Description

Technical Field

[0001] The utility model relates to the field of roof structures, and particularly relates to a roof structure for preventing waterlogging and leakage. Background Art

[0002] The roof is a load-bearing and enclosing component at the top of a building, generally composed of a roof surface, a thermal insulation (heat insulation) layer and a load-bearing structure. The roof is also known as the "fifth elevation" of the building, which has a great influence on the shape and elevation image of the building. The form of the roof will directly affect the overall image of the building. The roof can be divided into a pitched roof and a flat roof according to the size of the drainage slope and the requirements of the building shape. The flat roof has a very small slope and mainly relies on drainage grooves and drain pipes for drainage. The existing flat roof structure directly opens drainage grooves on the roof surface and connects drain pipes for drainage. When the rainfall is too large, rainwater is likely to converge and rush into the drain pipe in one slope direction, which easily leads to the inability to drain rainwater in time. There is no filtering system in the drainage groove, and the accumulation of garbage and impurities carried by rainwater is likely to cause blockage of the water pipe, resulting in the inability to drain in time, and waterlogging and leakage may occur in the roof or the drainage groove; the area of the drainage groove is small and the length is long, and it is inconvenient to clean the accumulated garbage and impurities in the groove, which increases the maintenance difficulty of the drainage system. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a roof structure for preventing waterlogging and leakage, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A roof structure for preventing waterlogging and leakage, including a roof base surface. A drainage groove is opened at a position near the edge on the upper surface of the roof base surface. Angle filtering inclined plates are embedded and installed at positions near the drainage groove at the corners of the upper surface of the roof base surface. Straight filtering inclined plates are embedded and installed at positions near the drainage groove on the upper surface of the roof base surface. Angle filtering secondary grooves are embedded and installed at positions near the roof base surface on the upper surface of the angle filtering inclined plates. Straight filtering secondary grooves are embedded and installed at positions near the roof base surface on the upper surface of the straight filtering inclined plates.

[0006] Preferably, a roof wall is fixedly installed at the edge position on the upper surface of the roof base surface, and a drain pipe is fixedly installed on the lower surface of the roof base surface.

[0007] Preferably, a drainage inclined surface is opened inside the drainage groove.

[0008] Preferably, a main filtering groove is opened at a position near the roof base surface on the upper surface of the angle filtering inclined plate. Coarse filtering holes are opened on the upper surfaces of the angle filtering inclined plate and the main filtering groove. Rubber magnetic strips are fixedly installed at the two side edge positions on the lower surface of the angle filtering inclined plate.

[0009] Preferably, a main filtration groove is formed on the upper surface of the straight filtration inclined plate near the position of the roof base surface. Coarse filtration holes are formed on the upper surfaces of the straight filtration inclined plate and the main filtration groove.

[0011] Preferably, the straight filtration auxiliary groove is embedded and installed with the straight filtration inclined plate through the main filtration groove. Fine filtration holes are formed on the inner side surfaces of both sides of the straight filtration auxiliary groove near the upper edge position.

[0012] Compared with the prior art, the utility model has the following beneficial effects: The coarse filtration holes and the fine filtration holes filter and intercept the garbage and impurities carried by the rainwater flow. The drainage inclined surface is matched to carry out two-side diversion on the rainwater flow flowing into the drainage groove, avoiding the convergence of the rainwater volume to the same drainage outlet when the rainwater volume is too large, reducing the drainage pressure, improving the drainage efficiency, and avoiding the water accumulation and leakage in the roof or the drainage groove; The corner filtration auxiliary groove, the straight filtration auxiliary groove, the corner filtration inclined plate and the straight filtration inclined plate are all detachable, which is convenient for cleaning the filtered garbage and impurities, reducing the maintenance difficulty of the drainage system, and increasing the maintenance efficiency of the drainage system.

Detailed implementation manners

[0019] To make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0020] As Figures 1-5 shown, a roof structure for preventing waterlogging and leakage includes a roof base surface 1. A drainage groove 2 is formed at a position near the edge of the upper surface of the roof base surface 1. A corner filtering inclined plate 3 is embedded and installed at a position near the drainage groove 2 at the corner of the upper surface of the roof base surface 1. A straight filtering inclined plate 4 is embedded and installed at a position near the drainage groove 2 on the upper surface of the roof base surface 1. A corner filtering sub-groove 5 is embedded and installed at a position near the roof base surface 1 on the upper surface of the corner filtering inclined plate 3. A straight filtering sub-groove 6 is embedded and installed at a position near the roof base surface 1 on the upper surface of the straight filtering inclined plate 4.

[0021] A roof wall 101 is fixedly installed at the edge position of the upper surface of the roof base surface 1. A drain pipe 102 is fixedly installed on the lower surface of the roof base surface 1. There are four drain pipes 102 in total, which are evenly distributed at the corner positions of the lower surface of the roof base surface 1. The drain pipe 102 is communicated with the drainage groove 2. A drainage inclined surface 201 is formed inside the drainage groove 2. A main filtering groove 303 is formed at a position near the roof base surface 1 on the upper surface of the corner filtering inclined plate 3. Coarse filtering holes 301 are formed on the upper surfaces of the corner filtering inclined plate 3 and the main filtering groove 303. Rubber magnetic strips 302 are fixedly installed at the two side edge positions of the lower surface of the corner filtering inclined plate 3. A main filtering groove 303 is formed at a position near the roof base surface 1 on the upper surface of the straight filtering inclined plate 4. Coarse filtering holes 301 are formed on the upper surfaces of the straight filtering inclined plate 4 and the main filtering groove 303. Rubber magnetic strips 302 are fixedly installed at the two side edge positions of the lower surface of the straight filtering inclined plate 4. The different straight filtering inclined plates 4 and between the straight filtering inclined plate 4 and the corner filtering inclined plate 3 are magnetically connected through the rubber magnetic strips 302. The corner filtering sub-groove 5 is embedded and installed with the corner filtering inclined plate 3 through the main filtering groove 303. Fine filtering holes 501 are formed at positions near the upper edge on the two inner side surfaces of the corner filtering sub-groove 5. The straight filtering sub-groove 6 is embedded and installed with the straight filtering inclined plate 4 through the main filtering groove 303. Fine filtering holes 501 are formed at positions near the upper edge on the two inner side surfaces of the straight filtering sub-groove 6.

[0022] It should be noted that the present utility model is a roof structure for preventing waterlogging and leakage. During use, rainwater flows from the roof base surface 1 into the straight filtering auxiliary groove 6 and the corner filtering auxiliary groove 5. When the rainwater accumulated inside the straight filtering auxiliary groove 6 and the corner filtering auxiliary groove 5 reaches the position of the fine filtering holes 501, the rainwater flows into the drainage groove 2 after being filtered by the fine filtering holes 501 and the coarse filtering holes 301 inside the main filtering groove 303. The drainage inclined plane 201 diverts the rainwater and then discharges it through the drain pipe 102. When some of the fine filtering holes 501 are blocked, the connected corner filtering auxiliary groove 5 and the straight filtering auxiliary groove 6 divert the rainwater flow. When the rainwater flow overflows the main filtering groove 303, the coarse filtering holes 301 on the inclined surfaces of the corner filtering inclined plate 3 and the straight filtering inclined plate 4 play an auxiliary drainage role. When cleaning the residues intercepted by the filtration, remove the corner filtering auxiliary groove 5 or the straight filtering auxiliary groove 6 for cleaning. The corner filtering inclined plate 3 and the straight filtering inclined plate 4 are installed and separated through the rubber magnetic strip 302, and are selectively disassembled and cleaned according to the residue situation.
