What is the structure of the vegetable greenhouse, and how to build the vegetable greenhouse

It is divided into two kinds of structures: steel frame and bamboo and wood, the steel frame has good lighting, and the heat preservation is stronger than that of bamboo, but the price is high, and the bamboo and wood are much cheaper. The greenhouse is in the east-west direction, 100 meters is the best. Take the steel frame as an example:

The four points are in charge of the upper Xuan. 10 steel bars for the lower Xuan, 6 bars for latte art. 90 cm in the air.

Roller shutter roll and release. Such a greenhouse is generally enough at 35,000 yuan.

Vegetable greenhouses are greenhouses in the more fashionable words now, but there is a difference between greenhouses and greenhouses, and the types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, entertainment greenhouses, etc.; The design of the greenhouse system includes heating system, insulation system, cooling system, ventilation system, control system, irrigation system, etc.;

Greenhouse covering materials include films, PC boards; Inflatable system: inflatable pump, timing controller; Shading system: various accessories of internal and external shading nets and curtain systems; Ventilation system:

axial exhaust fan, circulation fan, windowing motor, windowing rack, film winder; Cooling system: wet curtain (galvanized sheet, aluminum alloy); Heating system: steel round airfoil radiator, hot blast stove; Other:

Clamp slots, circlips, aluminum profiles for greenhouse installation, various accessories for installation, etc.

Including skeletons, covering materials, sunshade systems, wet curtain cooling systems, heating, etc., it is more popular in the north and is the hand-made choice for getting rich in rural areas in the north

Steps to build a vegetable greenhouse:

1. Determine the location of the installation of the collapse letter greenhouse, and determine the number and length of the greenhouse according to the land area and the current situation;

2. After determining the position, pull the fixed line and sprinkle with lime;

3. Punch holes in the lime line according to the predetermined skeleton spacing, and insert greenhouse pipes at the holes on both sides;

4. Connect the two sides of the greenhouse pipe together with the roof connecting pipe;

5. Clamp the top longitudinal rod with a spring card, some of which are three longitudinal rods;

6. Clamp the film card slot with a three-piece set of hardware card pieces;

7. Install the solid rod of the greenhouse and the group acacia wheel, and then install the reinforced pipes at both ends of the greenhouse;

8. Cover the film, tighten the film pressing line, and a vegetable greenhouse will be successfully built.

Pay attention to the brightness: when installing, the spacing between the greenhouse pipes should be parallel and consistent, and the width of the greenhouse door should be able to drive into the micro-tiller.

7. Install the greenhouse reinforcement rod, and install the reinforcement pipes at both ends of the greenhouse;

8. Cover the film, tighten the film pressing line, and a vegetable greenhouse will be successfully built.

Precautions: When installing, the spacing between the locust wheels of the greenhouse pipe should be parallel and consistent, and the width of the greenhouse door should be able to drive into the micro-cultivator.

The latest construction technology of vegetable greenhouses is as follows:

1. Bamboo and wood arch plastic greenhouse, span 8-14 meters, medium height meter, length of about 50 meters, with a diameter of 3-6 cm bamboo pole as arch, each row of arch rods is supported by 4-6 pillars, arch poles are spaced at a distance of meters, columns are made of cement poles or wooden poles, and columns are spaced between centimeters.

2. Small shed: mainly use thin bamboo poles or bamboo chips, wattles, 6-8 cm steel bars, etc. as support materials, bent into an arched skeleton, medium height cm, span 2-3 cm, insert the frame every 60 cm, the depth is about 20-30 cm, the length depends on the terrain, and the skeleton is covered with plastic film.

3. Shed type and height span ratio: mainly related to the stability of the greenhouse. Under a certain wind speed, the streamlined shed surface has a large curvature, weakened wind speed, and good wind resistance. The high span ratio of the shoulder strap greenhouse is small, the arc is small, and the wind resistance is poor, and the high span ratio of the southern greenhouse is the best.

4. Specifications and direction of greenhouses: greenhouses in the south are generally 30-50 meters long and 6-12 meters wide. The temperature difference between the two ends is too long, and the transportation management is not convenient.

Poor ventilation is too wide, which will also increase the difficulty of design and construction. The higher the greenhouse, the greater the wind load, the lower the greenhouse, the smaller the arc of the shed, which is easy to be damaged by the wind, and the water pocket will be formed when it rains, causing collapse.

5. Site selection and planning: The place of the greenhouse should be sunny, sheltered, flat terrain, fertile soil, good soil quality, sufficient water source, convenient irrigation, and no tall trees and buildings around to shade. When building a large group of greenhouses, the distance between the sheds should be kept in meters, and the distance between the sheds should be kept 5-6 meters, which is conducive to ventilation and transportation.

6. Cover film: it is best to use non-drip film, the width is selected according to the span of the shed, first from both sides, and then covered in turn, the connecting seams of the two films overlap each other by 20 cm, and a film pressing rod is set between the two rods on the shed film, and the film is pressed to make the shed surface into a mutual prism.

7. Install arch rods and tie rods: The tie rods are made of duck egg bamboo, which are fixed at a distance below the top of the column, so that each row of longitudinal columns is formed as a whole. The arch rod is fixed to the top of the column with duck egg bamboo and tightened with iron wire.

Vegetable greenhouses

The vegetable greenhouse is a frame laminated structure with excellent thermal insulation performance, which makes it possible for people to eat out-of-season vegetables. Generally, vegetable greenhouses use bamboo structure or steel structure skeleton, which is covered with one or more layers of thermal insulation plastic film, so as to form a greenhouse space.

1. No matter what the design is, there must be a plan first, of course, we build a fierce and filial piety vegetable greenhouse, we must first plan what kind of output we want to achieve, and then how many acres of land need to be planned, when these preparations are done, we can buy the necessary materials for the construction of the greenhouse according to the specific needs. When the above preparations are made, you can start to build a vegetable greenhouse: according to the specific planning (for example, we build a north-south direction, conducive to ventilation, a width of 5 meters, a length of 30 meters of a vegetable greenhouse) to build steel, in which the distance between the construction of steel can not be too far, generally we choose a distance of 2 meters to build a steel, and the middle of the transverse also needs to build a steel pipe about each meter as a support.

2. In fact, the key work of building a vegetable greenhouse is to build a steel frame, we follow the first step above to build, is to fix these steel frames, here I suggest using the conversion head and wire screwing, in addition to the processing of the wire head must be careful to prevent scratches or plastic sheets, and when binding these fixed steel pipes, it is best to use the triangle binding method, because we know that the triangle has stability, In the process of our use, it can resist the pressure of a certain number of acres or some harsh climate outside.

3. The last step also needs to be careful and careful, that is, to cover the shed film (here we use plastic sheeting), first we need to put the plastic sheet on both sides, and then dig a ditch about a meter on both sides, bury the plastic sheet stretched out on both sides to fix the shed film, and set up a shed anchor every six to eight meters to prevent the wind from causing damage to the shed film. After doing the above steps, the vegetable greenhouse has been basically built, and finally the door is installed at both ends.
