Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a roof waterproof structure. Background Art
[0002] "Roofing" usually refers to the covering part on top of a building, that is, the surface of the roof. It is not only a component of the building, but also has functions such as waterproofing, heat preservation and thermal insulation. It is also an important part of the building's appearance. The materials and design of the roof can vary depending on the region, climate, culture and building purpose.
[0003] Among them, in the prior art, for the material part of the roof, common roofing materials include asphalt tiles, metal, slate, clay tiles, wood, etc. The design for the roof can be divided into flat roofs, sloped roofs, or a combination of flat roofs and sloped roofs. Compared with a simple flat roof, the combination of flat roofs and sloped roofs can improve the beauty of the building on the one hand, but on the other hand, the water flow on the sloped roof will quickly flow from the sloped roof to the flat roof, forming rainwater accumulation, and leakage points are prone to occur at the junction of the sloped roof and the flat roof.
[0004] Therefore, during construction, the combination of flat roofs and sloping roofs needs to pay attention to waterproofing and drainage issues. Flat roofs need to be waterproofed to prevent rainwater from penetrating; while sloping roofs need to be designed with a reasonable drainage system to ensure that rainwater can be discharged smoothly. Utility Model Content
[0005] The purpose of the utility model is to solve the above-mentioned problems in the existing technology and to propose a roof waterproof structure, which can improve the waterproof performance of the junction of the slope roof and the flat roof when a roof scheme combining the slope roof and the flat roof is adopted, and avoid rainwater accumulation at the junction; at the same time, it can also prevent the leakage water from the slope roof from flowing into the flat roof structure, causing leakage at multiple points on the roof.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is specifically as follows:
[0007] A roof waterproof structure comprises a flat roof structure, a sloping roof structure, and a water retaining structure connected at the connection between the flat roof structure and the sloping roof structure, wherein the water retaining structure comprises a transition groove, a water retaining plate arranged in the transition groove, and a drainage pipe arranged in the transition groove; the flat roof structure comprises a flat roof layer, a first waterproof layer arranged on the flat roof layer, and the first waterproof layer extends into the transition groove and adheres to the water retaining plate; the sloping roof structure comprises a sloping roof layer, a second waterproof layer arranged on the sloping roof layer, and a waterproof bottom plate is arranged in the transition groove.
[0008] Furthermore, a second coiled material layer is disposed on the second waterproof layer, and the second coiled material layer extends and fits into the transition groove.
[0009] Furthermore, a first waterproof membrane layer is provided on the flat roof layer.
[0010] Furthermore, the end of the first waterproof coiled material layer is L-shaped and is attached to the inner side of the water retaining plate and connected to the waterproof base plate.
[0011] Furthermore, a plurality of water leakage holes are arranged at intervals on the drainage pipe, and the drainage pipe is connected to the eaves.
[0012] Furthermore, an arc-shaped fixing opening is provided between the drainage pipe and the water retaining plate, and a waterproof coating is applied on the arc-shaped fixing opening.
[0013] Compared with the prior art, the advantages of the utility model are: first, the utility model adopts a transition drainage trough body set between the slope roof and the flat roof, and uses the transition trough to effectively collect and discharge the accumulated water. On the one hand, it can effectively prevent rainwater from entering the flat roof along the leakage point of the slope roof after the slope roof waterproofing fails, causing the flat roof waterproofing failure; at the same time, on the other hand, it can enhance the drainage capacity of the roof and avoid problems such as rainwater accumulation at the junction of the flat roof and the slope roof.

[0024] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0025] like Figure 1-Figure 2A roof waterproof structure includes a flat roof structure, a sloping roof structure, and a water retaining structure connected at the connection between the flat roof structure and the sloping roof structure, wherein the water retaining structure includes a transition groove, a water retaining plate 8 arranged in the transition groove, and a drainage pipe 9 arranged in the transition groove; the flat roof structure includes a flat roof layer 1, a first waterproof layer 3 arranged on the flat roof layer 1, and the first waterproof layer 3 extends into the transition groove and adheres to the water retaining plate 8; the sloping roof structure includes a sloping roof layer 2, a second waterproof layer 4 arranged on the sloping roof layer 2, and a waterproof bottom plate 7 is arranged in the transition groove.
[0026] Compared with the prior art, in the prior art, waterproof layers are respectively set on the slope roof layer 2 and the flat roof layer 1 to prevent rainwater from leaking. However, at the transition between the slope roof and the flat roof, there is a lack of a separately set waterproof layer or a transition layer to provide separate waterproof protection for the flat roof. When the slope roof waterproofing fails and leaks, the leaking water easily flows along the slope roof into the waterproof layer of the flat roof, causing multiple leaks and making it difficult to determine the leaking point. When re-waterproofing, it is necessary to renovate both the flat roof mode layer and the slope roof waterproof layer. In the present utility model, a transition water retaining structure is set at the junction of the slope roof and the flat roof. The transition structure mainly adopts a transition groove at the junction of the flat roof and the slope roof, and a water retaining plate 8 and a drainage pipe 9 are respectively set in the transition groove. The waterproof structure of the flat roof layer 1 is protected by the transition groove to prevent the slope roof layer 2 from flowing into the flat roof waterproof layer after the waterproofing fails. At the same time, the setting of transition groove avoids the problem of rainwater accumulation caused by the dark corners between the sloping roof and the flat roof.
[0027] A second coiled material layer 6 is disposed on the second waterproof layer 4, and the second coiled material layer 6 extends and fits into the transition groove.
[0028] The flat roof layer 1 is provided with a first waterproof roll material layer 5. The end of the first waterproof roll material layer 5 is L-shaped and is attached to the inner side of the water retaining plate 8 and connected to the waterproof bottom plate 7. The water retaining plate 8 is provided to protect the waterproof layer of the flat roof, and the waterproof roll material is used to strengthen the protection, thereby forming a first layer of waterproof protection structure.
[0029] The drainage pipe 9 is provided with a plurality of leakage holes at intervals, and the drainage pipe 9 is connected to the eaves. An arc-shaped fixed opening 10 is provided between the drainage pipe 9 and the water retaining plate 8, and a waterproof coating is applied at the arc-shaped fixed opening 10. The drainage pipe 9 forms a second layer of waterproof protection structure. When there are many leakage points and a lot of leakage occurs, the drainage pipe 9 collects and centrally processes the failure of the waterproofing of the slope roof, which can avoid the problem of leakage water flowing in series.
[0030] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
