Description

Technical Field

[0001] The utility model relates to the technical field of house repair, in particular to a waterproof layer structure used for repairing old houses. Background Art

[0002] The repair and waterproofing of old houses is one of the key tasks of old house renovation. Among the existing patent technologies, the publication number (CN210049291U) discloses a basement waterproof structure, including an exterior wall, an interior layer, and a waterproof layer. A waterproof layer is provided between the exterior wall and the interior layer, and the waterproof layer is coated with a cement-based penetrating crystallized waterproof coating; a mesh cloth is provided between the two waterproof layers. The waterproof layer structure in the above patent technology is a common waterproofing method.

[0003] However, the patented waterproof structure still has the following disadvantages: 1. The waterproof layer is formed by two layers of cement-based penetrating crystallization waterproof coating layers and a mesh cloth layer located between the two layers of cement-based penetrating crystallization waterproof coating layers. The provided cement-based penetrating crystallization waterproof coating layer can enhance the rigidity of the base surface layer, but due to the unreasonable arrangement of the mesh cloth, such a layer structure is still prone to blistering and peeling in a blistering environment; 2. The use of two layers of cement-based penetrating crystallization waterproof coating layers alone for waterproofing does not achieve the required waterproofing effect and is also unable to effectively prevent moisture from overflowing; 3. It is a purely rigid waterproofing layer, and is prone to cracking and leakage when used in areas with complex environments such as roofs and terraces.

[0004] Therefore, how to design a waterproof layer structure for repairing old houses that is simpler and more reasonable, can better avoid bubbling and peeling, can improve the waterproof effect and prevent moisture overflow, has become a technical problem to be solved by technical personnel in this field. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is how to design a waterproof layer structure for repairing old houses which is simpler and more reasonable, can better avoid bubbling and peeling, can improve the waterproof effect and avoid moisture overflow.

[0006] To achieve the above-mentioned purpose, the utility model provides a waterproof layer structure for repairing old houses, comprising a base surface layer and a concrete mortar layer, with a waterproof layer arranged between the base surface layer and the concrete mortar layer; characterized in that the waterproof layer comprises a cement-based penetrating crystallizing self-healing coating layer, an asphalt waterproof coating layer is arranged on the cement-based penetrating crystallizing self-healing coating layer, and a mesh cloth layer is arranged on the asphalt waterproof coating layer.

[0007] In this way, by arranging a cement-based penetrating crystallization self-healing coating layer on the base surface layer, the cement-based penetrating crystallization self-healing coating layer can improve the rigidity of the base surface layer, making the base surface layer more solid, and can better prevent moisture from below the base surface layer from overflowing upward; and then by arranging an asphalt waterproof coating layer, the waterproof effect can be improved; finally, mesh cloth layers are arranged, and the mesh cloth layer is arranged on the top layer. The mesh cloth layer can cooperate with the asphalt waterproof coating layer to improve the adhesion of the entire structure, so that the entire waterproof structure can better cope with the water environment and can better prevent the waterproof layer from bubbling and peeling.

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

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

[0010] As an optimization, the mesh cloth layer is polyester mesh cloth, glass fiber mesh cloth or alkali-resistant fiber mesh cloth.

[0011] In this way, the mesh cloth is made of polyester mesh cloth, glass fiber mesh cloth or alkali-resistant fiber mesh cloth, the material selection is more reasonable and the cost is lower.

[0012] As an optimization, the cement-based infiltration crystallization self-healing coating layer includes a first cement-based infiltration crystallization self-healing coating layer, and also includes a second cement-based infiltration crystallization self-healing coating layer arranged on the first cement-based infiltration crystallization self-healing coating layer.

[0013] In this way, by designing the cement-based penetrating crystallization self-healing coating layer into a first layer of cement-based penetrating crystallization self-healing coating layer and a second layer of cement-based penetrating crystallization self-healing coating layer, the two layers are constructed separately, which can better enhance the rigidity of the base surface layer and better prevent moisture overflow.

[0014] As an optimization, the thickness of the waterproof layer is 3-5 mm.

[0015] In this way, the thickness design of the waterproof layer is more reasonable, which can not only achieve waterproof and moisture-proof effects, but also save materials.

[0016] In summary, the waterproof layer structure used for the renovation of old houses, through the design of the layer structure, sets the mesh cloth layer on the top layer, and penetrates the crystallized high polymer modified asphalt waterproof coating, so that the mesh cloth forms a layer of reinforcing carcass skeleton in the coating, so that the waterproof layer has better strength and tensile crack resistance, and better durability and water resistance. And the use of cement-based penetrating crystallization self-healing coating and penetrating crystallization high elastic polymer modified waterproof asphalt can better avoid bubbling and peeling, improve the waterproof effect and prevent moisture overflow.
