Ib lub duav, tseem hu ua H-Shaped Hlau Beam, yog cov qauv hlau txheem steel tiv thaiv nrog kev hla ntawm tsab ntawv "H." Nws muaj ob txoj kab rov tav sib txuas txuas los ntawm ib lub vev xaib ntsug, muab cov khoom muaj peev xwm zoo heev. H Beams tau siv dav siv hauv kev tsim kho thiab kev tsim khoom vim lawv muaj zog thiab kav ntev. Lawv muaj nyob rau ntau qhov ntau thiab tsawg thiab qib kom tau raws li cov cai sib txawv. Piv rau I nqaj, H Beams muaj dav flanges, ua rau lawv ruaj khov nyob rau hauv cov nra hnyav
Dab tsi yog qhov zoo ntawm H-Beam?
Siab zog ua tau zoo:
Tus H-Sau cov khoom siv uas nws xav tau tshaj plaws (flanges rau dabtsi yog khoov, web rau shear), txo qhov hnyav thaum lub zog siab.
Versatility:
Yuav siv tau ua ob qho tib si kab ntsug (txhawb axial loads) thiab kab rov tav cov nqaj hlau (tawm ntawm khoov).
Yooj yim ntawm cov fabrication:
Yooj yim welded, bolted, lossis riveted rau lwm cov tib leeg, ua kom cov teeb tsa ncaj.
Nqi Them Nqi:
Txo cov cuab yeej siv piv rau cov teeb ntxig sib dhos, cov nqi qis dua.
Dab tsi yog qhov tsis zoo ntawm H-Beach?
Tsis muaj zog rau buckling:
Hauv cov kab ntawv siab heev lossis hauv qab cov nra hnyav, cov flanges lossis lub vev xaib yuav sia yog tias tsis raug.
Hluav Taws Kub Siab:
Hlau poob lub zog ntawm kev kub siab, yog li H-Beams hauv cov chaw tua hluav taws-nquag xav tau hluav taws kub.
Corrosion pheej hmoo:
Kev tsis muaj kev tiv thaiv steel h-nqaj hlau yuav xeb muaj xeb lossis xeb ib puag ncig, uas xav tau xim lossis galvanization.
Dab tsi yog qhov zoo ntawm kev siv h cis hauv kev tsim kho?
H Beams muab cov zog zoo dua-rau-hnyav piv, ua rau lawv zoo tshaj rau txoj haujlwm loj-ntsuas. Lawv cov qauv tsim tawm qhov hnyav hnyav, txo qhov kev pheej hmoo ntawm cov qauv kev ua tsis tiav. Lawv kuj yog tus tiv thaiv zoo heev rau khoov thiab sib ntswg, ua kom muaj kev ruaj khov ntev. Tsis tas li ntawd, ha nqaj yog yooj yim rau nruab thiab tuaj yeem yog preabricated, txuag lub sijhawm thiab cov nqi zog. Lawv cov versatility tso cai rau lawv siv rau hauv cov choj, skyscrapers, thiab cov tsev muaj tsev.
Cov ntaub ntawv twg siv los tsim ha nqaj?
H Beams feem ntau yog ua los ntawm cov hlau hlau lossis qib siab-lub zog qis-alloy (hsla) hlau, uas muab kav thiab tiv thaiv kev xeb. Qee qhov tshwj xeeb h Beams yuav siv cov hlau tsis xeb rau ib puag ncig uas yuav tsum tau ua siab dua corrosion. Cov txheej txheem tsim khoom lag luam cuam tshuam nrog kub dov lossis vuam kom ua tiav cov duab uas xav tau thiab muaj zog. Kev tswj kom zoo kom ua kom ntseeg tau tias cov kab teeb tau ntsib cov qauv thoob ntiaj teb zoo li ASTM lossis EN. Kev xaiv zoo yog qhov tseem ceeb heev rau kev ua kom muaj cov nqaj kev ua haujlwm hauv cov ntawv thov tshwj xeeb.
