Abstract
The utility model discloses a composite pipe made of an anisotropic material. The composite pipe is formed by an outer-layer polyvinyl chloride (PVC) plastic pipe, a middle-layer steel pipe and an inner-layer PVC plastic pipe. Anisotropic material fillers are poured in the outer wall of the inner-layer PVC plastic pipe and the outer wall of the middle-layer steel pipe, the inner pipe, the middle pipe and the outer pipe are fastened together, and a supporting device is arranged among the inner pipe, the middle pipe and the outer pipe and can guarantee a relative position relation among the three pipes. The composite pipe made of the anisotropic material is high in rigidity and strength, acid-proof, resistant to corrosion, anti-aging and long in service life.
Description
Technical field
The utility model belongs to the improvement of framework of glasshouse big shack, particularly a kind of unlike material composite pipe.
Background technique
Along with expanding economy, the progress of society, people are more and more higher to the quality safety requirement of agricultural products, and in modern agriculture cultivation, planting technology, the application of warmhouse booth is also more and more general.At first, the skeleton of warmhouse booth generally adopts traditional bamboo pole, but the intensity of bamboo pole is low, corrosion-resistant, and working life is short, and maintenance cost is high; Along with development and the popularization of booth technology, used gradually steel pipe and pvc pipe to replace traditional bamboo pole afterwards, but acidproof, the corrosion-resistant of steel pipe, price is high, and intensity, the rigidity of pvc pipe are low; Adopted afterwards again inorganic glass-fiber reinforced plastic as the skeleton of booth, but still there is the difficult problem that price is high, inconvenience is installed in inorganic glass-fiber reinforced plastic.
Therefore, the utmost point is necessary to provide a kind of novel framework of glasshouse big shack, the shortcoming that exists to overcome above-mentioned prior art.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of corrosion resistance is strong, stiffness and strength is large, big-canopy framework unlike material composite pipe easy for installation and long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of unlike material composite pipe, it is made of outer PVC plastic tube, middle level steel pipe and internal layer PVC plastic tube, internal layer PVC plastic tube outer wall and middle level outer wall of steel pipe cast unlike material packing are provided with support device between inner tube, the tube and the outer tube.
As a kind of preferred technological scheme, the support device between described inner tube, the tube and the outer tube comprises and is fixedly mounted on the inner and outer pipes supporting pin that is circumferential distribution on the steel pipe walls of described middle level.
As a kind of preferred technological scheme, described unlike material packing is the magnesite modification material.
owing to having adopted technique scheme, a kind of unlike material composite pipe, by outer PVC plastic tube, middle level steel pipe and internal layer PVC plastic tube consist of, the outside is installed on the steel pipe of described middle level is resisted against described outer PVC plastic pipe inner wall, inner end is resisted against the support device on described internal layer PVC plastic tube outer wall, it has guaranteed internal layer PVC plastic tube, relative position relation between middle level steel pipe and outer PVC plastic tube, inner and outer pipes adopts the PVC plastic tube, cast unlike material packing between inner and outer pipes, with described inner tube, middle pipe and outer tube tighten together, steel pipe is between inner and outer pipes, do not contact with air, acidproof, corrosion-resistant, anti-aging, and steel pipe can guarantee the intensity of unlike material composite pipe, this unlike material composite pipe rigidity, intensity is high, acidproof, corrosion-resistant, anti-aging, long service life.

Embodiment
Below in conjunction with attached Fig. 1 and 2 and embodiment, the utility model is described in further detail.In the following detailed description, only by the mode of explanation, some one exemplary embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that do not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
as depicted in figs. 1 and 2, a kind of unlike material composite pipe, it is by outer PVC plastic tube 1, middle level steel pipe 2 and internal layer PVC plastic tube 3 consist of, internal layer PVC plastic tube 3 outer walls and middle level steel pipe 2 outer wall cast unlike material packings 5, described internal layer PVC plastic tube 3, support device between middle level steel pipe 2 and outer PVC plastic tube 1 comprises and is fixedly mounted on the inner and outer pipes supporting pin 4 that is circumferential distribution on steel pipe 2 walls of described middle level, the quantity of inner and outer pipes supporting pin 4 can axially arrange three or four along middle level steel pipe 2 walls, can be also more, to satisfy usage requirement as target, inner and outer pipes supporting pin 4 can guarantee outer PVC plastic tube 1, relative position relation between middle level steel pipe 2 and internal layer PVC plastic tube 3, described unlike material packing 5 is the magnesite modification material, specifically, stir into pasty state liquid with acid resistant alkali magnesite modification material and solution by formula rate.
Basic principle of the present utility model, major character and advantage of the present utility model have more than been described.The technician of the industry should understand; the utility model is not restricted to the described embodiments; describe in the above embodiments and specification principle of the present utility model just is described; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.
