Lub ru tsev hnub ci vaj huam sib luag mounting bracket yog ua los ntawm kub-dip galvanized carbon steel bracket, thiab cov los ua ke yog mounted ntawm aluminium alloy txoj hlua los ntawm txoj kev rov qab phaj los yog ib tug clamp. Lub fasteners yog ua los ntawm cov hlau tsis muaj steel. Lub bracket yog tsim los ntawm cua cua tsis kam ntawm 30 m / s, txav rau sab nraum zoov sab nraum zoov.
Ua ntej, cov ntaub ntawv thiab kev ua haujlwm yuav tsum muaj:
1. Khoom yuav tsum: Cov khoom tseem ceeb ntawm cov hlau xaiv hnub ci uas yog cov Qub D235B, thiab lub vuam qws yog E43 series electrode.
2, cov khoom yuav tsum tau ua: cov qauv steel hlau ntawm cov khoom siv loj ntawm lub ntsiab, lub qhov ntev, qhov kis ntawm qhov sib tw, txias tw tua thiab lwm yam khoom siv yuav tsum ua raws li "carbon carbon steel" (GB / T700-2007).
3. Yuav tsum muaj cov tshuaj lom neeg muaj pes tsawg: Cov ntsiab lus ntawm cov roj carbon, phluxor, phosphorus thiab lwm yam tshuaj cov ntsiab ntawm cov qauv steel hlau uas tsim cov khoom tseem ceeb yuav tsum ua raws li cov cai "Carbon Structural Steel" (GB / T700-2007).
Qhov thib ob, kev xeb tshem tawm txoj kab thiab kev tshem tawm cov xeb:
1. Lub tshuab hluav taws xob ua hluav taws xob yuav tsum tau kho qhov quav. Tus cwj pwm thiab qhov qhoos siab yuav tsum ua raws li cov kev cai ntawm lub teb chaws tam sim no "Corrosion qib thiab kev xyaw qib ntawm cov hlau ua ntej pleev xim" (GB8923-88).
2. Txwv txoj kev: lub tshuab ua rau lub cav yuav tawg tau los ntawm blasting los yog tua peening. Yog siv tshuaj xeb tawm, cov tshuaj tua kab mob nrog ob lossis ntau dua kev ua haujlwm ntawm xeb tawm, phosphating thiab passivation yuav tsum siv. Nws ua raws li lub tebchaws tam sim no "Cov Kev Siv Cov Kev Siv Zis rau Cov Khoom Siv Ua Ntej Cov Khoom Siv Ua Ntej Cov Khoom Siv" (GB / T 12612-2005).
3. Kev txo theem: Kev xyuam xim yuav tsum ua raws li Sa2 1/2 qhov yuav tsum tau muaj.
Thib peb, kev tiv thaiv kev ruaj ntseg:
1. Cov hlau tiv thaiv txais txoj kev los tiv thaiv corrosion ntawm cov hlau tiv thaiv txheej txheem. Cov hlau hnub ci qauv ua qauv yog tag nrho kub-dip galvanized txheej, thiab kub-dip galvanizing yuav tsum tau raws li cov tseev kom muaj ntawm cov kev cai thiab kev sim rau kub-dip galvanizing ntawm hlau-clad steel qhov chaw (GB / T13912-2002) , galvanized txheej Lub thickness tsis tsawg dua li 80 m.
2, galvanizing thickness detection: thickness ntawm lub galvanized txheej yog kuaj raws li tus "Technical Requirements thiab kev sim rau cov kub Dip Galvanizing Txheej ntawm Cov Ntawv Hlau Npog".
3. Kub-dip galvanizing los tiv thaiv rhuav tshem cov ntaub ntawv: Siv cov khoom tsim tawm los tsim kev lag luam tawm tom qab kub dip galvanizing.
Qeb plaub, aluminium alloy khoom
1, cov khoom siv: cov khoom siv feem ntau xaiv 6061 lossis 6063.
2. Kev ua tiav cov kev ua haujlwm: Qhov zoo, tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv cuab yeej ntawm cov khoom txhuas uas tau xaiv yuav tsum ua raws li cov kev cai ntawm GB5237.1.
3, qhov kev kho mob yuav tsum tau ua kom tau raws li kev cai, nyob rau hauv txoj kab nrog GB5237.2-2004 "aluminium alloy tsev profiles ib feem 2: anodizing, coloured profiles."
4. Qhov zoo ntawm qhov profile yog ua raws li cov cai ntawm GB5237.2-2004. Cov nplaim ntawm qhov profile yuav tsum zoo huv si, thiab tsis muaj teeb meem loj xws li kab nrib pleb, chiv, pas thiab cua npuas pub.
