Abstract
The utility model relates to an impact absorbing structure of a guardrail. The technical problem solved by the utility model is that the utility model can provide an impact absorbing structure of a guardrail which has the advantages of simple and convenient assmembly and disassembly, good buffering effect, beautiful appearance, strong practicality, low cost, and high assurance coefficient. The scheme to solve the problem is that the impact absorbing structure of a guardrail comprises supporting columns which are arranged vertically and alternately, and a protecting rail which is in sliver shape and formed into deck shape with defined spacing. The utility model is characterized in that an energy absorbing tube, which is a hollow tube with unclosed upper opening and lower opening, is arranged to separate the supporting columns from the protecting rail; the side wall clinging to one side of the supporting column and the supporting column are fixed and connected by a metal piece connected with a rod, and the side wall clinging to the side of the protecting rail is fixed by a metal fastener. The utility model can be used for wire poles, signal masts, guardrails of the road side or a central isolation belt, or rails of bridges, toll stations of highways, car parks, etc.
Description
Technical field
The utility model belongs to the absorption impact structure body of fixing road equipment, particularly a kind of guardrail.Be applicable to the ground such as railing, freeway toll station, parking lot of electric pole, guardrail or bridge.
Background technology
In order to prevent steering wheel error and to fly out the track to the sidewalk or motorway in opposite directions with the vehicle that the bump of other vehicles causes, usually crashproof setting is set in the both sides of highway or the centre of highway, but development along with society, automobile is more and more, simultaneously, high-grade highway and Freeway Development, hypervelocity, the overload problems of vehicles peccancy are on the rise, and the defective of traditional crash barrier equipment day by day comes out then.
See also Fig. 1,2, in the prior art, the guardrail 2 of strip ' and the pillar 1 set up of at interval perpendicular row shape ' between by intermediate spacer 3 ' be connected and fixed, its objective is think further to shorten guardrail 2 ' with pillar 1 ' the interval and improve the guardrail integral intensity, the energy of bump car mainly by pillar 1 ' distortion absorb.But the function that pillar itself substantially absorb to impact, under the excessive situation of vehicle impact energy, pillar curved will make the vehicle of bump rush to guardrail or the possibility of breaking through guardrail increases, and the danger that produces 2 disasters also increases.And amplitude is excessive if pillar is curved, and the expansion amplitude in the lane outside of vehicle impact increases, thereby turns back to the difficulty increase of lane with making bump back vehicle safety.Moreover no matter how crooked pillar is repaired becomes straight, always exists potential safety hazard, in this case, is necessary to remove damaged position, excavates foundation again new pillar and guardrail are set.The work trouble of installing and uneconomical.
Summary of the invention
The technical problems to be solved in the utility model is: the impact structure body of the guardrail that a kind of installation is provided, removes simple and convenient, good buffer effect, both artistic and practical low cost and safety factor is high.
The technical scheme that the utility model adopted is: the absorption impact structure body of guardrail; contain the pillar of vertically setting up at interval; strip and form the protection hurdle of crooked deck shape with the interval of regulation; it is characterized in that being separated with between pillar and the protection hurdle energy absorbing tube of the open-ended up and down of hollow tubular; it touch and is connected metalwork by stock between pillar sidewall on one side and the pillar and is connected and fixed, and protects the one side on hurdle to be fixed by metal fastenings touching.
The cross section ovalize of described energy absorbing tube.
It is oblate that the cross section of described energy absorbing tube is.
The cross section of described energy absorbing tube is slightly " Ω " shape.
On the lateral wall of the energy absorbing tube of protecting hurdle one side, be welded with two cantilevers, fixing with metal fastenings between cantilever and the protection hurdle.
On the tube wall of the energy absorbing tube of protecting hurdle one side, directly be connected and fixed with metal fastenings and protection hurdle.
Two planar sections that are the energy absorbing tube that omits " Ω " shape in the cross section are sentenced metal fastenings and are protected the hurdle to be connected and fixed.
It is identical by shape that described cross section is the energy absorbing tube that omits " Ω " shape, and the two superimposed that varies in size together.
The beneficial effects of the utility model are: the absorption impact structure body structure of guardrail of the present utility model is simple, can install easily and remove, according to the irreversible deformation principle of energy absorbing tube, absorb the mitigation Impact energy by distortion, do not collapse thereby pillar is flexible, therefore do not need to excavate foundation as before again and remove crooked pillar, and, when vehicle during with the speed that surpasses imagination and carrying capacity crash hurdle, even pillar self can not absorb impact energy, but the distortion by pillar and collapse and can absorb Impact energy, therefore, can not only prevent that vehicle from breaking through guardrail and the road that flies out outside, can guarantee passenger's personal safety simultaneously.

The specific embodiment
Embodiment 1: shown in Fig. 3,4,5, present embodiment comprises that pillar 1, protection hurdle 2, energy absorbing tube 3, stock connect metalwork 5 and metal fastenings 6.Pillar 1 is made for the surperficial treated steel of hollow tubular, and fluid concrete forms foundation by the road, pillar is imbedded this foundation bottom fix.Protection hurdle 2 is that the steel that the interval with regulation forms crooked first shape and coats rustproof paint is made.This routine energy absorbing tube 3 is the ellipse of hollow tubular, material adopts steel, its material, size, shape etc. all should consider to imagine factors such as the kind, speed, weight of vehicle impact, can suitably change design for obtaining the best buffering effect and the navigation performance of vehicle.Connect 5 pairs of metalworks by stock on corresponding to the sidewall of pillar 1 one sides and pass pillar 1 and be connected and fixed with pillar, the inwall weldering that concrete connected mode is an end and energy absorbing tube is lived, and the other end uses nut fastening; And corresponding to the side on protection hurdle 2, be welded with two cantilevers 4 at the outer wall of energy absorbing tube, it on metal fastenings 6 and protect hurdle 2 to fix.Design sketch after shown in Figure 5 is automobile and pillar bumps against, as we can see from the figure, energy absorbing tube 3 is crushed, and energy absorbing tube can relax bump owing to plastic strain has absorbed the energy of vehicle impact.
Embodiment 2: as shown in Figure 6, this routine structure is basic identical with last example, and difference only is do not have cantilever on the energy absorbing tube 3, and is directly with metal fastenings 6 that energy absorbing tube is fixing with protection hurdle 2.
Embodiment 3: as shown in Figure 7; in this example; difference is that the shape of energy absorbing tube 3 is " Ω " shape; it is fixing with pillar 1 to connect metalwork 5 at the top of its tubular portion by stock, and fixes with protecting hurdle 2 with metal fastenings 6 on the planar section that extends out on the absorption tube both sides.
Embodiment 4: as shown in Figure 8; this example is identical with embodiment 3 basically; its feature is that the energy absorbing tube 3 of " Ω " shape has two; one bigger; one smaller; overlap, the absorption tube that fixes with pillar 1 is bigger one in outside, and it is fixing with protection hurdle 2 that metal fastenings 6 passes the planar extension of two absorption tubes simultaneously.
