Cov Kev Faib Pawg Tseem Ceeb thiab Cov Lus Qhia Tshwj Xeeb
Cov Hom Tseem Ceeb:Cov pas nrig khi tau muab faib ua cov pas nrig khi ncaj thiab cov pas nrig khi kab pheeb ces kaum. Cov pas nrig khi ncaj feem ntau yog ua los ntawm φ12 puag ncig hlau, thiab muaj ob txoj hauv kev ua haujlwm: ib qho yog ua cov hlau puag ncig uas muaj 11.8 hli txoj kab uas hla nrog txoj kab uas hla tsawg dua ntawm ob qho kawg thiab tom qab ntawd xov; qhov thib ob yog ua cov hlau puag ncig uas muaj 10.6 hli txoj kab uas hla ncaj qha. Lawv feem ntau yog siv rau kev sib txuas kab rov tav ntawm cov purlins uas nyob ib sab. Cov pas nrig khi kab pheeb ces kaum feem ntau siv ua ke nrog cov struts los tsim ib lub kaw lus geometrically invariant, tsom mus rau kev txhawb nqa kev ruaj khov ntawm cov purlins raws lawv cov axis tsis muaj zog. Lawv feem ntau raug ntsia ntawm cov khoov lossis qhov chaw tshwj xeeb xws li cov ridges thiab qhov qhib ru tsev.
Cov Lus Qhia Tseem Ceeb:Cov hlau puag ncig uas muaj txoj kab uas hla ntawm 8-16 hli feem ntau siv, nrog φ12 thiab φ14 yog cov lus qhia tshwj xeeb tshaj plaws. Lub npe luv "T" ntawm cov duab kos qhia tias qee cov pas nrig khi yuav siv kev sib xyaw ua ke ntawm "φ12 + φ322.5", txhais tau tias lub plawv khi pas nrig txoj kab uas hla yog φ12, thiab lub plhaub sab nraud yog lub raj hlau puag ncig φ322.5. Rau cov ntawv thov tshwj xeeb, txawm tias cov pas nrig khi loj dua kuj muaj, nrog txoj kab uas hla txog li φ300 thiab ib qho ntev txog li 12m. Q235 hlau feem ntau siv los ua kom tau raws li qhov yuav tsum tau ua ntawm cov qauv hlau ib txwm muaj.
Cov Txheej Txheem Tseem Ceeb thiab Kev Tiv Thaiv Kev Xeb
Kev Ua Haujlwm Yooj Yim:Cov txheej txheem tseem ceeb suav nrog kev kos duab txias, kev txo qhov loj me, thiab dov xov, tso cai rau kev teeb tsa yam tsis tas vuam. Piv txwv li, cov pas nrig khi ncaj nraim raug xov ntawm ob qho kawg, thiab nrog lub txiv ntoo, kev sib txuas ruaj ntseg rau lub purlin tau ua tiav. Qhov no yooj yim thiab tso cai rau kev hloov kho qhov nruj kom ua tau raws li qhov yuav tsum tau ua kom raug ntawm lub purlin.
Kev Tiv Thaiv Kev Xeb:Cov txheej txheem feem ntau suav nrog kev kub-dip galvanizing thiab electro-galvanizing. Qee cov ntawv thov siab siv cov txheej txheem sib xyaw ua ke ntawm zinc lossis txhuas txau ua raws li kev sib khi txheej nrog xim tiv thaiv xeb. Cov txheej txheem sib xyaw no muab lub neej tiv thaiv ntev dua li ib txheej, zoo tiv taus cov av noo sab nraum zoov, nag, daus, thiab lwm yam ib puag ncig corrosive, yog li ua kom lub neej ua haujlwm ntawm cov hlua khi hauv cov tsev hlau qhib.
Cov Ntsiab Lus Teeb tsa thiab Cov Xwm Txheej Thov
Cov Lus Qhia Txog Kev Teeb Tsa:Yuav tsum tau kho qhov layout raws li qhov sib nrug ntawm kem. Rau qhov sib nrug ntawm kem hauv 6 meters, feem ntau yuav tsum tau teeb tsa ib tug pas nrig khi; rau qhov sib nrug ntau dua 6 meters, yuav tsum muaj 2-3 tug pas nrig khi. Yuav tsum tau ntxiv cov pas nrig khi ruaj khov ntawm qhov khoov. Ntawm cov kab, qhov qhib ntawm lub ru tsev, thiab lwm yam, yuav tsum tau siv cov pas nrig khi kab pheeb ces kaum thiab cov struts ua ke los hloov qhov nro mus rau lub thav duab ruaj khov, tiv thaiv kev thauj khoom ntau dhau ntawm cov purlins ib leeg. Cov pas nrig khi tsuas yog hloov qhov nro thiab yuav tsum ua haujlwm ua ke nrog cov struts uas dais kev ntxhov siab compressive los faib lub zog sab nraud ntawm cov purlins rau cov beams lossis kem.
Cov Xwm Txheej Ib Txwm Muaj:Feem ntau siv rau hauv cov tshuab ru tsev thiab phab ntsa ntawm cov chaw tsim khoom loj, cov tsev rau khoom, cov chaw ua si, thiab lwm yam tsev hlau, uas yog lub luag haujlwm rau kev kho cov purlins zoo li C thiab Z. Piv txwv li, hauv cov chaw ua haujlwm hlau portal, cov pas nrig khi ncaj yog siv los txuas tag nrho cov kab ntawm cov purlins ru tsev rau hauv ib qho tag nrho, thiab tom qab ntawd cov pas nrig khi kab pheeb ces kaum yog siv los txhawb thiab kho lawv ntawm lub roob kom tiv taus qhov kev hloov pauv lossis kev hloov pauv ntawm cov purlins los ntawm cov zog sab nraud xws li cua; nws kuj tseem siv tau rau hauv cov xwm txheej sib txawv xws li photovoltaic brackets los pab kho cov qauv bracket thiab xyuas kom meej tias muaj kev ruaj khov tag nrho.
