CONFIRMING METHOD FOR FITTING ATTITUDE ANGLE OF SPHRINKLER HEAD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To simply measure the fitting attitude angle of a sprinkler head and fit it according to the design. ;SOLUTION: A sprinkler head 2 having an axial extension 7 and a horizontal mount section 10 is fitted to a side wall 1, a spirit level 12 is mounted on the axial extension 7, and the horizontality of the sprinkler head 2 in the longitudinal direction is detected. The spirit level 12 is mounted on the horizontal mount section 10, the horizontality of the sprinkler head 2 in the right and left directions is detected, and the crossing angle between the axial extension 7 and the side wall 1 is detected with a triangular rule.;COPYRIGHT: (C)1997,JPO
