H-section steel yog ib qho kev lag luam thiab kev ua haujlwm siab profile nrog kev ua kom zoo dua qhov kev faib tawm ntawm cheeb tsam thiab qhov tsim nyog lub zog-rau-qhov hnyav. Nws yog lub npe vim nws seem yog tib yam li tsab ntawv Askiv "H". Txij li txhua qhov chaw ntawm H-shaped steel yog teem rau ntawm txoj cai kaum, H-zoo li tus hlau muaj qhov zoo ntawm qhov muaj zog dabtsi yog khoov nyob rau hauv tag nrho cov lus qhia, kev tsim kho yooj yim, txuag nqi, thiab lub cev nyhav. Nws yog dav siv hauv kev lag luam, kev tsim kho, txuas hniav, thiab roj drilling platforms. Hais txog lwm yam, hnub no GNEE yuav qhia koj txog nws qhov tseem ceeb siv.
Beam thiab kem Cheebtsam nyob rau hauv industrial thiab civil tsev steel lug; steel qauv load-bearing brackets rau industrial lug; steel pawg thiab txhawb cov qauv rau pej xeem tej yaam num; cov khoom siv hauv tsev xws li petrochemical thiab hluav taws xob fais fab; long-span steel choj Cheebtsam; shipbuilding thiab machinery manufacturing Ncej qauv; tsheb ciav hlau, tsheb, tsheb laij teb girder bracket; chaw nres nkoj conveyor siv, txoj kev loj baffle bracket.
Tus ntoo khaub lig-sectional duab ntawm H-zoo li tus hlau yog zoo heev raws li txoj cai ntawm mechanics, nrog rau nruab nrab nyob rau hauv ntom thiab sib npaug kev ntxhov siab. Piv nrog rau cov I-beams zoo tib yam, txawm hais tias nws qhov hnyav yog lub teeb, nws cov qauv ruaj khov dua, tso cai rau lub tsev kom ua tiav av qeeg thaum txuag nqi.
H-shaped steel tau pib hloov qhov zoo tib yam inclined-leg I-beams hauv cov teb chaws tsim. Nws tuaj yeem txuag tau 30% ntawm cov hlau thaum siv hauv kev tsim kho kev lag luam, thiab kwv yees li 20% thaum siv cov txuas hniav, tshuab thiab lwm yam lag luam. Nws yog ib qho kev lag luam steel hlau thiab yog ib qho tseem ceeb hauv ntiaj teb steel ntau lawm. txoj kev loj hlob.
Kev siv H-shaped steel hauv kev lag luam thiab pej xeem cov tsev tsis tsuas yog txuag kev ua haujlwm thiab txo cov nqi ntau dua li siv I-shaped steel, tab sis kuj txo cov hlau siv. Piv txwv li, yog tias lub Hoobkas steel qauv txais cov kub dov I-beam steel thiab kub dov dav-flange H-beam steel, cov hlau noj yuav raug txo los ntawm 15% -20%.
