Uva ukunyathela kweempawu ezisi-7 ziphoswa macala onke, ngakumbi xa ujongene nemizobo yesakhiwo esivela kwimimandla ethile okanye koomatshini abathile abathumela ngaphandle. Ingqikelelo ekhawulezileyo ikholisa ukuba yinto esemgangathweni, engaphandle kweshelufu. Ngumgibe wokuqala lowo. Ngokwamava am, kunqabile ukuba kube lula ngolo hlobo. Ayilonani nje eliyinxalenye; lubalulo oluhlala ekudibaneni kokubalwa komthwalo, uyilo lwe-baseplate, kwaye, okona kubaluleke kakhulu, ukufunwa kwe-fastener. Ukuyifumana kakubi akuthethi ukulibaziseka; lithetha ulwakhiwo oluthotywa ukusuka phantsi ukuya phezulu.

Ukucazulula iNdawo eneempawu ezisi-7

Ke, sithetha ngantoni kanye kanye? Oonobumba abasi-7 babhekisa kwisixokelelwano sekhowudi ethile esetyenziselwa iibholithi ze-ankile okanye iziqhoboshi zesiseko, ichaza iiparamitha ezinjengodayamitha, ubude, uhlobo lwentambo, kwaye ngamanye amaxesha ibakala lemathiriyeli. Luphawu olujiniweyo. Ingxaki nantsi, le khowudi ayikho jikelele. Inkcazo eneempawu ezisi-7 ukusuka kwifemu yobunjineli enye isenokuthetha ukudipha okushushu kwegalvanized, ngelixa enye ithatha intsimbi yekhabhoni engenanto ngonyango olukwisiza. Ndichithe iiyure ndithelekisa ezi khowudi kunye neemfuno zobugcisa, kwaye ukungacaci kulapho iiprojekthi zincamathela khona.

Ndikhumbula iprojekthi yolwakhiwo lwenkxaso yokuthutha apho imizobo yayibiza into ethile Iinyawo ezi-7 ikhowudi. Iqela lokuthenga, elijolise kukongiwa kweendleko, lafumana into yokuqhobosha ehambelana nedayamitha yokwenyani nobude. Baphose ukuba ikhowudi ifuna amandla esivuno ayi-8.8, kwaye oko kwafikayo yayilibakala le-4.8. Umehluko? I-ductility ebalulekileyo xa ithelekiswa nendawo ebhityileyo yokusilela phantsi komthwalo oguqukayo. Siyibambe ngexesha lokujonga ukufakwa kwangaphambili, kodwa kubangele ukumiswa kweprojekthi yeeveki ezintathu. I-takeaway: ikhowudi yindawo yokuqala yencoko, kungekhona isiphelo sayo.

Kulapho umxholo wejografi ubalulekile. Ukuba usebenza kunye neziseko zokuvelisa kwiindawo ezifana neSithili saseYongnian eHandan, iHebei-eyaziwa njengeyona nxalenye inkulu yemveliso yaseTshayina-uyakwazi ukufikelela kumthamo omkhulu wokuvelisa. Inkampani emi apho, njenge-Handan Zitai Fastener Manufacturing Co., Ltd., isebenza ngokoqobo kumbindi we-ecosystem. Ukusondela kwabo kumakhonkco othutho amakhulu afana neBeijing-Guangzhou Railway kunye neNational Highway 107 ayiyondawo yokuthengisa nje; iguqulela kwimpumelelo yolungiselelo lwe-bulk, ii-odolo ze-fastener enzima. Kodwa nangaloo nzuzo, incoko yababini ecacileyo ingundoqo. Awunako ukuthumela nge-imeyile ikhowudi kwaye ulindele umdlalo ogqibeleleyo.

Ingxoxo ngeNgcaciso: Ngaphaya kweKhowudi

Oku kukhokelela kwinkqubo ebonakalayo. Xa ndifuna ukuguqulela a Iinyawo ezi-7 I-callout kwi-oda lokuthenga, inyathelo lokuqala liphepha lokuqhawula. Sidwelisa zonke iimpawu eziqikelelweyo: i-diameter yegama, i-pitch, ubude bomsonto, ubude be-shank ngokubanzi, uhlobo lwentloko (ukuba lukhona), ibakala lemathiriyeli (umzekelo, i-Q235B, 35, 45), iimpawu zomatshini, unyango lomphezulu (i-galvanizing, i-zinc plating, i-oxide emnyama), kunye nayo nayiphi na imigangatho esebenzayo (GB, DIN, ISO). Eli phepha liba yibhayibhile yobugcisa yeRFQ.

Nanku umngxunya oqhelekileyo: unyango lomphezulu lokukhusela umhlwa. Ikhowudi isenokungayicacisi, kodwa imeko-bume yofakelo iyayenza. Kwisiseko sangaphandle kwimozulu efumileyo, i-hot-dip galvanizing ayinakuxoxisana. Ndizibonile iibhetshi zifika zine-electroplated zinc coating kuba ibingumgangatho womthengisi waloo khowudi, ayifanelanga kwaphela isicelo. Ukungaphumeleli kubonakala njengamabala erusi phakathi konyaka kunye nokunciphisa umthwalo we-clamp ekuhambeni kwexesha. Ngoku, sihlala sihlomela amanqaku okusingqongileyo kwii-specs zethu.

Ukusebenza nabavelisi abakhethekileyo kulungelelanisa oku. Xa uzibandakanya neqela lokuthengisa lobuchwephesha kumvelisi-uthi, lowo uchaza amandla akhe njengeZitai Fasteners, egxininisa indawo ekuyo kwisiseko esikhulu semveliso-awuthethi nje nomsasazi. Ungaxoxa nge-metallurgy, inkqubo yokuthunga (iqengqiwe vs. Ukusika), kunye nolawulo lomgangatho wokunyamezela komgangatho. Ungabuza, Kule khowudi inabalinganiswa abasi-7 ethetha ukusetyenziswa kwindawo yenyikima, ungacebisa ubude bokuzibandakanya komsonto owahlukileyo okanye imathiriyeli yomgangatho ophezulu? Leyo yingxoxo ethintela ukungaphumeleli.

Ulungiselelo kunye neFactor enzima

Into ehlala ingahoywa yeziqhoboshi zesiseko bumzimba wabo opheleleyo. Ukuthunyelwa kwamakhulu aliqela Iinyawo ezi-7 iibholiti ze-ankile, nganye inokuba yi-1.2 yeemitha ubude kunye ne-36mm ububanzi, inzima kakhulu kwaye ayinzima. Ulungiselelo aluyonto icingelwayo; yinxalenye engundoqo yeendleko kunye novavanyo lomngcipheko. Apha kulapho indawo yomthengisi ibonisa ixabiso layo.

Umvelisi osekwe kwindawo efana neYongnian, enokufikelela ngokuthe ngqo kwi-Beijing-Shenzhen Expressway kunye ne-National Highway 107, unenzuzo eyakhelwe-ngaphakathi yokuhlanganiswa kwempahla yasekhaya kunye nokufikelela kwizibuko zokuthumela ngaphandle. Iyanciphisa ukuphatha, yehlisa umngcipheko womonakalo kuhambo (imisonto egobileyo iliphupha elibi ukulungisa kwindawo), kwaye inokucheba iintsuku ezibalulekileyo kwishedyuli. Ndithelekise iimeko apho ukukhangela indawo engaqhelekanga yongezwe ngaphezulu kwe-15% kwixabiso elibekiweyo kulungiselelo oluntsonkothileyo lwemilenze emininzi.

Ukupakishwa kubaluleke kakhulu. Ezi ayingomalungu amancinci. Kufuneka zikhreyithwe okanye zidityaniswe ngendlela ethintela ukonakala kwemisonto ngexesha lothutho lolwandle. Umenzi olungileyo uyakwazi oku kwaye uya kwakha ukupakishwa okuqinileyo, okupakishwayo njengenxalenye yenkonzo. Yinkcukacha encinci ethetha ngamava asebenzayo.

Inqaku leMba: I-Baseplate eLungisiweyo yeFiasco

Esona sifundo sam sifundisayo kwesi sihloko sivela kwiprojekthi ebandakanya iziseko zoomatshini abakhulu ezilungelelanisiweyo. Imizobo yayinomgangatho Iinyawo ezi-7 i-spec yeebholithi ze-ankile. Nangona kunjalo, i-baseplates yayinemingxuma emikhulu yokuvumela ukulungelelaniswa kokugqibela ngaphambi kokuba i-grouting. Ubude bebholiti obuqhelekileyo, ngokwekhowudi, babunganelanga ukunika ingxelo ngamandongomane okulinganisa kunye neewasha ezifunekayo ngaphantsi.

Asizange siyibambe de kwafakwa. Iibholithi bezimfutshane kakhulu. Isisombululo esivela kwiqela lentsimi sasiyi-weld extensions kwi-bolts-umsebenzi otshabalalisa ngokupheleleyo unyango olushushu kunye neempawu zemishini yentsimbi, ukudala indawo ebuthathaka ebalulekileyo. Kwafuneka sikhabe ibhetshi yonke. Ukulungiswa kwakuyi-odolo epheleleyo kunye nesiko, ubude obungalinganiyo, apho umenzi, kwi-credit yabo, wajika ngokukhawuleza ngenxa yokuba babenezixhobo eziluhlaza kunye nenkqubo yokubumba ngaphakathi kwendlu. Isifundo sasibuhlungu: inkcazo yeenyawo ayinakuphononongwa yodwa. Kufuneka ihlolwe ngokuchasene nendibano yangempela-ubukhulu be-baseplate, umaleko we-grout, inkqubo yokulinganisa, kunye neprojekthi efunekayo yentambo.

Ngoku, uluhlu lwethu lokukhangela lubandakanya ukubalwa kobude obugcweleyo bebholithi ebangela zonke ezi maleko. Ikhowudi yoonobumba abasi-7 isinika isiqalo sedayamitha kunye nebakala, kodwa singabanini bobude obucacileyo bokugqibela.

Iingcamango Zokuqukumbela: Imalunga neNkuthalo efunekayo

Ke, emva kwayo yonke le nto, uthini umbono kwi Iinyawo ezi-7? Yinto emfutshane eluncedo, kodwa intonga eyingozi. Imele ubuncinci besiseko solwazi. Ukuyiphatha njengenkcazo epheleleyo yokuthenga ngumngcipheko wengcali.

Ukuthembeka kuvela kwinkqubo oyisongileyo: ukonakaliswa kobugcisa, ukhetho lomthengisi olusekwe kwimveliso kunye nesakhono solungiselelo, kunye nokutshekishwa kokugqibela ngokuchasene nomzobo wendibano epheleleyo. Ngumahluko phakathi kokuthenga imveliso kunye nobunjineli njengecandelo.

Ekugqibeleni, iiprojekthi eziphumeleleyo zivelisa ezi zinto kumaqabane aqonda injongo yobunjineli emva kwekhowudi, hayi ikhowudi ngokwayo. Oko kufuna ukujonga ngaphaya kwekhathalogu kunye ne-Foundry, ivenkile yokuthunga, kunye nelebhu esemgangathweni. Kulapho ufumana unyawo lokwenyani lwesakhiwo sakho.
