Roof access door and adiabatic box for its access door

摘要

(57) Abstract Objective Airtightness, it makes the roof access door which is superior heat-insulating, it is denseWith is. Constitution To fit adiabatic box 5 to box framework 1, fastening plate 7Conjunction doing, pressure fit it obtains sealant 2 and 6. As for adiabatic box 5The box 5-1 sealing the heat insulation material 5-2 inside, it constitutes. Advantages Adiabatic box 5 and sealant in pressure fit of 2 and 6The ri, airtightness, the heat insulation improves.
