Abstract
Description
Technical Field
[0001] This utility model relates to a waterproof structure for a stepped irregular unit roof, belonging to the field of building roof waterproofing technology. Background Technology
[0002] Traditional roof waterproofing methods can achieve good waterproofing results on flat or gently sloping continuous roofs through methods such as rolling material application, coating coverage, or overlapping metal covers. However, when there are differences in the height of the roof slabs, the joints between the slabs form vertical or near-vertical inside corners, outside corners, or stepped structures. This makes it difficult for conventional waterproofing materials to adhere tightly to the substrate, easily leading to problems such as hollow areas and curling edges. Furthermore, rainwater tends to accumulate or swirl at these height differences, increasing the impact and penetration of the water flow, further exacerbating the risk of waterproofing failure. Therefore, new solutions are needed to address this issue. Utility Model Content

Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] As attached Figure 1-2As shown, the waterproof structure of the stepped irregular unit roof of this utility model includes a unit roof body, a unit frame 1, a waterproof aluminum plate 2, a waterproof membrane 3, and a drip edge 4.
[0022] The adjacent unit roof bodies are distributed in a stepped manner. Each unit roof body includes a glass panel 5 and an aluminum alloy subframe 6. The glass panel 5 is fixed to the aluminum alloy subframe 6 by mechanical connection or structural adhesive connection. Adjacent aluminum alloy subframes 6 are installed on the same unit frame 1 to form a stable stepped structural foundation.
[0023] The waterproof aluminum plate 2 is connected and fixed to the side of the unit frame 1. Its upper and lower ends are sealed to the ends of the adjacent glass panels 5 by sealant 9 to form the first waterproof barrier. Foam rods 10 are set on the lower side of the sealant 9 to enhance the sealing effect and avoid aging problems caused by the sealant 9 directly contacting the base layer.
[0024] Furthermore, a 10mm thick heat insulation blanket 22 is installed along the entire inner side of the waterproof aluminum plate 2, which serves both waterproof and heat insulation functions.
[0025] In this embodiment, the waterproof membrane 3 is a polymer waterproof membrane. The waterproof membrane 3 is pasted on the outside of the waterproof aluminum plate 2, and the upper and lower ends of the waterproof membrane 3 are respectively connected to the adjacent glass panel 5 to form a second waterproof barrier.
[0026] The drip edge 4 is detachably connected to the outside of the waterproof aluminum plate 2. Specifically, a support member 21 is provided on the outside of the waterproof aluminum plate 2, and a groove structure 211 is formed between the support member 21 and the waterproof aluminum plate 2. The drip edge 4 is provided with a hook member 41, which has a hook connector 411. The drip edge 4 is hooked into the groove structure 211 of the waterproof aluminum plate 2 through the hook connector 411, so as to realize quick installation and disassembly. When the waterproof component ages or is damaged, it can be quickly disassembled and replaced without large-scale modification of the overall structure, thus reducing the later maintenance cost.
[0027] The upper and lower ends of the drip edge 4 are respectively sealed to the adjacent glass panel 5. Specifically, both the upper and lower ends of the drip edge 4 have a bending structure 42. The bending structure 42 at both ends of the drip edge 4 is sealed to the adjacent glass panel 5 through sealant 9. Foam rods 10 are provided on the sealant 9 to form a third waterproof barrier.
[0028] A three-layer waterproof structure is formed by waterproof aluminum plate 2, waterproof membrane 3 and drip edge 4, and each waterproof component is sealed to the glass panel 5, which greatly reduces the possibility of rainwater penetration and solves the problem of easy failure of traditional single waterproof layer structure.
[0029] Furthermore, an equal pressure cavity 7 is formed between the waterproof aluminum plate 2 and the drip edge 4, and a drainage hole 8 is provided at the bottom of the drip edge 4. The equal pressure cavity 7 between the waterproof aluminum plate 2 and the drip edge 4 can balance the air pressure and prevent rainwater from being "sucked in" due to the pressure difference between the inside and outside. At the same time, the drainage hole 8 at the bottom of the drip edge 4 can drain the water accumulated in the cavity in time, further improving the waterproof effect.
[0030] Furthermore, the top of the drip edge 4 has a drainage slope 43, which can play a role in water drainage and prevent rainwater from accumulating on the top of the drip edge 4. The top of the drip edge 4 is flush with the outer surface of the glass panel 5 to ensure the appearance.
[0031] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
