The invention discloses a composite cored slab house and a building method thereof, belonging to the field of woolen frame
structure building construction. The house is formed by combining basic rooms, each of which is composed of a structural
support system and a plate body, wherein, for each basic room structural
support system,, a corner post, a central pillar, a cross beam and a
purlin form a two-layer woolen frame
system; a
gable vertical frame is transversely embedded with a composite cored slab; a front vertical frame and a rear vertical frame along walls are vertically embedded with the composite cored slab, a door and a window; a grillage along the horizontal direction is respectively laid with the composite cored slab to form a floor
system; and a grillage at the upper part is laid with the composite cored slab to form a roofing
system. All the components of the invention can realize normalization,
standardization and industrialization; the quality can be effectively ensured, and the cost can be reduced; various types of low-rise buildings can be designed and built according to the building requirements of the owners. The composite cored slab house is light in installation, rapid in construction speed, short in period as well as simple and convenient in
assembly and disassembly, can be recycled for a plurality of times, is separated flexibly, and is easy to change for recycling.
