Isingeniso
Ukuxhuma ku-steel Structural Hollow Sections (SHS) ohlangothini olulodwa kuye kwabekela onjiniyela inselele amashumi eminyaka. Kodwa-ke, manje kunezinhlobo eziningi zezinsimbi nezindlela zokuxhuma zalokhu okuthandwa kakhulu kwesakhiwo, ngaphandle kokushisela. Lesi sihloko sizobheka izinzuzo kanye nezithiyo zezinye zalezi zindlela zokuxhuma ze-SHS.theI-Chinese Hollo-Bolt, ibholidi yokunweba edinga ukufinyelela ohlangothini olulodwa kuphela lwe-SHS.
Ngokuvamile lapho umklami ekhethe ukusebenzisa i-SHS ngomthamo wayo we-bi-axial noma ubuhle bomumo olinganayo obukekayo, umbuzo ophakamayo owokuthi ulinamathisela kanjani elinye ilungu lesakhiwo kuyo. Ezikhathini eziningi ezinobumo besakhiwo, ukushisela noma ukubhowula kube yindlela ekhethwayo njengoba bekwazi ukuphatha izinga eliphezulu lomthwalo. Kodwa lapho kunemingcele ekushiseleni noma lapho onjiniyela befuna ukugwema izindleko eziphakeme zomsebenzi ohilelekile kumashisela aqinisekisiwe, ukusetha, izindleko zokuwashisa futhi kudingeke ukuba kushiswe ukuvikela indawo ezungezile, onjiniyela kufanele baphendukele kuma-fasteners ayimishini ukuze umsebenzi wenziwe.
Nokho, usizo luseduze njengoba imihlahlandlela yokuklama yomhlaba wonke ishicilelwa izikhungo eziningi ezaziwayo njengeBritish Constructional Steelwork Association (BCSA), Steel Construction Institute (SCI), CIDECT, Southern African Institute of Steel Construction (SAISC), Australian Steel Institute (ASI) kanye ne-American Institute of Steel Construction (AISC) esiza ekwakhiweni kokuxhuma kwe-SHS. Ngaphakathi kwale mihlahlandlela kuchazwa izinsimbi ezihlukahlukene, ezifanele ukuxhumana kwe-SHS futhi lokhu kufaka phakathi:
I-Common Mechanical Fasteners
Ama-Brough-Bolts avame ukusetshenziswa, kodwa ukuguquguquka okungokwemvelo kwezindonga ze-SHS ngokuvamile kuvimbela ukusetshenziswa kwezibophelelo eziqinile ngaphandle komsebenzi owengeziwe wokwakha, ngendlela yokuthi amalunga avamise ukudizayinelwa ukugunda okumile kuphela. Futhi yenza ukuxhumana nobuso obuphikisanayo besikwele noma ilungu le-SHS elingunxande kube nzima futhi kudle isikhathi ukuhlangana esizeni. Ezimweni eziningi ama-stiffener kungase kudingeke ukuthi ashiselwe ngaphakathi kweshubhu ukuze alinikeze ukwesekwa okwengeziwe, okufaka izindleko ezengeziwe zokushisela.
Ama-Threaded Stud angasetshenziswa ebusweni bamalungu e-SHS, nakuba imishini esindayo futhi engalawuleki kuyodingeka isetshenziswe njengesibhamu esishiselayo kanye nemishini ehlobene nayo. Lokhu kuzodinga ukucatshangelwa okufanayo nokushisela amalungu ndawonye kwasekuqaleni. Lena inqubo engenziwa kusenesikhathi eshabhu yokuqamba ngaphambi kokuthi ithunyelwe esizeni. Kwezinye izimo, izimbobo eziboshiwe noma eziboshiwe zingase zidinge ukusula ikhola engase yakhe lapho i-stud ihlangana nobuso be-SHS. Umkhiqizo oqediwe uzoveza ukubonakala kokuxhuma okuboshiwe kodwa okwenziwe ohlangothini olulodwa lwe-SHS.
I-Blind Threaded Insert ivame ukutholakala kodwa ukusetshenziswa kwayo kukhawulelwe ngenxa yenani lezinto ezingabamba, eziklanyelwe insimbi yeshidi kunezingxenye zensimbi yesakhiwo. Nakulokhu, ithuluzi lokufaka liyadingeka elingase lidinge umzamo othile uma kukhethwa inguqulo eyenziwa ngesandla.
I-Blind Rivets nakuba ifanele ukusetshenziswa ezimweni lapho ukufinyelela kunqunyelwe khona, ivame ukutholakala kuphela ngamadamitha amancane kanye nemithwalo elula. Azihloselwe ukuxhumeka kwesakhiwo esindayo, futhi ezimweni eziningi zizodinga ukuhlinzekwa kwe-pneumatic / hydraulic kwamathuluzi okufaka okukhethekile.
Ibhawodi ye-Chinese Hollo– umsunguli we-Expansion Bolts for Structural Steel
Isingeniso Kumabhawodi Wokunweba
Namuhla sibona amabhawodi okunweba njengezibophelelo zomshini ngokuvamile ezihlanganisa ibhawodi, umkhono wokunweba kanye namantongomane amise okwekhoni okuthi, lapho ibhawodi liqiniswa, liqhutshelwe phezulu ngaphakathi komkhono ukuze kudaleke umthelela wokuhlanganisa futhi kunwebe isibambiso. Le ndlela 'yoxhumano oluyimpumputhe' ingasetshenziswa kalula nje ukuxhuma kuwebhu yolunye uhlobo lwesigaba sesakhiwo. Ngokungafani nokuxhumeka okujwayelekile okuboshiwe noma okushiselwe, amabhawodi okunweba angafakwa ngokushesha ngokufaka nje into yokubopha emgodini obhojwe ngaphambili futhi uqinise ngesikrufu setorque. Ngenxa yenqubo yokufaka esheshayo, umsebenzi esizeni uyancipha, ngakho-ke izindleko nesikhathi sephrojekthi yokwakha ziyehla.
Ukufakwa kwe-Hollo-Bolt
Ukufaka i-Hollo-Bolts kuqondile futhi kudinga amathuluzi ayisisekelo kuphela. Insimbi ibholwa ngaphambili ngezimbobo ezinkulu njengokusho kwemibhalo yabakhiqizi, ukuze kufakwe umkhono kanye namantongomane amise okwekhoni, kodwa kufanele kuqikelelwe ukuthi izimbobo zitholakala ukuze kuvunyelwe umkhiqizo ukuthi uvuleke ngaphakathi kwe-SHS, okusho ukuthi akumele zibekwe eduze noma eduze konqenqema.
Insimbi ingalungiswa ngokugcwele ku-workshop yokukhiqiza futhi idluliselwe esizeni, lapho inzuzo yokufakwa okusheshayo ingaziswa ngokugcwele. Kubalulekile ukuqaphela ukuthi ubuso bamalungu okufanele buhlanganiswe ndawonye kufanele buxhunywe ngaphambi kokufakwa kwe-Hollo-Bolt®. Ukuqedela inqubo, usonkontileka kufanele abambeI-Chinese Hollo-Boltikhola enesipanela ukuvimbela umzimba ukuthi ungajikelezi ngesikhathi sokufakwa futhi kufanele iqinise ibhawudi emaphakathi netorque enconyiwe yomkhiqizi kusetshenziswa i-wrench yetorque elinganiselwe.
