Divider for light-weight aggregate balcony floors

Abstract

Abstract A DIVIDER FOR LIGHT-WEIGHT AGGREGATE FLOORS OF THE CLASS HAVING A WOOD SUBSTRATE (SUBFLOOR) COMPRISING A UNITARY EXTENDED METAL STRIP WITH A REFERENCE UPRIGHT AXIS RELATIVE TO THE SUBSTRATE. AN EXAMPLE OF SUCH A FLOOR IS A BALCONY. THE DIVIDER HAS AN ATTACHMENT FLANGE INTENDED TO BE ATTACHED TO THE WOODEN SUBSTRATE AND EXTENDS UPWARDLY FROM THE ATTACHMENT FLANGE SO AS TO INCLUDE IN THE FOLLOWING ORDER FROM THE BASE, A SPACER SEGMENT, A FIRST FLAT RAMP SEGMENT SLOPING AWAY FROM THE SPACER SEGMENT, A CURVED KEY SEGMENT, A SECOND FLAT RAMP SEGMENT, THE FLAT RAMP SEGMENTS FORMING AN OPEN DIHEDRAL BETWEEN THEM FACING TOWARD THE AXIS, AND A FLAT TERMINAL SEGMENT. RADIUS SEGMENTS INTERCONNECT THE PREVIOUSLY RECITED SEGMENTS. THE CURVATURES OF THE VARIOUS RADII AND OF THE KEY SEGMENT MINIMIZE STRESS CONCENTRATIONS IN THE CONCRETE AND THE FLAT RAMP SEGMENTS GIVE GREATER EFFECTIVENESS OF THE DIVIDER OVER THE RELATIVELY LARGE EXPANSIONS AND CONTRACTIONS ENCOUNTERED WITH THE USE OF LIGHT-WEIGHT AGGREGATE. THIS ENABLES A STRAIGHT, ACCURATELY-LOCATED CRACK TO BE FORMED IN THE LIGHT-WEIGHT AGGREGATE WHILE STILL KEYING THE TWO ADJACENT SECTIONS OF AGGREGATE TOGETHER TO PREVENT THEIR VERTICAL SEPARATION.
