The utility model provides a guardrail, it protects the hurdle front side establish the second guardrail and constitute before buffering, rear side establish the guardrail net and constitute the back protection, the rail guard form of protection after the main part in the buffering before this kind, safety protection ability is strong.

Description

A kind of bridge security type guardrail

Technical field

This utility model relates to Bridge guardrail technical field, is specifically related to a kind of bridge security type guardrail。

Background technology

The Bridge guardrail that current China commonly uses is fence type, and due to structure, mechanical strength is inadequate, it is impossible to meet necessary requirement of shelter, it is easy to potential safety hazard occur。Owing to when vehicle runs, inertia is big, simple stiff safety fence major part is single support bar, and protection effect is poor, it is easy to broken by vehicle, falls down from bridge floor, causes the very big casualties。

Utility model content

Technical problem to be solved in the utility model is to provide the bridge security type guardrail that a kind of security protection ability is strong。

For solving above-mentioned technical problem, this utility model provides techniques below scheme: a kind of bridge security type guardrail, including the guardrail rack being fixed on bridge, the first guardrail of being interspersed between guardrail rack, also include the second guardrail and guardrail net, highlighting forward in the middle part of described guardrail rack leading flank and be extended with fixed part, described second guardrail is interspersed between fixed part；Described guardrail net includes guardrail rack and safety net, described guardrail rack includes being placed in the support body of both sides, being respectively fixedly connected with the fixing plate between support body top, both sides and between bottom, described support body top is fixedly connected on guardrail rack top, bottom is fixedly connected on bridge, and described safety net is fixed between the support body of both sides。

On such scheme basis preferentially, also include Buffer Unit, described Buffer Unit includes buffering brute spring, bracket, described fixed part longitudinally offers the dashpot corresponding with Buffer Unit, described bracket is fixed on the second guardrail, and dashpot medial surface is fixed in described buffering brute spring one end, opposite side is fixedly connected on bracket。

On such scheme basis preferential, described second guardrail includes being placed in first railing at two ends, for connecting the second railing of two ends the first railing, and described second railing external diameter is more than the first railing external diameter, and described first railing and the second railing are one-body molded。

On such scheme basis preferentially, described second guardrail is provided with a reflector layer。

This utility model compared with prior art has the beneficial effect that the guardrail that this utility model provides, set buffering before the second guardrail is constituted on front side of its guardrail rack, rear side sets guardrail net and constitutes rear protecting, the guard rail form of main body rear protecting in buffering before this, security protection ability is strong；Meanwhile, guardrail rack is fixed at the support body top of guardrail net, bridge is fixed in bottom, and structural stability is strong。

Accompanying drawing explanation

Fig. 1 is this utility model structural representation；

Fig. 2 is this utility model Buffer Unit structural representation；

Fig. 3 is this utility model the second guard bar structure schematic diagram。

Number in the figure is: 1-guardrail rack, 11-fixed part, 111-dashpot, 2-the first guardrail, 3-the second guardrail, 31-the first railing, 32-the second railing, 4-guardrail net, 41-guardrail rack, 411-support body, 412-fixes plate, 42-safety net, and 5-cushions brute spring, 6-bracket, 7-bridge。

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model。

In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model。

Referring to figs. 1 through Fig. 3 it can be seen that a kind of bridge security type guardrail, including the guardrail rack 1 being fixed on bridge 7, the first guardrail 2 of being interspersed between guardrail rack 1, also include the second guardrail 3, Buffer Unit and guardrail net 4。

Wherein, highlighting forward and be extended with fixed part 11 in the middle part of described guardrail rack 1 leading flank, described second guardrail 3 is interspersed between fixed part 11；Described Buffer Unit includes buffering brute spring 5, bracket 6, described fixed part 11 longitudinally offers the dashpot 111 corresponding with Buffer Unit, described bracket 6 is fixed on the second guardrail 3, and dashpot 111 medial surface is fixed in described buffering brute spring 5 one end, opposite side is fixedly connected on bracket 6。First errant vehicle can strike the second guardrail 3, utilizes buffering brute spring 5 to cushion vehicle impact force, serves as the front cushioning effect of guard rail。

Described second guardrail 3 includes being placed in first railing 31 at two ends, for connecting the second railing 32 of two ends the first railing 31, described second railing 32 external diameter is more than the first railing external diameter 31, and described first railing 31 and the second railing 32 are one-body molded；Improve impact resistance intensity in the middle part of the second guardrail 3。Described second guardrail 3 is provided with a reflector layer, reminds car owner to drive。

Wherein, described guardrail net 4 includes guardrail rack 41 and safety net 42, described guardrail rack 41 includes being placed in the support body 411 of both sides, being respectively fixedly connected with the fixing plate between both sides support body 411 top and between bottom, described support body 411 top is fixedly connected on guardrail rack 1 top, bottom is fixedly connected on bridge 7, structural stability is strong, and described safety net 42 is fixed between both sides support body 411, it is prevented that errant vehicle is gone out bridge floor and caused heavy damage, being also prevented from pedestrian's accidental falling, safety coefficient is high。

The guardrail that this utility model provides, sets on front side of its guardrail rack 1 that second guardrail 3 constitutes front buffering, rear side sets guardrail net 4 and constitutes rear protecting, and the guard rail form of main body rear protecting in buffering before this, security protection ability is strong。

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model。
