Purpose of the Invention The conventional method was to lift water, etc. to the inner surface side using centrifugal force and compact it. The purpose is to shorten the molding time by discharging the material through slits formed in the mold.

Structure of the Invention As shown in the drawings, the present invention includes an appropriate number of trough-like frames 1 with their openings facing outward, slits 2 at their joints to form a cylinder, and the outer periphery of the cylinder being tightened with a band 3. A formwork made of a strong thin cloth or paper 4 pasted to the inner surface of the cylinder that allows only moisture to pass through is rotated on rollers, and ready-mixed concrete is poured into the cylinder, and in the process of compaction by centrifugal force, moisture is removed through slits 2. This relates to a configuration characterized in that the molding time is shortened by discharging the molded material to the outside.

る。(Example) This relates to a method for manufacturing a 90 cm concrete plate A. Formwork B is installed so that part of the concrete plate A is in contact with two required slits formed on the inner surface of a formwork with a diameter of 2.3 m, and the roller When fresh concrete is poured in while rotating on the concrete plate, the moisture in the concrete plate A is discharged to the outside through the slits 2 due to centrifugal force, so that the concrete plate A can be compacted quickly.

出することがない等各有益な発明である。C. Effects of the Invention The present invention is constructed as described above, and since the formwork is formed of the trough-like frame 1, the slits 2 can be easily formed at the joints of the trough-like frame 1. Since the mold of the present invention rotates on the rollers and feeds the fresh concrete, the centrifugal force removes excess water in the fresh concrete through the slits 2.
Since it is discharged more quickly, the time required to form concrete products such as concrete plates and cylinders can be shortened. In addition, since the slit 2 is covered with water-permeable fine cloth or paper, mortar will not flow out from the slit 2, which is another advantageous invention.

形方法。1 A suitable number of gutter-like frames have their openings facing outward, slits are provided at their joints to form a cylinder, the outer periphery of the cylinder is tightened with a band, and the inner surface of the cylinder is made of strong fine cloth that allows only moisture to pass through. Alternatively, fresh concrete is introduced while rotating a formwork made of paper pasted on rollers, and in the process of compacting by centrifugal force, water is discharged outside through the slits to shorten the molding time. Centrifugal force forming method for concrete products.
