Ama-bolts ayimikhiqizo ye-hardware evamile kakhulu ekuphileni kwethu kwansuku zonke futhi adlala indima ebaluleke kakhulu ekuphileni kwethu.Kodwa-ke, abantu abaningi abakuqondi ukucaciswa nosayizi wamabhawudi.Namuhla, sizokunikeza isingeniso sesayensi sokumelelwa okulungile kwamabhawudo okuhanjwa ngayo, ngethemba lokukusiza.
1. Ukukhetha impahla yebhawudi yesisekelo
Ngokuvamile, izinto zebhawodi lehange kufanele zibe ngu-Q235.Uma amandla enganele, ibholidi yehange engu-16Mn ingakhethwa ngokubala.Ngokuvamile, kusetshenziswa ibhawudi le-ancho ye-Q235, futhi ibhawodi liyaqina futhi liyamelana nokuphuma.
Eqinisweni, ama-anchor bolts ngeke aphinde adlale indima enkulu esakhiweni sensimbi esifakiwe.Ingxenye kuphela yamandla okugunda ekhona, ngoba umsebenzi oyinhloko uwukusekela ngemva kokufakwa, ngakho ukucaciswa kufanele kubhekiswe lapho kukhethwa amabhawodi okusetshenzwa kulengwa.Eqinisweni, ngokuvamile sisebenzisa i-Q235B noma i-Q235A kuphela, futhi ngokuvamile asisebenzisi hook ye-Q345, enobude obungekho ngaphansi kuka-150mm.
Ama-anchor bolts: angahlukaniswa abe ama-anchor bolts kanye nama-bolts wesakhiwo.Ukukhethwa kwama-bolts we-anchor kufanele kucatshangelwe ngombono wokucindezeleka, okungukuthi, amandla okugunda, ama-tensile kanye nama-torsional aphethwe ama-bolts asekelayo.Ngesikhathi esifanayo, njengoba ama-anchor bolts, kufanele ikakhulukazi athwale amandla okugunda.Ngakho-ke, i-Q235 (futhi kucatshangelwa izinga lokushisa kwemvelo ukuze kugwenywe "i-blue brittleness") kufanele kukhethwe ezimweni eziningi.Lapho izakhiwo, izakhiwo noma okokusebenza okugxilwe amabhawodi okusetshenzwa kulengwa asendaweni kunokudonseka okusobala noma ukugobhoza kumabhawodi okusetshenzwa kulengwa, eyokuqala kufanele ibalwe futhi ikhethwe ngobubanzi noma ikhethe ngokuqondile i-16Mn enamandla amakhulu okudonsa, futhi lokhu kokugcina kufanele kuxazululwe ngokukhulisa inani lamabhawodi okusetshenzwa kulengwa.Phela izinto zokwakha ziyabiza manje.
Kungcono ukusebenzisa i-Q235A.I-Q235B ibiza kakhulu kune-Q235A.Amabhawodi okusetshenzwa kulengwa kuwo awadingi ukushiselwa, ngakho-ke KULUNGILE ukusebenzisa iBanga A.
2. Ukucubungula ubuchwepheshe bezinto ezibonakalayo zebhawodi
Inqubo yokucubungula yebholithi yehange: vula intambo kuqala, bese ugoba ihhuku, bese uwela i-Q235 enobude obufanayo obungu-150mm eduze kwehhuku.Ngaphezu kwalokho, kufanele kuqashelwe ukuthi i-A3 iyinombolo yomkhiqizo endala, futhi manje ihambisana nensimbi ye-Q235A.A3, okuyigama elidlule.Nakuba isasetshenziswa, ilinganiselwe olimini olukhulunywayo.Kungcono ukungayisebenzisi emibhalweni ebhaliwe.Kuyinsimbi ye-Class A.Umkhiqizi walolu hlobo lwensimbi uqinisekisa kuphela ukusebenza komshini kodwa hhayi ukwakheka kwamakhemikhali lapho ephuma efekthri, Ngakho-ke, izingxenye zokungcola ezifana no-S no-P zingase zibe ngaphezulu kancane, futhi okuqukethwe kwekhabhoni cishe ku-0.2%, cishe kulingana Insimbi engu-20, elingana ne-Q235 ezingeni elisha.I-A3 ne-A3F amagama angaphambili e-Q235-A, Q235-A.Insimbi ye-F A3 kanye ne-Q235, i-Q345 amamaki ensimbi yesakhiwo se-carbon.I-A3 yizinga lensimbi elisezingeni elidala, kodwa izinga lamanje (GB221-79) alinalo ibanga elinjalo.
Ezingeni lamanje, i-A3 ifakiwe ku-Q235.I-Q235 imele ukuthi amandla okukhiqiza ale nsimbi angama-235MPa.Ngokufanayo, i-345 ku-Q345 ingahlukaniswa ngezigaba eziningana, okuhlanganisa: A - ukuqinisekisa izakhiwo zemishini, B - ukuqinisekisa izakhiwo zemishini kanye nezindawo zokugoba ezibandayo, C - ukuqinisekisa ukwakheka kwamakhemikhali ... Esilinganisweni esidala, incazelo ye-A , B, C ayihlukile kakhulu kulokho okusesilinganisweni esisha (ngilinganisela ukuthi kunjalo), futhi 1, 2, 3...... Zisetshenziselwa ukukhombisa amandla.U-1 umele amandla okukhiqiza angu-195MPa, u-2 umele amandla okukhiqiza angu-215MPa, kanti u-3 umele amandla okukhiqiza angu-235MPa.Ngakho-ke i-A3 ilingana ne-Q235A kumkhiqizo omusha.Phela i-A3 ike yasetshenziswa ngaphambilini, abantu abaningi bajwayele ukuyisebenzisa, njengoba abanye bejwayele ukusebenzisa amayunithi e-"jin, liang".I-Q235 iyinsimbi yesakhiwo sekhabhoni.Uma kuqhathaniswa namabanga amadala ajwayelekile e-GB700-79, i-A3 ne-C3 Q345 ayinsimbi yesakhiwo se-alloy ephansi.Uma kuqhathaniswa nezinga elidala le-1591-88 amamaki, ziningi kakhulu izakhiwo kanye nezicelo ze-12MnV, 16Mn 16MnRE, 18Nb kanye ne-14MnNb Q345 - i-shaft ne-weldment inezakhiwo ezinhle ezibanzi zemishini, izakhiwo eziphansi zokushisa, ipulasitiki enhle kanye nokushisela.Asetshenziswa njengezakhiwo ezithwala imithwalo enamandla, izingxenye zemishini, izakhiwo zokwakha, kanye nezakhiwo zensimbi ezijwayelekile zemikhumbi yomfutho ophakathi nendawo, amathangi kawoyela, izimoto, ama-cranes, imishini yezimayini, izitshalo zamandla, amabhuloho, njll., futhi angasetshenziswa ezindaweni ezishisayo. izimo zokugingqa noma ezijwayelekile.Zingasetshenziselwa izakhiwo ezihlukahlukene ezindaweni ezibandayo ezingezansi - 40 ℃.
