Reinforcing steel formwork supporting rack for thin-walled hollow high pier and construction method

Abstract

The invention provides a reinforcing steel formwork supporting rack for a thin-walled hollow high pier and a construction method. The reinforcing steel formwork supporting rack comprises a reinforcing steel formwork supporting framework and an operation platform, wherein the reinforcing steel formwork supporting framework comprises vertical columns, a transverse bridge direction cross rod and a longitudinal bridge direction cross rod, wheel discs are arranged at the bottom ends of the vertical columns, the bottom ends of the vertical columns are in welded connection with the wheel discs, the wheel discs are fixedly connected with rollover purlins of set-shaped steel formworks through bolts, connecting steel plates are welded at the top ends of the vertical columns and connected with the longitudinal bridge direction cross rod at the top through bolts, and the transverse bridge direction cross rod is perpendicular to the longitudinal bridge direction cross rod, erected on the top surface of the longitudinal bridge direction cross rod and connected with the longitudinal bridge direction cross rod though the bolts; and operation platform comprises triangular reinforcing steel brackets and operation platform stirrups, vertical supports of the triangular reinforcing steel brackets are attached to the tops of the outer walls of the vertical rods and are in welded connection, the operation platform stirrups are uniformly distributed, and the end parts are undertook transversely on the triangular reinforcing steel brackets. The reinforcing steel formwork supporting rack for the thin-walled hollow high pier and the construction method have the advantages that thickness of a protective layer is easy to control, safety and reliability are achieved, construction cost is saved and the like.

Description

technical field [0001] The invention relates to a steel bar formwork support and a construction method, in particular to a thin-walled hollow high pier steel bar formwork support and a construction method. Background technique [0002] Expressways develop towards mountainous areas, and there are more and more bridges crossing mountains and rivers and reservoirs. Due to the terrain, the piers are relatively high, so they are often designed as high piers and thin-walled hollow piers, and the steel bar binding installation and construction of towering thin-walled hollow piers are constructed by the overturning method. There is a problem. Because there are two conventional construction methods: one is to build a steel pipe support around the pier column, which is also a working platform for going up and down stairs and installing steel bars, and the steel pipe support set up should be higher than the height of the steel bar installed each time, and then in the middle of the sup...
