Scaffolding Cov khoom siv txheem, vim li cas peb xaiv Q355.

Ntau tus neeg muas zaub nug kuv txog qhov khoom ntawm tus txuj, thiab ntau tus phooj ywg uas yuav lub ringlock scaffolding tsis paub yog vim li cas peb siv Q355 (Q345) hauv kev xaiv ntawm cov khoom ntawm tus qauv, kuj tseem muaj ntau cov qauv nrog Q355 steel ntawv kos ua lag luam, tab sis sib xyaw nrog cov khoom siv Q235. Rau qhov tshwm sim saum toj no, pebCeev ceev Scaffolding (Engineering) Co., Ltd., raws li tus thawj editor ntawm "Suav scaffold kev nyab xeeb kev qhia tshwj xeeb", yuav muab koj cov kev soj ntsuam los ntawm kev tsim kho kev tsim, kom piav qhia txog cov teeb meem ntawm "Q235 cov qauv ntaub ntawv"!

Ua ntej tshaj plaws, cia kuv piav qhia seb Q355 thiab Q235 txhais li cas.

Q345 (Q355) yog ib hom hlau, tsis tshua muaj lub zog hlau.Widely siv nyob rau hauv Txuas hniav, tsheb, nkoj, vaj tse, siab hlab ntsha, khoom siv tshwj xeeb, thiab lwm yam. "Q" txhais tau tias ua kom muaj zog, thiab 345 txhais tau tias lub zog tawm ntawm cov hlau no yog 345MPa.

Q235 cov pa roj carbon zoo tib yam txheej txheem steel tseem hu ua A3 steel.Common carbon cov txheej txheem steel-tiaj phaj yog hom steel khoom.Q sawv cev rau cov khoom xa tawm ntawm cov khoom zoo li no, thiab 235 nyob sab nraub qaum yog hais txog qhov txiaj ntsig ntawm cov khoom zoo no cov khoom siv, uas yog kwv yees 235MPa.

Yog hais tias cov khoom txheem ntawm lub nplhaib ntiv nplhaib ntsuas scaffolding yog Q235, cov kabmob muaj peev xwm ntawm nws tsuas yog 87% ntawm Q355.Qhov cov kabmob muaj peev xwm ntawm cov qauv yog feem ntau 90% ntawm cov peev txheej pub tau, uas yog 47.4kN. Yog tias cov khoom ntawm tus qauv tau hloov mus rau Q235, tus qauv tsim / qhov tso cai muaj peev xwm ntawm tus qauv yog = 47.4 / 46.1 = 103%, uas tshaj qhov tso cai muaj peev xwm muaj peev xwm thiab muaj kev phom sij muaj kev phom sij.

Raws li peb txhua tus paub, scaffolding engineering belongs rau ib qho ntawm kaum qhov tseem ceeb ntawm kev phom sij hauv kev tsim kho engineering, thiab tus qauv yog qhov tseem ceeb tshaj plaws qws ntaus nrig hauv lub nplhaib ntiv nplhaib scaffolding system, yog li hauv kev xaiv cov khoom siv, peb yuav tsum nruj soj ntsuam!
