Abstract
The utility model relates to a novel agricultural greenhouse frame, comprising arc-shaped supporting beams and pull strings. The novel agricultural greenhouse frame is characterized in that a longitudinal W-shaped groove is arranged along the upper arc-shaped face of an outer arc-shaped supporting beam, and an inner arc-shaped supporting beam is arranged on the inner side of the outer arc-shaped supporting beam; the pull strings are uniformly arranged between the inner arc-shaped supporting beam and the outer arc-shaped supporting beam. Because the W-shaped groove is arranged on the outer arc-shaped supporting beam, and a heat insulating greenhouse cover can be limited by two adjacent pull ribs in the W-shaped groove simultaneously, and therefore, the utility model can prevent a greenhouse cover from moving, enable the structure of a greenhouse to be more reasonable, prolong the service life of the greenhouse cover, and besides, increase strength relatively in the aspect of mechanics.
Description
The utility model belongs to the agricultural facility technical field, specifically a kind of metallic framework that is used to build farm plastic greenhouse.
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.
The purpose of this utility model provide a kind of rational in infrastructure, and can make two lacing wire novel agricultural big-canopy frameworks that booth canopy face can't play.
The purpose of this utility model is achieved in that it comprises arc support beams, pulling force string, it is characterized in that cambered surface is provided with a vertical W type groove on support beams outside arc, the inboard of support beams is provided with support beams in the arc in the arc, is being evenly equipped with the pulling force string inside and outside the arc between the support beams.
The utility model is because the outer support beams of arc is provided with a W type groove, then can be in W type groove simultaneously with two the adjacent spacing booth canopy of lacing wire faces, thereby prevent the play of booth canopy face, make structure more reasonable, can prolong the 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.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a stereochemical structure simplified schematic diagram of the present utility model
Fig. 2 is a user mode schematic diagram of the present utility model
Fig. 3 is that the A-A of Fig. 2 is to amplification profile
Shown in Fig. 1-3, among the figure 1 is the outer support beams of arc, cambered surface is provided with a W type dual-cavity 2 longitudinally on support beams outside arc 1, the inboard of support beams 1 is provided with support beams 4 in the arc of metal garden pipe or garden cylindricality outside arc, be evenly equipped with pulling force string 3 inside and outside the arc between the support beams, adopting 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 brace summer is fixed in the gap 8 at wall top, and its lower end canonical is fixed on the base 9 on ground, between two adjacent brace summers, also be provided with metal pull bar 7 in addition, whole skeleton is become one structure.Behind the support frame location, the plastic, thermal-insulation film begins to mat formation, mat formation the back with lacing wire 6 (metal or nonmetal all can) tension location insulation film, on each support beams, longitudinally be provided with two lacing wires 6 in the W type dual-cavity 2, this lacing wire is by lock retainer 10 lockings and the location that are arranged on the base 9, to prevent play.Optional as required the single face plastic tunnel of user with said structure, also can select two-sided plastic tunnel as required for use, promptly on the basis of said structure, the brace summer 4 plastic, thermal-insulation film of also mating formation in arc, the back of mating formation is spacing with being sleeved in the arc opening plastics limit casing 5 on the support beams 4.
Claims (2)
1, a kind of novel agricultural big-canopy framework, it comprises arc support beams, pulling force string, it is characterized in that cambered surface is provided with a vertical W type groove on support beams outside arc, the inboard of the outer support beams of arc is provided with support beams in the arc, is being evenly equipped with the pulling force string inside and outside the arc between the support beams.
2, agricultural booth frame according to claim 1 is characterized in that also being set with on the support beams plastics limit casing of opening in the arc of metal garden pipe or garden post.
