取り付けられていることを特徴とする型枠装置。 A formwork device having three sets of primary formworks for product molding each vertically divided into thirds, each of the primary formworks being placed at the apex of an imaginary equilateral triangle on the same plane when the mold is closed. The mold is provided with a central holding form for placement in an upright form and a secondary form surrounding the central holding form, and the secondary form is capable of opening in the normal direction of each side of the virtual equilateral triangle. The dividing line of the secondary formwork coincides with the dividing line of each of the primary formworks, and one of the divided molds of each primary formwork is divided into three parts at the center. A formwork device characterized in that the holding formwork side is attached to the other two formwork sides, and the other two are attached to the secondary formwork side.
