Iibholiti ezenziwe ngentsimbi ephezulu, okanye iibholiti ezifuna amandla amakhulu okulayisha kwangaphambili, zingabizwa ngokuba ziibholiti eziphezulu. Iibholiti zamandla aphezulu zisetyenziswa ngokubanzi ukudityaniswa kweeBridges, iileyili, uxinzelelo oluphezulu kunye nezixhobo zoxinzelelo oluphezulu. Ukwaphuka kweebholiti ezinjalo ikakhulu kukuqhekeka okunokonakala. Kwiibhotshi eziphezulu ezisetyenziselwa izixhobo zoxinzelelo lwe-ultrahigh, ukwenzela ukuba kuqinisekiswe ukutywinwa kwesitya, i-prestress enkulu iyadingeka.
Umahluko phakathi kweebholiti zokuqina okuphezulu kunye neebholiti eziqhelekileyo:
Izinto eziphathekayo zeebholiti eziqhelekileyo zenziwe nge-Q235 (okt A3).
Izinto eziphathekayo ze-bolts zamandla aphezulu yi-35 # yentsimbi okanye ezinye izinto ezisemgangathweni ophezulu, eziphathwa ngobushushu emva kokuba zenziwe ukuphucula amandla.
Umahluko phakathi kwezi zibini ngamandla ezinto eziphathekayo.
Kwimathiriyeli ekrwada:
Iibholiti zamandla aphezulu zenziwe ngezinto ezinamandla kakhulu. I-screw, i-nut kunye ne-washer ye-bolt ephezulu-yomelele yenziwe ngentsimbi ephezulu, esetyenziswa ngokuqhelekileyo i-45 steel, i-40 boron steel, i-20 manganese titanium boron steel, i-35CrMoA kunye nokunye. Iibholiti eziqhelekileyo zenziwe ngokuqhelekileyo ngentsimbi ye-Q235 (A3).
Ukusuka kwinqanaba lamandla:
Iibholiti eziphezulu zokuqina zisetyenziswa ngokuqhelekileyo kumabakala amabini anamandla e-8.8s kunye ne-10.9, apho i-10.9 ininzi. Ibanga lamandla ebholiti eliqhelekileyo lisezantsi, ngokubanzi 4.8, 5.6.
Ukususela kumbono weempawu zamandla: iibholiti eziphezulu zenza uxinzelelo lwangaphambili kunye nokudlulisa amandla angaphandle ngokungqubuzana. Uqhagamshelo lwebholiti oluqhelekileyo luxhomekeke kuxhathiso lwebholiti yokucheba kunye noxinzelelo lodonga lomngxuma ukuhambisa amandla okucheba, kunye nokuzenzisa okuveliswe xa kuqiniswa i-nut kuncinci, impembelelo yayo inokungahoywa, kunye nebholithi ephezulu yokongeza kumandla ayo aphezulu, nayo iyasebenza. a pretension enkulu kwibholiti, ukuze uxinzelelo extrusion phakathi kwamalungu adibanisayo, ukuze kubekho ingxabano enkulu perpendicular ukuya kwicala isikrufu. Ukongezelela, i-pretension, i-anti-slip coefficient kunye nohlobo lwentsimbi luchaphazela ngokuthe ngqo umthamo wokuthwala iibholiti eziphezulu.
Ngokweempawu zamandla, inokwahlulwa ibe luhlobo loxinzelelo kunye nohlobo lokukhuhlana. Ezi ndlela zimbini zokubala zahlukile. Ubuncinci benkcazo ye-bolts high-high-power yi-M12, esetyenziswa ngokuqhelekileyo i-M16 ~ M30, ukusebenza kwee-bolts ezigqithisiweyo azinzile, kwaye kufuneka zisetyenziswe ngokucophelela ekuyilweni.
Ukusuka kwindawo yokusetyenziswa:
Ukudityaniswa kwebholidi yamacandelo aphambili esakhiwo sokwakha ngokuqhelekileyo kudityaniswe ngamabholiti aphezulu. Iibholiti eziqhelekileyo zingaphinda zisetyenziswe, iibholiti eziphakamileyo azikwazi ukuphinda zisetyenziswe. Iibholiti zamandla aphezulu zisetyenziswa ngokubanzi kunxibelelwano olusisigxina.
