Abstract

725,132. Shuttering for casting concrete. RAPID METAL DEVELOPMENTS, Ltd. Oct. 31, 1951 [Nov. 1, 1950], No. 26620/50. Class 20 (2). [Also in Group XXII] A shuttering panel for use in building concrete structures is formed from rectangular steel sheet 1 by raising the boundaries of the sheet to form flanges 2 disposed by a few degrees at less than a right angle to the body of the sheet. The flanges are provided with regularly spaced slots 3 and the edges 7 of the flanges are welded together. The radiused edges 10 of the panel are rendered perpendicular by cold forging (see Group XXII) so that when a series of panels are clamped together a smooth surface is presented and the formation of ribs or beads on the concrete structure caused by radiused edges is prevented. Specifications 682,870 and 725,135 are referred to.
