Description
Technical field:
The utility model relates to the technical field of plastic cover greenhouse film for agricultural, particularly a kind of laminated plastics heat preservation greenhouse crossbeam.
Background technology:
The formation of booth is substantially: plastic cover greenhouse film covers the external surface of crossbeam cage construction, by four limit compactings of awning film on earth's surface or imbed underground.So far, formed heat preservation greenhouse.But, what existing this heat preservation greenhouse majority adopted is monolayer plastic awning film, the plastic cover greenhouse film of this individual layer is in the winter time time, heat insulation effect is poor, day and night temperature is large, usually need to be at inside or the full and warm facility of outside interpolation of heat preservation greenhouse, as stove or heating pad passage etc., in addition, also need at the external surface of monolayer plastic awning film, cover straw screen or mat, cotton-wadded quilt etc. to keep the temperature of heat preservation greenhouse inside.Raise at sunrise straw screen or mat or cotton-wadded quilt every day, cover at sunset straw screen or mat or cotton-wadded quilt.Complicated operation, labour intensity is large, also easily causes the damage of plastic cover greenhouse.For solving the bad technical problem of heat preservation greenhouse thermal property of individual layer awning film, operate on the market and given birth to the plastic cover greenhouse film of some double-deckers and even sandwich construction, as the application for a patent for invention of Chinese patent 200810140350.2, wherein recorded the structure of double layer plastic greenhouse film: it is comprised of two layers of plastic film, in the middle of two layers of plastic film, be provided with some support gas columns, lower limb is provided with air-filled pore, and the joining place of Double-layered greenhouse film and Double-layered greenhouse film is fixed on greenhouse bracket by rubber adhesive tape.The shortcoming of this double-deck plastic cover greenhouse film is: support gas column inside and be provided with air, (being similar to the structure of bubble chamber film), can cause Double-layered greenhouse film too fat to move, bulky, and weight increases, and when transportation and laying, is all not easy.And being connected of Double-layered greenhouse film and Double-layered greenhouse film is fixing by rubber adhesive tape and plastic strip, no matter bonding the or screw fastening of heat seal, all caused the complex procedures of laying awning film, and follow-up installation very easily causes the inner gas leakage of Double-layered greenhouse film.Cause also repeatedly inflating and cannot reach desirable heat insulation effect.For another example the application for a patent for invention of Chinese patent 200610070903.2, it is comprised of two layers of plastic film, in two layers of plastic film, be provided with plastic flexible pipe, shut at two of plastic flexible pipe, the outer wall of plastic flexible pipe and both sides plastic foil are bonding, on plastic flexible pipe, be provided with pore, by pore, inflate spreading double-layer plastic film.This double-decker, the flexible pipe of double-layer plastic film inside causes plastic cover greenhouse membrane volume huge, and weight increases, transportation and laying are difficult for, and the bond locations of plastic flexible pipe and awning film very easily ftractures, because of the ductility of plastic cover greenhouse film, cause the double-layer plastic film glomeration that rises.Therefore, also cannot well solve the effect of heat preservation greenhouse constant-temperature warm-keeping.For another example, Chinese patent application ' 201110056806.9 ' disclosed ' a kind of double-layer plastic heat preservation greenhouse film and using method thereof ' is although it has adopted structure cleverly to use air chamber that awning film is divided into both sides, and, mounting method is comparatively simple, but still there is breakage, gas leakage causes changing the technical problems such as film inconvenience.
Therefore, through facts have proved, on awning film, for multilayer Study, be that feasibility is less, for example, between multilayer film, mostly need inflation to make its spreading, form gas-bearing formation.Although this film plays good heat insulation effect, once damaged, bring about great losses, for addressing this is that, there is the scheme that gas-bearing formation is separated into some air chambers.Although the breakage of film only causes the damage of corresponding air chamber,, for the repairing of broken parts, replace and become again insoluble technical problem.
So, for the technological improvement of multilayer booth, rotate back into again in the direction of crossbeam skeleton.Traditional large capplce, is woodwork, bamboo product or metal product, and woodwork, bamboo product shortcoming are that bow member intensity is low, and wind resistance snow ability is easily rotten rotten, needs repairing every year and changes, and operational administrative is inconvenient.Although metal product intensity is high, anti-pressure ability is strong, perishable, cost is high, though adopt zinc-plated, aluminum-plated steel pipe, but still cannot solve the problem of corrosion, although application life more wooden skeleton, bamboo matter skeleton is long, but in humidity, under the environment such as Exposure to Sunlight, application life is still undesirable, general 5-8 needs to change, and, install and usually need welding, civil engineering is more etc., installs and is difficult for.So, how by the structure design of big-canopy framework, make it reach the conception of multilayer booth, become technical barrier, for solving this technical problem, the utility model aims to provide a kind of simple in structure, easy to use, civil engineering is few, sturdy and durable, and wind resistance snow ability is strong, intensity is high, and anti-pressure ability is strong, corrosion-resistant, long service life, installs easily, and the construction cost that builds multi-layer heat preserving booth is low, insulation, moistening effect is good, and replaces the easy a kind of laminated plastics heat preservation greenhouse crossbeam of damaged plastic foil.

The utility model civil engineering is few, only adopts clump to be used for fixedly booth crossbeam, and the utility model, without welding, bundlees etc., and skeleton part all adopts grafting or screw threads to fix, and one can complete skeleton fitting operation spanner.
The fixing fitting of plastic foil is selectively many, without using any instrument, adopts corresponding press mold instrument that plastic foil is pressed abd fixed on booth crossbeam.
Material of the present utility model adopts glass fiber reinforced plastic or resin fibre to make, corrosion-resistant, reaches 20-30 application life.
If there is plastic foil to damage, replace the impaired plastic foil between adjacent two booth crossbeams, processing ease, reduces maintenance cost.
Booth crossbeam is by exclusive device fabrication, maximum span 5-25 rice, and when crossbeam span is 25 meters, can not rupture by pressure-bearing 1 ton hour, intensity is large, and wind resistance snow ability is strong.
The utility model is compared with bilayer or the multilayer booth of prior art, whole civil engineering few (civil engineering is close to earth's surface), cause the duration of sunshine long (can have more 2-4 hour), light transmittance is good, therefore without heating installation is especially provided, temperature can improve 10-40%, is conducive to the increasing both production and income of crops.
