Strut channel yob txoj kev tshuab qauv:
Muaj ob lub ntsiab ntawm kev txhawb nqa rau kab pheeb ces kaum bracing ntawmstrut channel yob txoj kev tshuab, uas yog kev txhawb nqa nruj thiab kev txhawb nqa yooj yim. Txij li cov kev txhawb nqa nruj yuav tsum tau tiv thaiv ob qho tib si nruj thiab siab tib lub sijhawm, cov khoom siv xws li cov kav hlau galvanized feem ntau yog siv rau hauv daim ntawv ntawm kev txhawb nqa ib leeg. Kev txhawb nqa yooj yim yog txawv ntawm kev nruj. Nws tsuas tuaj yeem tiv taus lub zog tensile, yog li cov hlau txuas feem ntau raug xaiv kom muaj nyob rau hauv daim ntawv sib luag ntawm ob sab.
Daim ntawv txhawb nqa ntawm strut channel yob txoj kev tshuab kuj tuaj yeem muab faib ua lateral kev txhawb nqa thiab kev txhawb nqa ntev, uas tau muab faib raws li lawv txoj haujlwm. Lateral kev txhawb nqa feem ntau yog siv los tiv thaiv cov nyhuv ntawm lateral kab rov tav seismic quab yuam, thiab kev txhawb nqa longitudinal yog siv los tiv thaiv longitudinal quab yuam.
Installation ntawmstrut channel yob txoj kev tshuab
1. Qhov nruab nrab kab rov tav installation nrug ntawm cov yeeb nkab hanging bracket yog 2000mm, thiab qhov sib txuas ruaj ruaj yuav tsum tau teeb tsa raws li cov qauv tsim.
2. Lub raj xa dej los tiv thaiv seismic kev txhawb nqa thiab cov hangers yuav tsum tsis txhob txwv qhov kev hloov pauv los ntawm thermal expansion thiab contraction ntawm cov kav dej. Rau cov kav dej uas muaj qhov kub thiab txias sib txawv thiab deformation, tus neeg muag khoom yuav tsum muab kev txhawb nqa tshwj xeeb zawv zawg (dov) thiab kev txhawb nqa ruaj khov.
Seismic kev txhawb nqa yuav tsum tau teem rau ntawm ob qho kawg ntawm txhua kab kab rov tav txoj kab ncaj nraim, thiab kev txhawb nqa seismic yuav tsum tau teeb tsa hauv 0.6m ntawm qhov hloov pauv ntawm cov kav dej kab rov tav; Thaum qhov sib nrug ntawm kev txhawb nqa seismic ntau dua qhov tsim qhov sib txawv, kev txhawb nqa seismic yuav tsum tau muab tso rau hauv nruab nrab. (Lub ntsiab yeeb nkab nrog lub nominal txoj kab uas hla ntau dua los yog sib npaug li 50 hli rau cov roj tua hluav taws tua cov yeeb nkab tau raug tshem tawm. Yam tsawg kawg yog ib qho kev txhawb nqa los tiv thaiv sway yuav tsum tau muab tso rau hauv cov lus qhia ntsug thiab kab rov tav. - sway txhawb yuav tsum tau nruab.)
3. Tsis txhob txhim kho seismic kev txhawb nqa thiab hangers ntawm cov khoom tsis yog cov qauv, xws li cov phab ntsa, thiab lwm yam.
4. Thaum qhov hnyav ntawm cov khoom siv hauv cov raj xa dej ntau dua 25kg, kev txhawb nqa ntev thiab sab nraub qaum yuav tsum tau nruab.
5. Kab rov tav cov kav dej yuav tsum tau muab cov kev txhawb nqa sab nraud hauv 600mm los ntawm cov kav dej ntsug. Kev txhawb nqa seismic yuav tsum tau muab rau cov kav dej ntsug ntau dua 0.15m los ntawm hauv av.
Kev txhawb nqa seismic thiab hangers yuav tsum tau muab rau cov kav dej kab rov tav ntawm ob qho kawg ntawm kev teeb tsa ntawm cov khoom siv tau yooj yim lossis cov pob qij txha txuas ntxiv.
