Description

Technical Field

[0001] The utility model relates to the field of roof water collection and drainage, in particular to a concealed overflow outlet structure. Background Art

[0002] The drainage of roof rainwater, the setting of overflow facilities and the drainage capacity must ensure that they do not affect the roof structure, wall and personnel safety. In addition, the roof rainwater drainage system should ensure that the rainwater of the design return period can be discharged in time, and when the rainwater condition exceeds the design return period, the overflow facilities must still operate safely and reliably. When determining the design return period of the roof rainwater drainage system, it should be determined based on the importance of the building, the requirements of the system and the severity of property losses or building damages that may be caused by flooding. Combining the overflow port with the rainwater pipe can meet the 50-year return period requirement.

[0003] In architectural design, the water level must be controlled within the design range. Overflows are devices used to prevent the liquid level in a container from being too high. Overflows are usually reserved on terraces and roofs. If the water level exceeds the design height, the overflows will function to drain excess water to prevent water accumulation. Traditional overflows are directly exposed to the outside, which can easily accumulate debris and cause overflow drainage blockage; and are often equipped with exposed water grates, which not only affects the overall appearance of the house, but is also susceptible to external corrosion, thus shortening its service life.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] As described in the background technology, the traditional overflow outlet is directly an open-top structure or a side open structure flush with the roof 2, which is easy to accumulate debris inside and cause blockage, affecting the overflow drainage efficiency during subsequent operation. Based on this, this embodiment provides a hidden overflow outlet structure, by setting an overflow cavity 7 in the base 10, and making the overflow outlet 4 on one side of the overflow cavity 7 and the top surface of the building roof 2 arranged vertically with a height difference, in the non-overflow state, external water is prevented from entering the overflow cavity 7, thereby avoiding the problem of debris entering the hidden overflow outlet structure to cause blockage, which can effectively solve the problem of easy blockage of the overflow outlet in the prior art. At the same time, the overflow outlet is a rectangular through hole, and there is a vertical height difference between it and the building roof 2. The opening size is small and there is no need to set a water grate, thereby ensuring the aesthetics of the building.

[0023] The present embodiment is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the concealed overflow structure includes a base 10 and an overflow pipe 9. The base 10 is the main structure, and an overflow cavity 7 is formed inside. The overflow cavity 7 is connected to the overflow port 4 and the overflow hole 8. The water accumulated on the roof 2 enters the overflow cavity 7 through the overflow port 4, and the water in the overflow cavity 7 is discharged to the outside of the building through the overflow hole 8. In order to guide the water output from the overflow cavity 7, the overflow hole 8 is connected to the overflow pipe 9, and the rainwater discharged from the overflow cavity 7 is guided to the drainage pipe of the drainage system of the roof 2 or directly discharged to the ground through the overflow pipe 9.

[0025] In order to allow the water accumulated on the roof 2 to enter the overflow cavity 7 through the overflow port 4, one side of the overflow cavity 7 is connected to the outside through the overflow port 4, that is, the overflow port 4 is horizontally facing the inside of the building, and the other side of the overflow cavity 7 is provided with an overflow hole 8, that is, the overflow hole 8 faces the outside of the building. In addition, the opening of the end of the overflow port 4 away from the overflow cavity 7 is flush with the side of the base 10 to avoid the overflow port 4 from forming a convex structure and improve its aesthetics.

[0026] In this embodiment, the base 10 is made of waterproof material, and the bottom is fixed on the structural beam 1 to ensure its stability. The side of the base 10 facing the interior of the building can be used as a side limiter for the structural roof 2 board, which can not only fix the base 10, but also ensure the installation accuracy of the roof 2 board. The parapet 5 or guardrail can be fixed on the top of the base 10 to meet the protection requirements of the edge of the roof 2, so as to improve the stability and safety of the overall structure.

[0027] In the vertical direction, the overflow port 4 is spaced apart from the top surface of the building roof 2, so that a height difference is formed between the overflow port 4 and the building roof 2 to prevent water from entering the overflow chamber 7 in a non-overflowing state. The overflow hole 8 is located between the overflow port 4 and the bottom surface of the overflow chamber 7, so that the vertical height of the overflow hole 8 is lower than the overflow port 4, which is convenient for discharging the water in the overflow chamber 7; the overflow pipe 9 is connected to the overflow chamber 7 through the overflow hole 8.

[0028] An overflow cavity 7 is formed inside the base 10, and the top of the overflow cavity 7 is blocked to prevent rainwater and dust from entering the overflow cavity 7 in a non-overflow state, and to prevent external vertical rain from entering the overflow cavity 7 from the top. On one side of the overflow cavity 7, an overflow port 4 with a rectangular through hole is arranged, and the overflow port 4 passes through the side wall of the base 10 on one side in the horizontal direction and is connected to the overflow cavity 7. The opening of the overflow port 4 is flush with the side of the base 10, facing the inside of the building horizontally, and is spaced apart from the top surface of the building roof 2 to form a height difference to prevent unnecessary water flow from entering.

[0029] On the other side of the overflow cavity 7, an overflow hole 8 is arranged, and the overflow hole 8 is located between the overflow port 4 and the bottom surface of the overflow cavity 7. The side wall thickness of the base 10 on one side of the overflow hole 8 should be greater than that on the other side, which is used to lay the parapet 5 or guardrail, and the larger side wall thickness of the base 10 is used to ensure the strength and stability of the structure.

[0030] The overflow pipe 9 is connected to the overflow chamber 7 through the overflow hole 8. When the water level exceeds the designed height, the excess water will enter the overflow chamber 7 through the overflow port 4 and be discharged through the overflow pipe 9.

[0031] In order to ensure the waterproof performance of the structure, the side of the base 10 facing the interior of the building and the top surface thereof should be covered with a waterproof layer 3, and the overflow port 4 should penetrate the waterproof layer 3 to communicate with the outside. In this way, even if water enters the base 10, it can effectively prevent water from penetrating into the interior of the building.

[0032] In addition, for aesthetics and practicality, an outer metal plate 6 can be set between the outer sides of the building, and the overflow pipe 9 can be arranged between the base 10 and the outer metal plate 6. The outer metal plate 6 can be a filter plate, fixed to the main body of the building by rivets, etc., or fixed to the parapet 5. One end of the overflow pipe 9 is horizontally connected to the overflow hole 8, and the other end is bent and extended vertically downward, so as to guide the discharged water to a suitable drainage system.

[0033] The design of the lateral overflow port 4 reduces the accumulation of impurities caused by gravity dust and rain, ensures the cleanliness of the overflow chamber 7, and avoids clogging problems.

[0034] The overflow cavity 7 formed inside the base 10 and the lateral overflow port 4 are designed so that only the overflow port 4 is exposed from the outside, which better integrates into the overall style of the building.

[0035] The traditional exposed water grates have been eliminated, which reduces the additional structural layout, reduces the construction difficulty, and improves the aesthetics of the overall structure.

[0036] The design of the waterproof layer 3 ensures the waterproof performance of the structure and effectively prevents water from penetrating into the interior of the building.

[0037] In summary, the concealed overflow structure in this embodiment has the advantages of simple structure, strong practicality, and beautiful appearance, and is suitable for drainage needs of various building roofs 2.

[0038] The above detailed description of the specific implementation of the utility model is only used as an example, and the utility model is not limited to the specific implementation described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the utility model should be included in the scope of the utility model.
