Abstract
The present invention relates to a road guardrail made of composite materials, which comprises an upright post (1) and a waveform guardrail plate (7). The present invention is characterized in that an energy-absorption buffer is connected between the upright post (1) and the waveform guardrail plate (7); the energy-absorption buffer comprises an anchor ear (2), waveform energy-absorption buffer plates (4), a shaped connecting plate (5), connecting plates (6) of a waveform guardrail and a fastening piece (3), wherein the anchor ear (2) is anchored on the upright post (1); the two waveform energy-absorption buffer plates (4) are transversally and parallelly arranged between the shaped connecting plate (5) and the anchor ear (2) on the upright post (1); the two connecting plates (6) of a waveform guardrail are leftwards and rightwards arranged between the shaped connecting plate (5) and the waveform guardrail plate (7) in the longitudinal direction. When the road guardrail receives the action of external force, the guardrail plate, the energy-absorption buffer and the upright post absorb the energy of the external force simultaneously and deform, impact force is released, rebound is reduced to be minimum, and the guardrail plate, the energy-absorption buffer and the upright post freely recover after the impact force passes. Thus, the road guardrail can perform the function of protecting transportation tools and personal safety.
Description
Technical field:
The present invention relates to a kind of highway barrier, especially relate to a kind of highway protecting fence made of composite material.Belong on the highway and go along with sb. to guard him the facility technology field.
Background technology:
Before the present invention makes, go along with sb. to guard him facility on the existing highway and form by column and guardrail, be arranged on the both sides of highway, in case automobile is gone out highway pavement and traffic accident is taken place.The part of column is imbedded underground, and another part is installed the protection guardrail on the ground on the column.This guardrail processes corrugated guardrail by general steel plate.Structure in the past also comprises wave beams layer structure, the outer system formula device of bow etc.Because the restriction of structure and material, this kind gone along with sb. to guard him facility and do not absorb energy when vehicle impact.Automobile is impaired when collision easily, and washes out guardrail, and the traffic safety accident takes place easily; Exist corrosion serious simultaneously, the maintenance work amount is big, problems such as expense height.
Technology in the past also comprises the even matter densified composite guardrail that adopts glass-reinforced plastic material or be made up of base-material and muscle material, though it has overcome the shortcoming of steel, and poor toughness, and can not recycle, can cause environment pollution.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of highway protecting fence made of composite material with the effect that absorbs impact load is provided.
The object of the present invention is achieved like this: a kind of highway protecting fence made of composite material, comprise column and corrugated guardrail board, and be connected energy absorbing buffer between column and the corrugated guardrail board.
Above-mentioned energy absorbing buffer comprises anchor ear, corrugated energy-absorbing buffering plate, formed connected fishplate bar, corrugated guardrail junction plate and securing member, the anchor ear obvolvent is on column, corrugated energy-absorbing buffering plate has two, laterally flat raft is arranged between the anchor ear on formed connected fishplate bar and the column, and two ends are connected with anchor ear with formed connected fishplate bar respectively with securing member; Corrugated guardrail junction plate has two, and vertical the first from left right side is arranged between formed connected fishplate bar and the corrugated guardrail board, and two ends are connected with corrugated guardrail board with formed connected fishplate bar respectively with securing member.
Guardrail is a kind of guardrail that energy-absorbing function is arranged, and the present invention installs snubber between guardrail board and column, further plays cushioning effect.The bottom of the overground part of column is a bellow-shaped, deformable when being subjected to external impacts, and can reply, and the elastic force of replying is very little.At the position that is connected with column is corrugated energy-absorbing buffering plate, and it does the time spent being subjected to external force, and guardrail board, energy absorbing buffer and column absorb the distortion of external force energy simultaneously, makes impact force obtain discharging, and it is minimum that bounce-back is reduced to, and impact force is freely replied again later.Therefore can play the effect of the protection vehicles and personal safety.
Guardrail of the present invention is by making with mica and glass mat enhanced polypropylene composite material, it comprises matrix and glass mat, wherein, the component of matrix comprises: polypropylene 40～87%, mica 10～50%, maleic anhydride inoculated polypropylene 2.5～15%, low-molecular polypropylene wax 0.1～2.5%, more than all be weight percentage; The volume content of matrix and glass mat is in the composite material: matrix 80～95%, glass mat 5～20%.
Compare with glass-reinforced plastic material, guardrail of the present invention has in light weight, the intensity height, and good toughness, characteristics such as excellent corrosion resistance are a kind of reusable environmental protection new materials, its cost and durability have again with original facility and match in excellence or beauty.
