PROBLEM TO BE SOLVED: To improve a fireproof property, by preventing a thermal crack of a glass panel.SOLUTION: In a holding structure of a face bar, rail members 21, 22 and 23 are respectively provided in four-peripheral edge parts of the face bar 24 having the glass panels 24a and 24b of forming a rectangular shape so as to cover a part over an end surface of the face bar 24 from one surface of the face bar 24. Hollow parts 21c, 22c and 23c are provided along its longitudinal direction in the rail members 21, 22 and 23, and a metallic fireproof member 40 is arranged along the longitudinal direction of the rail members 21, 22 and 23 in the hollow parts 21c, 22c and 23c, and the fireproof member 40 is provided with a face bar cover part 43 for covering a space with a clearance up to the end surface of the face bar 24 from the one surface of the face bar 24 in the depth direction and inclined so as to gradually reduce an interval with the one surface of the face bar 24 toward the end surface of the face bar 24 from the one surface of the face bar 24. |
