Claim:
A four-sided reinforced static box frame as a basis for a building, comprising: a rectangular floor portion comprising a first plurality of parallel joists each spaced apart from adjacent joists of the floor portion by a common first dimension; a first wall portion comprising a second plurality of parallel joists each spaced apart from adjacent joists of the first wall portion by the common first dimension; a ceiling portion comprising a third plurality of parallel joists each spaced apart from adjacent joists of the ceiling portion by the common first dimension; and a second wall portion comprising a fourth plurality of parallel joists each spaced apart from adjacent joists of the second wall portion by the common first dimension; wherein the floor portion is joined to the first wall portion at a first reinforced intersection at a right angle with ends of the joists of the floor portion alternated with ends of the joists of the first wall portion, the alternated joists of the floor portion and the joists of the first wall portion joined by a torsion locking block exactly filling the space between each alternated joist, and wherein a locking bar or cable passes through the joined joists and locking blocks, and a tensioning mechanism tensions the bar or cable, compressing the reinforced intersection, and wherein a second reinforced intersection is formed at a right angle between the first wall portion and the ceiling portion, a third reinforced intersection is formed at a right angle between the ceiling portion and the second wall portion, and a fourth reinforced intersection is formed at a right angle between the second wall portion and the floor portion, in the same manner is the first reinforced intersection is formed, completing the reinforced four-sided box frame.
