H Beam yog dab tsi?

H-beamyog ib qho kev lag luamH-zoo li tus hlau profile, muaj ib lub vas (lub phaj ntsug nruab nrab) thiab flanges (ob lub phaj transverse). Nws lub npe los ntawm nws zoo ib yam li tsab ntawv "H." Nws yog cov khoom siv hlau ua haujlwm tau zoo thiab pheej yig. Piv rau cov khoom siv ib txwm muajI-beams, nws khav txog qhov modulus loj dua, qhov hnyav sib dua, lub zog siab dua, thiab cov khoom siv kho tshuab zoo dua. Nws yog dav siv hauv kev tsim kho, kev tsim kho choj, thiab kev tsim khoom siv tshuab.

Cov Zoo ntawm H-puab Steel Piv nrog Lwm Cov Hlau

Kev Sib Piv	H-Beam	Lwm Cov Hlau Seem (piv txwv li, I-beam, channel steel, lub kaum sab xis steel)
Kev Tsim Qauv Hla-Seem	H-puab nrog cov flanges sib luag thiab lub vev nyias; kev faib khoom sib xws.	I-beam muaj cov flanges tapered; channel / lub kaum sab xis steel muaj cov seem tsis sib xws, asymmetric.
Lub Peev Xwm Nqa Tau	Lub zog ntev dua 10-20% thiab kev tiv taus khoov sab nraud zoo dua vim yog cov flanges dav dua.	Lub peev xwm thauj khoom tsawg dua; yooj yim rau kev ntxhov siab hauv cov cheeb tsam tshwj xeeb.
Kev Ua Haujlwm Zoo ntawm Qhov Hnyav	Sib dua 8-15% dua li cov seem ib txwm muaj nyob rau hauv tib lub nra hnyav.	Hnyav dua, qhov hnyav ntawm cov qauv tuag thiab lub hauv paus hnyav zuj zus.
Kev Ua Haujlwm Zoo ntawm Kev Tsim Kho	Kev ua haujlwm tsawg kawg nkaus ntawm qhov chaw; kev vuam/bolting ncaj qha txo cov haujlwm los ntawm 30-60%.	Yuav tsum tau txiav/txuas ntau zaus; vuam ntau dua thiab muaj kev pheej hmoo ntawm qhov tsis zoo.
Kev Ruaj Kho thiab Kev Txij Nkawm	Txhim kho kev tiv thaiv xeb/qaug zog; kev txij nkawm txuas ntxiv mus txog 15+ xyoo.	Lub voj voog txij nkawm luv dua (8-10 xyoo); cov nqi kho mus sij hawm ntev dua.
Kev siv tau ntau yam	Muaj nyob rau hauv dov (tus qauv) lossis welded (kev cai) cov duab rau cov choj, cov tsev, thiab lwm yam.	Kev hloov pauv tsawg rau cov haujlwm loj lossis hnyav.

Kev siv cov hlau H-puab hauv lub neej txhua hnub

Cov qauv txhawb nqa rau cov khw loj thiab cov khw muag khoom lojCov qab nthab siab thiab cov thav duab uas muaj peev xwm dais tau qhov hnyav ntawm cov plag tsev ntau txheej hauv cov khw loj feem ntau yog tsim los ntawm kev siv H-beams.

Ru tsev thiab sawv ntsug rau cov chaw ntau pob thiab cov chaw ua yeeb yamPiv txwv li, cov chaw sawv ntawm ib lub tsev nyob, uas tuaj yeem haum rau ntau txhiab tus neeg, thiab lub ru tsev dav dav uas npog tag nrho qhov chaw, vam khom lub peev xwm sib dua thiab lub peev xwm thauj khoom ntawm H-beams.

Cov kev txhawb nqa rau cov khw muag zaub thiab cov khw muag khoom ua liaj ua tebCov hlau scaffolding nyob rau sab saum toj ntawm qee lub khw muag zaub qhib lossis semi-open-air feem ntau siv H-beams ua cov beams tseem ceeb.

Overpasses thiab underpassesCov overpasses uas peb siv txhua hnub feem ntau muaj H-beams ua cov nqaj hlau thauj khoom hauv qab lub lawj choj.

Cov thav duab ntau zaj dab neeg rau cov chaw nres tshebHauv cov chaw nres tsheb ntau txheej hauv cov zej zog nyob lossis cov khw loj, cov pob zeb hauv pem teb thiab cov kem ntawm txhua pem teb yuav tsum txhawb nqa qhov hnyav ntawm cov tsheb, qhov twg lub zog siab thiab kev tiv taus khoov ntawm H-beams tuaj yeem pab tau.

Cov chaw ua si thiab cov chaw hauv cov zej zog nyobNtau lub zej zog nyob muaj cov tsev pheeb suab lossis txoj kev hauv lawv thaj chaw ua si, thiab cov thav duab ntawm cov chaw no feem ntau yog ua los ntawm H-beams (tshwj xeeb tshaj yog cov uas tau kho nrog kev kho mob tiv thaiv xeb).

Cov thav duab ntawm chaw nres tsheb thauj khib nyiabCov chaw nres tsheb thauj khib nyiab hauv nroog xav tau cov qauv ruaj khov los txhawb lub ru tsev thiab cov khoom siv. Cov hlau H-beam qhov kev tiv thaiv xeb (rau qee cov qauv) thiab lub peev xwm thauj khoom yog qhov tsim nyog rau qhov chaw ib puag ncig no, ua kom ntseeg tau tias qhov chaw nres tsheb thauj khib nyiab ua haujlwm ruaj khov.

Cov chaw nres tsheb them nqiCov hlau H-beam feem ntau siv ua lub hauv paus rau cov chaw them fais fab tsheb uas nyob ntawm ntug kev lossis hauv thaj chaw nyob. Nws ua kom lub chaw them ruaj khov thaum tiv thaiv nws ntawm kev sib tsoo tsheb thiab huab cua phem, muab kev thaj yeeb nyab xeeb thaum lub sijhawm them.

Kev loj hlob ntawm cov hlau H-puab

Thaum cov txheej txheem tsim khoom loj hlob tuaj, lub peev xwm tsim khoom ntawm cov khoom tshiabH beamxav tias yuav nce ob npaug hauv rau lub hlis tom ntej, ua rau nws tus nqi ua lag luam sib tw ntau dua. Cov neeg ua lag luam hauv kev lag luam kwv yees tias cov hlau ua tau zoo no yuav dhau los ua qhov kev xaiv tseem ceeb rau cov haujlwm loj hauv tsev hauv peb txog tsib xyoos tom ntej, muab lub hauv paus ruaj khov rau kev txhim kho zoo ntawm kev tsim kho vaj tse hauv kuv lub tebchaws.
