Iimbonakalo:
Imiqadi ye-H eshushu eqengqelekayo isasaza ngokufanelekileyo umlinganiselo wecandelo lobungakanani becandelo ngokweenjongo ezahlukeneyo, kwaye ineempawu ezibalaseleyo zoomatshini kunye nokusebenza okuphezulu kokusetyenziswa.
Amandla aphezulu esakhiwo.Xa kuthelekiswa ne-I-beam, i-modulus yecandelo likhulu, kwaye isinyithi sinokugcinwa ngo-10-15% phantsi kweemeko ezifanayo zokuthwala.
Isitayela soyilo siguquguqukayo kwaye sisityebi.Kwimeko yobude obufanayo be-boam, i-bay yesakhiwo sensimbi ingaba yi-50% enkulu kune-concrete structure bay, ngaloo ndlela yenza isakhiwo sesakhiwo sibe bhetyebhetye.
Isakhiwo silula.Xa kuthelekiswa nesakhiwo sekhonkrithi, ilula kunesakhiwo sekhonkrithi, kwaye ubunzima besakhiwo buyancipha, obunciphisa amandla angaphakathi oyilo lwesakhiwo, olunokwenza isiseko sokwakhiwa kweemfuno zonyango oluphantsi, ulwakhiwo olulula kunye neendleko eziphantsi.
Isakhiwo sensimbi ngokukodwa esenziwe ngentsimbi ye-H-section ye-hot-rolled inesakhiwo sesayensi kunye nengqiqo, iplastiki enhle kunye nokuguquguquka, kunye nokuzinza okuphezulu kwesakhiwo.Kufanelekile ukwakha izakhiwo ezimelana nokungcangcazela okukhulu kunye nemithwalo yempembelelo.Inokuchasana okunamandla kwiintlekele zendalo, kwaye ifaneleke ngokukodwa kwabaninzi Isakhiwo sokwakha kwindawo yenyikima.Ngokwezibalo, kwiintlekele zenyikima ezitshabalalisayo zehlabathi ezikwi-7 okanye ngaphezulu, izakhiwo zentsimbi ezilawulwa yintsimbi emile okwe-H ziye zafumana owona monakalo mncinane.
Yandisa indawo esebenzayo yokusetyenziswa kwesakhiwo.Xa kuthelekiswa nesakhiwo sekhonkrithi, ikholomu yesakhiwo sensimbi inendawo encinci ye-cross-sectional, enokunyusa indawo yokusetyenziswa ngokufanelekileyo kwesakhiwo.Ngokuxhomekeke kwindlela eyahlukileyo yesakhiwo, inokunyusa indawo yokusetyenziswa ngokufanelekileyo nge-4-6%.
Xa kuthelekiswa nokuwelda intsimbi emise okwe-H, inokusindisa kakhulu abasebenzi kunye nezixhobo, ukunciphisa ukusetyenziswa kwezixhobo, amandla kunye nabasebenzi, kunye noxinzelelo lwentsalela ephantsi, kunye nenkangeleko entle kunye nomgangatho womphezulu.
Ilungele ukwenziwa ngoomatshini, uqhagamshelo lolwakhiwo kunye nofakelo, kwaye kulula ukuyiqhaqha kunye nokusetyenziswa kwakhona.
Ukusetyenziswa kwentsimbi yecandelo le-H kunokukhusela ngokufanelekileyo indawo engqongileyo, ebonakaliswa kwiinkalo ezintathu: okokuqala, xa kuthelekiswa nekhonkrithi, ukwakhiwa okomileyo kunokusetyenziswa, okuvelisa ingxolo encinci kunye nothuli oluncinci;okwesibini, ngenxa yobunzima obulula, ubungakanani bomhlaba obuthathiweyo bokwakhiwa kwesiseko buncinci.Umonakalo wobutyebi bomhlaba mncinane.Ukongezelela, ukunciphisa okukhulu kwinani lekhonkrithi kunye nokwembiwa kweentaba kunenzuzo ekukhuseleni indawo yendalo;okwesithathu, emva kokuba ubomi benkonzo yesakhiwo sokwakha buphela, inani lenkunkuma eqinileyo eyenziwa emva kokuchithwa kwesakhiwo sincinci, kwaye ixabiso lokuhlaziywa kwezixhobo zensimbi ezilahliweyo liphezulu.
Isakhiwo sensimbi ngokukodwa esenziwe nge-hot-rolled H-beam sinezinga eliphezulu lokuveliswa kwemveliso, ekulungele ukuveliswa koomatshini, ukuveliswa okunzulu, ukuchaneka okuphezulu, ukufakela okulula, kunye nokulula ukuqinisekisa umgangatho.Inokwakhelwa kumzi mveliso wokwenyani wendlu, umzi-mveliso wokwenza ibhulorho, umzi-mveliso wokwenza umzi-mveliso, njl.Uphuhliso lwezakhiwo zetsimbi luye lwadala kwaye lwakhuthaza ukuphuhliswa kwamakhulu amashishini asakhasayo.
Isantya sokwakhiwa kweprojekthi sikhawuleza, indawo encinci, kwaye ifanelekile ukwakhiwa kwemozulu yonke, kwaye ayichaphazeli kakhulu kwiimeko zemozulu.Isantya sokwakhiwa kwesakhiwo sensimbi esenziwe ngentsimbi ye-H-section ye-hot-rolled malunga ne-2-3 yesakhiwo sekhonkrithi, i-capital turnover rate iphindwe kabini, kwaye iindleko zemali ziyancitshiswa, ngaloo ndlela zigcina utyalo-mali.Thatha “iJinmao Building” ePudong, eShanghai, “esona sakhiwo siphakamileyo” kwilizwe lam njengomzekelo.Umzimba oyintloko wesakhiwo kunye nobude bomzimba obusondeleyo malunga ne-400 m ugqibe uphahla lwesakhiwo ngaphantsi kwesiqingatha sonyaka, ngelixa isakhiwo sentsimbi-ikhonkrithi sifuna iminyaka emibini yokwakha.
