Cov khoom sib txawv
High-strength ntses bolts, tsim rau superior load-bearing muaj peev xwm, txawv ho los ntawm zoo tib yam ntses bolts, feem ntau yog ua los ntawm Q235 (A3) steel. Cov qub siv cov ntaub ntawv muaj zog xws li 45 steel, 40 boron steel, thiab 20 manganese titanium boron steel, thaum lub tom kawg tso siab rau Q235 steel.
Daim ntawv thov
High-strength ntses bolts, nrog rau qib zoo li 8.8s thiab 10.9s, siv pretension thiab kev sib txhuam rau kev quab yuam, tsis zoo li cov ntses bolts uas siv shear resistance. Qhov tseem ceeb, cov ntses ntses muaj zog, npaj rau kev sib txuas mus tas li, tsis tuaj yeem rov qab siv dua, qhov zoo tib yam ntses bolts tuaj yeem siv tau. Qhov zoo ntawm cov ntses bolts muaj zog muaj xws li kev tsim kho yooj yim, kev ua haujlwm zoo heev, kev tshem tawm, qaug zog tiv thaiv, thiab ruaj khov nyob rau hauv dynamic loads. Lawv yog pre-stressed siv ib tug tshwj xeeb ciaj ntswj los siv tswj pre-tension. Cov txheej txheem no yog txhawm rau txhim kho kev nkag siab thiab coj cov neeg siv kom paub qhov txawv ntawm cov ntses muaj zog ntawm cov khoom sib xws.
