Structure of coordinated modular building construction

Claim 1

A modular structure assembled of a plurality of selfsupporting modules made of reinforced concrete, each module having a form of a rectangular tube defined by two walls, a floor slab and a ceiling slab, said structure being composed in a ''''wall beside wall - front end to back end - floor slab over ceiling slab'''' fashion so that adjacent walls create a doubled wall structure and adjacent floor-and ceiling slabs create a doubled floor structure; each said module being imaginarily divided into several equal tubular segments of which the depth is denoted as a segmental depth - SD - ; said modules being composed of structurally interconnected components - walls manufactured as one-piece panels, floor- and ceiling slabs consisting of one or several panels manufactured in widths which are multiples of SD; said components being manufactured substantially as a ribbed slab with one surface flat and opposite surface fluted at least one flute of ceiling slab aligned with a corresponding flute of walls; solid rims being provided at both wall ends in said floor- and ceiling panels; solid rims being provided at bottom of said wall panels; at least two vertical pipes - each provided with a lifting nut welded at top - being embedded in each said wall panel and positioned at uniform distance T from outer side of wall panel and at uniform distance D from wall end or SD line, respectively; vertical reinforcing bars being embedded in each wall panel and positioned generally on rib- and wall thickness centers; both said pipes and bars protruding at wall top and wall bottom to the extent of the thicknEss of the corresponding floor panel or ceiling panel, such protrusions serving as dowels grouted in holes provided in floor panels and ceiling panels in corresponding positions.
