Prefabricated floor slab, detachable steel-concrete composite floor system and construction method thereof

Abstract

The invention discloses a prefabricated floor slab, a detachable steel-concrete composite floor system and a construction method thereof, and relates to the technical field of constructional engineering. The prefabricated floor slab comprises a plurality of prefabricated slabs, reinforcers, a plurality of reinforcing pieces and reinforcing structures, wherein the prefabricated slabs are provided with lap joint sides and shear force sides, the lap joint sides of every two adjacent prefabricated slabs are detachably connected, and the shear force sides of every two adjacent prefabricated slabs are arranged at intervals; the reinforcers are arranged on the end faces of the shear force sides of the prefabricated slabs; the reinforcing pieces are arranged between every two adjacent reinforcers in a penetrating mode, and the plurality of reinforcing pieces are distributed in the vertical direction; and the reinforcing structures are poured between every two adjacent reinforcers. According to the prefabricated floor slab, the reliability in installation and use on a main structure can be guaranteed, and the prefabricated floor slab can be quickly and reliably removed from the main structure for repeated use.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated floor, a detachable steel-concrete composite floor and a construction method thereof. Background technique [0002] At present, the composite floor is widely used in the fields of construction engineering and bridge engineering because of its better mechanical performance and the ability to save engineering costs. The prefabricated composite floor system generally uses wet joints to form a permanent connection with the main structure. Although the combined floor in the prior art has a part of the detachable floor system, the existing detachable floor system generally uses bolts to connect the concrete floor and the steel beam as a whole. When the floor structure is stressed, the bolts usually Accompanied by excessive deformation, subsequent disassembly is difficult or even impossible. [0003] Therefore, need badly a kind of prefabricated floor,...
