Infrastructure construction for greenhouse construction

The construction and installation of greenhouse greenhouses should be tailored to local conditions, and the wall materials of greenhouses can be used as long as they have good insulation and heat storage capacity.

It is emphasized here that the interior wall of the greenhouse should have a heat storage function to store heat. At night, this heat will be released to maintain the temperature balance inside the shed. Brick walls, cement plastered walls, and soil walls all have heat storage capacity. The walls of greenhouses generally adopt a brick concrete structure, which is better. The basic design of greenhouses is determined by geological structure and local climate conditions. In cold regions and areas with soft soil, the foundation is relatively deep. Greenhouses that cannot be produced all year round are deeper than greenhouses that are produced all year round. A 20 to 30 centimeter thick ground beam should be added to the foundation filled with rubble or river stones, and walls should be built on top of the ground beam. The walls should have insulation layers, and the insulation layers should be filled with insulation materials such as benzene board and perlite. It is recommended to leave expansion joints for walls exceeding 70 extended meters. The back wall of the greenhouse should have ventilation windows for winter ventilation based on the nature of the greenhouse's use. Before laying and sealing the roof of the rainbow greenhouse wall, the embedded parts of the arch frame should be removed for use during the installation of the arch frame. The height of the greenhouse wall is determined by the span of the greenhouse, and it is generally recommended to cross the back wall of the greenhouse by 8 meters with a height of 2.5 meters. A height of 2.3 meters is recommended for the rear wall of a 7.5 meter greenhouse. The spacing between embedded parts on the greenhouse wall varies depending on the type of greenhouse purchased, with 0.8 meters, 1 meter, and 1.2 meters respectively. For embedded parts Φ T-shaped steel bars with a diameter of 16mm or more, with a height of 25cm and exposed to the wall by 6cm.

Attention: The embedded parts of the arch are buried at a distance of half of the distance between one arch and the inner side of the gable. For example, arches with a distance of 1 meter should be buried at a distance of 0.5 meters, while those with a distance of 1.2 meters should be buried at a distance of 0.6 meters. When installing, use a steel tape measure with a length of more than 50 meters to reduce errors. In addition to embedding the embedded parts of the arch frame, pressure film wire hooks should also be embedded. To facilitate the installation of the pressure film line. The pressure film line hook on the top of the rear wall is available Φ 12 steel bar production, T-shaped steel bar head bent into hooks or rings. The upper part of the 25cm high hook should be exposed to the wall by about 8cm, and the pressure film line hook should be located on the outer side of the arch embedded parts, with a parallel distance of about 5-8cm from the arch embedded parts. The pressure film line hook ring should be installed in the middle of the two embedded parts of the arch frame, one for each gap. A door is left on one side of the gable, and the greenhouse of the workshop needs to be built at one end of the greenhouse. The workshop should not be too high to avoid shading. A 25cm wall skirt should be built at the front and bottom corners of the greenhouse with embedded parts. The main functions of the skirt wall are to prevent wind, water, and fix the arch. The embedded parts of the wall skirt arch frame should correspond to the embedded parts of the rear wall arch frame. The skirt wall also needs to be equipped with pressure film line hooks, which can generally be set on the outer side of the skirt wall. Corresponds to the back wall pressure film line hook. After the installation of the arch frame, the skirt wall and rear wall should be plastered and the welded joints should be plastered inside. When plastering, a sloping surface should be applied outward to facilitate drainage.
