Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a roof with an exhaust pipe. Background Art

[0002] After the construction of a building is completed, an exhaust pipe is usually installed on the roof to dissipate heat and ventilate the roof. Roofing engineering is an important sub-project of building construction, among which the roof pipe is an important node that affects the quality of roof construction. In the prior art, such as Figure 1 As shown, the exhaust pipe consists of a straight pipe and a curved pipe at the top, and the straight pipe portion of the exhaust pipe extends into the roof waterproofing layer.

[0003] There are two construction methods for this exhaust pipe:

[0004] First, opening holes in the insulation layer, leveling layer and protective layer → installing and fixing the exhaust pipe → waterproofing construction → subsequent structural practices; the disadvantages of this construction method are: ① When the large-surface waterproof membrane is constructed to the exhaust pipe, it is necessary to partially cut the waterproof membrane in advance, which reduces the efficiency of large-surface construction; ② A separate small piece of waterproof membrane is used to turn up the exhaust pipe root. When the small piece of waterproof membrane is wrapped around the pipe root, the construction details are cumbersome and the requirements are high, which is prone to water leakage due to improper construction.

[0005] Secondly, opening holes in the insulation layer, leveling layer and protective layer → large-surface waterproofing construction → waterproofing holes in the designed position of the exhaust pipe → installation and fixing of the exhaust pipe → waterproofing of the pipe root → subsequent construction methods; the disadvantages of this construction method are: ① The exhaust hole is fixed after the waterproofing construction is completed. The construction workers may start to waterproof the nodes when the fixing materials are not completely solidified. At the same time, the fixing may be loose, which may damage the waterproofing effect of the nodes in the later stage; ② A separate small piece of waterproof membrane is used to turn up the exhaust pipe root. When the small piece of waterproof membrane is wrapped around the pipe root, the construction details are cumbersome and the requirements are high, which may cause water leakage due to improper construction.

[0034] 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.

[0035] Example

[0036] Refer to the attached drawings of the specification, such as Figure 2-Figure 8 As shown, a roof with an exhaust pipe, the roof structure of which includes a roof structure layer 3, a roof construction layer 4 and a waterproof layer 7 arranged in sequence from top to bottom. Among them, a mounting groove 31 is arranged in the roof construction layer 4, and the mounting groove 31 is located in the middle of the roof construction layer 4. Specifically, the material of the roof construction layer 3 can be one of a mud board, a cement board or a wood chip board; the material of the roof construction layer 4 can be concrete; the material of the waterproof layer 7 can be one of asphalt paper or polyurethane. The exhaust pipe includes an upper pipe component 1 and a lower pipe component 2, and the upper pipe component 1 and the lower pipe component 2 are connected by a connector 3. The upper pipe component 1 and the lower pipe component 2 are provided with exhaust pipes that pass through from top to bottom. The lower pipe component 2 is installed in the mounting groove 31 and is arranged below the waterproof layer 7. The upper pipe component 1 is located above the waterproof layer 7 and is correspondingly arranged directly above the lower pipe component 2.

[0037] By separating the exhaust pipe into an upper pipe member 1 and a lower pipe member 2, and arranging the upper pipe member 1 and the lower pipe member 2 on the upper and lower sides of the waterproof layer 7, respectively, the waterproof layer 7 can be directly laid on the roof structure layer 4 without having to avoid the installation position of the exhaust pipe, thereby improving the efficiency of the roof drainage construction. When installing the exhaust pipe, the upper pipe member 1 is directly connected to the lower pipe member 2 through a connector, and specifically, the connector 3 can be a fixing bolt.

[0038] like Figure 3 , Figure 4 as well as Figure 8 As shown, the side wall of the lower tube component 2 is provided with a plurality of air-permeable and water-seepage holes 22. The roof further includes a protective layer 5 and a peripheral fixing layer 6. The protective layer 5 is provided on the outer side of the lower tube component 2. Specifically, the material of the protective layer 5 can be a hard plastic, such as a PVC material. The height of the protective layer is equal to the height of the air-permeable and water-seepage hole 22 at the top of the lower tube component 2, so as to avoid the material constituting the roof structure from clogging the air-permeable and water-seepage hole 22. The peripheral fixing layer 6 is located on the outer side of the protective layer 5, and the peripheral fixing layer 6 fills the installation groove 31.

[0039] like Figure 4 As shown, the peripheral fixing layer 6 includes a thermal insulation layer 61 and a leveling layer 62. The leveling layer 62 is located above the thermal insulation layer 61, and the top surface of the leveling layer 62 is attached to the bottom surface of the waterproof layer 7. The upper surface of the leveling layer 62 is a plane, so as to ensure the flatness of the waterproof layer 7 during laying. Specifically, the material of the thermal insulation layer 61 is one of the rubber powder polystyrene particle thermal insulation mortar or the glass micro bead thermal insulation mortar; the material of the leveling layer 62 is one of the gypsum or cement mortar.

[0040] like Figure 6 As shown, a first base 11 is provided at the bottom of the upper tube component 1, and a second base 21 is provided at the top of the lower tube component 2. The first base 11 includes a top plate 111 and a side wall 112 perpendicular to 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; or the bottom surface of the side wall 112 is higher than the bottom surface of the upper tube component 1. The top plate 111, the side wall 112, the outer wall of the upper tube component 1 and the waterproof layer 7 are arranged to form a hollow area to be filled 12. The area to be filled 12 is poured with weather-resistant sealing material, and the connection between the upper tube component 1 and the waterproof layer 7 is further sealed by pouring weather-resistant sealing material 8. Specifically, the weather-resistant sealing material 8 can be selected from one of polymer mortar or crack grouting material.

[0041] When pouring the weatherproof sealing material 8 into the area to be filled 12, there are two ways of pouring. First, when the bottom surface of the side wall 112 of the first base 11 is higher than the bottom surface of the upper tube component 1, it can be poured from the gap between the side wall 112 and the waterproof layer 7 by injection. Second, when the bottom surface of the side wall 112 of the first base 11 is flush with the bottom surface of the upper tube component 1, a pouring port can be opened on the top plate 111 of the first base 11, and the weatherproof sealing material 8 is poured into the area to be filled 12 through the pouring port.

[0042] Based on this, the installation steps of the roof with exhaust pipe are as follows:

[0043] The roof structure layer 4 opens an installation groove 31 → the lower tube component 2 is placed in the installation groove 31 → a protective layer 5 is arranged on the outer side of the lower tube component 2 → the installation groove 31 located outside the protective layer 5 is filled with the material of the thermal insulation layer 61 and the leveling layer 62 → the lower tube component 2 is installed and fixed → the waterproof layer 7 is laid on the leveling layer 62, and the position of the lower tube component 2 is marked on the waterproof layer 7 → the waterproof layer 7 is partially cut along the inner circle of the lower tube component 2 at the position of the lower tube component 2 → the upper component 1 is fixed by the connecting piece → the formed area 12 to be filled is filled with weather-resistant waterproof sealing material 8 → subsequent construction methods are performed.

[0044] Based on the above structure, this application has the following advantages:

[0045] 1. During the construction of the exhaust pipe, the lower pipe component 2 can be installed first. The upper opening of the lower pipe component 2 is flush with the waterproof layer 9. The large surface waterproofing can be directly laid on the lower pipe component 2 to reduce the impact on the large surface waterproofing construction efficiency;

[0046] 2. The waterproof layer 9 is arranged between the upper tube component 1 and the lower tube component 2, so as to play a role of waterproof sealing. At the same time, the upper tube component 1 and the lower tube component 2 are connected by fixing bolts, which is convenient for the installation and removal of the exhaust pipe.

[0047] 3. A hollow area to be filled 13 is provided between the upper tube component 1 and the lower tube component 2, and the area to be filled 13 can be filled with weather-resistant sealing material 8, so as to completely seal the connection between the waterproof layer 9 and the upper tube component 1 of the exhaust pipe; in addition, since the upper tube component 1 and the lower tube component 2 are detachably connected, the weather-resistant sealing material 8 can be replaced regularly.

[0048] 4. The exhaust pipe can be disassembled regularly to observe whether there is water accumulation at the bottom, so as to determine whether the waterproof layer 9 is invalid; 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 6 during subsequent secondary maintenance.

[0049] 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.
