Steel qauv fasteners yog ntsia liaj qhov rooj sib dhos - sib tw bolts, txiv ntseej, thiab cov tshuab ntxhua khaub ncaws - tsim kom nruj txhua yam thiab cov qauv kev nyab xeeb rau kev nyab xeeb- kev sib txuas tseem ceeb hauv cov tsev steel, txuas hniav, thiab cov kav hlau txuas. Ob hom kev sib txuas siv tau: bearing- hom, qhov twg bolts dais tiv thaiv daim hlau txuas (thib ob framing, purlins), thiab plam- tseem ceeb, qhov twg ua ntej-tensioned bolts clamp ob leeg nto tiv thaiv kev thim rov qab lossis qaug zog loads (thawj kab teeb - rau-kem txuas). Ua ntej-tensioning yog ua tiav los ntawm torque-tswj lossis twist{10}}tawm bolts (F1852).

 

Cov qauv muaj xws li ASTM F3125 (A325 / A490 / F1852 hnyav hex qauv bolts), F1554 ( thauj tog rau nkoj bolts), EN 14399, thiab GB / T 1228-1231. Qib ntau ntawm 4.8 txog 10.9 / 12.9. Txheej yuav tsum sib npaug qib thiab ib puag ncig: kub-dip galvanizing txog li 8.8 (kev tiv thaiv corrosion), dacromet / mechanical galvanizing rau 10.9+ (kev tiv thaiv hydrogen embrittlement).

 

 

 

GNEE tsim cov txheej txheem bolt sib dhos rau plaub tus qauv hauv qab no. Txhua tus qauv tswj hwm lub lag luam hauv cheeb tsam tshwj xeeb - qib tsis hloov pauv. Siv cov ntaub ntawv no kom phim koj qhov project specification rau tus qauv thiab qib raug.
