Abstract
The present invention relates to the technical field of a greenhouse framework, which is developed to solve a solarization problem, increase strength and prolong life. The present invention comprises a hollow steel pipe and is characterized in that the outer surface of the hollow steel pipe is coated with a plastic layer, and at the same time, the hollow steel pipe is filled with matrixes. The greenhouse framework has the advantages of low manufacture cost, steel material saving, large press resisting and wind resisting strength, solarization prevention, etc. and is suitable for agriculturally productive popularization and use.
Description
The present invention relates to a kind of big-canopy framework technical field, especially the agricultural booth frame technical field.
The agricultural production progress, booth is come into man of common peasant household, and agricultural booth is produced stylish vegetables and flowers, and people's hollow steel pipe commonly used is as big-canopy framework, as the patent No. is the Chinese patent " no column plastic tunnel " of 95232346.X, and its skeleton is just made for hollow profile steel.Its shortcoming has: not sun-proof, summer, the sun shines down, and it is hot that steel pipe easily absorbs heat, and surface temperature even can surpass 70 ℃ is scalded broken fusing easily so be covered in its surperficial plastic film, causes and leaks, and is not incubated, and the result damages crop growth; Insufficient strength, because skeleton is that hollow steel pipe is made, so skeleton resistance to compression rated wind velocity is limited, and the heavy snow sky once took place, the thick crushing by snow agricultural booth phenomenon of collapsing is destroyed agricultural production; Oxygen barrier not, owing to be hollow steel pipe, its surfaces externally and internally has partly contacted oxygen, and especially in the open, every day, contact had steam, and it is rotten very easily to get rusty, and influences service life; Self is heavy, is the thicker steel pipe of tube wall owing to adopt hollow steel pipe, and own wt is also bigger, is unfavorable for national requirements.
The object of the present invention is to provide a kind of have sun-proof, anti-aging, intensity greatly, again can oxygen barrier, the big-canopy framework that increases the service life greatly.
The technical scheme that realizes the object of the invention is such: this big-canopy framework comprises hollow steel pipe, it is characterized in that described hollow steel pipe outer surface is surrounded by plastic layer, is filled with basic thing in the hollow steel pipe simultaneously.
Above-mentioned plastic layer surface distributed has the rib of reflection ray; Above-mentioned basic thing can be hard, the light building material of low alkali cement, expanded perlite, the mixed system of building glue; Also can be the cement mortar construction material that cement mortar or glass fibre strengthen; Also can be the magnesite class hard light-weight building material of magnesia, magnesium chloride, the mixed system of filling modifying agent.
This big-canopy framework is because the surface is surrounded by plastic layer, can effectively stop the steel pipe heat absorption hot in summer, again because surface reflection lines line, can control the big-canopy framework surface temperature below 50 °, prevent that effectively plastic film is melted boiling hot broken phenomenon, steel pipe filling base thing, both played the oxygen barrier effect, preventing that the steel pipe endosexine is oxidized rots, and prolongs big-canopy framework service life, can strengthen booth intensity again, be difficult for being collapsed by big crushing by snow or being blown off by blast, the base of filling simultaneously thing is the hard light-weight building material, and cost is low, in light weight, can alleviate the big-canopy framework deadweight, can reduce production costs again.The big-canopy framework of new construction can also be saved ferrous materials for country, and under the same specification intensity situation, production cost is low, long service life, and anticorrosion, sun-proof, suitable agricultural greenhouse is applied.
Description of drawings:
Fig. 1. big-canopy framework cross-sectional view of the present invention.
Below in conjunction with accompanying drawing embodiments of the invention are further described.
As shown in the figure: this big-canopy framework has a hollow steel pipe 2, generally can adopt pipe, square steel tube and other geometric type material, diameter is between 15～80 millimeters, wall thickness suits at 0.3～1.8 millimeter, appearance bread one deck plastic layer 1, be generally 0.5～3 millimeter, adopt uvioresistant, ageing-resistant engineering plastics, the plastic layer surface distributed has the rib of reflection ray, be filled with basic thing 3 in the hollow steel pipe simultaneously, can adopt the hard light-weight building material, as low alkali cement, expanded perlite, building rubber/polyethylene alcohol mixes the hard lightweight material of system, also can be magnesia, magnesium chloride, filling modifying agent mixes the hard such as magnesite class of system, lightweight material also can be the cement mortar construction material that cement mortar or glass fibre strengthen.
