Detailed Description of the Embodiments

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be further described in detail below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are some but not all of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-5, in this embodiment, an assembled roof waterproof and insulation system is provided, which includes a plurality of fully prefabricated roof floor slabs 10 with stepped surfaces at both ends. The stepped surfaces at the head and tail ends of adjacent fully prefabricated roof floor slabs 10 form a hollow part with a larger upper part and a smaller lower part. The upper part of the hollow part is covered with a fully prefabricated roof cover plate 20, and the fully prefabricated roof cover plate 20 is flush with the top of the fully prefabricated roof floor slab 10. A gap is left between adjacent fully prefabricated roof floor slabs 10, and a PE rod 40 is arranged in the gap to seal the hollow part.

[0021] The bottom of the fully prefabricated roof floor slab 10 is a precast floor slab 101. The top of the precast floor slab 101 is connected to a precast slope layer 102. The top of the precast slope layer 102 is covered with a first waterproof coiled material 103. The top of the first waterproof coiled material 103 is connected to a first insulation layer 104. The top of the first insulation layer 104 is connected to a first waterproof layer 107. The top of the first waterproof layer 107 is covered with a second waterproof layer 108. A first bonding layer 105 is arranged on the top of the second waterproof layer 108. The top of the first bonding layer 105 is connected to a first floor tile 106.

[0022] The bottom of the fully prefabricated roof cover plate 20 is a second waterproof coiled material 201. The second waterproof coiled material 201 is connected to the first waterproof coiled material 103. A second insulation layer 202 is arranged on the top of the second waterproof coiled material 201. The top of the second insulation layer 202 is connected to a third waterproof layer 205. The top of the third waterproof layer 205 is covered with a fourth waterproof layer 206. A second bonding layer 203 is arranged on the top of the fourth waterproof layer 206. The top of the second bonding layer 203 is connected to a second floor tile 204.

[0023] Specifically, as Figure 1 shown, a grouting layer 50 is poured at the bottom of the hollow part, and a water stop strip 30 is arranged between the grouting layer 50 and the fully prefabricated roof floor slab 10.

[0024] The use of the PE rod 40 and the water stop strip 30 can improve the waterproof performance of the entire assembled roof waterproof and insulation system.

[0025] The bottom of the fully prefabricated roof floor slab 10 is a precast floor slab 101. The top of the precast floor slab 101 is connected to a precast slope layer 102. The precast slope layer 102 has a slope of 3%. The use of the slope layer can facilitate the flow of the accumulated water on the roof in the same direction, thus facilitating the waterproof measures on the roof.

[0026] Specifically, the first insulation layer 104 and the second insulation layer 202 are respectively connected to the tops of the first waterproof coiled material 103 and the second waterproof coiled material 201. Since the indoor and outdoor temperatures are affected by factors such as weather, the use of the insulation layer can play a role in heat preservation and insulation for the interior.

[0027] Specifically, the first waterproof coiled material 103 is arranged on the top of the precast slope layer 102, and the second waterproof coiled material 201 is laid loose above the reserved part of the precast slope layer 102. The first waterproof coiled material 103 and the second waterproof coiled material 201 are self-adhered and overlapped to form the bottom waterproof layer. The partial loose laying can reduce the direct contact between the waterproof coiled material and the base layer, which is applicable to various situations of the base surface. The bottom waterproof layer can further moisture-proof the roof surface and prevent the problem of indoor dampness.

[0028] The first waterproof layer 107 is arranged on the top of the first thermal insulation layer 104, and the third waterproof layer 205 is arranged on the top of the second thermal insulation layer 202. The first waterproof layer 107 and the third waterproof layer 205 form the lower waterproof layer.

[0029] The second waterproof layer 108 is arranged on the top of the first waterproof layer 107, and the fourth waterproof layer 206 is arranged on the top of the third waterproof layer 205. The second waterproof layer 108 and the fourth waterproof layer 206 are overlapped. The second waterproof layer 108 and the fourth waterproof layer 206 form the upper waterproof layer. The use of the upper waterproof layer and the lower waterproof layer can handle the excess accumulated water to a great extent, thus solving the waterproof problem of the roof.

[0030] For an assembled roof waterproof and thermal insulation system of the present utility model, when rain or snow weather comes, the indoor can be effectively waterproofed through the upper waterproof layer, the lower waterproof layer and the bottom waterproof layer. The use of the thermal insulation layer can adapt to various extreme weather conditions and thus ensure the stable indoor temperature. Since it is prefabricated parts produced in the factory, the installation efficiency can be improved and the environmental pollution can be reduced.
