Two, heat-insulating property

Greenhouse daylighting on daytime store heat, this limited amount temperature can store the insulation measure how long decisive factor is the greenhouse in the greenhouse.The greenhouse large tracts of land is independent in the very big space of the temperature difference, the insulation problem is the breach of chamber planting problem, so sun-roof monolateral bilateral retracting lighting film greenhouse is the heat preserving and supplying shed top surface fixedly, the insulation problem handled in absolute construction, the ceiling gross area is fixed multi-level insulation material and is had multiple heat-insulating property species, reach airtight, airtight, light tight, the insulation of hierarchical space temperature, prolong the greenhouse temperature condition to greatest extent, cooperate the attached little space heating greenhouse heat-insulating tunicle that helps solar heating to store the hydro-thermal amount under the heat-insulation layer again, has gross area secondary heat-retaining condition again, heat insulating capsule can also cooperate the heating supplemental heat source under the temperature low condition, being " little " heating control " greatly " area greenhouse temperature condition, is that the greenhouse has reliable thermal insulation foundation.

Three, structural behaviour

Chamber planting is the planting conditions of " transforming nature ", is the autonomous plantation basis of grasping of people's sovereignty control.The design and construction greenhouse is the construction of a combination property mechanism, daylighting condition, heat-insulating property, plant growing height, personnel's mechanically actuated space, and all technical mathematicses have concentrated on the structural behaviour of greenhouse construction.Sun-roof monolateral bilateral retracting lighting film greenhouse is the heat preserving and supplying shed top surface fixedly, independent design daylighting condition; Independent design insulation measure; The operation feasible degree in independent design greenhouse self; Gross area fixedly insulation construction is concentrated all performances that can be incubated, utilize sun-roof automatic hub cap flexibility, alleviated operation easier, solved a difficult problem that exists in the greenhouse lighting process, in design greenhouse transformation space in evening on daytime height, considering plant low coverage in evening insulation benefit, the processing of details on these performances has embodied " sun-roof " structural advantage.

Four, the company's planting greenhouse that designs to the peasant

Plant husbandry is that peasant, scientific farming are that peasant, greenhouse should be the peasants.Designing the greenhouse to the peasant is not single greenhouse performance issue just, is a comprehensive adjustment.At the sun-roof monolateral bilateral retracting lighting film greenhouse of design fixedly during the heat preserving and supplying shed top surface, utilize this performance structure can build a kind of company's planting greenhouse of simple and easy small investment, utilize the high field bund in embanked field to connect, the whole area in embanked field is done skylight sash, utilize this bamboo mounting material, the multi-level plastics class of bedding, not water funk, can seal, airtight, light tight, gross area covering, people can easily start the plane, greenhouse.Fixing this frame plane north does not slide and can rotate, the both sides of framework south edge and field bund face fixing lighting film width, draw simultaneously press from both sides the film line windproof and control start the height, daylighting film and film-pressing line height are that the frame insulating face is along about 45 ° of setting sun light, start fixing lighting daytime, personnel enter interior operational administrative, build insulation during no sunlight, the plane field bund people can walk about, to the draining of canopy face, cleaning accumulated snow is provided convenience, and the plane covers capability of anti-wind in addition, even a planting greenhouse is very simple to build field bund like this, do not destroy ground area construction, can regain and re-use winter, have the greenhouse heat-insulating performance.The steelframe buckle side is also spent seldom, meets peasant's investment condition, construction condition, plantation management condition.

Five, environmental protection and public nuisance free plantation basis

Sun-roof monolateral bilateral retracting lighting film greenhouse is the heat preserving and supplying shed top surface fixedly, and the plane is insulation material fixedly, but the old horticultural covering film of expense and have the colored plastic class all right, and repeating just has heat insulation effect more than the tri-layer.The construction of standard greenhouse can be with meeting the heat-insulating property material product.So the old daylighting film in greenhouse there is permanent service condition, promptly increases heat-insulating property, also reduced the waste of horticultural covering film.Non-polluted planting mainly shows on the greenhouse structure.Can adjust the flexible active of daylighting face control temperature, when daytime, natural temperature was fit to, can remove fixedly fly net of daylighting face, can also cover the canopy insulation evening, be that temperature balance in the greenhouse has the insect protected condition again, established the non-polluted planting basis and possessed the non-polluted planting condition.

Six, canopy face in polymorphic type greenhouse is installed

Sun-roof monolateral bilateral retracting lighting film greenhouse is the heat preserving and supplying shed top surface fixedly, be a kind of rising of attached-greenhouse canopy face and force down that the space ensures the daylighting membrane area in the greenhouse, so in the shed top surface use is installed, should consider the plantation plant height in the greenhouse of building, more rational plant apical side height insulation more has the greenhouse heat-insulating effect, as hothouse plants growth 2m height, selecting bilateral retracting lighting film single-ridgepole glasshouse span is 4m, single window frame central shaft rotates up and down about two length of sides difference of semicircle 1.6m, and central shaft ground strut height is 3.6m.If plantation plant height below 1 meter, the central shaft height is 2.6m.Minimum can also 1.6m height, be 1.6 meters of greenhouse inner heights during flat heat-preserving in evening, during daytime daylighting, the high 3.2m in sunny slope limit carries on the back the following field bund in positive base.Greenhouse construction on the low side also can bring management to go up convenient and temperature condition.In building single big or small process of greenhouse span, not that the window frame width is limit, have only the investment construction basic skeleton to decide, the big change basic skeleton structure that needs of single-ridgepole glasshouse span, with single the many window constructions of end face, can fold or monolaterally fold respectively combination construction with bilateral, resemble the leeward daylighting on the sunny side of combined solar plane skylight during greenhouse lighting, so, single multi-window is because of many window frames increase structures, increase cost of investment, the greenhouse construction of adapt to construction large span, high spatial, control automatically, automated control technology is high.
