Background technology
Collison fence for bridge is the important node of anticollision barrier design completely in the structure at shrinkage joint place, and guardrail should have enough deformabilities in the direction indicated herein, to meet 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, general employing hinge type guardrail or nested type guardrail.
As shown in Figure 1, hinge type anticollision barrier have employed flexible hinge and connects, and can adapt to the relative displacement of multiple directions between bridge expanssion joint.Its shortcoming is, the rigidity of hinge, significantly 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, nested type anticollision barrier have employed the nested mode of steel pipe and achieves bridge and indulge bridge to flexible demand, and has the stronger rigidity of structure, can meet the anti-collision level requirement of guardrail.Its shortcoming is, only can meet the malformation requirement fixing a direction, when bridge displacement direction and anticollision barrier column line direction inconsistent time, namely during beam-ends generation transversion malposition, this guardrail cannot commensurate structure deformation requirements.And in grand bridge, beam-ends is when vertical bridge is to distortion, normal with direction across bridge distortion, and the horizontal rotation in surface of beam-ends is a kind of common working condition.
Above-mentioned two kinds of anticollision barrier beam type are difficult to the crashworthiness requirement simultaneously possessing the multidirectional deformation requirement of bridge expanssion joint place and anticollision barrier.
Summary of the invention
The object of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of rigid multiway displacement anticollision guardrail is provided, this anticollision barrier 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 being positioned at its both sides respectively simultaneously, make this anticollision barrier can adapt to length travel between bridge beam body and transversal translation to reach.
The object of the invention realizes being completed by following technical scheme:
A kind of rigid multiway displacement anticollision guardrail, relates to the column being arranged at bridge expanssion joint both sides, between the described column that it is characterized in that both sides along bridge to arranging scalable horizon bar, the two ends of described scalable horizon bar are articulated and connected with described column respectively.
Described scalable horizon bar is provided with some along described upright post vertical to uniform intervals, described scalable horizon bar is formed by horizon bar is nested with an outer horizon bar in one.
One end of described scalable horizon bar by a bearing pin and described column hinged.
One end of described scalable horizon bar by a cuff system and described column hinged, described cuff system comprises the circular boop be arranged on described column, is sheathed on the rotating shaft in described circular boop and supports the rest chassis of described rotating shaft, wherein said circular boop is fixedly connected with described column, and one end of described rotating shaft and described scalable horizon bar is welded and fixed.
Frame type integrative-structure is formed by vertical connecting rod welding between some described outer horizon bars.
Frame type integrative-structure is formed 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 fence upright; 2. longitudinal extension distortion occurs in mutually nested interior horizon bar and outer horizon bar, and during distortion, the construction profile of anticollision barrier and crashproof ability are without significant change; 3. by cuff system and the pin roll system at scalable horizon bar two ends, relatively rotating and transversal translation between the column that can realize anticollision barrier; 4., after connecting into frame type integrative-structure by vertical connecting rod between scalable horizon bar, stronger crashproof ability is had; 5. material all adopts conventional crash guardrail to build, and be easy to buying, cost is lower; 6. profile and conventional guard rail unification, neat appearance.
