<p>A form member (20) comprises a strip-shaped main plate portion (21), which is flat at least on its front surface, a horizontal pair of strip-shaped side plate portions (22a, 22b) extending from both sides of the main plate portion (21) toward its rear surface perpendicularly to the main plate portion (21), and a reinforcing plate (23a, 23b) provided to extend from the rear surface of the main plate portion (21) substantially in parallel with the horizontal pair of side plate portions (22a, 22b). Each of the side plate portions (22a, 22b) and the reinforcing plate (23a, 23b) includes an enlarged end portion (25a, 25b, 26a, 26b) over a prescribed width from its opening end. An end plate body (30) having an engaging portion (32) of a shape for tightly engaging with an end of the form member body (20) engages with this end, to form a single form member. A concrete form member reduced in thickness and weight and enabled to suppress inconvenient deformation in concrete placing can be provided due to this structure. <IMAGE></p> |
