Description

Technical Field

[0001] This utility model belongs to the field of building drainage technology, specifically relating to a combined drainage gutter. Background Technology

[0002] Large terraces or roofs are common in public buildings, especially high-rise towers with attached podiums, which often have both large terraces and roofs. Both terraces and roofs require drainage design; however, due to their large size, the cumulative slope drop of the terraces and roofs, as well as the slope of the gutters, can cause a series of problems.

[0003] First, the cumulative slope difference results in a thicker building surface layer, which undoubtedly increases the structural load and poses a potential threat to the stability and safety of the building structure. Second, to achieve effective drainage, a large area of ​​slab reduction is often required, which reduces the clear height of the lower floor and affects the comfort and functionality of the space on that floor. Furthermore, if the finished surface level of the terrace and roof is raised instead of reducing the slab, steps must be climbed from inside the building to reach these areas, which not only affects the spatial experience but also increases the risk of rainwater backflow into the building.

[0004] While increasing the number of rainwater inlets can mitigate some of the slope reduction in gutter drainage, this approach introduces new problems by increasing the number of rainwater downpipes or horizontal pipes. When all drainage downpipes in high-rise towers are required to be located around the core tube, the resulting contradictions become particularly pronounced, severely impacting the ceiling height of the next floor and environmental noise control. Therefore, to address the shortcomings of existing technologies, a combined drainage gutter structure is needed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a combined drainage gutter that can control the drop value of large-area terraces and roof slabs, thereby controlling the thickness of the building surface layer, ensuring the net height of the next floor, and ensuring smooth drainage.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A combined drainage gutter includes a building drainage ditch (1) and a structural drainage ditch (2). The building drainage ditch (1) is set along the outer side of the terrace (4) or roof (6) and is formed by utilizing the thickness of the building surface layer. The structural drainage ditch (2) is set in the middle of the terrace (4) or roof (6) and at the boundary (5) between the interior and exterior through a structural folding plate. The bottom of the slab of the structural drainage ditch (2) is flush with the bottom of the structural beam (7). At the intersection of the structural drainage ditch (2) and the structural beam (7), a DN150 steel sleeve (3) is pre-embedded at the preset elevation of the structural beam (7) according to the slope design in the structural drainage ditch.

[0008] In a preferred embodiment of the present invention, the building drainage ditch (1) includes a first building drainage ditch (1-1) and a second building drainage ditch (1-2). The first building drainage ditch (1-1) is set along the outer side of the terrace (4) and the roof (6) on the open side, and the second building drainage ditch (1-2) is set along the outer side of the roof (6).

[0009] In a preferred embodiment of this utility model, the structural drainage ditch (2) includes a fourth structural drainage ditch (2-4), a second structural drainage ditch (2-2), a first structural drainage ditch (2-1), a third structural drainage ditch (2-3), and a fifth structural drainage ditch (2-5) connected in sequence. The first structural drainage ditch (2-1) is located at the indoor-outdoor boundary (5). The second structural drainage ditch (2-2) and the third structural drainage ditch (2-3) both extend from the indoor-outdoor boundary (5) through the middle of the roof (6) to the outer side of the terrace (4). The fourth structural drainage ditch (2-4) and the fifth structural drainage ditch (2-5) are located at both ends of the outer side of the roof (6). The second building drainage ditch (1-2) is located between the second structural drainage ditch (2-2) and the third structural drainage ditch (2-3).

[0010] In a preferred embodiment of this utility model, a DN150 steel sleeve (3) is provided on the first structural drainage ditch (2-1), the second structural drainage ditch (2-2), the third structural drainage ditch (2-3), the fourth structural drainage ditch (2-4), and the fifth structural drainage ditch (2-5).

[0011] In a preferred embodiment of this utility model, the first structural drainage ditch (2-1) is connected to a side-drainage rainwater hopper, the side-drainage rainwater hopper is connected to a horizontal rainwater pipe, and the horizontal rainwater pipe is connected to a rainwater downpipe near the roof to ensure smooth drainage.

[0012] In a preferred embodiment of this utility model, the structural drainage ditch (2) forms a certain drop with the building drainage ditch (1) through a local lowering plate, and the structural drainage ditch (2) has a slope to ensure smooth rainwater drainage.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model uses a combined structure of building drainage ditch and structural drainage ditch. The building drainage ditch is set along the outer side of the terrace or roof, utilizing the thickness of the building surface layer. The structural drainage ditch is set in the middle of the terrace or roof and at the boundary between the interior and exterior spaces through a structural folded plate. The bottom of the structural drainage ditch is flush with the bottom of the structural beam. Looking up from the interior space of the next floor, the bottom of the structural drainage ditch is flush with the bottom of the structural beam, and its interior appearance is similar to that of a conventional structural beam, effectively solving the problem of reduced interior height caused by large-area slab reduction.

[0015] (2) Install side-drainage rainwater hoppers and rainwater horizontal pipes in the structural drainage ditch at the boundary between indoor and outdoor areas of the terrace or roof. The rainwater horizontal pipes are connected to the rainwater risers, so that the rainwater risers can be concentrated around the core tube near the roof, effectively solving the problems of insufficient net height and environmental noise caused by the rainwater horizontal pipes passing through the indoor space.

[0016] (3) Depending on the specific plan of the terrace or roof, a building drainage ditch can be added between the structural drainage ditches, which can shorten the roof slope distance and reduce the thickness of the building surface layer, thereby further reducing the drop value of the terrace or roof and the structural load.

[0017] (4) The slope of the building drainage ditch is controlled within a reasonable range. The structural drainage channel forms a certain drop with the building drainage ditch through the local drop plate, and the slope of the structural drainage ditch is used to ensure smooth rainwater drainage and guarantee the drainage effect.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The terms "upper," "lower," "front," "rear," "left," and "right," etc., used when describing the installation position or direction of the structure or components in this embodiment are based on the orientation shown in the accompanying drawings. They are merely for convenience of description, used to distinguish the relative positions of various components or directions, and do not represent the orientation of the device or functional component in this embodiment during use.

[0022] like Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a combined drainage gutter, including a building drainage ditch 1 and a structural drainage ditch 2. The building drainage ditch 1 is set along the outer side of the terrace 4 or roof 6, utilizing the thickness of the building surface layer. The structural drainage ditch 2 is set in the middle of the terrace 4 or roof 6 and at the indoor / outdoor boundary 5 via a structural folded plate. The bottom of the structural drainage ditch 2 is flush with the bottom of the structural beam 7. At the intersection of the structural drainage ditch 2 and the structural beam 7, a DN150 steel sleeve 3 is pre-embedded at a predetermined elevation of the structural beam 7, according to the slope design within the structural drainage ditch. The DN150 steel sleeve 3 provides a channel for rainwater to flow between the structural drainage ditch 2 and the structural beam, ensuring that rainwater can be smoothly discharged along the designed path.

[0023] In this embodiment, the building drainage ditch 1 makes full use of the building's own structure and materials, without requiring excessive additional space, while effectively collecting rainwater from the exterior of the terrace 4 or roof 6. The design of the structural drainage ditch 2 ensures that, when viewed from the lower floor's interior space, its interior appearance resembles a conventional structural beam, avoiding the problem of compressing the lower floor's interior height due to the presence of the structural drainage ditch 2, and guaranteeing the comfort of the lower floor's space.

[0024] Specifically, the building drainage ditch 1 includes a first building drainage ditch 1-1 and a second building drainage ditch 1-2. The first building drainage ditch 1-1 is set along the outer side of the terrace 4 and the roof 6, while the second building drainage ditch 1-2 is set along the outer side of the roof 6. The structural drainage ditch 2 includes a fourth structural drainage ditch 2-4, a second structural drainage ditch 2-2, a first structural drainage ditch 2-1, a third structural drainage ditch 2-3, and a fifth structural drainage ditch 2-5 connected in sequence. The first structural drainage ditch 2-1 is located at the interior-exterior boundary 5. The second and third structural drainage ditches 2-2 and 2-3 both extend from the interior-exterior boundary 5 through the middle of the roof 6 to the outer side of the terrace 4, while the fourth and fifth structural drainage ditches 2-4 and 2-5 are located at both ends of the outer side of the roof 6. DN150 steel sleeves 3 are installed on the first, second, third, fourth, and fifth structural drainage ditches 2-1 and 2-2, 2-3, 2-4, and 2-5, respectively.

[0025] The first structural drainage ditch 2-1 is connected to a side-drainage rainwater hopper, which is connected to a horizontal rainwater pipe. The horizontal rainwater pipe connects to the rainwater downpipe near the roof, ensuring smooth drainage. This drainage path design allows rainwater to be discharged quickly and effectively. At the same time, by centrally locating the rainwater downpipes around the core tube near the roof, it avoids the cluttered distribution of rainwater downpipes and horizontal pipes in the indoor space, reduces the impact on the net height of the indoor space, and also reduces the environmental noise generated by rainwater flow.

[0026] Furthermore, based on the specific plan of the terrace 4 or roof 6, a second building drainage ditch 1-2 can be installed between the second structural drainage ditch 2-2 and the third structural drainage ditch 2-3, that is, an additional building drainage ditch 1 can be installed between the structural drainage ditches 2. The added building drainage ditch 1 can shorten the slope-finding distance of the terrace 4 and roof 6, reduce the thickness of the building surface layer, and thus further reduce the drop value of the terrace 4 and roof 6 and the structural load, making the entire combined drainage gutter more reasonable and efficient.

[0027] The slope of the building drainage ditch 1 is controlled within a reasonable range. The structural drainage ditch 2 forms a certain drop with the building drainage ditch 1 through a partial lowering of the slab, and the slope within the structural drainage ditch 2 ensures smooth rainwater drainage. The reasonable slope design and drop setting guarantee the flow speed and volume of rainwater in the drainage ditch, avoid rainwater accumulation, and ensure the normal operation of the drainage system. Looking up from the interior space of the lower floor, because the bottom of the structural drainage ditch is level with the bottom of the structural beam, its interior appearance is similar to that of a conventional structural beam, solving the problem of reduced interior height caused by a large area of ​​lowering the slab.

[0028] This utility model's combined drainage skylight, through reasonable structural design and drainage path planning, can effectively control the drop value of large-area terraces and roof slabs, reduce structural load, control the thickness of building surface layers, ensure the net height of the next floor, and ensure smooth drainage. At the same time, rainwater downpipes can be centrally located around the core tube near the roof, effectively solving the problems of insufficient net height and environmental noise caused by rainwater horizontal pipes passing through the indoor space. It has high practical value and promotion significance.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
