Description

  The present invention relates to a tape attaching device for joining seams between heat insulating materials of a single-sided metal plate heat insulating panel formed by attaching a metal plate to one side of a plurality of panel-like heat insulating materials arranged.

  For example, on the side walls of buildings such as refrigerated warehouses and frozen warehouses that store food in a low-temperature environment, urethane is foamed on the surface of the body constructed of cast concrete, and a metal plate is placed on the foamed urethane surface. Although there was a built-in structure such as pasting, there was a problem that the construction time became longer due to the reaction heat of urethane and the like. Therefore, a prefabricated side wall structure in which a pre-formed heat insulation panel is applied to the wall surface is widely used (see Patent Documents 1 and 2, etc.).
