U-shaped bolts yog cov khoom tsis yog cov qauv uas feem ntau yog siv los kho cov kav dej xws li cov kav dej lossis cov ntawv hlaws xws li cov nplooj nplooj ntoo. Vim nws cov duab U-shaped, nws tuaj yeem ua ke nrog cov txiv ntseej, yog li nws tseem hu ua U-shaped bolts lossis caij bolts.
Cov duab tseem ceeb ntawm U-shaped bolts muaj xws li semicircle, square txoj cai kaum, daim duab peb sab, oblique daim duab peb sab thiab lwm yam. U-shaped bolts nrog cov khoom sib txawv, qhov ntev, txoj kab uas hla thiab qib zog tuaj yeem xaiv tau raws li qhov sib txawv siv thiab cov kev xav tau.
Nws muaj ntau yam kev siv, feem ntau yog siv hauv kev tsim kho thiab kev teeb tsa, cov khoom siv sib txuas, tsheb thiab nkoj, txuas hniav, tunnels, railways thiab lwm yam. Ntawm cov tsheb thauj khoom, U-bolts yog siv los txhim kho lub tsheb qhov chaw thiab ncej. Piv txwv li, nplooj nplooj hlav txuas nrog U-shaped bolts.
Bolt qib xaiv.
Bolt qib feem ntau muab faib ua ob hom: siab zog bolts thiab zoo tib yam bolts. Thaum xaiv cov bolt qib, nws yuav tsum tau txiav txim siab raws li qhov kev thov ib puag ncig, quab yuam yam ntxwv, cov khoom siv raw thiab lwm yam.
1. Los ntawm kev xav ntawm cov khoom siv raw: cov bolts muaj zog yog ua los ntawm cov ntaub ntawv muaj zog, xws li 45 # steel, 40 boron steel, 20 manganese titanium boron steel. Ordinary bolts feem ntau yog ua los ntawm Q235 steel.
ob.. Nyob rau hauv cov nqe lus ntawm lub zog qib, feem ntau siv lub zog siab bolts yog 8.8s thiab 10.9s, ntawm uas 10.9S yog feem ntau siv. Cov qib zog ntawm cov bolts zoo tib yam yog 4.4, 4.8, 5.6 thiab 8.8.
3. Los ntawm qhov pom ntawm cov yam ntxwv ntawm cov neeg kho tshuab: lub zog muaj zog bolts siv ua ntej nro thiab hloov lwm lub zog los ntawm kev sib txhuam. Ntawm qhov tod tes, qhov zoo tib yam ntsia liaj qhov rooj txuas yog nyob ntawm qhov kev sib txhuam ntawm cov ntsia liaj qhov rooj thiab lub siab ntawm lub qhov phab ntsa kom hloov lub zog shear, thiab lub zog ua ntej yog me me thaum zawm cov txiv ntoo. Yog li ntawd, cov yam ntxwv ntawm kev siv tshuab yuav tsum tau xav txog hauv daim ntawv thov.
4. Los ntawm qhov kev pom ntawm kev siv: bolted kev twb kev txuas ntawm lub ntsiab ntawm lub tsev qauv yog feem ntau txuas nrog high-strength bolts. Ordinary bolts tuaj yeem rov qab siv tau, thaum lub zog muaj zog bolts tsis tuaj yeem rov qab siv tau thiab feem ntau siv rau kev sib txuas mus tas li.
Nyob rau hauv ib lo lus, thaum xaiv cov specification thiab bolt qib ntawm U-zoo li tus ntsia liaj qhov rooj, peb yuav tsum xav txog cov khoom, qib zog thiab kev nyuaj siab cov yam ntxwv ntawm lub ntsia liaj qhov rooj raws li qhov xav tau tiag tiag thiab siv ib puag ncig, thiab xaiv cov khoom tsim nyog kom ua tiav cov txiaj ntsig ntawm kev ruaj ntseg, stability thiab kev cia siab.
