Abstract

PURPOSE:To install a construction panel from the reverse surface side (inside of a construction) under the condition where the construction panel can not be installed from the obverse surface side. CONSTITUTION:The male and female connection parts of construction panels A are fitted through an installation tool 27 by fitting the engagement part 27 of an installation tool B with the male real part of the construction panel A for longitudinal laying which is formed by the male and female connection structure, by using the installation tool B consisting of a rectangular planary fixed surface 23, installation surface which is formed by bending one side edge of the fixed surface 23 nearly vertically and upward, and the engagement part 27 which is formed by bending at least one side edge of the installation surface to the nearly same shape to the male real part of the construction panel A. The fixed surface 23 of the installation tool B is fixed on the upper surface of a pillar-shaped wall substrate D which is installed horizontally on the body, through a fixing tool C such as textile and machine screws. Accordingly, the construction panel A can be installed from on the reverse surface side, i.e., from the room inside of a structure. Further, installation can be carried out without deteriorating the ordinary installation strength and the execution performance.

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]

Conventionally, building panels for longitudinal tension of this type (hereinafter, simply referred to as panel) is attached to the wall base α of, for example, hex the groove of the panel a ₁ on the left side as shown in FIG. 10 , Fix it to the wall foundation α made of steel frame foundation with the fixture β such as tex, insert the right side panel a ₂ and apply it to the left and right while covering the groove of the fixture β, that is, the head of the fixture β sequentially. Go-to mounting structures are on the market.

[0003]

However, the above-mentioned mounting structure is a mounting structure from the panel surface side to the last, and due to the density of buildings as seen in today's large cities, the space between buildings is There is a drawback in that the conventional mounting structure described above cannot be used under such a narrow condition that a scaffold for mounting a panel cannot be installed from the front side.

[0004]

Therefore, in the present invention, a male,
By fitting the engaging portion of the fixture to the male part of the panel formed by the female connection structure, the male of the panel is attached via the fixture,
By fitting the female connecting part and fixing the fixing surface of the fixture to the upper surface of the columnar wall base that is horizontally attached to the body via a fixture such as a tex or screw screw, the panel is attached to the panel. This is a structure that can be mounted from the back side, that is, from the indoor side of a building, and can be mounted without losing normal mounting strength and workability.
