Embodiment Construction

[0019] Referring to the embodiment shown in Figure 1, this thermal insulation and waterproof roof air-inducing drainage system includes the following layers from bottom to top: reinforced concrete roof panel 14, plain cement slurry layer 13, first cement mortar leveling layer 12, elastic waterproof layer 11. The second cement mortar leveling layer 10, thermal insulation layer 9, rigid waterproof layer 8, fine stone concrete layer with reinforced mesh inside 7, facing layer 6, and the parapet wall 3 is horizontally penetrated on the facing layer 6, downward Connecting the rainwater pipe 2, it is characterized in that: there is no vertical air outlet pipe, and the air-inducing drainage pipe 1 is arranged from the inside of the insulation layer to the side relative to the rainwater pipe. .

[0020] The horizontal downward slope of the bleed air drainage pipe 1 is any value between 1% and 3%, for example, 2%. The bleed air drain pipe 1 can be made of stainless steel, PVC, corrosi...

Abstract

The present invention is air leading and water draining system for heat insulating waterproof roof and its construction process. The air leading and water draining system includes a reinforced concrete roof slab layer, a plain cement slurry layer, a first leveling cement mortar layer, an elastic waterproof layer, a second leveling cement mortar layer, a heat insulating layer, a rigid waterproof layer, a fine stone concrete layer, a veneer layer, and transverse parapet connected to the lower rain water pipe successively arranged from bottom to top. It features the inclined air leading and water draining pipe passing through the parapet and communicated to the rain water pipe, and no vertical ventilating pipe. The present invention makes it possible for water permeating to the heat insulating layer to flow easily into the rain water pipe so as to avoid leakage.

Description

(1) Technical field [0001] The invention relates to a thermal insulation roof of a building and a construction method thereof. (2) Background technology [0002] Roof leakage is a common problem that has plagued the construction industry for a long time. When the roof leaks, it is very difficult to repair the roof with insulation layer, because the top of the leak point is not necessarily the place where the waterproof layer has problems, and the water that leaks from the waterproof layer Flowing in the insulation layer, the non-hydrophobic insulation material can also absorb more water, even the hydrophobic insulation material can still hold a certain amount of water, when it accumulates and flows to a certain impermeability difference in the structural layer There is a phenomenon of leakage into the room. Sometimes rainy days don't leak and sunny days leak. It is more difficult to find and repair the leakage point of this waterproof layer. If there is a protective layer...
