Iimveliso

Isikrufu sehexagon yangaphandle lindongomane elihambelanayo elisetyenziselwa ukubopha kunye nokudibanisa iindawo ezimbini ezidibeneyo kunye nemingxuma kunye namalungu. Izikrufu zentloko zeHex ziqhele ukusetyenziswa iibholiti. Kubaluleke ngakumbi ukusebenzisa iKlasi A kunye neKlasi B elingaphandle elineheksagoni. Ukongezelela, isoloko isetyenziswa kwimeko yokuchaneka kwendibano ephezulu, impembelelo enkulu, ukungcangcazela okanye umthwalo wokuwela. Izikhonkwane zeBakala C zangaphandle ze-66 zisetyenziswa kwiimeko apho umphezulu unzima kwaye ukuchaneka kwendibano kungadingeki.

Esona sicelo siphambili se-steel structure bolt nut sikwisakhiwo sentsimbi yeprojekthi yobunjineli ukudibanisa iindawo zentsimbi yesakhiwo sentsimbi eshinyeneyo. Iimpawu ezingcono zokuqinisa, ezisetyenziselwa isakhiwo sensimbi kunye neeprojekthi zobunjineli, umphumo wokukhawuleza. Kwisakhiwo sesinyithi esiqhelekileyo, iibholiti zensimbi ezifunekayo zingaphezulu kwe-8.8 grade, kukho kwakhona i-10.9,12.9.

Rhoqo ngonyaka, icandelo loomatshini laseTshayina lifumana ilahleko efikelela kwiibhiliyoni zeeyuan kwiindawo zikawonke-wonke, kwipropathi, kunye nokhuseleko lomntu ngenxa yoqhagamshelo okanye ubusela babantu kunye nomonakalo, onempembelelo enkulu ekusebenzeni okunempilo koqoqosho lwelizwe. I-nati yokulwa nobusela yenziwe kwinqanaba elinye kunye ne-pier ebandayo kwaye ayifuni ukuqhutyelwa kwesibini.

Isakhiwo sensimbi i-torsion shear bolt yibholithi ephezulu yamandla kwaye luhlobo lwecandelo eliqhelekileyo. Iibholithi zentsimbi zohlulwe zibe ziibholiti zokuqina okuphezulu kwe-torsion shear kunye neebholithi ezinkulu ezinehexagonal zokuqina okuphezulu. Iibholiti ezinkulu ezinamacala amathandathu aphezulu zezenqanaba eliphezulu le-screws eqhelekileyo, ngelixa iibholiti ze-torsion shear ezomeleleyo luhlobo oluphuculweyo lweebholiti ezinkulu ezine-hexagonal zokuqina kokwakhiwa okungcono. Ibholithi enkulu yolwakhiwo lwentsimbi enehexagonal ibandakanya ibhawuthi enye, indongomane enye, kunye neewasha ezimbini. Iibholithi zolwakhiwo lwentsimbi yokucheba i-twist ziquka ibholithi enye, i-nati enye, kunye newasha enye. Kwizakhiwo zetsimbi eziqhelekileyo, iibholiti zentsimbi ezifunekayo zibakala 8.8 okanye ngaphezulu, kunye nemigangatho ye-10.9 kunye ne-12.9, zonke ziyi-high-high-high-high-high-high-high-sight-best-structural bolts. Ngamanye amaxesha, iibholithi kwizakhiwo zetsimbi azifuni i-electroplating.
