[0022]
In the plate glass support structure shown in FIGS. 1 to 3, a gap is formed between the glass wall surface 2 and the end portion on the outdoor B side of the upper portion of the rib plate glass 3 having a laminated glass structure composed of two plate glasses 3 a and 3 b. The notch part 13 for forming is provided.
The notch 13 is formed with a recess 14 that is recessed in a concave curve toward the room A side, and is recessed at the end closer to the room A side at the top of the rib plate glass 3 toward the outdoor B side. A concave portion 15 that is recessed in a curved shape is formed.
[0023]
In each of the recesses 14 and 15, metal convex adjustment members 18 and 19 having convex portions protruding in a convex curve shape according to the recesses 14 and 15 through buffer members 16 and 17 such as aluminum molded products, respectively. Are mated.
[0024]
On the upper part of the rib plate glass 3, a gripping member 20 having a U-shaped planar shape with an open end on the outdoor B side is externally fitted to the rib plate glass 3 from the room A side toward the B side. The rib plate glass 3 is held in the plate thickness direction by the 20 parallel portions 20a and 20b.
[0025]
A lid member 21 is fixed to the end of each parallel portion 20a, 20b closer to the outdoor B side with a bolt 22 so as to close the opening of the gripping member 20. Moreover, between each parallel part 20a, 20b and the rib plate glass 3, the buffer member 23, such as a rubber molded product, is interposed. As described above, the lid member 21 is not in contact with the glass wall surface 2 because the notch 13 is provided in the upper portion of the rib plate glass 3.
[0026]
The convex adjusting member 18 near the outdoor B side is fixed to the lid member 21 by a bolt 24, and the convex adjusting member 19 close to the indoor A side is fixed to the gripping member 20 by a bolt 25.
That is, the convex adjustment members 18 and 19 are fixed to the lid member 21 and the holding member 20 in a state where the convex adjustment members 18 and 19 are fitted to the concave portions 14 and 15 of the rib plate glass 3 via the buffer members 16 and 17. The upper part of the rib plate glass 3 is supported by the holding member 20 by means of 18 and 19.
