European Standard HEA 400 steel H beams, muaj nyob rau hauv ib tug ntau yam ntawm cov qhab nia xws li S235 Jr, S275 Jr, S355 Jr, S355j2, thiab S355nl, yog precision-engineered structural Cheebtsam raws li EN 10025 cov qauv kev lag luam, uas ua rau lawv xav tau kev lag luam thoob ntiaj teb. rau European zoo benchmarks. Raws li ib tug tswv cuab ntawm HEA (European Wide Flange Beams) series, HEA 400 profile tshwj xeeb yog tsim los rau kev ua haujlwm zoo tshaj plaws - bearing efficiency, combining a balanced cross{12}}sectional geometry with high- steel grades to deliver exceptional structural performance.
Ua ntej thiab qhov tseem ceeb tshaj plaws, kev ua raws li EN 10025 (tus qauv European rau kub- dov cov qauv steel) ua kom zoo ib yam, cov khoom siv kho tshuab zoo ib yam, thiab nruj qhov tseeb ntawm txhua HEA 400 kab teeb. Cov kev xaiv qib sib txawv ua tau raws li qhov yuav tsum tau ua ntawm cov phiaj xwm sib txawv: S235 Jr, dav dav - lub hom phiaj cov qauv hlau, muaj qhov tsawg kawg nkaus lub zog ntawm 235 MPa thiab tensile zog ntawm 360-510 MPa, haum rau cov ntawv thov kev ntxhov siab tsawg rau nruab nrab; S275 Jr elevates kev ua tau zoo nrog qhov tsawg kawg nkaus yield zog ntawm 275 MPa thiab tensile zog ntawm 370-530 MPa, zoo tagnrho rau cov qauv uas yuav tsum tau txhim kho load{23}}cov kabmob muaj peev xwm; S355 Jr, qib siv dav, muab qhov tsawg kawg nkaus lub zog ntawm 355 MPa thiab tensile lub zog ntawm 470-630 MPa, ntsuas ductility thiab rigidity rau ntau yam qauv siv. Rau cov kev xav tau ntau dua, S355j2 muaj kev txhim kho kev tiv thaiv (kuaj ntawm -20 ° C) thaum tuav lub 355 MPa yam tsawg kawg nkaus tawm lub zog, thiab S355nl ntxiv txhim kho qhov kub thiab txias (kuaj ntawm -50 ° C) nrog rau kev ua haujlwm zoo, ua rau nws tsim nyog rau qhov chaw txias thiab cov qauv tseem ceeb ntawm cov kabmob.
Lub HEA 400 profile tus qauv tsim yog lub cim ntawm nws qhov kev ua tau zoo. Cov yam ntxwv los ntawm qhov dav, qhov sib npaug ntawm cov flanges thiab lub vev xaib tuab, H-zoo li tus ntoo khaub lig- ntu kom ntseeg tau tias cov khoom thauj tsis sib xws, txo qis kev ntxhov siab thiab ua kom muaj zog tiv thaiv kev khoov, shear, thiab torsional quab yuam. Tus txheej txheem qhov ntev ntawm HEA 400 (nrog rau qhov siab ntawm 400 mm) pab txhawb kev sib txuas ua ke rau hauv ua ntej - engineering structural systems, simplifying fabrication, tsheb thauj mus los, thiab ntawm - chaw sib dhos. Qhov kev tsim kom zoo dua no tsis tsuas yog txhim kho cov qauv kev ua tau zoo xwb tab sis kuj txo cov khoom pov tseg thiab tag nrho cov nqi ntawm qhov project, ua raws li kev tsim kho niaj hnub.
Cov European Standard HEA 400 H beams muaj ntau yam nyob rau hauv ib tug dav spectrum ntawm structural engineering daim ntaub ntawv. Los ntawm cov tuam tsev lag luam thiab kev lag luam (xws li siab - nce lub moj khaum, warehouses, thiab Hoobkas los ntawm) mus rau qhov tseem ceeb infrastructure tej yaam num (xws li cov choj, railways, txoj kev loj, thiab chaw nres nkoj chaw), lawv robust kev ua tau zoo thiab qib saj zawg zog ua rau lawv hloov mus rau ntau yam load thiab ib puag ncig tej yam kev mob. Lub hauv paus weldability thiab machinability ntawm S235 rau S355 qib steels ntxiv nthuav lawv cov kev siv tau, tso cai rau kev cai fabrications thiab kev hloov kho kom tau raws li qhov project xav tau. Thaum ua ke nrog kev kho kom haum rau saum npoo (xws li, galvanization, epoxy txheej), lawv kuj tuaj yeem ua kom muaj kev tiv thaiv corrosion, ncua kev pab cuam lub neej nyob rau hauv ib puag ncig hnyav xws li cov ntug dej hiav txwv lossis thaj chaw muaj kev lag luam.
Txhua HEA 400 H beam ua tiav cov txheej txheem tswj kom zoo thoob plaws hauv cov txheej txheem tsim khoom, los ntawm cov khoom siv raw mus rau qhov kawg tshuaj ntsuam xyuas. Ua raws li EN 10025 cov qauv, lawv raug rau qhov tsis yog - kuaj kev puas tsuaj (nrog rau kev kuaj ultrasonic), kev tshuaj xyuas qhov ntev, thiab kev ntsuas cov cuab yeej cuab tam kom ua tau raws qib - cov kev cai tshwj xeeb. Qhov kev cog lus tsis txaus ntseeg no tau lees paub tias cov kab hluav taws xob xa khoom txhim khu kev qha, nyab xeeb, thiab ntev - kev ua tau zoo, ua rau lawv yog ib qho tseem ceeb ntawm cov engineers thiab cov neeg cog lus nrhiav kom tau raws li European cov qauv kev nyab xeeb thiab kev nyab xeeb.
