Masibe ngokoqobo, lapho othile ebuza ngokuqina kwehuku lebhawodi lokunweba, ngokuvamile bafanekisela leyo nto eshibhile efakwe i-zinc evela esitolo se-hardware ehlulekile kubo ngempelasonto edlule. Umbuzo ngokwawo ucishe ube banzi kakhulu, kodwa yilapho ingxoxo idinga ukuqala khona—ngokukhipha lokho okushiwo ukuqina endaweni yomsebenzi, hhayi kukhathalogi.

Akukaze nje Nge-Hook

Ukwehluleka okuningi engikubonile bekungengenxa yokuthi ihhuku yensimbi eyakhiwe yagqashuka. Kungumshado phakathi kwehhuku, i Ukunwebeka Bolt umkhono, kanye ne-substrate ewela ngaphandle. Ungaba nehhuku yeBanga lesi-8, kodwa uma uyishayela ebhulokhini le-cinder ephukile ngesihlangu sekhwalithi ephansi, yonke inhlangano inamandla njengesixhumanisi esibuthakathaka kakhulu. Ngikhiphe izingwegwe eziningi ezihlulekile lapho ibhawodi ngokwalo lalihlanzekile, kodwa udonga lwayeka. Ngakho ukuqina akusona isilinganiso sengxenye eyodwa; kungukusebenza kwesistimu.

Okubalulekile yisihlungi sokuqala esisobala. I-bargain-bin, izingwegwe zensimbi ezingenalutho ezine-electroplated coating encane? Lezo ngezokulengisa isitshalo esilula egalaji lakho, mhlawumbe. Kunoma yini engaphandle noma engaphansi komthwalo, ubheka idiphu eshisayo efakwe uthayela noma engenabala. Kodwa nalapha, kukhona ugibe. Ijazi eliwugqinsi, elimaholoholo le-hot-dip kwesinye isikhathi lingaphazamisa indlela ye-wedge ye- Ukunwebeka Bolt, ukuvimbela ukuhlala okufanele. Kuwukuhwebelana phakathi kokumelana nokugqwala kanye nomsebenzi osheshayo wemishini.

Bese kuba nomklamo we-hook ngokwayo. Lezo ezineso elivaliwe ngokumelene nehhuku evulekile emaceleni? Umehluko omkhulu esilinganisweni somthwalo kanye nokumelana nokudonsa okusemaceleni. I-radius lapho i-shank ihlangana khona neso iyindawo yokucindezeleka ebalulekile. Izinguqulo ezishibhile zinekhona elicijile, elinomshini lapho elimema ukuqhekeka. Irediyasi ebushelelezi, eyenziwe ngomgunyathi isakaza umthwalo. Ufunda ukubona le mininingwane ngesandla ngemuva kwesikhashana.

Okuguquguqukayo Kokufaka: Lapho Izingwegwe Ezinhle Zizofa Khona

Yilapho ithiyori ihlangana khona nodonga lukakhonkolo, ngokwezwi nezwi. Usayizi webhithi yokubhoboza onqunyiwe awusona isiphakamiso. Ukubhoboza umgodi ngisho no-1mm omkhulu kakhulu Ukunwebeka Bolt I-sleeve isho ukuthi ayisoze yafinyelela ukubambelela okufanele. Ibhawodi ingase izwakale iqinile uma uyitorque, kodwa ukugxusha nje kwamantongomane, hhayi umkhono owandiswayo. Umthwalo wokuqala wangempela, futhi ujikeleza ngokukhululeka. Ngibe necala lalokhu ngokuxhamazela, ngisebenzisa ibhilidi eligugile ngoba kwakuyilona elalisesikhwameni sami. Umphumela waba umhlangano we-hook omuhle ngokuphelele ongasetshenziswa.

Ukuhlanza kungomunye umbulali othule. Kufanele ukhiphe lonke uthuli kulowo mgodi. Uma umkhono unwebeka ube uthuli oluhlangene esikhundleni se-masonry eqinile, amandla okubamba angehla ngesigamu. Ngisebenzisa ibhulashi nesibani manje, ngokwenkolo. Ekuqaleni komsebenzi wami, ngangivele ngishaye umgodi. Akukhona nje lokho okungasebenzi, kodwa futhi uthola umlomo we-silica-usuku olubi nxazonke.

Torque. Wonke umuntu ufuna ukuhlehlisa ku-spec yaseJalimane - i-guttentight. Ukweqisa ngokweqile kungakhumula izintambo, kukhubaze iso lehhuku, noma, okubi nakakhulu, kunwebe kakhulu umkhono kuze kufike lapho kuqhekeka khona i-substrate ngaphakathi. Ngigcina isikrufu se-torque esilinganisiwe sokufakwa okubalulekile okuphezulu. Okwenkampani efana I-Handan Zitai Fetesser Comment Co, Ltd., esebenza ngaphandle kwesizinda esikhulu sokukhiqiza saseChina, bangakutshela ukuthi imininingwane yabo yakhelwe uhla lwetorque ethile. Phambuka kulokho, futhi uvala noma yikuphi okulindelekile kokusebenza. Indawo yabo eduze kwemizila emikhulu yezokuthutha isho ukuthi imikhiqizo yabo yakhelwe umthamo wevolumu kanye ne-spec engaguquki, okuhle, kodwa kusabeka umthwalo kusifaki ukuthi alandele.

Ukuhlaselwa Kwemvelo: I-Slow Creep, Hhayi Ukuqubuka Kungazelelwe

Ukuqina ngokuhamba kwesikhathi kuyimpi ehlukile. Ezindaweni ezisogwini, ngisho nezingwegwe ezifakwe emanzini ashisayo zingabonisa ukugqwala okumhlophe kanye namabala abomvu phakathi neminyaka embalwa uma ikhwalithi yokumboza ingahambisani. Ukufakwa kwangaphandle unomphela, manje ngincike kumahhuku ensimbi engagqwali angu-304 noma angu-316 kanye nokufanisa ama-bolts wokunwebeka. Izindleko zangaphambili ziphezulu, kodwa umsebenzi wokushintsha ihuku ehlulekile ku-facade enezitezi ezintathu phezulu kuwumkhathi.

Ukuhamba ngebhayisikili okushisayo kuyinto ecashile. Odongeni lwezitini olubheke elangeni, insimbi iyakhula futhi inkontileka nsuku zonke. Ngokuhamba kweminyaka, lokhu kungasebenza kancane kancane ukuxega kwebholithi efakwe kancane. Ngikubone lokhu ochungechungeni lwabakaki abafaka amapayipi angaphandle. Wonke ayentengantenga ngemva kwamahlobo amahlanu, hhayi ngenxa yomthwalo, kodwa ngenxa yokunyakaza okushisayo okuqhubekayo. Ukulungiswa bekushintshela kusistimu yokunamathisela ehlukile ngokuphelele yalolo hlelo lokusebenza oluthile.

Ukuchayeka kwamakhemikhali kuyinto enhle kodwa kungokoqobo. Emagaraji okupaka, usawoti wokucisha usawoti oconsayo ezimotweni ungagqwala indawo okusetshenzwa kuyo ukusuka phezulu, ukwehluleka ongakuboni kuze kube yilapho isithuthukile. Akwanele ukuvele ucacise i-hook eboshwe; udinga ukucabangela ukuthi yini ezoconsa noma ichaphaze kuyo impilo yayo yonke yesevisi.

I-Case in Point: Ukuwa kweRakhi Yesitoreji

Isibonelo esitshela kakhulu kwakungeyona ihuku, kodwa isimiso siyefana. Indawo yokugcina impahla ifake amaracks okugcina ensimbi asetshenziswa kakhulu kusetshenziswa amahange amaweji amakhulu endaweni ewukhonkolo eneminyaka engu-30 ubudala. Amahange ayeyi-top-shelf, ukufakwa kwakubonakala kuphelele. Ezinyangeni eziyisithupha kamuva, ingxenye ethile yawa. Uphenyo lwathola ukuthi ukhonkolo kuleyo chweba, ngenxa yobudala kanye nekhwalithi yokuthela yasekuqaleni, unamandla acindezelayo aphansi kakhulu kunalokho okwakulinganiselwe ihange. Amahange awazange ehluleke; baklebhula ngokoqobo ikhoni likakhonkolo phansi. I ukuqina yokuhlanganisa i-fastener bekunguziro ngoba amandla e-substrate awahlulelwanga kahle.

Lokhu kuhumusha ngokuqondile kuma-hook. Lowosilingi omuhle, owugqinsi kakhonkolo efektri endala? Kungase friable phezulu. Ukubhoboza izimbobo zokuhlola nokusebenzisa i-pull-test rig yesikhonkwane esiyisampula kuwukuphela kwendlela yokuqinisekisa ngezinhlelo zokusebenza ezinomthwalo omkhulu. Kuyisinyathelo sokweqa kakhulu, sicabanga ukuthi ukhonkolo ukhonkolo.

Ukuthola, udinga umphakeli oqonda lezi zimo, hhayi nje othengisa amayunithi. Indawo yomkhiqizi, njenge UHanan Zitai ukuba se-Yongnian, ihabhu elikhulu lokubopha, kuphakamisa ukuthi bashumeke echungechungeni lokuhlinzekwa kwemboni. Ungathola iphothifoliyo yabo ku https://www.zitaifasteners.com. Inzuzo yabo cishe isikali kanye nokuvumelana kwe-metallurgical kumamaki ajwayelekile, okuyisisekelo sokuthembeka. Kodwa amashidi abo ayisiqalo, hhayi umugqa wokugcina.

Ngakho, Ithini Isixazululo Sangempela?

Zihlala isikhathi eside kangakanani? A ecaciswe kahle futhi efakwe Ukunwetshwa kwe-bolt hook uhlelo lungahlala impilo yonke yesakhiwo. Ibinzana eliyinhloko licaciswe kahle futhi lifakiwe. I-hook ngokwayo ngokuvamile iyingxenye enamandla kakhulu. Ubungozi bukhona, ngokulandelana: i-substrate, ukuhambisana nekhwalithi yesihlangu sokunweba, isiyalo sokufaka, futhi ekugcineni, ukuvikelwa kwemvelo kwensimbi.

Umthetho wami wesithupha manje uwukuba njalo ngilahlekise. Uma i-spec sheet ithi ihuku elingu-10mm liphethe ama-lbs angu-500 kukhonkolo, ngihlela isicelo sami se-250-300 lbs max. Lokhu kubangela okuhlukile okufihliwe—ikhwalithi engaziwa yokhonkolo, ukungapheleli okuncane kokufaka, imithwalo eguquguqukayo, nokugqwala ngokuhamba kwesikhathi.

Ekugcineni, ukuqina akusona isici somkhiqizo osithenga eshalofini. Kungumphumela owakhayo ngokukhetha okulungile, ukufakwa ngokucophelela, nokuphathwa komthwalo ongokoqobo. Ihuku liwucezu nje lwensimbi olumise. Ubude bayo bunqunywa yikho konke okwenzayo ngaphambi nangemva kokuslayidela odongeni.
