APPARATUS AND METHOD FOR SUPPORTING CONCRETE BEAMS, WALLS AND THE LIKE

摘要

A completely closed and reinforced box-like structure for forming a void are a in a concrete formation is constructed of a flat sheet that is scored with a plurality of parallel crease lines and features a side edge reinforcing panel. The reinforcing panel has a plurality of slots thereon. A plurality of interior and end pieces are slit scored so that they may be folded to provide interior and end support units. The suppo rt units define a plurality of spaced apart partitions having a plurality of slots an d flat support surfaces thereon. The structure is assembled by initially folding the side edge reinforcing panel into a position generally normal to the flat sheet to defi ne a longitudinal rib. The support units are then attached to the longitudinal ri b by registering the slots in the partitions in interlocking relationship with corresponding slots on the rib. The support units are then rolled over to fold remaining panels of the sheet along the crease lines in wrapping relation around the support units and thu s, the flat support surfaces. As a result, an enclosure with an interior chamber is defined wherein each of the support partitions substantially fills the cross-sectional area of the interior chamber and the flat support surfaces abut the enclosure. A pair of end pane ls cover the enclosure end openings so that the box-like structure is completely closed.< /SDOAB>
