Claims

[Scope of Claim for Utility Model Registration] (1) A panel of the main body of the formwork is provided with a large number of thin perforations in a scattered manner, and a synthetic resin non-woven fabric or woven fabric is bonded to the surface of the panel without clogging the perforations. Characteristic formwork for concrete forming. (2) The formwork for concrete molding according to claim 1, wherein the woven fabric is a woven fabric whose warp and warp threads are monofilaments. (3) The panel of the formwork body is made of wood, and in order to join the woven fabric to the panel, a web-like or mesh-like hot melt adhesive sheet made of heat-melting synthetic resin fibers is placed between the panel and the woven fabric. A formwork for forming concrete according to claim 1 or 2, characterized in that the formwork is interposed and thermally welded. (4) Claim No. 1 for utility model registration, which is characterized in that the surface of the woven fabric is calendered.
A formwork for forming concrete according to items 1 to 3.
