In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a guardrail for urban traffic, includes at least three stand and many wears to establish the guardrail beam slab through all stands, and many guardrail beam slabs set up for longitudinal separation, are connected with on every stand to be used for hugging closely the connecting piece of fixing on the stand with guardrail beam slab, every guardrail beam slab's both ends all overlap and are equipped with the end cover that is used for closing cap guardrail beam slab tip, end cover and the connecting piece fixed connection that is located the stand at both ends.
The connecting piece is of a U-shaped bolt structure.
The parts of the guardrail beam plate except the two end parts are clamped and penetrate through the space defined by the connecting piece and the corresponding upright post.
The guardrail beam plate comprises a belt core layer woven by industrial yarns and a protective layer coated on the periphery of the belt core layer.
The protective layer is an engineering plastic layer or a modified resin layer.
The outer wall of the protective layer is provided with a plurality of convex edges extending along the length direction of the guardrail beam plate.
The utility model has the advantages that: compared with a steel structure guardrail, the guardrail beam plate of the guardrail for urban traffic mainly comprises a belt core layer woven by industrial yarns and an engineering plastic layer or a modified resin layer coated on the periphery of the belt core layer, has the characteristics of ageing resistance, good toughness, high impact strength, excellent impact energy absorption capacity, excellent deformation relaxation performance and the like, can greatly slow down the impact force when a vehicle collides with the guardrail, improves the protection performance of the guardrail, can reduce the energy consumption and pollution during the production of the guardrail, and reduces the transportation cost of the guardrail; the tip of guardrail beam slab and guardrail beam slab all are connected with the stand through U type bolted construction's connecting piece except that an at least department of tip, the tip of guardrail beam slab protects and end cover and the connecting piece fixed connection that corresponds through the end cover, the integral connection is firm, the installation, it is convenient to dismantle, can not destroy the structure of guardrail beam slab during the installation, the buffering effect of guardrail beam slab has been ensured, be more applicable to the safety protection of longer straight line road, very big realistic meaning and use value have.

In the figure: the guardrail comprises a column 1, a guardrail beam plate 2, a belt core layer 21, a protective layer 22, ribs 23, a connecting piece 3, an end cover 4, a front plate 41, a top plate 42, a bottom plate 43 and a side sealing plate 44.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 to 8, a guardrail for urban traffic comprises at least three upright posts 1 and a plurality of guardrail beam plates 2 penetrating through all the upright posts 1, wherein the guardrail beam plates 2 are arranged at longitudinal intervals, the number of the guardrail beam plates 2 at the longitudinal intervals is determined according to the height of the upright posts 1, and the upright posts 1 are provided with post covers for sealing the tops of the upright posts 1, so that the interior of the upright posts 1 can be prevented from being corroded by rainwater.
Be connected with on every stand 1 and be used for hugging closely the connecting piece 3 of fixing on stand 1 with guardrail beam slab 2, every guardrail beam slab 2's both ends all overlap and are equipped with the end cover 4 that is used for the tip of closing cap guardrail beam slab 2, end cover 4 and the 3 fixed connection of connecting piece on the stand 1 that are located both ends.
The connecting piece 3 is of a U-shaped bolt structure, and the connecting piece 3 comprises a vertical part and two screw rod parts which are connected to two ends of the vertical part respectively. The utility model discloses in, end cover 4 can adopt the box structure of two kinds of differences, and first end cover 4's structure is: the end cover 4 comprises a front plate 41 attached to the surface of the end part of the guardrail beam plate 2 facing away from the upright post 1, a top plate 42 attached to the upper surface of the end part of the guardrail beam plate 2, a bottom plate 43 attached to the lower surface of the end part of the guardrail beam plate 2 and a side sealing plate 44 attached to the end surface of the end part of the guardrail beam plate 2, wherein the top plate 42, the bottom plate 43 and the side sealing plate 44 form a three-side enclosure frame type structure, the front plate 41, the top plate 42 and the bottom plate 43 all penetrate through the space between the two screw rod parts of the connecting piece 3, and the front plate 41 is welded and fixed with the vertical part of; the second end cover 4 is structured as follows: the end cover 4 includes the front bezel 41 with the surface laminating of the back stand 1 of 2 tip of guardrail beam slab, the roof 42 with the upper surface laminating of 2 tip of guardrail beam slab, the bottom plate 43 with the lower surface laminating of 2 tip of guardrail beam slab and the side seal board 44 with the terminal surface laminating of 2 tip of guardrail beam slab, the roof 42, bottom plate 43 and side seal board 44 form a three-sided frame formula structure, the front bezel 41 passes between two screw rod portions of connecting piece 3 and the vertical welded fastening of front bezel 41 and connecting piece 3, roof 42 and bottom plate 43 are the screw rod portion that sets up nevertheless roof 42 and bottom plate 43 all do not all exceed connecting piece 3 from side seal board 44 to being close to the extension of connecting piece 3 direction.
