[0002] Roofing is an important part of housing construction projects, among which roll waterproofing roofing is a widely used type of roofing. It is usually an economical, reliable, easy to install and maintain roof. However, after water seepage, the water vapor generated by the roll waterproofing roof cannot escape, causing bubbles and cracks to easily form on the thermoplastic base of the roll, especially in high temperature or high humidity weather, which in turn affects the durability and service life of the waterproof layer, resulting in higher maintenance and repair costs.

[0029] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0030] A waterproof breathing roof structure, such as Figure 1 As shown, it includes a bottom functional layer 2, which is laid on the roof; a slag filling layer 3, which is laid on the top surface of the bottom functional layer 2 and is in a compacted state; an upper functional layer 1, which is laid on the top surface of the slag filling layer 3; and an exhaust system 4, which includes an exhaust pipe 42, the lower end of which is arranged in the slag filling layer 3, and the upper end is a free end and extends out of the upper functional layer 1.

[0031] like Figure 1 and Figure 2 As shown, after water seepage occurs on the roof, the generated water vapor forms air convection through the "chimney effect" (air convection path 6), causing negative pressure to form inside the slag filling layer 3, thereby accelerating the timely discharge of water vapor along the exhaust system 4 (water vapor discharge path 5).

[0032] In the preferred embodiment, the upper functional layer 1 is composed of a waterproof membrane layer 11 and a cement mortar leveling layer 12 from top to bottom.

[0033] In this embodiment, the bottom functional layer 2 is preferably composed of a heat-insulating layer 21 and a gas barrier layer 22 from top to bottom.

[0034] By utilizing the structure of the waterproof breathing roof of the utility model, through the organic combination of the waterproof coiled material layer 11, the cement mortar leveling layer 12, the thermal insulation layer 21, the air barrier layer 22 and the exhaust system 4, the air barrier, thermal insulation and exhaust structures can be integrated into one, thereby improving the integrity and durability of the roof structure.

[0035] In the preferred embodiment, the exhaust system 4 also includes an exhaust channel 41, which is a channel with a certain extension length arranged in the slag filling layer 3, and the lower end of the exhaust pipe 42 is arranged in the exhaust channel 41, so that water vapor can be better gathered in the exhaust pipe 42 to improve the exhaust efficiency.

[0036] In the preferred embodiment of the present invention, the exhaust passage 41 is a passage built with bricks. Bricks themselves have the characteristics of low cost, high compressive strength, and porous structure, so that the passage built with bricks is cheap, durable, and has strong moisture absorption capacity.

[0037] In this embodiment, the exhaust pipe 42 is preferably 2 -40m 2 Set one up.

[0038] In this embodiment, preferably, the total height of the exhaust pipe 42 is 0.8 m-1 m.

[0039] In this embodiment, preferably, one end of the exhaust duct 42 connected to the atmosphere, and the upper end of the exhaust duct 42 is bent and opened downward.

[0040] The exhaust duct 42 is preferably arranged at intervals, with a height and an opening facing downward to improve the exhaust efficiency and reduce the negative impact of the exhaust duct 42 itself. For example: if the duct is too low, rainwater is likely to splash into the exhaust duct 42; if the duct is too high, the windward area is large, resulting in large wind resistance and instability, and easy swaying; other openings are facing in a direction that makes it easier for rainwater to enter, etc.

[0041] In the preferred embodiment, a water stop ring 43 is provided on the exhaust pipe 42. The water stop ring 43 extends the water infiltration path several times, thereby greatly increasing the infiltration resistance to achieve the purpose of anti-seepage.

[0042] In the preferred embodiment, the exhaust duct 42 is provided with tie bar anchors 44 and is stabilized in the slag filling layer by the tie bar anchors 44. The tie bar anchors 44 make the slag filling layer 3 and the exhaust duct 42 form a force-bearing whole, and the connection is more stable.

[0043] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
