Abstract:
PROBLEM TO BE SOLVED: To sufficiently fill even a region to which a glass retainer is attached with a foamed heating foaming material while arranging the glass retainer for preventing a fall of glass at a fire in a space of a glass opening.SOLUTION: A fireproof sash comprises a frame body which is formed by framing a frame material, a panel body attached to an internal periphery of the frame body, and a panel retainer for preventing the come-off of the panel body from the frame body. The panel retainer is attached to a bottom wall portion of the panel opening, and a heating foaming material is arranged over a substantially-entire length of the frame material in a longitudinal direction at one side in a depth direction of the panel retainer at a frame main body portion for forming the panel opening. The panel retainer is composed of a base metal fitting fixed to the bottom wall portion of the panel opening, and a receiving metal fitting having a glass receiving face which abuts on or approximates the other side face of the panel body, and a clearance for allowing the intrusion of the foamed heating foaming material into the other side of the base metal fitting is formed at the base metal fitting.SELECTED DRAWING: Figure 5
