Abstract
A prefabricated building includes a pre-cast concrete chain wall foundation having upper and lower walls with a height and a thickness, the ratio of wall height to wall thickness being equal to or greater than 3 to 1 and the wall height is at least three (3) feet; and a prefabricated building positioned upon the precast concrete chain wall foundation, wherein the prefabricated building has walls that rest upon the upper surface of the pre-cast concrete chain wall foundation.
Claims15
A prefabricated building, comprising:
- a) a pre-cast concrete chain wall foundation having upper and lower surfaces and walls with a height and a thickness, the ratio of wall height to wall thickness being equal to or greater than 3 to 1 and the wall height is at least three (3) feet, wherein the precast concrete chain wall foundation includes a plurality of corner columns that are integral poured corners not joined by external fasteners, a plurality of intermediate columns, upper and lower spaced apart beams and a plurality of openings that are surrounded by upper and lower beams and columns, and wherein said pre-cast concrete chain wall foundation is not a poured in place foundation;
- b) a prefabricated building positioned upon the upper surface of the precast concrete chain wall foundation,
- c) wherein the prefabricated building has walls that rest upon the upper surface of the pre-cast concrete chain wall foundation.
A prefabricated building installation system for installing a building and foundation upon a selected site, comprising:
- a) a lifting device;
- b) a prefabricated concrete chain wall foundation having multiple planar wall sections and multiple corners, each wall section having a wall height and a wall thickness, the ratio of the wall height to wall thickness being at least 3 to 1, wherein the precast concrete chain wall foundation includes a plurality of corner columns that are integral poured corners not joined by external fasteners, a plurality of intermediate columns, upper and lower spaced apart beams and a plurality of openings that are surrounded by upper and lower beams and columns, and wherein said pre-cast concrete chain wall foundation is not a poured in place foundation;
- c) a prefabricated building having a floor, walls, ceiling and roof;
- d) at least one transporting vehicle that enables transport of the lifting device and the prefabricated concrete chain wall foundation to a selected building site;
- e) rigging that enables the lifting device to transfer the prefabricated concrete chain wall foundation to the selected site and for transfer of the prefabricated building from the transporting vehicle and placement upon the prefabricated concrete chain wall foundation;
- and
- f) the prefabricated concrete chain wall foundation and prefabricated building occupying the selected site which is defined by the positioning generated by the lifting device.
