Aluminum profile on top of agricultural glass greenhouse
The all-glass greenhouse refers to the intelligent multi-span greenhouse covered with a single layer of tempered glass on the top. It is the strongest structure, the most complete system, and the most expensive type of greenhouse in the field of modern facility agriculture. What are the advantages and disadvantages of the all-glass greenhouse, and what model does the aluminum profile on the top have?
The advantages and disadvantages of all-glass greenhouses
The advantages of the all-glass greenhouse are the high light transmittance of glass, the highest light transmittance of treated glass is as high as 97%, and the glass has a long service life, and the light transmittance will not decrease over time. This point is sunlight. The board and film are incomparable, followed by strong structure, strong wind and snow resistance, and high degree of mechanization.
The disadvantage of glass greenhouses is that compared with traditional solar greenhouses used in northern regions in winter, they need to be heated and consume more energy in winter. This has little effect in the southern region. Secondly, the initial investment is expensive.
The composition of the aluminum profile on the top of the all-glass greenhouse
The top of the all-glass greenhouse is made of aluminum profiles from above the truss beams. The difference between high-end greenhouses and ordinary greenhouses is the gutter. The high-end greenhouses use aluminum alloy gutters, and the ordinary greenhouses use iron gutters.
1. Roof ridge: the top spire spans 4 meters, and the gold-shaped roof ridge on the top is used to fix the left and right gable beams.
2. Herringbone beam: Located on the left and right sides of the gold-shaped roof, it is the main material for fixing the glass. The glass is inserted into the groove in the middle of the herringbone, and then sealed with glass glue.
3. Top herringbone beam accessories: herringbone angle plate, inner profile, glass clip, lower part of herringbone connector, upper part of herringbone connector, upper part of roof connector, lower part of roof connector.
Cost of aluminum profile on top of all-glass greenhouse
The price of aluminum profiles at the top of ordinary iron gutters is comparable to that of iron-framed gables. The average price per square meter is 4 US dollars, but the difference is the material specifications of the pillars, trusses, and gutters of the top glass material. The skeleton of the covering material is larger than that of the top sun panel. The weight of 5mm tempered glass is 12.5kg per square meter, and the weight of one square meter of sunshine board is 1.45kg, which is nearly ten times different. In summary, the cost of the all-glass greenhouse is about 5% higher than the cost of the top sunlight plate pattern greenhouse, and the comprehensive cost is 60 to 70 US dollars per square meter.
Standard supporting system for all-glass greenhouse
The standard for all-glass smart greenhouses is hot-dip galvanized fabricated framework materials, electric external shading systems, electric internal shading systems, electric staggered top-opening systems, electric internal insulation systems, dew trough systems, fan water curtain cooling systems, The electric window system outside the water curtain, the Internet of Things control system, and the heating system in the north are also needed (the heating system requires the owner to select an appropriate heat source according to the actual local situation. In many areas, coal-fired boilers have adopted the prohibition method, and some vegetable and flower production areas The water source heat pump, electric heating, air energy and other heating systems are used). In short, with the support of various supporting systems, the all-glass greenhouse is like a natural light plant factory that can provide stable vegetables, flowers, and fruits all year round. Output, while greatly liberating the labor force, it is also a reference template for the upgrading and transformation of greenhouses in traditional planting areas with the aging of growers.
