Description

Technical Field

[0001] The utility model relates to a building roof structure, in particular to a slope roof thermal insulation exhaust system. Background Art

[0002] For single-story and multi-story buildings, their roof structures have large-area slopes. Generally, an insulation layer is set on the sloping roof. For aesthetics, some buildings also have hanging tiles. When the insulation layer cannot be vented or the exhaust effect is not ideal after the sloping roof construction is completed, it is easy to cause the sloping roof insulation layer to expand and the concrete protective layer to become hollow. This not only affects the aesthetics, but also poses the risk of the hanging tiles sliding off as a whole, requiring secondary construction.

[0003] At present, the insulation layer is generally exhausted by an exhaust pipe, which is installed in an upward manner, that is, the end of the exhaust pipe extends upward from the insulation layer and the concrete protective layer. For a sloping roof, this arrangement is not only unsightly but also complicated to install. Utility Model Content

[0007] Preferably, the lower end of the exhaust pipe is connected to the pipeline through a 90° elbow and then extends to the gutter of the slope roof.

[0008] Preferably, the exhaust pipe is a PVC pipe.
