Steel-concrete structure hanging box and dismantling method thereof

Abstract

The invention discloses a steel-concrete structure hanging box which comprises a reinforced concrete base board and steel formworks fixed at the periphery of the base board, wherein the steel formworks are divided into steel side formworks and steel end formworks, cross beams are arranged at the tops of the steel formworks, a plurality of hole paths are distributed on the cross beams, the edges of the base board are provided with a plurality of draw bar holes, each draw bar hole respectively corresponds to each hole path, a vertical draw bar is arranged between each hole path and each draw bar hole in a penetrating way, both ends of the vertical draw bar are respectively anchored by draw bar nuts, the lower end of each vertical draw bar is connected with a steel wire rope, the other end of the steel wire rope is connected with the top ends of the steel formworks, and the steel side formworks and the steel end formworks are connected by bolts; when the steel-concrete structure hanging box is dismantled, the steel formworks can be dismantled only by dismantling the vertical draw bars and the bolts; for the steel-concrete structure hanging box and a dismantling method thereof, the dismantling of the steel formworks can be realized without the need of underwater operation of a diver, the construction danger is reduced, the dismantling workload is reduced, and the expense investment is reduced while the construction progress is accelerated.

Description

technical field [0001] The invention relates to the field of bridge tie beam construction over water, in particular to a steel-concrete structure hanging box and a removal method thereof. Background technique [0002] At present, the suspension boxes used in the construction of the tie beams of bridges over water are generally steel suspension boxes. Before the construction of the tie beams, the steel suspension boxes are lowered to the pre-designed position to play the role of water-proof construction. Generally, the steel hanging box is composed of the bottom plate, side formwork on both sides and end formwork at both ends. The formwork is connected by bolts. Formwork, the connecting bolts of the bottom plate, and then remove the side formwork and end formwork, but the underwater dismantling workload is large, the strength is high, the danger is high in the construction process of divers, and the efficiency is low; and the bottom plate cannot be removed, and the steel bott...
