The central authorities of pipe for supporting structure of the present invention are the supporting element of metallic material, play the effect that completely cuts off intermediate filling layer and support whole tubing.Supporting element can adopt metallic material such as iron and steel, lead, owing to be not exposed in the air, is difficult for being corroded, and damages or change to reclaim at street lamp can reuse later, has saved materials such as iron and steel.Middle packed layer polyurethane is a kind of high-molecular organic material, be to contain in the structure of molecule-polymeric compound of NHCOO-unit, its wear-resisting property is good, under same rigidity, than the elastomer bearing capacity height of other foamed material, the impact resistance height, the resilience scope is wide, therefore, it can be used as a kind of material of good supporting bearing structure.Owing in the middle of the packed layer material many gaps are arranged, therefore, when being subjected to external impacts, slight deformation takes place between each site, can cushion most power.Simultaneously, this material has certain Memorability, finds that soft chain segment has formed the crystallization that stress caused under the fiber extended configuration in the diffraction experiment of X-ray
The district is because the enhancing of structure causes rigidity and the intensity of fiber under extended configuration all to increase.When external force is removed, bounce back at once, the crystallization of soft chain segment disappears, and molecule returns rolled state again just can recover original outward appearance in the short time.
Polyurethane is stablized down at 140 ℃, the influence that not corroded by ozone, radiation hardness, antifungi, low friction.The strength ratio natural timber height of polyurethane, since middle gapped, so density is than the low (300～700kg/m of natural timber
3), reliable assurance has been arranged on the intensity, make him lighter again simultaneously than similar quality of materials, transportation is more convenient with installation.Since can with timber, metal and most of plastic bonding, adhesive ability is very strong, therefore, can be combined as a whole with the support tubes of inside and outside protective coating, when the outside when body applies active force, as the packed layer of bearing structure can be used as again to inside and outside two-part carry out strong fastening.But also having molding and processing cost is low, oil resistant, fat and chemical product are difficult for advantages such as contaminations, because polyurethane plasticity is more intense, manually and the cost of material very economical, reuse after can also reclaiming.
The outside of pipe for supporting of the present invention is a protective coating, and effect is a protection internal structure and handsome in appearance.Protective coating is selected a kind of polyethylene resin material for use, and polyethylene itself is a kind of degree of crystallinity height, nonpolar thermoplastic resin, odorless, nontoxic, the feel ceraceous has good resistance to low temperature (minimum serviceability temperature can reach 70～-100 ℃), and chemical stability is good, the erosion of the most of soda acids of ability, be insoluble to common solvent under the normal temperature, moisture absorption is little, and electrical insulation capability is good, still a kind of environmental protection recycled materials is free from environmental pollution; And general in the market modified poly ethylene or have only the characteristics of fire-retardant or antiultraviolet, and in order to adapt to specific use, modified polyethylene has not only had the function of antiultraviolet, slowed down the aging of it, had fire-retardant function simultaneously, arrived the standard of UL-94, used safer.Because this material is more convenient on the process of surface treatment with respect to ferrous materials, reduce surperficial plastic-blasting and be coated with technology, more environmental protection, and also by the mold injection typing, the cost aspect plastotype is more cheap, and efficient is higher.Than common steel pipe tubing, pipe for supporting of the present invention not only material is light, convenient transportation is easy to installation and removal, and at fastness, good assurance is all arranged on the fireproof performance, and can not get rusty, even damaging appears in tubing, plastotype use once more after the protective resin layer of outside can also reclaim and pulverize, the supporting element of the inside also can be recycled, and has very strong advantage in the resource circulation utilization.Because middle and outside material all is an insulating material, therefore, better assurance is arranged on Electrical Safety.The combined structure of polyurethane and outermost resin also plays buffer function on the other hand, and the effect of protection personal safety can be used certain material mixture ratio simultaneously, by the size of impact force, sets the coefficient that fractures, and makes rammer or people avoid macrolesion.Therefore the present invention adopts special three-decker, by middle foam packed layer with inside and outside two-layer holding together, it is strong, easy for installation to have stable in properties, region and climate adaptability, save reclaiming material, environmental protection more, advantage such as attractive in appearance, safe, can be used for various tubing support tubes, support with bar technical fields such as (bus stop strut, awning support and use bar) as lamp stand, flagpole, monitoring bar, communication bar, small building.
