Description
Technical Field
The utility model relates to a cast-in-place simple box girder steel external mold is balanced from balanced hoist device.
Background
The cast-in-place simply supported beam steel formwork is installed before concrete pouring, and adverse condition influence is avoided. And the steel formwork is dismantled, namely the steel formwork is difficult to dismantle due to the influence of the concrete of the flange plate at the top of the steel formwork in the dismantling process after the concrete is poured. When a steel side die (a box girder steel outer die) of a box type cast-in-place simply supported beam is dismantled at present, a hoisting point is generally arranged on a steel die main truss outside a flange plate, and the template can be turned over at the moment of template separation in the hoisting process (namely, the center of gravity of the template is not on a vertical line with the hoisting point at the lower part of the flange plate, and the center of gravity of the steel template is turned over to the point of the hoisting point to be coincided with the center of gravity in the hoisting process by taking the hoisting point as a circle center). In the hoisting process, the template is overturned to cause the bracket to be impacted, and the risk of bracket collapse is generated. And the template is separated from the beam body and deflects to generate falling, which easily causes the consequence of crane wire rope breakage or crane overturn.
