Description
Technical Field
The utility model relates to the field of roof waterproofing, in particular to a rigid-flexible combined waterproof system suitable for roof waterproofing engineering in newly-built, expanded and reconstructed industrial and civil buildings.
Background
The leakage rate of the roof of the house building is high, and the use function of the house is seriously influenced. Except for the reasons of improper construction measures, more importantly, problems occur in material selection and construction, so that the phenomena of annual leakage, annual repair and annual leakage occur.
The traditional roof waterproof is generally made of organic waterproof coiled materials and organic waterproof coatings, the aging resistance of the organic materials can not be thoroughly solved, the service life of the organic materials is difficult to reach the same service life as that of a building, and the service life of the current best roof waterproof coiled material is generally not longer than 15 years. And the reliability problem of the coil adhesion is difficult to be solved completely, which is 20,000m2For example, the length of the hot-melting lap joint plane of the coiled material reaches 40 kilometers, and the coiled material is almost impossible to ensure that no tiny leakage exists. In addition, the problems of water leakage and repairability after the waterproof roll is stripped from the bottom plate and is locally damaged are also extremely difficult to solve.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: in order to overcome the defects in the prior art, a rigid-flexible waterproof system is provided.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a rigid-flexible combined waterproof system comprises a waterproof coating interface layer and a flexible inorganic surface layer, wherein the waterproof coating interface layer and the flexible inorganic surface layer are arranged on a roof concrete layer from bottom to top. Wherein, the waterproof coating interface layer and the flexible inorganic surface layer are both pure inorganic materials, the durability is super-good, the service life is the same as that of a building, and the endurance life is over 70 years.
The waterproof coating interface layer is formed on the roof concrete layer through spraying or plastering and pressing. Specifically, the waterproof coating interface layer adopts a rapid hardening cement-based permeable crystallization waterproof coating, and compared with an organic waterproof coating, the waterproof coating has the permeable crystallization performance which is not possessed by the organic waterproof coating. Can be combined with the lower layer material to form a compact anti-permeability area, thereby greatly improving the anti-permeability capability of the whole structure. The rapid-hardening cement-based permeable crystallization waterproof coating can be sprayed or troweled and pressed to be formed on the whole roof at one time, the whole surface is seamless, complex lap joint is not needed, the construction speed is ultrahigh, and the waterproof quality is reliable.
The flexible inorganic surface layer is formed on the waterproof coating interface layer through spraying or smearing and pressing. Compared with an organic waterproof coiled material, the flexible inorganic surface layer is made of the ultrahigh-toughness energy-absorbing energy-consuming cement-based composite material, can be formed on the whole roof by one-step spraying or plastering and pressing, is seamless in the whole surface, does not need complicated lap joint, and is ultrahigh in construction speed and reliable in waterproof quality; in addition, because the cement-based composite material with ultrahigh toughness, energy absorption and energy consumption is reinforced by the high-strength high-toughness high-modulus bulletproof fibers and the carbon nano tubes, the cement-based composite material has ultrahigh toughness and flexibility, the elongation of the cement-based composite material is 8-12%, the elongation of steel is 9-10%, the performance of the cement-based composite material is comparable to that of steel, but the cement-based composite material has the performance which cannot be achieved by steel bars, namely never rusting; in addition, the tensile strength of the ultra-high toughness energy-absorbing energy-consuming cement-based composite material is greater than 9MPa and is 8 times that of the waterproof coiled material; the compressive strength is 50MPa, which is 50 times of that of the waterproof coiled material; the mechanical property is extremely excellent.
The roof concrete is common concrete such as C30 or C25.
The thickness of the waterproof coating interface layer is 1.2-1.5mm, and the rapid-hardening cement-based permeable crystallization waterproof coating is an inorganic rapid-hardening cement-based permeable crystallization waterproof coating. The single-component model is adopted, so that the use is convenient, and the use effect is better when the double-component model is adopted.
The thickness of the flexible inorganic surface layer is 15-20 mm. The traditional waterproof coiled material has too many lap joints, the ultrahigh-toughness energy-absorbing energy-consuming cement-based composite material flexible inorganic surface layer is formed once, the waterproof performance is better, and the problem of easy leakage of a roof is thoroughly solved.
Furthermore, a bonding mortar layer and a heat-insulating layer are arranged between the roofing concrete layer and the waterproof coating interface layer from bottom to top.
Furthermore, the waterproof coating interface layer is formed on the heat-insulating layer through spraying or smearing and pressing.
Furthermore, after the roof concrete layer is poured, the fixing piece is paved on the surface of the roof concrete layer, and then the bonding mortar layer and the heat insulation layer are poured.
Further, the mounting include the stationary plane that bottom surface and roofing concrete layer flush, locate stationary plane apex angle department and the extension section that the stationary plane flushed, locate stationary plane apex angle department and stationary plane vertically canned paragraph.
Preferably, the fixed surface adopts regular hexagon structure, and the mounting structure is more firm.
Further, the upper surface and the lower surface of stationary plane are located to the canned paragraph interval for the junction of the upper surface of stationary plane and lower surface all forms the triangle-shaped structure, and overall connection structure is more firm.
Furthermore, the upper end of the fixed section arranged on the upper surface of the fixed surface is positioned in the heat insulation layer, and the lower end of the fixed section arranged on the lower surface of the fixed surface is positioned in the roof concrete layer.
The heat-insulating layer, the bonding mortar layer and the roof concrete layer are connected through the fixing piece, and the stability of the bottom layer structure is ensured.
Through the mounting, the connectivity of whole waterproof system is strengthened for overall structure is more reliable firm.
The utility model has the beneficial effects that: the super-durable rigid-flexible combined waterproof system has mechanical properties, and meanwhile, the waterproof performance, the waterproof life, the durability and the reliability are obviously improved. Compared with the traditional method, the method has fewer processes, no seam exists on the whole surface, the mechanical spraying construction can be realized, and the construction period and the comprehensive cost are lower.
