Description

Technical Field

[0001] This utility model relates to the field of building greening technology, and in particular to a prefabricated rooftop garden planting pool. Background Technology

[0002] Planting beds are artificial structures specifically designed for plant cultivation, widely used in urban roads, plazas, and rooftops. Their dimensions must be customized to suit the plant species and their growth needs, providing ample and suitable growing space. Currently, rooftop planting beds are commonly constructed using a tiered process, but this method has several drawbacks in practical applications: 1. In terms of construction and safety, the process of tiered planting beds is complex, requiring construction workers to build multiple layers sequentially, including structural, insulation, waterproofing, drainage, filtration, and planting soil layers. This demands high levels of professional skill from the workers and must be operated by qualified personnel. This characteristic significantly limits the popularization and promotion of rooftop gardens. Furthermore, the installation quality is easily affected by human factors such as material quality, construction techniques, and on-site conditions, which can easily create safety hazards on the roof. For example, improper material selection or non-standard construction can lead to uneven stress on the roof structure, significantly increasing the risk of leakage and collapse.

[0003] 2. Regarding water resource utilization and irrigation systems, tiered planting beds have a faster drainage rate but weaker water storage capacity, requiring frequent watering of the plants. This results in low rainwater utilization and high water consumption, contradicting current environmental protection principles of energy conservation and emission reduction. Furthermore, tiered planting beds require additional irrigation equipment, and blind spots can easily occur during irrigation, causing some plants to lack sufficient water, directly impacting normal plant growth and the overall landscape effect.

[0004] 3. In terms of landscape effect and function, due to water resource constraints, tiered planting ponds mostly use drought-resistant plants, resulting in a lack of landscape layering caused by the limited variety of plant species.

[0005] 4. In terms of heat insulation and maintenance, when using a thin-layer planting method, the heat insulation effect of the layered planting pool is poor; and potential structural hazards on the roof are difficult to detect in time, making subsequent maintenance not only difficult to operate, but also potentially causing secondary damage to the original roof structure during the maintenance process. Utility Model Content

[0006] The main purpose of this utility model is to propose a prefabricated rooftop garden planting bed, which aims to solve the technical problems of existing layered planting beds, such as complicated process, easy safety hazards, low rainwater utilization, large water consumption, and difficult maintenance and operation.

[0007] To achieve the above objectives, the present invention proposes a prefabricated rooftop garden planting bed, comprising a frame and a two-way filter. The two-way filter is installed inside the frame, and the cavity between the outer wall of the two-way filter and the inner wall of the frame forms a water supply and drainage channel. The frame has a waterproof layer, and the two-way filter is filled with planting soil.

[0008] Optionally, the side of the frame is provided with water supply and drainage through holes, and there are multiple assemblies of the frame and the bidirectional filter. The water supply and drainage through holes between adjacent frames are aligned with each other, and a connecting ring is provided in two water supply and drainage through holes of adjacent frames. The water supply and drainage through holes on the independent side of the frame are provided with sealing plugs.

[0009] Optionally, the water supply and drainage through hole is located in the middle of the side of the frame.

[0010] Optionally, a cross-shaped clip is provided at the connection point of the four frames.

[0011] Optionally, the sidewall of the bidirectional filter is a filter layer, and the lower part of the bidirectional filter is provided with multiple first structural reinforcing strips and multiple second structural reinforcing strips, the first structural reinforcing strips and the second structural reinforcing strips being perpendicular to each other and intersecting to form a mud and sand blocking grid.

[0012] Optionally, the bidirectional filter is provided with multiple support columns, which are located at the apex of the sediment blocking grid.

[0013] Optionally, a number of support members are provided between the outer bottom wall of the bidirectional filter and the inner bottom wall of the frame.

[0014] Optionally, the frame is provided with multiple supporting feet at its bottom.

[0015] Optionally, the frame and the bidirectional filter are provided with a cover plate on top.

[0016] The technical solution of this utility model has the following beneficial effects: When constructing the planting bed, workers first transfer the modular components to a suitable location on the roof. Then, they assemble the frame and the two-way filter into a unit. Based on the greening requirements of the area, multiple units are placed in appropriate positions and connected using connecting rings. Next, the drainage holes on the side of the frame not adjacent to other frames are sealed with plugs, and adjacent frames are connected using cross clamps. Finally, the cover is installed to complete the construction of the planting bed.

[0017] In terms of construction and safety, construction workers only need to assemble modular components, making the process simpler and allowing ordinary construction workers to complete the assembly work with low professional technical requirements. During construction, there is no need for professional construction operations such as surveying, nor is it necessary to build multiple functionally different layers sequentially. After assembly, the planting beds and the roof are independent of each other, and it is not likely to cause safety hazards to the roof.

[0018] In terms of water resource utilization and irrigation systems, water storage, drainage, and irrigation can be achieved through water supply and drainage channels, thus improving rainwater utilization and reducing water consumption. Furthermore, rainwater and irrigation water can be evenly distributed within each frame through the water supply and drainage openings, eliminating the need for complex additional irrigation equipment to achieve uniform irrigation, which helps ensure normal growth and overall landscape aesthetics.

[0019] In terms of landscape effect and functionality, the problem of water resource constraints has been solved, thus allowing for the selection of more non-drought-resistant plants, increasing plant species, and enriching the landscape layers.

[0020] In terms of thermal insulation and maintenance, the cavity formed between the bottom surface of the frame and the top surface of the roof, as well as the water supply and drainage channels, can all play a role in thermal insulation. Furthermore, relevant personnel can easily observe whether there are any structural hazards in the roof through the cavity formed between the bottom surface of the frame and the top surface of the roof, and it is also easy to dismantle the planting beds to repair any structural hazards. During the dismantling of the planting beds, no secondary damage will be caused to the original roof structure, which is far superior to the tiered planting bed process. Attached Figure Description

[0028] This utility model proposes a prefabricated rooftop garden planting pool.

[0029] like Figures 1 to 4As shown in Embodiment 1 of this utility model, the prefabricated rooftop garden planting bed includes a frame 1 and a two-way filter 2. The two-way filter 2 is installed inside the frame 1, and the cavity between the outer wall of the two-way filter 2 and the inner wall of the frame 1 forms a water supply and drainage channel 12. Specifically, the frame 1 is a prefabricated composite material product, similar to composite panels and composite pipes, and is made of various steel, plastic, and / or ceramic materials with different functions. The different material layers of the frame 1 (or the structural layers formed by combining different materials) have corresponding functions such as waterproofing, heat insulation, providing mechanical support, maintaining the overall shape, and bearing loads. Therefore, the frame 1 of this utility model is equivalent to the structural layer, heat insulation layer, and waterproof layer of the layered planting bed. Furthermore, the two-way filter 2 can both contain planting soil and filter water during rain to drain excess rainwater and during irrigation to introduce irrigation water, thus the double-layer filter containing planting soil is equivalent to the filter layer and planting soil layer of the layered planting bed. Furthermore, the drainage channel 12 formed by the cavity between the outer wall of the bidirectional filter 2 and the inner wall of the frame 1 can drain excess rainwater and introduce irrigation water, which is equivalent to the drainage layer of the tiered planting pond.

[0030] When constructing the planting beds, construction workers only need to assemble the modular frame 1 and the two-way filter 2, making the process simpler. Ordinary construction workers can complete the assembly work, requiring minimal technical expertise. During construction, no specialized operations such as measurement are needed, nor is it necessary to construct multiple functionally different layers sequentially. Once assembled, the planting beds and the roof are independent of each other, minimizing the risk of safety hazards to the roof.

[0031] Specifically, multiple supporting feet are provided at the bottom of the frame 1. The supporting feet include first feet 6 located at the four corners of the frame 1 and second feet 7 located in the middle of the frame 1. Both the first feet 6 and the second feet 7 provide support for the frame 1, thereby separating the bottom surface of the frame 1 from the top surface of the roof, preventing the frame 1 from directly contacting the roof surface, reducing heat exchange between the two, preventing the heat absorbed by the roof from damaging the plants in the planting bed, and also preventing uneven heating and cooling of the roof by irrigation water.

[0032] Furthermore, a cover plate 3 is provided on the top of the frame 1 and the bidirectional filter 2. The cover plate 3 can cover the water supply and drainage channel 12 between the frame 1 and the bidirectional filter 2, thereby reducing water evaporation, dust and impurity accumulation and preventing mosquito breeding, ensuring the smooth operation of water supply and drainage.

[0033] like Figure 1 , 2As shown in Figure 3, at least one water supply and drainage through-hole 11 is provided on each of the four sides of the frame 1. The number of assemblies of the frame 1 and the bidirectional filter 2 is multiple, and the water supply and drainage channels 12 of these multiple assemblies can be connected according to actual construction requirements. Specifically, the water supply and drainage through-holes 11 between adjacent frames 1 are aligned with each other. A connecting ring 4 is provided in two water supply and drainage through-holes 11 of adjacent frames 1. The connecting ring 4 is used to connect the water supply and drainage channels 12 of adjacent frames 1 and to prevent rainwater or irrigation water from leaking out from the gap between the two water supply and drainage through-holes 11. Furthermore, a sealing plug 5 is provided on the water supply and drainage through-hole 11 on the independent side of the frame 1. The sealing plug 5 seals the water supply and drainage holes on the side of the frame 1 not adjacent to other frames 1 to prevent rainwater or irrigation water from flowing out from the water supply and drainage holes. This design can connect multiple frames 1 and bidirectional filters 2 according to different construction needs, thereby meeting the different greening requirements of different buildings. It does not require specially designed planting pools with corresponding shapes and structures, nor does it require separate drainage and irrigation systems for each planting pool. It has many advantages such as strong versatility, low cost, and simple and convenient construction process.

[0034] Furthermore, the aforementioned water supply and drainage holes 11 are all located in the middle of the side of the frame 1. Excess rainwater, after overflowing the middle of the frame 1, is discharged through the water supply and drainage holes 11, the water supply and drainage channels 12 in the adjacent frame 1, and the drainage system. At the same time, rainwater and irrigation water can enter other frames 1 through the water supply and drainage holes 11 to achieve a uniform distribution effect. Water below the height of the water supply and drainage holes 11 serves as a reserve water inside the frame 1 for plants to absorb.

[0035] In this embodiment, a cross-shaped clip 8 is provided at the connection point of the four frame bodies 1. The cross-shaped clip 8 has a slot, which can simultaneously engage with the edges of the four corners of the frame bodies 1, thereby playing a role in auxiliary connection and fixation. Furthermore, the cover plate 3 has a notch for matching the cross-shaped clip 8 to facilitate the installation of the cover plate 3. In other embodiments, flanges can be provided at the four corners of the top surface of the cover plate 3, so that the slots of the cross-shaped clip 8 engage with the flanges to connect the four frame bodies 1.

[0036] like Figure 2 , 3As shown in Figure 4, the sidewall of the bidirectional filter 2 is a filter layer. Multiple first structural reinforcing strips and multiple second structural reinforcing strips are provided at the lower part of the bidirectional filter 2. The first and second structural reinforcing strips are perpendicular to each other and intersect to form a sediment blocking grid 21. The first and second structural reinforcing strips, along with the sediment blocking grid 21, provide support for the planting soil and block sediment through their reinforced structure. Specifically, multiple support columns 22 are provided inside the bidirectional filter 2, located at the apex of the sediment blocking grid 21. The support columns 22 serve multiple functions, including dispersing and dividing the planting soil, preventing stress concentration, dispersing and bearing the pressure from the planting soil and plants, and improving the structural stability of the bidirectional filter 2. Furthermore, the support columns 22, located within the planting soil, can increase the porosity and permeability of the planting soil. Further, several support members are provided between the outer bottom wall of the bidirectional filter 2 and the inner bottom wall of the frame 1. In this embodiment, the support members are support strips that overlap vertically with the first and second structural reinforcing strips, providing support for the bidirectional filter 2.

[0037] Specifically, the working principle and process of this utility model are as follows: When constructing the planting bed, the construction workers first transfer the modular components to a suitable construction location on the roof. Then, they assemble the frame 1 and the two-way filter 2 into a combined unit. According to the greening requirements of the area, multiple units are placed in suitable positions and connected by connecting rings 4. Next, the drainage holes 11 on the side of the frame 1 that are not adjacent to other frames 1 are sealed with sealing plugs 5, and the adjacent frames 1 are connected by cross clips 8. Finally, the cover plate 3 is installed to complete the construction of the entire planting bed.

[0038] In terms of construction and safety, construction workers only need to assemble modular components, making the process simpler and allowing ordinary construction workers to complete the assembly work with low professional technical requirements. During construction, there is no need for professional construction operations such as surveying, nor is it necessary to build multiple functionally different layers sequentially. After assembly, the planting beds and the roof are independent of each other, and it is not likely to cause safety hazards to the roof.

[0039] In terms of water resource utilization and irrigation systems, water storage, drainage, and irrigation can be achieved through the water supply and drainage channels 12, thus improving the utilization rate of rainwater and reducing water consumption. Furthermore, rainwater and irrigation water can be evenly distributed within each frame 1 through the water supply and drainage through-holes 11, eliminating the need for additional complex irrigation equipment to achieve uniform irrigation, which is beneficial for ensuring normal growth and overall landscape effect.

[0040] In terms of landscape effect and functionality, the problem of water resource constraints has been solved, thus allowing for the selection of more non-drought-resistant plants, increasing plant species, and enriching the landscape layers.

[0041] In terms of thermal insulation and maintenance, the cavity formed between the bottom surface of the frame 1 and the top surface of the roof, as well as the water supply and drainage channels 12, can all play a role in thermal insulation. Furthermore, relevant personnel can easily observe whether there are any structural hazards in the roof through the cavity formed between the bottom surface of the frame 1 and the top surface of the roof, and it is also easy to dismantle the planting beds to repair any structural hazards. During the dismantling of the planting beds, no secondary damage will be caused to the original roof structure, which is far superior to the layered planting bed process.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
