A temporary reinforcement structure for a bridge

Abstract

The application provides a temporary reinforcing structure for a bridge, and relates to the field of bridge construction; the temporary reinforcing structure comprises an arched support assembly, an elastic support seat and a cross beam; the two ends of each arched support assembly are connected to two adjacent pier columns in the length direction of the bridge body through a first connecting piece; the two ends of each arched support assembly between the front side and the back side are connected to two adjacent transverse steel tie beams of the bridge body through a first connecting piece; each adjacent arched support assembly is connected through at least one cross beam extending in the width direction of the bridge body; at least one elastic support seat is arranged between the top of the arched support assembly and the lower part of the bridge body; through the above structure, sufficient support can be provided in the length and width directions of the bottom of the bridge body; the overall structure is relatively simple, reasonable in design, convenient in construction, good in construction effect, can be quickly completed on the construction site, and has relatively low construction cost.

Claims

1. A temporary reinforcement structure for a bridge, the bridge comprising a bridge body and a plurality of piers located beneath the bridge body, wherein adjacent piers are connected by transverse steel tie beams along the width direction of the bridge body; characterized in that, The temporary reinforcement structure includes arched support components, elastic support bases, and crossbeams; Among the multiple arched support components located on the front and rear sides along the width direction of the bridge body, the two ends of each arched support component are connected to two adjacent piers in the length direction of the bridge body through a first connector; among the multiple arched support components located between the front and rear sides of the bridge body along the width direction, the two ends of each arched support component are connected to two adjacent transverse steel beams in the length direction of the bridge body through a first connector. Furthermore, adjacent arch support components are connected by at least one crossbeam extending along the width of the bridge. At least one of the elastic support seats is provided between the top of the arched support assembly and the lower part of the bridge body.

2. The temporary reinforcement structure for bridges according to claim 1, characterized in that, The arched support assembly includes an arched support base and two connecting columns; The two legs of the arched support are each connected to a connecting column, and the bottom of the connecting column is connected to the pier column or the transverse steel beam through a first connector.

3. The temporary reinforcement structure for bridges according to claim 2, characterized in that, The first connector is a clamp, and the gap between the clamp and the pier column is filled with epoxy mortar.
