Permanent form for precast tilt-up concrete modules and process

Abstract

Abstract A SPECIAL PERMANENT FORM MEMBER SERVES AS THE FORM FOR A PRECAST TILT-UP CONCRETE PRODULE AS IT IS POURED ON A CURING FLOOR. THE FORM MEMBER REMAINS IN PLACE DURING TILT-UP AND SERVES AS A JOINT AGAINST THE PILASTER. THE FORM MEMBER SERVES AS THE CONCRETE MODULE FORM AND AS THE FINISHED CONCRETE MODULE EDGE AND IS FORMED WITH A PLURALITY OF WEBS WHICH EXTEND ALONG THE EDGE OF THE CONCRETE MODULE. THE EDGES OF THE FORM MEMBER ARE FOLDED IN TO BE LOCKED INTO THE CONCRETE OF THE PRECAST MODULE. THE FORM MEMBER IS USED AS A FORM FOR THE SIDES, TOP AND BOTTOM OF THE CONCRETE MODULE. KNOCKOUTS ARE PROVIDED FOR TRANSVERSE REINFORCING BARS SO THAT THE FORM MEMBERS CAN BE CLAMPED IN PLACE TO RESIST POURING DEFORMATION AND THE REBARS EXTEND INTO THE PILASTERS WHEN THE FINISHED CONCRETE MODULES ARE ARE ERECTED. REINFORCEMENT OF THE TOP AND BOTTOM FORM MEMBERS IS MANAGED BY EXTERIOR STRONGBACKS. CORNERS ARE EMPLOYED ON THE CURING FLOOR TO AID IN INITIAL SETUP. SPECIAL REBAR CLAMPS ARE PREFERABLY EMPLOYED TO TRANSFER POURING LOAD TO THE REBARS. BY EMPLOYMENT OF THE PERMANENT FORM MEMBER, FORMS CAN BE MORE QUICKLY PRODUCED, PRECAST TILT-UP CONCRETE MODULES CAN BE MORE CLOSELY SPACED UPON THE POURING FLOOR, AND CLEANUP MINIMIZED FOR A QUICKER SETUP INTO BUILDING CONFIGURATION.
