As shown in Fig. 1 and Fig. 2, the bridge-type setback building 2 is composed of two floors straight up and down on both sides of the city road 1 and an eleven-story floor with a setback structure arranged above the straight up and down floors; The floors of the setback structure gradually increase in depth on the side of the road until the top floor of the setback building covers the space above the road. The slope formed between the setbacks of the two floors of the bridge-style setback building is preferably 45°; When planning the purpose layout of each bridge-type setback building 2, commercial and parking spaces should be arranged on the first and second floors, and office and residential spaces should be used on the third floor and above; the orientation of the residence and office is facing the setback and facing away from the setback. The road is designed to meet the requirements of lighting and ventilation, and at the same time, it is convenient for people to rest at the retreat.

The above-mentioned integrated scheme of commercial buildings and residential buildings can effectively disperse the flow of people and vehicles in the city, and at the same time solve the problem of temporary/long-term parking of vehicles. Among them, if the volume ratio of the open space where the setback building is constructed is relatively high, the top floor of the setback building can be bridged, that is, the top floor of the setback building completely covers the space above the road, and then the space above the setback building continues to be added. Cover floors. The added floor can be a traditional straight-up and straight-down floor or other floors with special structures.

As shown in Figure 3, the setback space on each floor of the bridge-style setback building 2 is divided into a traffic passage area and a green coverage area 3; specifically:

The traffic passage area includes at least one oblique passage 4 starting from the starting layer of the platform and ending at the terminal layer of the platform and a pedestrian corridor 5 laid on the platform on each floor; The length is 126m, so the planned traffic passage area on the setback building includes two inclined passages 4, the distance between the two inclined passages 4 is 60m, and the width of each inclined passage 4 is 6m; An elevator shaft or a stepped pedestrian passage with an elevator device is installed in the passageway 4;

The green coverage area 3 and the roof of the building are covered with green bodies, and the green bodies include horizontal green bodies and vertical green bodies. Specifically, the width of each floor of the stepped-back building is 4.5m, in which the horizontal green body is set inside the setback, the vertical green body is set adjacent to the edge of the setback, and there is a width between the horizontal green body and the vertical green body. 1.2m area, forming a walking corridor;

The green coverage area 3 is planted with different levels of greening bodies according to different storey heights; the horizontal greening bodies can adopt forms such as planting boxes, planting beds, planting grooves or tree barrels. In principle, different greening bodies should include planting layers suitable for plant growth, filter layer, drainage layer, waterproof layer; the thickness of the green body is determined according to the roof load value of each layer; the vertical green body can be in the form of planting wall, frame planting, etc.; wherein, when frame planting is used, the frame length should be maintained at the same The heights of the corresponding floors are consistent. Therefore, for the vertical green body coverage of the setback in the setback building, it is advisable to use a small scaffolding form; because the root of the small scaffolding (near the plant) is 1.2-1.5m high, and the tip height is 1.8m. ~2.2m.

Specifically, on the terraces located on the third and fourth floors, the horizontal green bodies are multiple rows of tree barrels arranged in the green coverage area 3 of the terraces, and various fruit trees are planted in the tree barrels; On the setback, the horizontal green body is the planting tank 8 set in the green coverage area 3 of the setback; the size of the planting tank is 780mm×320mm×240mm, and a layer of 0.1mm thick polyvinyl chloride plastic film is laid on the bottom to prevent soil pests from spreading The plants planted in the planting groove 8 can be selected vegetables and fruits such as tomato and strawberry;

The vertical green body is planted with the planting bracket 6; the planting bracket 6 includes a steel frame and a plurality of beams; the steel frame is composed of a plurality of inverted L-shaped steel pipes, and one end of each inverted L-shaped steel pipe is vertically inserted and fixed on the At the edge of the setback, the other end is fixed on the outer wall surface of the setback on the upper level; specifically, the vertical height of the steel pipe is 3m, the diameter is 20mm, and the horizontal distance between adjacent steel pipes is 1.2m; each Two beams are horizontally set and fixed between the two steel pipes. One beam is 105mm away from the corresponding setback surface, and the other is 140mm away from the corresponding setback surface. For growing vine crops such as cucumbers and melons;

Set the above-mentioned vertical greening body and horizontal greening body on the roof of the building, or adopt the three-dimensional planting method to plant the corresponding greening body, and use the advantage of the large roof space to plant by combining transparent photovoltaics and greenhouses.

A transparent photovoltaic panel assembly 7 is laid on the top of the planting support 6, and a distance of 1 m is left between the end of the photovoltaic panel assembly 7 adjacent to the building and the building, so that the living balcony on the corresponding floor can meet the ventilation and light transmission requirements at the same time; in addition, the corresponding The photovoltaic panel assembly 7 is equipped with a battery box equipped with an energy storage battery and an inverter in the retreat building, and the energy storage battery is connected to the power grid in the building through the inverter to realize the conversion of solar energy into electrical energy and compensation Electricity demand in the building.

Correspondingly, irrigation pipelines and water storage tanks are installed in the green coverage area 3 of the roof and each floor of the platform; a rainwater collection and diversion tank connected with the water storage tank is installed at the edge of the above-mentioned photovoltaic panel assembly, so that Rainwater can be stored in the water storage tank through the rainwater collection diversion tank and used for daily irrigation.

Through the construction of the above-mentioned urban three-dimensional greening system, the road traffic system, the setback building and the different forms of greening bodies covering the buildings together constitute the three-dimensional greening in the site, which increases the greening rate in the site and makes up for the green space occupied by the road.

Example 2

As shown in Figures 4 to 5, it is a plan for the construction of urban three-dimensional greening within the scope of urban land in a certain hot climate in the northern hemisphere.
