Climbing formwork device for three-leaf pin hinge bridge garden column pier

Abstract

The invention discloses a climbing form device and a construction method for a three-leaf pin hinged bridge garden column pier, which is applied to the construction of a bridge garden column pier. The three-leaf pin hinge bridge garden column pier column climbing formwork device is divided into a formwork system, a platform system, a hydraulic jacking and fulcrum conversion system, and a ladder channel system. The structure system of the device of the present invention adopts the concept of climbing formwork, the mechanical principle of pin hinge formwork structure to increase the degree of freedom of the plate, the characteristic of self-locking function of the hoop combined with the round wedge-shaped support, the design of the combined through-long pin shaft, and the synchronization of the ladder passages. The innovative thinking of upgrading, lengthening the bottom and connecting to standard segments solves the technical difficulties in improving the two-leaf bolted formwork structure, which has been used for decades, the small amount of physical engineering, the high cost of investment in measures, and the poor safety and controllability of a large number of high-altitude operations. , The problem of high labor intensity. The popularization and application of the present invention will have a revolutionary influence on the construction technology of the cylindrical bridge pier, and the construction of the cylindrical bridge pier will enter the era of the three-leaf pin hinged formwork structure.

Description

technical field [0001] The technology of the invention belongs to the technical field of pouring bridge garden column pier construction, and in particular relates to a three-leaf pin hinge bridge garden column pier climbing formwork system and a construction method. Background technique [0002] my country's highway bridges and municipal viaducts are generally designed with garden column piers (unless special landscape requirements) when the bridge pier column height is less than 30 meters. The construction of garden column piers with a height of 30 meters and below is extremely common. For a long time, the construction method is to use two-leaf and half-circular formwork blocks to buckle and bolt to form an integral cylindrical formwork system. This construction method has been used for decades. Although there are some small improvements in the formwork structure and construction platform, However, there is no change in the connection method of the two-leaf semi-circular fo...
