Description

The present invention relates to an external wall panel installation aid and an external wall panel installation method.

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 border of the neighboring property to assemble scaffolding. Alternatively, even if scaffolding could be erected, there may not be a space between the scaffolding and the exterior wall installation position for the exterior wall panel to fit in, or furthermore, there may not be space for installing the exterior wall panel.

Normally, if there is sufficient space between the scaffold and the location where the exterior wall is installed, the exterior wall panel lifted by a crane or other heavy equipment is dropped into this space, and the worker on the scaffold can move the exterior wall panel into place. Position it diagonally with the lower side facing the exterior wall installation location, and first insert the mounting bolts attached to the bottom end of the exterior wall panel into the grooves of the lower mounting brackets installed below the exterior wall installation location on each floor. Install. Then, using the engagement portion between the mounting bolt and the groove as a fulcrum, raise the upper part of the outer wall panel toward the outer wall installation position side, and rotate the upper part of the outer wall panel in an out-of-plane direction from the outdoor side to the indoor side. Align the bolt holes at the top of the panel with the bolt holes in the upper mounting bracket at the outside wall installation location. A through hole is formed by aligning both bolt holes, and the outer wall panel is attached by inserting a bolt into this through hole and tightening a nut.

In other words, in this construction, the lower end of the exterior wall panel is fixed, and the upper part of the exterior wall panel is installed by rotating out of plane in an arc from the outdoor side to the indoor side, using this as a fulcrum. A certain amount of space is required between the installation location and the scaffolding.

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

Japanese Patent Application Publication No. 2008-127927

According to the construction method described in Patent Document 1, exterior wall panels can be constructed even on a narrow site where there is no space for installing scaffolding. However, guide rails are provided to extend in the longitudinal direction of the lower floor ceiling beam and the upper floor ceiling beam, and hangers that are hooked on the guide rails are attached to the upper ends of the lower floor exterior wall panel and the upper floor exterior wall panel, respectively. Since each external wall panel is hung by hooking it on the guide rail of each ceiling beam, and the hanger is slid along the guide rail, the temporary member becomes large-scale, and there is an issue regarding the manufacturing cost of the temporary member. Furthermore, there is the problem that installation of large-scale temporary members and removal of temporary members after installation of exterior wall panels requires a great deal of effort and time.

The present invention has been made in view of the above problems, and makes it possible to efficiently install exterior wall panels without requiring the installation or removal of large-scale temporary members, even in narrow sites where there is no space for installing scaffolding.
