[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Example

[0035] Refer to the attached drawings of the specification, such as Figure 2-Figure 8As shown, a split exhaust pipe includes an upper tube component 1, a lower tube component 2, a connector and a rain cap 4. The upper tube component 1 is connected to the lower tube component 2 by a connector. The rain cap 4 is fixedly arranged above the upper tube component 1 to block the precipitation from above the upper tube component 1. The upper tube component 1 is a hollow structure with upper and lower openings, and a first base 11 is arranged at the bottom of the upper tube component 1. The first base 11 includes a top plate 111 and a side wall 112 located at the edge of the top plate 111 and perpendicular to the top plate 111. The bottom surface of the side wall 112 is flush with the bottom surface of the upper tube component 1, or the bottom surface of the side wall 112 is higher than the bottom surface of the upper tube component 1. The lower tube component 2 is also a hollow structure with upper and lower openings, and a second base 21 is arranged on the top of the lower tube component 2. A hollow area to be filled 13 is formed between the top plate 111, the side wall 112, the outer wall of the upper tube component 1 and the second base 21 in the first base 11.

[0036] Specifically, a plurality of first threaded holes 12 are provided on the first base 11; correspondingly, a second base 21 is provided on the top of the lower pipe 2, and a plurality of second threaded holes 22 are provided on the second base 21, and the positions of the second threaded holes 22 correspond to the positions of the first threaded holes 12. The connecting member is a fixing bolt 3, which passes through the first threaded hole 12, the area to be filled 13 and the second threaded hole 22 in sequence. Fig. 9 As shown, when the split exhaust pipe is actually installed, the upper pipe component 1 and the lower pipe component 2 are respectively installed on the upper and lower sides of the waterproof layer 9, and the upper pipe component 1 and the lower pipe component 2 are detachably connected by fixing bolts 3.

[0037] like Figure 5 , Figure 7 As shown, the upper pipe 1 and the lower pipe 2 are cylindrical, and the transverse cross-section of the first base 11 and the second base 21 is circular. At this time, the plurality of first threaded holes 12 on the first base 1 and the plurality of second threaded holes 22 on the second base 2 are distributed on the first base 11 and the second base 21 circumferentially around the center of the first base 1 and the center of the second base 2, respectively.

[0038] like Figure 3 , Figure 4 As shown, the first base 11 includes a top plate 111 and a side wall 112. The side wall 112 has a circular cross-sectional shape and is disposed outside the edge of the top plate 111. The bottom surface of the side wall 112 is flush with the bottom surface of the upper tube component 1, and the top surface of the second base 21 is flush with the top surface of the lower tube component 2. At this time, a hollow area to be filled 13 is enclosed between the top plate 111, the side wall 112, the upper tube component 1 and the second base 21, as shown in FIG. Fig. 9 As shown, the area to be filled 13 can be filled with weather-resistant sealing material 8, so as to completely seal the waterproof layer 9 and the exhaust pipe.

[0039] like Figure 5As shown, a plurality of filling ports 113 are provided on the surface of the top plate 111, and the filling ports 113 are connected to the filling area 13. On the top plate 111, the positions of the filling ports 113 and the positions of the first threaded holes 12 are staggered. Fig. 9 As shown, the weather-resistant sealing material 8 is poured into the filling area 13 through the filling port 113 .

[0040] like Figure 4-Figure 7 As shown, at least one first identification block 14 is provided on one side of the upper tube component 1 extending inwardly of the tube, and at least one second identification block 23 is provided on one side of the lower tube component 2 extending inwardly of the tube. The transverse cross-sectional dimension of the first identification block 14 is equivalent to the transverse cross-sectional dimension of the second identification block 23; when the upper tube component 1 and the lower tube component 2 are installed, the circumferential positions of the first identification block 14 and the second identification block 23 correspond one to one, and each first identification block 14 is located directly above a second identification block 23, so that when looking down from above the exhaust pipe, each first identification block 14 completely blocks the second identification block 23, thereby judging that the upper tube component 1 and the lower tube component 2 are correctly docked.

[0041] like Figure 4 As shown, a first extension block 15 is provided extending outward from the bottom surface of the upper tube component 1. When the fixing bolt 3 passes through the first threaded hole 11 and the second threaded hole 21, the end of the first extension block 15 is located inside the fixing bolt 3, thereby avoiding affecting the connection between the fixing bolt 3 and the upper tube component 1 and the lower tube component 2. The first extension block 15 increases the contact area of ​​the bottom of the upper tube component 1, thereby making the upper tube component 1 more stable after installation.

[0042] Similarly, if Figure 6 As shown, a second extension block 24 extends outwardly from the bottom surface of the lower tube component 2 to increase the stability of the lower tube component 2 after installation.

[0043] like Figure 6 As shown, the inner wall of the lower tube component 2 is provided with a plurality of air-permeable and water-permeable holes 25. Fig. 9 As shown, during the subsequent construction and daily use, water may accumulate in the roof structure layer 6. The water can be drained through the deep water holes 25 and then pumped into the exhaust pipe.

[0044] like Figure 2 , Figure 8 As shown, a rain shield 4 is arranged above the upper pipe 1, and the rain shield 4 is connected to the upper pipe 1 by a plurality of connecting rods 41. The rain shield 4 is a hemispherical shell. By arranging the rain shield 4, rainwater is prevented from entering the exhaust pipe during precipitation, while the exhaust pipe can be exhausted normally.

[0045] Based on the above structure, this application has the following advantages:

[0046] 1. A to-be-filled area 13 is formed between the first base 11 at the bottom of the upper tube component 1 and the second base 21 at the top of the lower tube component 2. The to-be-filled area 13 can be filled with a weather-resistant sealing material 8, so that the connection position between the upper tube component 1 and the lower tube component 2 is completely sealed;

[0047] 2. The upper tube component 1 and the lower tube component 2 are connected by fixing bolts 3, which facilitates the installation and removal of the upper tube component 1 and the lower tube component 2, and also facilitates the regular replacement of the filling material in the to-be-filled area 13;

[0048] 3. The upper tube component 1 and the lower tube component 2 are respectively provided with a first identification block 14 and a second identification block 23, so as to facilitate the determination of whether the upper tube component 1 and the lower tube component 2 are installed at the designated position;

[0049] 4. The exhaust pipe can be disassembled regularly to observe whether there is water accumulation at the bottom, so as to judge whether the waterproofing fails; at the same time, the lower pipe component 2 is provided with a breathable and water seepage hole 25, which is convenient for draining the roof structure layer during subsequent secondary maintenance.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
