Ntev npaum li cas yog expansion bolt hooks? 

Cia peb ua tiag tiag, thaum ib tug neeg nug txog kev ua haujlwm ntev ntawm kev nthuav dav bolt nuv, lawv feem ntau pom cov khoom pheej yig zinc-plated los ntawm lub khw muag khoom kho vajtse uas ua tsis tau rau lawv lub lis piam dhau los. Cov lus nug nws tus kheej yuav luag dav dhau, tab sis qhov ntawd yog qhov kev sib tham yuav tsum pib - los ntawm kev nthuav tawm qhov ruaj khov txhais tau li cas ntawm qhov chaw ua haujlwm, tsis yog hauv phau ntawv teev npe.

Nws Tsis Yog Ib Leeg Hais Txog Hook

Feem ntau qhov ua tsis tiav kuv tau pom tsis yog vim cov hlau forged nuv snapped. Nws yog kev sib yuav ntawm tus nuv, lub Kev nthuav dav Bolt lub tes tsho, thiab lub substrate uas ntog sib nrug. Koj tuaj yeem muaj qib 8 nuv, tab sis yog tias koj tsav nws mus rau hauv crumbly cinder thaiv nrog cov ntaub thaiv npog tsis zoo, tag nrho lub rooj sib txoos tsuas yog muaj zog raws li qhov tsis muaj zog txuas. Kuv tau rub tawm ntau cov hooks ua tsis tiav qhov twg lub ntsia liaj qhov rooj nws tus kheej yog pristine, tab sis phab ntsa muab txoj kev. Yog li durability tsis yog ib qho kev ntsuam xyuas ib leeg; nws yog qhov system ua haujlwm.

Cov khoom yog qhov pom tseeb thawj lim. Lub bargain-bin, dawb carbon steel hooks nrog ib tug nyias electroplated txheej? Cov no yog rau dai lub teeb cog hauv koj lub chaw nres tsheb, tej zaum. Rau txhua yam sab nraum zoov lossis hauv qab thauj khoom, koj tab tom saib kub-dip galvanized lossis stainless. Tab sis txawm nyob ntawm no, muaj ib tug ntxiab. Ib lub tsho tuab, ntxhib kub-dip tuaj yeem cuam tshuam nrog lub npoo txheej txheem ntawm Kev nthuav dav Bolt, tiv thaiv kom tsis txhob zaum. Nws yog kev lag luam tawm ntawm kev tiv thaiv corrosion thiab kev ua haujlwm tam sim ntawd.

Tom qab ntawd muaj qhov tsim ntawm tus nuv nws tus kheej. Cov uas muaj lub qhov muag kaw piv rau qhov qhib qhov rooj? Qhov sib txawv loj hauv kev ntsuas qhov ntsuas thiab tsis kam mus rau sab rub. Lub vojvoog uas lub shank ntsib lub qhov muag yog qhov tseem ceeb ntawm kev ntxhov siab. Pheej yig versions muaj ib tug ntse, machined ces kaum nyob rau hauv uas caw cracking. Ib tug smoother, forged radius kis tus load. Koj kawm pom cov ntsiab lus ntawm tes tom qab ib pliag.

Lub Installation kuj sib txawv: Qhov twg zoo Hooks mus rau tuag

Qhov no yog qhov kev tshawb xav ntsib cov pob zeb ua vaj tse, lus. Qhov loj me me laum me me tsis yog qhov kev pom zoo. Drilling ib lub qhov txawm 1 hli loj heev rau lub Kev nthuav dav Bolt lub tes tsho txhais tau tias nws yuav tsis ua tiav kev sib txhuam kom zoo. Lub ntsia liaj qhov rooj yuav xav tias nruj thaum koj torque, tab sis nws tsuas yog cov txiv ntoo jamming, tsis yog lub tes tsho nthuav. Thawj qhov load tiag tiag, thiab nws tig dawb. Kuv tau ua txhaum ntawm qhov no hauv kev nrawm, siv lub pob zeb uas hnav vim nws yog ib qho hauv kuv lub hnab. Qhov tshwm sim yog ib qho zoo kawg nkaus nuv sib dhos ua tsis muaj txiaj ntsig.

Kev ntxuav tawm yog lwm tus neeg tua neeg uas ntsiag to. Koj yuav tsum tau tshem tag nrho cov hmoov av tawm ntawm lub qhov. Yog hais tias lub tes tsho nthuav mus rau hauv cov plua plav compacted es tsis txhob siv cov masonry, lub zog tuav tuaj yeem poob los ntawm ib nrab. Tam sim no kuv siv txhuam hniav thiab lub tshuab ziab khaub ncaws, kev cai dab qhuas. Thaum ntxov hauv kuv txoj haujlwm, kuv tsuas yog tshuab rau hauv lub qhov. Tsis tsuas yog qhov ua tsis tau zoo, tab sis koj kuj tau txais lub qhov ncauj ntawm silica - ib hnub phem nyob ib puag ncig.

Torque. Txhua tus xav crank nws mus rau German spec - guttenight. Tshaj-torquing tuaj yeem strip threads, deform tus nuv lub qhov muag, los yog, dua, nthuav lub tes tsho mus rau qhov chaw uas nws tawg lub substrate los ntawm sab hauv. Kuv khaws lub calibrated torque ciaj ntswj rau qhov tseem ceeb nyiaj siv ua haujlwm installation. Rau ib lub tuam txhab xws li HANDAN ZITAI FREWER RAUG UA MOV., Ltd., uas ua haujlwm tawm ntawm Tuam Tshoj lub hauv paus tsim khoom loj, lawv yuav zoo li qhia koj tias lawv cov specs yog tsim los rau ib qho tshwj xeeb torque. Deviate los ntawm qhov ntawd, thiab koj tsis muaj qhov kev cia siab ua haujlwm. Lawv qhov chaw nyob ze ntawm txoj kev thauj loj txhais tau hais tias lawv cov khoom tsim rau ntim thiab zoo ib yam spec, uas yog qhov zoo, tab sis nws tseem tso cai rau tus neeg siv los ua raws.

Environmental Attacks: Slow Creep, Tsis Sudden Snap

Durability dhau lub sij hawm yog sib ntaus sib tua. Hauv thaj chaw ntug dej hiav txwv, txawm tias kub-dip galvanized hooks tuaj yeem pom cov xeb dawb thiab xim liab nyob rau hauv ob peb xyoos yog tias txheej txheej tsis zoo. Rau kev txhim kho sab nraum zoov mus tas li, Kuv tam sim no lean ntawm 304 lossis 316 stainless hlau hooks thiab sib piv Kev nthuav dav Bolts. Tus nqi pem hauv ntej yog siab dua, tab sis kev ua haujlwm los hloov qhov kev sib tw ua tsis tiav ntawm lub façade peb zaj dab neeg yog astronomical.

Thermal cycling yog qhov hloov maj mam. Ntawm lub hnub ci ntsa iab, cov hlau nthuav dav thiab cog lus txhua hnub. Ntau xyoo dhau los, qhov no tuaj yeem ua haujlwm maj mam ua haujlwm ntawm qhov nruab nrab-ntsia ntsia hlau xoob. Kuv pom qhov no nyob rau hauv ib tug series ntawm mounting brackets rau sab nrauv conduits. Lawv tag nrho cov me ntsis wobbly tom qab tsib lub caij ntuj sov, tsis yog vim load, tab sis vim thermal txav mus tas li. Qhov kev txhim kho tau hloov mus rau qhov sib txawv anchoring system tag nrho rau cov ntawv thov tshwj xeeb.

Kev raug tshuaj lom neeg yog niche tab sis tiag tiag. Hauv chaw nres tsheb, de-icing ntsev ntws los ntawm lub tsheb tuaj yeem ua rau lub nkoj thauj tog rau nkoj los ntawm sab saud, qhov ua tsis tiav uas koj tsis pom kom txog thaum nws nce siab. Nws tsis txaus los qhia kom meej ib co coated nuv; koj yuav tsum xav txog dab tsi yuav drip los yog txaws rau nws rau nws tag nrho cov kev pab cuam lub neej.

Case nyob rau hauv Point: Lub Cia Rack Collapse

Cov piv txwv qhia tshaj plaws tsis yog qhov sib txuas, tab sis lub hauv paus ntsiab lus zoo ib yam. Lub tsev khaws khoom tau teeb tsa lub luag haujlwm hnyav steel cia racks siv cov pob zeb loj loj rau hauv 30-xyoo-laus pob zeb hauv pem teb. Cov anchors yog saum- txee, lub installation zoo li zoo meej. Rau lub hlis tom qab, ib ntu tau tawg. Kev tshawb nrhiav pom tias cov pob zeb hauv qhov chaw ntawd, vim nws lub hnub nyoog thiab thawj qhov dej zoo, muaj lub zog compressive qis dua li cov thauj tog rau nkoj tau ntsuas rau. Cov anchors tsis poob; lawv cia ripped ib lub khob ntawm pob zeb tawm hauv pem teb. Cov durability ntawm lub fastener los ua ke yog xoom vim hais tias lub substrate muaj peev xwm yog misjudged.

Qhov no txhais ncaj qha rau hooks. Qhov zoo nkauj, tuab pob zeb qab nthab hauv lub Hoobkas qub? Nws yuav yog friable txoj cai ntawm qhov chaw. Drilling xeem qhov thiab siv lub rub-test rig rau ib tug qauv thauj tog rau nkoj yog tib txoj kev kom paub tseeb tias rau high-load daim ntaub ntawv. Nws yog ib kauj ruam feem ntau hla, piv txwv li pob zeb ua pob zeb.

Rau kev nrhiav, koj xav tau ib tus neeg muag khoom uas nkag siab txog cov ntsiab lus no, tsis yog ib qho uas muag units. Chaw tsim tshuaj paus qhov chaw, zoo li Handan Zitai nyob rau hauv Yongnian, ib lub hub loj fastener, qhia tias lawv tau embedded nyob rau hauv lub lag luam cov khoom saw. Koj tuaj yeem nrhiav lawv cov ntaub ntawv ntawm https://www.zitaifasteners.com. Lawv qhov zoo dua yog qhov zoo ntawm qhov ntsuas thiab metallurgical sib xws rau cov qauv qib, uas yog lub hauv paus ntawm kev ntseeg tau. Tab sis lawv cov ntawv spec yog qhov pib, tsis yog qhov kawg.

Yog li, Cov Lus Teb Tiag yog dab tsi?

Lawv ruaj npaum li cas? Ib tug kom raug teev thiab ntsia Kev nthuav dav Bolt Hook system tuaj yeem kav lub neej ntawm lub tsev. Cov kab lus tseem ceeb yog qhia kom raug thiab ntsia. Tus nuv nws tus kheej feem ntau yog qhov muaj zog tshaj plaws. Qhov tsis zoo yog, nyob rau hauv kev txiav txim: lub substrate, compatibility thiab zoo ntawm expansion shield, installation kev qhuab qhia, thiab thaum kawg, ib puag ncig tiv thaiv ntawm hlau.

Kuv txoj cai ntawm tus ntiv tes xoo tam sim no yog ib txwm derate. Yog tias daim ntawv spec hais tias 10 hli nuv tuav 500 lbs hauv pob zeb, kuv npaj kuv daim ntawv thov rau 250-300 lbs max. Qhov no suav nrog qhov sib txawv ntawm qhov tsis paub - qhov tsis paub zoo ntawm cov pob zeb, kev teeb tsa me me, tsis muaj zog loads, thiab corrosion dhau sijhawm.

Thaum kawg, durability tsis yog ib yam khoom uas koj yuav tawm ntawm txee. Nws yog qhov tshwm sim uas koj tsim los ntawm kev xaiv kom raug, kev teeb tsa kom zoo, thiab kev tswj xyuas qhov tseeb. Tus nuv tsuas yog ib daim ntawm cov hlau zoo li tus. Nws lub neej ntev yog txiav txim siab los ntawm txhua yam koj ua ua ntej thiab tom qab koj xaub nws mus rau hauv phab ntsa.
