H Beam yog dab tsi?
H-beamsyog cov profiles pheej yig, ua haujlwm tau zoo nrog qhov seem zoo ib yam li tsab ntawv "H." Lawv cov yam ntxwv tseem ceeb suav nrog kev faib thaj tsam seem zoo tshaj plaws, qhov sib piv ntawm lub zog thiab qhov hnyav tsim nyog, thiab cov khoom sib dhos ua ke. Cov khoom no muaj kev tiv thaiv kev khoov ntau txoj kev, yooj yim tsim kho, kev tsim kho sib dua (15% -30% sib dua li cov qauv hlau ib txwm muaj), thiab kev txuag nqi. Piv rau cov qauv I-beams ib txwm muaj (I-beams), H-beams muaj cov flanges dav dua, kev tawv dua sab nraud, thiab kwv yees li 5% -10% txhim kho kev tiv thaiv kev khoov. Lawv cov qauv flange sib luag ua rau kev sib txuas thiab kev teeb tsa yooj yim dua. Lawv siv dav hauv cov ntawv thov hnyav xws li cov tsev loj (xws li cov chaw tsim khoom thiab cov tsev siab), choj, nkoj, thiab lub hauv paus rau kev tsa cov tshuab thiab khoom siv, txhim kho kev ruaj khov ntawm cov qauv thiab txo kev siv khoom.
Cov txiaj ntsig ntawm H-beam
1. Cov Khoom Siv Kho Tshuab Zoo Kawg Nkaus
Muaj Peev Xwm Flexural Muaj Zog: Cov flanges dav thiab tuab (dav dua 1.3 npaug ntawm I-beams) muab lub sijhawm loj ntawm inertia, txhim kho kev ua haujlwm flexural los ntawm 10% -30%, ua rau nws tsim nyog rau cov qauv ntev.
Biaxial Compressive Stability: Cov flanges yog perpendicular rau lub web, ua rau muaj kev sib zog siab thiab kev tiv taus torsional thiab dov zoo dua rauI-beams.
Kev Faib Tawm Kev Nyuaj Siab Sib Xws: Kev hloov pauv ntawm cov ntu sib luag txo qhov kev ntxhov siab thiab ua kom lub neej qaug zog ntev dua.
2. Nyhav thiab Yooj Yim
Qhov Sib Piv Zog Siab Rau Qhov Hnyav: Sib dua 15% -30% dua li cov I-beams ib txwm muaj ntawm tib lub peev xwm thauj khoom, txo qhov hnyav ntawm cov qauv.
Kev Txuag Khoom Siv: Kev siv cov pob zeb ua lub hauv paus txo qis cov nqi tsim kho tag nrho los ntawm 10% -20%.
Cov Nqi Thauj Mus Los Thiab Kev Teeb Tsa Tsawg: Cov khoom siv txheem txo qhov txiav thiab vuam ntawm qhov chaw.
3. Kev Tsim Kho Yooj Yim thiab Ua Tau Zoo
Cov nplaim flange sib luag ua rau muaj kev sib txuas ncaj qha rau lwm cov khoom (cov phaj hlau, cov ntsia hlau), ua rau kev tsim kho ceev dua 20% -40%.
Cov Pob Qij Sib Txuas Yooj Yim: Txo cov pob qij sib txuas nyuaj, ua kom cov qauv ruaj khov, thiab ua kom lub sijhawm tsim kho luv dua.
Cov Qauv Txheem: Cov qauv thoob ntiaj teb lees txais xws li Suav Tebchaws Tus Qauv (GB/T 11263), Nyiv Tus Qauv (JIS), thiab Asmeskas Tus Qauv (ASTM A6) ua kom yooj yim rau kev yuav khoom thiab hloov kho tau.
4. Ntau Yam Kev Siv
Kev Tsim Kho Hnyav: Cov Hoobkas, cov tsev siabcov qauv hlau(xws li lub hauv paus ntawm Shanghai Tower), thiab cov chaw loj (xws li Bird's Nest truss support).
Cov Choj thiab Kev Thauj Mus Los: Cov choj tsheb ciav hlau thiab cov kev hla kev loj (nrog cov kev txhawb nqa lub thawv ntev).
Cov Khoom Siv Lag Luam: Cov tshuab hnyav chassis thiab chaw nres nkoj crane khiav beams.
Kev Tsim Kho Hluav Taws Xob: Cov chaw nres nkoj fais fab thiab cov modules platform roj.
5. Kev Ruaj Ntseg Ib puag ncig
100% Rov Siv Tau Dua: Cov nqi rov ua dua tshiab ntawm cov hlau siab txo cov khib nyiab tsim kho.
Txo Kev Siv Pob Zeb: Txo cov pa roj carbon (txhua tuj hlau hloov nrog pob zeb txuag tau 1.2 tuj CO₂).
Cov ntawv thov ntawm H Beam
Feem ntau siv covHoobkas H Beamsyog rau cov platforms, choj, nkoj thiab chaw nres nkoj. Thaum I Beams feem ntau siv rau cov tsev lag luam lossis lwm yam kev siv sib dua.
Txij li cov chaw siab tshaj plaws mus rau cov chaw tsim kho vaj tse rau pej xeem, los ntawm kev lag luam hnyav mus rau lub zog ntsuab, H-beams tau dhau los ua cov khoom siv tsim kho uas tsis tuaj yeem hloov pauv tau rau kev tsim kho niaj hnub. Thaum xaivTuam Tshoj H beam tuam txhab, cov lus qhia tshwj xeeb yuav tsum tau phim raws li qhov hnyav, qhov ntev, thiab qhov chaw xeb (piv txwv li, cov haujlwm ntug dej hiav txwv xav tau cov hlau weathering Q355NH) kom ua kom lawv muaj kev nyab xeeb thiab muaj txiaj ntsig zoo tshaj plaws.
