Glass panel support structure
A glass panel support structure supports multi-glazed glass of which a circumferential edge part is bonded to a frame that frames all sides. The glass panel support structure includes a first structural sealant that bonds an indoor-side glass plate of the multi-glazed glass and the frame over an entire circumference, and a spacer provided between glass plates of the multi-glazed glass over the entire circumference. Along a first direction perpendicular to an indoor and outdoor direction of the multi-glazed glass, a position of an inner circumferential surface of the spacer is identical with a position of an inner circumferential surface of the first structural sealant or is located on outer circumferential side with respect to position of the inner circumferential surface of the first structural sealant.
1. A glass panel support structure that supports multi-glazed glass of which a circumferential edge part is bonded to a frame that frames all sides, the glass panel support structure comprising:
a first structural sealant that bonds an indoor-side glass plate of the multi-glazed glass and the frame over an entire circumference, forming a space between the frame and an outer edge of the first structural sealant, wherein the multi-glazed glass is supported on a first side by the first structural sealant and a second side of the multi-glazed glass, opposite the first side, is not in contact with a sealant; and
a spacer provided between glass plates of the multi-glazed glass over the entire circumference, wherein
along a first direction perpendicular to an indoor and outdoor direction of the multi-glazed glass, a position of an inner circumferential surface of the spacer is located on outer circumferential side with respect to position of the inner circumferential surface of the first structural sealant, and the glass plates of the multi-glazed glass are attached to a glass support surface of a glass attachment part of the frame such that one or more setting blocks provided not over an entire circumference of the glass support surface are positioned between an outer circumferential edge of the multi-glazed glass and the glass support surface of the glass attachment part,
the space is formed by the glass support surface, an indoor side of the setting block, and the outer edge of the first structural sealant,
on the inner circumferential surface of the first structural sealant, a backup material is provided, and along the first direction, the inner circumferential surface of the spacer is located on outer circumferential side with respect to a boundary surface between the first structural sealant and the backup material, and
the first structural sealant extends from an outer circumferential edge of the multi-glazed glass to an outer circumferential edge of the backup material along the first direction.
2. The glass panel support structure of claim 1 , wherein the first structural sealant and the backup material are provided over entire circumference of circumferential edge part of the multi-glazed glass.
3. The glass panel support structure of claim 1 , wherein the first structural sealant is spaced apart from a glass support surface of the frame in the first direction, and the glass support surface supports circumferential edge part of the multi-glazed glass.
4. The glass panel support structure of claim 1 , wherein a side surface of the multi-glazed glass on the indoor side is supported by the frame via the first structural sealant, and a space is formed between outer circumferential edge of the multi-glazed glass and the frame.
5. The glass panel support structure of claim 1 , wherein
the spacer comprises a spacer member and a second structural sealant having a water stop function, and
the first structural sealant and the second structural sealant are arranged to overlap each other in the first direction.
