Abstract

See full text

To prevent a skid panel attached with wear resistance material of porcelain tiles or the like on its surface from warping in a longitudinal direction of laying the skid panel, a warp amount of a skid panel is predictively calculated from shrinkage strain, shrinkage force and upper and lower edge stresses of concrete, reverse camber is provided in the longitudinal direction of a mold of the skid panel with tensioning devices to nullify the final warp amount and concrete is fed to the mold to thereby fabricate the panel.
