Abstract

A light-weight formwork having a small change in dimensions due to an environmental temperature. A foundation formwork includes a metal frame having a rectangular frame shape, and a resin faceplate attached to the metal frame and closing an opening of the metal frame. The metal frame includes a top plate having fitting notches and L-shaped bridged bodies. The resin faceplate includes protruding bodies fitted with the fitting notches and L-shaped slits into which the bridged bodies are fittingly inserted. The protruding bodies fit with the fitting notches and the bridged bodies are fittingly inserted into the slits, thereby the resin faceplate is attached to the metal frame. The attached resin faceplate closes an opening of the metal frame. The fitting notches and the bridged bodies suppress an expansion and contraction of the resin faceplate in a left and right direction.
