2. Description of the Related Art A curtain wall using a frame unit unitized by assembling a vertical frame and a horizontal frame into a rectangular shape has a simple construction, resulting in high workability and assembly accuracy. In particular, when a dry-type sealing material is attached to the outer periphery of the frame, there is an advantage that the on-site sealing work is labor-saving and the like, and therefore, it tends to be frequently used as a method of forming a curtain wall.

In this unit type curtain wall,
Since the work of sealing the joints between the frame units is omitted, the water tightness between adjacent units is determined by the degree of adhesion between the two seals. The key point is ensuring the accuracy of the building. Conventionally, units are assembled while pressing the sealing material continuously circling the outer circumference of the frame in the in-plane direction as in, for example, Japanese Utility Model Laid-Open No. 1-102312, and the final positioning is adjusted with fasteners However, in the structure where the contact of the sealing material is the main clue for positioning, the adjacent unit is abutting between the convex surfaces, so it lacks the certainty of installation, and it takes time for positioning adjustment. Become.

The present invention has been made in view of the problem of installing a unit to which a sealing material is attached, and provides a curtain wall having a structure in which the sealing material is securely inserted and positioned while ensuring adhesion between the sealing materials. It is a new proposal.
