Fasteners, txawm tias lawv qhov me me, ua haujlwm tseem ceeb heev - txuas ntau yam qauv, cov khoom siv thiab cov khoom siv.Lawv siv nyob rau hauv lub neej txhua hnub thiab kev lag luam, hauv kev tu thiab kev tsim ua haujlwm. Muaj ntau yam fasteners muaj nyob rau hauv kev ua lag luam. txiav txim kom tsis txhob xaiv qhov tsis ncaj ncees lawm, koj yuav tsum paub ntau yam ntawm cov khoom no thiab lawv cov yam ntxwv tseem ceeb.
Muaj ntau txoj hauv kev los faib cov fasteners.Ib tug ntawm lawv siv lub hav zoov ntawm threads.Nrog nws cov kev pab, koj muaj peev xwm tsim detachable kev twb kev txuas, uas yog nrov heev nyob rau hauv lub neej txhua hnub thiab muaj chaw.Nrov threaded fasteners muaj xws li: Txhua lub caij muaj lub hom phiaj tshwj xeeb. Piv txwv li, hauv Bulat-Metal koj tuaj yeem pom cov mounts rau cov haujlwm sib txawv.Hex bolts yog qhov zoo tagnrho rau kev koom nrog cov qauv hlau thiab cov khoom siv, nrog rau tus kheej tapping screws - rau kev kho cov haujlwm uas muaj cov khoom ntoo.Qhov kev khiav hauj lwm ntau ntawm cov stent txiav txim siab nws. cov duab, qhov loj me, cov khoom siv thiab lwm yam tsis muaj.Cov ntsia hlau ntawm cov ntoo thiab hlau yog qhov pom kev sib txawv - tus qub muaj cov xov nyias nyias thiab qhov sib txawv ntawm lub hau.
Hauv kev tsim kho kev lag luam, bolts thiab txiv ntseej yog siv dav hauv kev tsim cov tsev, txuas hniav, dams thiab fais fab nroj tsuag.Qhov tseeb, kev siv cov bolts thiab txiv ntseej yog ua los ntawm kev sib txuas ntawm cov hlau, uas txhais tau tias yog cov qauv bolts lossis arc vuam. siv cov electrodes, nyob ntawm qhov xav tau los koom nrog cov phaj steel thiab beam.Txhua txoj kev sib txuas muaj nws qhov zoo thiab qhov tsis zoo.
Structures screws siv nyob rau hauv lub tsev beam kev sib txuas yog ua los ntawm high-qib steel, feem ntau yog qib 10.9.Grade 10.9 txhais tau hais tias lub tensile lub zog ceev ntawm cov qauv ntsia hlau yog hais txog 1040 N / mm2, thiab nws muaj peev xwm tiv taus mus txog 90% ntawm tag nrho cov kev ntxhov siab. Siv rau cov ntsia hlau lub cev nyob rau hauv lub elastic cheeb tsam tsis tas yuav deformation.Piv nrog 4.8 hlau, 5.6 hlau, 8.8 qhuav steel, structural screws muaj zog tensile ntau zog thiab muaj ntau nyuaj thaum tshav kub kub kho nyob rau hauv ntau lawm.
