Abstract

The invention belongs to the technical field of bridge engineering construction, and particularly relates to a large pier reinforcing steel positioning device and an installation method thereof. The large pier reinforcing steel positioning device includes a bottom layer reinforcing steel positioning fixture and an upper layer reinforcing steel positioning fixture, the bottom layer reinforcing steel positioning fixture includes first positioning reinforcing steel, second positioning reinforcing steel and first strengthening reinforcing steel, and the upper layer reinforcing steel positioning fixture includes third positioning reinforcing steel, fourth positioning reinforcing steel, fifth positioning reinforcing steel, sixth positioning reinforcing steel, second strengthening reinforcing steel, and third strengthening reinforcing steel. According to the large pier reinforcing steel positioning device and the installation method thereof, by arranging the bottom layer reinforcing steel positioning fixture and the upper layer reinforcing steel positioning fixture, accurate positioning of reinforcing steel can be realized, and the phenomena of uneven spacing of the reinforcing steel, displacement of the reinforcing steel and instability of a reinforcing cage are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering construction, and in particular relates to a large-scale bridge pier reinforcement positioning device and an installation method. Background technique [0002] The steel bar positioning fixture is a positioning device used in reinforced concrete structures to ensure that the spatial position of the stressed steel bar meets the design requirements, the integrity and stability of the steel bar skeleton, and the thickness of the steel bar cover meets the design and specification requirements. In the construction process of large bridge piers, the number of steel bars is large, the spacing may change with the height of the bridge piers, and the number of steel bar layers increases. The traditional positioning method for bridge pier reinforcement is the "distributed positioning method", that is, a single steel bar is used to shape the top surface of the cap steel bar along the pier line, and...
