Description

Bidirectional hanging rope plastic greenhouse

The utility model relates to a kind of plastic film shed, and its skeleton is made of the suspension cable of both direction in length and breadth.

Plastic tunnel be that this century, the fifties began to develop with plastic film as obducent protection ground facility, generally adopt the arch form form; The larger area booth is taked a connection mode, and ceiling must be provided with gutter, and shading is more, and span is little, and the post net is close, unfavorable big machinery operation, and influence land use efficient.

The purpose of this utility model is the plastic tunnel that will provide a kind of skeleton to constitute by large span suspended cable structure with both direction in length and breadth, its cover film is directly buckled bundle on the suspension cable skeleton by bundle film band, it is softly tough and tensile to have ceiling, no gutter, center pillar is few, spacious bright, and good wind resistance snow disaster evil ability is arranged.Be applicable to agricultural planting, also can be used for multiple occasions such as amusement, country trade, archaeological excavation, the disaster relief be emergent.

The purpose of this utility model is achieved in that the two-force member that utilizes gentle rope and depression bar one class only to be subjected to two power effects and keep balance, with reference to component forms such as the rafter of conventional house, purlin, beam, posts, respectively two ends are firmly lain in the outstanding rafter of the earth, outstanding purlin and overarm, under the pendulum post that allows to do to swing significantly supports, tighten into the suspension cable skeleton; With going along with sb. to guard him superimposed 5～10 centimetres of the edge of adjacent two width of cloth plastic films that cover usefulness, directly tightly restraint in outstanding rafter formation booth coverage rate from superimposed with bundle film band.The canopy face keeps appropriate tilt, in order to rainwater Channel Group.And can choose the canopy shape of various ways such as Dan Po, backing, arch or multi-paraboloid by different terrain landforms such as Plain, hillock, hillside fields, mountain valleys, build according to gesture.The canopy head of suspension cable plastic tunnel is higher, and the canopy face can extend to ground along the outstanding purlin beyond the canopy end pendulum post, forms the canopy head of inclination, and as the part of booth, permanent constructions such as also available warehouse, boiler room, office, residence replace.

Adjacent outstanding rafter is a width of cloth film wide only at interval, and it is also little load, and the suspension cable two ends are bound on the strip footing of booth both sides comparatively easy, even can be bound in and hang on the purlin; Outstanding purlin overarm load is very big, should be bound in buriedly on underground the bulk rectangular slab of stone or useless prefabricated concrete element, pulls up with anti-loosening.Must adopt the overarm except that meeting very complicated landform or canopy shape, ordinary circumstance is only enough with outstanding purlin and outstanding rafter.Outstanding purlin is directly propped up from ground by the pendulum post, and outstanding rafter is shelved on outstanding purlin top, will hang rafter with carriage in the middle of both and hold up 10～15 centimetres, in case the recessed flowing water of canopy film is stopped and ponding by outstanding purlin.Outstanding purlin sectional area is bigger, and the carriage lower end is fastening with U font stud; Carriage upper end has a groove, will hang rafter together with clamping in the bundle film band embedded groove, adds in case of necessity and uses screw, make hold tighter.The pendulum post is held slightly and is free end, and suspension column is done the spherical linkage connection by the mortar shape basis that last plane is provided with pit.If establish auxiliary equipment such as illumination, ventilation, spraying and skylight, all available U font stud is installed on the outstanding purlin in the booth.

Bundle film band is a kind of the canopy film to be buckled the spill ribbon-shaped members of bundle on outstanding rafter, and the cross section is the C font, and the elastic force that utilizes bundle film band inwardly to tighten makes the tight bundle of canopy film between bundle film band negative camber and outstanding rafter.Tight Shu Liying is suitable with canopy film tearing strength.

The used outstanding rafter of the utility model, outstanding purlin and pendulum post three-major-items all are two-force member, can give full play to the service efficiency of material; Suspension cable booth both direction is in length and breadth pind down by tough suspension cable all, although the canopy face is softly tall and big, still easily keeps stable under the wind-force effect, also anti-crushing by snow; The suspension cable diameter is little, and the shading area is also little; The booth area is big, can effectively improve the heat conduction loss of land utilization rate and minimizing building enclosure and soil; The space is big in the canopy, and thermal capacitance is big, and the temperature lifting is slow, and at severe cold season, ceiling is airtight, and nearly noon hot-air floats on that sheaf space does not make effusion on the booth, reduces the energy and runs off, and lower floor's temperature also can not rise so high; Can also alleviate harm such as waterlogging caused by excessive rain, arid in addition.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the transverse cross-sectional view of arch suspension cable booth.

Fig. 2 is the arch suspension cable booth longitudinal sectional drawing of building on the level land.

Fig. 3 is the arch suspension cable booth longitudinal sectional drawing of building in the slope.

Fig. 4 is canopy face partial structurtes figure.Fig. 5 is canopy face partial structurtes figure.

Shown in Fig. 1,2,4,5 is according to a kind of arch suspension cable plastic tunnel that is suitable for the level land building that the utility model proposes, form by four lines pendulum post 1 and seven outstanding purlins 2 and outstanding rafter 3 etc., the neighbor distance of outstanding rafter should be slightly less than the door fabric width of used plastic film 4, so that reserve the button Shu Yuliang at plastic film edge, bundle film band 5 embeds together with plastic film 4 and outstanding rafter 3 in the groove of carriage 6 upper ends and clamps, carriage 6 lower ends are fastened on the outstanding purlin 2 with U font stud 7, and outstanding purlin 2 is involved in length and breadth with outstanding rafter 3.Outstanding purlin 2 two ends lie in buried on the bulk rectangular slab of stone or useless concrete prefabricated parts 9 of ground below 8, and outstanding rafter two ends are bound on the strip footing 10 of shed both sides, and pendulum post 1 will hang purlin 2 by the requirement of canopy shape to be propped up, and each suspension cable is tightened the formation booth.

Shown in Fig. 1,3,4,5 is that the suspension cable plastic tunnel in the foregoing description is built according to gesture on hillside fields 11, can strengthen the distance between parabolic outstanding purlin supporting-point and not increase the tension force that hangs purlin, promptly look different gradient and can correspondingly reduce the center pillar line number, when the gradient is suitable, can fully phase out center pillar.

Claims (4)

1, a kind of plastic tunnel, it is by the plastic film that covers booth and hold the skeleton of wearing plastic film and forms, and the edge that it is characterized in that plastic film (4) is directly tightly restrainted in the outstanding rafter (3) of suspension cable skeleton by bundle film band (5) and is upward formed the booth coverage rate.
