PURPOSE:To facilitate ceiling mounting work by obliquely crossing a plurality of hanger reinforcing materials with a hanger vertically installed to a corresponding cradling receiver and fixing the reinforcing materials to the hanger. CONSTITUTION:A ceiling panel 1 is formed from a gypsum board 18, cradlings 19a, 19b, 19c supporting and fixing the board 18, cradling receivers 6a, 6b and reinforcing materials 20a, 20b. Clamping fittings 21a, 21b are adjusted, the reinforcing materials 20a, 20b are fallen in the direction of the arrow D, and the panel 1 is transported to a construction field. On the construction field, the reinforcing materials 2Oa, 20b are opened in the direction of the arrow C, the gradients of the reinforcing materials 20a, 20b are conformed to a roof gradient, and two pairs of ceiling support materials 2L, 2S... are set up and fixed vertically onto the side faces of the cradling receivers 6a, 6b respectively. The intersections of the reinforcing materials 20a, 20b and the support materials 2L, 2S... are nailed respectively, thus constituting truss binding structure. The panel 1 is lifted to a roof unit, and the support materials 2L, 2S... are clamped to a rafter 12. |
