Fromwork panel

Abstract

[Problem to be Solved] The present invention is a formwork panel which can be utilized as an ordinary flat plate-shaped formwork and is further provided with excellent flexibility of design for forming a corner portion for a formwork when the formwork panel is utilized as the corner portion and prevents concrete or mortal from leaking from an unintended position. [Solving Means] A formwork panel 1 is a formwork panel of an implanted type formed by bending a plate-shaped material made from steel to an approximately rectangular shape in front view and an approximately squared wave shape in sectional view and cutting the same. By bending the panel steel plate to an approximately squared wave shape, a plurality of ridges 11 parallel with one another is formed on the formwork panel 1 at a predetermined interval. A plurality of projection-shaped ribs 12 in section in a widthwise direction is formed between the respective ridges 11 in parallel with the ridges 11 in a repetitive manner at a predetermined interval. Further, cuts 13 with a predetermined length are provided on both ends of the ridge 11 in a panel widthwise direction in parallel with the ridge 11 at a predetermined interval in a dashed manner.
