Concrete structure with combination compression and tension reinforcement splices

Claim 1

IN COMBINATION WITH A CONCRETE BODY, A METAL REINFORCEMENT EMBEDDED THEREIN INCLUDING TWO REINFORCEMENT BARS EACH HAVING PLURAL PROJECTING DEFORMATION RIBS SPACED APART LENGTHWISE THEREOF AND DEFINING MULTIPLE INTERVENING CHANNELS HAVING RADIALLY EXTENDING SIDE WALLS CONSTITUTING ABUTMENT FACES, AND SPLICE MEANS CONNECTING THE BARS TOGETHER IN END-TO-END RELATION, SAID SPLIC MEANS COMPRISING A CONTRACTIBLE SLEEVE EMBRACING AND GRIPPING THE ADJACENT ENDS OF BOTH BARS AND HAVING A LENGTH SUFFICIENT TO ENCOMPASS A SERIES OF SAID RIBS AND INTERVENING CHANNELS AT THE END OF EACH BAR, SAID SLEEVE HAVING A PLURALITY OF SIDE OPENINGS OF DIMENSIONS GENERALLY COMPARABLE TO SAID CHANNELS, SAID OPENINGS BEING DISTRIBUTED THROUGHOUT THE LENGTH AND CIRCUMFERENCE OF THE SLEEVE AND CONSTITUTING PASSAGEWAYS FOR ADMITTING CONCRETE GROUT INTO SAID CHANNELS DURING POURING OF SAID CONCRETE BODY TO THEREBY AFFORD A CORRESPONDING PLURALITY OF APPENDANT CONCRETE INTERLOCK SEGMENTS EXTENDING FROM THE MAIN CONCRETE BODY THROUGH THE SLEEVE WALL INTO THE SLEEVE AND INTERLOCKING THE ABUTMENT FACES ON THE BAR DEFORMATION RIBS WITH THE INTERNAL SURFACES OF THE SLEEVE APERTURES, SAID INTERLOCK SEGMENTS SERVING TO TRANSMIT BOTH COMPRESSION AND TENSION FORCES FROM ONE BAR TO THE OTHER THROUGH THE SLEEVE, SAID SIDE OPENINGS BEING DISTRIBUTED LONGITUDINALLY AND CIRCUMFERENTIALLY THROUGHOUT SAID SLEEVE TO ASSURE COMPLETE PERIPHERAL INTERLOCKING OF THE SLEEVE WITH BOTH BARS.
