System for connecting precast concrete slabs together

Abstract

Abstract PRECAST CONCRETE SLABS OF A BUILDING ARE CONNECTED TOGETHER WITH COAXIAL TENSIONED RODS EXTENDING THROUGH ALIGNED, ELONGATED BORES, RUNNING BETWEEN EDGES OF THE SLABS. IN ONE OF THE SLABS A CUT-OUT IS PROVIDED ALONG ONE OF THE EDGES TO RECEIVE ONE CONNECTOR HALF FIXEDLY POSITIONED IN THE SLAB BY TI-BARS. A SECOND CONNECTOR HALF FIXEDLY MOUNTED ON THE OTHER SLABS PROJECTS INTO THE CUTOUT OF THE FIRST SLAB. EACH CONNECTED HALF INCLUDES A BASE HAVING A CENTRALLY LOCATED APERTURE THEREIN FOR ENABLING A TENSIONED ROD TO BE SECURED TO AN OUTER EDGE OF THE BASE. EXTENDING FROM EACH OF THE BASES IS A PAIR OF WALLS HAVING PARALLEL FACES, EACH HAVING A SLOT WITH SLOPING TOP AND BOTTOM EDGES. FACES ON WALLS EXTENDING FROM ONE BASE ARE IN ABUTTING RELATIONSHIP WITH FACES EXTENDING FROM THE OTHER BASE, WITH MATING SLOTS IN THE FACES FORMING AN ENCLOSED GROOVE. A WEDGE HAVING SLOPING TOP AND BOTTOM SURFACES FITS INTO EACH OF THE GROOVES TO FORM CAMMING SURFACES SECURING THE TWO CONNECTOR HALVES TOGETHER. TO PREVENT LATERAL MOVEMENT OF THE CONNECTOR HALVES, ON ONE OF THE BASES THERE ARE PROVIDED LIPS EXTENDING IN A DIRECTION AT RIGHT ANGLES TO THE BORE AND LONGITUDINAL AXES OF THE WEDGES.
