Description
Technical field
The present invention relates to bridge technology field more particularly to a kind of safety-type buffer guardrail for bridge.
Background technique
With social progress, national bridge industry is also being rapidly developed, and Bridge guardrail in the market is also all kinds of
It emerges one after another.Bridge guardrail refers to the guardrail being set on bridge.It is traditional its purpose is to prevent vehicle and pedestrian from falling
Although Bridge guardrail plays certain safety, but it does not have preferable resiliency, and vehicle is when occurring emergency episode
It hits that the injury that guardrail is subject to is larger, and has the danger for going out guardrail.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of safety-type bridge buffering proposed
Guardrail.
To achieve the goals above, present invention employs following technical solutions:
A kind of safety-type buffer guardrail for bridge is designed, including the upright post rod being mounted equidistant in bridge two sides, two neighboring institute
It states and is equipped with guardrail board between upright post rod, the upper end of each upright post rod is equipped with the cross bar that one end extends to road surface, described
The upper end two sides of guardrail board are rotatably installed in the one end of cross bar far from upright post rod by shaft, and the lower end two sides of the guardrail board turn
Dynamic to be connected with push rod, the lower end of the two neighboring upright post rod is respectively connected with crossbeam, and the crossbeam is close to the side pair of guardrail board
Title is set there are two limiting slot, and the limiting slot is interior to be equipped with limited block, and the limited block is connected with push rod, the limited block and limit
Spring is equipped between the bottom of position slot.
Preferably, the guardrail board is made of outline border and the wire rope net surface being arranged in outline border.
Preferably, the minimum activity point of view of the guardrail board is 30 degree.
A kind of safety-type buffer guardrail for bridge proposed by the present invention, beneficial effect are: using the guardrail board of activity setting
It is mounted on the pillar of seven fonts, the lower end of guardrail board uses elastic construction, and when vehicle hits guardrail, guardrail board has preferable
Cushion performance, effectively buffer vehicle impact force, so that accident injury is reduced to minimum.
Detailed description of the invention
Fig. 1 is a kind of positive structure schematic of safety-type buffer guardrail for bridge proposed by the present invention；
Fig. 2 is a kind of side structure schematic diagram of safety-type buffer guardrail for bridge proposed by the present invention.
In figure: upright post rod 1, cross bar 2, guardrail board 3, shaft 4, crossbeam 5, push rod 6, limiting slot 7, limited block 8, spring 9.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-2, a kind of safety-type buffer guardrail for bridge is adjacent including the upright post rod 1 being mounted equidistant in bridge two sides
Guardrail board 3 is equipped between two upright post rods 1, the upper end of each upright post rod 1 is equipped with what one end extended to road surface
The upper end two sides of cross bar 2, the guardrail board 3 are rotatably installed in the one end of cross bar 2 far from upright post rod 1, the guardrail by shaft 4
The lower end two sides of plate 3 are rotatably connected to push rod 6, and the lower end of the two neighboring upright post rod 1 is respectively connected with crossbeam 5, the crossbeam 5
Side close to guardrail board 3 is symmetrically arranged with two limiting slots 7, is equipped with limited block 8 in the limiting slot 7, the limited block 8 with push away
Bar 6 is connected, and spring 9 is equipped between the limited block 8 and the bottom of limiting slot 7, the guardrail board 3 is by outline border and is arranged outside
Wire rope net surface composition in frame, the minimum activity point of view of the guardrail board 3 are 30 degree, are installed using the guardrail board of activity setting
On the pillar of seven fonts, the lower end of guardrail board uses elastic construction, and when vehicle hits guardrail, guardrail board has preferable slow
Punching performance effectively buffers the impact force of vehicle, accident injury is made to be reduced to minimum.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
