Kev piav qhia ntau lawm
Steel qauv torsion shear bolt yog lub zog muaj zog ntsia liaj qhov rooj thiab kuj yog hom qauv tivthaiv. Steel structural bolts tau muab faib ua torsion shear high-strength bolts thiab loj hexagonal high-strength bolts. Loj hexagonal high-strength bolts muaj nyob rau qib high-strength ntawm zoo tib yam screws, thaum torsion shear high-strength bolts yog ib qho kev txhim kho hom loj hexagonal high-strength bolts rau kev tsim kho zoo dua. Qhov loj hexagonal steel qauv ntsia liaj qhov rooj muaj ib lub ntsia liaj qhov rooj, ib tug txiv ntseej, thiab ob lub tshuab ntxhua khaub ncaws. Twist shear steel structural bolts muaj xws li ib lub ntsia liaj qhov rooj, ib lub txiv ntoo, thiab ib lub tshuab ntxhua khaub ncaws. Ntawm cov qauv hlau dav dav, qhov yuav tsum tau muaj cov qauv steel bolts yog qib 8.8 lossis siab dua, nrog rau qib 10.9 thiab 12.9, tag nrho cov no yog cov khoom siv muaj zog steel bolts. Qee zaum, bolts ntawm cov qauv hlau tsis xav tau electroplating.
Qhov ntev ntawm lub torsion shear high-strength bolt yog qhov ntev ntawm qhov kev txhawb nqa qis ntawm lub taub hau ntsia hlau mus rau qhov txiav ntawm qhov kawg ntawm cov ntsia hlau. Lub torsion shear high-strength bolt muaj lub paj paj taub hau ntawm tus Tsov tus tw ntawm cov ntsia hlau, thiab ib qho tshwj xeeb wrench yog siv los zawm cov txiv ntoo thaum siv. Lub torque thaum lub taub hau paj tawg tawg yog tus qauv torque. Lawv txhua tus muaj kev sib txhuam hom siab zog bolts thiab hloov tau, tab sis torsion shear type high-strength bolts tsis xav tau torque xam thiab yooj yim los xyuas kom meej torque, uas tuaj yeem zam qhov tshwm sim ntawm qhov tsis muaj peev xwm los xyuas kom meej qhov kawg nruj torque vim kev suav. yuam kev los yog siv cov wrenches zoo tib yam es tsis txhob torque wrenches.
Qhov loj ntawm lub taub hau hexagonal ntawm cov qauv steel loj hexagonal ntsia liaj qhov rooj kev twb kev txuas khub yog txawv ntawm cov dav dav sab nrauv hexagonal ntsia liaj qhov rooj txuas khub. Qhov loj ntawm lub taub hau hexagonal ntawm cov qauv hlau loj hexagonal ntsia liaj qhov rooj txuas khub yog loj dua li ntawm cov khoom siv hexagonal ntsia liaj qhov rooj. Yog li ntawd, steel qauv loj hexagonal ntsia liaj qhov rooj txuas khub kuj tseem hu ua steel qauv loj hexagonal ntsia liaj qhov rooj txuas khub. Cov qauv hlau loj hexagonal ntsia liaj qhov rooj txuas txuas yog tsuas yog siv rau kev tsim kho ntawm cov tsev lag luam thiab pej xeem, tsheb ciav hlau txuas hniav, txoj kev loj choj, cov kav dej txuas hniav, ntauwd thiab mast lug, boiler thav ntawv, boiler steel qauv, loj-span industrial nroj tsuag, high-rise. civil vaj tse, ntau yam yees, lub teeb steel qauv, lifting machinery, thiab lwm yam steel qauv kev twb kev txuas cov tsev.
Txhua txheej steel qauv loj hexagonal ntsia liaj qhov rooj kev twb kev txuas khub muaj xws li ib tug high-zog steel qauv loj hexagonal ntsia liaj qhov rooj kev twb kev txuas khub GB/T 1228, ib tug high-strength txiv ntseej GB / T1229 rau steel lug, thiab ob high-strength washers GB / T1230 rau hlau. cov qauv, tag nrho cov uas yog tsim nyob rau hauv tib batch. Cov qauv rau loj hexagonal ntsia liaj qhov rooj sib txuas khub hauv steel qauv muaj xws li: GB / T1228-2006 Steel Structure Loj Hexagonal Bolt Connection Pairs, GB / T1229-2006 High Strength Loj Hexagonal Ceev rau Steel Structures, GB / T1230-2006 High Strength Washer Cov qauv, thiab GB / T1231-2006 Cov Txheej Txheem Txheej Txheem rau Loj Hexagonal Bolt Kev Txuas Pair, Loj Hexagonal Ceev, thiab Washers rau Cov Qauv Hlau.
Thaum sib sau ua ke ntawm kev sib txuas ntawm cov hexagonal bolts loj hauv cov qauv hlau, lub chamfered sab ntawm lub tshuab ntxhua khaub ncaws hauv qab lub taub hau ntsia liaj qhov rooj yuav tsum fim lub taub hau ntsia liaj qhov rooj; Thaum tsim cov kev sib txuas ntawm cov loj hexagonal bolts nyob rau hauv cov qauv steel, yuav tsum tau ib tug torque ciaj ntswj, uas yuav tsum tau ib tug loj kev khiav hauj lwm qhov chaw thiab yuav tsum tau ua kom tiav nyob rau hauv ob qhov chaw: thawj zaug zawm thiab zaum kawg zawm. Kev tsim kho yog qhov nyuaj dua piv rau torsion shear bolts; Kev tshuaj xyuas zoo kuj tseem yuav tsum tau tshuaj xyuas lub zog, xav tau cov cuab yeej tshaj lij thiab cov neeg soj ntsuam zoo.
