PROBLEM TO BE SOLVED: To offer a mounting structure which can make mounting on sash members arranged in a lattice form on the fit-in system while the air-tightness is well secured. SOLUTION: In a lattice form, sash members 3 are installed where supporting pieces 2 having different protruding dimension are furnished protrusively from the bottom of a vertical piece 1 on its both sides. In a rectangular installation space surrounded by the sash members 3, a ceiling panel 7 is furnished in which mortises 5 are formed in three continued ones of the four edge members while a tennon 6 is formed on the remaining edge member, the supporting pieces 2a of two edge members adjacent of adjoining sash members 3 should have a small protruding dimension, while the supporting pieces 2b of the other two edge members adjacent of the adjoining sash members 3 should have a large protruding dimension. The three mortises 5 of the ceiling panel 7 are engaged by two supporting pieces adjacent 2a and one supporting piece 2b, while the tennon 6 is installed in contact with the undersurface of the remaining supporting piece 2b. The supporting piece 2b is equipped with an energizing means 8 which presses the ceiling panel 7 toward the adjacent supporting piece 2a. |
