Description

Technical Field

[0001] The present invention relates to the technical field of green buildings, and in particular to a greening module, a greening system and a construction method suitable for greening a slope roof module. Background Art

[0002] In the context of high-density urban development, public green space is gradually showing a three-dimensional development trend. As an important place for social activities, green roofs not only have ecological functions such as regulating air and improving the environment, but also meet people's needs for gathering, catering, entertainment and urban beautification. However, with the advancement of ecological civilization construction and the rapid development of urban construction, high-level and high-density architectural styles have led to a relative reduction in the green space required by urban residents, and urban green space cannot meet the needs of citizens. Therefore, how to use the top of the building, expand the green space, increase the area of ​​urban green space, and improve the urban ecological environment has become a new challenge facing gardeners and builders.

[0003] Modular greening design has a high degree of standardization and industrial production precision, is easy and fast to construct, can save building materials and reduce construction pollution, and is easy to maintain in the later stage. However, the slopes of urban house roofs are different. Traditional modular greening requires adjusting the assembly angle of each module according to the roof slope. The process is cumbersome and cannot meet the current urban greening needs. Therefore, it is necessary to propose an effective construction process to reduce the impact of roof slope on greening modules, thereby effectively improving the construction suitability rate of urban roof greening.

[0004] Chinese invention patent CN202110696818.1 discloses a method for evaluating the suitability of building roof greening based on urban element data. This method first uses urban spatial element data obtained from high-resolution remote sensing images, then constructs a roof greening suitability index system, and then obtains a building roof index information table through quantitative calculation of the suitability of urban building roof greening, and finally completes the evaluation and grading of the suitability of building roof greening. Although this method can intuitively and accurately observe the characteristics of urban roofs and provide a comprehensive reference for the evaluation of the suitability of roof greening, its observation equipment is expensive, the analysis method is complex, the evaluation cost is high, and the urban greening rate can only be increased by expanding the number of suitable roofs.

[0005] Chinese invention patent CN202110374766.6 discloses a triangular box structure for land greening rate. The device is connected by two main boxes through a fixing device. The main box and the ground form an equilateral triangle. The bottom of the box is parallel to the ground. Then, it is equipped with a drip irrigation structure to form a movable green plant box. The box will not produce ground runoff and can keep the substrate layer in a good state suitable for plant growth for a long time. The portability of the device can effectively reduce the construction cost of roof module greening, but it is not suitable for sloping roofs and cannot effectively improve the suitability of roof greening.

[0006] Chinese invention patent CN201811098031.X discloses a slope roof greening system, which includes a roof structure layer, a waterproof root barrier layer, a water storage and drainage layer, a vegetation structure layer, a matrix layer, a water collection and drainage system, etc. Each layer of the structure is inclined, and the retaining ditch wall can prevent matrix laminar flow. The device is suitable for slope roof greening and can effectively improve the suitability of slope roof greening. However, the integrated greening system has the disadvantages of high maintenance cost and difficulty in disassembly and maintenance.

[0007] At present, domestic roof greening has the disadvantages of difficult construction due to various roof slopes and high maintenance costs. The present invention, with the help of a slope roof module greening device and a construction method, can achieve modular greening of inclined roofs. The device has low manufacturing cost, high installation efficiency, and a simple and easy construction method. Summary of the invention

Since the roof has different slopes, the connection method can be selected according to the drainage angle of the roof. The male port 2 connection port is placed at the bottom. The modules can be connected through the water tank connection port, the plug-in structure and the module-to-module connector 10. The female port 3 of the water tank connection port can be closed with a lid when there is more rain or irrigation to prevent too much rainwater from entering the container. A groove 8 is provided at the bottom of the module container 1. Inside the groove 8, the module container 1 is connected to the keel 6, and the keel 6 is connected to the pre-buried steel bars 7 on the roof.
