Description

Description: TECHNICAL FIELD The present invention relates to a method and a structure for constructing a heat-insulating roof including a roof folding plate and a heat-insulating panel arranged on the back side thereof.

[Conventional technology]

Conventionally, as a method of constructing a heat insulating roof, as shown in FIG. 17 and FIG. 18, a main beam 12 extending in a roof slope direction is used.
Are placed at intervals in the direction perpendicular to the roof slope,
The girders 13 extending in the direction perpendicular to the roof slope are arranged at intervals in the roof slope direction, and the ends of the girders 13 are connected to the main girder 12.
To form a roof frame 4, and a tight trapezoidal corrugated tight frame 14 is placed on the upper surface of the beam 13 and fixed by stud bolts or welding, and a screw rod 15 is welded to the top of the tight frame 14. Fixed by and beam 1
A plurality of heat-insulating panel receiving beams 1 extending in parallel with the 3
6, the heat insulating panel receiving beam 16 is fixed to the main beam 12, the roof heat insulating panel 8 made of glass wool board or the like is placed over the beam 13 and the heat insulating panel receiving beam 16, and the drill screw 17 is used. A method is known in which the roof folding plate 18 having a trapezoidal corrugated cross section is fixed, and the roof folding plate 18 is mounted over the tight frame 14, and the roof folding plate 18 is fixed to the tight frame 14 by a nut 19 screwed to the screw rod 15.

[Problems to be Solved by the Invention]

In the case of the conventional method, the supporting span of the roof folding plate 18 can be set to the large span L1, but the allowable supporting span of the heat insulating panel 8 is the small span L2. Therefore, the heat insulating panel receiving beam 16 needs to be installed and fixed. In addition, it is necessary to fix the heat insulation panel 8 to the heat insulation panel receiving beam 16 with the drill screw 17, and it is necessary to install a scaffold for performing the work. Further, when the roof folding plate 18 is attached, Since the heat insulation panel 8 has already been erected and fixed, the worker cannot confirm the position of the heat insulation panel receiving beam 16, so that when the worker rides in the middle of the allowable support span of the heat insulation panel 8, The strong heat insulation panel 8 may break and cause an accident. In order to eliminate this fear, it is necessary to install a roof folding plate attachment scaffold on the upper part of the heat insulation panel 8.

Further, since the heat insulating panel 8 is weak against rain, it is necessary to immediately install the roof folding plate 18 after the installation of the heat insulating panel 8 is completed. However, when the roof area is large, the installation of the heat insulating panel 8 is completed. It is difficult to immediately attach the roof folding plate 18 that covers the entire surface of the heat insulating panel 8.

The present invention eliminates the need for the heat insulating panel receiving beam and the work of fixing the heat insulating panel to the heat insulating panel receiving beam in the conventional roof heat insulating panel erection method, and installs the roof folding plate mounting work scaffold on the heat insulating panel.
