Air conditioning static pressure box arrangement structure

The invention relates to an air conditioning static pressure box arrangement structure. The invention provides an air conditioning static pressure box arrangement structure which is easy to install and capable of easily coping with a modification process with excellent safety. The air conditioning static pressure box arrangement structure (100) for air conditioning has a grating ceiling (10) formed by configuring a plurality of T-shaped keels (11) in a lattice shape, so as to build a ceiling in a building; an air conditioning static pressure box (20) carried on the T-shaped keels (11) of at least one partition forming the grating ceiling (10); and a plurality of fixing members (30) which are attached to the air conditioning static pressure box (20) so as to fix the air conditioning static pressure box (20) onto the T-shaped keels (11) by engaging the T-shaped keels (11). The fixing members (30) are capable of resiliently holding the T-shaped keels (11) of the grating ceiling (10) from the back side of the cei
