Description

Fully assembled steel guardrail

technical field

The utility model relates to the field of highway guardrails, in particular to a fully assembled steel guardrail.

Background technique

In recent years, with the rapid development of expressways in our country, the traffic volume is increasing day by day, and the incidence of traffic accidents is getting higher and higher. The problem of traffic safety is particularly important. Therefore, when designing traffic safety facilities, their safety and reliability should be considered, especially the design of guardrails. It is the first barrier to prevent vehicles from rushing out of the road. the size of the loss.

At present, the guardrails commonly used in highways include concrete guardrails, corrugated beam steel guardrails, and cable guardrails. Concrete guardrails have high strength, slow construction speed, and a greater sense of oppression; corrugated beam steel guardrails are fast in construction, have a good line of sight induction function, and have a beautiful appearance; cable guardrails are more complicated in construction technology and are generally used less. For the central divider guardrail, under the condition of the width of the central divider, the first choice is to use the corrugated beam steel guardrail, and the second is to choose the concrete guardrail; for the roadside guardrail, generally choose the corrugated beam steel guardrail. Option to use concrete barriers.

However, the existing various guardrails have the disadvantages of slow construction, being installed in the middle or both sides of the road to easily block the view, and the strength of the guardrails cannot meet the requirements.

Utility model content

The purpose of the utility model is to provide a fully-assembled steel guardrail that can be constructed quickly, has wide field of view, high strength level and good economy. It can be used on middle bridges, large bridges or road sections where serious accidents may occur when vehicles cross the bridge, and the anti-collision level can reach SS level.

The technical scheme of the utility model is as follows:

The fully assembled steel guardrail is composed of uprights, beams, supporting angles, water retaining plates and bases. The uprights are welded to the supporting angles and connected to the beams by bolts to form a whole. The water retaining plates are welded above the uprights. The base is located below the column.

Set up four beams at equal intervals in the vertical direction and open bolt holes to connect them with the supporting angle steel bolts. Set up a beam expansion joint every 6m along the longitudinal direction, and connect two adjacent beams in the vertical direction through a telescopic sleeve. The telescopic sleeve adopts cold bending The square hollow section steel is 104×104×8, and bolt holes are opened, and bolt holes are also opened corresponding to the position of the beam, and are fixed by bolts.

The column is made of hot-rolled H-shaped steel HM200×150, and the distance between two adjacent columns is 1.5m.

The beam is made of cold-formed square hollow steel 120×120×6.

The water retaining plate is a rectangular steel plate.

The base is a concrete base or a steel base.

Compared with the prior art, the utility model has the following advantages: a fully assembled steel guardrail is created, and the anti-collision level can reach SS level, which can effectively prevent vehicles from breaking the guardrail or climbing over the guardrail; The connection of the crossbeam is bolted, the welding workload on site is less, and the guardrail is divided into 6m as a section, which realizes the rapid construction of the full assembly of the guardrail; the durability is good, the maintenance cost is low, the economy is good, and the partial replacement of the guardrail is convenient ;Beautiful appearance, wide field of view, better coordination with the surrounding environment.

detailed description

Below in conjunction with the specific examples and accompanying drawings, the specific implementation of the present utility model will be further described.

The fully assembled section steel guardrail provided by the utility model has an anti-collision level up to SS level, and can be used in middle bridges, large bridges or road sections where serious accidents may occur when vehicles cross the bridge. As shown in Figure 1, the fully assembled steel guardrail is composed of a column 1, a beam 2, a support angle steel 3, a water retaining plate 4, and a base 5; The water baffle 4 is welded on the top of the column 1, and the base 5 is located below the column 1.

Column 1 is made of hot-rolled H-shaped steel HM200×150, and the distance between two adjacent columns 1 is 1.5m. The crossbeam 2 adopts cold-formed square hollow section steel 120×120×6, and four crossbeams 2 are arranged vertically and equidistantly, and bolt holes are opened to connect with the supporting angle steel 3 by bolts. As shown in Figure 2-3, a beam expansion joint is set every 6m in the longitudinal direction, and two adjacent beams 2 in the longitudinal direction are connected by a telescopic sleeve 7 . The telescopic sleeve 7 adopts cold-formed square hollow section steel 104×104×8, and provides bolt holes, corresponding to the position of the beam 2, also provides bolt holes, and adopts bolt 6 to fix it.

As shown in Figure 1, the water retaining plate 4 is a rectangular steel plate. The base 5 is a concrete base or a steel base, which connects the column 1 with the bridge or road surface structure.
