FIXING STRUCTURE FOR OUTER FRAME OF INSPECTION DOOR
PROBLEM TO BE SOLVED: To provide a fixing structure for an outer frame of an inspection door which can improve installation workability of an inspection door.SOLUTION: A frame supporting member 3 disposed along at least a pair of opposing edges of an inspection door 2 formed in an inspection door setting surface 1 and an inspection door outer frame 7 to which a cylindrical part 4 is connected to the frame supporting member 3 by a stepped screw 6 which is larger than the nominal diameter of a shaft portion 5 are installed, and the screwing depth into the frame supporting member 3 of the stepped screw 6 is restricted by bringing the end surface of the cylindrical part 4 into contact with the frame supporting member 3, and the pulling force by the stepped screw 6 to the inspection door outer frame 7 is regulated.SELECTED DRAWING: Figure 1
【課題】点検口の設置作業性を向上させることのできる点検口外枠の固定構造を提供することを目的とする。【解決手段】点検口設置面１に開設した点検用開口２の対向する少なくとも一対の辺縁に沿って配設される枠支持材３と、円筒部４が軸部５の呼び径に比して大きな段付きネジ６により前記枠支持材３に連結される点検口外枠７とを有し、前記段付きネジ６は円筒部４の端面を枠支持材３に当接させて該枠支持材３へのねじ込み深さが規制され、点検口外枠７への段付きネジ６による引き込み力が規制される。【選択図】 図１
