Ziziphi iibholithi eziphezulu?
Iibholiti ezenziwe ngentsimbi ephezulu okanye ezifuna ukulayishwa kwangaphambili okubalulekileyo zingabhekiswa njengeebholiti eziphezulu. Izikrufu eziphezulu zokuthumela zisetyenziswa ngokuqhelekileyo ukudibanisa iibhulorho, iintsimbi zentsimbi, izixhobo zombane eziphezulu kunye ne-ultra-high. Ukwaphuka kolu hlobo lwebholiti ubukhulu becala buba brittle. Izikrufu zamandla aphezulu ezifakwe kwisixhobo soxinzelelo oluphezulu kakhulu zifuna ucinezelo olubalulekileyo ukuqinisekisa ukutywinwa kwesikhongozeli.
Umahluko phakathi kweebholiti zokuqina okuphezulu kunye neebholiti eziqhelekileyo:
1. Umahluko kwimathiriyeli ekrwada
Iibholiti zamandla aphezulu zenziwe ngezinto eziphezulu zamandla. Izikrufu, amandongomane, kunye ne washers of high-high-strey bolts zonke zenziwe ngentsimbi yokuqina okuphezulu, eqhele ukusetyenziswa kwi 45 # steel, 40 boron steel, kunye ne 20 manganese steel. Iibholiti eziqhelekileyo zenziwe ngentsimbi eqhelekileyo ye-carbon structural ngaphandle konyango lobushushu.
2. Umahluko kumanqanaba amandla
Ukusetyenziswa kwee-bolts eziphakamileyo eziphezulu kuya kusasazeka ngokubanzi, kunye namanqanaba amabini amandla asetyenziswa ngokuqhelekileyo: i-8.8s kunye ne-10.9s, kunye ne-10.9 ininzi. Inqanaba lamandla eebholiti eziqhelekileyo kufuneka libe ngaphantsi, ngokubanzi 4.4, 4.8, 5.6, kunye ne-8.8 amanqanaba.
3. Umahluko kwiimpawu zamandla
Ukudityaniswa kwebholiti eqhelekileyo kuxhomekeke ekuxhathiseni kwe-shear yentonga yebholiti kunye noxinzelelo oluthwele amandla odonga lomngxuma ukuhambisa amandla okucheba, ngelixa iibholiti eziphakamileyo azinamandla aphezulu kuphela, kodwa zikwasebenzisa amandla amakhulu oxinzelelo lwangaphambili kwiibholiti, kubangela uxinzelelo olulawulwayo phakathi kwamacandelo adibanisayo, kwaye ngaloo ndlela kudala amandla amakhulu okukhuhlana kwe-perpendicular ukuya kwi-screw direction.
4. Umahluko ekusebenziseni
Ukudityaniswa kwe-bolted yamacandelo aphambili ezakhiwo zokwakha ngokuqhelekileyo zenziwe ngeebholiti eziphezulu. Iibholiti eziqhelekileyo zingaphinda zisetyenziswe, ngelixa iibholiti eziphezulu zingenakuphinda zisetyenziswe. Iibholiti zamandla aphezulu zisetyenziswa ngokubanzi kunxibelelwano olusisigxina.
