The invention discloses a prefabricated bridge bent cap positioning device and a using method thereof, relates to the technical field of bridge engineering, and aims to solve the problems that a large number of supports and formworks need to be erected, manpower consumption is large and construction efficiency is low during existing bent cap construction. The number of square piers is two, bases are installed below the two square piers, a straining beam is installed between the two square piers, a construction platform is installed on the peripheries of the two square piers, a plurality of I-shaped steel frames are installed on the lower surface of the construction platform, reinforcing steel bar supporting tables are arranged on one sides of the two square piers, a bent cap formwork is installed above the two square piers, a positioning device body is installed above the bent cap formwork, two electric guide rails are arranged on the positioning device body, and the two electric guide rails are arranged on the two sides of the bent cap formwork correspondingly.
Description
technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a positioning device for a prefabricated and assembled bridge cover beam and a method for using the same. Background technique [0002] The cap beam refers to the beam set on the top of the bent pile pier in order to support, distribute and transmit the load of the superstructure, also known as the cap beam. Reinforced concrete or less-reinforced concrete crossbeams are set on bridge piers or row piles, and their main function is to support the upper structure of the bridge and transfer all loads to the lower structure. Some bridge piles are directly connected to the cover beam, and some bridge piles are connected to the column and then connected to the cover beam. In bridge design, column piers are commonly used structural types. For simply supported bridges, the cover beam is an important component connecting the upper and lower structures. The load of the upper st...
