Description
Technical field
Road guard technical field is the utility model is related to, more particularly to a kind of tunnel multi-buffer guardrail.
Background technology
As the improvement of people's living standards, the vehicle travelled on road is also more and more, but when traveling is in tunnel
When, due to dark in tunnel and road is narrower, often results in an automobile accident or the generation of collision accident, and present tunnel
The middle rigidity that usually steel plate punched forms used does not have the guardrail of cushioning effect, or the plastics system by simple structure
Into when vehicle causes danger collision when on such guardrail, due to the effect very little of guardrail buffering, vehicle can be hit at a high speed
The reaction force brought is hit, therefore the personnel of vehicle and in-car can be by life danger.
The content of the invention
In order to solve the problems, such as tunnel guardrail buffering effect difference, the utility model provides a kind of tunnel multi-buffer shield
Column, the technical scheme of use are as follows：
A kind of tunnel multi-buffer guardrail, including several columns, the cross bar that is connected between two adjacent upright posts, its feature
It is, in addition to quantity corresponds with column and is fixed on the U-shaped that cross section in the horizontal direction of column upper outside is U-shaped
Bolster and a cross section in horizontal direction being fixed on the outside of U-shaped bolster are inverted U-shaped inverted U-shaped bolster,
Described U-shaped bolster is by U-shaped bolster mainboard and the U-shaped bolster being connected at left and right sides of U-shaped bolster mainboard
Outside plate and U-shaped bolster inner panel composition, the inverted U-shaped bolster is by inverted U-shaped bolster mainboard and is connected to inverted U-shaped slow
Inverted U-shaped bolster outside plate and inverted U-shaped bolster inner panel composition at left and right sides of stamping mainboard, the U-shaped bolster inner panel is with standing
Post upper outside is fixed, and U-shaped bolster outside plate is fixed with inverted U-shaped bolster inner panel.
Described U-shaped bolster and inverted U-shaped bolster are made by galvanized steel plain sheet, and the thickness of U-shaped bolster is 2 ~ 3mm,
The thickness of inverted U-shaped bolster is 1 ~ 1.5mm.
The distance between described U-shaped bolster inner panel and U bolster outside plates are 50 ~ 100mm, in inverted U-shaped bolster
The distance between plate and inverted U-shaped bolster outside plate are 80 ~ 120mm.
The bottom of described inverted U-shaped bolster outside plate and the distance of column bottom in the vertical direction are 0 ~ 150mm.
The beneficial effects of the utility model are：The U-shaped opening direction of U-shaped bolster is consistent with the travel direction of vehicle,
When Vehicular impact guardrail, kinetic energy when it hits can be decomposed into horizontal direction perpendicular to guardrail and parallel to guardrail two
Direction, U-shaped bolster and inverted U-shaped bolster can be shunk by the elasticity of itself, so as to being vertical perpendicular to cross bar
In the energy on inverted U-shaped bolster outside plate direction enter row buffering, while U-shaped bolster can be by itself in the horizontal direction
Stretching etc. parallel to the energy on cross bar direction come to entering row buffering, by entering row buffering to automobile impacting in the two directions,
Phenomena such as casualties and vehicle damage can be effectively reduced.
It is inverted U-shaped slow when faint shock occurs for vehicle and the thickness and width of inverted U-shaped bolster are low compared with U-shaped bolster
Stamping can be used as first of alignment buffer, when Vehicular impact dynamics is very big, and then continue to buffer by U-shaped bolster, can
To reduce the abrasion of parts.
Brief description of the drawings
Fig. 1 is the structural representation of tunnel multi-buffer guardrail
Wherein 1- columns, 2- cross bars, 3-U shape bolster inner panels, 4-U shape bolster mainboards, 5-U shape bolster outside plates,
The inverted U-shaped bolster inner panels of 6-, the inverted U-shaped bolster mainboards of 7-, the inverted U-shaped bolster outside plates of 8-.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
Tunnel multi-buffer guardrail as shown in Figure 1, it is one-to-one by several columns 1, cross bar 2, quantity and column 1
U-shaped bolster, an inverted U-shaped bolster composition, the bottom of column 1 fix on the ground, pass through horizontal stroke between adjacent two root posts 1
Bar 2 is connected, and wherein U-shaped bolster by U-shaped bolster mainboard 4 and is connected to U-shaped at left and right sides of U-shaped bolster mainboard
Bolster outside plate 5 and U-shaped bolster inner panel 3 form, and inverted U bolster is inverted U-shaped in the cross section in horizontal direction
And by inverted U-shaped bolster mainboard and the inverted U-shaped bolster outside plate being connected at left and right sides of inverted U-shaped bolster mainboard and
Inverted U-shaped bolster inner panel composition, U-shaped bolster inner panel are connected by screw the upper outside for being fixed on column 1, U-shaped bolster
Outside plate is connected by screw to be fixed with inverted U-shaped bolster inner panel, and the side that the U-shaped opening direction of U-shaped bolster is advanced with vehicle
To consistent.
In the present embodiment, U-shaped bolster is made with both inverted U-shaped bolsters by galvanized steel plain sheet, the thickness of U-shaped bolster
Spend for 3mm, the thickness of the property of falling U bolster is 1.5mm, and the distance between U-shaped bolster inner panel 3 and U-shaped bolster outside plate 5 are
100mm, the distance between inverted U-shaped bolster inner panel 6 and inverted U-shaped bolster outside plate 8 are 70mm, U-shaped bolster and inverted U-shaped slow
Stamping, which is shaped such that, itself has certain elasticity and pull resistance, and the inverted U-shaped bottom of bolster outside plate 8 is with the bottom of column 1 perpendicular
The upward distance of Nogata is 100mm, it can be ensured that automobile can be contacted with the outside plate of inverted U-shaped bolster so as to slow during Vehicular impact
Rush portion of energy.
In general Vehicular impact is the shock of horizontal direction, and shock in the horizontal direction can be decomposed into parallel to tunnel
Multi-buffer rail horizontal rod 2 is with perpendicular to the both direction of cross bar 2, the tunnel multi-buffer guardrail described in the present embodiment, working as vehicle
When hitting guardrail, U-shaped bolster and inverted U-shaped bolster are deformed by itself by external force, so as to perpendicular to rail horizontal rod
2 energy i.e. on inverted U-shaped bolster outside plate direction enters row buffering, while U-shaped bolster can be by the horizontal direction
On stretching come to entering row buffering parallel to the energy on the direction of cross bar 2, by delaying in the two directions to automobile impacting
Punching, phenomena such as casualties and vehicle damage can be effectively reduced.
The thickness of inverted U-shaped bolster and width are low compared with U-shaped bolster simultaneously, inverted U-shaped slow when faint shock occurs for vehicle
Stamping can be used as first of alignment buffer, when Vehicular impact dynamics is very big, and then continues to serve as second by U-shaped bolster and delay
Breast the tape, can so reduce the abrasion of parts.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：The shape of above-mentioned two bolster is not
U-shaped or inverted U-shaped is limited only to, for those skilled in the art, is not departing from the utility model original
On the premise of reason, some improvement and equivalent substitution can also be made, these also should be regarded as the scope of protection of the utility model.
