Description
Technical field
The utility model is related to the support bar and the system of support bar of the warmhouse booth for agricultural cultivation, plantation and cultivation
Make device.
Background technology
In recent years, with the popularization of green house of vegetables, warmhouse booth is used widely in each area, according to each area
The need for the difference and Different Crop of natural environmental condition and different purposes, people make improvement to traditional greenhouse one after another.
Traditional greenhouse is typically constituted due to being limited by original economic condition using cement post and horizontal skeleton, and skeleton typically uses bamboo
Bar.With expanding economy and the increasing trend of warmhouse booth, it is necessary to which structure is more firm, more convenient skeleton of constructing
Material.The material of steel construction turns into the preferred material of warmhouse booth.But the skeleton of metal material has one in application process
A little problems, first cost of manufacture are high, secondly, corrosion-resistant.For cost it is higher the problem of, many people are used as bone using steel pipe
Frame material, for steel pipe it is corrosion-resistant poor the problem of, in the external coated paint or other waterproof materials of steel pipe, in order to solve just
Property and the problem of poor toughness, some use outer layers set the method that enhancement layer and internal layer fill filler, and this method typically fills water
Mud or the material for being equal to cement are outside general using cement or magnesium chloride.
But external coated paint or other waterproof materials function only as the effect of antirust, it is impossible to play a part of reinforcing, and
And coating antirust paint or waterproof material can not be lasting, rust-proof effect is poor.Using cement material, its combination degree is poor for outside, tough
Property is poor.
Chinese patent literature CN101322465B discloses a kind of support lever for greenhouse frame and its process equipment and preparation side
Method, the purpose of the utility model be to provide it is a kind of it is corrosion-resistant, inexpensive, do not draw film, high intensity, the Keelof green house material of high tenacity
Material, and framework material processing method and process equipment.In order to achieve the above object, the utility model takes following scheme：
Including a hollow steel pipe, filling solidifies and solidifies a floor height molecule inorganic material outside macromolecule inorganic material, steel pipe in steel pipe.Its
In, the macromolecule inorganic material of filling solidification in the steel pipe, and the seamless bonding of steel pipe internal-surface, the steel pipe outer covering
Solidify macromolecule inorganic material, with the seamless bonding of outer surface of steel tube, steel pipe is not got rusty by the dioxygen oxidation in air, prolong
Long life.Wherein, the section of the framework material is rounded or polygon, smooth outer surface, prevents from scratching plastics thin
Film.Wherein, the macromolecule inorganic material solidified in the steel pipe outside the solidification macromolecule inorganic material and the steel pipe of filling, by
Weight is mixed with water than the talcum powder for 4% to 35%, 64% to 95% calcium stone flour, 1% to 0.01% chemical addition agent
Conjunction stirs into slurry and formed.Wherein, the chemical addition agent is first class cellulose and aqueous glass glue, and calcium stone flour is selected hard stone flour
Broken to form, chemical addition agent can make that macromolecule inorganic material intensity is bigger, and the bonding with steel pipe is more firm.Wherein, the steel
Solidification macromolecule inorganic material in pipe outside the solidification macromolecule inorganic material and the steel pipe of filling, also doped with glass fibre
Silk, strengthens the toughness of macromolecule inorganic material and the bulk strength of framework material.
Using the way of inside and outside solidification macromolecule inorganic material in above-mentioned technical proposal, this largely reaches corrosion resistant
Erosion, low cost, do not draw film, high intensity, the purpose of high tenacity, but the mesh in practice process due to filled therewith in steel pipe
One increase intensity, the second rust resistance and corrosion resistance, but because slurry is in steel duct, the length of steel pipe is longer, therefore slurry is short
Shaping can not be condensed within time, and is difficult to reach seamless contact with steel pipe, its etch-proof effect is poor.If
Shaping can not be condensed within the slurry short time, it is elongated to result in process time first, adverse effect is brought for transport and installation.
Simultaneously as inside and outside is solidification macromolecule inorganic material, the weight of skeleton is actually increased, and this is to greenhouse
Construction it is particularly disadvantageous because the support of greenhouse upper film need to be supported with many support bars, if support bar is heavier, this
The weight of body proposes higher requirement to lower support, and this does not match with the increasing development trend of current greenhouse, more next
Bigger greenhouse needs less support and firmer support, therefore will try to reduce the weight of upper support bar, so as to
More effectively increase the span of warmhouse booth, so the weight of support bar obviously has great importance to warmhouse booth, especially
Come interim in burst weather condition, such as southern frost sleety weather, just basic to damage all greenhouses, reason is exactly to hold
Beijing South Maxpower Technology Co. Ltd's power is poor, therefore proof strength and toughness turn into the emphasis for expanding warmhouse booth development while reducing own wt.
