Abstract
A flexible form sheet is described, which is used for producing plaster cavity floors. The sheet has regularly distributed, leg-like bulges. The bulges are interconnected by horizontal sheet surfaces. Increased flexibility areas are located between the bulges, and are preferably deformed. They are appropriately constructed as zig-zag or concertina-like strips concentrically surrounding the bulges. This provides an increase in the vertical reciprocal mobility of the bulges, so that on applying the plaster, the form sheet can adapt to unevennesses of the underfloor.
Claims7
A flexible form sheet for use in producing a plaster cavity floor, comprising a sheet with regularly distributed bulges and defined increased flexibility areas between the bulges as a result of a modification to bending behavior of the sheet, wherein the increased flexibility areas are deformed areas concentrically surrounding the bulges.
