Abstract

The invention relates to a box girder overturning-type flange plate cast-in-place mould, which can achieve self-traveling and has accurate positioning precision, convenient operation and good reliability and safety, and which is structurally characterized in that the mould comprises a mould carriage, wherein two sides of the mould carriage are symmetrically respectively provided with an overturning mechanism, the overturning mechanisms are connected with a flange plate forming mould; and the flange plate forming mould is connected with the girder.

Description

technical field [0001] The invention relates to the field of on-site cast-in-place casting of box girders of railway passenger dedicated lines, in particular to an in-situ cast-in-place mold for overturned flange plates of box girders. Background technique [0002] At present, the box girder of the railway passenger dedicated line is divided into two methods: cast-in-place and prefabricated according to different manufacturing methods. Here, it involves cast-in-place box girder molds. The cast-in-place box girder molds currently used are mainly disassembled molds. From the perspective of use function Looking at the disassembled mold, there are mainly the following disadvantages: [0003] 1) The degree of automation is poor, the mold needs to be assembled and disassembled in blocks, and the work efficiency is low. [0004] 2) The positioning accuracy is poor, and the surface quality of the beam body is poor. [0005] 3) There is no self-propelled function, and auxiliary mec...
