Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a dual-system roof drainage system. Background Art

[0002] In recent years, the number of extreme rainstorms has increased year by year. The existing drainage system cannot promptly absorb the large-scale water accumulation on the roof caused by short-term heavy rainfall, which has an adverse impact on the durability of the roof waterproof layer and the bearing capacity of the roof structure. Due to the above reasons, there is a design gap in the design standards of today's roof drainage systems, making it difficult to ensure that the roof has sufficient drainage capacity in extremely extreme weather.

[0023] In order to more clearly illustrate the specific implementation methods of the present invention or the technical solutions in the prior art, the drawings required for use in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some implementation methods of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0027] 1-roof eaves; 2-sump; 3-siphon drainage pipeline; 4-eaves drainage pipe; 5-parapet; 6-water guide channel; 7-roof; 8-roof slope layer; 9-eaves slope layer; 10-overflow; 11-waterproof layer; 12-pipeline accommodating cavity; 13-decorative panel.

[0028] The technical solution of the present invention has the following advantages:

[0029] 1. The dual-system roof drainage system provided by the present invention includes: a siphon drainage mechanism, which removes accumulated water through the siphon principle; an independent roof rainwater drainage mechanism, including: a sump arranged on the roof eaves; the siphon drainage mechanism and the independent roof rainwater drainage mechanism drain water through independent siphon drainage pipelines and eaves drainage pipes respectively; the sump is connected to the eaves drainage pipe.

[0030] In the present invention, an independent rainwater drainage mechanism and a siphon drainage mechanism are provided on the roof. The two drainage systems work together to effectively solve the problem that the roof drainage system in the prior art cannot meet the rainfall in extreme weather conditions because the drainage capacity is unable to meet the rainfall in extremely extreme weather conditions due to the use of a single drainage system. Moreover, by setting the siphon drainage pipeline of the siphon drainage mechanism and the eaves drainage pipe of the independent rainwater drainage mechanism on the roof as two separate drainage pipelines, it is ensured that the two sets of drainage mechanisms will not affect each other, and the pressure difference between the water level of the rainwater accumulation and the drainage pipe is greater than or equal to 500 mm to produce a better siphon effect. Moreover, by setting the independent rainwater drainage mechanism on the roof, the accumulated water on the roof eaves can be effectively discharged to ensure the normal drainage of the roof.

[0031] 2. The dual-system roof drainage system provided by the present invention, the siphon drainage mechanism includes: a water guide channel arranged on the parapet; the water guide channel connects the roof eaves and the roof.

[0032] In the present invention, a water guide channel is arranged on the parapet, and the water guide channel can effectively connect the roof eaves and the roof, so that the accumulated water on the roof flows to the roof eaves and is smoothly discharged.

[0033] 3. The dual-system roof drainage system provided by the present invention, the siphon drainage mechanism also includes: a roof slope layer arranged on the side of the parapet away from the roof eaves; the roof slope layer is connected to the siphon drainage pipeline through the water guide channel.

[0034] The siphon drainage mechanism in the present invention also includes a roof slope layer, which can effectively guide the accumulated water to be discharged through the parapet wall through the siphon drainage pipeline and the overhanging eaves drainage pipe. The overhanging eaves drainage pipe can effectively drain water, thereby ensuring that the siphon drainage pipeline can achieve drainage through the siphon effect.

[0035] 4. In the dual-system roof drainage system provided by the present invention, the drainage slope of the roof slope layer is between 0.5% and 2%; and / or, the roof eaves are provided with an eaves slope layer with a drainage slope between 0.5% and 2%. Preferably, the drainage slopes of the roof slope layer and the eaves slope layer are 1%.

[0036] The slope of the slope layer of the roof drainage system in the prior art is 2%. For a slope layer with a slope of 2%, when the roof area is too large and the depth is too large, the slope layer will be too thick. For example, if it exceeds 10m, the thickness of the slope layer can be up to 200mm. A too thick slope layer will cause the structural load pressure of the roof drainage system to be greater, occupy a greater depth of planting soil, thereby affecting plant growth, the water catchment area division is too complicated, and maintenance is difficult. In order to solve the above problems, the present invention improves the drainage efficiency by setting a dual-system roof drainage system, and reduces the slope of the slope layer to effectively reduce the thickness of the slope layer.

[0037] 5. In the dual-system roof drainage system provided by the present invention, the parapet is also provided with an overflow port for ensuring that the depth of the accumulated water does not exceed the height limit of the roof. The area of ​​the overflow port corresponding to each 1,000 square meters of the roof is not less than 40,000 mm.

[0038] In the present invention, drainage redundancy is achieved by setting an overflow outlet whose opening area can meet drainage requirements, thereby ensuring that the depth of water accumulation on the roof does not exceed a limit.

[0039] 6. The dual-system roof drainage system provided by the present invention further includes: a waterproof layer, wherein the waterproof layer wraps the parapet, the roof eaves, and the roof.

[0040] By wrapping the parapet with a waterproof layer, it is ensured that when the flooding height is high, the waterproof layer can also prevent the accumulated water from damaging the parapet and the auxiliary accessories on the parapet, such as hanging boards, keels, lighting wires, etc.

[0041] 7. The dual-system roof drainage system provided by the present invention also includes: a pipe accommodating cavity, which is surrounded by the roof eaves and the decorative panel located below the roof eaves; the eaves drainage pipe and the siphon drainage pipeline are both arranged in the pipe accommodating cavity.

[0042] In the present invention, the pipe accommodating cavity surrounded by the roof eaves and decorative panels can effectively accommodate the eaves drainage pipe, siphon drainage pipe or circuit pipeline, thereby effectively protecting the eaves drainage pipe and siphon drainage pipe, and avoiding exposure of the pipeline to affect the aesthetics of the building.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Example 1

[0048] This embodiment provides a dual-system roof drainage system, such as Figure 1 As shown, it includes:

[0049] The siphon drainage mechanism drains the accumulated water by the siphon principle; the siphon drainage mechanism in this embodiment comprises: a water guide channel 6 arranged on the parapet 5, and a roof slope layer 8 arranged on the side of the parapet 5 away from the roof eaves 1; the roof slope layer 8 is connected to the siphon drainage pipeline 3 through the water guide channel 6; and the drainage slope of the roof slope layer 8 and the eaves slope layer 9 is 1%;

[0050] The independent roof rainwater drainage mechanism comprises: a water collection pit 2 arranged on the roof overhang 1, wherein the water collection pit 2 is arranged at the outer contour edge position of the roof overhang 1;

[0051] The siphon drainage mechanism and the independent rainwater drainage mechanism on the roof drain water through the independent siphon drainage pipeline 3 and the eaves drainage pipe 4 respectively; the sump 2 is connected with the eaves drainage pipe 4; in this embodiment, the siphon drainage pipeline 3 and the eaves drainage pipe 4 are both arranged on the side of the roof eaves 1 close to the parapet 5, and the siphon drainage pipeline 3 and the eaves drainage pipe 4 are arranged side by side in the vertical direction;

[0052] A waterproof layer 11, wherein the waterproof layer 11 wraps the parapet 5, the roof eaves 1, and the roof 7;

[0053] The pipeline accommodating chamber 12 is surrounded by the roof eaves 1 and a decorative panel 13 located below the roof eaves 1 ; the eaves drain pipe 4 and the siphon drain pipe 3 are both arranged in the pipeline accommodating chamber 12 .

[0054] like Figure 2 As shown, rainwater collected on one side of the roof 7 flows to the roof overhang 1 through the water guide channel 6, and part of the rainwater flows into the siphon drainage pipe 3 and is discharged through the siphon effect. The rainwater that cannot be discharged by the siphon drainage pipe 3 flows to the roof overhang 1, is stored in the sump 2 and is discharged through the overhang drainage pipe 4.

[0055] The above-mentioned independently arranged independent rainwater drainage mechanism and siphon drainage mechanism work together to effectively solve the problem that the drainage capacity of the existing roof drainage system cannot meet the rainfall in extreme weather because the roof drainage system in the prior art adopts a single system for drainage. In addition, by setting the siphon drainage pipeline 3 of the siphon drainage mechanism and the eaves drainage pipe 4 of the independent rainwater drainage mechanism on the roof as two separate drainage pipelines, it is ensured that the two sets of drainage mechanisms will not affect each other, and the pressure difference between the water level of the rainwater accumulation and the liquid level of the drainage pipe is greater than or equal to 500 mm to produce a better siphon effect.

[0056] In this embodiment, if Figure 1 As shown, the parapet 5 is also provided with an overflow port 10 for ensuring that the depth of the accumulated water does not exceed the height limit of the roof. The area of ​​the overflow port 10 corresponding to each thousand square meters of the roof 7 is not less than 40000mm. By setting the overflow port 10 with an opening area that can meet the drainage requirements, drainage redundancy is achieved to ensure that the depth of the accumulated water on the roof does not exceed the limit.

[0057] Of course, the present invention does not impose any specific limitation on the drainage slope of the roof slope layer 8 and the eaves slope layer 9. In other embodiments, the drainage slope of the roof slope layer 8 and the eaves slope layer 9 is 1.5 percent.

[0058] Of course, the present invention does not impose any specific restrictions on the location of the siphon drainage pipe 3 of the siphon drainage mechanism. In other embodiments, the siphon drainage pipe 3 is arranged on the side of the parapet 5 close to the roof 7; the eaves drainage pipe 4 is arranged on the side of the parapet 5 close to the roof eaves 1.

[0059] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
