Problems solved by technology

[0004] The object of the present invention is to provide a kind of prefabricated guardrail for steel bridge and its assembling method, to solve the problem that the prefabricated steel bridge is used in military transportation, rescue and disaster relief, national defense construction, water conservancy project, road traffic etc. The field plays an important role. When a vehicle accidentally collides with the guardrail on this road section, it is difficult to carry out rescue at a relatively fast speed in most cases. However, there is no emergency treatment device on the current assembled guardrail, and it is difficult to carry out emergency treatment for vehicles that accidentally collide. The problem

Abstract

The invention discloses an assembly type guardrail for a steel bridge and an assembly method of the assembly type guardrail, relates to the related field of steel bridge assembly, and aims to solve the problems that in the prior art, due to the fact that an assembly type steel bridge plays an important role in the fields of military transportation, rescue and relief work, national defense construction, water conservancy projects, road traffic and the like, when a vehicle accidentally collides with the guardrail on the road section, rescue is difficult to implement at a high speed in most cases, and an existing assembly type guardrail is not provided with an emergency treatment device, so that emergency treatment is difficult to carry out on the vehicle which is accidentally collided are solved. The number of the fixing vertical piers is two, rear fixing rods are fixedly connected with the rear portions of the upper ends of the fixing vertical piers, front fixing rods are arranged on the front portions of the upper ends of the fixing vertical piers, a rear protection assembly is arranged between the two rear fixing rods, a guardrail body is arranged between the two front fixing rods, the guardrail body comprises a middle guardrail plate, and a rectangular groove hole is formed in the middle guardrail plate.

Description

technical field [0001] The invention relates to the related field of steel bridge assembly, in particular to an assembled guardrail for a steel bridge and an assembly method thereof. Background technique [0002] Prefabricated steel bridges (also known as Bailey steel bridges) have the characteristics of simple structure, lightweight components, convenient transportation, flexible combination, fast erection, convenient disassembly and assembly, and reusable components. At the same time, they have large bearing capacity, strong structural rigidity, Long fatigue life and other advantages, and can be combined into bridges with different spans, types and uses according to the needs of engineering design. be widely used. With the acceleration of my country's modern urban construction, the environmental problems generated in urban construction have attracted increasing attention. The prefabricated steel bridge technology has brought convenience to the construction of urban prefab...
