Collison fence for bridge is the important node that anticollision barrier designs completely in the structure at place, shrinkage joint, and guardrail should have enough deformabilities at assigned direction herein, to satisfy the requirement of bridge free-extension distortion, needs again to possess certain anti-collision ability.At present, domestic existing bridge expanssion joint place anticollision barrier generally adopts hinge type guardrail or nested type guardrail.
As shown in Figure 1, the hinge type anticollision barrier has adopted the flexible hinge connection, can adapt to the relative displacement of a plurality of directions between the bridge expanssion joint.Its shortcoming is that the rigidity of hinge significantly is lower than the anti-collision level requirement of guardrail, becomes the most unsafe weak link in full-bridge anticollision barrier system.
As shown in Figure 2, the nested type anticollision barrier has adopted the nested mode of steel pipe to realize the vertical bridge of bridge to flexible demand, and has the stronger rigidity of structure, can satisfy the anti-collision level requirement of guardrail.Its shortcoming is, only can satisfy the malformation requirement of fixing a direction, and when bridge direction of displacement and anticollision barrier column line direction are inconsistent, i.e. during beam-ends generation transversion malposition, this guardrail can't the commensurate structure deformation requirements.And in grand bridge, beam-ends to when distortion, is often followed the direction across bridge distortion at vertical bridge, and to rotate in the beam-ends horizontal plane be a kind of common working condition.
Above-mentioned two kinds of anticollision barrier beam types are difficult to possess simultaneously the crashworthiness requirement of the multidirectional deformation requirement of bridge expanssion joint place and anticollision barrier.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of rigidity multi-directional deflection anticollision barrier is provided, this anticollision barrier is by arranging scalable horizon bar between the column of bridge expanssion joint both sides, these scalable horizon bar two ends are hinged with the column that is positioned at its both sides respectively simultaneously, make this anticollision barrier can adapt to length travel and transversal translation between the bridge beam body to reach.
The object of the invention realizes being finished by following technical scheme:
A kind of rigidity multi-directional deflection anticollision barrier relates to the column that is arranged at the bridge expanssion joint both sides, it is characterized in that between the described column of both sides that along bridge to scalable horizon bar is set, the two ends of described scalable horizon bar are articulated and connected with described column respectively.
Described scalable horizon bar is some to evenly being arranged at intervals with along described upright post vertical, described scalable horizon bar by an interior horizon bar with one outer horizon bar is nested consists of.
One end of described scalable horizon bar is hinged by a bearing pin and described column.
One end of described scalable horizon bar is hinged by a cuff system and described column, described cuff system comprises the circular boop that is arranged on the described column, is sheathed on the rotating shaft in the described circular boop and the rest chassis of supporting described rotating shaft, wherein said circular boop is fixedly connected with described column, and an end of described rotating shaft and described scalable horizon bar is welded and fixed.
Consist of the frame type integrative-structure by vertical connecting rod welding between some described outer horizon bars.
Consist of the frame type integrative-structure by vertical connecting rod welding between some described interior horizon bars.
Advantage of the present invention is, 1. can realize freely changing of relative distance between the fence upright; 2. the longitudinal extension distortion occurs in the mutually nested interior horizon bar and outer horizon bar, and the construction profile of anticollision barrier and crashproof ability are without significant change during distortion; 3. by cuff system and the bearing pin system at scalable horizon bar two ends, can realize relatively rotating and transversal translation between the column of anticollision barrier; 4. connect into after the frame type integrative-structure by vertical connecting rod between the scalable horizon bar, stronger crashproof ability is arranged; 5. material all adopts traditional anticollision barrier to make up, and is easy to buying, and cost is lower; 6. profile and conventional guard rail are unified, neat appearance.
