Abstract

The invention relates to a bracket and a construction method for the construction of the zero block of an over-wide and short pier box girder, belonging to the field of road and bridge construction. The main steps include: installing triangular brackets around the pier, and installing the triangular brackets on the embedded parts of the brackets in the pier; placing distribution beams above the triangular brackets, placing external formwork on the distribution beams, and installing inner Formwork; the lower end of the strut is installed on the embedded part of the cap, and the upper end is connected with the distribution beam; after the strut is installed, the concrete of the zero block can be poured.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to a bracket and a construction method for the construction of the zero block of the continuous box girder with an over-wide and short pier. Background technique [0002] Driven by the rapid development of the domestic economy, high-speed railways and expressways have also entered a stage of rapid development. In order to meet the requirements of various regions, continuous girder bridges crossing railways, highways, rivers and canyons are gradually increasing. Generally, the continuous girder bridge is constructed by cantilever casting with hanging baskets, and the zero block is constructed by brackets. However, when the horizontal dimension of the zero block is larger than that of the pier top, and the overhanging dimension is large, it will bring potential safety hazards to the construction. For the construction of bridges such as crossing roads and rivers, there is ...
