Claim:
A pre-stressed multi-stemmed concrete floor manufacture station for allowing a user to make a pre-stressed multi-stemmed concrete floor in a safe and efficient manner, comprising, in combination: a multi-stemmed concrete floor form table having a front end with an open front face and a rear end with an open rear face and two parallel side surfaces and a bottom surface and a long axis, with the bottom surface having a plurality of downward projecting troughs, the troughs running the length of the table and meeting the front and rear open faces, with the downward projecting troughs being the molding walls for the formation of the downward projections of a multi-stemmed floor, also known as stems, the front and rear faces allowing the passage of a plurality of pairs of stressing cable holes there through; a pair of trolley rails located on the front and rear end of the multi-stemmed concrete floor form table, the rails lying in line with the long axis of the multi-stemmed concrete floor form table and running up to the front surface and rear surface of the multi-stemmed concrete floor form table; a pair of removable stressing head trolleys with each removable stressing head trolley having a plurality of rail wheels being mated with and received by the trolley rails, each removable stressing head trolley having a front face with a recess being a contact surface and a rear face being a non-contact surface and two parallel side surfaces and a bottom surface, each removable stressing head trolley comprising a stressing block having a first weight, the stressing block having a plurality of pairs of stressing cable apertures there through for receiving and containing a stressing cable, each removable stressing head trolley also having a plurality of stressing cable lock-downs, the lock-downs being coupleable to the stressing cable and coupleable to the trolley to prevent the removal of the stressing cable from within the cable apertures; a removable stressing head coupled to each of the trolleys with each stressing head having a plurality of cable passageways there through, each stressing head also having a front flat surface nested within the front surface recess of each of the stressing head trolleys, the front flat surface coupling with a form table to form a diaphragm header trough, each stressing head also comprising a compressible filler assembly, the filler allowing the multi-stemmed concrete floor to shrink when put in compression by the stressing strands; at least one cable jack having a stressing cable recipient aperture there through, with the cable jack having a stressing cable pulling and tensing means for placing a predetermined amount of tension in a cable.
