Kev ntseeg tau txhawb lug yuav muab I-beam

Kuv- hlau beams yog siv los ntawm yuav luag txhua txhua niaj hnub siv qhov chaw, ob qho tib si muaj thiab civil. Nrog ib tug kuj tsis tshua muaj kev nqus, lawv muaj lub siab load peev xwm rau lub deflection uas yuav zoo faib cov load rau hauv lub txhawb lug. Cov no raug ua los ntawm dov hlau cov khoom (hlau cov khoom, kub-dov ob npaug rau-tee beam) los yog vuam txoj kev. Lub sectional yog H-zoo li tus tsim ntawm cov phab ntsa thiab ob flanges perpendicular mus rau nws. Lub rhawv tej zaum yuav muaj ib tug nrog kev tsis ncaj ncees rau lub ntxiv amplification. Tej cov khoom uas haum rau qhov cuab lub zog nrog amplification shafts (series C nrog ib tug gradient ntawm 16%) thiab rau tshem tawm mounting paths (series ntawm M nrog ib tug nqes hav ntawm 12%).

Kuav los tiag double-tee beam kuj hu ua ib qho kuv-beam. Lub ntsiab daim ntaub ntawv ntawm cov hlau khoom - tsev cov plag tsev, choj Siv, tshem tawm txoj kev, tug ncej thiab txhua. Nyob ntawm seb lub hom phiaj ntawm lub tsev lug, steelI I-beam tej zaum yuav tom rau txawv workloads. Structurally, kuv-sections thiab txawv phab ntsa thickness ntawm lub txee, lub txee situated seb (lawv puab cov ntsej muag tej zaum yuav mus tib seem los yog muaj ib tug nqes hav). Tus nqi kuj muaj cov kev xaiv ntawm raug txoj kev, lub hom phiaj thiab kev tsis.

Steel beam double-tee tau nyob rau hauv kev ua raws cai nrog rau tsoom fwv tus qauv (GOST 8239 - 89, Standard 19425 - 74, GOST 26020 - 83 thiab lwm tus), thiab kuj nyob rau hauv raws li cov specifications ntawm lub chaw tsim tshuaj paus. Nyob rau hauv cov ntaub ntawv ntawm dov cov ntaub ntawv uas yog cov hlau yam ntxwv zoo tib yam zoo. Qhov no hlau qauv raws li ib tug muab ob npaug rau-tee beam ua los ntawm welded steel yam ntxwv uas tsis muaj-hlau rau welded lug.

Ob peb cov hom ntawm I-beams nrog thaum uas tig mus ib sab rhawv: dab tsi (B), kem (K), wide- (W), qub (SB), ib qho ntxiv series (L thiab LH). Ua double-tee beam rau cov qauv, nyob ntawm seb lub hom phiaj, muaj ib tug ntev ntawm ntawm 4 mus rau 12 m (nyob rau hauv daim ntawv cog lus nrog rau cov qhua tuaj noj mov - mus rau 24 m). Yuav ua tau siab (A) los yog dab tsi (B) dov raug.

Welded steel I-beams no yog ua los ntawm daim ntawv hlau nyob rau hauv ob peb ua sawv. Thawj tsim lub preform yuav tsum tau loj los ntawm slicing lawv los ntawm ib tug hlau, ces as ntug. Tua sawb crane yog pauv mus rau lub conveyor siv, crimped thiab hlab automatic installation. Ntxiv mus, cov khoom yog dov nyob rau hauv ib tug tshwj xeeb camp rau qhov kev tshem tawm uas tau tsis xws luag thiab ua los ntawm blasting cog rau tshem tej paug. Qhov zoo tshaj ntawm welded I-beam yuav tsum tau raws li cov uas yuav tsum tau ntawm GOST 23118-99 thiab GOST 26020-83 (los yog nws tsis yog sib tham ua ntej nrog tus neeg muas zaub).

I-beams pab kom mus txog 30% los pab txhawb load-tau cov kabmob lug raws li muab piv nrog rau cov kub ob txhais ceg. Yam ua ntej kev txiav txim beams ntau thiab tsawg pab ho thiaj li tus nqi ntawm cov pov tseg. Qhov tsis zoo muaj xws li cov I-beams yooj yim xeb hais tias tsis muaj kev tiv thaiv txheej, thiab qhov yuav tsum tau rau ib tug tshwj xeeb cov khoom, tsis muaj uas lawv yuav tsis tau kev txhawb.
