Abstract

The invention provides a variable-width box girder mobile formwork device and a construction method. A variable-width box girder mobile formwork device includes a main beam, a temporary main beam, a beam, a corbel beam, a bracket, and a hydraulic pump. Station, motion mechanism and electrical system, the corbel is fixed on the bridge pier through corbel columns, a main girder is arranged on both sides of the top of the corbel, and at least one main girder is arranged between the two main girders. Beam, the main beam and the temporary main beam are all set on the corresponding kinematic mechanism through the corresponding bracket, the kinematic mechanism is set on the corbel beam, the kinematic mechanism and the corbel beam, the kinematic mechanism and the bracket There is a mobile hydraulic cylinder between the bracket and the temporary main beam and between the bracket and the main beam. The mobile hydraulic cylinder is connected with the hydraulic pump station through the oil pipe. The main beam and A crossbeam is arranged on the upper side of the temporary main beam, and an inner mold and an outer mold composed of wear-resistant templates are arranged on the upper side of the crossbeam. The invention also provides a construction method.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and relates to a mobile formwork, in particular to a variable-width box girder mobile formwork device and a construction method. technical background [0002] Mobile formwork has been widely used in the continuous beam construction of highways, road bridges and railway bridges. However, due to structural limitations, the mobile formwork is generally constructed for constant-section bridges. The emergence of ramps in urban viaducts makes the objects of construction change from general bridges with equal cross-section linear structures to bridges with curved structures, and even bridges with variable width structures, which puts forward higher requirements for the use of mobile formwork systems. The general mobile formwork conventionally used in the laying of equal-section bridges can no longer meet the construction of variable-width bridge concrete pouring. Therefore, a new type of br...
