Prefabricated self-supporting modular room elements

Claim 1

A building formed from plural precast, inter-connected elements in which said elements are adapted to be oriented into a plurality of configurations comprising: a first element having edges defined by a substantially inverted "U" shaped configuration including vertical legs and a planar top portion canted relative to a horizontal plane whereby a plan view of either of said vertical legs would define a trapezoid and means along the edges thereof to fasten said first element further including a second element having edges defined by a substantially inverted "L" shaped configuration including one vertical leg and one horizontal leg having means along the edges thereof to fasten said second element to another element including a third element having edges defined by a parallelepiped box shape, open along its top extent, having a door-type passageway on a first vertical wall, second and third opposed walls orthogonally fastened to said first wall, and a fourth wall facing said last named wall wherein said second and third walls extend beyond said first and fourth walls thereby providing an outwardly extending sheath, and means along the edges to fasten said third element to another element wherein said means along the edges to fasten said elements includes a recess along said edge, and an iron bar extending into said recess from one wall's edge of said element, said iron bar forming a loop in said recess and extending back into said one wall's edge and in which a first set of two of said elements have their recesses in registry whereby their respective loops overlap further including a tying bar extending through said loops and said recesses are filled with cementitious material and wherein said first set of elements is fastened to a supporting base through stirrup means, in which said stirrup means is defined by a pair of U-shaped elements embedded in said base and extends upwardly therefrom facing each other such that an open area of each U stirrup faces away from each other and a wall of an element is affixed therebetween.
