Yuav kom pab tau tus builder: qhov nyhav thiab qhov luaj li cas ntawm ib qho kuv-beam

Ib qho ntawm feem nrov hom hlau yog ib tug nqaj-zoo li tus ntoo khaub lig-sectional double-tog tsab ntawv T. I-beam loj nyob ntawm nws lub hom phiaj thiab yog hom twg los ntawm plaub mus rau 12 meters.

Nqaj double-tee: Hom

Hom ntawm profiles sib cais rau hauv tib yam thiab tshwj xeeb tsim los rau cov lag luam nyob rau hauv cov kev mob (rau monorails ntaus qhov cuab lub zog ncej). Nyob rau qhov ntev ntawm lub profile yuav ua tau seem, ntau seem, volumetric los yog ntau ntawm qhov seem nrog (5% batch nyhav), thiab lub off-gage. Direct daws teeb meem I-beam sau raws nkaus Ii qhov kev ncua deb ntawm ib tug txheej ntug mus rau lwm yam txee.

I-beams, nyob ntawm seb lub hom muaj teeb meem loj sib txawv nyob rau hauv loj. Piv txwv li, lub thickness ntawm lub txee yog nce mus nce los, vim nws yog ncaj qha mus txog rau nws cov zoo (inclined los yog thaum uas tig mus ib sab). Tsis tas li ntawd, I-beams yog distinguished los ntawm cov ntaub ntawv los ntawm uas lawv ua, vim hais tias nws muaj feem xyuam rau lawv cov kev siv nyob rau hauv ntau qhov chaw (tshwj xeeb steel, carbon los yog tsawg hlau steel, yog nyias kub-kuav los tiag steel girders).

Standards rau I-beams

Muaj ntau ntau lees qauv uas koom ua ib lub qhov luaj li cas ntawm ib qho kuv-beam nyob rau cov qauv ntawm cov nws siv thiab ua thiab siv. Piv txwv li, nyob rau hauv kub kuav los tiag steel I-beams standard gauge saib manufactured los ntawm cov loj tsis - lub sij ntev ntawm tus ntoo khaub lig seem, cov kev faib ua feem ntawm 1 m siv qhov tseem ceeb ntawm nyiaj pab ntau tshaj loads nyob rau hauv axes.

By dov precision beam paub qhov txawv dab tsi (labelled B) los yog siab raug (labelled B).

Tej yam qauv tswj qhov ntev sib tov I-beams, nyob rau hauv uas lub rhawv ntsib thaum uas tig mus, kub kuav los tiag steel, tshwj xeeb hlau, lwm yam tshwj xeeb I-beams thiab I-beams yog ua los ntawm cov manufacturers specifications.

Nyob rau hauv txhua tus ntawm cov uas twb muaj lawm I-beam tswj ghosts teev loj (nws qhov siab, dav thiab nruab nrab thickness ntawm lub flange, cov phab ntsa thickness, lub radii ntawm curvature ntawm lub puab thiab muab cov txee), qhov loj ntawm linear 'meter' (kg) thiab tus naj npawb ntawm meters ib tonne ntawm I-kab teeb.

GOST yuav tsum mus rau lub I-beam 36

Piv txwv li, peb xav nyob rau hauv ob npaug rau-T-beam ntau thiab tsawg pab qhov twg cov qhua 8239-89 yog txiav txim. Drawings ntawm cov profiles no feem ntau yog muab standard thiab nqa ib tug ncauj lus kom ntxaws tom qab ntxiv, ua rau cov geometric qhov ntev ntawm lub beam. Lawv, nyob rau hauv lem, sib haum mus rau hauv lub cev yam ntxwv ntawm lub profile, tseem ceeb heev rau nws daim ntawv thov.

Tus txheem tshuaj tsis cov yam ntxwv ntawm no hom ntawm profile, uas yog txheej txheem rau ob qho tib si producers thiab cov neeg muas zaub. Yog li, kuv-beams 36. Lub qhov ntev: qhov siab - 36 cm, lub dav ntawm lub rhawv - 14.5 cm, cov phab ntsa thickness - 0,75 cm, qhov nruab nrab thickness ntawm lub txee - 12.3 hli, nyob rau lub puab pub muab kwv yees voos kheej-kheej yuav tsum tsis muaj ntau tshaj li 1.4 cm, pub muab kwv yees rhawv - 0.6 cm.

Tshwj xeeb hom M I-beams yog siv rau cov coj nyiaj siv ua haujlwm cranes thiab Hoists, txij thaum lub thickness ntawm lub rhawv tau ntau zog piv nrog rau cov pa.

Kuj pom tus qauv siv lub rooj, yuav meej paub tus luj ib 'meter' (kev nqus) ntawm I-beam 36, uas yog ib txwm ib yam thiab muaj nqi 48,6 kilograms.
