CONSTRUCTION METHOD OF HORIZONTALLY LAID ROOF, AND HORIZONTALLY LAID ROOF

摘要

PROBLEM TO BE SOLVED: To provide a construction method of a horizontally laid roof which can be safely and surely laid from an upstream side to a downstream side along an inclined slope of a roof substrate, and can be applied to both of new construction and repair, and to provide a horizontally laid roof.;SOLUTION: A construction method of a horizontally laid roof includes: a first step of fitting a projection 23 provided on a water lower end of a heat insulation material 2 into a rear face side of a water downstream molding section 12 of a horizontally laid external facing material 1, and temporarily attaching the projection to the rear face side; a second step of causing the horizontally laid external facing material 1 to which the heat insulation material 2 is temporarily attached in the first step, to face in an inclined shape and rotating the horizontally laid external facing material, while fitting a water upstream molding section 13 thereof into the water downstream molding section 12 of the horizontally laid external facing material 1 mounted on a roof surface; a third step of pressing a pressing section 24 of the heat insulation material 2 of the horizontally laid external facing material 1 mounted in the second step, sliding the pressing section to the water upstream side, and providing a rotational space in the next stage on the rear face side of the water downstream molding section 12 of the horizontally laid external facing material 1; and a fourth step of fixing a holding member 3 to the roof surface in a state in which the holding member is rotated and fitted so as to be arranged on the rear face side of the water downstream molding section 12 of the horizontally laid external facing material 1 mounted in the third step.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
