Anti-drop fitting

Abstract

The anti - detachment fitting related to this article is used for a support fitting that fixes a pipe to a base through a heat - insulating support material, and is a fitting for preventing the support material from shifting and detaching from the support fitting. As shown in the reference diagram representing the specific usage state, the support fitting surrounds a support material a, which is integrated by passing a pipe (indicated by a two - dot chain line) through an internal space a1 and being joined vertically, with a U - shaped band b. Bolts b1, b1 at both ends of the U - shaped band b are inserted through the base c and fastened and fixed to the base c with nuts. Thereby, the pipe is supported and fixed to the base c with the support material a interposed therebetween. The anti - detachment fitting d has a locking wall portion d2 formed to rise wall - like from the peripheral edge of a flat plate portion d1. The flat plate portion d1 is interposed between the support material a and the base c, and the bolts b1, b1 are inserted through holes e, e in the flat plate portion d1 and fixed to the base c together with the U - shaped band b. The locking wall portions d2 located before and after in the longitudinal direction of the pipe in the fixed state have arc - shaped notches avoiding the heat - insulating material arranged on the outer periphery of the pipe, and the trapezoidal lower part a2 of the support material a is supported from the front and rear by the portions other than the notches. When the pipe has a longitudinal movement due to temperature fluctuations, the movement of the support material a is suppressed by the locking wall portion d2, preventing the support material a from following the pipe and detaching from the U - shaped band b.
