Kev lag luam screws yog tsim nyob rau hauv ntau yam duab thiab cov qauv.Steel alloys muaj lub peev xwm los ncua kev ntxhov siab heev nyob rau hauv kev cuam tshuam ntawm kev kho cua sov, ua rau cov kev xaiv ntawm no alloy thaum tsim steel bolts siv nyob rau hauv industrial lug. Ferroalloy steels muaj ib tug nruab nrab. Cov pa roj carbon ntau thiab cov khoom muaj zog ntau dua li cov hlau ntshiab, uas yog mos heev. Tau kawg, ntxiv rau cov pa roj carbon monoxide, stabilizing cov ntsiab lus xws li manganese, silicon, sulfur, phosphorus, thiab qee zaum txawm tias vanadium (vanadium ntxiv rau cov hlau sib txuas uas xav tau elasticity) muaj nyob rau hauv steel compounds.
Hauv kev tsim kho kev lag luam, bolts thiab txiv ntseej yog siv los ua ntau yam hauv kev tsim cov vov tsev, txuas hniav, dams thiab fais fab nroj tsuag.Qhov tseeb, kev siv cov qauv bolts thiab txiv ntseej yog ua los ntawm kev sib txuas ntawm cov hlau, uas txhais tau hais tias yog cov qauv bolts. los yog arc vuam siv electrodes, nyob ntawm seb qhov yuav tsum tau koom nrog steel phaj thiab beam.Txhua txoj kev sib txuas muaj nws tus kheej zoo thiab qhov tsis zoo, uas peb yuav tshuaj xyuas hauv qab no.
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 steel.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 hauv thaj tsam elastic tsis tas yuav deformation.Piv nrog 4.8 hlau, 5.6 hlau, 8.8 qhuav hlau, cov qauv ntsia hlau muaj zog tensile ntau dua thiab muaj kev kho cua sov ntau dua hauv kev tsim khoom.
Sib txawv ntawm tus qauv txheem hexagon bolts thiab ceev, tus qauv hexagon bolts thiab txiv ntseej yog tsim raws li DIN931 tus qauv raws li ib nrab lub zog, raws li DIN933 tus qauv raws li tag nrho cov zog, thiab hexagonal screws yog yooj yim, feem ntau ua raws li DIN6914 tus qauv.Coupling ceev ntawm Cov qauv ntsia hlau kuj muaj cov nqaij thiab qhov siab ntau dua li cov qauv hex ceev ua rau DIN934, nthuav tawm kev ntxhov siab ntau dua, ua rau DIN6915.Cov ntsia hlau ntawm qhov kev tsim kho no tau cim 10HV thiab feem ntau yog matt dub phosphating rau kev txhim kho ib puag ncig xeb los yog kub dip galvanized lossis tob. chrome matt nyiaj, ob qho tib si nrog cov hlau ua tiav.Lawv siv zinc thiab muaj kev tiv thaiv ib puag ncig zoo.
