[0002] Insulation is a common design feature of building roofs. For closed insulation layers or roll-type roofs where drying is difficult, exhaust measures are recommended. Typically, an exhaust pipe is installed on the roof to remove excess moisture. Furthermore, to prevent leakage, a waterproof layer is installed on the exposed facade of the exhaust pipe. However, in practice, prolonged exposure to the exterior of the waterproof layer rapidly ages and is susceptible to damage and failure from rainwater, leading to roof leaks. Furthermore, the exhaust pipe is easily damaged by impact, making replacement a tedious, complex, and costly process. Utility Model Content

Therefore, they cannot be understood as limitations on the embodiments of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] The utility model first provides a protective sleeve.

[0032] In one embodiment, referring to the attached Figure 1 As shown, the protective sleeve includes a protective tube segment 1, a sleeve tube segment 2 and a bent tube segment 3 which are sequentially connected from bottom to top. The sleeve tube segment 2 and the protective tube segment 1 are coaxially arranged. The inner diameter of the sleeve tube segment 2 is smaller than the inner diameter of the protective tube segment 1. The bent tube segment 3 bends and extends downward.

[0033] The protective sleeve of this embodiment includes a protective tube section 1, a sleeve tube section 2 and a bent tube section 3. The overall positioning of the protective sleeve can be achieved by nesting the sleeve tube section 2 with the top end of the exhaust pipe, so that the protective tube section 1 can be coaxially sleeved on the outside of the exhaust pipe, which has good installation convenience; the protective tube section 1 plays a good protective role on the exhaust pipe and the waterproof layer on the exhaust pipe, avoiding the problem of rapid aging of the waterproof layer due to long-term exposure to the outside, and also avoiding the problem of damage to the exhaust pipe caused by impact from foreign objects, thereby improving the service life of the exhaust pipe and the waterproof layer on the exhaust pipe. In addition, the setting of the bent tube section 3 can enable the water vapor discharged from the exhaust pipe to be discharged to the outside while isolating the exhaust pipe from rainwater erosion.

[0034] Specifically, the inner diameter of the sleeve section 2 is designed according to the size of the exhaust pipe. For example, in order to adapt to a common exhaust pipe with an outer diameter of 50 mm, the inner diameter of the sleeve section 2 can be designed to be 53 mm.

[0035] In one embodiment, referring to the attached Figure 1 As shown, the protective sleeve also includes a transition section 4 connected between the sleeve section 2 and the curved section 3. The transition section 4 is coaxially arranged with the sleeve section 2. This arrangement can prevent water vapor from accumulating in the curved section 3 and the cooling liquid from turning into water and then flowing back into the exhaust pipe.

[0036] Specifically, the inner diameters of the transition barrel section 4 and the curved barrel section 3 can be set to be consistent and designed according to the size of the exhaust pipe. For example, in order to adapt to the common exhaust pipe with an outer diameter of 50 mm, the inner diameters of the transition barrel section 4 and the curved barrel section 3 can be designed to be 50 mm.

[0037] In one embodiment, referring to the attached Figure 1 As shown, the inner diameter of the transition barrel section 4 is smaller than that of the sleeve barrel section 2. A stop barrel section 5, whose inner diameter gradually decreases from bottom to top, connects the transition barrel section 4 and the sleeve barrel section 2. This arrangement ensures that when the protective sleeve is installed and placed over the exhaust pipe, the top end of the exhaust pipe contacts the stop barrel section 5, indicating that the protective sleeve is properly installed. Furthermore, the stop barrel section 5 is configured to have a gradually decreasing inner diameter from bottom to top, ensuring a smooth contact between the top end of the exhaust pipe and the stop barrel section 5.

[0038] In one embodiment, referring to the attached Figure 1 As shown, the protective sleeve segment 1 comprises a main body 11 and a guide portion 12, arranged sequentially from bottom to top. The inner diameter of the guide portion 12 gradually decreases from bottom to top. This arrangement allows the exhaust pipe to be quickly and smoothly inserted into the sleeve segment 2 under the guidance of the guide portion 12 during the protective sleeve installation process, effectively improving the convenience of the protective sleeve installation.

[0039] Specifically, the inner diameter of the main body 11 is designed according to the size of the exhaust pipe. For example, in order to fit a common exhaust pipe with an outer diameter of 50 mm, the inner diameter of the main body 11 can be designed to be 65 mm.

[0040] In one embodiment, the guide portion 12 is connected to the sleeve section 2 by a smooth transition, which can further improve the smoothness of the exhaust pipe being inserted into the sleeve section 2 under the guidance of the guide portion 12.

[0041] In one embodiment, referring to the attached Figure 1 As shown, the outer peripheral surface of the bottom end of the protective tube section 1 is convexly provided with an annular connecting flange 13. In this way, the protective sleeve can be firmly connected to the roof through the annular connecting flange 13.

[0042] Specifically, the annular connecting flange 13 is provided with a plurality of connecting through holes arranged at intervals around the protective tube segment 1, so that the annular connecting flange 13 can be fastened to the roof by fasteners such as screws. In actual application, screws are generally used to fasten the annular connecting flange 13 to the roof. As for the selection of screw specifications, screws with a length less than the thickness of the fine stone concrete protective layer (that is, the structural layer above the roof waterproof layer) are generally selected to avoid damage to the roof waterproof layer by the screws.

[0043] In one embodiment, the protective sleeve is integrally molded from HDPE. This configuration provides the protective sleeve with advantages such as light weight, easy transportation, low manufacturing cost, low temperature resistance, acid and alkali resistance, good chemical stability, non-toxicity, odorlessness, and excellent weather resistance. It also provides a certain degree of thermal insulation, effectively preventing the exhaust pipe from expanding and contracting due to heat and cooling.

[0044] In one embodiment, the wall thickness of the protective tube segment 1, the sleeve tube segment 2, and the curved tube segment 3 is 1.2 mm to 1.8 mm. Preferably, the wall thickness of the protective tube segment 1, the sleeve tube segment 2, and the curved tube segment 3 is 1.5 mm.

[0045] For ease of understanding, the specific installation process of the protective sleeve is described below:

[0046] First, place the protective sleeve on the exhaust pipe;

[0047] Slowly move the protective sleeve downwards so that the exhaust pipe can slide along the guide portion 12 into the sleeve section 2 until the top of the exhaust pipe is blocked. Then rotate and twist the protective sleeve to tightly fit the exhaust pipe and the sleeve section 2 until the protective sleeve cannot be twisted or the protective sleeve is tightly attached to the roof.

[0048] The protective layer and the annular connecting flange 13 of the roof are fastened with screws;

[0049] Use sealant to seal the edges of the fixing screws and the junction between the protective sleeve and the roof.

[0050] The utility model also proposes a roof exhaust pipe protection structure, referring to the attached Figure 2 As shown, the roof exhaust pipe protection structure includes the above-mentioned protection sleeve, the protective sleeve section 1 is sleeved on the pipe section of the exhaust pipe extending out of the roof, and the sleeve sleeve section 2 is nested and connected with the top end of the exhaust pipe.

[0051] Obviously, the roof exhaust pipe protection structure also has the beneficial effects of the above-mentioned protection sleeve.
