Ib yam nrov ntawm cov hlau dov yog cov nqaj, hauv ntu zoo ib yam li tsab ntawv ob sab T. Qhov loj ntawm I-beam nyob ntawm nws lub hom phiaj thiab txawv ntawm plaub mus rau 12 meters.
I-beam: views
Hom profiles tau muab faib ua qhov zoo tib yam thiab tshwj xeeb, tsim los ua haujlwm hauv cov xwm txheej tshwj xeeb (rau kev teeb tsa ntawm monorails, kev txhawb nqa ntawm kuv lub shafts). Nyob ntawm seb hom, qhov ntev ntawm qhov profile tuaj yeem ntsuas tau, ntau qhov ntsuas, ntsuas lossis ntau yam ntawm nws nrog cov seem (txog li 5% ntawm qhov loj ntawm cov batch), nrog rau tsis ntsuas. Qhov loj me tam sim no ntawm I-nqaj sib raug rau qhov kev ncua deb ntawm ib sab ntug ntawm lub txee mus rau lwm qhov.
I-nqaj, nyob ntawm hom, muaj qhov sib txawv loj ntawm qhov loj. Piv txwv li, qhov tuab ntawm flange yog qhov sib txawv vim nws ncaj qha ntsig txog nws cov duab (slanted lossis parallel). I-beams kuj txawv ntawm cov khoom uas lawv tau tsim, txij li thaum lawv siv rau cov los yogLwm yam khoom (los ntawm cov hlau tshwj xeeb, los ntawm cov pa roj carbon lossis cov hlau tsis tshua muaj hlau, cov kab hlau kub dov muaj nyias nyias).
Standards for I-beams
Muaj ntau ntau cov qauv lees paub uas sib koom ua ke ntawm qhov loj ntawm I-beam nyob ntawm txoj kev ntawm nws cov khoom siv thiab lub hom phiaj. Piv txwv li, tus txheej txheem rau kub-kuav los tiag steel I-beams tswj cov tsim assortment raws li lub ntsiab qhia - qhov tseeb qhov ntev, hla ntu, qhov hnyav ntawm 1 m, siv qhov tseem ceeb ntawm qhov siab tshaj plaws loads.
Raws li qhov tseeb ntawm dov, kab teeb zoo tib yam (nrog cim C) lossis nce qhov tseeb (kos B) yog qhov txawv.
Sib cais cov qauv tswj qhov ntev ntawm qhov ntau ntawm I-beams, nyob rau hauv uas cov npoo ntawm flanges yog parallel, kub-kuav los tiag steel, tshwj xeeb steel, lwm yam tshwj xeeb I-beams, thiab I-beams kuj. ua raws li cov specifications ntawm manufacturers.
Nyob rau hauv txhua qhov GOSTs uas twb muaj lawm, kev tswj qhov loj ntawm I-nqaj yog qhia (nws qhov siab, dav thiab nruab nrab tuab ntawm flange, phab ntsa thickness, radii ntawm curvature ntawm sab hauv thiab flange), qhov loj ntawm ib tug linear meter (kg) thiab tus naj npawb ntawm meters hauv ib tuj ntawm I-beams.
GOST cov cai rau I-beam 36
Piv txwv li, peb txaus siab rau I-nqaj, qhov ntev uas tau txiav txim los ntawm GOST 8239-89. Kev kos duab ntawm cov profiles no feem ntau yog muab los ntawm tus qauv thiab nqa cov ncauj lus kom ntxaws raws li cov duab geometric qhov ntev ntawm cov nqaj. Cov no, nyob rau hauv lem, sib haum mus rau lub cev yam ntxwv ntawm lub profile uas yog ib qho tseem ceeb rau nws daim ntawv thov.
In standardcov tsis muaj nyob rau hauv hom profile no tau sau tseg, uas yog siv rau ob qho tib si manufacturers thiab cov neeg yuav khoom. Yog li, I-beam 36. Dimensions: nyob rau hauv qhov siab - 36 cm, nyob rau hauv txee dav - 14.5 cm, nyob rau hauv phab ntsa thickness - 0.75 cm, nyob rau hauv nruab nrab txee thickness - 12.3 hli, thaum lub internal rounding yuav tsum muaj ib tug vojvoog ntawm tsis ntau tshaj 1.4 cm., txee puag ncig mus txog 0.6 cm.
Tshwj xeeb hom M I-nqaj yog siv rau kev taw qhia nyiaj siv ua haujlwm cranes thiab telphers, txij li cov tuab ntawm cov txee tau nce ntxiv rau qhov sib piv nrog cov niaj hnub.
Keem saib cov lus siv ntawm tus qauv, koj tuaj yeem pom qhov hnyav ntawm lub ntsuas ntsuas (qhov tshwj xeeb lub ntiajteb txawj nqus) ntawm I-beam 36, uas ib txwm zoo ib yam thiab hnyav txog 48.6 kg.
