PROBLEM TO BE SOLVED: To provide a hatch mounting structure for a thin-wall pressure-resistant container, capable of reducing, when mounting a hatch on the thin-wall pressure-reststant container by use of an insert plate, ovalization of an opening for attaching the insert plate. SOLUTION: The hatch mounting structure for forming attaching the hatch 6 to the insert plate 7, the insert plate 7 being attached to the opening 10 which is formed in a body portion 5 of the thin-wall pressure-resistant container 1 to which internal pressure is applied, the insert plate 7 is formed so that the plate thickness of the outer periphery to be attached to the opening 10 is equal to the plate thickness of the body portion 5, and the plate thickness of a central portion 7t of the insert plate 7 is larger than the plate thickness of the body portion through a tapered surface 12. The insert plate 7 is attached to the opening 10 so that the tapered surface 12 of the insert plate 7 is located inside the body portion 5. COPYRIGHT: (C)2011,JPO&INPIT |
