ROOFING STRUCTURE (VARIANTS) Russian patent published in 2005 - IPC

FIELD: building, particularly roofing structures.

SUBSTANCE: roofing structure comprises roof base and polymer-bitumen roof coating made of overlapped roll material strips laid in rows upon roof base through the full building length. Coating includes the first row of roll material strips laid near parapet wall. The strips are overlapped and connected with each other along roof length by fusing thereof. Strips of next rows are also overlapped and connected by strip fusing through roof length and each next row is overlapped and connected to edges of previous row by fusing thereof. Edges of previous row facing next row are connected in points to roof base by means of fastening members spaced in row length direction. All roll material strips of each row are freely laid on roof base to define air gaps communicating with each other and located between roll material and smoothed roof base surface. Connection of overlapped strip areas is performed so that connection areas enclose areas of fastening members location. Roll material strip extending over parapet wall is fused on other roll material strips located in parapet wall area. Edge of the roll material strip overlapping parapet wall is connected to parapet wall by fastening members spaced in parapet wall length direction so that air gaps are formed in-between.

EFFECT: improved venting ability of roof structure.
