Description

  The present invention relates to a folded plate roof and a manufacturing method thereof, and more particularly to a folded plate roof structure when a folded plate roof constituting a ceiling of a building is repaired and a manufacturing method thereof.

  Folded plate roofs may become obsolete when used for a long time, causing problems such as rain leaks. For this reason, it is preferable to repair after a certain period of time has elapsed since construction.

  FIG. 7 is a schematic perspective view showing a configuration of a folded plate roof structure when a conventional folded plate roof is renovated as shown in Patent Document 1, and FIG. 8 is a view of VIII shown in FIG. It is sectional drawing of a -VIII line.

  With reference to these drawings, fixed-size heat insulating materials 63a to 63c are installed on the upper surface of the folded plate roof 15 where the convex portions 16 and the concave portions 17 appear alternately. It is fixed to the roof 15. Each of the heat insulating material 63a to the heat insulating material 63c is composed of a urethane foam plate-like panel.

A waterproofing sheet 65 made of vinyl chloride is spread over the entire upper surface of the heat insulating material 63a to the heat insulating material 63c. Even if the folded plate roof 15 is aged due to this, the heat insulating effect and the waterproof effect are provided by repairing the folded plate roof 15.
