Description of the Related Art In a curtain wall in which an outer wall panel is attached to the outside of a structural skeleton including columns and beams to form an outer wall, a dry joint material such as a gasket is previously attached to the end surface of the outer wall panel, and the panel is attached At the same time, it is considered that each joint material is brought into close contact with each other so that the joint portion is airtight or watertight.

As described above, by attaching the dry joint material in advance, the work of filling the joint material after the panel is attached becomes unnecessary, and there is an advantage that the man-hours can be greatly reduced and the construction period can be shortened.

[0004]

As described above, by installing the dry joint material in the curtain wall structure in advance, there is an advantage that the construction period can be shortened. However, when the outer wall panel is attached, the outer wall that is attached first is installed. If another panel is attached next to the panel by inserting it from the outside, the joint material of the panel to be attached interferes with the joint material of the previously installed panel, and they stick together in a distorted state. However, there is an inconvenience that correction work is required.

In such a case, the panel is not positioned and mounted at an accurate position from the beginning, but is installed loosely while the jointing materials do not interfere with each other or the distortion is corrected, and finally the correct position is set. It is convenient to be able to position and fix to.

In view of the above points, the present invention has an object to provide a curtain wall fixing structure in which the panels constituting the corners of the outer wall can be adjusted and positioned after mounting. It is a thing.

[0007]

In order to solve the above-mentioned problems, according to the present invention, there is provided a fixing device for an outer wall corner panel having an L-shaped cross section which constitutes a corner portion of the outer wall, and is attached to a structural frame of the corner portion. The height of the corner panel can be adjusted by the vertical support bolts, which are composed of a support metal fitting that is provided and a bracket that is provided on the rear surface of the corner panel, and that is arranged across the horizontal support portion of the support metal fitting and the horizontal portion of the bracket. The tips of a pair of horizontal direction entry / exit adjustment bolts that are supported and are also screwed into the support fittings and project outwards abut the back surfaces of the corresponding corner panel in the left-right direction, and It is characterized by supporting inward and outward directions.

In the above, as the structural body, a corner column such as a square steel pipe is usually used.

It is also conceivable that the support bolt is inserted into a bolt hole formed in the horizontal portion of the bracket and is supported from below by a support member provided on the support bolt.

In this case, the invention according to claim 4 is characterized in that the support member is a flange integral with the support bolt, and the support bolt is screwed into the screw hole of the horizontal support portion.

Further, in the invention of claim 5 of this application, the support fitting is provided with an anti-sway projection projecting outward above the support bolt, and the projection is provided on the corner panel. The present invention is characterized in that the corner panel is inserted into a slit in the vertical direction of a lower bracket provided at the lower end or in the vicinity of the lower end to prevent the corner panel from swaying in the horizontal direction.

[0012]

[Function] Since the height of the corner panel can be adjusted with the support bolts and it can be rotated horizontally around this support bolt, it should be installed loosely while avoiding interference between jointing materials during installation. It can be positioned and fixed formally. Alternatively, the panel can be moved after installation to correct the joint material distortion.
