Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method for a thin arch-shaped cement extrusion molded plate which can support load without using timbering. SOLUTION: Two sheets of an iron plate 2 are serially laid on a tray 1, and on the iron plates 2, a mixed and kneaded cement mortar 3 is continuously extruded. The cement mortar 3 is cut at the joint of the iron plates 2, and respective iron plates 2 are separated from the tray 1. Then, respective iron plates 2 are mounted in parallel on a mold 4 which is formed into an arch-shape. After hardening them by a steam curing and an autoclave curing, they are cut. Thus, this cement extrusion-molded plate of a specified length is formed.
