Description

Technical Field

[0001] This invention relates to the field of drainage pipe fittings technology, specifically to a multi-functional drainage outlet pipe fitting for horizontal rainwater drainage on roofs and its construction method. Background Technology

[0002] Existing waterproofing construction methods include the following two forms: The existing non-structural slope-finding waterproofing construction method is as follows: structural slab construction → double-layer waterproof membrane inverted installation → slope-finding construction → thermal insulation layer construction (including exhaust pipe installation) → mortar protective layer construction → rigid concrete surface layer construction (including exhaust pipe outlet installation). The existing structural slope-finding waterproofing construction method is as follows: structural slab construction → double-layer waterproof membrane inverted installation → thermal insulation layer construction (including exhaust pipe installation) → mortar protective layer construction → rigid concrete surface layer construction (including exhaust pipe outlet installation).

[0003] With the increasing number of construction projects, roof leakage incidents are becoming more frequent, and there are many reasons for the leakage. For example, during the construction of double-layer waterproof membrane in an inverted manner, the waterproof membrane needs to be laid several centimeters below the drain outlet. This method of laying the waterproof membrane below the drain outlet will reduce the diameter of the drain outlet, thus directly affecting the smoothness of drainage. This is especially true in humid climates such as Central Asia and subtropical regions, where rainfall is abundant and frequent. Poor drainage will cause rainwater to seep from the rigid concrete surface layer into the thermal insulation layer.

[0004] In addition, there are exhaust pipes installed inside the thermal insulation layer, and the exhaust ends of the exhaust pipes are exposed outside the roof. The exhaust ends of the exhaust pipes are prone to aging and damage, which can lead to water entering the exhaust pipes. Once water enters the exhaust pipes, it will directly seep into the thermal insulation layer.

[0005] The aforementioned conditions cause the water inside the thermal insulation layer to remain saturated for extended periods, eventually leading to leaks that are difficult to locate and compromise the insulation's effectiveness. Furthermore, the constant saturation of the insulation layer means the rigid concrete layer is perpetually submerged in this water, significantly shortening its lifespan. Additionally, the waterproofing membrane at the drainage outlets may age and crack as a result.

[0006] After the above problems occur, the construction unit will carry out waterproofing repairs. The cost of roof leakage repair is also considerable, causing serious economic losses to the construction unit. Moreover, waterproofing repairs can never solve the problem of water seepage from the insulation layer not being able to drain in time, thus causing roof leakage. The applicant's prior patent application, patent number 202211282823.9, proposed a multi-functional drain outlet fitting for vertical roof rainwater drainage. This technical solution addresses the problem of roof leakage caused by the inability to drain water from the insulation layer in a timely manner. However, this design is only applicable to vertical roof rainwater drainage and cannot meet the needs of horizontal roof rainwater drainage. For example, if the drain fitting is used in a location with a parapet wall, the issue of horizontal drainage needs to be considered. Therefore, there is an urgent need to design a multi-functional drain outlet fitting and construction method for horizontal roof rainwater drainage. Summary of the Invention

[0007] The purpose of this invention is to provide a multifunctional drainage outlet pipe fitting for horizontal rainwater drainage on roofs and a construction method therefor, in order to solve at least one of the aforementioned problems existing in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A multi-functional drainage outlet fitting for horizontal rainwater drainage on roofs includes a first component and a second component. The first component includes an open portion and a pipe connection portion, wherein the open portion and the pipe connection portion are connected. The open portion includes a vertical open portion and a horizontal extension portion, wherein the horizontal extension portion extends outward from the lower end of the vertical open portion. Waterproof membrane sealing grooves are provided around the periphery of both the vertical open portion and the horizontal extension portion. The second component includes a vertical support and a horizontal support. The vertical support is connected to the vertical opening, and the horizontal support is connected to the horizontal extension. Both the vertical support and the horizontal support are connected to the opening. The transverse support is provided with an exhaust pipe pre-installed head and a through hole. The transverse support includes a baffle extending downward at an incline from the upper end of the transverse support. The outer side of the baffle is an outer channel, and the inner side of the baffle is an inner channel. The exhaust pipe pre-installed head and the through hole are both connected to the outer channel. A channel opening is left between the outer channel and the transverse extension. The channel opening is connected to the inner channel, and the inner channel is connected to the vertical opening.

[0009] In this technical solution, since the first component and the second component are set separately, they can be installed in an adaptable manner with the existing waterproofing construction steps. After the first component is installed, the waterproof membrane is provided with sealing grooves around the vertical opening and the horizontal extension, which can be used to conveniently seal the waterproof membrane before installing the second component. The sealing grooves around the vertical opening and the horizontal extension mainly solve the problem of the membrane ends cracking after aging.

[0010] Since the opening includes a vertical opening and a horizontal extension, with the horizontal extension extending outward from the lower end of the vertical opening, the vertical support of the second component connects to the vertical opening, and the horizontal support of the second component connects to the horizontal extension. Both the vertical support and the horizontal support are connected to the opening. This design is well-suited for locations with parapet walls, meeting the requirements for horizontal drainage and achieving better horizontal drainage.

[0011] Because the transverse support has a pre-installed vent pipe and a through hole, and includes a baffle extending downwards from its upper end, with the outer side of the baffle being the outer channel and the inner side being the inner channel, vertical drainage will not affect the thermal insulation layer. Since both the pre-installed vent pipe and the through hole are connected to the outer channel, and an opening connects the outer channel to the transverse extension, and this opening connects to the inner channel, and the inner channel connects to the vertical opening, after the second component is installed, the pre-installed vent pipe is connected to the vent pipe within the thermal insulation layer. Therefore, when water enters the vent pipe, it can be discharged sequentially through the pre-installed vent pipe, the outer channel, the inner channel, the vertical opening, and the pipe connection. Simultaneously, the venting effect of the insulation layer can also be achieved by connecting it with the vent pipe inside the insulation layer, with the venting path being the same as above. Since there are through holes on the horizontal support, and these through holes are connected to the outer channel, after the second component is installed, the through holes are located inside the insulation layer. Therefore, when water seeps into the insulation layer, the water can be discharged from the through holes to the outer channel, and then discharged sequentially through the inner channel, the vertical opening, and the pipe connection. At the same time, the through holes can also achieve the venting effect of the insulation layer, with the venting path being the same as above. In addition, since there is a channel opening between the outer channel and the horizontal extension, and the channel opening is connected to the inner channel, the channel opening not only achieves the connection between the outer channel and the inner channel, but also ensures the natural air intake effect after the water that has leaked from the rigid concrete surface into the insulation layer is discharged.

[0012] In summary, this technical solution changes the traditional single function of roof drainage outlets. It goes beyond basic roof drainage, enabling drainage, ventilation, and air intake within the thermal insulation layer. It effectively removes accumulated water and moisture from the insulation layer, thus solving the problems of rainwater drainage, water accumulation in the insulation layer, ventilation, and air intake. Furthermore, it addresses the issue of water accumulation in the insulation layer caused by aging of exposed roof vent pipes. This solution solves the problem of roof leaks due to the inability to drain water from the insulation layer in existing designs. It also addresses the issue of rigid concrete being constantly soaked in water within the interlayer, leading to a significantly shortened lifespan of the rigid concrete. Additionally, it resolves the problem of aging and cracking of the waterproof membrane at the drainage outlet, while simultaneously meeting the requirements for lateral drainage, resulting in better lateral drainage performance.

[0013] Furthermore, in order to achieve a better waterproof membrane sealing effect, the waterproof membrane sealing groove on the vertical open part is connected to the waterproof membrane sealing groove on the horizontal extension part.

[0014] Furthermore, to facilitate the finishing operation of the waterproof membrane on the ground, the waterproof membrane finishing groove on the transverse extension includes a lower guide portion and an upper limit portion. The end of the waterproof membrane is located in the area between the lower guide portion and the upper limit portion, and the length of the upper limit portion is less than the length of the lower guide portion.

[0015] Furthermore, in order to ensure the structural strength of the second component and to facilitate the support and installation of the bracket or heightening component, a corner support is provided between the vertical support and the horizontal support.

[0016] Furthermore, to facilitate the selection and matching of the trellis and heightening components according to different installation environments, the second component is provided with a trellis on its outer side, and the trellis is an L-shaped trellis; or, the upper end of the horizontal support is provided with a heightening component, the upper end of the heightening component is provided with a first trellis, an installation gap is left between the heightening component and the vertical support, the outer side of the vertical support is provided with a second trellis, and the lower part of the second trellis is located within the installation gap. Both the first trellis and the second trellis are used after being cut from L-shaped trellises.

[0017] Furthermore, to provide a more convenient positioning and installation effect for the trellis and heightening components according to different installation environments, the upper end of the horizontal support body is provided with a horizontal installation groove, and one side of the vertical support body is provided with a vertical installation groove. The horizontal and vertical installation grooves are connected. The horizontal section of the L-shaped trellis is located in the horizontal installation groove, and the vertical section of the L-shaped trellis is located in the vertical installation groove; or, the heightening component is located in the horizontal installation groove, the first trellis is located at the upper end of the heightening component, and the second trellis is located in the vertical installation groove. Both the first and second trellises are cut from L-shaped trellises for use.

[0018] Furthermore, in order to improve the structural stability after the heightening component is installed, anchors are provided on the outer periphery of the heightening component.

[0019] Furthermore, in order to improve the structural stability of the horizontal support installation and to guide the construction thickness of the rigid concrete layer of the roof, the horizontal support is provided with an upper radial outer edge and a lower radial outer edge. The upper radial outer edge is located at the upper end of the horizontal support, and the lower radial outer edge is located below the upper radial outer edge. The exhaust pipe pre-reserved head and through hole are both located below the lower radial outer edge.

[0020] Furthermore, in order to enable the vertical opening to better facilitate the transition connection between pipe connections, the vertical opening includes a tapered connecting section that connects to the pipe connection.

[0021] This invention also provides a method for constructing horizontal rainwater drainage on roofs, comprising the aforementioned multifunctional drain outlet fitting for horizontal rainwater drainage on roofs, including the following steps: S1: Structural layer construction; S2: Install the first component on the structural layer at the corner of the parapet wall; S3: Construction of concrete slope-finding layer (this item is not included when sloping a structure). S4: Waterproof membrane installation, seal the waterproof membrane into the waterproof membrane sealing groove; S5: Construction of thermal insulation layer; S6: Install the second component inside the thermal insulation layer and connect the exhaust pipe pre-installed head to the exhaust pipe inside the thermal insulation layer; S7: Mortar protective layer construction; S8: Construction of rigid concrete surface layer.

[0022] The beneficial effects of this invention are as follows: In this technical solution, since the first component and the second component are set separately, they can be installed in an adaptable manner with existing waterproofing construction steps. After the first component is installed, since the periphery of the vertical open part and the horizontal extension part are provided with waterproof membrane closing grooves, the waterproof membrane closing construction can be conveniently realized before the second component is installed. The waterproof membrane closing grooves provided around the periphery of the vertical open part and the horizontal extension part mainly solve the problem of the membrane end cracking after the waterproof membrane ages.

[0023] Since the opening includes a vertical opening and a horizontal extension, with the horizontal extension extending outward from the lower end of the vertical opening, the vertical support of the second component connects to the vertical opening, and the horizontal support of the second component connects to the horizontal extension. Both the vertical support and the horizontal support are connected to the opening. This design is well-suited for locations with parapet walls, meeting the requirements for horizontal drainage and achieving better horizontal drainage.

[0024] Because the transverse support has a pre-installed vent pipe and a through hole, and includes a baffle extending downwards from its upper end, with the outer side of the baffle being the outer channel and the inner side being the inner channel, vertical drainage will not affect the thermal insulation layer. Since both the pre-installed vent pipe and the through hole are connected to the outer channel, and an opening connects the outer channel to the transverse extension, and this opening connects to the inner channel, and the inner channel connects to the vertical opening, after the second component is installed, the pre-installed vent pipe is connected to the vent pipe within the thermal insulation layer. Therefore, when water enters the vent pipe, it can be discharged sequentially through the pre-installed vent pipe, the outer channel, the inner channel, the vertical opening, and the pipe connection. Simultaneously, the venting effect of the insulation layer can also be achieved by connecting it with the vent pipe inside the insulation layer, with the venting path being the same as above. Since there are through holes on the horizontal support, and these through holes are connected to the outer channel, after the second component is installed, the through holes are located inside the insulation layer. Therefore, when water seeps into the insulation layer, the water can be discharged from the through holes to the outer channel, and then discharged sequentially through the inner channel, the vertical opening, and the pipe connection. At the same time, the through holes can also achieve the venting effect of the insulation layer, with the venting path being the same as above. In addition, since there is a channel opening between the outer channel and the horizontal extension, and the channel opening is connected to the inner channel, the channel opening not only achieves the connection between the outer channel and the inner channel, but also ensures the natural air intake effect after the water that has leaked from the rigid concrete surface into the insulation layer is discharged.

[0025] In summary, this technical solution changes the traditional single function of roof drainage outlets. It goes beyond basic roof drainage, enabling drainage, ventilation, and air intake within the thermal insulation layer. It effectively removes accumulated water and moisture from the insulation layer, thus solving the problems of rainwater drainage, water accumulation in the insulation layer, ventilation, and air intake. Furthermore, it addresses the issue of water accumulation in the insulation layer caused by aging of exposed roof vent pipes. This solution solves the problem of roof leaks due to the inability to drain water from the insulation layer in existing designs. It also addresses the issue of rigid concrete being constantly soaked in water within the interlayer, leading to a significantly shortened lifespan of the rigid concrete. Additionally, it resolves the problem of aging and cracking of the waterproof membrane at the drainage outlet, while simultaneously meeting the requirements for lateral drainage, resulting in better lateral drainage performance.

Detailed Implementation

[0028] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0029] Example 1: like Figures 1-23 As shown, this embodiment provides a multi-functional roof rainwater horizontal drainage outlet fitting, including a first component 1 and a second component 2. The first component 1 includes an open portion and a pipe connection portion 1.1, which are connected through each other. The pipe connection portion 1.1 is connected to an external pipe. Preferably, the inner diameter of the pipe connection portion 1.1 is greater than or equal to 160mm. Figure 6 , Figure 8 As shown, the opening includes a vertical opening 1.2 and a horizontal extension 1.3. The horizontal extension 1.3 extends outward from the lower end of the vertical opening 1.2. Preferably, in order to better guide the direction of water flow, the horizontal extension 1.3 has a sloping surface 1.5 that extends downward towards the vertical opening 1.2. Both the vertical opening 1.2 and the horizontal extension 1.3 are provided with waterproof membrane sealing grooves 3 around their perimeters. The second component 2 includes a vertical support 2.1 and a horizontal support 2.2. The vertical support 2.1 is connected to the vertical opening 1.2, and the horizontal support 2.2 is connected to the horizontal extension 1.3. Both the vertical support 2.1 and the horizontal support 2.2 are connected to the opening. The transverse support 2.2 is provided with an exhaust pipe pre-reserved head 6 and a through hole 7. The transverse support 2.2 includes a baffle 2.4 extending downward at an incline from the upper port 2.3 of the transverse support 2.2. The outer side of the baffle 2.4 is an outer channel 4, and the inner side of the baffle 2.4 is an inner channel 5. The exhaust pipe pre-reserved head 6 and the through hole 7 are both connected to the outer channel 4. A channel opening 8 is left between the outer channel 4 and the transverse extension 1.3. The channel opening 8 is connected to the inner channel 5. The inner channel 5 is connected to the vertical open part 1.2. Specifically, in order to facilitate the guidance of water flow from the outer channel 4, the channel opening 8 is located at the upper end of the slope surface 1.5.

[0030] In this technical solution, since the first component 1 and the second component 2 are set separately, they can be installed in an adaptable manner with existing waterproofing construction steps. After the first component 1 is installed, since the periphery of the vertical open portion 1.2 and the horizontal extension portion 1.3 are provided with waterproof membrane closing grooves 3, the closing construction of the waterproof membrane 24 can be easily carried out before the installation of the second component 2. The waterproof membrane closing grooves 3 provided around the periphery of the vertical open portion 1.2 and the horizontal extension portion 1.3 mainly solve the problem of the membrane ends cracking after the waterproof membrane ages.

[0031] Since the opening includes a vertical opening 1.2 and a horizontal extension 1.3, with the horizontal extension 1.3 extending outward from the lower end of the vertical opening 1.2, the vertical support 2.1 of the second component 2 connects to the vertical opening 1.2, and the horizontal support 2.2 of the second component 2 connects to the horizontal extension 1.3. Both the vertical support 2.1 and the horizontal support 2.2 are connected to the opening. This design is well-suited for locations with parapet walls 17, meeting the requirements for horizontal drainage and achieving better horizontal drainage.

[0032] Because the transverse support 2.2 is equipped with an exhaust pipe pre-installed head 6 and a through hole 7, and the transverse support 2.2 includes a baffle 2.4 extending downwards at its upper port 2.3, with the outer side of the baffle 2.4 being an outer channel 4 and the inner side being an inner channel 5, the baffle 2.4 effectively distinguishes between the outer channel 4 and the inner channel 5. Therefore, vertical drainage will not affect the thermal insulation layer 25. Furthermore, the exhaust pipe pre-installed head 6 and the through hole 7... All are connected to the outer channel 4. A channel opening 8 is provided between the outer channel 4 and the transverse extension 1.3. Channel opening 8 connects to the inner channel 5, which in turn connects to the vertical opening 1.2. That is, after installing the second component 2, the exhaust pipe pre-installed head 6 is connected to the exhaust pipe 21 within the thermal insulation layer 25. When water enters the exhaust pipe 21, it can sequentially pass through the exhaust pipe pre-installed head 6, the outer channel 4, the channel opening 8, the inner channel 5, the vertical opening 1.2, and the pipe. The connecting part 1.1 drains water. At the same time, it can also achieve the venting effect of the insulation layer 25 by connecting with the vent pipe 21 inside the insulation layer 25. The venting path is the same as above. Since the transverse support 2.2 is provided with a through hole 7, which is connected to the outer channel 4, after the second component 2 is installed, the through hole 7 is located inside the insulation layer 25. When the insulation layer 25 is in a state of water seepage, the water can be drained from the through hole 7 to the outer channel 4, and then discharged through the inner channel 5, the vertical opening 1.2 and the pipe connecting part 1.1 in sequence. At the same time, the through hole 7 can also achieve the venting effect of the insulation layer 25. The venting path is the same as above. In addition, since there is a channel opening 8 between the outer channel 4 and the transverse extension 1.3, which is connected to the inner channel 5, the channel opening 8 not only realizes the connection between the outer channel 4 and the inner channel 5, but also ensures the natural air intake effect after the water that has leaked from the rigid concrete surface layer 27 into the insulation layer 25 is drained.

[0033] In summary, this technical solution changes the traditional single function of roof drainage outlets. It goes beyond basic roof drainage, enabling drainage, ventilation, and air intake within the thermal insulation layer 25. It effectively removes accumulated water and moisture from the thermal insulation layer 25, thus solving the problems of rainwater drainage, water accumulation in the thermal insulation layer 25, ventilation, and air intake. Furthermore, it addresses the issue of water accumulation in the thermal insulation layer 25 caused by aging of exposed roof vent pipes. This technical solution solves the problem of roof leaks caused by the inability to drain water from the thermal insulation layer 25 in the existing design. It also addresses the problem of the rigid concrete layer being constantly soaked in water within the interlayer, resulting in a significantly shortened lifespan. Additionally, it solves the problem of aging and cracking of the waterproof membrane 24 at the drainage outlet, while simultaneously meeting the requirements for lateral drainage, thus achieving better lateral drainage performance.

[0034] Example 2: This embodiment is an optimization based on the above embodiment 1.

[0035] To achieve a better sealing effect for the waterproof membrane 24, the sealing groove 3 on the vertical open portion 1.2 is connected to the sealing groove 3 on the horizontal extension portion 1.3, that is, as shown... Figure 8 As shown, the waterproof membrane closing groove 3 located on the vertical open portion 1.2 is a vertical closing groove 3.5, and the waterproof membrane closing groove 3 located on the horizontal extension portion 1.3 is a horizontal closing groove 3.6. The vertical closing groove 3.5 and the horizontal closing groove 3.6 are connected.

[0036] Example 3: This embodiment is an optimization based on the above embodiment 2.

[0037] To facilitate the finishing of the waterproof membrane 24 on the ground, such as Figure 6 As shown, the waterproof membrane end groove 3 on the transverse extension 1.3 includes a lower guide portion 3.1 and an upper limit portion 3.2. The end of the waterproof membrane 24 on the ground is located in the area between the lower guide portion 3.1 and the upper limit portion 3.2. The length of the upper limit portion 3.2 is less than the length of the lower guide portion 3.1.

[0038] Better, such as Figure 8 As shown, the lower guide portion 3.1 includes a first horizontal guide portion 3.11, an inclined guide portion 3.12, and a second horizontal guide portion 3.13 arranged sequentially, with the upper limit portion 3.2 located above the second horizontal guide portion 3.13.

[0039] Specifically, such as Figure 8 As shown, the waterproof membrane end groove 3 on the vertical open portion 1.2 includes an inner limiting portion 3.3 and an outer guiding portion 3.4. The end of the waterproof membrane 24 on the wall is located in the area between the inner limiting portion 3.3 and the outer guiding portion 3.4. The length of the inner limiting portion 3.3 is less than the length of the outer guiding portion 3.4.

[0040] It should be noted that, as Figure 6 As shown, when installing the second component 2, it is necessary to ensure that the end of the vertical support 2.1 is aligned with the inner limiting part 3.3, so that the waterproof membrane 24 on the wall can smoothly enter the area between the inner limiting part 3.3 and the outer guide part 3.4 during the finishing construction.

[0041] Example 4: This embodiment is an optimization based on the above embodiment 1.

[0042] In order to ensure the structural strength of the second component 2, and to facilitate the support and installation of the bracket 9 or the heightening component 10, a corner support 18 is provided between the vertical support 2.1 and the horizontal support 2.2. Specifically, the corner support 18 is L-shaped.

[0043] Example 5: This embodiment is an optimization based on the above embodiment 1.

[0044] To facilitate the selection and matching of the cover 9 and the heightening component 10 according to different installation environments, the outer side of the second component 2 is provided with a cover 9, which is an L-shaped cover; or, as... Figure 12 As shown, the upper end of the horizontal support 2.2 is provided with a heightening component 10, the upper end of the heightening component 10 is provided with a first sieve 9.1, and there is an installation gap between the heightening component 10 and the vertical support 2.1. The outer side of the vertical support 2.1 is provided with a second sieve 9.2, and the lower part of the second sieve 9.2 is located within the installation gap. Both the first sieve 9.1 and the second sieve 9.2 are used after being cut from an L-shaped sieve.

[0045] Example 6: This embodiment is an optimization based on the above embodiment 5.

[0046] To provide a more convenient positioning and installation effect for the bracket 9 and the heightening component 10 according to different installation environments, such as Figure 18 As shown, the upper end of the horizontal support 2.2 is provided with a horizontal mounting groove 12, and one side of the vertical support 2.1 is provided with a vertical mounting groove 13. The horizontal mounting groove 12 and the vertical mounting groove 13 are connected. The horizontal section of the L-shaped bracket is located in the horizontal mounting groove 12, and the vertical section of the L-shaped bracket is located in the vertical mounting groove 13. Alternatively, the heightening component 10 is located in the horizontal mounting groove 12, the first bracket 9.1 is located at the upper end of the heightening component 10, and the second bracket 9.2 is located in the vertical mounting groove 13. Both the first bracket 9.1 and the second bracket 9.2 are used after being cut from the L-shaped bracket.

[0047] Considering the design cost of the product, the first sieve 9.1 and the second sieve 9.2 can be cut from L-shaped sieves on the installation site.

[0048] It should be noted that a corner support 18 is provided between the vertical support 2.1 and the horizontal support 2.2. Specifically, the corner support 18 is L-shaped. The vertical section of the L-shaped corner support 18 constitutes the lateral limiting part of the horizontal mounting groove 12, and the horizontal section of the L-shaped corner support 18 constitutes the lateral limiting part of the vertical mounting groove 12.

[0049] Example 7: This embodiment is an optimization based on the above embodiment 5.

[0050] To improve the structural stability of the heightening component 10 after installation, an anchor 14 is provided on the outer periphery of the heightening component 10.

[0051] Example 8: This embodiment is an optimization based on the above embodiment 1.

[0052] To improve the structural stability of the horizontal support 2.2 and to guide the construction thickness of the rigid concrete roof layer, the horizontal support 2.2 is provided with an upper radial outer edge 15 and a lower radial outer edge 16. The upper radial outer edge 15 is located at the upper end of the horizontal support 2.2, and the lower radial outer edge 16 is located below the upper radial outer edge 15. The exhaust pipe pre-drilled head 6 and the through hole 7 are both located below the lower radial outer edge 16. That is, during actual construction, the thickness of the mortar protective layer 26 on the ground is constructed based on the lower radial outer edge 16, and the thickness of the rigid concrete surface layer 27 on the ground is constructed based on the upper radial outer edge 15.

[0053] Preferably, to improve the structural stability of the vertical support 2.1 and to guide the construction thickness of the rigid concrete layer on the parapet wall side, the vertical support 2.1 is provided with an outer radial edge 19 and an inner radial edge 20. Specifically, the outer radial edge 19 is located at the outer end of the vertical support 2.1, and the inner radial edge 20 is located inside the outer radial edge 19. The waterproof membrane termination groove 3 on the vertical opening 1.2 is located inside the inner radial edge 20. That is, during construction, the thickness of the mortar protective layer 26 on the wall surface is based on the inner radial edge 20, and the thickness of the rigid concrete surface layer 27 on the wall surface is based on the outer radial edge 19.

[0054] Example 9: This embodiment is an optimization based on the above embodiment 1.

[0055] In order to enable the vertical opening 1.2 to better achieve the transition connection between the pipe connection 1.1, the vertical opening 1.2 includes a tapered connection section 1.4 that connects with the pipe connection 1.1.

[0056] Preferably, in order to ensure the structural strength of the first component 1 and the second component 2, both the first component 1 and the second component 2 are integrally formed structures.

[0057] Example 10: The present invention also provides a method for constructing horizontal rainwater drainage on roofs, including a multi-functional drain outlet fitting for horizontal rainwater drainage on roofs as described in Example 1, comprising the following steps: S1: Construction of structural layer 22; S2: Install the first component 1 onto the structural layer 22 at the corner of the parapet wall; S3: Construction of concrete slope layer 23 (this item is not included in structural slope finding); S4: Waterproof membrane 24 construction, the waterproof membrane 24 is closed into the waterproof membrane closing groove 3; S5: Thermal insulation layer 25 construction; S6: Install the second component 2 inside the thermal insulation layer 25 and the rigid concrete surface layer 27 to ensure that the drain outlet is neatly closed, and connect the exhaust pipe pre-reserved head 6 to the exhaust pipe 21 inside the thermal insulation layer 25. S7: Mortar protective layer 26 construction; S8: Construction of rigid concrete surface layer 27; S9: Add a roof paving layer 28. In this case, a heightening component 10 can be added to ensure a neat finish at the drainage outlet.

[0058] This technical solution provides a multi-functional roof rainwater horizontal drainage pipe fitting with an aesthetically pleasing drainage outlet edge. Preferably, the first component 1, the second component 2, the purlin 9, the first purlin 9.1, and the second purlin 9.2 are made of PVC material. The purpose of this technical solution is to ensure smooth drainage from the roof drainage outlet, high-quality and aesthetically pleasing edge finishing, and to solve the problems of rainwater drainage, water accumulation in the thermal insulation layer 25, and ventilation and air intake on the roof.

[0059] This technical solution can solve the problems of rainwater drainage, water accumulation in the thermal insulation layer, and ventilation and air intake on the roof all at once. It also changes the original roof design and construction method, reducing the risk of roof leakage after the project is completed.

[0060] It should be noted that this technical solution not only solves the problem of roof leakage caused by the inability to drain water from the existing thermal insulation layer 25 in a timely manner, but also addresses the issue of the rigid concrete layer being constantly soaked in water in the interlayer, resulting in a significantly shortened service life. Furthermore, it resolves the problem of aging and cracking of the waterproof membrane 24 at the drainage outlet, while also meeting the requirements for lateral drainage, thus achieving a better lateral drainage effect.

[0061] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
