Corbel bracket platform for simultaneous construction of bridge piers and transverse beams and its construction method

Abstract

The invention discloses a corbel bracket platform for bridge pier and transverse straining beam synchronous construction. The corbel bracket platform is characterized in that the positions, with the equal height, in the middle of semicircular steel molds on the two sides of the upper portion of a pier column model (1) are respectively provided with a corbel (2) in a welding mode, jacks (3) are installed on the corbels (2), I-beams (4) are placed on the jacks (3) in the horizontal direction, the I-beams (4) on the two sides of the pier column model (1) are connected together through pulling rods (5) and fastened on the pier column model (1), and distributive beams (6) are placed between the I-beams (4) at equal intervals. The invention further discloses a construction method of the corbel bracket platform. According to the corbel bracket platform, synchronous construction of a pier column and a transverse straining beam is achieved, the construction cycle period of components below a bridge is shortened, and the bridge construction progress is accelerated. Meanwhile, compared with a traditional construction scheme, the input material cost is low, materials of the platform of the transverse training beam can be completely recycled for coping beam construction, and the circulating utilization rate of the materials is high.

Description

technical field [0001] The invention relates to a construction bracket platform suitable for bridge piers designed with transverse tie beams, in particular to a novel corbel bracket platform for synchronous construction of bridge piers and transverse tie beams and a construction method thereof. Background technique [0002] When designing high bridge piers, it is necessary to set transverse beams between the two pier columns to increase the lateral stiffness of the pier body and prevent the lateral instability of the pier body. The traditional methods for erecting the construction platform of high pier transverse tie beams include bracket method, steel rod method and hoop method. [0003] The traditional method has the following disadvantages: (1) The traditional method of the transverse tie beam needs to complete the construction of the pier column first, set up the bracket between the two pier columns, put steel rods on the pier columns or install hoops, and then build the...
