Abstract
The invention discloses a kind of energy-absorbing height-limiting frame, including two columns and limit for height crossbeam, described two columns are located at the both sides on road surface respectively, across limit for height crossbeam at the top of column, it is characterized in that, the column and limit for height crossbeam periphery are provided with cushion, and the cushion parcel column and limit for height crossbeam periphery, the limit for height crossbeam use loose structure component.Heretofore described height-limiting frame sets up cushion also can preferably apparatus with shock absorbing, therefore height-limiting frame of the present invention can effectively improve height-limiting frame anticollision ability, the safety of guarantee height-limiting frame agent structure.The present invention is applied to road and bridge tunnel limit for height.
Description
Technical field
The invention belongs to road and bridge tunnel technical field, more particularly to a kind of energy-absorbing height-limiting frame.
Background technology
Growing with transportation, large-scale load-carrying vehicle is more and more, in order to protect highway road, foundation
Road mass of foundation and running situation, vehicle height-limiting frame is often provided with highway.Current existing vehicle limit for height mainly uses
Two root posts and it is connected to piece this structure of crossbeam of column top.Most of existing vehicle height-limiting frames are all to use ordinary steel
Structure is made.The rigidity of steel construction is very big, the crossbeam of automobile impacting height-limiting frame, and the energy of impact can not preferably absorb, often
Cause major traffic accidents, personnel occur and property loss is huge.
The content of the invention
The present invention provides a kind of energy-absorbing height-limiting frame, and the height-limiting frame is provided with cushion in the periphery of column and limit for height crossbeam,
And limit for height crossbeam uses loose structure.For material with loose structure with high strength and stiffness, energy-absorbing effect is good, can reduce
Cost, it is economical and practical.And set up cushion also can preferably apparatus with shock absorbing, therefore height-limiting frame of the present invention can be effective
Ground improves height-limiting frame anticollision ability, ensures the safety of height-limiting frame agent structure.
The present invention is to solve the above problems, using following technical proposals.
A kind of energy-absorbing height-limiting frame, including two columns and limit for height crossbeam, described two columns are located at the both sides on road surface respectively,
At the top of column cushion, the cushion parcel column and limit are provided with across limit for height crossbeam, the column and limit for height crossbeam periphery
High crossbeam periphery, the limit for height crossbeam use loose structure component.
Further, the cushion is foam structure.
Further, the pore structure of the loose structure component is the two dimension knot that hexagonal hole assembles formation in the plane
Structure.
Further, the pore structure of the loose structure component is the two-dimensional structure that square opening assembles formation in the plane.
Further, the two dimension knot that the pore structure of the loose structure component is formed for tri-angle-holed aggregation in the plane
Structure.
Beneficial effects of the present invention are：The height-limiting frame is provided with cushion, and limit for height in the periphery of column and limit for height crossbeam
Crossbeam uses loose structure.The material of loose structure has high intensity, and energy-absorbing effect is good and reduces cost, economical and practical to increase simultaneously
If cushion also can preferably apparatus with shock absorbing, therefore height-limiting frame of the present invention can effectively improve height-limiting frame anticollision energy
Power, ensure the safety of height-limiting frame agent structure.The present invention is applied to road limit for height.
