Become.

In the present invention, as the metal panel, various metal plates such as a copper plate, a steel plate, a stainless plate, and an aluminum plate formed in a shallow box shape can be used, and in particular, an enamel panel provided with an enamel layer at least on its surface side. Is preferable in terms of durability.

In this invention, as the backing material, it is preferable to use a honeycomb material such as an aluminum honeycomb sheet or a paper honeycomb sheet subjected to a flame-retardant treatment from the viewpoint of weight reduction, but it is also possible to use a fire-resistant board such as a calcium silicate plate. .

As the impermeable layer applied to the back side of the backing material, it is possible to use a metal plate such as a zinc iron plate, a color iron plate, or an aluminum sheet, or a plate made of various materials such as a plastic sheet that prevents water from permeating. However, when the backing material is a fireproof board, a coating film formed by applying a waterproof coating material may be used as the water impermeable material layer in addition to these plate materials.

The packing used in this invention may be made of an elastic material such as rubber or plastic.

[Action]

In the construction panel of the present invention, when the mounting bracket is fastened and fixed to the base material fixed to the building frame with the tapping screw, the packing part adhered to the inner curved piece is between the base material and the inner curved piece. A seal layer is formed by being sandwiched between and to prevent rainwater from entering the inside of the panel (building body side) when the joint is broken. In addition, the packing part that is press-fitted between the inner peripheral edge of the inner curved piece and the outer peripheral edge of the water impermeable material layer prevents water from entering the inside of the panel from between the inner peripheral edge and the outer peripheral edge, and The material layer prevents water from entering the backing material from the back side, and prevents water from entering the inside of the backing material or the metal panel, resulting in corrosion of the backing material or metal panel, and backing material. When the is a fireproof board, it is possible to prevent deformation due to water absorption.
