If it is the outer wall of the building described above, it is very difficult to remove the panel, and it is troublesome to replace the panel when the panel is damaged, and maintenance is difficult.
In order to solve this problem, it is conceivable that the panel can be mounted upright, bolted to a cross member, and the panel can be removed by loosening the bolt. In order to remove, it is necessary to tighten and loosen a plurality of bolts, and it is troublesome to install and remove the panel, so maintenance is also troublesome.
In addition, the panel may fall off due to the bolt loosening and falling off due to vibration or the like.

  An object of the present invention is to provide an outer wall of a building and an outer wall unit of the building in which the panel can be easily mounted and removed, the panel can be easily maintained, and the panel does not fall off.

The outer wall of the building of the present invention has a plurality of panel units that are sequentially attached to the building frame in the vertical direction, and each panel unit has a plurality of panels that are sequentially arranged in the vertical direction.
Each panel is attached to the building frame side with an upper fastener and a lower fastener,
The upper fastener attaches the upper part of the panel to the building frame by connecting the upper receiving part provided on the building frame side and the upper mounting part provided on the panel with a mounting bolt,
The lower fastener is attached so that the lower receiving part provided on the building frame side and the lower mounting part provided on the panel do not move in the indoor exterior direction, and the lower panel part is attached to the building frame.
The upper fastener mounting bolt for attaching the uppermost panel of the panel unit can be extracted without interfering with the lowermost panel of the other panel unit located on the uppermost panel.
The upper fastener mounting bolt that attaches a panel other than the uppermost panel interferes with the panel located above the panel and cannot be pulled out.
A support is attached to the uppermost panel, a support is attached to the building frame side, and the support and the support engage with each other so that the downward movement of the uppermost panel is restricted and supported. It is an outer wall of a building characterized by the use of tools.

In the present invention, the mounting bolt can be loosened by inserting a tool from the outdoor side into the uppermost joint portion between the uppermost panel and the lowermost panel of the two panel units adjacent vertically. It can be configured as follows.
In this way, since the tool can be inserted from the uppermost joint and the mounting bolt can be loosened and extracted, maintenance can be performed by removing or attaching the panel from the outdoor side.

In the present invention, the upper mounting portion of the upper fastener is in contact with the upper surface of the upper receiving portion, and the mounting bolt is screwed and connected to the screw hole of the upper receiving portion from the through hole of the upper mounting portion.
The lower attachment portion of the lower fastener has a concave portion, and the concave portion can be connected to the lower receiving portion without a gap so as not to move in the indoor outside direction.
In this way, while supporting the panel, the concave portion of the lower mounting portion is fitted to the lower receiving portion, and the upper mounting portion is temporarily attached in contact with the upper surface of the upper receiving portion, and the mounting screw is passed through in this state. Since the panel can be mounted by screwing into the screw hole from the hole, the panel is easily mounted.

In the outer wall unit of the present invention, a plurality of panels are sequentially attached to the attachment frame body in the vertical direction with the upper fastener and the lower fastener,

Panels can be attached and detached by connecting and disconnecting.
Further, if the uppermost panel is removed by loosening and removing the mounting bolts of the uppermost upper fastener, the panels can be subsequently removed.
Therefore, the panel can be easily attached and detached, and the panel can be easily maintained.

Further, the uppermost panel of the panel unit is supported on the building housing side by a drop-off prevention tool, and even if the mounting bolt loosens and comes out, the upper part of the panel is supported by the drop-off prevention tool and does not fall off.
Since the mounting bolt of the upper fastener for attaching the panel other than the uppermost part of the panel unit does not come out even if it is loosened, the panel does not fall off.
Therefore, the panel does not fall off.
In addition, since the drop-off prevention device is provided only on the uppermost panel and is not provided on the other panels, the number of drop-off prevention devices is small and the cost can be reduced.

  In the case of the outer wall unit of the present invention, the mounting frame is sequentially attached to the building frame in the vertical direction, and the upper fastener mounting bolt for attaching the uppermost panel of the outer wall unit is located on the outer wall unit. By enabling extraction without interfering with the lowermost panel of other outer wall units, the panel can be easily installed and removed, and panel maintenance is easy. can do.
