Description

Technical Field

[0001] The present application relates to the technical field of roof leakage prevention, and specifically to a roof leakage prevention structure. Background Art

[0002] Roof waterproofing has always been a very important project in construction. Due to reasons such as design, construction or usage principles, roof leakage is relatively common, and roof leakage affects people's living. Roof waterproofing projects generally include roof membrane waterproofing, roof coating waterproofing, roof rigid waterproofing, tile roof waterproofing, and roof joint sealing waterproofing.

[0003] The corners of houses and the joints between walls are prone to cracking. The existing waterproof structure is prone to water infiltration at the joints of wall gaps. In the long run, it will cause roof leakage. The Chinese patent (Announcement No.: CN220414692U) discloses a roof anti-leakage structure that can effectively reduce the cracking phenomenon at the joints between walls, thereby reducing roof leakage. Because roof drainage will produce drainage pipes extending from the roof, it is necessary to open drainage holes on the roof and heat-proof materials so that the drainage pipes can drain water. In addition, due to the small gaps between the pipes and the holes in the roof and the waterproof structure, when the roof is drained through the drainage pipes, the joints between the pipes, the roof and the waterproof materials often become the main leakage locations. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a roof anti-leakage structure with advantages such as being less prone to leakage, thereby solving the problem of easy leakage.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a roof anti-leakage structure, comprising a roof body, a waterproof structure for reducing cracking at the joint of the roof body fixed to the top of the inner side of the roof body, a drainage pipe fixed inside the roof body, and an anti-leakage drainage assembly provided at the top of the waterproof structure;

[0006] The anti-leakage drainage assembly includes a drainage ditch, an insert block, a stop block fixedly installed on the top of the insert block, and a sealing structure fixedly installed on the outer surface of the stop block for enhancing the sealing performance of the stop block.

[0007] The above technical solution can prevent water from accumulating at the joints of the roof main body wall gaps, further improve the anti-leakage effect of the joints of the roof cavity gaps, and seal the joint ends of the drainage pipe and the waterproof structure to reduce leakage at the joint ends.

[0008] Furthermore, a through hole is opened at the bottom end of the inner side of the drainage ditch, and a connecting hole is opened on the left side of the waterproof structure, and the through hole is connected to the connecting hole.

[0009] By adopting the above technical solution, the drain pipe can be fixed in the waterproof structure so that the waterproof structure can cover the junction between the drain pipe and the roof body, making it difficult for the drain pipe and the roof body to leak.

[0010] Furthermore, the drainage ditch is opened at the top of the waterproof structure, and the drainage pipe is L-shaped.

[0011] By adopting the above technical solution, water can be accumulated in the drainage ditch, avoiding water from abutting against the joints between the main roof and the wall.

[0012] Furthermore, the insert block and the stop block are both ring-shaped, and the diameter of the stop block is larger than the distance between the drain pipe and the insert block.

[0013] The above technical solution facilitates the fixing of the stopper to the outside of the drain pipe.

[0014] Furthermore, the diameter of the insert block is smaller than the diameter of the drain pipe, and the insert block is fixed to the inner wall of the drain pipe.

[0015] By adopting the above technical solution, the stopper can be tightly fixed to the drain pipe.

[0016] Furthermore, the sealing structure includes a waterproof layer, a waterproof coating fixedly installed on the outer surface of the waterproof layer, an anti-corrosion layer fixedly installed on the outer surface of the waterproof coating, and a wear-resistant layer fixedly installed on the outer surface of the anti-corrosion layer.

[0017] By adopting the above technical solution, the sealing performance of the stopper to the joint can be enhanced, and the phenomenon of the stopper being eroded and damaged by water corrosion can be reduced.

[0018] Furthermore, the waterproof layer is glass fiber, and the waterproof coating is a polymer waterproof coating.

[0019] The above technical solution is adopted to enhance the sealing and waterproof properties of the block.

[0020] Furthermore, the anti-corrosion layer is a perchlorethylene coating, and the wear-resistant layer is a polyarylate coating.

[0021] By adopting the above technical solution, the phenomenon of the block being corroded and damaged by water corrosion is reduced.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The roof anti-leakage structure, by being provided with an anti-leakage drainage component, can prevent water from accumulating at the joints of the gaps in the roof main body wall, further improve the anti-leakage effect at the joints of the gaps in the roof cavity, and can seal and block the joint ends of the drainage pipe and the waterproof structure, reducing leakage at the joint ends and making it less susceptible to water corrosion damage.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] See also Figure 1-2 In this embodiment, a roof anti-leakage structure includes a roof main body 1. A waterproof structure 2 for reducing cracks at the joint of the roof main body 1 is fixed to the top of the inner side of the roof main body 1. A drainage pipe 3 is fixed inside the roof main body 1, and a fixing hole is opened on the right side of the roof main body 1. The drainage pipe 3 is fixed in the fixing hole. An anti-leakage drainage component 4 is provided at the top of the waterproof structure 2.

[0030] See also Figure 2-3 The anti-leakage drainage assembly 4 in this embodiment includes a drainage ditch 41, an insert 42, a block 43 fixedly installed on the top of the insert 42, and a sealing structure fixedly installed on the outer surface of the block 43 for enhancing the sealing performance of the block 43.

[0031] Among them, a through hole is opened at the bottom end of the inner side of the drainage ditch 41, and a connecting hole is opened on the left side of the waterproof structure 2. The through hole is connected with the connecting hole, so that the through hole and the connecting hole are combined into an L-shaped hole, so that the drainage pipe 3 can be fixed in the waterproof structure 2 through the through hole and the connecting hole, and the drainage pipe 3 can be fixed on the inner side of the drainage ditch 41.

[0032] In addition, the drainage ditch 41 is opened at the top of the waterproof structure 2, and the drainage pipe 3 is L-shaped, so that water can flow into the drainage ditch 41. The water in the drainage ditch 41 can flow into the drainage pipe 3, which can prevent water from accumulating at the wall gap connection of the roof body 1, and can further improve the anti-leakage effect of the roof cavity gap connection.

[0033] In addition, the plug 42 and the block 43 are both ring-shaped, and the diameter of the block 43 is larger than the diameter between the drain pipe 3 and the plug 42, so that the block 43 can be fixed on the outside of the drain pipe 3, so that the block 43 can block the gap between the pipe and the roof hole and the waterproof structure 2.

[0034] Moreover, the diameter of the insert block 42 is smaller than the diameter of the drain pipe 3 , and the insert block 42 is fixed to the inner wall of the drain pipe 3 , so that the stopper 43 can be fixed to the outer side of the drain pipe 3 through the insert block 42 .

[0035] See also Figure 3 The sealing structure in this embodiment includes a waterproof layer 44, a waterproof coating 45 fixedly installed on the outer surface of the waterproof layer 44, an anti-corrosion layer 46 fixedly installed on the outer surface of the waterproof coating 45, and a wear-resistant layer 47 fixedly installed on the outer surface of the anti-corrosion layer 46.

[0036] Secondly, the waterproof layer 44 is glass fiber, and the waterproof layer 44 is fixed to the outside of the block 43. It has good sealing properties, is not easy to crack, and is not easy to deform. It can enhance the sealing properties of the block 43 against the drain pipe 3 and the waterproof structure 2. The waterproof coating 45 is a polymer waterproof coating. The polymer waterproof coating is composed of various matching caulking materials. The polymer waterproof coating and glass fiber can form an enhanced coating waterproof layer to enhance the waterproofness of the block 43.

[0037] At the same time, the anti-corrosion layer 46 is a polyvinyl chloride coating. The polyvinyl chloride anti-corrosion paint is formed by mixing polyvinyl chloride resin, pigments, fillers and additives. It is chemically inert, moisture-proof, mildew-proof and has good sealing properties. It also has good resistance to the atmosphere, moisture, salt, alkali, acids and petroleum. It has excellent outdoor weather resistance and is resistant to erosion by corrosive media such as the atmosphere, water, acids, alkalis, salts, oils and chemical gases, thereby reducing the erosion of the block 43 due to water corrosion. The wear-resistant layer 47 is a polyarylate coating. The polyarylate paint has strong adhesion, making it difficult for the surface of the block 43 to fall off, and has good water resistance, wear resistance and corrosion resistance, so as to ensure the stability of the block 43 during use and enhance its service life.

[0038] It should be noted that the waterproof structure 2 is well known to the public in the prior art, so its working principle will not be described in detail herein.

[0039] The working principle of the above embodiment is:

[0040] During use, a drainage ditch 41 is opened on the waterproof structure 2, and the drainage ditch 41 is fixed to the bottom of the inner cavity of the drainage ditch 41, so that water flows into the drainage ditch 41 by inertia, so that the water can accumulate in the drainage ditch 41 and flow into the drainage pipe 3 through the block 43, so that the drainage pipe 3 can discharge the water, thereby avoiding water accumulation at the joint of the wall gap of the roof main body 1, and further improving the anti-leakage effect of the joint of the roof cavity gap. The block 43 can block the gap at the junction of the drainage pipe 3 and the waterproof structure 2, thereby reducing the leakage at the gap at the junction end, and the waterproof layer 44 can enhance the sealing between the block 43 and the gap, and the waterproof layer 44 and the waterproof coating 45 can form an enhanced paint waterproof layer, thereby enhancing the waterproofness of the block 43. The block 43 is not easily corroded by water through the anti-corrosion layer 46 and the wear-resistant layer 47, so that the service life of the block 43 can be guaranteed.
