Abstract

The invention relates to the field of general assembly of girder sections of steel box girders, in particular to a tool installation mould for upside-down construction of a multi-curve superimposed steel box girder and a construction method thereof. The tool installation mould for the upside-down construction of the multi-curve superimposed steel box girder includes a box body, an upper column and a lower column are fixed to the box body and located on and under the box body respectively, and the lower end of the lower column is fixed into a base; the box body is internally provided with a worm wheel and worm mechanism, lead screws positioned inside the upper column and the lower column are arranged on worm wheels, and the top portions of the lead screws are provided with supporting heads. The adjustable mould has excellent universality, and by utilizing the self-locking and adjustable properties of the adjustable mould, the adjustable mould can serve as an adjustable moulding bed support for changes of curved section frame lines and be adjusted in the vertical direction.

Description

technical field [0001] The invention relates to the field of general assembly construction of steel box girder girder sections, in particular to a multi-curve superimposed steel box girder inverted construction tooling and a construction method thereof. Background technique [0002] In order to meet the requirements of manufacturing, transportation and installation, long and large steel box girders require components to be assembled in sections in the manufacturing plant; with the popularization and application of steel structures in the field of bridges, the structural forms of multi-curve superimposed steel box girders are gradually increasing, and the curved surface Segmental assembly is relatively complicated, and the traditional mold positioning cannot be reused after segmental assembly, and adopts a cycle mode of construction-cutting-construction (traditional steel box-beam assembly tire frames mostly use rigid frame structures as Then the positioning code boards are w...
