Description

Waterproof repair structure of roofing Technical Field The utility model relates to a repairing scheme of a leakage roof, in particular to a novel repairing scheme of concrete roof leakage. Background Roof water leakage is a common building problem, directly affects the quality of life of a house of a building owner at the top, and also affects the service life of a building. For the leakage problem of various roofs, different treatment measures are usually adopted, for example, local grouting treatment can be adopted for local cracks of cornices, gutter and the like, but for the severe leakage of roofs, for example, the leakage area is more than 70% of the area of the roof, the water leakage of the whole roof is serious, the ageing of a waterproof layer is serious, the whole roof is generally excavated and renovated, the waterproof coiled material is paved on the roof again in the conventional way, a layer of cement mortar is coated on the surface of the waterproof coiled material, and a protective layer is formed after hardening, so that the waterproof coiled material is prevented from being exposed to sunlight, and the ageing of the coiled material in the use process is delayed. For example, in the patent ZL201520463086.1 "a totally enclosed waterproof system for concrete construction engineering" in the prior art, a waterproof coiled material layer is paved on a top plate base surface of a building structure, and a 3-12 mm cement mortar protection layer is arranged on the waterproof coiled material layer. In order to reduce the absorption of solar radiation heat by a building, after the surface of the waterproof coiled material is coated with an interface treatment agent, a light-colored coating or a reflective heat-insulating coating layer is coated, for example, the method of embodiment 1 in a light-thin waterproof reflective heat-insulating energy-saving integrated system in a prior art patent ZL202221988896.5 is adopted, so that the waterproof coiled material can be protected like a cement mortar protection layer, and has a certain reflective heat-insulating function, but the coating is thinner, the adhesive force and the durability can be attenuated along with the use time, and the long-term reflective heat-insulating effect cannot be achieved, so that the conventional method is not suitable for roofing repair projects with limited load capacity and energy-saving requirements. Disclosure of utility model The utility model aims to solve the defects of the prior art and provides a novel roofing repairing scheme which is convenient to repair and construct and has the functions of waterproof, reflective and heat insulation. In order to achieve the above purpose, the present utility model adopts the following technical scheme: A roof waterproof repair structure comprises a cement mortar interface layer, a waterproof coiled material and a protective film, wherein the cement mortar interface layer, the waterproof coiled material and the protective film are sequentially arranged on a concrete roof; the cement mortar interface layer is formed by dry hardening cement mortar coated on the concrete roof; The waterproof coiled material is a double-sided adhesive waterproof coiled material and comprises a layer of tire base layer in the middle and adhesive layers respectively compounded on the two sides of the tire base layer; The protective film comprises a fluorocarbon composite film positioned on the surface layer and a butyl rubber self-adhesive layer compounded on the fluorocarbon composite film. The waterproof coiled material is characterized by further comprising an intermediate interface layer, wherein the intermediate interface layer is formed by a layer of plain cement paste coated between the protective film and the waterproof coiled material layer after being dried, cured and hardened. The thickness of the cement mortar interface layer is 3 mm-5 mm, the thickness of the waterproof coiled material is 1.2 mm-2 mm, and the thickness of the protective film is 0.4 mm-1.0 mm. After the technical scheme is adopted, compared with the background technology, the utility model has the following advantages: 1. Compared with the method of making a cement mortar protective layer on the surface of the waterproof coiled material, the method reduces the transportation of materials such as cement, sand and the like in the construction process and is more convenient for construction. The protective film paved on the outermost layer can protect the inner waterproof coiled material from sunlight irradiation, delay aging, and play a role in heat insulation of a building, and compared with the method of coating the light-colored coating protective layer on the outermost layer, the protective film has more excellent waterproofness and durability, and plays a role in truly insulating ultraviolet rays. 2. The outermost layer of the protective film is made of fluorine-containing resin, the lateral branches of the molecular str
