Abstract
A method of construction in which a plurality of vertical columns are cast on a base, the columns being arranged at the vertices of contiguous, congruent, equilateral triangles. A roof slab is then cast on the base, the roof slab having apertures through which the columns pass. Reinforcing mats give rise to a plurality of reinforced zones arranged in a pattern which reproduces the pattern of apertures are cast into the slab. The pattern of zones is displaced 60.degree. with respect to the pattern of apertures. Subsequently the slab is raised, preferably by flotation, until it is clear of the columns, and then turned through 60.degree. so that the reinforced zones lie above the columns. Thereafter, the roof slab is lowered onto the columns.
Claims2
A method of erecting a roof slab, comprising casting a plurality of structural support columns at the vertices of contiguous, congruent, equilateral triangles, the columns extending upwardly from a base, and casting a roof slab on said base, the columns passing upwardly through apertures in the slab, the roof slab being cast with a plurality of reinforced zones the centres of which are at the vertices of contiguous, congruent, triangles, the plurality of reinforced zones being arranged in a pattern reproducing the pattern of apertures but displaced circumferentially with respect thereto, lifting the roof slab with respect to the base until it is clear of the columns, rotating the roof slab until each reinforced zone is above one of the columns, and lowering the roof slab onto the columns.
