Description

building planting facilities

Technical field

This applicable model relates to a technical facility for planting on the roof and outer wall of a building. It mainly uses solar energy deviation angle technology, especially in northern my country where the negative temperature weather lasts for a long time. Heating system technology.

Background technique

A few days ago, my country's roof planting has been rapidly digging up. In February 2004, hosted by the Ministry of Construction of the People's Republic of China, at the "First National Academic Seminar on Building Planting and Greening" held in Shenzhen, Beijing, Chongqing, Guangzhou, Shenzhen and other cities published academic papers; the meeting also invited Germany , Japanese experts introduced roof greening technology. None of these technologies have protection measures for overwintering in cold areas. They just move the green space to the roof and solve the load, waterproof, soil, plant species, drainage and other technologies.

In the data, we also found a report on the "air vegetable garden" in the United States, which is to build an insulated greenhouse with a middle roof, adopt a light steel frame structure, use film glass for the shed surface, and apply micro-drip irrigation technology.

In the American technology, the winter period is long in Northeast China, and the lowest temperature is -40-50℃. Plants in the greenhouse can only rely on the heat of solar radiation and the heat released from the roof to solve the problem of freezing damage. During use, the frame is severely corroded and the maintenance cost is increased.

Contents of the invention

In order to overcome the deficiencies of the above-mentioned technologies, the utility model provides technical facilities for building a greenhouse on the roof of a building and building a planting trough on the outer wall. The roof greenhouse is composed of plastic steel (inner steel and outer plastic) and plastic pipe concrete columns to form a light frame structure. The benzene board is used as the enclosure insulation filling wall, and the shed surface is covered with plastic agricultural film. The shape has two types of arcs: single-slope and double-slope. For non-south-facing buildings, a double-slope arc-shaped greenhouse can be built on the roof, and an automatic roller shutter machine is installed on it to cover the insulation quilt. Depending on the latitude and orientation of the building, the solar azimuth angle technology can be used, that is, 7 degrees to 15 degrees east of south.

The technology of the present invention is realized through the following technical scheme: the building planting facility is composed of a greenhouse built on the roof of the building and a planting tank built on the outer wall, and heating, irrigation, and solar energy facilities are arranged in the greenhouse. Heat system and irrigation water pre-heating device.

There are two sets of heating systems in the greenhouse, one is the electric heating film, the other is the oil or gas furnace device, as well as the irrigation and water preheating device, and the heater is placed in the water storage tank, which is connected with the solar water heater and the micro-drop tube. There is a storage tank underground to collect rainwater and circulate it through the pump for heating water.

The external wall planting trough is uniformly arranged with the cast-in-place floor slab of the building, and leaves drainage holes and overflow holes. Pick out the wall and pour concrete together with the floor.

The beneficial effect of the applicable model is that it is applicable to the whole country and can plant plants on the roof of buildings all the year round, and promotes early maturation and high yield. The planting layer and soil can save a lot of energy costs for cooling and heating for roof insulation, improve the comfort of residents on the top floor, save roof maintenance costs, and prolong the service life of the roof.

After the popularization and application of this applicable new model, the biggest beneficial effect is that the environment and economic and social benefits of the whole society will play a role for a long time, and it is a more realistic and historically significant innovation for solving the contradiction between a large population and little cultivated land in our country. The heat transfer coefficient of the roof with this technological innovation meets the highest energy efficiency standards.

Detailed ways

The single-slope roof greenhouse is a building facing south, and the orientation angle of the greenhouse is adjusted by using the local solar deviation angle technology. The greenhouse is composed of curved plastic steel, bottom frame and plastic pipe concrete columns to form a light frame structure.

The bottom frame is the plastic-steel chassis of the greenhouse, which is a rectangle whose length and width are respectively smaller than the length and width of the roof. Set up some pull joints in the width direction, and set columns on the north, east, and west sides of the bottom frame to fix them with the bottom frame. There are two horizontal plastic pipes between the columns, which are connected to the columns through four-way pipe fittings, and a door is installed on the east and west mountain walls. The outside of the column is made of benzene board as the enclosure and thermal insulation filling wall, and multiple ventilation windows are opened. A plastic-steel beam is set on the upper end of the pillar on the north wall, which is fixed to the arc-shaped frame, the south end of the arc-shaped frame is fixed to the bottom frame, and the top of the gable wall is fixed to the arc-shaped frame. Install solar water heaters, automatic roller blinds and thermal insulation quilts on the beams of the north wall, fix plastic agricultural film on the arc frame, open a few ventilation windows, and still use agricultural film to open them. Cover the outside of the agricultural film with a large grid of nylon rope to prevent typhoons.

There are two sets of devices in the heating system greenhouse: one is the electric heating film installed on the north wall and is connected to the power supply, and the temperature is adjusted by using the power switch and the sub-switch; the other is the mobile fuel (gas) furnace.

The water supply system consists of water storage tanks, water storage tanks, solar water heaters, pipe networks, micro-drip irrigation networks, water pumps, pipelines and power supply connections. The water storage tank is located underground to collect rainwater and treated reclaimed water, and at the same time connect to tap water, which is a backup water source. The greenhouse is equipped with water storage irrigation, connected to the built-in heater, connected to the solar water heater, and closed circulation through the pump. The water in the irrigation can be preheated, and warm irrigation can be implemented through the pipe network on the wall (Figure 3) and the micro-drop irrigation network in the soil (Figure 4), which is beneficial to increase the ground temperature and early maturity of crops;

If you build a non-south double-slope arc (Figure 2) greenhouse, install the arc frame on the column, and the others are the same as above.

The planting trough on the outer wall (Figure 5) is constructed by uniformly laying steel bars with the floor slab of the building floor, setting up the formwork, and reserving drainage holes and overflow holes, and pouring concrete together on the outer wall and the floor slab. The location of the planting trough is generally set on the outer wall with fewer windows. The vertical distance between the two troughs is 2-4 floors. If it is in the south, it can be higher. At the same time, it is better to plant some drooping climbing plants.
