Abstract
The utility model discloses a novel high-strength nanometer heart-shaped composite steel tube used by an agricultural greenhouse, and relates to an improvement of a steel tube, in particular to a composite steel tube used by an agricultural greenhouse. The section of a steel tube body (1) is heart-shaped, the upper end of the section of the steel tube body (1) is provided with a groove (2), and the lower end of the section of the steel tube body (1) gradually contracts. The novel high-strength nanometer heart-shaped composite steel tube leads the wall thickness of the steel tube applied on thegreenhouse skeleton to be greatly reduced, and reduces the production cost of the steel tubes. Along with the development of dimensions agriculture, a great amount of steels can be saved, subsequently, great economic benefits and social benefits can be brought to environmental protection and energy conservation.
Description
Technical field:
The utility model relates to a kind of improvement of steel pipe, is specifically related to a kind of composite steel tube that is applied to agricultural greenhouse.
Background technology:
Along with the development of the appropriate scale of agriculture, agricultural greenhouse is more and more, more and more receive an acclaim, but agricultural greenhouse all needs a large amount of steel pipes to build skeleton.Price of steel product rapidly went up over the past two years, big-canopy framework to build cost more and more higher, along with various booth scales, shape are increasing, requirement to required thickness of steel pipe is more and more higher, otherwise be difficult to support scale, the increasing various big-canopy frameworks of shape, these big-canopy frameworks all need to consume a large amount of steel pipes, consume a large amount of steel pipes, steel are not only with high costs, and also very unfavorable for the environmental problem that can't bear the heavy load, also consume quite big for the energy.
Booth steel pipe commonly used at present all is to adopt coating steel pipe, this common steel tube is built in big-canopy framework, the top major part of steel pipe is wrapped in plastic film, residing environment very severe, comprise high temperature, humidity, airtight, other gas or the like, so the life-span that common steel tube is applied in the big-canopy framework is shortened greatly, usually can't bear with regard to corrosion in a short time.
The utility model content:
The purpose of this utility model provides a kind of novel high-strength agricultural greenhouse booth heart-shaped composite steel tube of nanometer, it provides a kind of chapped pipe of building the agricultural greenhouse skeleton that is applicable to, it has long service life, save to use steel, reduce use cost, help the advantage of environmental protection and energy saving.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: the cross section of steel pipe main body 1 is for heart-shaped, and the upper end in steel pipe main body 1 cross section is provided with groove 2, and shrink gradually the lower end in steel pipe main body 1 cross section.
In the utility model, the contraction gradually of the lower half circle of steel pipe main body 1, upper semi-circle cross section integral body is greater than lower half circle, lower semisection was bent when steel pipe main body 1 was applied on the big-canopy framework because lower half circle shrinks to some extent, after bending because the elastic deformation of itself, make the bearing capacity of steel pipe main body 1 strengthen, can support bigger weight, last end section is being used lengthening deformation owing to be provided with groove 2, still can keep original stressed because groove 2 makes to diminish.Under equal stress condition, use the needed pipe thickness of the heart-shaped steel pipe main body pipe thickness more required little a lot of than round steel pipe.
The utility model can reduce the production cost of steel pipe so that the thickness of steel pipe that is applied on the big-canopy framework reduces greatly.Along with the development of the appropriate scale of agriculture, can save a large amount of steel, save steel for environmental protection, energy-conservation very large economic benefit and social benefit arranged all.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, Fig. 2 be the A-A of Fig. 1 to cutaway view, Fig. 3 is the structural representation of embodiment two, Fig. 4 is the structural representation of embodiment three.
Embodiment:
Embodiment one, referring to Fig. 1-2, this embodiment by the following technical solutions: the cross section of steel pipe main body 1 is heart-shaped, and the upper end in steel pipe main body 1 cross section is provided with groove 2, and shrink gradually the lower end in steel pipe main body 1 cross section.
In this embodiment, the contraction gradually of the lower half circle of steel pipe main body 1, upper semi-circle cross section integral body is greater than lower half circle, lower semisection was bent when steel pipe main body 1 was applied on the big-canopy framework because lower half circle shrinks to some extent, after bending because the elastic deformation of itself, make the bearing capacity of steel pipe main body 1 strengthen, can support bigger weight, last end section is being used lengthening deformation owing to be provided with groove 2, still can keep original stressed because groove 2 makes to diminish.Under equal stress condition, use the needed pipe thickness of the heart-shaped steel pipe main body pipe thickness more required little a lot of than round steel pipe.In practical application detected, the heart-shaped steel pipe of condition of equivalent thickness is stressed to be 1.4 times of round steel pipe.
This concrete enforcement side can reduce the production cost of steel pipe so that the thickness of steel pipe that is applied on the big-canopy framework reduces greatly.Along with the development of the appropriate scale of agriculture, can save a large amount of steel, save steel for environmental protection, energy-conservation very large economic benefit and social benefit arranged all.
Embodiment two, referring to Fig. 3, this embodiment is in the increase of the outside of steel pipe main body 1 composite plastic layer 3 is arranged with the difference of embodiment one, composite plastic layer 3 covers on the outer surface of steel pipe main body 1.Increasing composite plastic layer 3 both can increase the intensity of steel pipe main body 1, prevented pipe deformation, crushed; Composite plastic layer 3 also can prolong simultaneously the service life of steel pipe, because can delay the corrosion of steel pipe.Other composition is identical with embodiment one with annexation.
Embodiment three, referring to Fig. 4, this embodiment is in the increase of the outside of steel pipe main body 1 nano microsphere plastic layer 4 is arranged with the difference of embodiment one.Increase nano microsphere plastic layer 4 and both can increase the intensity of steel pipe main body 1, the compression strength of nano microsphere plastic layer 4 itself is very high, can further prevent pipe deformation, crush; Nano microsphere plastic layer 4 also can prolong simultaneously the service life of steel pipe, because can delay the corrosion of steel pipe.Other composition is identical with embodiment one with annexation.
