Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel mounting structure for forming an outer wall of a building or structure.

[0002]

2. Description of the Related Art Conventionally, this type of building panel (hereinafter, simply referred to as "panel") is attached to a wall substrate by, for example, FIG.
As shown in FIG. 2, the concave groove of the lower panel a ₁ is fixed to the wall base α made of a steel frame base by a fixing tool β such as a hex or a tex, and the upper panel a ₂ is dropped, and the concave groove is formed on the upper surface thereof.
That is, a mounting structure is being put on the market in which the head of the fixture β is covered and construction is performed sequentially from the lower stage to the upper stage.

[0003]

However, the above-mentioned mounting structure is only a mounting structure from the panel surface side, and as the buildings are becoming denser, the location intervals between the buildings become smaller as seen in today's large cities. There is a drawback that the above-described conventional mounting method cannot be used under the condition that the scaffolding for panel mounting cannot be installed from the front side because it is narrow. Further, since the panel is directly fixed to the wall foundation, the panel cannot follow the vibration of the wall foundation such as an earthquake, and there is a risk that the fixing portion is broken and peeled off.

[0004]

Therefore, in the present invention, a male,
To attach the panel formed by the female connection structure, the third angle is attached to the second angle attached to the side surface of the columnar wall base by welding or a fixture, and the third angle is attached using bolts and nuts. By attaching the other surface and the first angle with bolts and nuts, etc., and by attaching the other surface of the first angle and the fixing tool through the groove of the panel by welding, the panel is from the back side of the panel, that is, from the indoor side of the building. It proposes a structure that can be attached and can be attached without losing normal attachment strength and workability.
