Description

Technical Field

[0001] This utility model relates to the field of building repair technology, and in particular to a rigid-flexible composite self-healing waterproof layer structure for building roofs and balconies. Background Technology

[0002] Waterproofing the renovation of old houses, balconies, and terraces is one of the key tasks in the renovation of old buildings. Existing patent technology, publication number (CN210049291U), discloses a basement waterproofing structure, including an exterior wall, an interior layer, and a waterproof layer. A waterproof layer, made of cement-based penetrating crystalline waterproof coating, is placed between the exterior wall and the interior layer; a mesh fabric is placed between the two waterproof layers. To address the shortcomings of the above patent technology, the applicant previously applied for patent publication number (CN222614902U) for a waterproof layer structure for the renovation of old houses, including a base layer and a concrete mortar layer, with a waterproof layer placed between the base layer and the concrete mortar layer; the waterproof layer includes a cement-based penetrating crystalline self-healing coating layer, an asphalt waterproof coating layer is placed on the cement-based penetrating crystalline self-healing coating layer, and a mesh fabric layer is placed on the asphalt waterproof coating layer. This structure can better prevent blistering and peeling, and can improve the waterproofing effect to prevent moisture leakage.

[0003] However, during the process of technology research and development and practical application, the applicant discovered the following shortcomings in the above structure: 1. The top layer of the waterproof layer is relatively soft and has poor resistance to damage; 2. The waterproof layer structure has a relatively simple functional design and still has the risk of penetration.

[0004] Therefore, how to provide a rigid-flexible composite self-healing waterproof layer structure for building roofs and balconies with a simple and reasonable structural design that can better form multiple waterproof functions and further improve waterproof reliability has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to provide a rigid-flexible composite self-healing waterproof layer structure for building roofs and balconies with a simple and reasonable structural design that can better form multiple waterproof functions and further improve the reliability of waterproofing.

[0006] To achieve the above objectives, this utility model provides a rigid-flexible composite self-healing waterproof layer structure for building roofs and balconies, comprising a base layer and a concrete mortar layer, with a waterproof layer disposed between the base layer and the concrete mortar layer; characterized in that the waterproof layer comprises a first rigid waterproof layer, a flexible waterproof layer and a second rigid waterproof layer arranged sequentially from bottom to top; the flexible waterproof layer comprises an asphalt waterproof coating layer, with a mesh fabric layer disposed on the asphalt waterproof coating layer.

[0007] Thus, the aforementioned rigid-flexible composite self-healing waterproof layer structure for building roofs and balconies incorporates a first rigid waterproof layer, a flexible waterproof layer, and a second rigid waterproof layer, forming a multi-layered waterproofing system combining rigidity, flexibility, and rigidity. The overall waterproofing structure exhibits better rigidity, effectively preventing damage and mitigating moisture buildup from the substrate. Furthermore, the flexible waterproof layer, comprising an asphalt waterproof coating layer and a mesh fabric layer, along with the upper second rigid waterproof layer, enhances the overall adhesion of the structure, enabling it to better withstand water immersion and preventing blistering and peeling. This further improves the reliability of the waterproofing.

[0008] As an optimization, the asphalt waterproof coating layer is a penetrating crystalline high-elastic polymer modified waterproof asphalt layer.

[0009] In this way, the asphalt waterproof coating layer uses a penetrating crystalline high-elastic polymer modified waterproof asphalt layer, which can improve the waterproof effect.

[0010] As an optimization, the asphalt waterproof coating layer includes a first asphalt waterproof coating layer, a second asphalt waterproof coating layer, a third asphalt waterproof coating layer, and a fourth asphalt waterproof coating layer arranged vertically in a stacked manner; and the mesh fabric layer is arranged between the first asphalt waterproof coating layer and the second asphalt waterproof coating layer or between the second asphalt waterproof coating layer and the third asphalt waterproof coating layer.

[0011] In this way, the flexible waterproof layer forms a four-coat-one-fabric structure, which makes the structural design of the flexible waterproof layer more reasonable, improves the waterproof reliability, and makes the arrangement of the mesh fabric layer more reasonable.

[0012] As an optimization, the mesh fabric layer is a polyester mesh fabric, a fiberglass mesh fabric, or an alkali-resistant fiber mesh fabric.

[0013] In this way, the selection of materials such as polyester mesh, fiberglass mesh, or alkali-resistant fiber mesh is more reasonable and the cost is lower.

[0014] As an optimization, the first rigid waterproof layer includes a first high weather-resistant emulsion layer and a second high weather-resistant emulsion layer disposed on the first high weather-resistant emulsion layer.

[0015] In this way, the first rigid waterproof layer is formed by the first high weather-resistant emulsion layer and the second high weather-resistant emulsion layer. The structural design is more reasonable, which can better improve rigidity and waterproof effect.

[0016] As an optimization, the second rigid waterproof layer includes a third high weather-resistant emulsion layer and a fourth high weather-resistant emulsion layer disposed on the third high weather-resistant emulsion layer.

[0017] In this way, the design of the second rigid waterproof layer is more reasonable, which can better improve rigidity and achieve better waterproofing effect.

[0018] As an optimization, a waterproof and seepage-resistant mortar repair layer is also provided on the base layer; a protective layer is provided on the waterproof and seepage-resistant mortar repair layer, which is a penetrating sand-fixing agent layer or an SK penetrating crystallizing waterproof agent layer.

[0019] In this way, when treating old roofs, a combination of waterproof and seepage-resistant mortar repair layer and penetrating sand-fixing agent layer is used; when treating new roofs, a combination of waterproof and seepage-resistant mortar repair layer and SK penetrating crystallizing waterproof agent layer is used. After this treatment, the structural waterproofing effect formed by the first rigid waterproof layer, the flexible waterproof layer and the second rigid waterproof layer is better.

[0020] As an optimization, the thickness of the waterproof layer is 7-10 mm.

[0021] This allows for a more reasonable design of the waterproof layer's thickness range. Furthermore, the thickness of the waterproof layer is 8mm.

[0022] In summary, the rigid-flexible composite self-healing waterproof layer structure for building roofs and balconies described above forms multiple layers of waterproofing, including rigid, flexible, and rigid composite layers, which can better achieve multiple waterproofing functions and further improve waterproofing reliability.
