PURPOSE:To make it easy to change the position of installation for partition walls, illumination appliances, etc. by fitting a ceiling filter into each lattice square of a lattice-work for mounting ceiling filters which is assembled with airtightly sealed double-layer hollow frame construction members and communicating airtightly individ ual lattice squares. CONSTITUTION:A lattice-work 12 for mounting ceiling filters has in each lattice hollow frame construction members 121 which have a double-layer construction with both layers in vertical direction and airtightly sealed from each other. The hollow frame construction member 121 is made of aluminum, steel, etc. and has in its cross section a squarish 8-shape and the upper and lower layers of it form the hollow main section 1211, and on the center of the upper face of the main section a hollow projecting channel 1212 is provided. The filter mounting lattice-work 12 is supported by hanging bolts 26... that hang from ceiling slabs or ceiling beams. A silicone seal is placed between the outer peripheral face of the lattice-work 12 and the surrounding walls. A ceiling filter 13... is fitted into each lattice of the lattice-work 12, the periphery of each ceiling filter mounting on the upper face of the main section 1211 of the hollow frame construction member 121 which constitutes the lattice-work and the ceiling filter is airtightly supported by the upper layer section a of said main section. |
