As described above, according to the curtain wall construction method of the present invention, the small units 21 and the like are assembled in a factory, and the small units 21 and the like are transported to the gantry 4 provided at an arbitrary place on the site. The large unit 40 ready to be attached to a building is assembled in a suspended state,
0 is hung up and attached to the building as it is.
Therefore, there is no need to perform the work of positioning and mounting panels one by one on a scaffold provided along a building as in the related art.

When the small units 21 and the like are mounted on the gantry 4, the small units 21 and the like arranged side by side located on both sides of one gantry 4 are turned upside down. Thus, the same finishing operation can be performed on the two small units 21 arranged in parallel, and the efficiency of the operation can be improved.

[0021]

According to the curtain wall construction method of the first aspect, the following effects can be obtained. (1) The large unit 40 which can be directly attached to the building is assembled on the gantry 4 provided at an arbitrary place on the site, and the large unit 40 is lifted and attached to the building as it is. The work of attaching panels to a building while positioning panels one by one on a scaffold provided along the way can be eliminated, and the curtain wall can be efficiently attached to the building.

(2) Since the small unit 21 and the like for manufacturing the large unit 40 can be manufactured at a factory, the large unit 40 can be efficiently manufactured on the gantry 4.

(3) The vertical base material 31 is installed in the small unit 21.
The large unit 40 can be assembled simply by attaching the small unit 21 to the permanent horizontal base material 34 of the gantry 4 and then connecting the small unit 24 via the permanent vertical base material 31. Therefore, the large unit 40 can be assembled efficiently.

(4) Temporary horizontal base material 3 for small unit 21 or the like
Since the second unit 2 is provided, deformation of the small unit 21 and the like at the time of transportation to the gantry 4 can be prevented.

(5) Temporary horizontal base material 3 for small unit 21 or the like
2, the temporary horizontal base material 32 is removed, and the temporary horizontal base material 32 is removed and attached to the permanent horizontal base material 34 of the gantry 4 at the place where the temporary horizontal base material 32 is attached. Therefore, the assembling work of the large unit 40 on the gantry 4 is easy.

(6) In the small unit 24, the temporary horizontal base material 3
2 and a temporary vertical base material 33 are provided.
33 can be removed and reused after assembling the large unit 40, so that production costs can be reduced.

According to the panel unit of the second aspect,
Since the curtain wall can be directly attached to the building, the curtain wall can be efficiently attached to the building. Further, the permanent horizontal base material can be supported by a hanging bracket at a portion other than the intersection with the permanent vertical base material.
