[0003]

However, in the above-mentioned prior art, when the opening is provided at the projecting corner, the projecting outer corner panel between the two surfaces and the opening outer wall panel forming the projecting corner is formed. Because it consists of a corner panel,
An upper horizontal member and a lower horizontal member that are laid in the lateral direction are formed by being divided into an opening panel and a projecting corner panel having these two surfaces. The opening frame of the projected corner divided in this way is complicated.

Further, when the width of the opening becomes large, the opening frame also becomes large, and it is difficult to attach the outer wall to the opening frame. Even if the outer wall is attached, the opening panel integrated with the outer wall also becomes large, so it cannot be loaded on a transport truck or the like and cannot be transported to a construction site. There is a problem that it is not possible to build a building with a wide opening such as a curtain wall.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to simplify the opening frame at the projected corner portion and to increase the width of the opening portion.
Instead of attaching the outer wall to the opening frame in advance at the factory so that the building can be built using the curtain wall, the components of the opening frame are carried to the building site together with the outer wall, and the opening frame is constructed at this building site. It is an object of the present invention to provide an open corner frame structure that can be assembled.
