摘要： PURPOSE:To permit the centrifugal production of a cover by a method in which a partition formwork is interposed through a section profile between the adjacent molding plates of a formwork unit, after placing a hardening material, the hardening material and fibers are supplied while turning the formwork unit, and the molded object is removed and cut at a specific position. CONSTITUTION:A split cylinder-type formwork unit 4, consisting of a flange side, outer molding plates 1 and 2, and connecting metals 3, is set, where the metal tools 3 and a partition formwork 5 are connected with bolts 6 and the formwork 5 is interposed through a section profile 7 forming bolt holes between the adjacent molding plates 1. A hardening (with time) material 8 for flange is packed into the space formed by the formwork 5 and the molding plates 1 and compacted while turning the unit 4 and its supporter. While further turning the unit 4, the hardening (with time) material for cover and fibers are supplied and hardened, and the molded object is removed. The bolt 6 is removed away to separate the formwork 5, and the molded groove bottom is cut off by cutter.

摘要： PURPOSE: To facilitate construction by vertically standing a longitudinal plate standard part being plane at least in its outer face and pilaster part precast concrete members so as to be formed in the similar cylinders, and straining PC steel wire disposed in the circumferential direction. CONSTITUTION: Precast concrete members 3a, 3b of a standard part and pilaster part are formed respectively into a flat in its outer face and an arcuate face in its inner face, and then it is formed such that the outer face of a tank becomes a polygonal shape and the inner face thereof leads to be a cylindrical shape during assembly. In addition, each member 3a, 3b has arcuate sheathes 7 horizontally buried therein at predetermined distances in the vertical direction, and formed on the member 3b is a bearing plate for fastening the end parts of PC steel wire. Furthermore, a plurality of members 3a are set upright via an elastic sealing material or the like among the members 3b set upright at predetermined distances, and the PC steel wire is inserted into the sheathes to thereafter be fastened to the bearing plate, and then the PC steel wire is trained to introduce prestress therein.
