Description

Technical Field

[0001] The present application relates to the technical field of roofing, and in particular to a prefabricated layered roofing structure. Background Art

[0002] Roofing refers to the outer surface of the top of a building, usually the roof part of a building, which is used to protect the interior of the building from the elements, such as rain, wind, snow, etc. In building design and construction, the roof is an important part, and its structure, materials, waterproofing, insulation and other requirements need to be considered to ensure the safety and service life of the building.

[0003] Concrete structures are often used in roofs. Currently, integral concrete structures are often used in roofs. However, concrete tends to shrink, cool, and expand due to changes in temperature and humidity, thereby causing cracks, resulting in a high roof leakage rate. Utility Model Content

[0004] In order to reduce the leakage rate of the roof, the present application provides a prefabricated layered roof structure.

[0005] The present application provides a prefabricated layered roof structure using the following technical solutions:

[0006] A prefabricated roof layered structure, comprising:

[0007] Cement slurry layer, two cement slurry layers are provided, and the two cement slurry layers are arranged opposite to each other;

[0008] A waterproof layer, which is arranged between two cement slurry layers;

[0009] The concrete layer is arranged between the two cement slurry layers. The concrete layer comprises a concrete slab, and a plurality of concrete slabs are arranged.

[0010] By adopting the above technical solution, concrete is prefabricated in blocks rather than as an integral structure, thereby providing a reserve for the shrinkage, cooling and expansion of the concrete, thereby reducing the stress of the shrinkage, cooling and expansion of the concrete, thereby reducing cracks in the roof and achieving the effect of reducing the roof leakage rate.

[0011] Optionally, gaps are left between adjacent concrete slabs;

[0012] The concrete layer further comprises air-permeable blocks, which are arranged in the gaps between adjacent concrete slabs.

[0013] By adopting the above technical solution, there are gaps between the concrete slabs, and the air permeability of the roof can be improved by the air permeable blocks, so that the roof exhaust duct can be replaced, thereby improving the flatness of the roof.

[0014] Optionally, the concrete slabs are arranged in an array;

[0015] The four corners of the concrete slab are all provided with mounting components, and the mounting components include spacer blocks. Two spacer blocks are provided, and the two spacer blocks are respectively fixed to the two side surfaces of the concrete slab.

[0016] By adopting the above technical solution, the thickness of the two spacer blocks is equal to the gap width between two adjacent concrete slabs, thereby ensuring that the width of each gap is consistent.

[0017] Optionally, the installation assembly also includes a magnetic block, a groove is provided on the side of the spacer block away from the concrete slab fixed to itself, the magnetic block is fixed in the groove, and the two magnetic blocks in two aligned spacer blocks attract each other.

[0018] By adopting the above technical solution, two aligned spacer blocks are fixed to each other through two mutually attractive magnetic blocks, thereby fixing two adjacent concrete slabs to each other. The installation method is simple and the installation efficiency of the concrete slabs is improved.

[0019] Optionally, a lifting ring is connected to one end of the concrete slab, and the lifting ring includes a hanging part and a connecting part. The hanging part is arc-shaped, and two connecting parts are provided. The two connecting parts are rotatably connected to the two ends of the hanging part respectively, and the side wall of the concrete slab is provided with a mounting hole threadedly connected to the connecting part.

[0020] By adopting the above technical solution, the concrete slab can be hoisted through the lifting ring, so that the workers can transfer the concrete slab to the roof easily. After the hoisting is completed, the workers can remove the lifting ring by rotating the connecting part, so as not to hinder the splicing and installation of the concrete slab. The disassembly and assembly method is simple, which improves the disassembly and assembly efficiency of the lifting ring.

[0021] Optionally, the waterproof layer includes a rigid waterproof layer and a flexible waterproof layer, and the concrete layer is arranged between the rigid waterproof layer and the flexible waterproof layer.

[0022] By adopting the above technical solution, the anti-seepage performance is enhanced in both rigid waterproofing and flexible waterproofing, thereby further achieving the effect of reducing the roof leakage rate.

[0023] Optionally, the two cement slurry layers are provided with insulation boards, and a plurality of insulation boards are provided and arranged in an array.

[0024] By adopting the above technical solution, the heat exchange between the inside of the house and the outside is reduced through the insulation board, thereby improving the thermal insulation effect of the roof.

[0025] Optionally, the gap between two adjacent insulation boards is filled with a filling block.

[0026] By adopting the above technical solution, the sealing effect between adjacent insulation boards is improved by using the seam filling blocks, thereby improving the thermal insulation effect of the roof.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Concrete is prefabricated in blocks to reduce the stress of concrete shrinkage, cooling and expansion, thereby reducing cracks in the roof. At the same time, both rigid waterproofing and flexible waterproofing enhance the anti-seepage performance and reduce the leakage rate of the roof.

[0029] 2. The concrete slab is hoisted to the roof through the lifting ring to improve the transportation efficiency; the thickness of the two spacer blocks is the gap width between the two adjacent concrete slabs, and the aligned spacer blocks are fixed by the magnetic suction block, so that the two adjacent concrete slabs are assembled together to improve the assembly efficiency. Through the above structure, the laying efficiency of the concrete layer is improved. BRIEF DESCRIPTION OF THE DRAWINGS
