Description

The present invention relates to an outer wall panel mounting aid and a method for mounting an outer wall panel.

For example, when constructing a steel-framed building in an urban area, there is often not enough space between the outer wall of the building to be constructed and the boundary of the adjacent land to assemble the scaffolding. Alternatively, even if the scaffolding can be assembled, there may be no space for the outer wall panel to enter between the scaffolding and the outer wall installation position, and further, there may be no space for installing the outer wall panel.

Normally, if there is sufficient space between the scaffold and the outer wall installation position, the outer wall panel lifted by a heavy machine such as a crane is dropped into this space, and the worker on the scaffold can use the outer wall panel. The posture is slanted so that the lower part faces the outer wall installation position side, and the mounting bolt attached to the lower end of the outer wall panel is first placed on the groove of the lower mounting bracket attached below the outer wall installation position on each floor. Install. Then, using the engaging portion between the mounting bolt and the groove as a fulcrum, the upper part of the outer wall panel is raised to the outer wall installation position side, and the upper part of the outer wall panel is rotated from the outdoor side to the indoor side in the out-of-plane direction. Align the bolt holes provided at the upper end of the panel with the bolt holes of the upper mounting bracket at the outer wall installation position. A through hole is formed by aligning both bolt holes, and the outer wall panel is attached by inserting a bolt through the through hole and tightening a nut.

That is, in this construction, the lower end of the outer wall panel is fixed, and with this as a fulcrum, the upper part of the outer wall panel draws an arc from the outdoor side to the indoor side and is installed while rotating by out-of-plane movement. A certain amount of space is required between the installation position and the scaffolding.

Therefore, as described above, a construction method has been proposed in which the outer wall panel can be suitably constructed even in a small site where there is no space for scaffolding. Specifically, guide rails are provided so as to extend in the longitudinal direction of the lower floor ceiling beams and the upper floor ceiling beams that constitute the building frame. On the other hand, a hanger hooked on the guide rail is attached to the upper end of the lower floor outer wall panel and the upper floor outer wall panel. Then, by hooking each hanger on the guide rail of each ceiling beam, each outer wall panel is in a state of being suspended from each ceiling beam. By sliding the hanger along the guide rail in this suspended state, each outer wall panel is moved to a predetermined mounting position. This is a construction method in which each outer wall panel is fixed from the indoor side with a bolt or the like at this mounting position (see, for example, Patent Document 1).
