STRUCTURE FOR REDUCING RAINFALL NOISE ON ROOF SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a structure for reducing rainfall noise on a roof surface, which is applicable to a roof film at a minimized construction cost while having an advantage such as the retainability of a lighting property and providing a sufficient noise reducing effect, and constructable even to an existing roof by work from the outdoor side. SOLUTION: A rope-like spacer member 4 is arranged at a prescribed interval along the upper surface of the roof film 2, and a fixing small piece film member 5 is provided at a prescribed interval on the rope-like spacer member 4 along the longitudinal direction. The fixing small piece film member 5 has a rope winding part 5a for inserting the spacer member 4 and a fixing flap 5b extended from the winding part 5a. The fixing flap 5b is connected to a mesh film 3, whereby the mesh film 3 is laid in a state that a prescribed space K is formed on the upper surface side of the roof membrane 2.
