Description
The utility model relates to a kind of plastic film shed, belongs to the improvement of plastic film green house of vegetables.
Plastic film shed for planting vegetable, flowers, grow seedlings and vegetables in improper season provide suitable condition.Present widely used plastic vegetable greenhouse is a shed, the structure of this booth is made up of ground connection vertical rod and arch bar, arch bar is fixed on the ground connection vertical rod or directly is fixed on the ground, at arch bar loam cake plastic film, this plastic tunnel heat-retaining condition is good, but canopy inner area availability is not high, especially lower to its availability of akala greengrocery crop, this structure does not have the setting of ventilation, so gas permeability is poor, especially in semi-tropical area, the green house of vegetables of this structure can utilize the time very short in summer, can only use in the winter time, sometimes the temperature in winter is also higher in the subtropical zone, cause the crop morbidity and influence productivity effect, plastic film on arched frame is difficult to fix in addition, cause and be easy to ponding rainy season, film destructible and roof leaking, make the crop susceptible disease, in addition, the wind loading rating of arched roof structure is poor, in order to overcome above-mentioned shortcoming, the someone designed canopy around the canopy post is arranged, the version that arched frame is supported by the canopy post, as the Chinese patent 95210647.7 disclosed plastic film sheds of growing seedlings, this booth replaces single arched frame with two arched frames, and arched frame is fixed on the canopy post, arched frame loam cake transparent panel, this structure better solves land utilization rate and the printing opacity in the canopy, insulation ventilate and in the problems such as cooling difficulty of high temperature season but still exist, and the transparent panel price that this structure adopted is more expensive, the problem that cost is big.
The purpose of this utility model: provide a kind of have extremely efficient in preserving heat, the gravity-flow ventilation condition is good, can be suitable for planting short living leaf vegetables, can be suitable for planting the rattan melon or fruit type crops again, availability height in the canopy has the stronger defence typhoon and the vegetables plastic film shed of heavy rain ability.
The utility model is by portal-rigid frames, ridge, purlin, rafter, the skylight, linking beam, composition such as montant and basis, portal-rigid frames are fixed on the concrete foundation, the quantity of portal-rigid frames is different and different according to the length of canopy, on two hypotenuse interface points of portal-rigid frames ridge is installed, arrange above it that purlin is as vertical connector, between ridge and the purlin skylight is set, arrange rafter on the purlin, on the column of portal-rigid frames linking beam is installed, montant is installed on linking beam, the roofing covered with plastic film is gone along with sb. to guard him with fly net or plastic film according to the different mining in season around the canopy.
Now be described further in conjunction with the accompanying drawings
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model portal frame structure schematic diagram
The utility model is made up of portal-rigid frames 1, ridge 2, purlin 3, rafter 4, skylight 5, linking beam 6, montant 7, fence gate 8 and concrete foundation 9.Portal-rigid frames 1 are made up of brace 10 and column 11, column 11 is fixed on the concrete foundation 9, article two, an end of brace is fixedlyed connected with column respectively, the other end intersects fixedly connected, two braces of portal-rigid frames intersect the fixed connection place ridge 2 are set, purlin 3 is set as vertical connector on the brace between portal-rigid frames, between ridge and purlin, arrange skylight 5, the one side in skylight is fixed on the ridge 5 by loose-leaf, another side is fixedlyed connected the unlatching of being convenient to the skylight with strut, on purlin, arrange some rafters, rafter stretches out the certain distance of the brace of rigid frame, to form the eaves that hide rain, linking beam 6 is installed on the column of portal-rigid frames, montant 7 is installed on linking beam.In order to strengthen portal-rigid frames intensity, between two hypotenuses of portal-rigid frames, be provided with singletree 13 and fixedly connected with hypotenuse.
In order to strengthen the intensity of big booth structure, in reaching, the end span of booth on the brace of the portal-rigid frames of span and the column wind resistance cable is installed.
Above-mentioned said rafter and montant are to adopt the channel-section steel manufacturing, above plastic film is installed in, by the jump ring in the channel-section steel film are blocked.The fence gate 8 of canopy can be located at the gable portion or the side of canopy.
Be utilization of space in the availability that improves soil in the canopy and the canopy, be beneficial to growth of crops and the ventilation condition in the canopy, that the construction profile of canopy is chosen as is long 42 meters, wide 8 meters, to rise 3.8 meters, column high 2.3 meters, and standoff distance 2-3 rice is comparatively desirable between canopy and the canopy.
The utlity model has good looking appearance, rational in infrastructure, ventilation condition is good, uprising rain wind resistance Ability is strong, and the utilization rate advantages of higher of canopy is suitable for planting leaf, the fruit type vegetable of short life, and is also suitable The plantation of rattan, stem type melon and fruit vegetables should be planted, ventilating problem can be incubated and solved.
