Description

  The present invention relates to a glass panel fixing structure in which a glass panel covering an inner side of a shaft or a frame is fixed.

Conventionally, in the above glass panel fixing structure, when an external force in the direction along the glass surface acts on the glass panel, stress is likely to concentrate on a part of the glass panel, and it is damaged due to cracks occurring at the stress concentration location. In consideration of easy points, the glass panel is not rigidly connected to the inner side of the frame or the frame as a building structural member. Even if a horizontal external force acts on the frame or the frame, an external force is applied to the glass panel. Is fixed to the inside of the shaft or the frame through an elastic cushioning material or the like so that it does not act as much as possible (it is a conventional technique and information on prior art documents cannot be disclosed).
In addition, in the frame or frame structure, deformation of the frame or frame due to horizontal force due to wind or earthquake, for example, between the shafts at the two corners facing each other along one diagonal of the frame or frame. Providing metal braces so that the crossing angle can be effectively prevented and the crossing angle between the shafts at the two corners facing each other along the other diagonal line can be effectively prevented. Is generally done.

For this reason, in order to prevent deformation of the frame or the frame, if a brace that crosses the glass panel along the glass surface is provided, the view through the glass panel is blocked by the brace, and the interior and exterior of the building and There is a defect that impairs the transparency through the glass panel, and the larger the brace having a higher tensile strength, the larger the defect.
The present invention has been made in view of the above circumstances, and it is possible to prevent deformation of the frame or the frame by utilizing the glass panel without particularly impairing the interior appearance of the building and the transparency through the glass panel. The purpose is to do.

  A first characteristic configuration of the present invention is a glass panel fixing structure in which a glass panel covering an inner side of a shaft or a frame is fixed, and the inner peripheral side of the shaft or the frame is a series of frames. A series of annular ribs are integrally provided on the inner periphery side of the frame body along the inner periphery, and the peripheral portions of a pair of polygonal plate glasses having substantially the same shape in plan view are provided on each plate glass. A multi-layer glass panel is formed in which each side is opposed to each other so as to be substantially parallel to each other and is hermetically fixed with the annular rib interposed therebetween to form an airtight space between the glass surfaces. A spacer that is softer than the plate glass and capable of transmitting an external force across the frame body and the plate glass is mounted between the end surface along each side of the plate glass and the frame body. It is in.

[Action and effect]
The inner circumference side of the shaft assembly or the frame structure is constituted by a series of frame bodies, and a series of annular ribs are integrally provided along the inner circumference side of the frame body. Can be reinforced.
Further, by using the annular rib as a spacer for forming an airtight space, the peripheral portions of a pair of polygonal plate glasses having substantially the same shape in plan view are arranged so that the side edges of each plate glass are substantially parallel to each other. It is opposed and airtightly fixed with an annular rib in between, and a multi-layer glass panel is formed in which an airtight space is formed between the glass surfaces. A multi-layer glass panel having excellent properties can be integrally fixed to the inner peripheral side of the shaft or frame.
And since the spacer which is softer than the plate glass and can transmit the external force over the frame and the plate glass is mounted between the end surface along each side of the plate glass and the frame, the shaft assembly or Along with the deformation of the frame, a compressive force can be positively applied to the plate glass from the frame body via the spacer while preventing stress concentration, and therefore the shaft frame or the frame frame based on the compression resistance strength of the plate glass. Can be utilized as a strength member that reinforces the frame structure or the frame structure.
Therefore, it is possible to prevent deformation of the frame or the frame by utilizing the multi-layer glass panel without particularly impairing the inside appearance of the building and the transparency through the multi-layer glass panel.

  A second characteristic configuration of the present invention is that the spacer is mounted at a distance of 25.4 mm (1 inch) or more from the corner portion.

[Action and effect]
Since the spacer is mounted at a distance of 25.4 mm (1 inch) or more from the corner portion of the plate glass so that the compressive force does not concentrate on a narrow range around the corner portion of the plate glass, as described later, It is possible to secure a large breaking load of the plate glass accompanying the deformation of the shaft group or the frame group.

  According to a third characteristic configuration of the present invention, the shape of the inner peripheral surface of the annular rib is substantially tangential to the front and rear inner peripheral surfaces sandwiching the peripheral surface portion in the peripheral surface portion along the corner portion of the plate glass. It is in the point formed in the curved surface which continues in series.

[Action and effect]
The shape of the inner peripheral surface of the annular rib is formed into a curved surface that is continuous in a series from the substantially tangential direction with respect to the inner peripheral surface before and after sandwiching the peripheral surface portion in the peripheral surface portion along the corner portion of the plate glass. Therefore, the stress acting on the annular rib is less likely to concentrate on the peripheral surface portion along the corner portion of the plate glass.

  A fourth characteristic configuration of the present invention is that a desiccant container is provided in the annular rib in communication with the airtight space.

[Action and effect]
The desiccant storage part communicates with the airtight space and is provided on the annular rib. Therefore, the airtight space is maintained in a dry state in which condensation is unlikely to occur without providing a separate member for forming the storage part. it can.

  A fifth characteristic configuration of the present invention is that the frame body and the annular rib are made of a metal material, and the spacer is made of a material softer than the plate glass and the frame body.

[Action and effect]
Since the frame body and the annular rib are made of a metal material, and the spacer is made of a softer material than the plate glass and the frame body, the shaft or the frame can be more effectively reinforced.
