Hom thiab Parameters ntawm Steel Structure Bolts

Steel qauv boltyog ib hom kev muaj zog bolt. Steel structural bolts tseem hu ua high-strength bolts los yog high-strength bolt pob qij txha. Nws yog ib daim ntawv tshiab ntawm kev sib txuas tsim txij li xyoo 1950s. Nws yooj yim siv cov qauv steel bolts los txuas cov khub? Kev ua tau zoo zog? Thiab nws yog detachable? Qhov no yog ib txoj kev sib txuas zoo heev vim tias nws tiv taus kev qaug zog thiab yuav tsis xoob nyob rau hauv dynamic loads.

Steel qauvboltsyog cov bolts muaj zog thiab cov khoom siv txheem. Kev ua tau zoo fastening, siv hauv cov qauv steel thiab engineering kom ua tiav cov nyhuv fastening. Nyob rau hauv dav dav steel qauv, qhov yuav tsum tau steel qauv bolts yog tag nrho saum toj no 8.8, nrog 10.9 thiab 12.9, tag nrho cov uas yog high-strength steel qauv bolts. Qee zaum bolts ntawm cov qauv hlau tsis tas yuav plating. zoo txaus.

Thaum txhim kho steel qauv bolts, lub torque ciaj ntswj yog kom nruj cov neeg rau, uas ua rau cov steel qauv bolts muaj ib tug loj heev pretension, uas yuav tswj tau. Cov txiv ntoo thiab liner tsim tib qhov sib txhuam nrog cov tswv cuab ua ntej. Nyob rau hauv qhov kev txiav txim ntawm lub pretensioning quab yuam, ib tug kuj loj frictional quab yuam yog tsim nyob rau hauv lub nto ntawm lub connecting cov tswv cuab, uas yog obviously ntev npaum li cas lub zawv zawg quab yuam yog me dua lub frictional quab yuam. Kev quab yuam, tawg tawg txaus yuav tsis swb, qhov no yog txoj hauv kev sib txuas kom paub txog cov qauv steel bolts.

Bolts siv los txuas cov qauv hlau yog hu ua lub zog muaj zog bolts, suav nrog cov ntsia hlau, ntxhua khaub ncaws thiab txiv ntoo. High-strength bolts tau muab faib ua torsional shear type thiab loj hexagonal bolts. Thaum kawg, zawm lub torsional shear hom nrog rab phom torque, thiab twist lub hex loj nrog lub torque ciaj ntswj. High-strength bolts siv rau steel qauv kev sib txuas yuav tsum tau kuaj los ntawm ib tug thib peb tog ua ntej siv.
