Frames for constructing pavement boards

Abstract

The present invention is a frame for constructing pavement boards in which plural sections having the bottom are divided, plural holes for draining water are made in the bottom, plural through holes in the directions of top and bottom are formed at the section walls of the above sections, respectively, the lower sides of the holes are opened and the upper sides of the holes are closed so as to be openable. The upper sides of the above through holes are closed so as to be openable by a thin film which is unitedly formed with the frame or an adhesion tape which is applied to the upper sides of the section walls. Thus, the above frame can be obtained by the process in which concrete or mortar are poured into the sections, after hardening the concrete or the mortar, the upper sides of the through holes are opened by removing a little the upper sides of the section walls, or by stripping off the adhesion tape which is applied to the upper sides of the section walls, so that the frame can be used for producing the permeable pavement boards which are mainly made of concrete or mortar. The water permeability is secured by the above through holes.
