VACUUM STRUCTURAL BODY, VACUUM THERMAL INSULATION PANEL, SEALING METHOD FOR VACUUM STRUCTURAL BODY, AND MANUFACTURING METHOD FOR VACUUM STRUCTURAL BODY

摘要

PROBLEM TO BE SOLVED: To provide a valve-less vacuum structural body by improving a closing material for closing the exhaust port of the vacuum structural body.

SOLUTION: A nozzle 13 is fitted to the panel upper surface 10 of a vacuum insulation panel to form an exhaust port 20, and the closing material is fitted thereto to close the exhaust port 20. The closing material 30 is formed of a screw material of roughly T-shape in longitudinal section, comprises an inlet hole 32 formed in the bottom face 31 of a screw part in contact with a vacuum space 11 inside the vacuum heat insulation panel and an exhaust hole 35 formed in a screw part side face 34 inside in contact with the inner wall 21 of the exhaust port 20, and comprises a through hole 39 connecting the inlet hole 32 to the exhaust hole 35.
