[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an integrated panel of a refractory layer part and a heat insulating layer part for a freezing warehouse (including a container-type freezing warehouse), a wall structure for a freezing warehouse in which the panels are joined, and a freezing warehouse .
[0002]
[Prior art]
Conventional large-scale freezing warehouses are roughly classified into two types. The first type is a concrete frame type in which a heat insulating layer is provided on one or both of the inside and outside of the concrete frame, and the second type is a steel frame in which a heat insulating layer is provided on one or both sides of the steel frame. For example, JP-A-8-303026, JP-A-9-4251, and JP-A-9-32147 are disclosed.
[0003]
[Problems to be solved by the invention]
In the second steel frame type, the heat insulation properties at the attachment portions of the heat insulation panels and the joint portions between the heat insulation panels are important issues because many heat insulation panels are attached to the steel frame. In addition, it is effective to increase the size of one thermal insulation panel because reducing the number of joints between panels improves thermal insulation, but the strength of the thermal insulation panel itself and the joints is problematic as the size increases. Become.
