Tsim ntawm I Section Steel

Cov qauv tsim ntawm I Section Steel, nrog rau cov khoom siv hauv kev tsim khoom, yog cov laj thawj tseem ceeb vim li cas lawv thiaj li muaj peev xwm tuav tau ntau qhov hnyav. Lub steel kuv beam yog tsim los ntawm ob lub dav hlau ntev hu ua flanges thiab ib feem nruab nrab hu ua lub vev xaib. Cov ntu ntu ntawm lub vev xaib thiab cov tub yees muaj qhov "I" thiab "H" zoo li vim yog cov duab ntawm lub vev xaib thiab flanges.

Nyob ntawm lawv cov kev siv, I Section Steel muaj nyob rau hauv ntau yam flange widths thiab web thicknesses. Cov axil fiber ntau, uas nqa cov nyhav feem ntau hauv I-beam, muaj cov khoom siv feem ntau. Cov duab ntawm I-beam yog qhov tseem ceeb hauv kev ua kom muaj zog tiv thaiv kev ntxhov siab.

Qhov zoo tshaj plaws I Section Steel muaj thaj tsam me me thiab siv cov khoom siv tsawg dua thaum tuav lawv cov duab npaj. Tus neeg cog lus yuav tsum xav txog ntau yam thaum xaiv I-beam, uas suav nrog:

Kev vibration

Qee qhov loj thiab rigidity raug xaiv los tiv thaiv kev co hauv pem teb.

Khoov

Ib qho I-beam's cross-section yuav tsum muaj zog txaus los tiv thaiv kev ntxhov siab.

Buckling

Cov flanges raug tiv thaiv kom tsis txhob shear hauv zos, los yog sab buckling.

Kev ntxhov siab

Tus neeg cog lus yuav tsum xaiv I-beam nrog lub web thickness uas tuaj yeem tiv taus kev ntxhov siab tsis muaj buckling lossis rippling.

Deflection

Txhawm rau tiv thaiv kev cuam tshuam, tus neeg cog lus yuav tsum siv lub I-beam tuab.

Yog vim li cas kuv Section Steel siv nyob rau hauv Steel Siv

Los ntawm Ntau Qhov Loj

I Section Steel yog universal beams thiab siv thoob ntiaj teb rau feem ntau steel tsim project. Nws tuaj nyob rau hauv ntau yam hnyav, seem qhov tob, web thickness, flange widths, thiab lwm yam specifications rau txawv hom phiaj. Nyob ntawm tus qauv ntawm I beam, nws yog siv rau ntau lub hom phiaj.

Dais siab dua Loads

Kev tsim ntawm I Section Steel ua rau nws muaj peev xwm khoov raws li kev ntxhov siab ntau es tsis txhob buckling. Raws li cov nqaj tau txais cov khoom thauj, lub zog raug xa mus rau perpendicularly, yog li txhawb nqa lwm cov tswv cuab ntawm cov kab teeb. Kuv beams feem ntau yog ua los ntawm steel, yog li ua kom muaj kev ncaj ncees ntawm cov qauv nrog lub zog tsis tu ncua thiab kev txhawb nqa. Kuv beam zog yog tsawg formidable nyob rau hauv lub transverse kev taw qhia thiab kuj adept ntawm nqa torsion. Cov hlau muaj cov khoom uas tso cai rau cov khoom hnyav hnyav ntawm cov qauv. Lub zog ntawm cov hlau thiab cov duab ntawm cov nqaj ob leeg tuaj yeem txo qhov kev xav tau los suav nrog ntau cov qauv kev txhawb nqa, txuag lub sijhawm thiab nyiaj txiag thiab ua rau cov qauv ruaj khov.

Nws muaj lub sijhawm siab ntawm Inertia

Qhov seem ntawm qhov nruab nrab ntawm lub nqaj, lossis qhov nruab nrab axis, tsis tiv thaiv kev khoov vim qhov sib txawv ntawm qhov hnyav ntawm lub nqaj. Vim qhov kev ncua deb ntawm flange thiab axis, kuv beams muaj lub sijhawm siab ntawm inertia. Qhov loj dua lub sij hawm ntawm inertia, qhov tsawg dua lub nqaj yuav khoov kom tiv thaiv lub sijhawm khoov. Kuv beams tuaj yeem dov, welded, extruded, thiab riveted ib yam nkaus vim cov cuab yeej no.

Pab hauv Fabrication

Hlau fabrication muaj kev txiav, dabtsi yog khoov, thiab shaping ntawm structural steel. I beams yog ntau yam thiab tuaj yeem siv tau rau hauv txhua qhov kev tsim kho steel. Kuv beam steel fabrication yog ceev, npaum, thiab pheej yig los ua kom tiav cov xaj thiab ua tau raws li qhov xav tau ntawm qhov project. Nrog rau kev paub zoo, kev paub dhau los, kev ua haujlwm nyuaj, thiab kev siv cov cuab yeej tshwj xeeb, nws yooj yim dua rau kev siv I beam thaum kev cai vuam txheej txheem thiab hlau fabrication rau txhua hom kev tsim kho.

Txo, rov siv dua, thiab rov ua dua tshiab

Kev tsim khoom ntawm I beams txhais tau tias tsawg kawg nkaus pov tseg thaum tsim kho. Muaj cov kev coj ua ntsuab hauv ntau lub teb chaws ua rau kuv beam pheej yig. Yuav luag ib nrab ntawm lub ntiaj teb cov hlau yog tsim nyob rau hauv hluav taws xob nroj tsuag kom tsis txhob muaj CO2 emissions. Cov khoom siv hlau tuaj yeem rov ua dua thiab rov ua dua yam tsis muaj kev cuam tshuam rau lawv lub zog. Txij li kuv cov kab hluav taws xob feem ntau yog ua los ntawm cov hlau, lawv tuaj yeem siv tau thiab rov siv tau ntau txoj hauv kev thiab tseem txo cov nqi. Recycling steel txuag lub zog sib npaug rau lub zog txog ntau lab tsev neeg rau ib xyoos.

Tiv thaiv kev vibration

Ib qho ntawm cov teeb meem loj thaum tsim lub tsev yog tsim kom muaj cov qauv nrog tsawg dua hauv pem teb kev co. Kev co hauv pem teb hauv cov tsev steel tuaj yeem tsim nrog ntau yam kev sib txuas ncaj qha thiab tsis ncaj qha ntawm kev co.

Qhov zoo ntawm I Section Steel

Dais siab dua Loads

Nws muaj lub sijhawm siab ntawm Inertia

Qhov seem ntawm qhov nruab nrab ntawm lub nqaj, lossis qhov nruab nrab axis, tsis tiv thaiv kev khoov vim yog qhov sib txawv ntawm qhov hnyav ntawm lub nqaj. Vim qhov kev ncua deb ntawm flange thiab axis, I-beams muaj lub sijhawm siab ntawm inertia.

Pab hauv Fabrication

Txo, rov siv dua, thiab rov ua dua tshiab

Kev tsim khoom ntawm I Section Steel txhais tau tias tsawg kawg nkaus pov tseg thaum tsim kho. Muaj cov kev coj ua ntsuab hauv ntau lub tebchaws ua rau I Section Steel pheej yig. Yuav luag ib nrab ntawm lub ntiaj teb cov hlau yog tsim nyob rau hauv hluav taws xob nroj tsuag kom tsis txhob muaj CO2 emissions. Cov khoom siv hlau tuaj yeem rov ua dua thiab rov ua dua yam tsis muaj kev cuam tshuam rau lawv lub zog.

Cov duab thiab cov qauv ntawm I Section Steel

I Section Steel muaj ob lub dav hlau kab rov tav, hu ua flanges, txuas los ntawm ib qho ntsug, lossis lub vev xaib. Cov duab ntawm flanges thiab lub vev xaib tsim ib qho "I" lossis "H" hla ntu. Feem ntau kuv beams siv cov qauv hlau, tab sis qee qhov yog ua los ntawm txhuas. Infra-hlau kev tsim kho, xws li carbon structural steel thiab high-strength low-alloy structural steel, muaj ntau yam kev siv - xws li lub tsev thav duab, txuas hniav, thiab cov hom phiaj dav dav.

I Section Steel tuaj nyob rau hauv ntau yam hnyav, seem qhov tob, flange widths, web thicknesses, thiab lwm yam specifications rau txawv hom phiaj. Thaum xaj I Section Steel, cov neeg yuav khoom faib lawv los ntawm lawv cov khoom thiab qhov ntev. Piv txwv li, 11x20 kuv beam yuav muaj qhov tob 11-inch thiab qhov hnyav ntawm 20 phaus ib ko taw. Cov neeg tsim khoom xaiv qhov loj me ntawm I Section Steel raws li qhov xav tau ntawm lub tsev tshwj xeeb. Ib tug builder yuav tsum coj ntau yam rau hauv tus account, xws li:

1 Deflection:Tus neeg tsim khoom yuav xaiv lub thickness kom txo qis deformation ntawm lub nqaj.

2. Kev vibration:Ib qho loj thiab nruj yog xaiv los tiv thaiv kev vibrations hauv lub tsev.

3. Khoov:Lub zog ntawm I beam's cross-section yuav tsum ua kom haum rau qhov kev ntxhov siab.

4. Kev sib tw:Cov flanges raug xaiv los tiv thaiv buckling hauv zos, sab sab, lossis torsionally.
