H-beam daim ntawv thov nta
Qhov kub- dov H-beam steel tsim nyog faib qhov siab- rau- dav piv ntawm tus ntoo khaub lig-sectional loj raws li kev siv sib txawv, thiab muaj cov cuab yeej zoo heev thiab kev ua haujlwm zoo dua.
Tus qauv tsim yog hloov tau thiab muaj ntau haiv neeg. Nrog tib lub nqaj qhov siab, steel bay tuaj yeem ncav cuag 50% loj dua li cov pob zeb ua vaj tse, ua rau lub tsev layout hloov tau yooj yim.
Cov qauv yog lub teeb yuag. Piv nrog rau tus kheej - hnyav ntawm cov qauv pob zeb, nws yog sib dua, thiab txo tus kheej ntawm tus kheej - hnyav ntawm cov qauv txo lub zog sab hauv ntawm cov qauv tsim, uas tuaj yeem ua rau lub hauv paus kev kho mob ntawm cov qauv hauv tsev qis, kev tsim kho yooj yim, thiab tus nqi txo.
Cov qauv steel raws li kub-rolled H-beam muaj cov qauv kev tshawb fawb thiab tsim nyog, zoo plasticity thiab saj zawg zog, siab structural stability, thiab yog haum rau lub tsev cov qauv uas dais loj kev co thiab cuam tshuam loads, thiab muaj zog muaj peev xwm tiv thaiv tej yam ntuj tso kev puas tsuaj, tshwj xeeb tshaj yog haum rau tej lub tsev nrog ntau yam seismic zones. Raws li kev txheeb cais, nyob rau hauv lub ntiaj teb no kev puas tsuaj av qeeg loj tshaj 7 qhov chaw, cov steel qauv vaj tse dominated los ntawm H-beam yog qhov tsawg tshaj plaws puas.
Ua kom cov cheeb tsam siv tau zoo ntawm cov qauv. Piv nrog rau cov qauv pob zeb, tus ntoo khaub lig- ntu ntu ntawm cov qauv steel kem me me, uas tuaj yeem ua rau thaj chaw siv tau zoo ntawm lub tsev, thiab tuaj yeem ua rau thaj chaw siv tau zoo los ntawm 4-6% nyob ntawm ntau hom ntawm lub tsev.
Piv nrog welded H-beam, nws tuaj yeem txuag tau ntau yam haujlwm thiab cov ntaub ntawv, txo cov khoom siv raw, lub zog thiab kev ua haujlwm, muaj kev ntxhov siab tsawg, thiab muaj qhov zoo nkauj thiab zoo.
Nws yog ib qho yooj yim rau tshuab, structurally txuas thiab nruab, thiab tseem yooj yim rau dismantle thiab rov siv dua.
Kev siv H-beam tuaj yeem tiv thaiv ib puag ncig zoo, uas tau tshwm sim hauv peb yam: ua ntej, piv nrog cov pob zeb, kev tsim kho qhuav tuaj yeem raug saws, uas ua rau muaj suab nrov tsawg thiab tsis muaj plua plav; Thib ob, vim qhov txo qis ntawm nws tus kheej qhov hnyav, cov av tau txais los ntawm kev tsim kho hauv paus yog me me, thiab kev puas tsuaj rau cov khoom siv hauv av yog me me, ntxiv rau, cov pob zeb loj heev txo qis, thiab qhov kev khawb tau txo qis, uas yog qhov zoo rau kev tiv thaiv ib puag ncig ecological; thib peb, tom qab lub neej kev pab cuam ntawm lub tsev qauv tas sij hawm, tom qab cov qauv yog demolished, tus nqi ntawm cov khoom pov tseg generated yog me me, thiab cov nqi ntawm cov khoom seem ntawm cov khoom siv rov ua dua yog siab.
Cov qauv steel raws li kub-rolled H-beam muaj qib siab ntawm kev tsim khoom, uas yooj yim rau kev tsim cov tshuab, siv ntau lawm, siab precision, yooj yim installation, yooj yim los xyuas kom meej zoo, thiab tuaj yeem ua rau hauv tsev tsim khoom tiag tiag, choj tsim cov chaw tsim khoom, cov chaw tsim khoom cog cog, thiab lwm yam.
Kev tsim kho ntawm qhov project nrawm nrawm, thaj chaw me me, thiab nws haum rau txhua yam - huab cua kev tsim kho, thiab tsis tshua muaj kev cuam tshuam los ntawm huab cua. Kev tsim kho ceev ntawm cov qauv hlau ua los ntawm kub- dov H-beam yog li 2-3 npaug ntawm cov qauv pob zeb, thiab cov peev nyiaj tau los yog ob npaug, txo cov nqi nyiaj txiag, yog li txuag peev. Ua piv txwv "Jin Mao Tower" nyob rau hauv Pudong, Shanghai, Tuam Tshoj ua piv txwv, lub cev tseem ceeb ntawm cov qauv nrog qhov siab ntawm ze li ntawm 400 m tau capped nyob rau hauv tsawg tshaj li ib nrab xyoo, thaum lub steel-pob zeb qauv siv ob xyoos los ua kom tiav.
Lub kaum sab xis steel daim ntawv thov cov yam ntxwv
Lub kaum sab xis steel: feem ntau hu ua lub kaum sab xis hlau, yog ib txoj hlua ntev ntawm cov hlau nrog ob sab perpendicular rau ib leeg. Muaj lub kaum sab xis steel thiab lub kaum sab xis tsis sib xws. Cov ces kaum sib npaug muaj ob qhov dav dav sib npaug, thiab lawv cov kev qhia tshwj xeeb tau qhia hauv millimeters ntawm sab dav × sab dav × sab thickness. Piv txwv li, "∠30 × 30 × 3", uas txhais tau hais tias sab dav yog 30 hli thiab sab thickness yog 3 hli. Nws kuj tseem tuaj yeem qhia tau los ntawm tus qauv naj npawb, uas yog tus lej ntawm centimeters ntawm sab dav, xws li ∠3 #. Tus qauv tsis sawv cev rau qhov loj ntawm qhov sib txawv ntawm cov thicknesses nyob rau hauv tib tus qauv, yog li sab dav thiab sab thickness ntawm lub kaum sab xis steel yuav tsum tau sau rau hauv daim ntawv cog lus thiab lwm cov ntaub ntawv kom tsis txhob raug sawv cev los ntawm tus qauv ib leeg. Cov specifications ntawm kub - dov equilateral lub kaum sab xis steel yog 2#-20#. Lub kaum sab xis steel tuaj yeem tsim los ntawm ntau yam kev ntxhov siab sib txawv raws li qhov sib txawv ntawm cov kev xav tau ntawm cov qauv, thiab tuaj yeem siv los ua qhov sib txuas ntawm cov khoom. Nws yog dav siv nyob rau hauv ntau lub tsev tsim thiab engineering, xws li lub tsev kab teeb, txuas hniav, kis tau tus mob yees, nqa thiab tsheb thauj mus los machinery, ships, industrial furnaces, tshuaj tiv thaiv yees, thawv racks thiab warehouse txee.
Channel steel daim ntawv thov yam ntxwv
Channel steel yog ib txoj hlua ntev ntawm cov hlau nrog ib tug grooved cross-section. Nws cov qauv kev qhia tshwj xeeb, xws li 120 * 53 * 5, uas yog, lub duav siab ntawm 120 hli, ceg dav ntawm 53 hli, lub duav tuab ntawm 5 hli ntawm channel steel, lossis 12 # channel steel. Channel steel nrog tib lub duav siab, yog tias muaj ob peb ceg dav dav thiab lub duav tuab, nws tseem yuav tsum tau ntxiv abc ntawm sab xis ntawm tus qauv kom paub qhov txawv, xws li 25A# 25B# 25C# thiab lwm yam. Channel steel yog muab faib ua tib yam channel steel thiab lub teeb channel steel. Qhov tshwj xeeb ntawm kub- dov zoo tib yam channel steel yog 5-40#. Cov lus qhia tshwj xeeb ntawm kub- dov hloov tau yooj yim channel steel muab los ntawm kev pom zoo ntawm cov khoom siv thiab cov neeg xav tau yog 6.5-30 #. Channel steel feem ntau yog siv hauv kev tsim vaj tsev, kev tsim tsheb thiab lwm yam kev lag luam, thiab cov hlau channel feem ntau yog siv ua ke nrog I-beams.
Kuv -beam daim ntawv thov yam ntxwv
I-beams, tseem hu ua steel beams, yog cov hlua ntev ntawm cov hlau nrog ib qho I-zoo li tus ntoo khaub lig-section. Nws cov specifications qhia nyob rau hauv millimeters ntawm duav qhov siab (h) * ceg dav (b) * duav thickness (d), xws li "ua hauj lwm 160 * 88 * 6", uas yog, lub duav siab yog 160 hli, ceg dav yog 88 hli, thiab lub duav thickness yog 6 hli. Cov kev qhia tshwj xeeb ntawm I-beams kuj tuaj yeem qhia los ntawm tus qauv, uas qhia cov naj npawb ntawm centimeters ntawm lub duav siab, xws li Gong 16#. Rau kuv -beams nrog tib lub duav qhov siab, yog tias muaj ob peb ceg dav dav thiab lub duav tuab, nws yuav tsum tau ntxiv abc ntawm sab xis ntawm tus qauv kom paub qhov txawv, xws li 32A# 32B# 32C# thiab lwm yam. Kuv-beams tau muab faib ua tej yam yooj yim I-beams thiab teeb kuv-beams, thiab cov specifications ntawm kub-rolled dog dig I-beams yog 10-63#. Cov lus qhia tshwj xeeb ntawm kub- dov zoo tib yam I- kab teeb muab los ntawm kev pom zoo ntawm cov khoom siv thiab kev xav tau yog 12-55 #. I-beams yog siv dav hauv ntau lub tsev tsim, txuas hniav, tsheb, brackets, machinery, thiab lwm yam.
Daim ntawv thov yam ntxwv ntawm txias- ua hlau
Txias- steel tsim yog cov khoom tseem ceeb rau kev ua lub teeb steel qauv, uas yog ua los ntawm steel phaj los yog steel strip txias forming. Nws cov phab ntsa tuab tuaj yeem tsis tsuas yog ua kom nyias nyias, tab sis kuj ua kom yooj yim rau cov txheej txheem ntau lawm thiab txhim kho kev tsim khoom. Nws tuaj yeem tsim ntau yam profiles thiab txias -them ntawm cov khoom sib txawv nrog cov phab ntsa tuab, tab sis txoj kev hla -sectional shapes uas nyuaj rau tsim los ntawm cov txheej txheem kub dov. Ntxiv rau kev siv ntau lub tsev tsim, txias- steel tsim kuj tau siv dav hauv kev tsim tsheb, kev tsim khoom siv tshuab ua liaj ua teb, thiab lwm yam.
Tshwj xeeb- cov hlau zoo li muaj xws li tuav cov nplhaib, cov hlau nplaum, cov hlau nplaum hlau, cov hlau nplaum nplaum, cov hlua khi cov hlau, cov hlua me me, T- zoo li cov hlau, cov pob tiaj tus hlau, cov ntaub npuag noj cov hlau, kub- dov hexagonal steels, thiab lwm yam. Tsis tas li ntawd, muaj rivet steel, qhov rai steel, thiab lwm yam.
