Steel Structure Steel Xaiv, Peb Yuav Tsum Ua Dab Tsi?

1. Kev xaiv qib zoo
(1) Yog hais tias nws yog ib tug general non-welded steel qauv, ces qib A steel yuav raug xaiv.
(2) Yog hais tias nws yog welded steel qauv, thiab nws yog static load, ces qib B steel yuav tsum tau xaiv; Yog hais tias nws yog dynamic load, ces raws li ambient kub ntawm cov qauv, C, D los yog E qib steel qauv yuav tsum tau xaiv, los yog ntxiv qib steel. Nyob rau hauv txoj kev no, qhov hloov pauv kub ntawm cov hlau tuaj yeem qis dua qhov ntsuas kub ntawm cov qauv.
(3) Yog hais tias nws yog ib feem ntawm lub lamellar tearing quab yuam, thiab nws yog ib tug steel phaj nrog ib tug tuab tuab, nws yuav tsum muaj peev xwm tiv taus lamellar tearing.
(4) Rau cov qauv sib koom ua ke, lossis hnyav welded steel qauv nrog cov kev ntxhov siab nyuaj thiab kev ua haujlwm hnyav ib puag ncig, tus qauv yuav tsum tau ua kom zoo dua qub.
(5) Yog hais tias nws yog ib qho tseem ceeb steel qauv steel, ces kev xaiv ntawm nws cov qib zoo yuav tsum tau txhim kho.
2. Kev xaiv lub zog theem
(1) Yog hais tias nws yog ib tug zoo tib yam steel qauv steel, nws lub zog qib yog feem ntau xaiv Q235 los yog Q345.
(2) Yog tias nws hnyav lossis hnyav hlau qauv steel, ces nws qib zog yog Q345, Q390 lossis Q420, lossis qib siab dua.
(3) Yog tias nws yog A txias-tsim nyias-phab ntsa lub teeb steel qauv, ces koj tuaj yeem xaiv qib A thaum tsis siv vuam, thiab xaiv qib B thaum vuam.
