2. Description of the Related Art Among glass screen methods for forming a large opening using a large plate glass as an outer wall of a building, a glass stabilizer method and a hanging stabilizer method are well known as methods using rib glass (glass cubic). I have.

The glass stabilizer method is also called a self-supporting method with a glass cubic, and uses rib glass (also referred to as a cubic glass or a glass stabilizer) to support the deflection caused by the weight of the face glass and the wind load applied to the face glass. The hanging stabilizer method is a method of suspending the upper side of the glass plate and using a rib glass to prevent bending of the glass plate due to its own weight, and is used when the height of the glass plate at the opening is high. It is.

Usually, the thickness and size of the rib glass are determined depending on the thickness and size of the face glass, and a glass sheet which has not been tempered is usually used. When strengthening long glass sheets, not only is a very large tempering furnace necessary,
In strengthening a glass sheet having a narrow width such as rib glass, warpage of the glass sheet at the time of strengthening is a concern, and manufacturing is not easy. Therefore, when a tempered glass plate is used as the rib glass plate, its size is limited, and a method of connecting short glass plates has been performed.

For example, Japanese Utility Model Laid-Open No. 63-132008 discloses a construction in which a rib glass is erected between a ceiling and a floor of a frame, and a face glass is attached to one side of the rib glass in a direction orthogonal to the rib glass. Wherein the rib glass is
In a construction structure of a glass wall in which a plurality of short tempered glasses are formed by connecting a lower end and an upper end of each short glass to a long one, a metal frame is attached to an upper end and a lower end of the short glass. , Bolts are screwed through the frame and the glass and screwed, and a synthetic resin is injected and hardened into the gap between the glass and the frame of the crown portion, and the frame at the lower end of the short glass on the upper side and the short glass on the lower side. There is disclosed a construction structure of a glass wall in which a short glass is connected by fastening a frame at an upper end with a bolt.
