Abstract
A method for improving the wind load and snow load capability of a greenhouse comprises the steps of hanging a supporting rod on every other truss of trusses of the greenhouse and arranging the supporting rods at the positions 1 to 1.5 m under the centers of the trusses, wherein the span of the trusses is 10 to 14 m; arranging a pull rope mechanism close to the gable wall which is formed in the greenhouse, fixedly connecting a rope of the pull rope mechanism with pull rings which are arranged on the supporting rods and controlling the pull rope mechanism to enable the lower portions of the supporting rods to be hung in the air and located under the inclined state, wherein the horizontal inclined angle of the supporting rods is 10 to 15 degrees; controlling the pull rope mechanism in the opposite direction under the climate condition of more than five level of wind force or the moderate snow to enable the supporting rods to fall and to be supported on a supporting plate which is placed on the ground; performing snow removal after the wind or the snow and controlling the pull rope mechanism to enable the supporting rods to be restored to the original inclined state and performing the normal field operation. According to the method for improving the wind load and snow load capability of the greenhouse, the normal operation of the greenhouse is not affected, the reinforcement effect on the trusses can be achieved under bed weather such as the wind and the snow, the operation is simple, and the time and the effort are saved.
Description
Technical field
The present invention relates to a kind ofly improve that booth wind carries, the method for snow load ability.
Background technology
Plastic greenhouse is with its good heat insulating ability, simple temperature control means, relatively cheap construction price and good effect of high-yield, deeply be subject to the favor of vast farmers, but along with the development of vegetables in improper season commodity economy, not only the quantity of booth is more and more, the area of monomer canopy is also in continuous increase, from original 30,40 meters, develops into present 100,120 meters.The way of this simple prolongation booth length is not only subject to the restriction of geographical conditions, has caused great inconvenience also to all too many levels in production management process.Concentrate the construction of booth in flakes to need technically to consider the problem of daylighting between the canopy of front and back simultaneously.Therefore, in the situation that canopy height is definite, booth span is less, and the area in the front vacant lot of canopy just correspondingly increases, the waste that objectively causes soil to utilize; This just requires the span of booth correspondingly to increase, but the booth of large span is except higher to the requirement of truss material, also will consider that the way that increases support under truss guarantees the roofing of booth, the load setting value of lighting surface.Particularly wind, snow when larger, cause truss carrying excessive, easily truss are bent, backfin, and booth is caved in.
Summary of the invention
The technical problem to be solved in the present invention is to provide one neither affects normal operation in booth, under the bad weathers such as wind, snow, booth truss is played to reinforcement effect again and simple to operate, time saving and energy saving raising booth wind carries, the method for snow load ability.
Technology of the present invention solves:
Improve that booth wind carries, a method for snow load ability, comprise the following steps:
On the truss of A, the booth that is 10m-14m in span, every a truss, articulate a support bar, described support bar is arranged on 1m-1.5m place under truss center deviation;
B, in booth, near gable position, pull rope mechanism is set, by affixed the draw ring of establishing on the rope of pull rope mechanism and support bar, manipulation pull rope mechanism makes support bar bottom unsettled and in heeling condition, and its level inclination is 10 °-15 °;
C, at wind-force, exceed under Pyatyi or weather conditions more than moderate snow, handle pull rope mechanism in the other direction, support bar is fallen and be supported on to be placed on ground supporting plate;
D, when wind scrape later or snow after remove the snow, handle pull rope mechanism, make support bar return to initial dip state, to carry out normal farm work.
The bottom of described support bar is Collapsible structure, according to geopotentia difference, the stroke of support bar bottom is finely tuned, and support bar is supported on supporting plate completely, to improve support effect.
The invention has the beneficial effects as follows:
This raising booth wind carries, the method for snow load ability, simple to operate, time saving and energy saving, at wind-force, exceed under Pyatyi or weather conditions more than moderate snow, handle pull rope mechanism, make they sup-port to truss, play reinforcement effect on the ground, in order to avoid by truss press-bending, backfin, booth is caved in; After wind, snow, make support bar unsettled and in heeling condition, can normally carry out production operation.
Accompanying drawing explanation
Fig. 1 is booth interior schematic diagram of the present invention.
Embodiment
Embodiment 1
As shown in the figure, the raising booth wind the present invention relates to carries, the method for snow load ability, comprises the following steps:

B, in booth, near gable position, pull rope mechanism is set, by affixed the draw ring of establishing on the rope of pull rope mechanism and support bar, manipulation pull rope mechanism makes support bar bottom unsettled and in heeling condition, and its level inclination is 12 °;
C, at wind-force, exceed under Pyatyi or weather conditions more than moderate snow, handle pull rope mechanism in the other direction, support bar is fallen and be supported on to be placed on ground supporting plate;
D, when wind scrape later or snow after remove the snow, handle pull rope mechanism, make support bar return to initial dip state, to carry out normal farm work.
Embodiment 2
The raising booth wind the present invention relates to carries, the method for snow load ability, comprise the following steps: on the truss of A, the booth that is 14m in span, every a truss, articulate a support bar, described support bar is arranged on 1.4m place under truss center deviation, and the bottom of described support bar is Collapsible structure;
B, in booth, near gable position, pull rope mechanism is set, by affixed the draw ring of establishing on the rope of pull rope mechanism and support bar, manipulation pull rope mechanism makes support bar bottom unsettled and in heeling condition, and its level inclination is 14 °;
C, under wind-force exceedes six grades or more than moderate snow weather conditions, handle pull rope mechanism in the other direction, support bar is fallen and is supported on to be placed on ground supporting plate;
D, when wind scrape later or snow after remove the snow, handle pull rope mechanism, make support bar return to initial dip state, to carry out normal farm work.
Claims (2)
