H Tshooj Hlau Beam Loj Loj
W21x44 h zoo li lub nqaj: "W21" txhais tau tias qhov siab ntawm cov hlau yog li 21 nti, thiab "44 phaus, txog 65.5kg / m.
W21x48 h hom nqaj: Qhov siab tseem yog 21 nti (533.4mm), thiab qhov hnyav ib txhais ko taw yog 48 phaus, txog 71.5kg / m.
H HOM Hlau Beam Khoom Siv Khoom Siv
Ob hom hlau feem ntau tuaj yeem ua los ntawm cov ntaub ntawv xws li A36 lossis A57GR50.
A36 Khoom Siv: C Tsawg dua lossis sib npaug ntawm 0}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Cu ntau dua los yog sib npaug rau 0.20 (thaum tooj liab-muaj hlau yog teev); yield strength Greater than or equal to 250MPa, tensile strength 400 - 550MPa, elongation Greater than or equal to 20%; Muaj cov cuab yeej siv cov khoom siv kho zoo, vuam cov khoom thiab kev ua cov khoom.
A572Gr5 {{0 Cov Khoom Siv: C Tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug lossis nce ntxiv lossis sib npaug 0.05, NB 0. {005 - 0. 05; yield strength Greater than or equal to 345MPa, tensile strength 490 - 600MPa, elongation 22 - 35%, Charpy impact energy at 0 degree Greater than or equal to 45J; Muaj lub zog siab, siab tawv, zoo nkees ua hauj lwm thiab corrosion tsis kam.
Kev ua tau zoo ntawm cov khoom H Be Be
Siab zog: Ob leeg A36 thiab A572GR50 muaj lub zog siab thiab tuaj yeem tiv thaiv loj loj.
Zoo BRADE YIG: Tus H-puab cov kev tsim qauv hla kev ua tau zoo hauv kev tawm tsam cov tub rog thiab yog haum rau cov teeb meem uas tsoo lub neej.
Zoo heev Vuam Kev Kawm: Ob cov ntaub ntawv tau yooj yim rau Weld, thiab kev ncaj ncees thiab cov neeg kho mob ntawm cov qauv tuaj yeem lav tom qab vuam.
Kev ua haujlwm zoo: Nws yooj yim rau kev txiav, khoov, xuas nrig ntaus, xuas nrig ntaus thiab lwm yam kev ua haujlwm, thiab tuaj yeem ua tau raws li cov kev tsim qauv.
Cov chaw thov ntawm cov hlau nqaj h
Lub Tsev Cov Qauv: Nws tuaj yeem siv rau cov vaj tse kab teeb thiab cov kab ke siab, ua rau tus kheej hnyav, thiab cov khoom siv seismic thiab cov seismic thauj khoom.
Choj Engineering: Nws yog cov khoom tseem ceeb rau cov choj kev ua choj. Nws tuaj yeem siv rau hauv cov teeb tseem ceeb, cov piers thiab lwm feem ntawm cov choj los ris cov tsheb thauj khoom ntawm cov tsheb thiab cov neeg taug kev.
Kev tsim tshuab: Qee cov khoom siv hluav taws xob loj cov khoom siv nkhaus, cov hauv paus uas muaj peev xwm siv hom hlau no los muab kev txhawb nqa ruaj khov rau cov khoom siv.
