Lub zog siab: lub txiaj ntsig lub zog yog siab dua S275JR, haum rau cov qauv muaj zog nrog cov khoom ntim siab dua.
Vuam Perface: Kev Siv Vuam Zoo, Haum rau ntau qhov vuam cov txheej txheem.
Qhov ruaj khov: muaj qhov zoo corrosion tsis kam, haum rau cov dej num sab nraum zoov.
Nta thiab cov txiaj ntsig ntawm HEA220X210x11 H Qhov Beam
Ntu kev ua kom zoo:
Lub head h-nqaj muaj tus nqi sib tw tsim nyog cross-section, dav flanges, thiab kev puas zoo nkauj thiab shear tsis kam.
Lub vev xaib tuab yog qhov nruab nrab, uas yooj yim rau kev txuas thiab teeb tsa.
Tsim qauv tsim:
Ob qhov chaw ntawm flange yog parallel, uas yooj yim rau vuam lossis bolting nrog lwm cov.
Tus ntoo khaub lig-ntu loj tuaj yeem hloov kho raws li cov phiaj xwm kev ua haujlwm, uas haum rau kev tsim kho cov qauv txheej txheem nyuaj.
Kev lag luam efficiency:
Lub HEA220XX2XX11X11 Hlau muaj lub teeb yuag thiab cov nqi thauj khoom qis thiab cov nqi nruab.
Los ntawm cov qauv tsim qauv zoo, cov khoom siv tuaj yeem raug txo kom tsawg thiab tag nrho tus nqi ntawm lub phiaj xwm tuaj yeem txo.
Lub zog siab thiab lub teeb hnyav:
Lub hea220x210x7x11 tsim los ntawm s355jr ua los ntawm qhov hnyav thaum ua kom muaj zog dua qub xws li cov choj nce thiab txuas ntxiv.
