Abstract
The utility model provides a novel agricultural vinyl house skeleton, it includes an arc inside and outside supporting beam, pulling force string, its technical essential is: the inner and outer arc-shaped supporting beams are respectively provided with a W-shaped double groove along the arc surface, tension strings are evenly distributed between the inner and outer arc-shaped supporting beams, and the inner sides of the inclined edges at two sides of at least one W-shaped double groove are respectively provided with an arc-shaped limiting groove which extends outwards. The utility model is characterized in that: can prevent the drunkenness of the shed surface of the greenhouse, and is provided with a double-layer plastic greenhouse shed surface structure, so that the structure is more reasonable, the heat preservation effect is good, and the service life of the shed surface is greatly prolonged. In addition, the strength is relatively increased from the mechanical point of view.
Description
Technical field
The utility model belongs to the agricultural facility technical field, specifically a kind of metallic framework that is used to build double-deck farm plastic greenhouse.
Background technology
Along with improving constantly of people's living standard, the consciousness of the scientific farming in town and country, scientic planting and aquaculture is more and more stronger, and wherein farm plastic greenhouse is widely used.At present, the employed big-canopy framework in vast town and country mainly contains two kinds: a kind of is to adopt bamboo-wood structure, and this structure is because intensity is low, need annual repair and replacement, the canopy inner column is also more in addition, and floor space is big, but also keep the sun off, more be unfavorable for mechanically actuated being eliminated gradually; Another kind of then be the frame of steel semi-arched structure, the frame of this steel design also mainly is with a kind of bamboo-wood structure before replacing.Recently, market occurred a kind of outside skeleton arch face have the structure of V-type groove, although this structure and existing common steel big-canopy framework, has certain progress aspect intensity and the saving material, but also there is irrational factor, as: when single lacing wire is embedded in the V-type groove spacing canopy face, because the ductility of plastic tunnel is limited, if tight (degree of depth that is the embedded V-type groove of lacing wire is dark) that lacing wire is drawn, what then the canopy face was drawn is also very tight, even gauffer can appear, time one length will surpass fatigue limit and rupture; If draw very absent-mindedness because the big-canopy framework spacing is certain, the influence that then is subjected to extraneous wind is play back and forth just, the plastic greenhouse face is friction back and forth on metallic framework, time one is long also can rupture.
Summary of the invention
The purpose of this utility model provide a kind of rational in infrastructure, and utilize two lacing wires or spacing jump ring can make the novel agricultural big plastic hot-shed with it that booth canopy face can't play.
The purpose of this utility model is achieved in that it comprises the inside and outside support beams of arc, pulling force string, it is characterized in that inside and outside arc support beams upper edge cambered surface is respectively arranged with a dual-cavity that vertically is the W type, is being evenly equipped with the pulling force string between the support beams inside and outside the arc.
The utility model also is included in the inside and outside support beams of the arc institute W type dual-cavity of setting respectively as required, wherein have at least the inboard of the both sides hypotenuse of a W type dual-cavity to be respectively arranged with an abducent arc limited impression, in the arc limited impression, be provided with the spacing jump ring of spacing plastic, thermal-insulation film.The set arc limited impression of both sides hypotenuse of above-mentioned W type dual-cavity is symmetrically arranged.
The utility model is because the outer support beams of arc is provided with a W type dual-cavity, and be respectively arranged with an abducent arc limited impression in the inboard of W type dual-cavity both sides hypotenuse, then can be in W type groove simultaneously with two adjacent lacing wires or the spacing booth canopy of spacing jump ring face, thereby prevent the play of booth canopy face, and double-layer plastic booth canopy face structure is set, make structure more reasonable, high insulating effect has not only also prolonged service life of canopy face greatly.Also increased intensity relatively from the mechanics angle in addition, pulling force string and the easier welding of inside and outside support beams.

Embodiment
Example 1
Shown in Fig. 1-3, among the figure 3 is the outer support beams of arc, cambered surface is provided with a W type dual-cavity 1 longitudinally on support beams outside arc 3, the inboard of the both sides hypotenuse of W type dual-cavity 1 is symmetrically arranged with an abducent arc limited impression 2 respectively, the inboard of support beams 3 is symmetrically arranged with support beams 5 in the arc equally outside arc, be evenly equipped with pulling force string 4 inside and outside the arc between the support beams, in arc support beams 5 on cambered surface be provided with a W type dual-cavity 7 and an arc limited impression 6 longitudinally.Said structure all adopts welding.This structure when mounted, earlier the arc brace summer of making evenly is provided with for about 2 meters by spacing, wherein the upper end of inside and outside brace summer is fixed in the gap 10 at wall top, and its lower end canonical is fixed on the base 11 on ground, between two adjacent brace summers, also be provided with metal pull bar 12 in addition, whole skeleton is become one structure.Behind the support frame location, plastic, thermal-insulation film 9 begins to mat formation, insulation film is blocked and located in the back of mating formation with the spacing jump ring 8 of spacing plastic, thermal-insulation film (metal or nonmetal all can), longitudinally set in the W type dual-cavity 2 on the support beams inside and outside each have spacing jump rings 8, this spacing jump ring 8 is by lock retainer 13 lockings and the location that are arranged on the base 11, to prevent play.The optional as required two-sided plastic tunnel with said structure of user also can be selected Fig. 4, the two-sided plastic tunnel that has another kind of spacing jump ring 14 shown in Figure 5 as required for use.
Claims (3)
1, a kind of novel agricultural big plastic hot-shed with it, it comprises the inside and outside support beams of arc, pulling force string, it is characterized in that inside and outside arc support beams upper edge cambered surface is respectively arranged with a dual-cavity that vertically is the W type, is being evenly equipped with the pulling force string between the support beams inside and outside the arc.
2, agricultural booth frame according to claim 1, it is characterized in that inside and outside arc support beams the W type dual-cavity that is provided with respectively, wherein have at least the inboard of the both sides hypotenuse of a W type dual-cavity to be respectively arranged with an abducent arc limited impression, in the arc limited impression, be provided with the spacing jump ring of spacing plastic, thermal-insulation film.
3, agricultural booth frame according to claim 2 is characterized in that the set arc limited impression of both sides hypotenuse of W type dual-cavity is symmetrically arranged.
