Description

Technical Field

[0001] The utility model relates to the technical field of roof drainage, in particular to a detachable combined drainage outlet. Background Art

[0002] After the roof construction is completed in the building construction project, the insulation layer and the waterproof layer need to be laid. When carrying out the above-mentioned layer construction, short-term thunderstorm weather may occur, causing water accumulation in the roof insulation layer. Although emergency drainage treatment is carried out, it is inevitable that there will be incomplete treatment. This phenomenon is particularly serious during large-scale roof insulation and waterproofing construction in rainy areas. After the insulation layer and the waterproof layer are covered, some of the accumulated water retained in the insulation layer will gradually leak to the lower part of the roof, causing the roof in the room to continue to drip or be damp, which is extremely difficult to deal with.

[0003] At the same time, the existing roof drains are all single-layer drains. To ensure that the waterproof and thermal insulation quality of passive house roofs meets the quality requirements, it is necessary to have a good sunny day to meet the construction conditions, especially in the rainy season in the south, which will not only affect the construction period, but also the quality cannot be well guaranteed. Therefore, a detachable combined drain is urgently needed to solve the above problems. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a detachable combined drain outlet.

[0010] As a further solution of the utility model: a fixing screw is provided on the top of the first drain pipe, and the first drain pipe is fixedly connected to the top of the second installation groove through the fixing screw.

[0011] As a further solution of the utility model: the top outer wall of the second drain pipe is fixedly connected with a ring plate, and the number of the ring plates is two groups. The two groups of ring plates and the top of the second drain pipe form a slideway, and a fixed ball is slidably connected in the slideway. The top outer wall of the fixed ball is fixedly connected with a connecting column, and the end of the connecting column away from the fixing ball is fixedly connected to the bottom outer wall of the leaking cover.

[0025] See also Figure 1 to Figure 5 In the embodiment of the utility model, the detachable combined drain outlet includes a roofing base 5, a waterproof layer 4 is arranged on the top of the roofing base 5, a thermal insulation layer 3 is arranged on the top of the waterproof layer 4, a second installation groove 15 is opened in the waterproof layer 4 and the roofing base 5, and a first drain pipe 8 is arranged inside the second installation groove 15;

[0026] A second drain pipe 9 is inserted into the first drain pipe 8, a first installation groove 10 is provided inside the insulation layer 3, the second drain pipe 9 is installed inside the first installation groove 10, a water leakage cover 1 is provided on the top of the second drain pipe 9, and water leakage grooves 2 distributed at equal distances are provided on the circumferential outer wall of the water leakage cover 1.

[0027] Preferably, a fixing plate 17 is fixedly connected to the circumferential inner wall of the first drain pipe 8 , and the cross section of the fixing plate 17 is annular. One end of the second drain pipe 9 passes through the middle of the fixing plate 17 .

[0028] Preferably, the top outer wall of the fixed plate 17 is rotatably connected to a rotating shaft 20, and the circumferential outer wall of the rotating shaft 20 is fixedly connected to a limiting plate 19. The number of the limiting plates 19 is four groups, and the four groups of limiting plates 19 are paired to form a limiting cavity. A spring 18 is welded to the outer wall of one side of the limiting plate 19, and one end of the spring 18 away from the limiting plate 19 is fixedly connected to the circumferential inner wall of the first drain pipe 8. The circumferential outer wall of the second drain pipe 9 is fixedly connected to a clamping plate 16. During the installation of the second drain pipe 9 located on the upper part of the first drain pipe 8, it is only necessary to rotate the second drain pipe 9 to drive the clamping plate 16 to rotate. The clamping plate 16 rotates to the inside of the limiting cavity, so that it can be firmly connected to the first drain pipe 8, thereby ensuring the stability of the entire combined drain outlet during the drainage process.

[0029] Preferably, a fixing screw 7 is provided on the top of the first drain pipe 8, and the first drain pipe 8 is fixedly connected to the top of the second installation groove 15 by the fixing screw 7, thereby ensuring the stability of the first drain pipe 8 after installation.

[0030] Preferably, a ring plate 12 is fixedly connected to the top outer wall of the second drain pipe 9, and the number of the ring plates 12 is two groups. The two groups of ring plates 12 and the top of the second drain pipe 9 form a slideway, and a fixed ball 14 is slidably connected in the slideway. A connecting column 11 is fixedly connected to the top outer wall of the fixed ball 14, and one end of the connecting column 11 away from the fixed ball 14 is fixedly connected to the bottom outer wall of the leaking cover 1, which ensures that the leaking cover 1 can rotate under the influence of water flow at the top of the second drain pipe 9, thereby avoiding the situation where the leakage groove 2 on one side of the traditional fixed leaking cover 1 is blocked by leaves, etc., resulting in the inability to drain water.

[0031] Preferably, the circumferential outer walls of the two sets of ring plates 12 are fixedly connected with elastic plates 13, and the elastic plates 13 are located above the fixing balls 14 to prevent the fixing balls 14 from detaching from the slide, so that the leaking cover 1 installed in the slide can be effectively fixed. When people need to disassemble the leaking cover 1, they only need to pull the leaking cover 1 upward to deform the elastic plates 13, thereby realizing the separation of the leaking cover 1 and the second drain pipe 9.

[0032] Preferably, a filter screen 6 is fixedly connected to the inner wall of the bottom of the leaking cover 1. The cross-section of the filter screen 6 is peak-shaped, which can achieve a good filtering effect and prevent roof impurities from flowing into the pipe and causing blockage. At the same time, the cross-section of the filter screen 6 is peak-shaped. When garbage and impurities are accumulated on the lower layer of the filter screen 6, the upper layer can still continue to drain water.

[0033] Working principle: During the process of laying the roof waterproof layer 4, the staff can first install the first drain pipe 8. The first drain pipe 8 can be used as a temporary drain outlet when the roof insulation layer 3 is not completed, so that there will be no long-term accumulation of water on the structural layer of the entire roof, and the rainwater on the waterproof layer 4 can be discharged in time. When part of the insulation and waterproofing work is completed, the rainwater can also be discharged. After the entire insulation and waterproofing work of the roof is completed, the staff will insert the second drain pipe 9 into the first drain pipe 8, so that a combined drainage structure can be effectively formed. The roof rainwater flows into the first drain pipe 8 through the second drain pipe 9 and is then discharged, which effectively solves the impact of rainy weather on the quality of the insulation and waterproofing project during construction, can effectively control the construction period, and meet the needs of roof drainage and waterproofing. At the same time, during the installation of the second drain pipe 9 located on the upper part of the first drain pipe 8, it is only necessary to rotate the second drain pipe 9 to achieve a tight connection between it and the first drain pipe 8, thereby ensuring the stability of the entire combined drain outlet during the drainage process.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
