Koj pom ib qho spec zoo li 10U1 4U5 16 square U-bolt pov ib ncig, thiab yog tias koj tsis sib sib zog nqus hauv cov yeeb nkab kev txhawb nqa lossis cov txheej txheem bracing, nws kuj yuav yog hieroglyphics. Qhov tseeb yog, txawm tias qee cov txiv neej muaj caij nyoog tau poob mus rau qhov xav tias 16 tau hais txog txoj kab uas hla-nws tsis yog. Qhov ntawd feem ntau yog qhov square dimension, qhov dav thoob plaws lub tiaj tiaj ntawm U-bolt qhov khoov. Cov nqaij tiag tiag yog nyob rau hauv 10U1 thiab 4U5, uas feem ntau yog tus tswv lossis cheeb tsam coding rau kev ntsuas kev ntsuas thiab qhov loj me. Cia peb tawg qhov koj tab tom nrhiav tiag tiag thaum ib tus neeg nug txog qhov no.

Decoding Alphanumeric Soup

Zoo, yog li 10U1 thiab 4U5. Hauv ntau phau ntawv teev npe, tshwj xeeb tshaj yog los ntawm cov chaw tsim khoom loj xws li Tuam Tshoj lub nroog Yongnian, U qhia txog U-bolt series. Tus lej ua ntej feem ntau cuam tshuam nrog chav kawm ua yeeb yam lossis style. 10U1 tuaj yeem qhia txog cov haujlwm hnyav dua, tej zaum rau cov kav dej loj dua lossis siab dua seismic loads, thaum 4U5 tej zaum yuav yog cov sib dua. Qhov 1 thiab 5 yog cov kev hloov kho lossis cov kab lis kev cai sub-style. Koj yuav tsis pom qhov no hauv ASTM cov qauv; nws yog Hoobkas-hais lus. Kuv nco qab rub kuv cov plaub hau tawm hla-hais txog 6U3 los ntawm ib tus neeg muag khoom nrog CL-150 los ntawm lwm tus-tawm tias lawv tau ua haujlwm zoo ib yam, tsuas yog cov ntawv sib txawv. Ib txwm, ib txwm nug txog qhov kos duab kos duab.

Lub 16 square yog clearer. Qhov no qhia txog lub square U-bolt, qhov twg qhov khoov yog qhov tseeb 90-degree lub kaum ntse ntse, tsis sib npaug. Qhov 16 yog qhov A qhov dav, sab hauv dav ntawm U, feem ntau hauv millimeters. Yog li, nws yog 16 hli ntawm sab hauv ntawm ib txhais ceg mus rau sab hauv ntawm lwm yam. Qhov no yog ib qho tseem ceeb rau kev haum ntawm ib lub teeb los yog channel. Ib qho yuam kev feem ntau yog xaj 16mm square U-bolt kom clamp lub 16mm tuab-nws yuav tsis haum. Koj xav tau kev tshem tawm, feem ntau yog ob peb hli ntxiv.

Dab tsi ploj ntawm no? Cov ceg ntev (L dimension), xov loj thiab suab (piv txwv li, M12 x 1.75), cov khoom siv (cov pa roj carbon steel, kub-dip galvanized, 304/316 stainless), thiab ua tiav. alphanumeric code tsis tshua muaj xws li tag nrho cov ntawd. Nws yog qhov pib taw tes, tsis yog tag nrho spec. Kuv kawm qhov no txoj kev nyuaj ntawm txoj haujlwm cog dej; peb tau txais 10U1 bolts ntawm qhov chaw, tab sis lawv yog cov hlau dawb thaum peb xav tau kub-dip galv. Tag nrho cov khoom xa tuaj tau raug tsis lees paub.

Tseem ceeb Dimensions Lawv tsis qhia koj

Leg ntev yog txhua yam rau kev teeb tsa. Yog tias ob txhais ceg luv dhau, koj cov txiv ntoo yuav tsis koom nrog. Ntev dhau lawm, thiab koj tau nkim cov khoom siv thiab muaj peev xwm cuam tshuam kev nruj - ntev, nyias ceg tuaj yeem khoov hauv qab torque. Rau ib lub square U-bolt, koj kuj xav tau B qhov ntev, sab hauv qhov siab los ntawm hauv qab ntawm qhov khoov mus rau qhov pib ntawm cov xov. Qhov no txiav txim siab npaum li cas cov ntaub ntawv uas koj muaj peev xwm encompass. Ib txoj cai dav dav: rau cov yeeb nkab clamp, koj qhov B qhov ntev yuav tsum siab dua li cov yeeb nkab OD. ntxiv rau qhov tuab ntawm koj lub eeb lossis lub cushion, ntxiv rau qhov sib txawv rau cov txiv ntoo thiab lub tshuab ntxhua khaub ncaws.

Xov specification yog lwm pitfall. 16 square tsis hais dab tsi txog tus pas nrig txoj kab uas hla. Nws tuaj yeem yog M10, M12, lossis txawm tias M8 threading ntawm 16mm square khoov. Lub load muaj peev xwm hinges rau qhov no. Rau ib cev clamp Kev ruaj ntseg 4-nti lub sijhawm 40 kab, ib qho M10 xov ntawm 10U1 ntsia liaj qhov rooj tej zaum yuav qis dua rau kev thauj khoom dynamic. Koj xav tau lub zog tensile thiab cov ntaub ntawv pov thawj load. Reputable manufacturers, zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd. raws li qhov loj Yongnian ntau lawm puag, feem ntau muab cov kab kos. Lawv lub site, Zitaifasteners.com, muaj cov nplooj ntawv tsim nyog uas koj tuaj yeem txheeb xyuas cov lej sib txawv ntawm cov khoom siv tshuab tiag tiag.

Cov khoom siv thiab ua tiav tsis yog cov ntsiab lus tseem ceeb. Hauv cov nroj tsuag tshuaj, 4U5 ntsia liaj qhov rooj zoo dua yog 316 stainless. Hauv daim ntawv thov HVAC ntug hiav txwv, kub-dip galvanized rau ASTM A153 yog tsis sib tham. Lub coding 10U1 tej zaum yuav muaj cov khoom siv tsis raug, tab sis koj yuav tsum paub meej. Kuv tau pom U-bolt coj los txhais tau tias yog generic, galvanized los ntawm kev yuav khoom, ua rau ua rau ntxov ntxov corrosion tsis ua hauj lwm ntawm qhov chaw nres tsheb qhov project. Cov spec yuav tsum qhia meej meej lub xeev cov ntaub ntawv qib thiab txheej.

Daim ntawv thov tiag-lub ntiaj teb thiab Load Considerations

Yog li, koj siv qhov no rau cov yeeb nkab clamp sib dhos. U-bolt tsuas yog ib feem. Koj muaj lub eeb (cov khoom uas cradles cov yeeb nkab), cov txiv ntseej, thiab feem ntau ib lub phaj rov qab los yog channel. U-bolt txoj haujlwm yog los tsim lub zog clamping yam tsis muaj deforming. Lub square U-bolt, zoo li qhov no 16 square, zaum ntws tawm ntawm lub teeb square, tiv thaiv kev sib hloov-ib puag ncig U-bolt tuaj yeem qee zaum tig thaum nruj, uas yog npau suav phem hauv qhov chaw nruj.

Cov lej cim 10U1 vs. 4U5 yuav muaj feem cuam tshuam rau kev ntaus nqi. Hauv kuv qhov kev paub dhau los, tus lej loj dua feem ntau txhais tau hais tias txoj kab uas hla ntawm tus pas nrig thiab lub vojvoog khoov hnyav dua, tsim los rau ntau dua seismic lossis thermal txav loads. Koj tsis tuaj yeem pauv lawv xwb. Ntawm txoj haujlwm retrofit xyoo tas los, peb hloov 4U5 bolts nrog 10U1 ntawm lub voj kab txuas ntxiv, tab sis peb yuav tsum tau hloov kho tag nrho lub eeb los ua ke, vim tias qhov hnyav dua yuav tsum muaj lub eeb tuab dua los faib cov khoom kom zoo ntawm cov yeeb nkab rwb thaiv tsev.

Torque tseem ceeb heev. Tshaj-torquing ib square U-bolt tuaj yeem ntxhov siab qhov khoov, tsim kom muaj qhov tawg. Hauv qab-torquing, thiab koj cov yeeb nkab plam. Tus nqi torque nyob ntawm cov xov loj, suab, thiab cov khoom siv. Tsis muaj ib qho loj-haum-tag nrho. Koj xav tau lub chaw tsim khoom lub rooj torque rau cov khoom lag luam tshwj xeeb. Cov rooj dav dav tau txais koj hauv qhov chaw ua si tab sis tuaj yeem tawm los ntawm 20%.

Sourcing thiab Gotcha Factors

Thaum koj tab tom nrhiav ib yam dab tsi nrog tus lej zoo li no, koj yuav muaj feem cuam tshuam nrog tus neeg muag khoom tshwj xeeb. Nws them ncaj qha mus rau lub chaw tsim khoom nrog kev txhawb nqa engineering. Ib lub tuam txhab zoo li Handan Zitai Fastener, muab nws qhov chaw nyob rau hauv plawv ntawm Tuam Tshoj txoj kev lag luam fastener nrog cov khoom logistics txuas, feem ntau muaj cov lis dej num no qhia txog cov ncauj lus ntxaws ntxaws. Qhov yooj yim yog nyob ntawd, tab sis lub luag haujlwm yog nyob ntawm koj los muab tag nrho cov ntsiab lus ntawm daim ntawv thov.

Qhov loj gotcha yog kam rau ua. A 16mm square dimension tuaj yeem muaj +/- 1mm kam rau ua. Yog tias koj cov channel steel yog nruj 16 hli, lub ntsia liaj qhov rooj ntawm 15 hli yuav xoob, thiab ib qho ntawm 17 hli yuav tsis haum. Rau cov ntawv thov tseem ceeb, koj yuav tsum qhia kom meej qhov kev zam nruj dua, uas yuav txav koj los ntawm cov khoom lag luam mus rau qhov kev cai khiav. Lub sij hawm ua ntej thiab cov nqi hloov.

Lwm qhov kev ceeb toom: square U-bolts, tshwj xeeb tshaj yog nyob rau hauv qhov ntau thiab tsawg, tuaj yeem muaj qhov sib txawv me ntsis los ntawm qhov zoo meej 90-degree khoov vim lub forging thiab txias txheej txheem. Nws tsim nyog thov rau qhov ncaj/camber kam rau ua. Kuv yuav tsum tau xa rov qab ib pawg uas ob txhais ceg splayed los ntawm 3 degrees, ua rau nws tsis yooj yim sua kom tau cov txiv ntoo pib sib npaug. Ib tus neeg muag khoom zoo yuav kuaj xyuas qhov no.

Rub Txhua Tus Ua Ke

Yog li, rov qab mus rau Nws yog cov lus nug tsis tiav. Txhawm rau qhia nws kom raug, koj yuav nthuav nws mus rau ib yam dab tsi xws li: Square U-bolt, Series 10U1 (los yog 4U5), rau hnyav / lub teeb lub luag haujlwm yeeb nkab clamp. Sab hauv dav (A): 16mm. ceg ntev (L): [piv txwv li, 120mm]. Xov: [piv txwv li, M12 x 1.75]. Khoom siv: [piv txwv li, Qib 8.8 steel]. Ua tiav: [piv txwv li, Kub-dip galvanized]. Yuav tsum tau siv nrog sib xws eeb rau yeeb nkab OD. [X].

Cov lej series yog luv luv rau cov neeg paub txog cov khoom kab. Rau txhua tus, nws yog ib qho cuab yeej. Ib txwm deconstruct nws mus rau hauv lub cev qhov ntev thiab kev ua tau zoo. Siv cov cai raws li kev siv thaum tham nrog koj tus neeg muag khoom, tab sis tsis yog ib qho kev qhia tshwj xeeb ntawm daim duab lossis PO.

Thaum kawg, tau txais txoj cai U-Ntsia yog hais txog kev nkag siab qhov system nws yog ib feem ntawm. Lub bolt tsis ua haujlwm hauv kev sib cais. Qhov 16 square dimension yuav tsum ua si zoo nrog koj cov kev txhawb nqa hlau, qhov ntsuas 10U1 yuav tsum phim koj cov lej suav, thiab cov khoom yuav tsum muaj sia nyob koj ib puag ncig. Nws yog ib feem me me, tab sis qhia meej tias nws tsis raug tuaj yeem ua rau ntau qhov kev rov ua haujlwm - ntseeg kuv, Kuv tau ua tus txiv leej tub uas muaj kev cuam tshuam rau hauv nag, sim ua kom tsis raug ntsia hlau.
