Abstract
The utility model relates to a composite material highway guard rail, which comprises a vertical post (1) and a corrugation-shaped guard rail plate (7). The utility model is characterized in that an energy absorption buffer is connected between the vertical post (1) and the corrugation-shaped guard rail plate (7), the energy absorption buffer comprises an anchor ear (2), corrugation-shaped energy absorption buffer plates (4), a shaped connecting plate (5), corrugation-shaped guard rail connecting plates (6) and a fastener (3), wherein the anchor ear (2) is surrounded and closed on the vertical post (1), the utility model is provided with two corrugation-shaped energy absorption buffer plates (4) which are transversely arranged between the shaped connecting plate (5) and the anchor ear (2) on the vertical post (1) in a flat row form, and the utility model is provided with two corrugation-shaped guard rail connecting plates (6) which are longitudinally arranged between the shaped connecting plate (5) and the corrugation-shaped guard rail plate (7) from left to right. The guard rail plate, the energy absorption buffer and the vertical post can simultaneously absorb external force energy to be deformed when are acted by the external force, the impact force can be released, the rebound is reduced to the minimum and the utility model is freely restored after the impact force is finished. Therefore, the functions of vehicle and personal safety protection can be performed.
Description
Technical field:
The utility model relates to a kind of highway barrier, especially relates 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 utility model is made, 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 purpose of this utility model is to overcome above-mentioned deficiency, and a kind of highway protecting fence made of composite material with the effect that absorbs impact load is provided.
The purpose of this utility model is achieved in that a kind of highway protecting fence made of composite material, comprises column and corrugated guardrail board, is 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.
Description of drawings:
Fig. 1 is an outward appearance vertical view of the present utility model.
The A-A partial cutaway diagrammatic sketch of Fig. 1 of Fig. 2.
Fig. 3 is a column sectional drawing of the present utility model.
The specific embodiment:
Referring to Fig. 1～2, the utility model is a kind of glass fiber reinforced thermoplastics composite highway barrier, and it mainly is made up of column 1, annular anchor ear 2, metal fastenings 3, energy-absorbing buffering plate 4, formed connected fishplate bar 5, corrugated guardrail junction plate 6 and corrugated guardrail board 7 etc.Annular anchor ear 2, metal fastenings 3, energy-absorbing buffering plate 4, formed connected fishplate bar 5 and corrugated guardrail junction plate 6 are formed energy absorbing buffer.
Referring to Fig. 3, column 1 is a hollow tubular, and column 1 hypomere is imbedded ground and fixed, and the bottom of column 1 overground part is the hollow corrugated tube shape.
