Description

Technical Field

[0001] The utility model belongs to the technical field of construction, in particular to a high crack-resistant roof waterproof and thermal insulation structure. Background Art

[0002] The roof waterproofing and thermal insulation structure is related to the living environment and living conditions of people. It is an extremely important part of building protection and has a decisive influence on the durability and service life of the building.

[0003] The leveling layer and protective layer of the traditional roof waterproofing and insulation structure are both made of cement mortar. The cement mortar has insufficient adhesion. After being exposed to the sun and rain for a long time, the protective layer is very easy to crack, causing roof leakage. At the same time, water vapor entering the insulation layer will also affect the insulation effect of the insulation layer.

[0004] In addition, in order to ensure the strength of the traditional roof waterproofing and thermal insulation structure, the leveling layer and the protective layer are designed to be thicker, which causes the structural layer to bear greater pressure and consume more materials. At the same time, for the sake of aesthetics, it is necessary to apply a layer of acrylic reflective paint on the surface of the protective layer, which takes a long time to construct. Utility Model Content

[0005] The main purpose of the utility model is to propose a highly crack-resistant roof waterproof and thermal insulation structure, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A highly crack-resistant roof waterproof and thermal insulation structure comprises a slope layer arranged on the top of a structural layer, a high-ductility concrete leveling layer is arranged on the top of the slope layer, two layers of waterproof coatings are applied on the top of the high-ductility concrete leveling layer, a waterproof coiled material is arranged on the top of the two layers of waterproof coatings, an insulation layer is arranged on the top of the waterproof coiled material, and a high-ductility concrete protective layer is arranged on the top of the insulation layer.

[0008] Preferably, a cast-in-place concrete plug is provided on the edge of the thermal insulation layer on the waterproof coiled material, and a waterproof sealant is provided between the cast-in-place concrete plug and the high-ductility concrete protective layer.

[0009] Preferably, the material of the slope leveling layer is lightweight aggregate concrete.

[0010] Preferably, the waterproof coating is a water-based rubber asphalt waterproof coating.

[0011] Preferably, the waterproof membrane is a polymer-modified asphalt waterproof membrane.

[0012] The utility model provides a highly crack-resistant roof waterproof and thermal insulation structure, which has the following beneficial effects:

[0013] 1. The high-ductility concrete leveling layer and the high-ductility concrete protective layer of the utility model are both high-ductility concrete, which have high strength, high toughness, high crack resistance and high damage resistance. The high-ductility concrete protective layer is not easy to crack, which greatly improves the anti-leakage ability of the roof and ensures the thermal insulation effect of the thermal insulation layer.

[0014] 2. The thickness of cement mortar in traditional protective layer and leveling layer is 3-4cm, while the thickness of high-ductility concrete protective layer and high-ductility concrete leveling layer of the utility model can reach 1-1.5cm, which reduces consumables and reduces the pressure on the structural layer. At the same time, high-ductility concrete has the advantages of being beautiful and requiring no decoration. It can also save acrylic reflective coating on the surface of high-ductility concrete protective layer, saving construction time. BRIEF DESCRIPTION OF THE DRAWINGS
