The utility model purpose 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 vertically evenly is arranged at intervals with some along described column, described scalable horizon bar by horizon bar in one outer horizon bar is nested constitutes.
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 hoop cover system and described column, described hoop cover 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 fixedlyed connected with described column, and the end welding of described rotating shaft and described scalable horizon bar is fixing.
Constitute the frame type integrative-structure by vertical connecting rod welding between some described outer horizon bars.
Constitute the frame type integrative-structure by vertical connecting rod welding between some described interior horizon bars.
The utility model has the advantages that, 1. can realize freely changing of relative distance between the fence upright; 2. the longitudinal extension distortion occurs in mutually nested interior horizon bar and the outer horizon bar, and the construction profile of anticollision barrier and crashproof ability do not have significant change during distortion; 3. by hoop cover 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.
