Description

The present invention relates to a continuous window structure.

2. Description of the Related Art Conventionally, in an opening of a building, there has been known a continuous window structure in which a joint like a mullion is arranged between two adjacent windows. In the continuous window structure, each frame of the window and the connecting portion are connected via a plate-shaped fixing member fixed to the connecting portion. In order to improve fire resistance, the fixing member and the frame are connected by an engaging portion that can be engaged with each other, thereby forming a structure that can withstand deformation when exposed to high heat (see, for example, Patent Document 1).

By securely connecting the frame and the connecting portion, penetration of the flame can be suppressed, but the connecting portion itself is exposed to high heat. A fireproof board is placed on the indoor side of the joint to improve the fire resistance of the joint itself.
