Referring to fig. 1, the present invention provides a waterproof structure 100 for a building, which comprises a fiber concrete base layer 10, a polyurea waterproof layer 20, a rigid foam polyurethane heat insulation waterproof layer 30 and a polymer mortar layer 40, which are connected in sequence; the polyurea waterproof layer 20 is formed by spraying polyurea waterproof material on the fiber concrete base layer 10, and the hard foam polyurethane heat-preservation waterproof layer 30 is formed by spraying hard foam polyurethane heat-preservation waterproof material on the polyurea waterproof layer 20. The fiber concrete has higher strength, and when the fiber concrete is designed into irregular shapes such as curved surfaces, special shapes and the like, the interior of the concrete base layer still can keep the original structure, so that the integral waterproof structure cannot be damaged, and the fiber concrete has higher waterproof and heat-insulating properties after the polyurea waterproof layer, the hard foam polyurethane heat-insulating waterproof layer and the polymer mortar layer are added; the polyurea waterproof layer and the hard foam polyurethane heat-insulation waterproof layer are formed in a spraying mode, and can be prepared into irregular shapes such as curved surfaces, special shapes and the like, so that the individual requirements of users are met.
The waterproof structure 100 for a building can be installed on the outer roof of the building.
The fiber concrete base layer 10 is a composite material consisting of fibers and a cement base material (cement stone, mortar or concrete).
In one embodiment, the fibers are short fibers having a certain aspect ratio (i.e., the ratio of the length to the diameter of the fibers), i.e., the fiber concrete base 10 is a short fiber concrete base.
The short fiber can be one or more of steel fiber, glass fiber and polypropylene fiber. That is, the fiber concrete can be formed by adopting steel fibers, glass fibers or polypropylene fibers to be singly matched with a cement base material, and also can be formed by adopting one, two or three fibers to be matched with the cement base material.
In one embodiment, the fiber concrete base layer 10 is formed by mixing steel fibers and a cement base material in a weight ratio of 0.5: 9.5.
The manufacturing process of the polyurea waterproof layer 20 specifically comprises the following steps: after the fiber concrete base layer 10 is manufactured, the polyurea waterproof material is directly sprayed on the outer layer or the surface of the fiber concrete base layer 10 by using spraying equipment such as a spray gun. The spraying mode can form a curved surface and a special-shaped waterproof structure, the waterproof structure is more convenient to form, and the general mode is difficult to form irregular shapes such as a curved surface and a special shape.
In one embodiment, the polyurea waterproof layer 20 has a thickness of 1.5mm to 2.5 mm. The polyurea waterproof layer 20 with the thickness can be matched with the fiber concrete base layer 10 to realize a better waterproof effect, and the integral waterproof effect is ensured on the premise of less material consumption. And a common concrete base layer is adopted, and the thickness of the waterproof layer is generally 2mm-4mm, so that a good waterproof effect can be ensured.

In one embodiment, the thickness of the rigid polyurethane foam heat-insulating and water-proof layer 30 is 1.5mm-2.5 mm. The hard foam polyurethane heat-preservation waterproof layer 30 with the thickness can realize better heat-preservation effect by matching with the fiber concrete base layer 10.
The polymer mortar layer 40 is formed of polymer mortar, which is formed by stirring cement, aggregate, and an organic polymer that can be dispersed in water. The polymer may be a homopolymer obtained by polymerizing one monomer or a copolymer obtained by polymerizing two or more monomers. The polymer must form a film under ambient conditions to coat the cement particles and to form a strong bond between the cement body and the aggregate. The polymer network must have the ability to resist microcracking and crack propagation. For example, the polymer may be acrylate, polyvinyl alcohol or styrene-acrylate, and suitable polymers may be selected according to design requirements.
In one embodiment, the polymer mortar layer 40 has a thickness of 4mm to 6 mm. The polymer mortar layer 40 of this thickness cooperates with fibre concrete basic unit 10, polyurea waterproof layer 20 and hard bubble polyurethane heat preservation waterproof layer 30, and the holistic waterproof of waterproof construction that obtains, the heat preservation effect is better, and polymer mortar layer 40 thickness itself is not big moreover, can reduce cost.
In one embodiment, the waterproof structure 100 of the building is a curved surface. After the curved surface shape is made, the curved surface shape can be better matched with the shape of a special-shaped roof. For example, the roof is also curved.
In one embodiment, the roof is required to be hyperboloid shaped, and the waterproof structure 100 of the building is hyperboloid shaped as a whole.
In one embodiment, the overall length of the waterproof structure 100 is greater than 90m and the width is greater than 10 m. The size of a general roof drainage structure is small, and if the size requirement is overlarge and the requirement is abnormal, the structure in the waterproof structure can be changed, so that the waterproof effect is influenced. The size of the building waterproof structure 100 can be larger than 90m in length and larger than 10m in width, and the influence on the internal structure of the building waterproof structure is small.
The utility model also provides a building roof, including the roofing body, still include foretell building waterproof construction 100, foretell building waterproof construction's shape adaptation in the shape of roofing body, for example when the roofing body is shapes such as curved surface, dysmorphism, waterproof construction's shape also need be along with changing.
The roof body is made of concrete, and can be matched with the building waterproof structure 100 to firmly install the building waterproof structure 100 on the roof body. The roof body can be in the shape of a curved surface, a hyperboloid special shape and the like. For example, the roof body has a hyperboloid shape, and can be combined with the waterproof structure 100 of the above structure.
