METHOD OF ASSEMBLING STRINGER ADAPTED TO SIDE WALL AND ROOF OF THERMAL INSULATION CONTAINER

摘要

Gaps between outside panels and inside panels of a container are filled with polyurethan material for insulation. Unit volumes formed by stringers are fixed in the gaps, so that density of the material is maintained constant. A jointed stringer comprises a 'I' type supporting part (7) and an upper rail (6) having a groove (6b) to insert the supporting part to the upper part not to leak the insulation material.
