Intshayelelo
Ukuqhagamshela kwintsimbi yeStructural Hollow Sections (SHS) ukusuka kwicala elinye kuye kwacela umngeni kwiinjineli amashumi eminyaka. Nangona kunjalo, ngoku kukho iintlobo ezininzi zeefasteners kunye neendlela zoqhagamshelo zolu lwakhiwo luya luthandwa, ngaphandle kwe-welding. Eli nqaku liza kujonga iingenelo kunye nezithintelo kwezinye zezi ndlela zoqhagamshelwano lwe-SHS.theIsiTshayina Hollo-Bolt, ibholithi yokwandisa efuna ukufikelela kuphela kwicala elinye le-SHS.
Rhoqo xa umyili ekhethe ukusebenzisa i-SHS kumthamo wayo we-bi-axial okanye ubuhle bembonakalo enomtsalane yeemilo ezilinganayo, umbuzo ovelayo ngowokuba uncamathisela njani elinye ilungu lolwakhiwo kuyo. Amaxesha amaninzi ngeemilo zesakhiwo, i-welding okanye i-bolting ibe yindlela ekhethwayo njengoko inokusingatha iqondo eliphezulu lomthwalo. Kodwa xa kukho imiqathango yokuwelda okanye apho iinjineli zifuna ukuphepha iindleko eziphakamileyo zomsebenzi obandakanyekileyo kwiintsimbi zokuwelda ezivunyiweyo, ukuseta, iintlawulo zokuqhekeka kunye nokukhusela umlilo kwindawo engqongileyo, iinjineli kufuneka zibhenele kwiziqhoboshi zoomatshini ukuze umsebenzi wenziwe.
Nangona kunjalo, uncedo lusemnyango njengoko izikhokelo zoyilo lwehlabathi zipapashwa linani lamaziko adumileyo afana neBritish Constructional Steelwork Association (BCSA), iSteel Construction Institute (SCI), CIDECT, Southern African Institute of Steel Construction (SAISC), Australian Steel Institute (ASI) kunye neAmerican Institute of Steel Construction (AISC) encedisa kuyilo loqhagamshelo lwe-SHS. Ngaphakathi kwezi zikhokelo iintlobo ngeentlobo zeziqhoboshi zoomatshini, ezifanelekileyo kuqhagamshelo lwe-SHS, zichaziwe kwaye ezi ziquka:
IiFasteners zoomatshini eziqhelekileyo
IiBolts zisetyenziswa ngokuqhelekileyo, kodwa ukuguquguquka okungokwemvelo kweendonga ze-SHS kuthintela ukusetyenziswa kweziqhoboshi ezigxininisiweyo zangaphambili ngaphandle komsebenzi owongezelelweyo wobugcisa, onje ukuba amalungu athanda ukuyilwa ukucheba okumileyo kuphela. Yenza kwakhona ukudibanisa ubuso obuchasayo besikwere okanye ilungu le-SHS elixande nzima kwaye lidla ixesha lokuhlanganisana kwisiza. Kwiimeko ezininzi ii-stiffeners zinokudityaniswa ngaphakathi kwityhubhu ukuze zinike inkxaso eyongezelelweyo, nto leyo ebangela iindleko ezongezelelweyo ze-welding.
Ii-Threaded Studs zingasetyenziswa ebusweni bamalungu e-SHS, nangona izixhobo ezinzima nezingalawulekiyo kuya kufuneka zisetyenziswe ngohlobo lompu we-weld kunye nezixhobo ezinxulumeneyo. Oku kuya kufuna ukuqwalaselwa okufanayo njengoko udibanisa amalungu ndawonye kwasekuqaleni. Le yinkqubo enokwenziwa ngaphambi kwexesha kwiworkshop yokwenziwa phambi kokuba ithunyelwe kwindawo. Kwezinye iimeko, imingxuma ekhutshiweyo okanye eboshiweyo inokuba yimfuneko ukususa ikhola enokuthi yenze apho i-stud idibana nobuso be-SHS. Imveliso egqityiweyo iya kuvelisa imbonakalo yoqhagamshelo lwebhoti kodwa yenziwe kwicala elinye kuphela le-SHS.
Ii-Blind Threaded Inserts zifumaneka ngokubanzi kodwa ukusetyenziswa kwazo kulinganiselwe ngenxa yobuninzi bezinto ezinokubamba, ekuqaleni ziyilelwe i-sheet metal kunamacandelo entsimbi. Kwakhona, isixhobo sokufakela siyafuneka esinokufuna inzame ethile ukuba kukhethwe uguqulelo olusetyenziswa ngesandla.
I-Blind Rivets nangona ifanelekile ukuba isetyenziswe kwiimeko apho ukufikelela kunqongophala, zivame ukufumaneka kuphela kwiidamitha ezincinci kunye nemithwalo elula. Azenzelwanga uqhagamshelo lwesakhiwo esinzima, kwaye kwiimeko ezininzi ziya kufuna unikezelo lwe-pneumatic / hydraulic kwisixhobo sofakelo esikhethekileyo.
Ibholithi yaseTshayina yeHollo– uvulindlela woKwandiswa kweeBolts zeStructural Steel
Intshayelelo kwiiBolts zoKwandiswa
Namhlanje siyaziqonda iibholithi zokwandisa njengezibophelelo zoomatshini ezibandakanya ibholithi, umkhono wokwandisa kunye nenati emile okwekhowuni ethi, xa ibholithi iqinisiwe, iqhutyelwe phezulu ngaphakathi komkhono ukwenza isiphumo sokutshata kunye nokwandisa isibophelelo. Obu buchwephesha 'bonxibelelwano oluyimfama' bunokusetyenziswa ngokulula ukudibanisa kwiwebhu yolunye uhlobo lwecandelo lolwakhiwo. Ngokungafaniyo noqhagamshelo oluqhelekileyo okanye oludityanisiweyo oludityanisiweyo, iibholiti zokwandisa zinokufakelwa ngokukhawuleza ngokufaka i-fastener kumngxuma owenziwe ngaphambili kwaye uqiniswe nge-wrench torque. Ngenxa yenkqubo yofakelo olukhawulezayo, umsebenzi kwisiza uyancitshiswa, kwaye ke ngoko iindleko kunye nexesha elibekiweyo leprojekthi yokwakha ziyancipha.
Ukufakelwa kweHollo-Bolt
Ukufakela i-Hollo-Bolts ngokuthe ngqo kwaye kufuna izixhobo ezisisiseko kuphela. Intsimbi igrunjwe ngaphambili kunye nemingxuma emikhulu ngokoncwadi lwabavelisi, ukulungiselela i-sleeve kunye ne-cone-shaped nut, kodwa kufuneka kuthathelwe ingqalelo ukuqinisekisa ukuba imingxuma ibekwe ukuvumela ukuba imveliso ivuleke ngaphakathi kwe-SHS, oku kuthetha ukuba ayinakubekwa ngokusondeleyo kunye okanye kufuphi nomphetho.
Intsimbi inokulungiswa ngokupheleleyo kwi-workshop yokwenziwa kwaye idluliselwe kwisiza, apho inzuzo yokufakela ngokukhawuleza inokubonga ngokupheleleyo. Kubalulekile ukuqaphela ukuba ubuso bamalungu adityaniswe kunye kufuneka zidityaniswe phambi kokuba i-Hollo-Bolt® ifakwe. Ukugqiba inkqubo, unokontraka kufuneka abambeIsiTshayina Hollo-Boltikhola enesipanela ukuthintela ukujikeleza komzimba ngexesha lofakelo kwaye kufuneka uqinise ibholithi esembindini kwitorque ecetyiswa ngumenzi usebenzisa isitshixo setorque esilungisiweyo.
