Description

Technical Field

[0001] The utility model relates to the technical field of steel frame bridge erection, in particular to an installation structure of a steel frame bridge panel. Background Art

[0002] A steel frame bridge refers to a bridge in which the beams and piers of the superstructure of the bridge are consolidated into a whole to form a rigid structure. Since the steel frame components of the steel frame bridge can withstand both bending and axial forces, and the height of the beams is relatively short, it is suitable for use as a cross-line bridge. Steel frame bridges can generally be divided into three types: continuous steel frame, slanted leg steel frame and T-shaped steel frame. Among them, the continuous steel frame bridge has good seismic resistance, the slanted leg steel frame bridge is light and beautiful, and the T-shaped steel frame bridge is a cantilever extending from the pier, shaped like a T, hence the name. This type of bridge can reduce vibration and improve elasticity. It is often used in large-span bridges across deep water, deep valleys, large rivers and rapids. It is widely used in roads within hydropower stations. It has the characteristics of convenient and fast construction, safety, and low cost. The subsequent dismantling and recycling rate is also high, which improves the reuse rate of resources and reduces economic costs and waste of resources.

[0003] A bridge deck needs to be clamped at the upper end of a steel frame bridge for the passage of pedestrians and vehicles. In the prior art, the bridge deck is usually installed by welding, which makes the installation of the bridge deck slow, and the welding fixation method increases the difficulty of subsequent dismantling.
