In the building exterior construction method according to this embodiment, a glass plate G is used as the exterior material.

  When constructing an exterior of a building, as shown in FIG. 1, a framework scaffold 110 is assembled on a construction floor 100 for constructing the exterior. 7 and 8, the above-mentioned gondola device (gondola stage 1) is installed on the upper floor 200 above the construction floor 100, while the upper floor is downstairs as shown in FIG. A pallet 310 with a carriage on which a glass plate G is mounted is carried into the exterior material supply floor 300. The glass plate G is mounted on the pallet 310 with a carriage so that the longitudinal direction is horizontal, and the longitudinal direction of the glass plate G has a length extending over a plurality of levels (for example, three levels) of the building.

  Thereafter, an external worker gets on the gondola 4, and the pallet 310 with the carriage is moved so that the transparent surface of the glass plate G faces the outside of the building on the exterior material supply floor 300. Then, the external worker and the internal worker inside the building cooperate to cause the exterior material gripping device 5 to grip the glass plate G. Thereafter, by rotating the glass plate G between the gondola 4 and the building, the longitudinal direction of the glass plate G becomes vertical.

  Thereafter, the wire 31 for suspending the exterior material is rewound from the hoist 3 for wrapping the exterior material, and the wire 22 for suspending the gondola from the gondola hoist 2 is rewound, so that the glass plate G passes between the gondola 4 and the building. 4 and hang up to the construction floor (construction position) 100.

  The glass plate G suspended to the construction floor 100 is attached and constructed by the cooperation of an external worker and an internal worker. Specifically, after a glass plate G is fitted into a frame (not shown) provided in the building, a pressing edge (not shown) is attached to the outside of the building, while rubber (not shown) is attached to the inside of the building. Z)), the glass plate G is attached to the exterior of the building.

  Then, when the glass plate G is attached and detached, the exterior material gripping device 5 is removed from the glass plate G, and then the exterior material construction hoist 3 winds up the exterior material suspension wire 31 and the gondola hoist 2 becomes the gondola. By winding up the suspension wire 22, the exterior material gripping device 5 and the gondola 4 are lifted to the exterior material supply floor 300.

  Thereafter, the construction procedure described above is repeated, and the exteriors of all construction floors 100 are constructed while leaving a part of the exterior material supply floor 300. After that, by using a lifting machine (not shown) such as a tower crane, the gondola device is rearranged to the upper floor of the upper floor 200, so that the exterior of the building is constructed following the construction of the frame. And when construction above the gondola stage 1 such as the top floor is required, a scaffold is built on the gondola stage 1 and a tower crane (not shown) or a mini crane (not shown) installed on the rooftop. The exterior of the building is constructed by using And finally, about the useless part which the steel material 11 of the gondola stage 1 penetrated, it constructs using a permanent gondola (not shown) etc. last.

  According to the building exterior construction method described above, the building exterior can be constructed even after the building frame is not completed. That is, the exterior of the building can be constructed following the construction of the building frame. Since the interior can be constructed for the level where the exterior construction of the building has been completed, the construction of the interior can be started before the building frame is completed.

  In addition, after the glass plate G is gripped by the exterior material gripping device suspended from the exterior material construction hoist 3, the glass plate G is moved (suspended) between the gondola 4 and the building together with the gondola 4. The glass plate G can be supplied to the construction floor 100 in a state where the influence of pressure is suppressed. Furthermore, if the gondola 4 is suspended to the lower floor where the exterior construction is completed, the exterior after the construction can be repaired.

  In the embodiment described above, the case where the glass plate G is used as the exterior material has been described. However, the exterior material is not limited to the glass plate G. Furthermore, the exterior material includes a frame for fixing the glass plate G or a frame for attaching the glass plate G.
