Lag bolts, tseem hu ua lag screws, yog lub luag haujlwm hnyav tsim los koom nrog ntoo ua ke. Lawv yog cov cwj pwm los ntawm lawv cov lus qhia taw qhia thiab cov xov ntxhib, uas tso cai rau lawv mus tom tob rau hauv ntoo, tsim kom muaj zog thiab ruaj ntseg tuav. Phau ntawv qhia no tshawb txog txhua yam koj xav paub ua ntej koj yuav lag bolts rau ntoo, suav nrog hom, qhov ntau thiab tsawg, cov ntaub ntawv, cov txheej txheem kev teeb tsa, thiab cov khoom siv los txiav txim siab thaum koj yuav khoom.Kev nkag siab Lag Bolts Dab tsi yog Lag Bolts?Lag bolts yog cov ntsia hlau loj feem ntau siv los khi cov khoom hnyav, tshwj xeeb yog ntoo, rau lwm cov ntaub ntawv, suav nrog ntoo, pob zeb, lossis hlau. Tsis zoo li lub tshuab screws uas xav tau cov txiv ntoo, lag bolts tsim lawv tus kheej mating xov nyob rau hauv pre-drilled qhov. Lub sij hawm 'lag' yog hais txog lawv cov keeb kwm siv hauv kev fastening ntoo lags siv hauv lub thoob ua, yog li lub npe tau daig txawm tias siv dav hauv lwm daim ntawv thov.Kev xav ntawm Lag Bolt Kev nkag siab txog qhov sib txawv ntawm lub lag luam bolt tuaj yeem pab koj xaiv qhov zoo rau koj qhov project: Lub taub hau: Lub taub hau yog ib feem uas tau tsav mus rau hauv cov khoom. Hom taub hau muaj xws li hex, square, thiab round. Shank: Qhov tsis muaj xov ntawm lub bolt hauv qab lub taub hau. Xov: Cov ntxhib, taw tes xov uas tuav cov ntoo. Point: Lub taub hau ntse uas pab hauv kev pib lub bolt. Hom Lag BoltsHex Lub Taub Hau Lag BoltsHex taub hau lag bolts yog hom ntau tshaj plaws. Lawv tau yooj yim tsav nrog ib tug ciaj ntswj los yog lub qhov (socket).Square Head Lag BoltsSquare lub taub hau lag bolts muab ib tug ruaj ntseg tuav ntau dua rau tus ciaj ntswj tab sis tsis tshua muaj ntau tshaj hex hau. Lawv feem ntau siv rau hauv kev tsim kho qub lossis kev kho dua tshiab.Round Head Lag BoltsRound lub taub hau lag bolts, tseem hu ua carriage bolts, yog siv rau kev ua tiav zoo dua thiab feem ntau siv nrog lub tshuab ntxhua khaub ncaws.Xaiv qhov loj thiab cov khoom txiav txim siab qhov tseeb Qhov loj ntawm lub lag bolt koj xav tau nyob ntawm lub thickness ntawm cov ntaub ntawv uas koj tab tom koom thiab lub load nws xav tau. Nov yog cov lus qhia dav dav: Ntev: Lub ntsia liaj qhov rooj yuav tsum ntev txaus kom nkag mus rau yam tsawg kawg yog ib nrab ntawm lub thickness ntawm cov khoom tau txais. Piv txwv li, yog tias koj tab tom fastening ib 2-nti tuab daim ntoo rau lwm tus, lub ntsia liaj qhov rooj yuav tsum muaj tsawg kawg yog 3 nti ntev (2 nti + 1 nti). Txoj kab uas hla: Txoj kab uas hla yog nyob ntawm qhov load. Thicker bolts muab lub zog tuav ntau dua. Feem ntau cov kab uas hla ntawm 1/4 nti mus rau 3/4 nti.Materials: Hlau, Stainless hlau, thiab MoreLag bolts muaj nyob rau hauv ntau yam ntaub ntawv, txhua tus muaj nws tus kheej zoo: Hlau: Txheem steel lag bolts yog tsim rau kev siv dav. Feem ntau zinc plated rau corrosion kuj. Stainless hlau: Stainless hlau lag bolts muab zoo heev corrosion kuj, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov thiab marine ib puag ncig. Galvanized hlau: Galvanized steel lag bolts yog coated nrog zinc los muab kev tiv thaiv corrosion. Lawv yog ib qho kev xaiv zoo rau cov haujlwm sab nraum zoov uas tsis muaj steel hlau tsis tsim nyog.

Qhov no tiv thaiv cov ntoo los ntawm kev sib cais thiab ua kom yooj yim installation. Lub qhov pilot yuav tsum me ntsis me dua lub shank ntawm lub bolt tab sis loj dua cov xov core. Nrog rau daim ntawv qhia txog qhov loj me me raws li koj lub bolt txoj kab uas hla thiab hom ntoo. Kauj Ruam 2: Tsav lub Lag Bolt Siv lub ciaj ntswj los yog lub qhov (socket) tsav lub lag bolt mus rau hauv lub qhov ua ntej drilled. Thov tsis tu ncua, txawm siab. Tsis txhob nruj dhau, uas tuaj yeem rub cov xov los yog ua rau cov ntoo puas. Siv lub tshuab ntxhua khaub ncaws hauv qab lub taub hau tuaj yeem faib lub siab thiab tiv thaiv lub taub hau ntawm lub taub hau los ntawm kev nkag mus rau hauv ntoo. Kauj Ruam 3: Ua kom ruaj ntseg HoldTest qhov kev sib txuas kom ruaj ntseg. Yog hais tias lub bolt tig dawb, nws yuav raug stripped. Nyob rau hauv rooj plaub no, tej zaum koj yuav tau siv ib tug ntev los yog tuab ntsia liaj qhov rooj, los yog ntxig ib tug ntoo plug thiab sim dua.Kev siv ntawm Lag Bolts nyob rau hauv WoodworkingDeck ConstructionLag bolts yog feem ntau siv nyob rau hauv lawj kev tsim kho kom ruaj ntseg ledger board rau lub tsev thiab fasten lub lawj ncej ua ke.Framing thiab ntoo FramingLag bolts yog ib qho tseem ceeb rau kev koom tes framing ntoo loj thiab tej yaam num.
