METHOD FOR FORMING CONCRETE BUILDING AND FORM DEVICE

PROBLEM TO BE SOLVED: To provide a method with which a concrete building in a bank shape including a continuous protrusion in an upper part can be easily constructed and the protrusion can be constructed beautifully in a predetermined shape, and a form device.SOLUTION: A form device 1 is disposed with a planar plate 2 located along one side face continued to a portion to form a protrusion 15 of a concrete building, and used while being provided in parallel along a length direction of the concrete building. In that case, a form panel 17 to be assembled so as to form the protrusion 15 with the form device 1 is assembled in such a manner that an edge 19a of a panel surface 19 is positioned in a middle height of an opening 11 for concrete introduction that is opened in the form device 1. Concrete is introduced from the inside of a hopper section 7 through the opening 11 into a form, and the concrete is solidified in the state where a first opening/closing plate 8 is inserted from an upper side and the opening 11 is closed. On the other hand, a second opening/closing plate 12 is pulled out and residual concrete within the hopper section 7 is discharged.
