Bolt nibicuruzwa bikoreshwa cyane mubuzima bwacu bwa buri munsi kandi bigira uruhare runini mubuzima bwacu.Nyamara, abantu benshi ntibumva ibisobanuro nubunini bwa bolts.Uyu munsi, tuzaguha intangiriro yubumenyi muburyo bwiza bwo kwerekana ibyuma bya ankor, twizeye kugufasha.
1. Guhitamo ibikoresho bya fondasiyo
Muri rusange, ibikoresho bya ankor bigomba kuba Q235.Niba imbaraga zidahagije, 16Mn anchor bolt irashobora gutoranywa binyuze mukubara.Mubisanzwe, Q235 ya anchor ikoreshwa, kandi bolt irakomeye kandi ikurura.
Nkukuri, ibyuma bya ankeri ntibizongera kugira uruhare runini muburyo bwubatswe.Gusa igice cyogukoresha imbaraga zirahari, kuberako imikorere nyamukuru nugushyigikira nyuma yo kwishyiriraho, ibisobanuro rero bigomba koherezwa mugihe uhitamo inanga.Mubyukuri, muri rusange dukoresha Q235B cyangwa Q235A gusa, kandi mubisanzwe ntabwo dukoresha icyuma cya Q345, gifite uburebure buri munsi ya 150mm
Bolt ya Anchor: irashobora kugabanwa mubikoresho bya ankor bits hamwe na ankor yubatswe.Guhitamo ibyuma bya ankor bigomba gusuzumwa duhereye kubitekerezo, ni ukuvuga inkweto, imbaraga hamwe na torsional imbaraga zitwarwa na bolts zifatika.Igihe kimwe, nka ankeri ihindagurika, bagomba kwihanganira imbaraga zogosha.Kubwibyo, Q235 (nanone urebye ubushyuhe bwibidukikije kugirango wirinde "ubururu bwubururu") bigomba gutoranywa mubihe byinshi.Iyo inyubako, inyubako cyangwa ibikoresho byashyizweho na bits ya ankeri byaho bifite impagarara zigaragara cyangwa torsion kumurongo wa ankeri, iyambere igomba kubarwa no gutoranywa na diameter cyangwa guhitamo 16Mn ifite imbaraga zingana, kandi ibyanyuma bigomba gukemurwa no kongera Umubare wa Anchor Bolts.Nyuma ya byose, ibikoresho bihenze ubu.
Nibyiza gukoresha Q235A.Q235B ihenze kuruta Q235A.Bolt ya ankeri ntabwo ikeneye gusudwa, nibyiza rero gukoresha Grade A.
2. Gutunganya tekinoroji yibikoresho fatizo
Gutunganya inzira ya anchor bolt: hindura umugozi mbere, hanyuma uhetamye, hanyuma wambukane Q235 hamwe nuburebure bwibikoresho bingana na 150mm hafi yicyuma.Mubyongeyeho, twakagombye kumenya ko A3 numero ishaje, none ihuye na Q235A.A3 ibyuma, nizina ryashize.Nubwo iracyakoreshwa, igarukira ku mvugo ivugwa.Nibyiza kutayikoresha mubyangombwa.Ni Icyiciro A.Uwakoze ubu bwoko bwibyuma yemeza gusa imikorere yubukanishi ariko ntabwo arimiterere yimiti mugihe avuye muruganda, Kubwibyo, ibice byanduye nka S na P bishobora kuba bike, kandi ibirimo karubone bigera kuri 0.2%, hafi bihwanye na No 20 ibyuma, bihwanye na Q235 murwego rushya.A3 na A3F nizina ryambere rya Q235-A, Q235-A.F A3 ibyuma na Q235, Q345 ni amanota yicyuma cyubaka.A3 nicyiciro cyicyuma mubisanzwe bishaje, ariko igipimo kigezweho (GB221-79) nticyiciro nkicyo.
Mubisanzwe bigezweho, A3 iri muri Q235.Q235 yerekana ko imbaraga zumusaruro wibyuma ari 235MPa.Mu buryo nk'ubwo, 345 muri Q345 irashobora kugabanywamo ibyiciro byinshi, harimo: A - kwemeza imiterere yubukanishi, B - kwemeza imiterere yubukanishi hamwe nubukonje bukonje, C - kwemeza imiti ... Mubisanzwe bishaje, ibisobanuro bya A. , B, C ntaho itandukaniye cyane nuburyo bushya (ndakeka ko aribyo), na 1, 2, 3 ...... Byakoreshejwe kwerekana imbaraga.1 igereranya imbaraga z'umusaruro wa 195MPa, 2 igereranya imbaraga z'umusaruro wa 215MPa, naho 3 igereranya imbaraga z'umusaruro wa 235MPa.A3 rero ihwanye na Q235A mubirango bishya.Erega, A3 yakoreshejwe mbere, abantu benshi rero bamenyereye kuyikoresha, nkuko abandi bamenyereye gukoresha ibice bya "jin, liang".Q235 nicyuma cyubaka karubone.Ugereranije nu byiciro bishaje bya GB700-79, A3 na C3 Q345 ni ibyuma byubatswe buke.Ugereranije n amanota ashaje 1591-88, haribintu byinshi cyane nibisabwa bya 12MnV, 16Mn 16MnRE, 18Nb na 14MnNb Q345 - shaft na weldment bifite imiterere yubukanishi bwuzuye, ubushyuhe buke, plastike nziza hamwe na weldable.Zikoreshwa nkibikoresho bitwara imitwaro ifite imbaraga, ibice byubukanishi, ibyubatswe, hamwe nicyuma rusange cyubwato buciriritse kandi buto, ibigega bya peteroli, ibinyabiziga, crane, imashini zicukura amabuye y'agaciro, amashanyarazi, ibiraro, nibindi, kandi birashobora gukoreshwa mubushyuhe kuzunguruka cyangwa ibintu bisanzwe.Birashobora gukoreshwa muburyo butandukanye mukarere gakonje munsi - 40 ℃.
