Description
Technical field
The utility model relates to agriculture field, is specially a kind of large span and survives the winter a few word steel arch of formula activity inner membrance canopy.
Background technology
Existing plastic canopy is divided into two classes: a class is canopy in spring and autumn; Another kind of is that multimode covers canopy of surviving the winter.
Spring and autumn, plastic tunnel can only make the crop of cultivation shift to an earlier date listing in 15 to 20 days spring, and postpone listing in 15 to 20 days autumn, though benefit is higher than field planting, compared with planting benefit of surviving the winter, there is a big difference.
Though multimode plastic covering booth can be survived the winter, light transmittance is too low, and long-term cropping kind is only for crops such as strawberries; Multimode covers, and operation is wasted time and energy, and strengthens production cost.
Utility model content
For solving the problems of the technologies described above, the utility model will provide a kind of large span to survive the winter a few word steel arch of formula activity inner membrance canopy, and its span is large, and good heat insulating, welding is corrosion-resistant.
The technical solution of the utility model is: a kind of large span is survived the winter a few word steel arch of formula activity inner membrance canopy, comprise bow member, the shape of cross section of described bow member is semicircle, it is characterized in that: described bow member is bolted by arc " several " the word steel of several symmetrical settings and forms, the top of described bow member is provided with steel plate, the inner surface of bow member is horizontally arranged with several horizontal trombone slides, bow member plan vertical is provided with several columns touched with ground, bow member is provided with thermal insulation quilt, ventilate under thermal insulation quilt being symmetrically arranged with one group ventilate film-coiling device and one group film-coiling device, interior bow member is provided with in described bow member, interior bow member is provided with inner membrance, the manual film-coiling device of inner membrance is provided with between interior bow member and bow member.
The manual film-coiling device of described inner membrance is symmetrically arranged with two.
It is 18m-20m that described bow member obtains length.
Distance between described adjacent upright posts is 4m.
Compared with prior art, advantage of the present utility model is as follows:
1, span is large, and the two-sided span of more than 70 word steel arch-shelf can reach 18 meters to 20 meters, and the interior space is large, good heat insulating, and mechanical work is convenient.
2, a few word steel arch-shelf of galvanizing and accessory, bolt connects, no-welding-spot, corrosion resistant.
3, movable inner membrance, electric curl-up film device volume paving, night covering and heat insulating, fine daytime day is rolled and is beneficial to ventilation and lighting.
4, thermal insulation quilt cover, electric screen robling machine volume paving, night and snowy day heat-insulating property reliable.
accompanying drawing illustrates:
Fig. 1 the utility model structural representation;
1-bow member, 2-interior bow member, 3-horizontal trombone slide, 4-column, 5-steel plate, 6-thermal insulation quilt, 7-above ventilate film-coiling device, 8-under to ventilate film-coiling device, the manual film-coiling device of 9-inner membrance.
embodiment:
A kind of large span is survived the winter a few word steel arch of formula activity inner membrance canopy, comprises bow member 1, described bow member 1 length be 18m-20m, the shape of cross section of described bow member 1 is semicircle, described bow member 1 is bolted by arc " several " the word steel of several symmetrical settings and forms, the top of described bow member 1 is provided with steel plate 5, the inner surface of bow member 1 is horizontally arranged with several horizontal trombone slides 3, bow member 1 plan vertical is provided with the column 4 touched with ground, bow member 1 is provided with thermal insulation quilt 6, ventilate under thermal insulation quilt being symmetrically arranged with one group ventilate film-coiling device 7 and one group film-coiling device 8, interior bow member 2 is provided with in described bow member 1, interior bow member 2 is provided with inner membrance, the manual film-coiling device 9 of inner membrance is provided with between interior bow member 2 and bow member 1, the manual film-coiling device 9 of described inner membrance is symmetrically arranged with two.
The utility model bow member is galvanizing 70 " several " word steel (height 70mm, thickness 2mm, top width 50mm) bow member, and bolt connects, corrosion resistant, and intensity is large, and span can reach 18 to 20 meters.Interior membrane support is hot galvanized steel pipe.Horizontal trombone slide is the horizontal trombone slide of galvanizing, laterally link " several " word steel arch-shelf and interior membrane support.Column is the zinc-plated quarter bend detached column of intermediate heat, 4 meters of spacing, strengthens bow member intensity, opposing vertical pressure.For safety tread, the top that easy access operates in bow member is provided with steel plate.Thermal insulation quilt is that in outer film felt, silk floss is rainproof, according to winter minimum temperature adjustment thermal insulation quilt thickness, guarantees that crop safety is survived the winter.Adventitia lower airway film-coiling device, air port is equipped with fly net, temperature is high, high humidity time by upper and lower convection current, timely ventilation drying cooling, increases CO concentration.The manual film-coiling device of inner membrance is used for night or the overlay film insulation of sombre sky, and the daytime that illumination is good rolls up film daylighting, increases illumination.
Utility model works process: roll thermal insulation quilt and inner membrance daytime, makes crop fully accept irradiation and the ventilation of sunlight, increases CO
