Description

Wide-angle wide roofing composite wall efficient-economical solar-greenhouse

Technical field

The utility model relates to a kind of wide-angle wide roofing composite wall efficient-economical solar-greenhouse, belongs to agricultural heliogreenhouse field.

Background technology

Propose the strategic objective of " improve agriculture equipment level, promote that agricultural development mode changes " in central authorities in 2010 No. 1 file, horticultural crop production facility, livestock breed aquatics scale will be accelerated as a new round " vegetable basket project " constructing emphases.Country 12. five planning outlines " will accelerate development industrialized agriculture " again as the important content advancing structure of agricultural production strategical adjustment and Speeding The Development of Modern Agriculture.

" General Office of the State Council is about planning as a whole to advance in the suggestion of new round the "shopping basket' project suggestion " in 2010 clearly proposes to build a collection of gardening product facility production base.In the gardening product such as In The Suburbs of Large And Medium Cities and veterinary antibiotics advantage producing region, support to build a collection of facility, intensive " vegetable basket " production base ... development gardening product and animal products standardized production.

Packet header municipal Party committee, municipal government's proposition " southern dish north potato, newborn meat develop simultaneously " strategy of agricultural development; planning greatly develops vegetables industry in Daqunshan Mountains areas to the south; emphasis is that development vegetable at protected field is produced; ended for the end of the year 2013; Baotou protected area develops into 13.5 ten thousand mu, and wherein chamber facility area reaches 100,000 mu.

But the greenhouse structure built of each villages and small towns, enterprise is random large in recent years, and drawback is many.It is too small that ubiquity rear roofing, even without male offspring roof greenhouse; Greenhouse wall body is excessively thin, and is not incubated, does not resist cold, or body of wall blocked up, reach 3-5 meters and floor space is excessive; Very little, key light face angle is less than 30 ° to bow member face arch angle, has a strong impact on the photothermal conversion efficiency in light-inletting quantity and greenhouse.In a word, the defect that existing greenhouse exists jointly is:

Back wall is high, face arch master enters that angle little, rear roofing in light face is too short, radiating surface is large, photothermal deformation rate is low, construction cost is high, and some greenhouses mu construction cost reaches 30 ~ 450,000 yuan.

Summary of the invention

The purpose of this utility model be to provide face arch master enter light face angle rationally, back wall compared with short, radiating surface is little, photothermal deformation rate is high, construction cost is low, is applicable to the wide-angle wide roofing composite wall efficient-economical solar-greenhouse of China Western Area and the regional use of north latitude 39 ° ~ 41 °.

The purpose of this utility model is achieved in the following ways:

The utility model comprises bow member, rear roofing, Hou Qiang, it is characterized in that: bow member is truss structure, its leading flank is that semicircular sector, trailing flank are for facing directly, rear roofing is made up of GRC plate, rear roofing is laid on the trailing flank of bow member, and rear wall pastes styrofoam outward by cob wall meta folder styrofoam or brick wall and forms; Bow member face arch base angle angle is 70 ° ± 5 °, 40 ° ~ 45 °, the rear roofing elevation angle, backhouse face width degree 3.2 ~ 3.5 meters, and the lower end of bow member trailing flank is connected to Hou Qiang top; Rear wall height is 2.2 ~ 2.4m, and rear wall thickness of wall body is between 0.5 ~ 1.2 m, and wherein the thickness of styrofoam is between 0.1 ~ 0.15.

The utility model has the advantages that: enter optical property good, key light face, greenhouse angle is greater than 30 °, and four seasons light-inletting quantity is large, and photothermal conversion rate is high.In addition, behind greenhouse, to press down angle large for roofing, and Winter Solstice, sunshine can roofing after direct projection, and the Summer Solstice, sunshine can expose to Hou Qiang base angle; Good heat insulating, rear roofing is vertical with rear wall, and apart from being 2.2 ~ 2.4m, widen 1 ~ 1.2 meter than BTDJ III type, IV type greenhouse, rear roofing outside width widens 1.5 ~ 2 times, and insulation face is large, radiating surface is little, improves heat-insulating property; Cold protective performance is good, and because rear roofing lengthens and face arch arching face length reduction, heat dissipation interface reduces, and improves cold-proof heat insulation performance; Thermal efficiency is high, and increase because rear wall of greenhouse height reduction and rear roofing press down angle, greenhouse volume reducing, effectively increases the thermal energy of unit volume; Reduce construction cost and operating cost, nearly one times of rear wall height reduction, mu body of wall reduces construction cost nearly 50%, and because rear roofing is widened, the film of minimizing 20% and heat-preservation cotton are by consumption.In addition, photothermal deformation rate is high, will effectively reduce heating and administrative expenses of greenhouse; Be suitable for mechanized farming, greenhouse space is large, is provided with farm machinery and imports and exports, be conducive to mechanized farming; Greenhouse is applied widely, except vegetable growing, is also suitable for three-dimensional vegetable, anti-season fruit growing etc.
