Abstract
The utility model relates to a bridge protection device, in particular to a bridge crash barrier which can effectively reduce damage on vehicles and barriers in the process of crash, and has good buffer performance. The bridge crash barrier comprises a plurality of supporting columns and a plurality of bases. Each supporting column is composed of a stand column and an inclined column, the upper end of the stand column and the lower end of the inclined column are welded into a whole, and an included angle alpha between the stand column and the inclined column is 160-170degrees. The supporting columns are arranged side by side at equal intervals, the upper ends and the lower ends of the two adjacent inclined columns are welded with upper cross beams and lower cross beams, a connecting plate is welded on the lower surface of each stand column and is fixed on the upper surface of each base through a bolt, embedded type bolt assemblies are arranged on the lower surfaces of the bases, a nylon rope woven mesh is fixed in a region among the upper cross beams, the lower cross beams and two supporting columns, and the inner surface of the nylon rope woven mesh is fixedly connected with an elastic rubber plate. The bridge protection device is used for bridge protection, and capable of greatly absorbing automobile impact force and effectively reducing the damage on the vehicles and the barriers.
Description
Technical field
The utility model relates to a kind of bridge protector, is specifically related to a kind of Collison fence for bridge.
Background technology
Existing Bridge guardrail, in order to prevent that vehicle from turning over bridge, usually adopt the steel bar concrete anticollision barrier, when vehicle unexpected situation occurs and strikes anticollision barrier, owing to be rigid collision, the equal well damage of vehicle and anticollision barrier, after collision frequency is many, also the anticollision barrier concrete spalling can be caused, maintenance and reinforcement need be carried out, not only lose time and manpower the cost of also stepping up its investment simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of Collison fence for bridge, the harm that vehicle and guardrail are subjected in the time of can effectively reducing bump, and have shock-absorbing capacity preferably.
Realize above-mentioned purpose, the technical scheme that the utility model is taked is:
Collison fence for bridge, comprise several support columns and several bases, each support column is made of column and tilt column, the upper end of column and the lower end of tilt column are welded as a whole, angle α=160 ~ 170 between column and the tilt column °, several support columns equidistantly are set up in parallel, upper end between adjacent two tilt columns is welded with top rail, lower end between adjacent two tilt columns is welded with lower transverse beam, each column soffit is welded with junction plate, junction plate is by the upper surface of bolt in base, the soffit of base is equipped with the pre-buried type bolt assembly, top rail, fixedly there is the nylon rope mesh grid in zone between lower transverse beam and two support columns, and inner surface and the elastic rubber slab of nylon rope mesh grid are connected.
As preferably, described top rail and lower transverse beam external surface are equipped with fluorescence coating, and base and support column external surface are equipped with anticorrosive coat.
As preferably, the inner surface of described nylon rope mesh grid is connected by several bolt connection assemblies and elastic rubber slab.
As preferably, the inner surface of described nylon rope mesh grid is connected by bonding mode and elastic rubber slab.
As preferably, described elastic rubber slab is several strip elastic rubber slabs, several strip elastic rubber slab horizontally sets.
The utility model with respect to the beneficial effect of prior art is:
The utility model is because fixedly there is the nylon rope mesh grid in the zone between top rail, lower transverse beam and two support columns, its good buffer effect, inner surface in the nylon rope mesh grid is fixed with elastic rubber slab, has the anti-function of colliding preferably, when running into bump, because the elastic deformation of nylon rope mesh grid and elastic rubber slab can absorb the automobile impulsive contact force greatly, effectively reduces the harm that automobile and guardrail are subjected to.
