DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0036] As Figure 1 、 Figure 2 shown, a rigid waterproof structure for a steel structure roof includes a roof purlin 1, an inner roof panel 2, a vapor barrier film 3, an insulation layer 4, a rigid waterproof layer 5, an outer roof panel 6 and a drainage assembly 7.

[0037] As Figure 1 、 Figure 2 shown, the roof purlin 1 is a C-shaped channel steel and is spaced apart at the top of the steel structure house. The inner roof panel 2 is arranged above the roof purlin 1, and the inner roof panel 2 is connected to the roof purlin 1 by self-tapping screws with waterproof rings.

[0038] As Figure 1 、 Figure 2As shown in the figure, the vapor barrier 3 is laid above the roof inner panel 2. The vapor barrier 3 is an aluminum foil modified bitumen self-adhesive waterproof membrane with a thickness of 0.3 - 0.7 mm. The insulation layer 4 is arranged above the vapor barrier 3. The insulation layer 4 includes a support lining 41 and a rock wool layer 42. The support lining 41 is arched and arranged between the vapor barrier 3 and the rigid waterproof layer 5. The rock wool layer 42 fills the inside of the support lining 41 and the gap between the vapor barrier 3 and the rigid waterproof layer 5, which can have heat preservation and heat insulation effects.

[0039] As Figure 1 , Figure 2 shown in the figure, the rigid waterproof layer 5 is arranged above the insulation layer 4. The rigid waterproof layer 5 uses portland cement as the base material and is proportioned with polymer mortar and waterproof concrete, with a thickness of not less than 50 mm. The roof outer panel 6 is arranged above the rigid waterproof layer 5, and the drainage assembly 7 is arranged above the roof outer panel 6.

[0040] Therefore, by setting the rigid waterproof layer 5 and the vapor barrier 3, double-layer waterproofing inside and outside is realized. And by replacing the existing waterproof coiled material with the rigid waterproof layer 5, the roof has a good waterproof effect, a long service life, does not need to be frequently disassembled and replaced, and at the same time, the problem of waterproofing and water seepage of the steel structure roof is solved from the root.

[0041] As Figure 1 , Figure 2 shown in the figure, the drainage assembly 7 includes a plurality of drainage plates 71 with a V-shaped cross-section. The drainage plates 71 are inclined and arranged above the roof outer panel 6, and the height decreases continuously from the center of the roof to the outside. Drainage channels 72 are arranged on the sides of the roof inner panel 2 and the roof outer panel 6, and the drainage channels 72 are located on one side of the lower position of the drainage plates 71.

[0042] Therefore, by setting the drainage plates 71 to protect the top of the roof outer panel 6, on the one hand, the direct impact of external forces is reduced, and on the other hand, the rainwater can be diverted and guided into the side drainage channels 72, and discharged through the drainage channels 72 to both ends, avoiding the rainwater from flowing out directly under the eaves, which helps the drainage of the roof top, avoids the accumulation of rainwater at the top, and extends the service life of the entire waterproof structure.

[0043] As Figure 1 , Figure 3 shown in the figure, buffer parts 8 are arranged at both ends of the drainage plates 71. The buffer parts 8 include hollow tubes 81, sliding rods 82, springs 83 and limit blocks 84. The hollow tubes 81 are vertically arranged on the roof outer panel 6, and the sliding rods 82 are vertically and slidably connected to the hollow tubes 81.

[0044] As Figure 1 , Figure 3As shown, a spring 83 is disposed within a hollow tube 81 and is located below a sliding rod 82. A limit block 84 is disposed on the lower sidewall of the sliding rod 82, and a limit groove 85 for the limit block 84 to slide is provided on the hollow tube 81.

[0045] Therefore, when the drainage board 71 is squeezed, it will drive the sliding rod 82 to squeeze the internal spring 83, causing the limit block 84 to slide inside the limit groove 85, achieving the effect of buffering external force impacts, protecting the roof outer panel 6, and preventing the roof outer panel 6 from deforming.

[0046] The specific embodiments are only explanations of the present invention and are not limitations thereof. Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
