SUPPORTING STRUCTURE FOR RECTANGULAR DUCT FOR AIR CONDITIONING, AND DUCT BEARING TOOL FOR SAID DUCT

摘要

PURPOSE:To perform supporting construction without being influenced by the width of a rectangular duct by providing a pair of duct bearing tools which have a shape to fit the corner part of the rectangular duct, in such a manner that they are arranged to be in contact with the lower parts of the corners to be corresponding with each other such as pinching the duct. CONSTITUTION:A duct bearing tool 3 is constituted of a duct bearing part 4 and a connecting flange part 5. The duct bearing part 4 is formed into an approximate L shape by bending an approximately rectangular shaped metal plate or hard resin at around the center by an approximately right angle. Also, the connecting flange 5 is integrally formed by bending; both end edges of the duct bearing part 4 in the longitudinal direction to the outside of the L shape by an approximately right angle. In addition, at the approximate center of this connecting flange 5, a fastening hole 8 in which a suspension bolt 6 or connecting bolt 7 is penetrated is drilled.
