Abstract

The utility model discloses a PVC energy absorption protective guard for roads, the body of the protective guard is a saddle-shaped hollow casing, the inner surface layer of the casing is uniformly distributed with a plurality of independent decompression chambers, and the middle of the casing is equipped with a supporting framework. The body of the protective guard utilizes the structure of the decompression chambers and the supporting framework, which enlarges the energy absorption capacity of the protective guard. When vehicles crush to the protective guard, the protective guard can sufficiently absorb the impact force, thereby reducing the incidence rate of lethality heavy accidents. The protective guard is made of PVC materials, which can be regenerated and reused, thereby saving energy without polluting the environment. PVC has unique elasticity and enlarges cushioning coefficient, which is more beautiful. Further, the PVC energy absorption protective guard for roads solves the problem that the conventional steel protective guard is easy to rust and lose, and is not easy to maintain.

Description

Highway PVC energy-absorbing protective guard
Technical field:
The utility model is to the improvement of existing highway with the protective guard structure, has further provided a kind of highway with PVC energy-absorbing protective guard, belongs to highway safety facility technology field.
Background technology:
The protective guard effect that is provided with on the highway is to prevent that derailment from falling into steep cliff, existing iron protective guard is simple hollow shell structure, and when bumping, the guardrail energy absorption capacity is very poor, the effect of security protection can not be well played, the lethal weapon of anti-personnel may be become sometimes.Particularly when the more weak iron plate vehicle of strength ratio bumps against protective guard, human body is easy to cause fatal harm, greatly reduces the security protection performance of protective guard.
Summary of the invention
The utility model discloses a kind of highway with PVC energy-absorbing protective guard, has solved the low shortcoming of existing guardrail safety factor.
Technical solution of the present utility model is as follows: the protective guard body is the hollow shell of horse-saddle, the endosexine of housing some pressure-releasing chambers independently mutually that evenly distribute, and the centre of housing is provided with support frame.
The protective guard that the utility model adopts the PVC material to form utilizes PVC to have unique elasticity.Simultaneously can add the Chang Yuhui particular matter in protective guard, need not voltage can be luminous voluntarily, also can very easily tell protective guard at nighttime driving.
Good effect of the present utility model is: the protective guard body adopts pressure-releasing chamber and support frame structure, increase protective guard and got energy absorption capacity, when vehicle bumps with it, can absorb the impact force that is produced fully, thereby reduce the generation of mortality major accident.Cushioning coefficient strengthens, and is more attractive in appearance; Utilization PVC material, reproducible utilization, energy conservation and free from environmental pollution; Can self-luminous, solved the problem that traditional steel protective guard reflecting marking is easily lost; Anti-aging, maintenance is convenient, has solved traditional steel protective guard and has easily got rusty, and is difficult for the problem of maintenance.
Description of drawings
Fig. 1 is the utility model structure principle chart.
The specific embodiment
According to shown in Figure 1, the protective guard body that adopts the PVC engineering plastics to make is the hollow shell 1 of annular saddle, the endosexine of housing 1 some pressure-releasing chambers 2 independently mutually that evenly distribute, pressure-releasing chamber 2 is an oblong-shaped, the centre of housing 1 is provided with support frame 3, and support frame 3 is zigzag and is distributed on the sidewall of pressure-releasing chamber 2.

Claims (1)

1. a highway is with PVC energy-absorbing protective guard, and it is characterized in that: the protective guard body is the hollow shell of horse-saddle, the endosexine of housing some pressure-releasing chambers independently mutually that evenly distribute, and the centre of housing is provided with support frame.
