DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of vertical joints formed when connecting building panels (hereinafter simply referred to as "panels") useful for constructing an outer wall and an inner wall of a building or a building. More specifically, the present invention relates to a vertical joint structure which is improved in waterproofness as a complete surface water-stopping structure, and is excellent in fire resistance and heat insulation.

[0002]

2. Description of the Related Art Conventionally, as a structure for accommodating a vertical joint of this kind, as shown in FIG. 16, a fixing member β is used on a wall base α made of a steel frame base or the like to form a thin iron plate in a hat-shaped section. long by decorative cover a and Joyner b of scale is intended to cover the panel c edge, as the method, blind rivet or the like facing the projecting portions b ₁ between the projecting portions a ₁ and Joyner b of the decorative cover a With the fixing β of
