2. Description of the Related Art The above-mentioned bay window is provided in, for example, an outer wall on the side of a common corridor or an outer wall on the side of a wife of an apartment house. This bay window is structurally small when viewed from the whole of the housing complex. For example, the overhanging dimension from the outer wall is about 500 mm and the size is about 1500 mm high and about 2000 mm wide on both sides. It has a complicated three-dimensional shape in which a protruding portion (duck portion) toward the side where the window frame is installed is continuously provided at the protruding end of the bay window body.

[0003]

As described above, in order to construct a bay window having a complicated structure that is structurally small and complicated in shape, conventionally, various arrangements have been made so as to cleverly arrange and enclose the bay window. Although the means of on-site construction where a formwork of various shapes was installed and concrete was placed was taken, the work of complicated bar arrangement and the production of a small and enormous number of formwork and this formwork There is a problem in that the installation work and the demolding work are complicated and the construction period is long.

Further, since the shape is complicated and the filling property of concrete is poor, it is necessary to rework by plastering work after the mold is removed, and when the mold is released from the mold, it is small and fragile, so that it is damaged. It was very uneconomical because the number of times the formwork was diverted to construct a bay window on the upper floor was reduced.

An object of the present invention is to make it possible to construct such a window that is structurally small and has a complicated shape in a simple and easy manner and in a short construction period.
