Abstract
A modular panel which may be combined with others to constitute a mold for depositing concrete or the like is disclosed. Each modular panel is corrugated to have ridges and troughs which extend parallel to and alternating with each other. At least the troughs are provided with openings in the form of elongate slots with or without circular holes combined therewith such that the openings define nailing passages in alignment with those of another modular panel which is joined with that panel, with no regard to the relative position of the joined panels. An elastic transparent strip is adhered to the bottom of each trough to cover the openings while allowing nails to be driven therethrough.
Claims11
A modular panel for forming a mold, comprising:
- a plurality of parallel longitudinal ridges and a plurality of parallel longitudinal troughs which extend in a predetermined direction and alternate with each other, said ridges and troughs being connected by walls forming an angle other than an acute angle with said troughs;
- and
- a plurality of elongate openings formed through at least opposite end portions of a bottom of at least each of said troughs, not in parallel with the direction of the trough, but at an angle other than a right angle thereto, and in such a manner that said elongate openings, when aligned with openings of another modular panel define through passages for nails and enable said modular panels to mount substantially flush with one another,
- wherein said elongate openings are disposed in said trough in at least one array wherein those openings of said at least one array located above a transversal centerline of the panel are disposed at angles opposite to those openings located below said centerline.
