Description

A reinforced steel structure bridge prefabricated component

Technical field

The invention relates to the technical field of bridge components, specifically a reinforced steel structure bridge prefabricated component.

Background technique

Bridges generally refer to structures erected over rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern and rapidly developing transportation industry, bridges have also been extended to structures erected to make traffic more convenient across mountain streams, poor geology, or to meet other transportation needs. Bridges generally consist of a superstructure, a substructure, supports and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; the supports are the bridge span structure and piers. Or the force transmission device installed at the supporting location of the bridge abutment; the ancillary structures refer to the bridge head slab, tapered slope protection, bank protection, diversion engineering, etc.

A reinforced steel structure bridge prefabricated component is disclosed in the Chinese invention patent application specification CN213666316U. Although this invention can solve the following problems existing in the process of building steel structure bridges in the prior art: a. Bridge support columns are usually large in size, making it inconvenient for general transportation vehicles to transport them, thereby reducing the efficiency of transporting bridge support columns; b. The assembly steps of various components of bridge support columns in existing steel structure bridges are relatively cumbersome , and a large number of welding methods with slow assembly efficiency are used, thereby reducing the efficiency of assembling the bridge support columns.

However, this reinforced steel structure bridge prefabricated component does not have a strong fixing effect on the steel bars and ignores the instability of the steel bars inside the bridge body. Therefore, we propose a reinforced steel structure bridge prefabricated component to solve the above problems.
