Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to an inverted slope roof planting gutter structure system. Background Art

[0002] Water shortages, water pollution, and urban flooding—three major water resource issues—are widespread worldwide and a major constraint on urban development. Under traditional urban construction models, hardened roads and reinforced concrete buildings often serve as the primary load-bearing structures, resulting in poor infiltration capacity. Consequently, heavy rains are primarily controlled through "gray" infrastructure such as pipelines and pumping stations, with planning and design philosophies focused on "rapid drainage" and "end-to-end concentration." This often results in flooding every time it rains, and rapid alternations between drought and flooding. Consequently, the concept of "sponge city" construction and "sponge-type architecture," with its new low-impact development model, has emerged and has become a hot topic in academic and practical research worldwide in recent years.

[0003] Sponge cities are a new generation of urban stormwater management concepts. They enable cities to adapt to environmental changes and respond to natural disasters caused by rainwater, acting like sponges. They possess excellent water absorption, storage, infiltration, and purification capabilities. Their construction adheres to the principle of ecological priority, combining natural approaches with artificial measures. Through a variety of technical approaches, including "infiltration, retention, storage, purification, utilization, and drainage," they achieve a virtuous urban hydrological cycle, improve the infiltration, storage, purification, utilization, and discharge capacity of runoff rainwater, and maintain or restore the city's sponge function. The sponge structures required for sponge city construction include natural water systems such as rivers, lakes, and ponds, as well as green spaces, gardens, permeable pavements, and buildings. Society attaches great importance to the development and construction of sponge cities, and many cities have formulated sponge city construction plans. The guiding concepts for urban development planning and design, as well as architectural design and construction, are gradually shifting from "rapid drainage" and "end-of-pipe centralized" control to "slow drainage and slow release" and "source-dispersed" control, aiming to minimize and prevent flooding disasters and their impacts while effectively collecting and utilizing rainwater.

[0004] In the existing slope roof gutter project, the conventional practice is to place the gutter on one side of the slope roof. As a single-function component, the gutter cannot play its intended function and role. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings and defects of the existing technology and to provide an inverted slope roof planting gutter structure system with drainage and storage functions.

[0006] An inverted slope roof planting gutter construction system comprises, from bottom to top, a reinforced concrete floor slab, a slope leveling layer, a leveling layer, a root-penetration-resistant waterproof layer, a protective layer, a ceramsite drainage / water storage layer, a filtration layer, planting soil, and a vegetation cover layer; an infiltration drainage / water storage pipe with an infiltration function is arranged inside the ceramsite drainage / water storage layer, and water holes are provided on the pipe wall of the infiltration drainage / water storage pipe.

[0007] Wherein, the protective layer is formed by C20 fine stone concrete.

[0008] Wherein, the leveling layer is formed by cement mortar.

[0009] Wherein, the slope leveling layer is formed by lightweight aggregate concrete.

[0010] Wherein, the filter layer is formed by geotextile.

[0011] Wherein, the infiltration drainage / water storage pipe is connected to the rainwater collection and utilization system.

[0012] Wherein, the rainwater collection and utilization system pipeline is connected in parallel to the water reservoir.

[0013] Wherein, the infiltration drainage / water storage pipe is connected to the rainwater collection and utilization system through the rainwater collection and utilization system trunk pipe.

[0014] Wherein, the infiltration drainage / water storage pipe is connected to the centralized rainwater discharge outlet, and the centralized rainwater discharge outlet is connected to the rainwater collection and utilization system.

[0015] The infiltration drainage / water storage pipe includes a first pipe arranged along the length of the gutter and a plurality of spaced-apart second pipes vertically connected to the first pipe.

[0016] Under the premise of meeting the functional requirements of the building, the utility model breaks the traditional roof gutter construction method and innovatively sets the gutter on the structural layer below the sloping roof, collects water in an inverted manner, and combines it with landscape planting to beautify the building and the surrounding environment, while weakening the heavy feeling of the conventional building eaves. At the same time, the gutter can also be used as a canopy for the lower layer of the building, saving construction costs.

[0017] The system of the utility model utilizes drainage (storage) facilities arranged in the gutter to collect and store rainwater, and at the same time cooperates with the rainwater collection and utilization system and the water storage facilities to achieve reverse irrigation of vegetation planted in the gutter.

[0018] The system of the utility model takes advantage of the rainwater collection function of the sponge-type building to achieve the purpose of controlling and utilizing rainwater (surplus water), and plays a role in saving water, energy and emission reduction while alleviating the pressure of urban waterlogging.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Explanation or description of terms:

[0024] Sponge City, internationally known as "low-impact development and stormwater system construction," is a new urban stormwater management concept that draws on the properties of sponges in nature: their exceptional ability to absorb, store, infiltrate, and purify water. This allows them to adapt to environmental changes and natural disasters while maintaining resilience and adaptability. Sponge City construction improves the storage, infiltration, and purification of rainwater within urban areas, while also promoting the utilization of rainwater resources and protecting the ecological environment.

[0025] Sponge architecture is a concept and approach to architectural development that leverages the building's inherent ability to absorb, store, infiltrate, and slowly release rainwater through enhanced urban planning and construction management, effectively controlling rainwater runoff and achieving natural accumulation, infiltration, and purification. The collected rainwater is then comprehensively treated and then controlled and utilized through appropriate means.

[0026] Inverted gutter: Generally set at the edge of the roof, it refers to the concave part between the two spans of the building roof. It is a groove used to collect roof drainage. The collected rainwater is collected and discharged to the ground through a vertical centralized rainwater outlet. The inverted gutter in this system is set at the next structural layer where the sloping roof is located. It is used to collect unorganized drainage on the roof. The gutter also serves as a canopy for the next layer.

[0027] Awning: It is a building structure installed at the entrance or exit of a building or above the top balcony to block rain, wind and prevent injuries from falling objects from high altitude.

[0028] In terms of sponge city construction, there are existing national standards such as the "Parity Standard for Sponge City Construction" GB / T 51345-2018 and the national building standard design atlas "Sponge-type Buildings and Community Rainwater Control and Utilization" 17S705 for reference. Based on a systematic study of the existing national standards and atlases, the utility model improves and optimizes the conventional practices of building gutter structure design, and provides a new inverted planting gutter structure system with drainage and storage functions.

[0030] In some embodiments, the protective layer is formed of C20 fine stone concrete, or other materials, but not limited thereto. In some embodiments, the leveling layer is formed of cement mortar, such as 1:3 cement mortar, with a thickness of 15 mm. In some embodiments, the slope layer is formed of lightweight aggregate concrete, or other materials, but not limited thereto. In some embodiments, the filter layer is formed of geotextile, or other materials, but not limited thereto. In some embodiments, the infiltration drainage / water storage pipe is connected to a rainwater collection and utilization system. In some embodiments, the rainwater collection and utilization system pipeline is connected in parallel to the reservoir. In some embodiments, the infiltration drainage / water storage pipe is connected to the rainwater collection and utilization system through the rainwater collection and utilization system main pipe.

[0031] In some embodiments, the infiltration drainage / storage pipe is connected to a centralized rainwater drainage outlet, which is connected to a rainwater collection and utilization system. In some embodiments, the infiltration drainage / storage pipe includes a first pipe arranged along the length of the gutter and a plurality of spaced-apart second pipes perpendicularly connected to the first pipe.

[0032] The system of the utility model can be applied to reinforced concrete structures with unorganized free drainage of sloping roofs, and reinforced concrete floors and roof structures can be poured during the construction of the main building.

[0033] The system brief construction process of this utility model is as follows:

[0034] (1) After the main construction is completed, a light aggregate concrete sloping layer is constructed on the upper part of the gutter concrete, with the thinnest part not less than 30mm. (2) A 1:3 cement mortar leveling layer is constructed with a thickness of 15mm. (3) A root-penetration-resistant waterproof layer is constructed, and both sides should be rolled up and pressed into the concrete eaves and the lower sub-frame of the curtain wall. (4) A C20 fine stone concrete protective layer is constructed. (5) After the infiltration drainage (storage) pipes are positioned according to the spacing, a ceramsite drainage and storage layer is laid, with the thinnest part not less than 100mm thick. The infiltration drainage (storage) pipes are connected to the rainwater collection system main pipe, or a centralized rainwater discharge outlet that has reliable use conditions and is reliably connected to the rainwater collection system, and are connected in parallel with the rainwater collection and utilization system pipelines uniformly installed in the site or residential area to send the collected rainwater to the reservoir. (6) Lay a 300g / m2 geotextile filter layer along the entire cross-section of the upper planting soil contact surface and the lower drainage (storage) layer, gluing or nailing the joints. (7) Backfill the planting soil along the inner side of the building gutter in layers, according to the specific requirements of the landscape professional. (8) Planting is carried out, and the construction is completed.

[0035] The utility model has an inverted slope roof planting gutter structure, such as Figure 1 as well as Figure 2 As shown, it is arranged outside the interior space of the building, that is, outside the interior space of the building and the interior space of the lower floor, and is connected to the building's external enclosure wall 31. On the interior side of the building, there is a protective railing 21 arranged inside the French window or glass curtain wall 41. The roof structure is as shown Figure 1 、 Figure 2 As shown, from bottom to top, there are reinforced concrete roof panels 61, cement mortar leveling layer 62, waterproof cushion layer 63, thermal insulation layer 64, fine stone concrete leveling layer 65, water strips 66, tile hanging strips 67 and flat tile surface layer 68. The corresponding gutter position has a drain pipe 51, which can drain rainwater into the gutter. On rainy days, rainwater flows to the lowest point along the inclined water strips on the inclined structure roof and is discharged into the gutter through the drain pipe 51. The front end of the inclined structure roof is an L-shaped structure, which is convenient for intercepting rainwater that flows to the lowest point along the inclined water strips and allowing it to be discharged into the gutter through the drain pipe 51.

[0036] Compared with conventional inverted slope roof planting gutter construction system, this utility model has the following characteristics:

[0037] (1) The innovation of this utility model is to adopt an inverted layout, placing the gutter in the next structural layer where the sloping roof panel is located, and using the unorganized free fall method to slow down the rainwater and concentrate it in a short time. At the same time, combined with the installation of drainage (storage) facilities at the bottom of the gutter, artificial measures are used to achieve the infiltration and collection of surface runoff rainwater by the building, reduce the terminal discharge pressure, achieve slow drainage and slow release, and reduce emissions at the source; effectively improve the defects of traditional gutter water collection, which is first segmented and then concentrated at the terminal.

[0038] The system of the utility model inverts the gutter originally set at the roof layer of the building and places it at the next structural layer where the sloping roof panel is located. At the same time, the roof drainage no longer adopts a unified organized drainage. Instead, the slope of the sloping roof is controlled and the water falls freely in an unorganized manner to slow down the concentrated convergence of rainwater in a short period of time, while ensuring the original function of the building gutter. At the same time, the internal space of the gutter is utilized to set an infiltration pipe with drainage (storage) function at the bottom, and the outside is covered with a drainage (storage) layer. The soil within the gutter range acts as a "sponge" medium to slowly infiltrate and store surface runoff rainwater, reduce the pressure of terminal discharge, and achieve source emission reduction; it effectively improves the defect of traditional gutters that water is first collected in sections and then discharged in a centralized manner at the end. At the same time, the rainwater that penetrates to the bottom can be connected to the outdoor rainwater collection well through the drainage (storage) facilities, and finally to the reservoir through the rainwater collection system trunk pipe, so as to realize the collection and storage of rainwater and alleviate the pressure of urban waterlogging.

[0039] (2) Combined with the inverted layout, the internal space of the gutter is cleverly used for planting. The gutter is no longer a component with a single function. The unique landscape effect it creates is integrated with the building to form a unique and harmonious landscape architecture, which embellishes the life of users, makes people feel relaxed and happy, and adds beauty to the building and the surrounding environment.

[0040] The system of the utility model makes full use of the layout of the inverted gutter, optimizes the use of the internal space of the gutter, forms a landscape space that can be arranged around the building by planting landscape vegetation inside, and forms a dynamic and balanced landscape effect through certain processing and expression methods, adding beauty to the building and the surrounding environment.

[0041] The internal space of the gutter of the utility model is similar to a breathable and permeable sponge, and has good conditions for plant growth. At the same time, the runoff rainwater collected on the building roof can be effectively used as a water source for irrigation.

[0042] (3) The inverted gutter of the utility model can replace the traditional gutter arranged in a circle on the roof, reducing the heavy feeling at the eaves of the building and reducing the load on the end of the building. At the same time, it can also be used as a canopy for the lower floor of the building, achieving multiple goals at one stroke, reducing the number of building components used, beautifying the building facade, and saving construction costs.

[0043] (4) The drainage (storage) facilities in the planting gutter of the utility model are interconnected with the external rainwater collection and utilization system, pipelines, and water storage facilities, and have complete systematization and reliability. The stored rainwater after treatment can also be reused through the system to achieve reverse irrigation of the vegetation in the gutter, thereby achieving the effect of water conservation, energy conservation and emission reduction.

[0044] The drainage (storage) pipes and ceramsite drainage (storage) layers inside the system of the present invention are relatively permeable bodies, which can realize the two functions of forward drainage and reverse water storage. In engineering practice, it should be connected to the rainwater collection system main pipe or a centralized rainwater outlet that has reliable use conditions and is reliably connected to the rainwater collection system, and connected in parallel with the rainwater collection and utilization system pipeline uniformly set up in the site or residential area. The collected rainwater is stored in a dedicated water tank after being processed by the system. The water source in the water tank can also be reused after being pressurized by the system and used as water for irrigation of vegetation in the gutter. The system of the present invention can realize a full set of processes such as the collection, control, storage and reuse of runoff rainwater, forming a complete system with good reliability. At the same time, it can effectively save water and play a role in energy conservation and emission reduction.

[0045] This utility model system is based on the design concept of sponge city and sponge-type buildings. It aims to utilize and improve the construction measures of traditional buildings to make them into "sponge bodies" with natural regulating capabilities. The main functions are as follows:

[0046] 1) Reduce urban consumption of natural water resources, effectively utilize water resources, realize “collection-storage-reuse”, and reduce excessive consumption and dependence of cities on water resources.

[0047] 2) Enable buildings to have better hydrological regulation capabilities, reduce the occurrence of urban waterlogging, and at the same time improve the urban environment and the quality of life of residents.

[0048] 3) Protect the ecological environment, improve the ecological functions of cities, protect natural water bodies such as rivers and lakes, improve ecological functions through the construction of sponge-type buildings, and promote sustainable development.

[0049] 4) As people pay more and more attention to environmental protection and resource utilization, the construction of sponge buildings will gradually become an emerging industry, creating a large number of employment opportunities and economic benefits for society.

[0050] 5) The architectural structure and construction materials of the system of this utility model are all technologically mature products that have been factory-produced in batches and can be directly constructed and installed on site. They have the characteristics of convenient procurement, low cost, short construction period, high construction efficiency, and small environmental impact. They are in line with the future development direction of sponge cities and green construction (building materials) technology.

[0051] 6) The system of this utility model is based on the concept of sustainable development, fully responds to the development requirements of sponge cities and green buildings, combines urban development planning and the guiding ideology of sponge buildings, fully retains the traditional advantages of traditional architectural design and construction technology, and at the same time incorporates the results of technological innovation. It is in line with the future development direction of green construction technology and has great application prospects.

[0052] 7) The utility model system can be flexibly adjusted to add or remove layers according to different environmental categories, building functions, styles, and structural types. The accessories and building materials used can be adjusted according to different building types, building fire resistance levels, and earthquake resistance requirements in different regions. It can meet various design requirements, has strong practicality, and has certain social promotion and economic value.
