Abstract
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.
Claims13
A premanufactured portable concrete housing structure comprising, in combination:
- a. first concrete means for providing a floor member;
- b. multiple second concrete means for providing wall members;
- c. third concrete means for providing a roof member;
- and
- d. said first concrete means comprising multiple spaced means for assisting lifting and deposit of said premanufactured portable concrete housing structure;
- e. wherein each of said multiple spaced means for assisting lifting and deposit of said premanufactured portable concrete housing structure comprises core means adjacent a side of said first concrete means;
- f. wherein said core means comprises a horizontal hole substantially perpendicular to said side of said first concrete means;
- and
- g. wherein said core means comprises a substantially-cylindrical hole, in a socket beam, adapted for holding a substantially cylindrical rod member adapted for jacking.
A premanufactured portable concrete housing structure comprising, in combination:
- a. first concrete means for providing a floor member;
- b. multiple second concrete means for providing wall members;
- c. third concrete means for providing a roof member;
- and
- d. said first concrete means comprising multiple spaced means for assisting lifting and deposit of said premanufactured portable concrete housing structure;
- e. wherein said first and second concrete means comprise concrete-embedded first attachment means for attaching said first concrete means to each of said second concrete means;
- and
- f. wherein each said first attachment means comprises first steel plate means for welding to an other said first attachment means.
A premanufactured portable concrete housing structure comprising, in combination:
- a. first concrete means for providing a floor member;
- b. multiple second concrete means for providing wall members;
- c. third concrete means for providing a roof member;
- and
- d. said first concrete means comprising multiple spaced means for assisting lifting and deposit of said premanufactured portable concrete housing structure;
- e. wherein said third concrete means comprises a pair of said roof members connected at a selected pitch by connection means comprising concrete-embedded second steel-plate means for welding to an other said connection means.
A premanufactured portable concrete housing structure system, using housing structure members formed as floor members, roof members, and wall members for connection to provide a premanufactured portable concrete housing structure, comprising the steps of:
- a. preparing a horizontal concrete-casting mold for casting a concrete means for providing a said housing structure member;
- b. placing into said mold internal steel rebar elements for said concrete means and surface steel plate elements for said concrete means, each said surface steel plate element being supported by dowel means supported by a said steel rebar element;
- c. placing concrete into said mold and curing said concrete to provide a solid said housing structure member;
- d. removing said housing structure member from said mold;
- e. from the above steps, using suitable said concrete-casting molds, accumulating said housing structure members, formed as floor members, roof members, and wall members;
- f. from said accumulated said housing structure members, making a premanufactured portable concrete housing structure by successively
- i. placing each said housing structure member in suitable juxtaposition to an other said housing structure member, and
- ii. welding together contacting said surface steel plate elements of said juxtaposed housing structure members;
- g. transporting said premanufactured portable concrete housing structure to a suitable site;
- and
- h. depositing said premanufactured portable concrete housing structure on said site.
A premanufactured portable ready-to-use concrete house comprising:
- i. a precast concrete floor member comprising bottom portion concrete beams for added support strength, said concrete beams comprising both circumferential beams and internal beams;
- j. four precast concrete exterior wall members;
- k. two precast concrete roof members each supported by three of said wall members at a pitch angle;
- l. an interior bearing wall member further supporting said roof members;
- and
- m. concrete-embedded attachment means in each of said members (said floor member, said exterior wall members, said roof members, and said interior bearing wall member), attaching each said member to a juxtaposed other member;
- n. wherein each said attachment means in each said member comprises a steel plate welded to an other said attachment means of an other said member.
