Cov txiaj ntsig thiab cov yam ntxwv ntawm H beam yog dab tsi?

H beamyog siv dav hauv kev tsim kho hlau niaj hnub no. Qhov chaw ntawm H-section hlau tsis muaj qhov nkhaus, thiab qhov chaw sab saud thiab sab qis yog sib luag. Qhov seem ntawm H-beam zoo dua li cov qauv ib txwm muaj.Kuv - lub teeb, channel steel thiab Angle steel. Yog li cov yam ntxwv ntawm H beam yog dab tsi?

1. Lub zog ua haujlwm siab

Piv nrog rau I-beam, qhov seem modulus loj heev, thiab qhov xwm txheej ntawm kev coj tus kheej yog tib yam tib lub sijhawm, cov hlau tuaj yeem txuag tau 10-15%.

2. Tsim qauv yooj ywm thiab nplua nuj

Yog tias muaj tib lub qhov siab ntawm lub nqaj, cov qauv hlau loj dua 50% ntawm cov qauv pob zeb, ua rau qhov kev teeb tsa yooj ywm dua.

3. Lub teeb yuag ntawm cov qauv

Piv nrog rau cov qauv pob zeb ua vaj tse, qhov hnyav ntawm cov qauv yog sib dua, qhov txo qhov hnyav ntawm cov qauv, txo lub zog sab hauv ntawm kev tsim qauv, tuaj yeem ua rau cov kev xav tau ua tiav ntawm lub hauv paus ntawm cov qauv tsev tsawg, kev tsim kho yooj yim, thiab tus nqi raug txo qis.

4. Kev ruaj khov ntawm cov qauv siab

Lub H-beam kub dov yog lub qauv hlau tseem ceeb, nws cov qauv yog scientific thiab tsim nyog, zoo plasticity thiab yooj ywm, siab ruaj khov, tsim nyog rau kev co thiab cuam tshuam ntawm cov qauv tsev loj, muaj peev xwm tiv taus kev puas tsuaj ntuj tsim, tshwj xeeb tshaj yog haum rau qee cov qauv tsev hauv thaj chaw av qeeg. Raws li cov ntaub ntawv, hauv ntiaj teb ntawm qhov loj 7 lossis ntau dua qhov kev puas tsuaj av qeeg, H-puab hlau feem ntau yog cov qauv hlau tsev raug kev txom nyem tsawg tshaj plaws.

5. Ua kom thaj chaw siv tau zoo ntawm cov qauv

Piv nrog rau cov qauv pob zeb ua vaj tse, thaj tsam ntawm cov qauv hlau yog me me, uas tuaj yeem ua rau thaj chaw siv tau zoo ntawm lub tsev ntau dua, nyob ntawm ntau hom tsev sib txawv, tuaj yeem ua rau thaj chaw siv tau zoo dua ntawm 4-6%.

6. Txuag cov neeg ua haujlwm thiab cov ntaub ntawv

Piv nrog rau kev vuam H-beam hlau, nws tuaj yeem txuag tau cov neeg ua haujlwm thiab cov ntaub ntawv, txo kev siv cov khoom siv raw, lub zog thiab kev ua haujlwm, kev ntxhov siab tsawg, zoo nkauj thiab qhov zoo ntawm qhov chaw.

7. Yooj yim rau kev ua khoom siv kho tshuab

Yooj yim rau txuas thiab teeb tsa structurally, tab sis kuj yooj yim rau tshem tawm thiab rov siv dua.

8. Kev Tiv Thaiv Ib puag ncig

Kev siv ntawmHlau H-seemtuaj yeem tiv thaiv ib puag ncig tau zoo, uas pom tau hauv peb yam: thawj zaug, piv nrog cov pob zeb ua vaj tse, nws tuaj yeem siv kev tsim kho qhuav, ua rau muaj suab nrov tsawg dua thiab hmoov av tsawg dua; Qhov thib ob, vim yog qhov hnyav txo qis, kev rho tawm av tsawg dua rau kev tsim kho hauv paus, kev puas tsuaj me me rau cov peev txheej av, ntxiv rau kev txo qis ntau ntawm cov pob zeb ua vaj tse, txo cov pob zeb khawb, uas ua rau muaj kev tiv thaiv ib puag ncig ecological; Qhov thib peb, tom qab lub neej ua haujlwm ntawm lub tsev tas sij hawm, cov khib nyiab khov kho uas tsim tawm tom qab lub tsev raug rhuav tshem yog me me, thiab tus nqi rov ua dua ntawm cov khoom siv hlau seem yog siab.

9. Qib siab ntawm kev tsim khoom lag luam

Cov qauv hlau raws li cov hlau H beam kub dov muaj qib siab ntawm kev tsim khoom lag luam, uas yooj yim rau kev tsim tshuab, kev tsim khoom ntau, kev ua haujlwm siab, kev teeb tsa yooj yim, kev lees paub zoo yooj yim, thiab tuaj yeem tsim ua lub tsev tsim khoom tiag tiag, lub Hoobkas tsim choj, lub Hoobkas tsim khoom lag luam, thiab lwm yam. Kev txhim kho cov qauv hlau tau tsim thiab tsav kev txhim kho ntawm ntau pua lub lag luam tshiab.

10. Qhov kev tsim kho ceev ceev

Qhov chaw me me, thiab tsim nyog rau kev tsim kho txhua lub caij nyoog, tsis muaj kev cuam tshuam los ntawm huab cua. Qhov ceev ntawm kev tsim kho ntawm cov qauv hlau ua los ntawm cov hlau kub dov H beam yog li 2-3 npaug ntawm cov qauv pob zeb, tus nqi pauv peev yog ob npaug, tus nqi nyiaj txiag raug txo qis, yog li txuag kev nqis peev. Piv txwv li "Jinmao Tower" hauv Pudong ntawm Shanghai, "lub tsev siab tshaj plaws" hauv Suav teb, lub cev tseem ceeb ntawm cov qauv nrog qhov siab ze li ntawm 400m tau ua tiav hauv tsawg dua ib nrab xyoo, thaum cov qauv hlau-pob zeb xav tau ob xyoos los ua kom tiav lub sijhawm tsim kho.
