[0002] A cantilevered balcony refers to a balcony that extends out in whole or in part, with no load-bearing walls or columns on the outermost side. The load is carried by the floor slab or by beams at both ends of the balcony. When constructing this balcony, a support formwork is required to cast the balcony. After the balcony is cast, the casting formwork is supported by a support device to complete the shaping of the balcony.
