Steel plate welded horn bracket highway bridge guardrail support frame high-speed anti-collision isolation handrail

  Specification for bridge guardrail support: bridge guardrail refers to the guardrail set on the bridge
Its purpose is to prevent out of control vehicles from crossing the bridge
It has the function of preventing vehicles from breaking through, crossing, crossing the bridge and beautifying the bridge building

Structure:
The selection of the form of bridge guardrail shall first determine the anti-collision grade according to the highway grade, comprehensively considering its safety, coordination, the characteristics of the objects to be protected and the site geometric conditions, and then according to its own structure
Economic, construction, maintenance and other factors
The embedment methods include direct embedment of columns, flange connection and casting of bridge guardrails and bridge decks into one through force transfer reinforcement,
When conditions permit, removable guardrails can be used

 
Classification:
There are many methods to divide the types of bridge guardrail supports
In addition to the setting position, they can also be divided according to structural characteristics, anti-collision performance, etc
According to the setting position, it can be divided into Bridge side guardrail, bridge median guardrail and guardrail at the boundary of pedestrian and lane; According to the structural characteristics, it can be divided into beam column type (metal and concrete) guardrail, reinforced concrete wall type expanded guardrail and combined guardrail; According to the anti-collision performance, it can be divided into rigid guardrail, semi-rigid guardrail and flexible guardrail

 
Bridge guardrail support device method: according to its mechanical characteristics, anti-collision guardrail can be divided into rigid guardrail, semi-rigid guardrail and flexible guardrail
For super major bridges, major bridges and medium-sized bridges on expressways, first-class highways or high-class highways, bridge guardrails should be set unconditionally
Generally, super major, large and medium-sized bridges on highways should also be set with bridge guardrails if conditions permit
The anti-collision guardrail support is used to support the anti-collision guardrail, so as to close both sides along the line and prevent human, livestock and non motor vehicles from entering the highway
This product has fewer production links, the production process is easy to control, and the batch output is large
It will have a certain impact on high-speed driving safety, driving comfort, highway scene and project cost
