Bracket support supporting mechanism of cast-in-place box girder self-propelled movable formwork system

Abstract

The utility model relates to a bracket support supporting mechanism of a cast-in-place box girder self-propelled movable formwork system, which is characterized in that a shear-resistant beam box is fixed through pre-buried rake ribs, a bracket bottom expansion end is inserted into the shear-resistant beam box, and the bracket support supporting system is supported through the shear-resistant beam box, so that crushing or shearing of local concrete of a pier column due to stress concentration effect is effectively reduced, and the construction efficiency is improved. The intactness of the pier column is ensured; the lower portion of the bracket support tightly holds a pier column through an L-shaped pier holding rib plate, the upper portion of the bracket support is oppositely pulled and fixed through a high-strength finish rolling threaded rib, it is effectively guaranteed that the bracket support is not loosened or deviated in the longitudinal moving process of the movable formwork system, and the firmness of the support is improved; a platform steel plate with a groove is arranged on the upper portion of the bracket support, steel balls are arranged in the groove, the movable trolley horizontally moves on the platform steel plate under the action of the jack, resistance is reduced through the action of the steel balls, horizontal and transverse automatic movement of a main beam of the movable formwork system is achieved, and the construction efficiency of hole passing, formwork erecting and formwork removing of the movable formwork system is improved.
