How to build a vegetable greenhouse, how to build a vegetable greenhouse

1. Bamboo and wood greenhouse standards:

A greenhouse with a width of 6 meters, a length of 30 meters, a top height of meters, a shoulder height of meters, and a distance between arches is a standard greenhouse. A standard greenhouse, covering an area of 180 square meters, is equal to acres of land.

Second, the materials and dosage of building a standard greenhouse:

1. Timber for the neutral column: 16 small cedar trees with long meters; Then choose 30 meters of straight bamboo or small cedar trees as the top beam. Side column materials:

50 small wooden stakes in length. In addition, small cedar trees with a diameter of 5-6 cm are selected to be connected into a 30-meter-long three-meter-long two-row, a total of 60 meters, for shoulder stalls. 2. 600 kg of bamboo material, cut into 102 bamboo pieces 4 cm wide and meter long, for arch rods; In addition, 4 cm wide bamboo pieces are connected into 4 pieces of 30 meters long, a total of 120 meters long, which is used to fix the pole distance and strengthen the arch rod; 3. Materials used for door frames at both ends:

There are about 10 small cedar trees about a meter long. 4. Multi-functional film or non-dripping film (6 filament thickness) 17 kg, skirt film 6 kg. 5. 300 meters of laminating line, several catties of iron wire and nails.

3. Relevant precautions:

1. The side height of the greenhouse is about one meter, and the side height should not be too low, otherwise it is not conducive to the operation and management of the shed. The length can be determined according to the foundation, the larger the greenhouse, the better the thermal insulation performance. However, it should be noted that different crops cannot be planted in the same greenhouse (if you want to grow two crops, 50 meters long can be divided into two greenhouses).

2. The roof film and skirt film of the greenhouse must be covered separately, and the film cannot be used to the end, which is not conducive to ventilation. Usually three laminations are used, i.e., one ceiling film and two skirt films on the left and right sides. The ceiling film is wide meters, the skirt film is wide meters, first install the skirt film on both sides, and then cover the top film, tie the rope at both ends, between each arch, press the film line (belt), overlap 20-30 cm at the junction of the top film and the skirt film, press the top film outside the skirt film, the skirt film landing part should be sealed with soil, and the windless weather should be selected when the greenhouse film is covered, so as not to blow the wind, which is not conducive to covering the film or tearing the shed film.

To build a vegetable greenhouse, you need to prepare enough plastic film and steel frames, first level the ground, then build the steel frame, and finally spread the film.

When building a vegetable greenhouse, we should pay attention to the choice of material, generally when building a bamboo greenhouse, the bamboo should be bent into an arch, and the two ends should be inserted into the thick soil, and then covered with plastic film.

1. Bamboo and wood structure

When building a vegetable greenhouse with bamboo and wood structure, the number of bamboos should first be determined according to the land area, generally one meter between every two bamboos, after the bamboo is ready, it can be sharpened at both ends, and then inserted into both sides of the land at the same time, so that the bamboo is bent into an arch, and finally covered with plastic thin above the bamboo, and covered with plastic film that reaches the ground with soil.

2. Cement structure

When building a vegetable greenhouse with a cement structure, the concrete should be loaded into the arched mold, and after the concrete is dried, the arch bracket will be completed, and then the two ends of the arch bracket will be buried on both sides of the field respectively to make it stand upright, and finally covered with plastic film.

3. Steel structure greenhouse

When building a steel greenhouse, the steel pipe should be welded into an arch using electric welding technology, then inserted into both sides of the soil, buried and fixed with soil, and finally covered with a film on the built support. Moreover, the steel structure greenhouse is relatively firm and has a long service life.

4. Precautions

After the greenhouse is built, the waste materials in the field should be cleaned up, so as not to affect the growth of vegetables, and the firmness of the greenhouse should be checked once to avoid falling apart in the process of use, resulting in the death of vegetables and affecting the yield.

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.

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.

1. On-site pay-off, position correction and height difference correction of embedded parts, if it is found that the center position deviation of embedded parts is large, it can be remedied by using iron plate welding widening method, and the column cutting is remedied by large deviation of the height difference position of embedded parts.

2. The connection between the column and the embedded iron plate.

Some iron plates are directly welded on the column, and the adjustment amplitude of the position of this column is very small, and there is a kind of column and the bottom plate that are welded on the spot, and the adjustment amplitude of this column is large, and the proportion of use is more. Because the welding place between the column and the bottom plate in the later stage also needs to be coated with anti-rust paint and poured with a secondary cement pier, there is no need to worry about its anti-corrosion problem.

3. Installation of truss beams.

The truss girder is the main load-bearing beam of the greenhouse, the transverse truss is a truss in the span direction, with a general length of 12 meters, and the longitudinal truss is a truss in the bay direction, with a general length of 8 meters. The truss and the column are connected by high-strength bolts. It should be noted that the transverse truss needs to be installed on the ground before installing the crane wheels and other accessories in advance.

4. Installation of sink bracket and sink.

The sink bracket needs to be pasted with waterproof tape before installation, and then installed on the top of the truss beam and column, and the installation of the gutter needs to pay attention to its slope and waterproofing to avoid affecting the drainage problems in the later stage.

5. Installation of covering materials.

The installation sequence of the covering material is to install the covering material at the top first, and then install the covering material around the perimeter.

1. The first pre-construction preparation: 100 meters of tape measure, construction line, white ash, punching machine, (9 filament po film, skeleton, circlip card slot, insect net, film winder and other greenhouse materials are provided by professional manufacturers - you can consult me).

2. The second part of the rock hall determines the orientation and specifications of the simple greenhouse, with a length of 80 meters from north to south and a width of 8 meters from east to west. The plot should be convenient for irrigation, free of pollution, flash floods, mudslides, hail, and lightning strikes.

3. The third pay-off: a spacing of 1 meter, release the position of the arch pipe, and dig 40 cm with a punching machine.

4. The fourth installs the arch pipe, the fifth installs the thick or transverse pull and the circlip card slot, the sixth installs the insect net, the seventh film and the film roller, and the eighth makes the shed head and door.

1. Determine the use of multi-story greenhouses.

Before doing the project, we must first consider the location of the area where we are located, the environmental and climatic characteristics, and the use of the glass greenhouse. For example, in the northern region to do planting and seedling glass greenhouse, the most important work is to ensure that the load as much as possible to improve the thermal insulation performance of the greenhouse, we can add an internal insulation system on the top floor of the greenhouse, and try to use double-layer hollow thick glass for the glass around the greenhouse.

Another example is to build a glass greenhouse in the northwest region, we can add a rainwater harvesting system, an external shading system, etc. At the same time, the difference between the planting greenhouse and the ecological restaurant and leisure and sightseeing agriculture is that the height of the internal space is designed, the height of the planting greenhouse can be 4 meters to meters, and the shoulder height of the leisure and sightseeing greenhouse is generally 5 meters to 6 meters.

2. Determine the size of the multi-story greenhouse.

The ridge of the glass greenhouse is generally in the north-south direction, so that the lighting is better. There are also fans and water curtains in glass greenhouses that are generally installed on the end face of the triangular top, so we need to consider the width of this direction, generally about 40 meters to 60 meters. In this way, it can not only ensure the economy, but also take into account the effect of forced cooling and ventilation of the fan water curtain.

3. Selection of glass greenhouse skeleton material specifications and supporting systems.

Any building should consider the economic practicability of its cost, not blindly increase the size of the material. In the northern region, the snow load value of the northeast region and the north China region should be distinguished, and the snow load in the southern region can be appropriately reduced because the snow load is very small or basically non-existent. As for the size of the specific skeleton material specifications, it needs to be designed by a professional greenhouse skeleton manufacturer.

4. Approach construction and construction.

The construction of the foundation, the skeleton construction, the construction of the shading system, the construction of the aluminum profile, the construction of the covering material, the construction of the power distribution system, the installation and commissioning.
