PURPOSE: To resolve shortage of hands by obtaining a large integrated concrete shuttering by a method wherein in a platy concrete shuttering of which vertical and horizontal length and thickness are specific dimensions, the vertical thickness is varied, and a frame along a periphery and a vertical rib are provided on its one side.
CONSTITUTION: A concrete shuttering composed of an integrated crosslinked polymer is obtained by mixing a monomer liquid A and monomer liquid B which consist of metathetically polymerizable cyclic olefin containing respectively metathetical polymerization catalyst based catalytic component and anactivating agent and the mixed solution is poured into a mold to be polymerized and reacted by crosslinking in the mold. Then, the concrete shuttering is rectangular platy material 1 of 1000-3000mm in vertical length (a), 1/2-1/6 the vertical length (a) in a horizontal length (b), and 3-10mm in thickness. The thickness (c) of the platy material 1 varies along the vertical direction, a frame 3 along its periphery is provided on one side of the platy material 1, and a plurality of ribs 2 are provided vertically.
