2. Description of the Related Art In recent years, the construction of houses has become increasingly industrialized. For example, a panel construction method in which components such as walls, floors, and roofs are panelized in advance in a factory, and panels are assembled at a construction site to construct a building. Some have been adopted.
Panels used in the panel construction method are mainly wood panels, and vertical and horizontal frame members are assembled in a rectangular shape, and auxiliary supporting members are vertically and horizontally assembled inside the rectangular frame to form a frame. Alternatively, a face material is stuck on one side.

[0003] In such a panel construction method, industrialization has been further advanced.
As shown in Japanese Patent Publication No. 25, a siding (exterior finishing material) is previously attached to the surface of a wall panel in a factory or the like, and the outfitted wall panels to which the siding is attached are installed while being joined at a construction site. It has become to.

When the outfitting wall panel is joined on site,
This is performed by abutting and bonding the frames constituting the wall panel together, and by slanting a nail from one frame toward the other frame. This nailing is performed from the back side of the wall panel because siding is attached to the surface of the wall panel and nailing cannot be performed from the front side of the wall panel.

[0005]

As described above, when joining the outfitted wall panel to which the siding is attached, it was necessary to drive a nail from the back side of the wall panel. For example, there is a problem that a fireproof material such as a gypsum board cannot be outfitted in advance. This is because if the gypsum board is pre-installed on the back side of the panel, the gypsum board may be broken by nailing.
This is because repairs require considerable effort.

For this reason, at the construction site, a fireproof material such as a gypsum board has to be attached to the entire inner wall surface of the building, which requires much labor and time on the site.
