Qhov ntau ntawm cov vojvoog muaj zog yuav tsum tau muab xam raws li txoj hauv kev tsim ntawm qhov tsim, thiab yuav tsum suav raws li qhov ntev. Tus naj npawb ntawm qhov yuav tsum tau muaj raws li qhov kev tsim kho, qhov faib ntawm qhov chaw tsim kho, kev ua haujlwm zoo ntawm cov khoom, thiab kev thauj mus los, kev txuag thiab kev thauj mus los ntawm lub tsev kawm ntawv, thiab engineering nyuaj Qhov cuam tshuam xws li kev siv nyiaj qhov 2-5% poob, kev yuav khoom.
Cov cuaj luaj siab siv rau kev tsim kho yuav tsum ua kom tau raws li "Large Hexagonal Bolts for Steel Structures" (GB1228), "Hom Ntsuas thiab Ntev ntawm Cov Txuas Siv Siab Rau Cov Khoom Hlau" (GB1229), "Loj Hexagonal Bolts rau Cov Qauv Hlau, Loj Hexagonal Ceev, thiab Txuas ". (GB1231), Torsion-type high-strength bolted joints rau steel qauv (GB3632), Cov Kev Qhia Kom Paub Rau Torsion Hom High-Zog Bolts rau Cov Qauv Hlau (GB3633) thiab lwm yam kev kawm.
Lub qhov fais fab sib txuas yuav tsum raug xa rov qab tom qab cov kev kuaj nram qab no ua tau raws li cov lus qhia:
1) Cov khoom siv, cov khoom tooj, cov khoom siv tshuaj thiab cov khoom siv ntawm cov khoom muaj tseeb los kuaj.
2) Npoo kev ntsuas ntawm kev xo.
3) Guaranteed load ntsuas ntawm cov txiv ntoo.
4) Hardness test of wash thiab washers.
5) Lub coupling torque coefficient test (qhia seb qhov ntsuas kub li cas). Nruab nrab thiab tus qauv hloov ntawm cov coefficients rau cov neeg loj taub hau txuas; nruab nrab qhov tseem ceeb ntawm zawm quab yuam axial thiab coefficient ntawm variation rau torsional shear connectors.
6) Ntsig axial force coefficient kuaj.
7) Yam khoom, ntau npaum li cas, hnub tim, pob khoom sau.
