Technical Field
[0001] This utility model relates to the field of high-rise buildings, specifically to a balcony suitable for planting in high-rise buildings. Background Technology
[0002] In current mainstream urban high-rise building balcony designs, balconies are primarily designed for basic living functions such as drying clothes, providing sunlight, and ventilation, without reserving areas for planting. This leads to a shortage of space for urban balcony planting and greening. Furthermore, the installation of conventional planting facilities on balconies significantly reduces their original living functions, and scattered planting equipment also poses potential safety hazards. Therefore, there is an urgent need to develop a dedicated balcony design for urban high-rise buildings that integrates planting, living functions, and safety features. Summary of the Invention
[0003] The purpose of this utility model is to provide a balcony suitable for planting in high-rise buildings, which consists of an inner balcony 310 and an outer balcony 300, separated by a panoramic floor-to-ceiling window 302 installed on the inner wall 102. The outer balcony 300 is a plant planting area. The outer railing 301 installed on the outer wall 101 has a concave groove 100 formed at the bottom by the balcony base plate 110, the outer wall 101, and the inner wall 102. The bottom and sides of the concave groove 100 are coated with a waterproof layer 103. Drainage and ventilation boxes 500 are installed on the outer wall 101 and the inner wall 102 respectively. A water pipe installation hole 201 is installed on the outer side of the inner wall 102, and a drip irrigation pipe 105 is also installed inside the inner wall 102. Both the water pipe installation hole 201 and the drip irrigation pipe 105 are connected to the drainage system 202 of the inner balcony.
[0004] The concave trench 100 can be filled with soil or water for planting plants; the height of the inner and outer walls of the concave trench 100 and the distance between the walls can be adjusted to form a variable planting depth and planting width; its length is set according to the length of the balcony itself; the soil in the middle of the concave trench can also be equipped with a partition board to plant plants with different soil and water requirements in different sections.
[0005] The outer railing 301 is made of high-strength light-transmitting material and can be half the height of the balcony or the entire height of the balcony, making the balcony semi-open or fully enclosed respectively. The outer railing 301 can be a fixed half height or the entire height, or it can be height-adjustable, which can be adjusted according to the climate, temperature or the needs of planting plants.
[0006] An open panoramic floor-to-ceiling window 302 is installed on the inner wall 102, which together with the outer wall 101 and the outer railing 301 forms a semi-open or enclosed space that allows light to pass through from both the front and back. A supplementary light 400 is installed on the top of the space. The supplementary light 400 can be converted into a supplementary light strip and can be installed on the lower inner edge of the handrail of the outer railing 301 to provide light for the outer balcony 300 or to provide light and heating for the plants.
[0007] Furthermore, the drainage vent box 500 penetrates both the inner wall 102 and the outer wall 101, and the interior of the drainage vent box 500 adopts a layered porous design with a filter layer (see structural schematic diagram). Figure 5 ).
[0008] To ensure safety, all components of the balcony provided by this utility model are fixedly installed.

Detailed Implementation
[0019] In Example 1, as part of the urban high-rise building itself, the plantable balcony of this utility model has been comprehensively considered and constructed during the design and construction of the balcony.
[0020] This embodiment provides a method such as Figure 1 The balcony shown is suitable for planting in high-rise buildings. It consists of an inner balcony 310 and an outer balcony 300, which are separated by a panoramic floor-to-ceiling window 302 installed on the inner wall 102. The outer balcony 300 is a plant planting area, and a supplementary light 400 is installed on the top of the outer balcony to supplement the light on cloudy days or in the evening.
[0021] The outer railing 301 installed on the outer wall 101 is made of high-strength light-transmitting material; the bottom is formed by the balcony base plate 110, the outer wall 101, and the inner wall 102 to form a concave groove 100 (see specific structure). Figure 2 and Figure 3 The bottom and sides of the concave trench 100 are coated with a waterproof layer 103. Soil is laid on top of the waterproof layer 103 inside the concave trench 100. Drainage and ventilation boxes 500 are installed on the outer wall 101 and the inner wall 102 respectively. A water pipe installation hole 201 is installed on the outer side of the inner wall 102. A drip irrigation pipe 105 is also installed inside the inner wall 102. Both the water pipe installation hole 102 and the drip irrigation pipe 105 are connected to the drainage system 202 of the inner balcony.
[0022] Considering that the typical row spacing for field planting is 26.7cm and the typical root activity depth for field crops is 25cm, the recommended dimensions for the concave trench 100 on the balcony in this embodiment are 26.7cm wide and 25cm deep. The advantage of these dimensions is that they meet the minimum planting space required for the outer balcony 300 without affecting the basic living functions of the inner balcony 310. Furthermore, the dimensions of the concave trench 100 can be adjusted by the distance and height between the outer wall 101 and the inner wall 102, satisfying diverse user needs for planting depth and width. Additionally, the length of the concave trench 100 is set according to the length and shape of the balcony itself, referring to… Figure 4 A top view of the cross-section.
[0023] Furthermore, the interior of the drainage vent box 500 adopts a design in which a layered porous structure 501 encloses a filter layer 503. Figure 5 The filter layer 503 can be made of materials such as gauze, activated carbon, or non-woven fabric. It can be replaced at any time via the removable section 502. Large particles of sediment are blocked by the interlayered pores 501 forming the space 505, while small particles of impurities are adsorbed by the filter layer 503, ultimately ensuring that the outflowing water is clean, environmentally friendly, and meets municipal standards. When drainage is not required, the filter layer 503 can be replaced with a sealed layer 504 to prevent water leakage.
[0024] Figure 6 This is a diagram showing the actual usage effect of the balcony in this embodiment.
[0025] Example 2 is a plantable balcony designed for users with diverse planting needs.
[0026] Based on Embodiment 1 above, if a user needs to plant multiple plants with different requirements, a partition plate 106 can be installed inside the concave trench 100 to divide the concave trench 100 into more than one independent part. Each part is connected to the drip irrigation pipe 105 and the drainage and ventilation box 500. Each independent part independently regulates soil moisture conditions to meet the planting needs of different plants. A schematic diagram of the concave trench structure is shown below. Figure 6 .
[0027] Example 3: A plantable balcony designed for aquatic plant cultivation.
[0028] Compared to Example 1, Example 2 involves filling the concave trench 100 with water to create an aquatic environment. The rest of the components are completely identical to Example 1.
[0029] Example 4 is designed for planting in cold regions. Compared to Example 1, Example 3 raises the height of the outer railing 301 made of high-strength, light-transmitting material to the roof to prevent extreme low temperatures in winter in cold regions. The rest is completely identical to Example 1.
[0030] Example 5: A plantable balcony designed specifically for the renovation of old high-rise buildings.
[0031] The fundamental difference from Embodiment 1 is that the inner wall 102 and the panoramic floor-to-ceiling window 302 in Embodiment 4 are added later on the basis of the existing balcony. Considering the load-bearing capacity of older buildings, the inner wall 102 should preferably be made of lightweight building materials. This is also why its concave groove 100 and outer balcony 300 are narrower than those in Embodiments 1-3. Therefore, the top space in this embodiment does not have the conditions to install a supplementary lighting 400; the supplementary lighting 400 is cancelled, and instead, a light strip is installed on the lower inner edge of the outer railing 301. Furthermore, considering that some older buildings' balconies do not have water inlet pipes, the drip irrigation pipe 105 can be omitted.
[0032] Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, additions, or substitutions made by those skilled in the art within the scope of this utility model should be protected by this utility model.
