Roof structure and construction method

Abstract

To provide a roof structure with excellent workability and a construction method that can stably install folded roof panels regardless of thickness of a noncombustible insulation material and fix them firmly without local excessive load acting on the noncombustible insulation material.SOLUTION: A noncombustible insulation panel 3 is placed between beam materials 2, by inserting insulation spacers 11 between the bottom surface of the noncombustible insulation panels 3, entire surface of whose noncombustible insulation material 4 is covered with a thin metal sheet 5, and the top surface of the beam material 2. And steel materials 6 are installed by extending on the top surface of the noncombustible insulation panel 3, and connecting elements 9 are placed vertically through the noncombustible insulation panel 3 and insulation spacers 11. The top and bottom ends of the connecting elements 9 are fixed to the steel materials 6 and beam materials 2, respectively, and the beam materials 2, insulation spacers 11, noncombustible insulation panels 3, and steel materials 6 are connected integrally, and folded plate roof panels 8 are fixed and supported on a tight frame 7 that is fixed and erected above the steel materials 6.SELECTED DRAWING: Figure 1
