Description

Production multilayer booth crossbeam pultrusion system
Technical field:
The utility model relates to the technical field of hot house film for agricultural, particularly a kind of production multilayer booth crossbeam pultrusion system.
Background technology:
Traditional large capplce, is woodwork, bamboo product or metallic article, 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 metallic article 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 service life more wooden skeleton, bamboo matter skeleton is long, but in humidity, under the environment such as Exposure to Sunlight, service life is still undesirable, general 5-8 needs to change, and, install and usually need welding, civil engineering etc., installs and is difficult for.
The formation of booth is substantially: hot house film covers the outer surface of crossbeam skeleton structure, 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 hot house 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 outer 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 hot house.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 hot house film of some double-deckers and even multilayer mechanism, 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 hot house 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 hot house 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 hot house 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.
But, 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.
Therefore,, for the technological improvement of multilayer booth, rotate back into again in the direction of crossbeam skeleton.Require crossbeam both sturdy and durable, wind resistance snow ability is strong, and intensity is high, and anti-pressure ability is strong, require again corrosion-resistant, long service life, and, with low cost, install easily.For these characteristic of property, conventional plastic PVC is difficult to reach, therefore, fiberglass or resin fibre become first-selection, still, and for the extruding equipment of fiberglass or resin fibre, only can make the pultrusion of vertical article, for the arch-type structure of booth crossbeam skeleton, there is no corresponding production equipment.If use existing extruding equipment to extrude vertical configuration crossbeam hot bending again, although can realize, once span surpasses 5 meters, anti-pressure ability reduces greatly, causes insufficient strength, the problem of easy fracture.In addition, how on crossbeam, to realize the object of multilayer booth, also become insoluble technical problem.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming existing in prior art, provide a kind of simple in structure, easy to use, for arch formula booth crossbeam, produce specially, the crossbeam arch formula span of producing is large, and anti-pressure ability is strong, and intensity is high, corrosion-resistant and can connect multilayer awning film, be beneficial to a kind of production multilayer booth crossbeam pultrusion system that forms multilayer booth.
