According to the above-described conventional method for producing a columnar molded article made of fiber reinforced cement, since the joint between the divided pieces appears on the outer peripheral surface of the completed columnar molded article, it is aesthetically pleasing. At the same time, there is a problem that it is not preferable, and at the same time, it takes time and effort to form the divided pieces separately and bond them. Further, since the divided pieces are formed by joining them, there is a risk that the strength as a whole is lowered.

However, in order to perform centrifugal molding, a certain degree of fluidity is required for the fiber-reinforced cement fluid because the fiber-reinforced cement fluid is poured into the rotating mold so that it follows the inner peripheral surface of the mold. Becomes However, since fiber-reinforced cement fluid mixes fibers into the cement fluid for reinforcement, the columnar molded product will have higher strength if the length of the fiber pieces to be mixed is somewhat longer, but the fluidity is poor. On the other hand, if a short piece of fiber is mixed, the fluidity improves, but since it has the property of low strength, in order to carry out centrifugal molding, a short piece of fiber is inevitably used. There is a problem that high strength cannot be expected for columnar molded products.

According to the characteristic means of the method for producing a columnar molded article made of fiber reinforced cement in the present invention, the fibers are arranged by arranging the pipes whose axial centers are aligned with each other in the columnar molded article forming space in the mold. Since the reinforced cement fluid is poured into the forming space, the weight of the molded product as a whole can be reduced, and if a high-strength pipe is used, for example, it has a higher strength than a columnar molded product in which a core material such as Styrofoam is embedded. Since the pipe is fixed to the form, the pipe is displaced or lifted by buoyancy as the fiber-reinforced cement fluid is poured into the forming space. This makes it possible to integrally form the columnar molded article at a predetermined portion inside the columnar molded article with the pipe being stably arranged.
Furthermore, since it can be integrally formed, it is possible to form a homogeneous and highly aesthetically shaped molded product without any joint in the columnar molded product.
