Thaum kho kom zoo nkauj hauv tsev, feem ntau yuav tsum tau sivU-boltsrau fixation. Yog li ntawd, thaum xaiv U-bolts, nws yog ib qho tsim nyog yuav tsum nkag siab txog lawv cov kev qhia tshwj xeeb, qhov ntev, thiab cov kev xav tau tshwj xeeb txhawm rau xaiv U-bolt uas haum tshaj plaws. Tom ntej no, tsab xov xwm no yuav qhia txog cov kev qhia tshwj xeeb, qhov ntev, thiab kev xav tau ntawm U-bolts rau koj siv.
1, Specifications thiab qhov ntev ntawm U-bolts
U-bolts tau muab faib ua ntau yam tshwj xeeb thiab qhov ntau thiab tsawg raws li lawv lub hom phiaj thiab txoj kab uas hla ntawm cov yeeb nkab ruaj khov. Tus qauv cim piv txwv rau U-bolts nrog ib txoj kab uas hla ntawm 25mm yog raws li nram no:
-Cov cim rau ib tug pa U-bolt nrog ib tug tsau txheej kab D0 ntawm 25mm yog: U-bolt 25JB/ZQ4321-97;
-Cov cim ntawm U-bolt nrog ib txoj kab nruab nrab ruaj D0 ntawm 25mm thiab galvanized nto yog: U-bolt 25-ZnJB/ZQ4321-97.
2, Kev xav tau rau U-bolts
1. Ua raws li cov qauv tsim nyog
Cov txheej txheem dav dav ntawm U-bolts yuav tsum ua raws li cov kev cai ntawm lub teb chaws tus qauv GB2314-85 "Cov Txheej Txheem Txheej Txheem rau Hluav Taws Xob Hluav Taws Xob".
2. Cov khoom siv thiab fasteners
(1) U-bolts yuav tsum tau tsim nrog hlau nrog lub zog tensile tsis tsawg tshaj 372.5N / mm2 (372.5MPa) raws li cov kev cai ntawm lub teb chaws tus qauv GB700-79 "Technical Conditions for Ordinary Carbon Structural Steel" .
(2) Cov txiv ntseej yuav tsum tau ua raws li cov kev cai ntawm lub teb chaws tus qauv GB41-76 "Hexagonal txiv ntseej(Raug)".
(3) Kev muag khoom kaw yuav tsum tau ua raws li kev lag luam tus qauv SD26-82 "Kev Muag Khoom Kawg".
3. Tsis txo qis txoj kab uas hla
Lub threaded ib feem thiab tus pas nrig ntawm U-bolts yuav tsum tsis txhob raug txo nyob rau hauv txoj kab uas hla los xyuas kom meej lub firmness ntawm fixation.
4. Siv load
Qhov tso cai thauj khoom rau U-bolts yuav tsum tsis pub tshaj qhov muaj nuj nqis teev hauv Table 3 kom muaj kev nyab xeeb thaum siv.
Hauv cov ntsiab lus, thaum yuav U-bolts, nws yog ib qho tsim nyog yuav tsum nkag siab txog lawv cov kev qhia tshwj xeeb, qhov ntev, thiab kev xav tau. Los ntawm kev xaiv U-bolts uas ua tau raws li qhov yuav tsum tau ua, nws muaj peev xwm ua kom muaj kev txhim kho, kev nyab xeeb, thiab kev ntseeg siab ntawm kev kho kom zoo nkauj hauv tsev.
