PROBLEM TO BE SOLVED: To provide an assembly type shuttering wherein transportation and other handling properties are made good by enabling assembly and decomposition to be carried out, and a plurality of cemented excelsior boards and concrete block products which have different sizes can be easily and accurately manufactured. SOLUTION: Four pieces of support bodies wherein a vertical guide groove and an engaging projected line part provided over all length to rectangular two surfaces, are detachably, so that a clearance between adjacent support bodies can be adjusted, disposed on a forming base board. A shuttering board having a specific height capable of adjusting a length according to the clearance between the adjacent support bodies is fitted between the support bodies by inserting its both end parts into the vertical guide grooves and engaging an engaging part comprising a line groove provided on an outer surface of the end part therewith, and a forming space part is formed on the forming base board enclosed by those four side shuttering boards. Further, an intermediate base board is arranged on the forming space part, and an upper stage forming space part is formed by arranging the shuttering board between the adjacent support bodies in the same way as the above.
