Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figs. 1-3, it is a preferred embodiment of the application, a kind of heat preservation and insulation safe breeding house top structure, including shed roof, the shed roof is externally provided with multiple composite protective layers, the shed roof includes plastic-coated arch rod or stainless steel arch rod 1, the lower end of plastic-coated arch rod or stainless steel arch rod 1 is fixed by vertical column and horizontal pull rod, the lower side of plastic-coated arch rod or stainless steel arch rod 1 is also provided with steel wire rope 2 and ground anchor 3, the steel wire rope 2 is connected with plastic-coated arch rod or stainless steel arch rod 1 and ground anchor 3 by crossing, forms the arched force skeleton, the multiple composite protective layers include drip-free membrane 6, tin-foil paper flame-retardant glass fiber cotton 7, black and white film 9 and black felt layer 10 in turn from inside to outside, the surface of black felt layer 10 is sprayed with cement paste layer 11 mixed with glue.

[0019] Specifically, the plastic-coated arch rod or stainless steel arch rod 1 surface and the corresponding place of drip-free membrane 6 and black and white film 9 are provided with a clamping groove 5, and the drip-free membrane 6 and black and white film 9 are installed on the clamping groove 5 by means of a clamping spring 4; it realizes quick installation and disassembly, and is convenient for later maintenance.

[0020] Wherein, the tin-foil paper flame-retardant glass fiber cotton 7 and black felt layer 10 are provided with a film pressing belt 8 above, and several film pressing belts 8 are arranged at the jointing and sewing position, to ensure that the structure is tightly fitted.

[0021] Wherein, the tin-foil paper flame-retardant glass fiber cotton 7 is an upper and lower partition composite layer structure, the upper layer is a high-density tin-foil flame-retardant layer, and the lower layer is a low-density thermal insulation layer, and the two layers are connected by puncture hot melting points; so that the thermal insulation layer has self-rebound ability after being compressed, the structure is stable and does not collapse, and the long-term thermal insulation performance is stable.

[0022] In order to reduce thermal conductivity and reduce roof temperature fluctuation, hollow ceramic microbeads or expanded perlite micro powder are mixed in the cement paste layer 11 mixed with glue to form a light thermal insulation layer.

[0023] It can be understood that the shed roof is provided with a shed eave 12 on both sides, the surface of the shed eave 12 is also provided with a multiple composite protective layer 100, the surface of the multiple composite protective layer 100 is sprayed with a cement paste layer 11 mixed with glue, and the outwardly extending shed eave 12 can avoid direct rainwater scouring of the protective film jointing position of the shed roof, and can guide the rainwater along the eave surface to the outside of the shed to avoid water accumulation.

[0024] Wherein, the low-density thermal insulation layer is provided with a plurality of air channels near the side of the drip-free membrane 6, and a plurality of air channels are provided with air-permeable micropores to form a flexible pressure regulating cavity, which can buffer the air pressure difference when the temperature changes sharply, avoid local bulging or sinking of the drip-free membrane 6, and enhance the overall stability.

[0025] In this embodiment, the plastic-coated or stainless steel arch rods are fixed by columns and horizontal pull rods, and the two ends of the arch rods are crossed and pulled by steel ropes and fixed on ground anchors to form a stable arch-shaped stress framework, and the ground anchors are pre-fixed in the foundation pit by cement to enhance the overall wind and snow resistance;

[0026] The outer surface of the arch rod is first laid with a drip-free film 6, which has waterproof and condensation prevention functions, can avoid the formation of water droplets inside the roof due to temperature difference, prevents water pollution at the top of the henhouse, and is laid with a tin-foil paper fire-retardant glass wool 7 on the drip-free film 6. The glass wool layer contains a reflective aluminum foil layer, which can effectively reflect solar radiation heat. At the same time, the glass fiber material has good heat preservation and insulation performance and has fire-retardant properties. The glass wool is fixed on the arch rod by a film pressing belt 8 to ensure that the glass wool is tightly attached. A black and white film 9 is laid on the glass wool, with the white side facing outward to reflect sunlight and reduce the temperature rise in the shed; the black side faces inward to enhance the shading effect, which helps to control the lighting environment in the henhouse. The drip-free film 6 and the black and white film 9 are fixed in the clamping grooves 5 on both sides of the arch rod by the clamping springs 4 to realize quick installation and disassembly, which is convenient for later maintenance. A black felt layer 10 is laid outside the black and white film 9. The felt layer has wear-resistant, ultraviolet aging-resistant and corrosion-resistant functions, and can also serve as a waterproof protective layer to absorb and disperse external impacts. The joints between the felt layers are fixed by the film pressing belts 8. Finally, the surface of the felt layer is uniformly sprayed with a layer of cement slurry 11 mixed with glue. This layer can not only enhance the wind-resistant and impact-resistant capacity of the overall structure, but also form a solid outer shell to effectively prevent damage caused by animal pecking, fire baking and the like. The sprayed cement slurry layer 11 extends to cover part of the eaves 12, forming a continuous protective layer. In the long-term use process, when obvious cracks are observed in the cement sprayed layer on the roof, the mixed glue cement slurry layer 11 can be directly sprayed again to cover the old layer, thereby realizing structure reinforcement and sealing repair and prolonging the service life. The entire roof does not need to be replaced on a large scale, and low-cost maintenance can be realized.
