Prefabricating assembling type cold molding steel floor system and construction method thereof

Abstract

The invention discloses a prefabricating assembling type cold molding steel floor system which comprises a keel unit, a rectangular concrete filled steel tube straining beam, a light concrete plate, steel bars with equal length, a heat insulation material layer, lower-layer wall bodies and upper-layer wall bodies. The rectangular concrete filled steel tube straining beam is located between the lower-layer wall bodies and the upper-layer wall bodies and respectively fixedly connected with the lower-layer wall bodies and the upper-layer wall bodies. Two ends of the keel unit are located above the two adjacent low-layer wall bodies, and the keel unit is fixedly connected with the rectangular concrete filled steel tube straining beam. The light concrete plate is located above the keel unit and fixedly connected with the keel unit. The steel bars with equal length penetrate through bar penetration holes on the rectangular concrete filled steel tube straining beam to be located in a plate gap of the light concrete plate. The heat insulation material layer is filled in the keel unit. The steel floor system has the good performance of being explicit and reasonable in stress and force transfer. A construction method of the steel floor system is further disclosed. The system and the method have the advantages of being simple in work procedure and high in speed.

Description

technical field [0001] The invention relates to a multi-layer cold-formed steel residential structure, in particular to a prefabricated assembled cold-formed steel floor and a construction method thereof. Background technique [0002] At present, in the cold-formed steel structure system, the floors commonly used at home and abroad mainly include light steel and wood floors, profiled steel composite floors and cast-in-place concrete composite floors. The light-steel wood floor refers to laying wooden boards on the steel joists, and the wooden boards are provided with very thin cushions, which can be covered with surface layers and carpets. This kind of floor slab is mainly used in the case of small slab span, which has the characteristics of light weight and fast construction speed, but its rigidity is small and the anti-vibration effect is poor. The profiled steel composite floor slab refers to fixing the corrugated board on the surrounding steel joists and pouring lightwe...
