Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a plurality of curved-curtain-wall panels on a body-side fitting and a contour-shaped curve of a curved skeleton in a horizontal plane through the panel-side fittings. It is related to the structure attached along.

[Conventional technology]

To improve the appearance of the building, a semi-cylindrical building such as a balcony may be provided on the building body. This building is composed of a plurality of curtain wall panels arranged along the arc of a curved skeleton such as a foundation or a beam curved outward in the horizontal plane from the main body of the building. It is desired that the surface of the panel is a continuous arc surface when assembled by being attached to the body via the panel and a plurality of panels are arranged in the body.

The panel includes a semi-cylindrical panel having a curved front surface and a flat rear surface. In order to attach this panel to the curved skeleton, it is conceivable to attach a panel side fixture to the back surface of the panel, attach a skeleton side fixture to the curved skeleton, and engage these fixtures.

[Problems to be solved by the device]

However, it is difficult to accurately process a curved skeleton into an arc shape, and when a panel is attached via a fixture that is attached with this curved skeleton as a reference, the surfaces of multiple panels form a continuous arc surface. There is a problem that is not. In addition, in order to securely attach the panel to the curved skeleton that has multiple rows above and below, attach the skeleton side fixtures to the upper and lower curved skeletons respectively, and attach the upper and lower panel side fixtures to the top and bottom of the panel. It is possible to engage the tools together, but when attaching the panel to the uppermost curved skeleton, the attachment points of the skeleton side attachment and the panel side attachment are limited, and the attachment of the panel to the curved skeleton There is a problem that is insufficient.

Here, the object of the present invention is that even if the curved skeleton is not formed into an accurate arc, and the curved skeleton is the uppermost one, the curved surface of the uppermost curved skeleton is Another object of the present invention is to provide a curtain wall panel mounting structure capable of accurately mounting a curtain wall panel having a planar back surface.

[Means for Solving the Problems]

The mounting structure of the curved curtain wall panel of the present invention is
A plurality of curtain wall panels having a curved surface and a planar back surface along the outer shape curve of the uppermost curved skeleton that is curved in the horizontal plane, in other words, arranging a kamaboko-shaped panel, and arranging these panels. While being attached to a curved skeleton through the respective skeleton-side fittings and panel-side fittings having straight portions corresponding to the planar back surface, the skeleton-side fittings erected on the skeleton-side fittings, and the panel The panel-side mounting piece mounted on the panel is fixed, and an arc surface is formed on the surface of the panel in a state where the plurality of panels are arranged.

[Action]

In the present invention having such a configuration, the frame-side mounting tool in which the body-side mounting piece is erected is installed on the uppermost curved frame, and the panel-side mounting tool and the panel-side mounting tool are mounted on the planar rear surface of the plurality of kamaboko-shaped panels. The panels are attached to the uppermost curvilinear skeleton by attaching each piece and engaging the attachment pieces together and fixing the attachment pieces together. When the plurality of panels are attached to the curvilinear frame, an arc surface is formed from the surfaces of these panels.

Therefore, even if the curved skeleton is not an accurate arc,
The accuracy of the curved frame can be absorbed by the fixture. Further, since the panel is attached to the curved skeleton not only by the attachments but also by the attachment pieces, the attachment of this panel to the curved skeleton is ensured.
