EN1337-1: 2000 Daim Ntawv Qhia:Qauv BearingsTxuj
EN1337-1: 2000 yog lub hauv paus ntawm European Standard (EN) rauqauv bearings, tsim los ntawm European Committee for Standardization (CEN) kom muaj kev nyab xeeb, sib xws, thiab kev ntseeg siab thoob plaws hauv cov phiaj xwm hauv CEN cov tswv cuab. nws ua haujlwm raws li phau ntawv tsim qauv dav dav rau cov kabmob siv hauv cov txuas hniav thiab lwm cov qauv kev tsim vaj tsev hauv vaj tse - ua rau nws tseem ceeb rau cov kws tsim khoom, cov chaw tsim khoom, thiab cov neeg cog lus taug kev European kev tsim kho.
Cov ntsiab lus tseem ceeb ntawm EN1337-1: 2000
Kev pom zoo los ntawm CEN thaum Lub Plaub Hlis 2000, EN1337-1 yog lub hauv paus ntawm EN1337 series, uas muaj 11 ntu uas suav nrog txhua yam ntawmqauv bearings. Thaum Ntu 1 qhia txog kev tsim qauv thoob ntiaj teb, lwm qhov chaw dhia mus rau hauv hom tshwj xeeb: zawv zawg ntsiab (Pib 2),elastomer bearings(Part 3),lauj kaub bearings(Part 5),kheej kheej bearing(Part 7) thiab ntau ntxiv. Qhov tseem ceeb, Tshooj 1 thiab Ntu 2 yuav siv tau ib txhij, nrog rau lwm qhov chaw tom qab sib cais- ua kom muaj kev sib koom ua ke rau kev tsim, kev teeb tsa, thiab kev saib xyuas.
Tus qauv muaj nyob rau hauv peb hom lus (Lus Askiv, Fab Kis, German) thiab yuav tsum tau ua rau CEN cov tswvcuab hauv lub xeev, hloov cov qauv kev tsis sib haum xeeb hauv tebchaws thaum Lub Kaum Ob Hlis 2000. Kev ua raws cai yuav tsum tau ua raws li CE kos npe raws li Txoj Cai Siv Khoom Siv (CPR), qhov tseem ceeb rau kev lag luam bearings hauv European lag luam.
Dab tsi EN1337-1 Npog (thiab Nws Tsis Yog)
EN1337-1 siv rauqauv bearings-cov khoom uas xa cov khoom thauj, tso cai rau kev sib hloov thiab kev txhais lus, thiab txhim kho cov qauv. Nws suav nrogtsau bearings, coj bearings, thiabdawb bearingsrau ob qho tib si txuas hniav thiab tsis yog - choj cov qauv, nrog cov kev faib tawm kom meej thiab cov cim rau ntau hom (xws li, elastomeric, kheej kheej, cov menyuam bearings).
Qhov tseem ceeb, tus qauv tsis suav nrog cov xwm txheej tshwj xeeb: cov kabmob feem ntau tsim los xa cov sijhawm, txhawb nqa-cov kabmob tiv taus, txav tauchoj bearings, pob zeb pob zeb, thiabcov khoom siv seismic. Cov kabmob ib ntus (siv thaum lub sijhawm tsim kho) tsis raug tswj tab sis tuaj yeem raug xa mus raws li kev qhia. Nws kuj tsis suav nrog tag nrho cov qauv tsim lossis kev xav txog geotechnical, uas yuav tsum tau ntxiv Eurocodes (xws li ENV 1991-1, ENV 1992-2).
Core Design Requirements
EN1337-1 tseem ceeb rau kev ua tau zoo thiab kev ua haujlwm ntev nrog cov ntsiab lus tseem ceeb:
Kev ruaj ntseg:Bearings yuav tsum tau kuaj xyuas, tswj tau, thiab hloov tau los khaws cov haujlwm ua haujlwm thoob plaws hauv lub neej.
Tswj Movement:Cov qauv tsim yuav tsum tso cai rau kev sib hloov thiab kev txhais lus thaum txo qis reactive rog, nrog tsawg presetting (ua ntawm lub Hoobkas yog tias tsim nyog).
Kev kuaj xyuas kev nyab xeeb:Kev zawv zawg tiv thaiv tau raug txheeb xyuas siv kev lag luam- pom qhov muaj nuj nqis ntawm kev sib txhuam thiab kev nyab xeeb, nrog kev saib xyuas tshwj xeeb rau cov qauv kev thauj khoom dynamically (xws li, railway choj) qhov kev sib txhuam ib leeg tsis tuaj yeem tiv taus cov kab rov tav.
Clearance & Marking: Tag nrho cov kabmob tshem tawm tsuas yog txwv rau 2 hli kom tsis txhob muaj kev cuam tshuam ntawm cov qauv, thiab tag nrho cov kabmob yuav tsum tau sau nrog cov chaw tsim khoom, lub peev xwm thauj khoom, kev txwv tsis pub txav mus los, thiab cov lus qhia kev teeb tsa.
Installation & Thauj: Ntau -cov khoom siv bearings yuav tsum tau clamping ib ntus rau kev thauj mus los nyab xeeb, thiab cov khoom hnyav yuav tsum suav nrog kev nqa nqa. Kev teeb tsa kev teeb tsa tau pom zoo hauv kev sau ntawv ntawm cov neeg yuav khoom thiab cov chaw tsim khoom.
EN1337 Series vs EN15129
Thaum EN1337 tsom rau kev dav davqauv bearings, EN15129 yog tus qauv tshwj xeeb rauCov khoom siv tiv thaiv seismic(piv txwv li, dampers, cais tawm) hauv cov choj thiab cov vaj tse. Qhov sib txawv tseem ceeb yog nyob rau hauv lawv lub hom phiaj tseem ceeb: EN1337 ua kom ntseeg tau tias kev thauj khoom thauj thiab tswj kev txav mus los raws li cov txheej txheem, thaum EN15129 hais txog kev nqus hluav taws xob thiab kev hloov pauv thaum muaj av qeeg.
Cov phiaj xwm hauv cheeb tsam seismic feem ntau ua khub EN1337 (rau txhua hnub kev coj tus kheej tsim) nrog EN15129 (rau seismic resilience), raws li EN1337 qhia meej tsis suav nrogcov khoom siv seismic. Qhov kev sib txuas ua ke no ua kom cov qauv ua tau raws li ob qho tib si niaj hnub thiab cov kev xav tau hnyav heev.
Vim li cas EN1337-1 Teeb meem
Rau cov tuam txhab, EN1337-1 kev ua raws cai tsis yog- sib tham tau rau kev nkag mus rau European lag luam. Rau cov kws tshaj lij, nws muab cov txheej txheem sib koom ua ke los tsim cov kabmob uas sib xyaw ua ke nrog cov qauv, txo ntawm - qhov yuam kev ntawm qhov chaw. Cov neeg cog lus tau txais txiaj ntsig los ntawm kev txhim kho thiab kev saib xyuas kom meej, ua kom muaj kev ua haujlwm ntev.
TS EN 1337-1: 2000 tseem yog cov cuab yeej tseem ceeb rau kev tsim kho nyob sab Europe, tsim qauv qauv coj los txhawb kev nyab xeeb thiab kev sib raug zoo. Nws exclusion ntawmcov khoom siv seismicqhia txog qhov xav tau ntawm EN15129 hauv siab - thaj chaw muaj kev pheej hmoo, tab sis nws cov ntsiab lus tseem ceeb ntawm kev tswj xyuas, tswj kev txav mus los, thiab kev nyab xeeb tseem yog lub hauv paus rau kev ntseeg tau.qauv bearings.
Txawm hais tias koj tab tom tsim tus choj, cov khoom siv bearings, lossis tshawb xyuas qhov ua tau raws li qhov project, EN1337-1 muab cov lus qhia thoob ntiaj teb xav tau rau kev ua raws cai, cov txheej txheem ruaj khov.
