DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for electrolytically treating an aluminum alloy, and more particularly to a method for electrolytically treating a heat-insulated material used for anodizing or electrolytic coloring of a heat-insulated material in which the members are connected to each other by a heat-insulating material. The present invention relates to a power supply jig for electrolytic treatment of a heat-insulated member.

2. Description of the Related Art A heat-insulated section formed by connecting an outdoor-side section and an indoor-side section by a connecting member made of a heat-insulating material prevents heat transfer between an outdoor section and an indoor-side section. By applying to building materials, it is possible to prevent dew condensation in winter and to increase the efficiency of cooling and heating, and the demand is increasing.

Conventionally, the exterior and interior profiles used for such heat-insulated profiles have been separately subjected to electrolytic coloring before connecting the two profiles, for example, a heat-insulating material such as phenolic resin. Insulated sections have been manufactured by connecting the outdoor-side section and the indoor-side section that have been subjected to the electrolytic coloring treatment using a connecting member. Also, at the time of connection, the connecting member is fixed by caulking the peripheral portion of the connection groove of the shape member with the end of the connection member fitted in the connection groove provided in both shape members, and the both shape member and the connection member are fixed. And was integrated.
