body that can be fixed with bridge beam body or bridge pier and is arranged at that the stop body is corresponding with bridge pier or bridge beam body to be connect
The buffering sheet material touched on side is formed.And because the structure for forming buffering sheet material is cube structure, its making contact formed
Face is planar structure；Regardless of whether when being the error installed or needing beam body with pier in the presence of the oblique angle set, cube
The buffering sheet material of structure cannot realize the uniform stressed in making contact face so that buffering sheet material and bridge can occur linear contact lay or
Point contact so that its local pressure is excessive；Long term can cause to buffer the damage of sheet material and influence whole anticollision positive stop
Service life.
Utility model content
The purpose of this utility model is just to provide a kind of uniform force, can effectively overcome buffering sheet material and bridge beam body to send out
Raw linear contact lay or point contact and cause its bridge-collision-avoidance positive stop impaired, with service life length.
The technical scheme for realizing the utility model above-mentioned purpose is：
A kind of bridge-collision-avoidance positive stop, by the stop body that can be fixed with bridge beam body or bridge pier and it is arranged at the gear
Block is formed with the corresponding buffering sheet material contacted on side of bridge pier or bridge beam body；It is characterized in that：The company of the buffering sheet material
Junction is fixed in the stop body, its making contact face is convex configuration.
Forming a kind of additional technical feature of above-mentioned bridge-collision-avoidance positive stop also includes：
--- described convex configuration is spherical surface hill structure；
--- described convex configuration is horizontal direction arcuate structure；
--- stage clip mechanism is provided with described convex configuration；
--- described stop body is the triangular structure or square being spliced by horizontal steel plate, vertical steel plate, gusset
Structure.
A kind of bridge-collision-avoidance positive stop provided by the utility model compared with the existing technology has advantages below：Due to
The buffering sheet material for forming the positive stop is convex configuration, can bear to collide at any angle when colliding with bridge,
Ensure buffering sheet material uniform force, avoid local pressure, while convex configuration, it is ensured that damping force is continuous in collision process
Increase, can effectively play cushioning effect, can effectively improve the service life of the bridge-collision-avoidance positive stop.

Embodiment
The structure to a kind of bridge-collision-avoidance positive stop provided by the utility model and install and use below in conjunction with the accompanying drawings
It is described in further detail.
As shown in Figure 1, it is a kind of structural representation of bridge-collision-avoidance positive stop provided by the utility model, forming should
The structure of anticollision positive stop is made up of stop body 1 and the bump rubber 2 being fixed on the block body side surface；I.e. such as Fig. 3 institutes
Show that the stop body 1 for forming the anticollision positive stop is fixed by bolt 3 and bridge beam body 4, yielding rubber on its block body side surface
The making contact face 21 of block 2 is convex configuration, the making contact face 21 with（Bridge pier 6 or）The holder base plate 7 being fixed on bridge pier
It is corresponding.I.e. when bridge beam body 4 produces displacement, form the collision that bump rubber 2 protrudes on the anticollision positive stop side and connect
Contacting surface can produce downthrust with the side of holder base plate, because the making contact face of bump rubber 2 is convex configuration, with bridge
Beam can bear to collide at any angle when colliding, and ensure buffering sheet material uniform force, avoid local pressure, while convex surface
Structure can ensure that damping force is continuously increased in collision process, can effectively play cushioning effect.
In a kind of above-mentioned structure of bridge-collision-avoidance positive stop is formed：
--- the convex configuration for forming the making contact face of bump rubber 2 can be the knot of spherical surface hill 211 as shown in Figure 1
Structure, can bear to collide at any angle when colliding with bridge, ensure buffering sheet material uniform force, avoid it is local by
Power；
--- the convex configuration for forming the making contact face of bump rubber 2 can also be horizontal direction arc as shown in Figure 2
The structure of shape 212, the structure of horizontal direction arc 212 can effectively realize beam body in the horizontal direction with（Bridge pier 6 or）It is fixed on bridge
It is equally loaded during extrusion and collision between the holder base plate 7 on pier；
--- as shown in figure 5, in order to further improve the crashworthiness of bridge-collision-avoidance positive stop, forming, anticollision is spacing
Stage clip mechanism 8 is provided with convex configuration in the bump rubber 2 of block；
--- the structure for forming the stop body 1 of bridge-collision-avoidance positive stop both can be by horizontal steel plate, vertical steel plate, muscle
Triangular structure as shown in Figure 1,3 that plate is spliced or as shown in Figure 4 can be with bridge pier（Or branch seat cushion
Plate 7）Fixed square structure.
