Description
Technical field
The utility model belongs to highway engineering field, the more particularly to technical field of safety protection of highway.
Background technology
With the fast development of highway, the safety problem brought therewith also becomes increasingly conspicuous, and wherein highway lacks
Good guard bar device is one of the main reason for accident occurs, and especially takes a sudden turn section in highway, car crash thing
Therefore it happens occasionally.Currently, generally can all build most of guard bar device, existing guard bar device in highway zig zag section
For concrete guardrail or guardrail wires, they can keep out the impact force of a part of automobile impacting to a certain extent, but due to
Existing guard bar device energy-absorbing effect is poor, and when encountering larger car crass impact, especially bus or heavy long vehicle impact is made
Under, it is more also easy to produce major casualties.
Existing guard bar device, cannot play certain cushioning effect, and absorbability is limited and height is relatively low, at the same be easy by
Damage, rehabilitation cost are big.
Utility model content
The defects of the utility model is for buffering effect existing for existing guard bar device and insufficient energy-absorbing effect, is now designed
A kind of highway zig zag safety barrier, with good energy-absorbing effect and also with guiding role.
The utility model is to solve the above problems, using following technical proposals.
A kind of highway zig zag safety reinforcement guardrail, including the column of multiple spacing side by side setting, the first arc are horizontal
Beam, the second curved cross member and curved panel, the column are just connected on foundation of road bed, and the first curved cross member is arranged at the top of column
And two adjacent upright posts are connected, and height ＞ 1.5m of first curved cross member apart from road surface, the second curved cross member are arranged first
The lower section of curved cross member, and connect two adjacent upright posts, the cancave cambered surface of the first curved cross member and the second curved cross member is towards highway
Side, the first curved cross member, the second curved cross member and two adjacent upright posts constitute curved panel installation space, the curved panel
In curved panel installation space, and the cancave cambered surface of curved panel is towards highway side.
Further, the curved panel is honeycomb al member.
Further, the first curved cross member is connected and fixed with the second curved cross member by bolt and column.
Further, the column, the first curved cross member and the second curved cross member are steel component.
Further, the column suspension column just connects, and larger flecition power can be resisted by just having connect suspension column.
The beneficial effects of the utility model are：The utility model reinforces guardrail using the safety of arcuate structure, and Curved beam exists
Under the car crass impact force action in guardrail direction, end reaction is decomposed into a part of horizontal impact and acts on and generate
Horizontal displacement is effectively reduced perpendicular to the collision impact active force in guardrail direction and displacement, therefore has good cushion performance
And energy-absorbing effect, and the bearing capacity that safety reinforces guardrail can be effectively improved, ensure the agent structure peace of safety barrier
Entirely, the casualties and property loss of major motor vehicle generation is greatly reduced.The utility model is used for the peace of highway zig zag
Full protection.
Description of the drawings
Fig. 1 is the structural schematic diagram that a kind of highway zig zag safety described in the utility model reinforces guardrail.
Fig. 2 is the front view that a kind of highway zig zag safety described in the utility model reinforces guardrail.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations being previously mentioned in text, not singly refer to component and directly connect, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the utility model creation
Feature, can be with combination of interactions under the premise of not conflicting conflict.
Referring to Fig.1~Fig. 2, a kind of highway zig zag safety reinforcement guardrail, including the setting of multiple spacing side by side are stood
Column 1, the first curved cross member 2, the second curved cross member 3 and curved panel 4, the column 1 are just connected on foundation of road bed, the first arc
The setting of crossbeam 2 is at 1 top of column and connects two adjacent upright posts 1, and height ＞ 1.5m of first curved cross member 2 apart from road surface,
Second curved cross member 3 is arranged in the lower section of the first curved cross member 2, and connects two adjacent upright posts 1, the first curved cross member 2 and the
The cancave cambered surface of two curved cross members 3 is towards highway side, the first curved cross member 2, the second curved cross member 3 and two 1 structures of adjacent upright posts
Camber panel installation space, the curved panel 4 is mounted in curved panel installation space, and the cancave cambered surface of curved panel 4
Towards highway side.
Further, the curved panel 4 is honeycomb al member, and honeycomb al member can absorb most of energy, and weight
Gently, intensity is high, simple installation.
Further, the first curved cross member 2 is connected and fixed with the second curved cross member 3 by bolt and column 1, passes through bolt
It is fixed, when vehicle hits guardrail, allow have partial slip at 3 bearing of the first curved cross member 2 and the second curved cross member, release impact
Energy reduces percussion and blastic deformation.
Further, the column 1, the first curved cross member 2 and the second curved cross member 3 are steel component.
Further, the column suspension column just connects, and larger flecition power can be resisted by just having connect suspension column.
The better embodiment of the utility model is illustrated above, but the utility model creation is not limited to
The embodiment, those skilled in the art can also make various etc. without departing from the spirit of the present invention
With modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
