    • PROBLEM TO BE SOLVED: To isolate placed concrete from the outside atmosphere, and prevent incursion of rainwater, dissipation of hardening heat and generation between upper and lower temperature differences by direct sunlight by attaching a cover to the upper end of a form for foundation concrete preparation. SOLUTION: A foundation top end curing material is formed of a resin-made thin plate, and sandwiching pieces 6, 6 formed on both the sides of a projection- like curved cover part 5 are press-fitted on a form by elastic deformation to be attached. Even in the case where the width of the form 7 is slightly increased and decreased, the curvature of a curvature part 5 is changed, so that attaching is enabled. Curing materials corresponding to respective shapes are used for an angular part in which foundation concrete is bent in L-shape, a part intersected in T-shape and another part intersected in X-shape. Thereby during the placed concrete is hardened, incursion of rainwater is prevented, at cold time the hardening heat of concrete is prevented from being dissipated to promote hardening, at intense heat time a temperature difference between upper and lower parts is produced by direct sunlight, and production of partial cracking can be prevented.
