发明名称 Premanufactured portable concrete house
摘要 This invention provides a premanufactured portable concrete house and efficient systems for making such a house and for providing portability to a housing site. Floor, roof, and wall components are made by casting concrete in molds with features such as electrical and water conduits being concrete-embedded during the casting. Also concrete-embedded in the various house components are steel plates used for welding to secure the components to each other during assembly of a portable house. Spaced core holes for holding lift rods are cast into the periphery of the floor/foundation component; and these are used as lift points in lifting the house onto a truck for transport to a housing site.
