Abstract
Precast Building Construction System A building construction system uses precast concrete panels (10) interconnected in an array to provide both floor and ceiling of a multi-unit building. Each panel has a reinforced precast concrete slab having an upper surface (12) and downstands (18, 20) providing a continuous enclosure beneath the floor surface. Grooved voids (44, 58) are preformed into the upper and lower surface of the downstands for receiving connectors (54, 56, 57 or 60, 62, 66 and 50, 52) for connecting adjacent panels. Preformed recesses (19) are provided at the edges of the panel for connecting the panels together and creating grouted shear keys (59).
Claims10
A precast concrete floor panel suitable for being interconnected and supported on a wall or column in a multi-story building, comprising a reinforced precast concrete slab (10), having a substantially flat upper floor surface (12), and integral downstands (18, 20) at or adjacent a perimeter of the panel, the downstands providing a continuous enclosure beneath the floor surface, wherein voids (44, 58) are preformed into the upper and lower surface of the downstands for receiving connectors (54, 56, 57 or 60, 62, 66 and 50, 52) for connecting adjacent panels, and longitudinal recesses (19) are formed in the outer vertical downstand faces so that abutting recesses create a shear key void (59) that can be grouted after assembly to form grouted shear key joints, such that where connected adjacent downstands create integral beams and enable interconnected panels to transmit vertical loads to walls or columns only.
