Material Standards & Choj Engineering Suitability:
Txhua qib uas tau teev tseg raug xaiv rau nws qhov kev ua tau zoo hauv cov qauv txheej txheem:
ASTM A992 Qib Siab Zoo rau Framing:Qhov no yog qhovpredominant khoom specification rau dav -flange duab nyob rau hauv niaj hnub steel siv. Nws muaj lub zog tsawg dua qhov muaj zog (50 ksi / 345 MPa) dua li A36, nrog rau kev tswj nruj ntawm cov tshuaj muaj pes tsawg leeg los xyuas kom meej weldability zoo dua, txhim kho ductility, thiab muaj zog zoo ib yam - rau - tawm los piv. Nws yog tuscov khoom ntawm kev xaiv rau seismic zones thiab tseem ceeb choj cov tswv cuab.
ASTM A36 (Lub hom phiaj dav dav):Cov pa roj carbon ntau yam nrog 36 ksi (250 MPa) qhov tsawg kawg nkaus tawm los, haum rau ntau yam khoom siv uas cov khoom txhim kho ntawm A992 tsis yog tshwj xeeb.
EN S275 & GB Q235B:European thiab Suav sib npaug, feem, muab cov txiaj ntsig zoo ntawm kwv yees li 275 MPa thiab 235 MPa. Lawv muab kev txhim khu kev qha rau kev siv cov qauv siv dav dav thiab feem ntau tau teev tseg hauv cov haujlwm hauv cheeb tsam.
GB Q345B (High-Lub zog qis-Alloy):Nrog rau 345 MPa yield zog, nws yog piv rau ASTM A992 hauv kev ua haujlwm zoo thiab siv dav hauv kev xav tau Suav cov phiaj xwm kev tsim kho rau nws cov khoom zoo heev - cov kabmob muaj peev xwm.
JIS G3101 SS400:Ib qib Japanese tus qauv txhais los ntawm nws qhov tsawg kawg nkaus tensile lub zog (400 MPa), feem ntau siv hauv kev tsim kho thiab kev lag luam thoob plaws Asia.
Cov txheej txheem tsim khoom: Kub-Rolled vs. Welded:
Kub-Rolled H-Beams:Ua los ntawm kev dhau lub rhuab steel billet los ntawm ib tug series ntawm txoj kev mills. Qhov no yog qhov feem ntau thiab tus nqi -txoj kev ua tau zoo rau kev tsim cov qauv dav - flange seem. Nws tsim cov qauv zoo ib yam, muab cov tawv tawv zoo heev thiab yog qhov zoo tagnrho rau feem ntau ntawm cov kab thiab kab ntawv hauv cov choj piers, girders, thiab kev txhawb nqa.
Welded (Ua-Up) H-Beams:Fabricated los ntawm welding ua ke peb cais steel phaj (ob flanges thiab ib lub web). Cov txheej txheem no tso cai rauheev customizationnyob rau hauv qhov ntev (qhov tob, dav, tuab) thiab kev siv cov qib steel sib txawv rau lub vev xaib thiab flanges los txhim kho cov khoom siv tau zoo. Welded kab teeb yog qhov tseem ceeb rauntev -span choj girders, hnyav loaded beams hloov lwm lub tsev, los yog tej daim ntawv thov uas yuav tsum tau tsis yog - tus qauv loj tshaj qhov scope ntawm kub- dov profiles.
Daim ntawv thov kom pom tseeb: Choj Tsev:
Hauv kev tsim choj, Wide Flange H-Beams yog lub hauv paus pob txha pob txha rau ntau hom choj, nrog rau cov choj girder, viaducts, thiab kev txhawb nqa choj. Lawv cov qauv tsim muaj xws li:
Optimal Section Modulus:Qhov dav flanges tso cov khoom siv ntau dua ntawm qhov kawg, ua kom muaj zog tiv thaiv lub sijhawm khoov los ntawm cov tsheb thauj khoom thiab qhov hnyav tuag.
Zoo Torsional Stability:Lub H-puab muab rigidity ntau dua piv rau I- kab teeb, uas yog ib qho tseem ceeb rau lateral stability thaum lub sij hawm tsim thiab nyob rau hauv asymmetric loads.
Fabrication Efficiency:Lawv cov khaub ncaws, tiaj tiaj ua kom yooj yim rau kev sib txuas lus nthuav dav, txawm tias siv siab - lub zog bolting lossis vuam, kom ua tau zoo ntawm - qhov chaw sib dhos.
