Description

Technical Field

[0001] The utility model belongs to the field of construction, and in particular relates to a waterproof, heat-insulating and breathable roof structure. Background Art

[0002] At present, the bottom surface of the roof is usually paved with concrete, but because the concrete is exposed to the outdoors and is often exposed to rain and sunlight, the concrete is prone to powdering, which greatly reduces the service life of the roof. After long-term use, rainwater easily penetrates through the concrete to the top floor, causing the ceiling of the top floor to leak. In addition, in summer, sunlight shines on the roof ground, causing the ground temperature to rise, and the heat of the ground will be transferred to the top floor, causing the indoor temperature of the top floor to rise, and the comfort of the residents is poor. In order to improve the drainage performance of the roof, application number 201822246493.3 discloses a new waterproof thermal insulation layer, which is provided with a tile layer, an extruded polystyrene foam plastic layer and a first glass fiber mesh cloth layer to achieve the effect of waterproofing and heat insulation. However, when this type of waterproof thermal insulation layer is used, the extruded polystyrene foam plastic layer is prone to aging in a long-term high temperature and high humidity environment, has poor weather resistance, and is prone to dents; the waterproof and heat insulation effect is also greatly affected after the tile layer is cracked.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1-2. The waterproof, heat-insulating and breathable roof structure includes a waterproof layer 1, a foamed ceramic layer 2 and a surface layer 3. The waterproof layer 1, the foamed ceramic layer 2 and the surface layer are arranged in sequence from bottom to top. The foamed ceramic layer 2 includes a plurality of foamed ceramic sheets 22. There are gaps 21 between adjacent foamed ceramic sheets 22. The gaps 21 are interconnected and connected to the outside atmosphere. In the actual construction process, the surface layer 3 is composed of ceramic tiles; the waterproof layer 1 is formed by laying high-temperature resistant cement mortar; the foamed ceramic layer 2 is formed by laying a plurality of foamed ceramic sheets 22, and there are gaps 21 between adjacent foamed ceramic sheets 22. Through the interconnected gaps 21, the drainage function can be achieved to prevent water from accumulating under the surface layer 3; and the gaps 21 are used to achieve communication with the outside atmosphere. When it is hot, the air in the gaps is discharged, and when it is cold, the air in the atmosphere is inhaled, which plays a ventilation role, effectively preventing high and low pressures from damaging the waterproof layer and preventing the surface layer 3 from arching upward. Specifically, since the gap 21 is connected to the outside atmosphere, the air pressure in the gap 21 is kept consistent with the atmospheric pressure, effectively avoiding excessive pressure difference between the inner and outer end surfaces of the surface layer 3, thereby helping to ensure the service life of the surface layer 3 and greatly reducing cracking of the surface layer 3.

[0017] When the waterproof, heat-insulating and breathable roof structure of the utility model is used, the foamed ceramic layer 2 plays a role of light weight, waterproof and heat insulation, thereby greatly reducing the possibility of water entering the waterproof layer 1 through the foamed ceramic layer 2; through the heat insulation effect of the foamed ceramic layer 2, the heat on the surface layer 3 is greatly reduced. Conducting to the waterproof layer 1, thereby playing a heat insulation role for the roof of the house. Similarly, it also effectively prevents the low temperature of the surface layer 3 from being conducted to the waterproof layer 1 and the roof, playing a heat preservation role.

[0018] The waterproof layer 1 and the foamed ceramic layer 2 are connected by a water-resistant adhesive layer 4. The water-resistant adhesive layer 4 can be made of water-resistant tile glue to achieve a waterproof effect and reduce the penetration of external water through the gaps between the tiles on the surface layer 3.

[0019] The foamed ceramic layer 2 and the surface layer 3 are connected by a heat-resistant adhesive layer 5. The heat-resistant adhesive layer 5 can be made of heat-resistant tile adhesive to prevent heat and reduce the heat from being transferred downward to the waterproof layer 1.

[0020] like Figure 1 to Figure 3 As shown, the waterproof, heat-insulating and breathable roof structure also includes a floor drain 6 , which includes a first floor drain pipe 61 and a second floor drain pipe 62 . The first floor drain pipe 61 is connected to the gap 21 , and the second floor drain pipe 62 is connected to the surface layer 3 .

[0021] The water inlet end of the second floor drain pipe 62 is higher than the water inlet end of the first floor drain pipe 61, the inner diameter of the first floor drain pipe 61 is larger than the outer diameter of the second floor drain pipe 62, and the lower end of the second floor drain pipe 62 is located in the first floor drain pipe 61 and communicates with the first floor drain pipe 61. In actual use, the water in the second floor drain pipe 62 can flow into the first floor drain pipe 61 and be drained through the first floor drain pipe 61, thereby preventing water from accumulating on the roof and ensuring the waterproof effect of the entire roof structure.

[0022] Since the lower end of the second floor drain pipe 62 is located in the first floor drain pipe 61, the water on the surface layer 3 directly enters the first floor drain pipe 61 through the second floor drain pipe 62, so that the water is quickly drained away. Since the inner diameter of the first floor drain pipe 61 is larger than the outer diameter of the second floor drain pipe 62, the water in the gap 21 can flow away smoothly through the first floor drain pipe 61.

[0023] At the same time, since the lower end of the second floor drain pipe 62 is located inside the first floor drain pipe 61, the gas in the gap 21 can be connected to the outside atmosphere through the gap between the first floor drain pipe 61 and the second floor drain pipe 62, and can also be connected to the outside atmosphere through the second floor drain pipe 62, thereby balancing the atmospheric pressure.

[0024] The foamed ceramic layer 2 includes a plurality of foamed ceramic sheets 22, and there is a gap of about 5 to 10 mm between adjacent foamed ceramic sheets 22, forming a gap 21. The gaps 21 may be connected by a connecting pipe, or the gaps between the foamed ceramic sheets 22 may be directly connected when the foamed ceramic sheets 22 are laid, so that the gaps 21 are connected to the outside atmosphere to balance the air pressure.

[0025] The waterproof, heat-insulating and breathable roof structure of the utility model further includes a water-blocking board 7, which is arranged on the periphery of the waterproof layer 1 and extends upward to the top of the surface layer 3. The heat-insulating board 7 and the waterproof layer 1 can be laid at the same time, and the material is the same as that of the waterproof layer 1. The top of the water-blocking board 7 is higher than the upper end surface of the surface layer 3, thereby effectively preventing the external water from flowing downward through the side of the surface layer 3, and further ensuring the waterproof effect of the overall structure.

[0026] The first drainage hole and the second drainage hole are respectively provided on the waterproof layer 1 and the surface layer 3, the first floor drain pipe 61 is connected to the first drainage hole, and the second floor drain pipe 62 is connected to the second drainage hole. In actual construction, multiple first drainage holes and second drainage holes can be provided, and the number of the first drainage holes and the second drainage holes can be increased or decreased according to the actual area of ​​the waterproof layer 1 and the surface layer 3, so that the accumulated water on the surface layer 3 can be quickly drained away; and the gaps 21 at various locations can be quickly connected to the outside atmosphere, and the accumulated water can be discharged.

[0027] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
