PURPOSE:To eliminate complicated assembling and fitting works at a construction site and simplify the works and increase the efficiency thereof. CONSTITUTION:A ceiling substrate panel 10 is composed of a substrate panel body 20 made of substrate materials 22 longitudinally and latitudinally assembled to form a lattice and reinforcing materials 30 attached to the external face of the longitudinal sides 24 of the substrate body 20 and made of plywood protruded upward from the upper face of the longitudinal sides 24. The ceiling substrate panel 10 is fabricated in advance in accordance with the dimensions of rooms to attach it and the length of ceiling substrate panel 10 corresponds to the length of the room and the width thereof also corresponds to the divided width of the room. In the ceiling substrate structure, the external face of the reinforcing members 30 at the wall side of ceiling substrate panel 10 and the wall 80, the shorter side and the wall 80, mutual external faces of reinforcing members 30 of the ceiling substrate panel 10, are fixed to each other with nails by a necessary number in accordance with the space of room. |
