Abstract

The utility model relates to a super connection ridgepole greenhouse for greenhouse technology of the agricultural crops heat insulation and wet keeping filed. The utility model is provided with a greenhouse film and a column, and the top end of the column is fixed with a steel strand in length and breadth distribution. An arched bamboo strip is arranged between every two steel strands, and the arched bamboo strip is fixed with the steel strand. The vertical direction along the arched bamboo strip is provided with a steel line, and a support rod is arranged between the steel line and the arched bamboo strip. The utility model well solves the defects of too many columns, weak anti-wind capacity, and low land using efficiency and large quantity of greenhouse film in use for the traditional single greenhouse, at the same time, the utility model well solves the technology problem of high price of the connection ridgepole greenhouse with steel structure. The special feature of the utility model suits to develop in the rural area. What is more important is that the popularization of the utility model makes an intensive management and scale production of the agricultural greenhouse an impossible.

Description

The super large row plastic linked greenhouse

Technical field

The utility model relates to a kind of super large row plastic linked greenhouse that belongs to agricultural crops heat and moisture preserving booth technical field.

Background technology

At present, the peasant of northern country generally uses plastic film and pin to provide the humidity that is fit to its growth, temperature to improve the output of crops as the booth of structure to agricultural crops, compares with the farming technique that tradition falls behind, and this technique effect is very good.Yet there is the shortcoming of following several respects in this simple single household agricultural greenhouse: 1, pin is too much in the booth.Nearly 500 of hundred meters long canopy pin, too much pin not only cause the materials cost to increase, and make the interior space of canopy narrow and small simultaneously, operation is affected, and since the pin bottom be embedded in all the year round underground, very easily rotten under the effect of high temperature bubble, light maintenance in 1 year, overhaul in 2 years, maintenance cost is too high; 2, a little less than the wind loading rating.Wind loading rating is not only relevant with material, and the while is relevant with the degree that film-pressing line compresses plastics.The canopy film is blown open by strong wind, is mostly that the canopy film do not cause because film-pressing line presses tightly.People increase the usable floor area in soil often by the span that increases booth, but along with the increase of span, the radian of bamboo bar bow member reduces thereupon.Radian is more little, and the tightness of film-pressing line just reduces, and plastics are easy to instigate up and down along with wind.If increase the radian of bow member, thereby improve the tightness of film-pressing line press mold, caused the increasing of plastics wind areas thereupon again by the height that improves canopy.Therefore these contradictions that can't be in harmonious proportion reduce the wind loading rating of traditional booth greatly; 3, traditional cold canopy land utilization rate is low, must stay 1 meter wide public land to be used for pile things on line earth anchor between two canopies and the operation path that leaks informaton, and 0.5 meter of canopy inward flange is wide, short can not the utilization, land utilization rate less than 80%; 4, the canopy film consumption of monomer booth is big, has increased and has built cost.

Though the row plastic linked greenhouse that the R﹠D institution that has in recent years adopts steel construction to build has solved the problems referred to above, because its cost too high (50,000 yuan/mu) is difficult in vast rural area and promotes.

Summary of the invention

The purpose of this utility model is exactly to provide a kind of construction cost lower super large row plastic linked greenhouse for solving disadvantages of background technology.

The purpose of this utility model is achieved in that it is provided with canopy film and column, be fixed with the steel strand wires of arranging in length and breadth in the column upper end, between per two steel strand wires, be provided with evenly distributed in the same way arch bamboo bar, the two ends and the steel strand wires of arch bamboo bar are fixed, vertically be provided with steel wire along what arch bamboo bar was arranged, steel wire and steel strand wires are fixed, and are fixed with pole between steel wire and arch bamboo bar.Be provided with vertical backguy in the column both sides, vertical backguy upper end is connected with steel strand wires, and its lower end is connected with the ground weight.The two ends of steel strand wires are strained by the ground weight.

The utility model is compared background technology and is had following advantage: 1. owing to changing the monomer booth into row plastic linked greenhouse, so the utility model land utilization rate, is saved the canopy film more than 98% more than 30%; The column of row plastic linked greenhouse is a concrete column, weight own is big, adding steel strand wires fuses several thousand concrete columns on tens mu of ground, so the utility model anti-strong wind, anti-whirlwind is very capable, the space is big in the canopy, and plant growth is abundant, operation is convenient, raise labour efficiency, long service life is suitable for carrying out intensive management, large-scale production; 2. relative steel construction booth, the utility model cost is cheaper, and 3500 yuan every mu-4000 yuan approximately,

Embodiment

The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, several monomer booths are connected in parallel, form the super large row plastic linked greenhouse that tens mu of ground are unified into a slice, the span of each monomer booth narrows down to 4 meters by 8-10 rice, the radian of arch bamboo bar 5 is big like this, film-pressing line can compress the canopy film, and the canopy film naturally can be not broken by big wind.The column 4 of booth uses the cement column, improves the bearing capacity and the service life of booth column 4.Be fixed with the steel strand wires of arranging in length and breadth 1 in the upper end of column 4, on steel strand wires 1, be fixed with the arch bamboo bar 5 that has been shaped, vertically be provided with steel wire 6 along what arch bamboo bar 5 was arranged, steel wire 6 is fixing with steel strand wires 1, be provided with pole 7 between steel wire 6 and arch bamboo bar 5, the two ends of pole 7 are fixing with steel wire 6 and arch bamboo bar 5 respectively.The effect of pole 7 is the intensity that increases arch bamboo bar 5.Steel strand wires 1 termination is with dropstone 10 tensions, if adopt better as oblique column 8 of Fig. 2 and pinner 9 structure tension effects.For the rigidity that improves steel strand wires 1 and the stability of whole skeleton, as shown in Figure 3, be provided with vertical backguy 12 in the both sides of column 4, vertical backguy 12 upper ends are connected with steel strand wires 1, and its lower end is heavy stone 11 to be arranged and strain vertical backguy 12.For more convenient booth leaks informaton, as shown in Figure 1, on arch bamboo bar 5, be provided with the device 2 that leaks informaton, tension is led chain 3 and can be leaked informaton or make the canopy film to reset easily.
