Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of residential design, and in particular to a sky garden of a fourth-generation residence. Background Art

[0002] Since 2006, the national government has continuously issued documents supporting the development of green buildings. In 2017, the July 1st Forest Garden, China's first "fourth-generation residential" project, was launched in Chengdu. Starting in 2019, the Ministry of Housing and Urban-Rural Development fully recognized the construction of fourth-generation residential buildings and officially released the "Urban Forest Garden Residential Design Standard" in 2021. Subsequently, various regions have introduced and implemented relevant policies, such as increasing the proportion of cantilevered balconies to the total floor area of ​​residential units, relaxing design restrictions on fourth-generation residential units, excluding indoor sky gardens and public green platforms from the building envelope, excluding indoor sky gardens outside the main structure from building spacing and sunlight spacing, and exempting them from prefabricated building requirements. These policies have provided strong support for the development of the industry.

[0003] At present, the structure of extra-long cantilevered terraces in the fourth generation of houses is usually realized by adding diagonal braces, setting columns on the balcony, and raising the cantilever beams. However, the diagonal bracing method requires the building to have supports above the terrace, which makes the facade treatment difficult, the facade is not beautiful, and the construction is relatively difficult. The independent components in the air make the support and formwork construction difficult. The method of setting columns on the balcony makes the facade unsightly, and the relevant policies such as the building area calculation rules in different regions restrict the setting of columns. The method of raising the cantilever beam increases the requirements for the floor height due to the increase in beam height, and the cantilever length is limited. The cantilever beam itself is a statically determinate structure with low structural redundancy. The deflection cracks of the structural calculation beam are uncontrollable, and the structural economy is poor. Therefore, the problems of the cantilevered terrace support method in the existing technology, such as unsightly facade, high construction difficulty, limited length and poor structural economy, need to be solved urgently.

[0056] The embodiment of the utility model provides a sky garden for a fourth-generation residence.

[0057] See also Figure 1 , Figure 1 The structural diagram of the sky garden of the fourth generation residence provided by some embodiments of the present utility model is schematically shown.

[0058] like Figure 1 As shown, the sky garden 1000 of the fourth-generation house includes: a cantilevered terrace 10, a first vertical curved arm 30, a second vertical curved arm 40, a first steel bar 50 and a second steel bar 60.

[0059] The cantilevered terrace 10 is provided on and perpendicular to the structural column 20. A first vertical curved arm 30 is an arc-shaped structure, located below the cantilevered terrace 10 and extending from the structural column 20 to the cantilevered terrace 10. A second vertical curved arm 40 is an arc-shaped structure, located above the cantilevered terrace 10 and extending from the structural column 20 to the cantilevered terrace 10.

[0060] Each of the first and second steel bars 50 and 60 includes a first end, a second end, and a connecting portion. The first end 51 of the first steel bar 50 is positioned within the cantilevered terrace 10, while the second end 52 is positioned within the structural column 20. The connecting portion 53 passes through the first vertical curved armpit 30 to connect the first and second ends 51 and 52. The first end 61 of the second steel bar 60 is positioned within the cantilevered terrace 10, while the second end 62 is positioned within the structural column 20. The connecting portion 63 passes through the second vertical curved armpit 40 to connect the first and second ends 61 and 62.

[0061] The sky garden of the fourth-generation residence provided by the embodiment of the utility model adopts the method of vertical arc-shaped armpit support to cantilever the terrace, which has beautiful facade, low construction difficulty, small limit on the length of the cantilevered terrace, and good structural economy.

[0062] Please continue reading Figure 1 In some possible implementations, in order to make the first vertical arc-shaped armpit 30 and the second vertical arc-shaped armpit 40 more stable, a third steel bar 70 may be added to the first vertical arc-shaped armpit 30 and a fourth steel bar 80 may be added to the second vertical arc-shaped armpit 40 .

[0063] The third and fourth reinforcement bars 70 and 80 each include a first end, a second end, and a connecting portion. The first end 71 of the third reinforcement bar 70 is positioned within the cantilevered terrace 10, while the second end 72 is positioned within the structural column 20. The connecting portion 73 passes through the first vertical curved armpit 30 to connect the first and second ends 71 ​​and 72. The third reinforcement bar 70 and the first reinforcement bar 50 are intersecting. The first end 81 of the fourth reinforcement bar 80 is positioned within the cantilevered terrace 10, while the second end 82 is positioned within the structural column 20. The connecting portion 83 passes through the second vertical curved armpit 40 to connect the first and second ends 81 and 82. The fourth reinforcement bar 80 and the second reinforcement bar 60 are intersecting.

[0064] It should be understood that the arc ranges of the first vertical curved arm 30 and the second vertical curved arm 40 can be determined based on actual engineering design requirements, and the arc ranges of the first vertical curved arm 30 and the second vertical curved arm 40 can be the same or different. The location, quantity, and parameters (e.g., length, cross-sectional area) of the first steel bar 50, the second steel bar 60, the third steel bar 70, and the fourth steel bar 80 can be determined based on the length of the cantilever terrace 10, the arc ranges of the first vertical curved arm 30 and the second vertical curved arm 40, and the embodiments of the present invention do not impose any limitations on this.

[0065] Please also refer to Figure 2 and Figure 3 , Figure 2 and Figure 3 The present invention shows the drainage structure of the sky garden of four generations of houses provided by some embodiments of the present invention.

[0066] like Figure 2 and Figure 3As shown, in some embodiments, the cantilevered terrace 10 is provided with a first groove 11 and a drainage ditch 12. The drainage ditch 12 is a groove structure, and the first groove 11 and the drainage ditch 12 are arranged adjacent to each other. The cantilevered terrace 10 also includes a platform portion 13. A paving portion 14 is provided above the drainage ditch 12 and the platform portion 13. The paving portion 14 covers the drainage ditch 12 and avoids the first groove 11, that is, it does not cover the first groove 11. The paving portion 14 can be made of non-slip bricks, fired bricks, concrete bricks, or permeable bricks, etc., laid above the drainage ditch 12 and the platform portion 13.

[0067] A covering layer 111 and a drainage layer 112 are provided in the first groove 11 . The covering layer 111 is provided above the drainage layer 112 and includes soil required for growing plants. The covering layer 111 is used to grow green plants and flowers. The drainage layer 112 is used to drain water in the first groove 11 .

[0068] In some embodiments, a filter layer 113 and a waterproof layer 114 are further disposed within the first recess 11. The overburden layer 111 is disposed above the filter layer 113, which is disposed above the drainage layer 112, which is disposed above the waterproof layer 114. The filter layer 113 is used to filter solid particles, thereby preventing solid particles in the overburden layer 111 from entering the layer structure below the filter layer 113. The waterproof layer 114 is used to prevent water within the first recess 11 from penetrating downward into the reinforced concrete structure of the cantilevered terrace 10, thereby protecting the cantilevered terrace 10.

[0069] It is easy to understand that the designer may also provide other structural layers within the first groove 11 according to actual needs. For example, an isolation layer may be provided within the first groove 11, with the filter layer 113 provided above the isolation layer, and the isolation layer provided above the drainage layer 112. The isolation layer is used to isolate the roots of plants planted in the cover layer 111 to prevent the roots of the plants from penetrating into the waterproof layer 114.

[0070] A linear drain ditch 15 is provided between the overburden layer 111 and the paving portion 14. The linear drain ditch 15 is recessed downward relative to the paving portion 14, thus separating the overburden layer 111 from the paving portion 14. A notch 141 is provided in the paving portion 14 above the drain ditch 12, allowing water flowing into the linear drain ditch 15 to flow into the drain ditch 12 through the notch 141.

[0071] Drain holes 102 are provided on the common side wall 101 of the first groove 11 and the drainage ditch 12. Optionally, the drainage layer 112 may be a drainage board, and the drainage board and the drainage holes 102 are arranged correspondingly in the horizontal direction, so that water flowing into the drainage layer 112 can flow into the drainage ditch 12 through the drainage holes 102.

[0072] A drain pipe 16 is provided below the platform 13. A side drain 121 is provided on the other sidewall of the gutter 12. The side drain 121 is connected to the drain pipe 16, which is connected to the residence's external drainage system. Water flowing into the gutter 12 flows through the side drain 121 into the drain pipe 16, where it is then discharged to the residence's external drainage system.

[0073] The linear drain ditch 15, located between the pavement 14 and the overburden 111, allows water from the platform 13 to quickly flow through the pavement 14 and converge into the linear drain ditch 15. This reduces the slope distance the water flows and provides a strong water collection capacity, allowing the water from the platform 13 to be quickly drained. Furthermore, the linear drain ditch 15 is aesthetically pleasing and can be customized to achieve various landscape effects. A number of access ports can be spaced at regular intervals along the top of the linear drain ditch 15 to accommodate drainage repair and maintenance needs.

[0074] Water in the overburden layer 111 is filtered through the filter layer 113, seeping down into the drainage layer 112 (typically a drainage board), and then entering the drainage ditch 12 through the drainage holes 102 provided in the common sidewall 101. The drainage board is made of plastic (e.g., polyethylene, polypropylene) or other corrosion-resistant materials, offering excellent durability and drainage capabilities. The surface of the drainage board has a concave-convex structure that forms drainage channels within the board, facilitating water flow while preventing soil or other solid particles from entering the drainage holes 102. This minimizes the impact of moisture on concrete structures, preventing moisture penetration and accumulation, thereby protecting the stability of the concrete structure and extending its service life.

[0075] In some embodiments, there are multiple drainage holes 102 set on the common side wall 101, and the multiple drainage holes 102 are spaced apart at corresponding positions of the drainage board. The bottom surface 123 of the drainage ditch 12 is set at an angle, and the height of the bottom surface 123 gradually decreases from the side close to the drainage hole 102 to the side close to the side drain 121, that is, starting from the side close to the drainage hole 102, the closer to the side drain 121, the lower the height of the bottom surface 123, which is conducive to quickly discharging the water in the drainage ditch 12 to the drain pipe 16 through the side drain 121.

[0076] Optionally, the drain pipe 16 is a straight structure that can quickly drain water. Compared with the method of setting a water seal or a trap, soil particles or debris are not easy to deposit, the water flow rate is fast, and the drainage capacity is strong, which can effectively reduce the situation of pipe blockage.

[0077] Please continue reading Figure 3In some embodiments, the fourth-generation residential sky garden 1000 further includes a first water filter plate 90 and a second water filter plate 91. The first water filter plate 90 is disposed at the bottom of the linear drain ditch 15, and the second water filter plate 91 is disposed at the opening 122 of the drain ditch 12 and covers the opening 122 of the drain ditch 12. The first water filter plate 90 is configured to filter solid particles to prevent solid particles flowing into the linear drain ditch 15 from entering the drain ditch 12 through the gap 141 of the pavement 14. The second water filter plate 91 is configured to further filter solid particles to prevent solid particles flowing into the gap 141 of the pavement 14 from entering the drain ditch 12.

[0078] In summary, the fourth-generation residential sky garden provided by the present invention utilizes vertically curved armpits to support the cantilevered terrace, resulting in a beautiful facade, low construction difficulty, minimal restrictions on the cantilevered terrace length, and excellent structural efficiency. Furthermore, the use of a linear drainage pipe allows for rapid drainage of water, making it less prone to soil particles and debris accumulation than with water seals or traps. The water flows rapidly, providing strong drainage capacity and effectively reducing pipe blockage.

[0079] Those skilled in the art will appreciate that the above-mentioned technical features can be used in any combination without limitation. The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to more clearly understand the technical features, purposes and effects of the present invention and implement them accordingly.
