Ziziphi iingenelo kunye neempawu ze-H beam?

Umqadi we-Hisetyenziswa kakhulu kulwakhiwo lwesakhiwo sentsimbi sanamhlanje. Umphezulu wentsimbi yecandelo le-H awunakuthambekela, kwaye iindawo eziphezulu nezisezantsi ziyafana. Uphawu lwecandelo le-H - umqadi lungcono kunelo lwendabuko.I - umqadi, intsimbi yetshaneli kunye nentsimbi ye-Angle. Ngoko ke zithini iimpawu ze-H beam?

1. Amandla aphezulu olwakhiwo

Xa kuthelekiswa ne-I-beam, i-section modulus inkulu, kwaye imeko yokuthwala iyafana ngexesha elinye, isinyithi singasindiswa nge-10-15%.

2. Isitayile soyilo esiguquguqukayo nesityebileyo

Kwimeko yokuphakama kwebham efanayo, isakhiwo sentsimbi sikhulu ngama-50% kunesakhiwo sekhonkrithi, nto leyo eyenza uyilo lube bhetyebhetye ngakumbi.

3. Ubunzima obuphantsi besakhiwo

Xa kuthelekiswa nesakhiwo sekhonkrithi, ubunzima besakhiwo bulula, ukunciphisa ubunzima besakhiwo, ukunciphisa amandla angaphakathi oyilo lwesakhiwo, kunokwenza iimfuno zokucubungula isiseko sesakhiwo sesakhiwo zibe phantsi, ulwakhiwo lulula, iindleko ziyancitshiswa.

4. Uzinzo oluphezulu lwesakhiwo

I-H-beam egobileyo eshushu yeyona sakhiwo sentsimbi siphambili, isakhiwo sayo sesayensi kwaye sifanelekile, silungile kwaye sinokuguquguquka, sizinzo oluphezulu lwesakhiwo, sifanelekile ukungcangcazela kunye nomthwalo wempembelelo yesakhiwo esikhulu sesakhiwo, sinamandla okumelana neentlekele zemvelo, ngakumbi ezifanelekileyo kwezinye izakhiwo kwiindawo zenyikima. Ngokwezibalo, kwihlabathi lentlekele yenyikima enkulu enobukhulu obusi-7 nangaphezulu, izakhiwo zesinyithi ezinobume obungu-H azizange zifumane mgangatho uphezulu.

5. Yandisa indawo yokusetyenziswa ngokufanelekileyo kwesakhiwo

Xa kuthelekiswa nesakhiwo sekhonkrithi, indawo yecandelo lekholamu yesakhiwo sentsimbi incinci, nto leyo enokunyusa indawo yokusetyenziswa ngokufanelekileyo kwesakhiwo, kuxhomekeke kwiintlobo ezahlukeneyo zesakhiwo, inokunyusa indawo yokusetyenziswa ngokufanelekileyo ye-4-6%.

6. Gcina abasebenzi kunye nezixhobo

Xa kuthelekiswa nentsimbi ye-H-beam yokuwelda, inokonga kakhulu abasebenzi kunye nezixhobo, inciphise ukusetyenziswa kwezinto ezikrwada, amandla kunye nomsebenzi, uxinzelelo oluphantsi olushiyekileyo, inkangeleko entle kunye nomgangatho womphezulu.

7. Ukucutshungulwa okulula koomatshini

Kulula ukuyifaka nokuyincamathisela ngokwesakhiwo sayo, kodwa kulula ukuyisusa nokuyiphinda uyisebenzise.

8. Ukhuseleko lweNdalo

Ukusetyenziswa kweIntsimbi yecandelo le-Hinokukhusela ngokufanelekileyo okusingqongileyo, nto leyo ebonakala kwiinkalo ezintathu: okokuqala, xa kuthelekiswa nekhonkrithi, ingasebenzisa ulwakhiwo olomileyo, nto leyo ebangela ingxolo encinci kunye nothuli oluncinci; Okwesibini, ngenxa yokunciphisa ubunzima, ukutsalwa komhlaba okuncinci xa kusakhiwa isiseko, umonakalo omncinci kwizixhobo zomhlaba, ukongeza ekunciphiseni okukhulu kwinani lekhonkrithi, kunciphisa ubungakanani bokwembiwa kwamatye, okunceda ekukhuselweni kokusingqongileyo; Okwesithathu, emva kokuba ixesha lokusebenza kwesakhiwo sesakhiwo liphelile, ubungakanani benkunkuma eqinileyo eveliswa emva kokuba isakhiwo sichithiwe buncinci, kwaye ixabiso lokurisayikilisha lezixhobo zentsimbi elahliweyo liphezulu.

9. Inqanaba eliphezulu lemveliso yemizi-mveliso

Isakhiwo sentsimbi esisekelwe kwi-hot rolled H beam sinezinga eliphezulu lemveliso yemizi-mveliso, elungele ukwenziwa koomatshini, imveliso enzulu, ukuchaneka okuphezulu, ukufakwa okulula, ukuqinisekiswa komgangatho okulula, kwaye sinokwakhiwa sibe yifektri yokuvelisa indlu yokwenyani, ifektri yokuvelisa iibhulorho, ifektri yokuvelisa izityalo zoshishino, njl. Uphuhliso lwesakhiwo sentsimbi ludale kwaye luqhubele phambili uphuhliso lwamakhulu emizi-mveliso emitsha.

10. Isantya sokwakha siyakhawuleza

Indawo encinci, kwaye ifanelekile ukwakhiwa kwemozulu yonke, ayinampembelelo ingako kwiimeko zemozulu. Isantya sokwakhiwa kwesakhiwo sentsimbi esenziwe ngomqadi we-H oshushu siphindwe kabini kunesakhiwo sekhonkrithi, izinga lokutshintsha kwemali liphindwe kabini, iindleko zemali ziyancitshiswa, ukuze kongiwe utyalo-mali. Xa kuthathwa "iJinmao Tower" ePudong eShanghai, "isakhiwo eside" eTshayina njengomzekelo, umzimba oyintloko wesakhiwo esinobude obuphantse bube yi-400m sagqitywa ngaphantsi kwesiqingatha sonyaka, ngelixa isakhiwo sentsimbi nekhonkrithi sathatha iminyaka emibini ukugqiba ixesha lokwakhiwa.
