Yog, h {- Beams tau siv nyob rau hauv cov chaw nyob rau pem teb jaw, thiab thauj} bearing phab ntsa. Pem teb joists (me h - Beams zoo li H150 × 75) luv ntawm phab ntsa, txhawb nqa hardwood lossis cov kav hlau tsis muaj sia. Tig lub ru tsev ci (piv txwv li, H200 × 100) Hloov lub zog zoo dua thiab hluav taws kub tsis zoo rau cov ru tsev loj (piv txwv li cov tsev niaj hnub nrog cov lofts niaj hnub nrog qhib lofts). Thauj khoom -} Cov muag khoom phab ntsa siv h- nqaj ua headers (qhov rai tshaj lub phab ntsa lub cev hnyav. H - Beams hauv cov tsev feem ntau pleev xim lossis npog nrog lub tshuab ziab khaub ncaws kom zoo rau kev ua kom loog. Lawv kuj yog lub teeb ci, ua kom muaj kev txhim kho yooj yim dua li cov hlau tawv, thiab lawv cov qauv ua kom ua kom tau cov qauv hauv tsev kav ntev txog xyoo.
Yuav ua li cas yog h - Beams siv hauv nkoj?
Hauv lub nkoj nkoj, h {- kab teeb tau siv rau lub hull tus ncej (cov hlua khi thiab cov thav ntawv txhawb nqa. Cov hlua khi (Longitudinal h- Beams) khiav raws lub nkoj ntev, muab cov teeb meem rigidity thiab txhawb nqa Hull ob sab. Thav ntawv (transverse h {4 4}} kab teeb) txuas cov hlua khi, tsim lub hull lub ntsej muag thiab tiv thaiv dej siab. Lawj txhawb nqa (me h - kab teeb) tuav lub lawj nyob rau hauv qhov chaw, txhawb nqa khoom lossis thauj khoom. H - Beams yog haum rau cov nkoj vim tias lawv muaj zog tsis tau (rov txo cov roj av thaum- ·36). Piv txwv li, cov nkoj thauj khoom siv h - Cov hlua khau ci los txhawb nqa cov pob hull hnyav, ua kom lub hull ua kom ruaj khov nyob rau ntawm hiav txwv.
Lub teb chaws twg yog cov neeg tsim khoom loj tshaj plaws ntawm h - Beams?
Qhov loj tshaj plaws h - Beam cov neeg tsim khoom lag luam yog Tuam Tshoj, Nyiv, Tebchaws Asmeskas, Is Nrias teb Kauslim. Tuam Tshoj ua thoob ntiaj teb, nrog cov neeg tsim khoom loj xws li baosteel thiab Angang Steel, Accounting rau ~ 50% ntawm thoob ntiaj teb kev tsim khoom. Nyiv cov hlau nippon thiab jfe steel yog paub rau high- zoo h} ci ntsa iab (siv rau hauv cov choj thiab skyscrapers). Teb Chaws Asmeskas muaj cov chaw tsim khoom nucor thiab arcelormittal USA, muab h - kab rau kev tsim kho hauv tsev. Is Nrias teb Jsw Steel thiab Sab Qab Teb Kauslim tseem pab tau ntau, nrog Posco tsom mus rau qhov siab h} duab rau cov phiaj xwm kev muaj chaw. Cov teb chaws cov lag luam loj loj, cov chaw tsim khoom lag luam loj, thiab cov kev xav tau siab rau cov khoom siv, tsav tsheb h} nqaj ntau lawm.
Lub teb chaws twg import feem ntau h - Beams?
Lub teb chaws importing feem ntau h - Beachs suav nrog Tebchaws Asmeskas, Tebchaws Asmeskas, Australia, Nyab Laj, Indonesia). US imports h - Beams los ntawm Tuam Tshoj, Mexico, thiab Canada kom tau raws li kev tsim kho siab (piv txwv li, infrastructure tej yaam num). Lub teb chaws Yelemees yuav los ntawm Tebchaws Poland, Fabkis, thiab Tuam Tshoj rau nws cov kev lag luam thiab cov haujlwm. Saudi Arabia thiab Australia Ntshuam h {Beams rau loj {12}, roj av roj ntau ntxiv. Cov teb chaws Ashast Asian ntshuam los ntawm Tuam Tshoj thiab Nyij Pooj los txhawb kev ceev xwm txheej nrawm (piv txwv li, lub tsev skyscrapers, txoj kev loj). Ntshuam tagnrho nyob ntawm cov hlau hauv zos tsim, tsim kev thov kev tsim kho, kho ntshiv, ntshuam (import} Beams yuav pheej yig dua li cov khoom lag luam hauv tsev).
Yog vim li cas h - Beams Nrov nrov hauv Suav teb cov kev tsim kho?
H - ci ci yog nrov nyob rau hauv Suav teb vim muaj kev siv zog ua haujlwm (skyscrapers, kev loj, muaj peev xwm ntau lawm. Tuam Tshoj qhov hlau loj Mills (Baosteel, Angang) tsim muaj h- Beams ntawm cov nqi qis, ua rau lawv pheej yig rau cov phiaj xwm. Lawv lub zog - - qhov hnyav rau cov tsev siab uas muaj zog nrog qhov chaw muaj tsawg, txuag thaj av. Ib qho ntxiv, Tuam Tshoj lub tsev lis dej num (GB / T 11263) ua kom haum h {10} Be} Beam Qhov ntau thiab tsawg, ua kom muaj kev sib dhos yooj yim Piv txwv li, lub Shanghai ntauwd (632M) siv ntau txhiab h- kab teeb rau nws tus ncej, raws li lawv tuaj yeem txhawb nqa pej thuam hnyav thiab tiv thaiv cua lo. H - Beams kuj haum nrog Tuam Txhab Infrastructure Cov Phiaj Xwm Txheej Txheem (piv txwv li txoj siv thiab kev tsav tsheb siv ntau.
