DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attaching a glass fiber heat insulating material to a sheet metal material and forming the architectural plate with a roll forming machine. A glass fiber heat insulating material sticking apparatus to a sheet metal material capable of forming various architectural plates from the sheet metal material without the glass fiber heat insulating material being peeled off from the sheet metal material, and Regarding the method.

[0002]

2. Description of the Related Art In recent years, as shown in FIG. 7, a building plate manufactured by attaching a glass fiber heat insulating material G to a thin metal material P _O and applying the same to a roll forming machine is often used.
The glass fiber heat insulating material G has a structure different from that of other types of heat insulating materials, for example, a foamed synthetic resin, urethane, or the like. Then, in a process of forming a material obtained by attaching a glass fiber heat insulating material G to a thin metal material P _{O serving} as a raw material of a building plate using an adhesive S to form a building plate with a roll forming machine, as shown in FIG. 8 (a), it frequently occurs that peeled off the glass fiber insulation G from sheet metal material P _O.

[0003] This is because the adhesive S has a relatively sticky property. Therefore, in a state where the glass fiber insulation G is simply stuck to the adhesive S applied to the thin metal material P _O ,
The adhesive S can only adhere to the surface of the glass fiber insulation G. That is, since the adhesive S has not penetrated into the interior of the glass fiber heat insulating material G, its adhesive force is extremely weak.

Further, the glass fiber insulation G is made of a thin metal material P.
_Because there are many relatively thick types for _O , etc.
When forming the building board from sheet metal material P _O, deviated mutually different extending ratio or contraction ratio of the sheet metal material P _O and fiberglass insulation G at the bending point, even these reasons Peeling is easy (see FIG. 8B). Once the glass fiber insulation G is peeled off from the sheet metal material P _O , it cannot be easily repaired at the construction site, and the building plate itself may have to be replaced. sell.

[0005]

[Problems that the Invention is to Solve like this, in order to bond the glass fiber insulation G via an adhesive agent S to the sheet metal material P _O, and sheet metal material P _O with a roll apparatus consisting of top and bottom pairs The glass fiber heat insulating material G is sandwiched and pressed to compress the glass fiber heat insulating material G in the thickness direction.
The adhesion state of the adhesive S to the surface is made as good as possible. However, this alone does not allow the adhesive S to easily penetrate into the glass fiber insulation G, and it takes time for the adhesive S to settle on both sides of the sheet metal material P _O and the glass fiber insulation G. However, it was difficult to obtain sufficient adhesion strength.

[0006]
