Specific embodiment
The application solves disadvantage present in existing highway bridge guardrail, provides that a kind of energy-absorbing effect is good, and crashworthiness is strong, tool
There is the good protection for preventing vehicle from going out runway to hit guardrail.To achieve the goals above, this patent provides a kind of novel
Anticollision barrier, as shown in Figs 1-4, including stainless steel steel cylinder column 1, bearing 2,2 outside stainless steel energy absorbing members 3 of bearing are stainless
There is energy-absorbing buffering rubber protecting jacket 4 on the outside of steel energy absorbing members 3.1 lower end of stainless steel steel cylinder column is equipped with round fixed disc pedestal
5。
As shown in Fig. 2, stainless steel energy absorbing members 3 among the different steel cylinder of two diameters with 8 steel discs are circumferential by uniformly dividing
Cloth support connection, 8 support steel disc stress bending deformations absorb load impact energy.
Top, middle part segmented section class rectangle steel pipe connecting between stainless steel steel cylinder column 1 and stainless steel steel cylinder column 1
It connects, holds single guiding, connection guardrail absorbs impact the effect of load jointly.Between section class rectangle steel pipe and section class rectangle steel pipe
Connected with the smaller class rectangle steel pipe socket in section, and bolt is added to fix.Specific 1 top of several stainless steel steel cylinder columns and top class
Rectangular steel pipe 6 is bolted, and middle part and 7 sets of middle part class rectangle steel pipe companies pass through small section between class rectangle steel pipe and steel pipe
Noodles rectangular steel pipe 8 overlaps.
For the evenly distributed arrangement with stainless steel steel cylinder column 1 in the middle part of top class rectangle steel pipe 6 with the through-hole of position, through-hole is straight
Diameter size is slightly larger than the diameter of bolt.In order to which bolt is just inserted into through-hole, Lai Shixian class rectangle steel pipe 6 and stainless steel steel cylinder column
Bolt between 1 connects；
For the evenly distributed arrangement with stainless steel steel cylinder column 1 in the middle part of middle part class rectangle steel pipe 7 with the through-hole of position, through-hole is straight
Diameter size is slightly larger than the diameter of stainless steel steel cylinder column 1.In order to which stainless steel steel cylinder column 1 just protrudes into through-hole, thus real
The connection of existing class rectangle steel pipe 7 and stainless steel steel cylinder column 1.
Wherein single top class rectangle steel pipe 6 and single 7 both ends of middle part class rectangle steel pipe are respectively provided with 4 every the logical of identical size
Hole, clear size of opening are slightly larger than Bolt sizes, position point two rows, and a row two is evenly arranged.
Class rectangle steel pipe 6 and class rectangle steel pipe 7 are different except clear size of opening, other materials, and size etc. is all the same.
8 length about 20cm of small bore class rectangle steel pipe, other are such as material, and shape is identical as class rectangle steel pipe 6, section ruler
It is very little to be slightly less than class rectangle steel pipe 6, in order to fill between two class rectangle steel pipes to be connected.Single small bore class rectangle steel pipe
8 two sides are uniformly arranged two rows of every row four and amount to eight through-holes, and clear size of opening is slightly larger than Bolt sizes and top class rectangle steel pipe 6
With the same size of bolt hole of 7 both ends of middle part class rectangle steel pipe setting, it is connect in order to which bolt is inserted into class rectangle steel pipe 6 and 7.
Outer rubber protective case and stainless steel the energy absorbing members load that is hit deform at many levels, and energy-absorbing effect is good, and load is hit
It hits band dynamic bearing to rotate, changes Vehicular impact angle, can preferably evacuate conduction energy, avoid Impact energy from concentrating, segmented
Steel pipe connection stainless steel steel cylinder column avoids that extensive damage is caused to reduce destruction cost because of local impact and is also accompanied by guide rail
A part guiding changes the effect of projected angle of impact.When Vehicular impact load is smaller, rubber protecting jacket initial absorption energy is simultaneously right
Stainless steel energy absorbing members and stainless steel steel cylinder column provide protection, while hitting band dynamic bearing rotation and changing the change of Vehicular impact angle
Mutually evacuation energy avoids Impact energy from excessively concentrating；When Vehicular impact load is larger, rubber protecting jacket and stainless steel energy-absorbing structure
Part deforms together absorbs energy, while hitting band dynamic bearing rotation and change Vehicular impact angle and in a disguised form evacuating energy and avoid impact energy
Amount is excessively concentrated；When impact load is larger or projected angle of impact near normal, the stainless steel steel cylinder column being impacted be not enough to
Shock resistance, more stainless steel steel of connection section class rectangle steel tube confinement between stainless steel steel cylinder column and stainless steel steel cylinder column
Cylinder column bears impact force jointly prevents vehicle from going out runway.
