Problems solved by technology

The autoclaved lightweight aerated concrete (ALC) floor slab adopted in Japan can greatly reduce the weight of the structure and has better use functions, but this kind of floor slab is relatively thick and is mainly used for low-rise steel structure residences

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 with figure 2 As shown, the composite floor of the present invention includes cold-formed thin-walled steel skeleton 1, autoclaved aerated concrete slab 2, steel mesh 3, lightweight concrete 4 and facing layer 5, and cold-formed thin-walled steel skeleton 1 passes through the process. The font-shaped rib beams 8 form a grid shape, and the autoclaved aerated concrete slab 2 is embedded between the adjacent I-shaped rib beams 8 of the cold-formed thin-walled steel skeleton 1, and the autoclaved aerated concrete slab 2 and the I-shaped rib beams The lower flange of 8 is fixedly connected by self-tapping screws 11; the reinforcement mesh 3 is located above the autoclaved aerated concrete slab 2, and is integrated with the lightweight concrete 4; above, and connected to the upper flange of the I-shaped rib beam 8 by self-t...

Abstract

The invention discloses a cold-formed thin-walled steel composite floor and a modular prefabricated assembly method thereof. The composite floor includes a cold-formed thin-walled steel skeleton, an autoclaved aerated concrete slab, steel mesh, lightweight concrete and decorative surfaces layer, the cold-formed thin-walled steel skeleton is grid-like, and the autoclaved aerated concrete slab is embedded in the grid of the cold-formed thin-walled steel skeleton, and is fixedly connected with the cold-formed thin-walled steel skeleton; The top of the concrete slab is integrated with the lightweight concrete; the finishing layer is set on the upper surface of the lightweight concrete and fixedly connected with the cold-formed thin-walled steel skeleton. The composite floor has the excellent performance of clear and reasonable force transmission, can meet the requirement of large span, is easy to divide the space flexibly, and adapts to the requirements of the residential market. The assembling method of the present invention has the advantages of simple procedure, fast speed and good integrity, is beneficial to realize building energy saving, and facilitates the industrialized production and modular construction of cold-formed thin-walled steel structure, a green building.

Description

technical field [0001] The invention relates to a multi-layer cold-formed thin-walled steel residential structure, in particular to a cold-formed thin-walled steel composite floor and a modular prefabricated assembly method thereof. Background technique [0002] Over the years, cold-formed steel structures have been widely used in low-rise residential buildings and small industrial buildings abroad due to their advantages of light weight, easy forming, environmental protection and recyclability, and are expanding to multi-storey buildings. my country has introduced a large number of low-rise cold-formed steel structure residential technologies from abroad. Up to now, cold-formed steel structures are mainly used in buildings below three floors. Due to the large population, tight land resources, and severe earthquake disasters, it is more in line with my country's national conditions to develop cold-formed thin-walled steel structure residences from low-rise to multi-storey. ...
