The house system adopts the lightweight concrete, the lightweight material has more excellent heat preservation, heat insulation, sound insulation and other performances, the cost of the foundation and the foundation is lower, and because the lightweight wallboard and the floor slab have excellent stress performance, the thickness required by the wallboard and the floor slab is smaller on the premise of meeting the stress requirement, the use area of the house can be increased, and compared with the traditional house structure, the use area can be increased by about 5 percent. The used plate can be industrially, commercially and standardly produced and stored.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
