Description

Technical Field

[0001] This utility model relates to the field of roof waterproofing technology, and in particular to an inverted roof waterproofing structure. Background Technology

[0002] Inverted roof structures rely entirely on waterproofing materials for waterproofing. If the waterproofing material is of poor quality, the construction process is unsuitable for the site environment, or the waterproofing layer is not properly sealed to the structural layer, damage to the waterproofing layer during subsequent cross-construction work can lead to serious water leakage. Because the waterproofing layer is located below the insulation layer, it is difficult to find the leak point after seepage, and it may be necessary to remove the insulation and protective layers, resulting in a large workload and high repair costs.

[0003] Therefore, how to create a new inverted roof waterproofing structure is one of the important research and development topics at present. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an inverted roof waterproofing structure. By adding a waterproof coating layer using non-curing rubber asphalt waterproof coating, it can prevent cracking of the structural roof panel and improve the sealing between the waterproof membrane and the structural roof panel. At the same time, it also has a waterproofing function, thus comprehensively improving the roof waterproofing effect and overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides an inverted roof waterproofing structure, which consists of a waterproof coating layer, a waterproof membrane, an isolation layer, a thermal insulation layer, a waterproof and breathable layer, a concrete layer, an adhesive mortar layer, and a finishing layer arranged sequentially from bottom to top on the top surface of the structural roof panel. The waterproof coating layer is 2mm thick, and a non-curing rubber asphalt waterproof coating is applied inside the layer. The waterproof membrane is a double-layer SBS elastomeric modified bitumen waterproof membrane, model I, with each layer having a thickness of 3mm. The waterproof and breathable layer is made of a waterproof and breathable membrane.

[0006] As an improvement of this utility model, the slope of the top surface of the structural roof panel is 3%; The isolation layer is 0.1 mm thick and is made of polyethylene plastic film; The insulation layer is 70mm thick and is made of B1 grade extruded polystyrene board. The concrete layer is 50mm thick and is made of C20 fine aggregate concrete. A steel mesh with a diameter of 6mm and a bidirectional center-to-center spacing of 200mm is embedded in the layer. The bonding mortar layer is 20mm thick and uses DSM20 polymer cement mortar. The finishing layer is 10mm thick and uses light gray non-slip floor tiles with a solar radiation reflectance coefficient ≥0.4.

[0007] Furthermore, a parapet wall is provided above the structural roof panel, and the waterproof coating layer and waterproof membrane extend from the structural roof panel to the top of the parapet wall until they cover the top of the parapet wall.

[0008] Furthermore, the junction of the structural roof panel and the parapet wall is filled with an inside corner filler, which is arc-shaped and filled with cement mortar.

[0009] With this design, the present invention has at least the following advantages.

[0010] 1. A waterproof coating layer is added between the structural roof panel and the waterproof membrane. The waterproof coating layer uses non-curing rubber asphalt waterproof coating, which has three functions: First, the waterproof coating can penetrate into the gaps of the structural roof panel, giving the structural roof panel creep resistance and preventing cracking and deformation; second, after the structural roof panel is coated with waterproof coating, it can make the waterproof membrane adhere more firmly and improve the sealing performance; finally, the waterproof coating itself has a waterproof function, which can further improve the waterproof effect.

[0011] 2. Add a waterproof and breathable layer on top of the insulation layer. Use a waterproof and breathable membrane, which can not only waterproof the layer but also allow water vapor from the lower layer to drain through it.

[0012] 3. The waterproof membrane adopts a double-layer SBS elastomeric modified bitumen waterproof membrane, which covers the top of the structural roof panel all the way to the top of the parapet wall, forming a continuous and integrated waterproof structure and improving the waterproof effect.

Isolation layer; 7. Waterproof membrane; 8. Waterproof coating layer; 9. Corner filler; 10. Structural roof panel; 11. Parapet wall. Detailed Implementation

[0016] Please see Figure 1 This utility model provides an inverted roof waterproofing structure, including a structural roof panel 10, a parapet wall 11, an internal corner filler 9, a waterproof coating layer 8, a waterproof membrane 7, an isolation layer 6, a thermal insulation layer 5, a waterproof and breathable layer 4, a concrete layer 3, an adhesive mortar layer 2, and a finishing layer 1.

[0017] A parapet wall 11 is constructed on the structural roof panel 10, and a corner filler 9 is constructed at the junction of the structural roof panel 10 and the parapet wall 11. The corner filler 9 is commonly known as "smearing an eight" in traditional construction. Its interior is cement mortar, which is applied to the corner to form an arc transition. Its function is to prevent hollow areas from forming at the corner when the waterproof membrane 7 is pasted.

[0018] The top of the structural roof panel 10 is sloped at a gradient of 3%, and smoothed as it is poured.

[0019] From bottom to top, the structural roof panel 10 consists of a waterproof coating layer 8, a waterproof membrane 7, an isolation layer 6, an insulation layer 5, a waterproof and breathable layer 4, a concrete layer 3, an adhesive mortar layer 2, and a finishing layer 1.

[0020] The waterproof coating layer 8 is 2mm thick and is applied along the structural roof panel 12, the inside corner filler 9 and the parapet wall 11, all the way to the top of the parapet wall 11. It uses a non-curing rubber asphalt waterproof coating.

[0021] The waterproof membrane 7 is applied in two layers, each 3mm thick, along the structural roof panel 12, the internal corner filler 9, and the parapet wall 11, covering the top of the parapet wall 11. The waterproof membrane 7 is an SBS elastomeric modified bitumen waterproof membrane, model I, with polyester backing.

[0022] The isolation layer 6 has a thickness of 0.1 mm and is made of polyethylene plastic film.

[0023] The waterproof and breathable layer 5 is made of a waterproof and breathable membrane, which can not only provide waterproofing but also allow water vapor from the lower layer to drain through it. The insulation layer 4 is 70mm thick and is made of B1 grade extruded polystyrene board.

[0024] The concrete layer 3 is 50mm thick and is made of C20 fine aggregate concrete. A steel mesh with a diameter of 6mm and a bidirectional center-to-center spacing of 200mm is embedded in the layer.

[0025] The bonding mortar layer 2 is 20mm thick and uses DSM20 polymer cement mortar.

[0026] The finishing layer 1 is 10mm thick and uses light gray non-slip floor tiles with a solar radiation reflectance coefficient ≥0.4.

[0027] This utility model effectively improves the crack resistance of the structural roof panel and the sealing performance of the waterproof membrane by adding a waterproof coating layer, thus comprehensively improving the roof waterproofing effect. In addition, the addition of a waterproof and breathable layer allows water vapor from the lower layer to escape while waterproofing. The structure is reasonable, the construction is convenient, and it is suitable for widespread application.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
