Steel bar structure of thick raft and inversion construction method of steel bar structure

Abstract

The invention provides a steel bar structure of a thick raft and an inversion construction method of the steel bar structure. The steel bar structure of the thick raft is composed of multiple raft face ribs, multiple raft bottom ribs, multiple stirrups and a supporting frame. The supporting frame is installed on a raft cushion layer, the multiple raft face ribs are laid on the supporting frame, the multiple stirrups are arranged on the multiple raft face ribs arranged in the same direction in a sleeving manner, the upper portions of the multiple stirrups are arranged on the multiple raft faceribs in a hanging manner, the multiple raft bottom ribs are arranged in the multiple stirrups in a penetrating manner, the lower portions of the multiple stirrups are supported on the multiple raft bottom ribs, the raft bottom ribs are fixedly connected to the lower portions of the stirrups, and the raft face ribs are fixedly connected to the upper portions of the stirrups. The steel bar structuresolves the problems that the use amount of traditional thick raft steel is large, and the cost is high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel bar structure of a thick raft and a reverse construction method thereof. Background technique [0002] As super high-rise buildings become higher and higher, the raft (bottom) of the building becomes thicker and thicker, reaching 3m to 7m locally, and the number of reinforcement layers of the raft (bottom) increases. As the design thickness of the raft becomes larger and larger, the reinforcement arrangement of the raft becomes more unique and dense. Especially when the raft (bottom slab) adopts pile foundation, in order to reduce the uneven settlement of the building and improve the overall stress, the raft (bottom slab) needs to be equipped with bottom ribs, gluten, and crack-resistant distribution ribs. Concealed beam reinforcement is arranged in the middle of the bottom slab, and the force transmitted from the upper structure to the raft (bottom slab) i...
