W14x311 W14x342 W14x455 Wide flange H-beam
Cov khoom siv dav dav rau W14x311 W14x342 h hom steel beam yog A36, A572GR50, A992, thiab lwm yam. Siv A992 cov khoom ua piv txwv, nws cov tshuaj muaj pes tsawg leeg suav nrog cov ntsiab lus carbon ntawm 0.27% - 0.35%, silicon cov ntsiab lus ntawm 0.93% - 1.20%, 0.8% manganese cov ntsiab lus thiab manganese sulfur ntsiab lus tsis ntau tshaj 0.025%, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm mechanical zog, lub tensile lub zog yog tsis tsawg tshaj li 560MPa, lub yield zog tsis tsawg tshaj li 460MPa, lub elongation tsis tsawg tshaj li 10%, tus ntoo khaub lig-sectional shrinkage yog tsis tsawg tshaj li 45%, thiab lub zog 39J.
Nta ntawm W14x311 W14x342 h hom kab teeb
Cov ntoo khaub lig zoo heev -sectional kev ua tau zoo: Tus ntoo khaub lig-sectional duab ntawm H- zoo li cov hlau yog kev lag luam thiab tsim nyog, thiab cov khoom siv kho tshuab zoo. Piv nrog rau qhov zoo tib yam I-beam, nws muaj qhov zoo ntawm tus ntoo khaub lig loj-sectional modulus, lub teeb yuag, thiab hlau txuag, uas tuaj yeem txo cov qauv hauv tsev los ntawm 30%-40%.
Kev tsim kho yooj yim: Vim tias sab hauv thiab sab nraud ntawm ob txhais ceg yog tib yam thiab cov ceg xaus yog cov kaum sab xis, thaum sib dhos thiab sib xyaw ua ke, cov khoom siv vuam thiab riveting tuaj yeem txuag tau 25%.
Cov khoom siv ntawm W14x455 h steel profile nyob ntawm qib steel siv, thiab cov khoom siv muaj xws li ASTM A36 cov qauv steel beam, A992 steel beam lossis A572, thiab lwm yam. W14x455 h seem steel feem ntau yog tsim los ntawm cov txheej txheem kub dov, qhov twg steel billet yog dov ntawm qhov kub thiab txias kom ntseeg tau tias cov khoom sib xws thiab cov khoom zoo. Piv nrog cov welded H- zoo li cov hlau, cov hlau kub dov tau qis dua qhov kev ntxhov siab thiab kev ruaj ntseg zoo dua.
Qhov zoo ntawm W14x455 steel h profile
Siab load-bearing peev: tsim nyog tus ntoo khaub lig-sectional tsim thiab zoo heev zog-rau- luj piv.
Kev tsim kho kev ua haujlwm: yooj yim rau tshuab, txuas thiab nruab, haum rau txhua yam - huab cua tsim.
Structure stability: muaj zog tiv thaiv kev co thiab kev cuam tshuam, haum rau huab cua puag ncig.
Qhov chaw txuag: piv nrog cov pob zeb ua vaj tse, tus ntoo khaub lig me me -ib ntu tuaj yeem ua rau thaj chaw siv tau zoo.
