Yiziphi izinzuzo nezici ze-H beam?

Umsebe ongu-Hisetshenziswa kabanzi ekwakhiweni kwesakhiwo sensimbi sanamuhla. Ubuso bensimbi yesigaba se-H abunawo umumo, futhi ubuso obungaphezulu nobangaphansi buhambisana. Isici sesigaba se-H - umsebe singcono kunesendabukoI - umsebe, insimbi yesiteshi kanye nensimbi ye-Angle. Ngakho-ke yiziphi izici zomsebe we-H?

1. Amandla aphezulu esakhiwo

Uma kuqhathaniswa ne-I-beam, i-section modulus inkulu, futhi isimo sokuthwala sifana ngesikhathi esifanayo, insimbi ingasindiswa ngo-10-15%.

2. Isitayela sokuklama esiguquguqukayo nesicebile

Uma ubude bomsebe bufana, isakhiwo sensimbi sikhulu ngo-50% kunesakhiwo sekhonkrithi, okwenza ukwakheka kube lula kakhulu.

3. Isisindo esincane sesakhiwo

Uma kuqhathaniswa nesakhiwo sikakhonkolo, isisindo sesakhiwo silula, ukwehla kwesisindo sesakhiwo, kunciphisa amandla angaphakathi omklamo wesakhiwo, kungenza izidingo zokucubungula isisekelo sesakhiwo sesakhiwo ziphansi, ukwakhiwa kulula, izindleko ziyancipha.

4. Ukuqina okuphezulu kwesakhiwo

I-hot rolled H-beam iyisakhiwo sensimbi esiyinhloko, isakhiwo sayo singokwesayensi futhi sinengqondo, siqinile futhi sinokuguquguquka, sizinzile kakhulu kwesakhiwo, sifanelekela ukudlidliza kanye nomthwalo wethonya wesakhiwo esikhulu sesakhiwo, sinamandla amakhulu okumelana nezinhlekelele zemvelo, ikakhulukazi ezifanele ezinye izakhiwo ezakhiweni ezindaweni zokuzamazama komhlaba. Ngokwezibalo, emhlabeni wenhlekelele yokuzamazama komhlaba ebhubhisayo engu-7 noma ngaphezulu, izakhiwo zensimbi enomfanekiso we-H ikakhulukazi zesakhiwo sensimbi zahlupheka ngezinga eliphansi kakhulu.

5. Khulisa indawo esetshenziswa kahle yesakhiwo

Uma kuqhathaniswa nesakhiwo sikakhonkolo, indawo yesigaba sekholomu yesakhiwo sensimbi incane, okungandisa indawo yokusetshenziswa ngempumelelo kwesakhiwo, kuye ngezinhlobo ezahlukene zesakhiwo, kungandisa indawo yokusetshenziswa ngempumelelo ngo-4-6%.

6. Gcina umsebenzi nezinto zokwakha

Uma kuqhathaniswa nensimbi ye-H-beam yokushisela, ingasindisa kakhulu abasebenzi nezinto zokwakha, inciphise ukusetshenziswa kwezinto zokusetshenziswa, amandla kanye nomsebenzi, ukucindezeleka okuphansi okusele, ukubukeka okuhle kanye nekhwalithi yobuso.

7. Ukucutshungulwa okulula komshini

Kulula ukunamathisela nokuyifaka ngokwesakhiwo, kodwa futhi kulula ukuyisusa nokuyisebenzisa kabusha.

8. Ukuvikelwa Kwemvelo

Ukusetshenziswa kweInsimbi yesigaba se-Hingavikela imvelo ngempumelelo, okubonakala ngezici ezintathu: okokuqala, uma kuqhathaniswa nokhonkolo, ingasebenzisa ukwakhiwa okomile, okuholela emsindweni omncane kanye nothuli oluncane; Okwesibili, ngenxa yokunciphisa isisindo, ukukhishwa okuncane kwenhlabathi yokwakha isisekelo, umonakalo omncane ezinsizeni zomhlaba, ngaphezu kokuncipha okukhulu kwenani lekhonkolo, kunciphisa inani lokumbiwa kwamadwala, okusiza ekuvikeleni imvelo; Okwesithathu, ngemva kokuphelelwa yisikhathi kwempilo yesakhiwo sesakhiwo, inani likadoti oqinile okhiqizwa ngemva kokuba isakhiwo sidiliziwe lincane, futhi inani lokuphinda kusetshenziswe izinsizakusebenza zensimbi eqoshiwe liphezulu.

9. Izinga eliphezulu lokukhiqiza kwezimboni

Isakhiwo sensimbi esisekelwe ku-hot rolled H beam sinezinga eliphezulu lokukhiqizwa kwezimboni, okulula ukukhiqizwa kwemishini, ukukhiqizwa okujulile, ukunemba okuphezulu, ukufakwa okulula, ukuqinisekiswa kwekhwalithi okulula, futhi singakhiwa sibe yifektri yokukhiqiza indlu yangempela, ifektri yokukhiqiza amabhuloho, ifektri yokukhiqiza izitshalo zezimboni, njll. Ukuthuthukiswa kwesakhiwo sensimbi kudale futhi kwaqhuba ukuthuthukiswa kwamakhulu ezimboni ezintsha.

10. Isivinini sokwakha siyashesha

Indawo encane, futhi efanelekile ukwakhiwa kwesimo sezulu sonke, ayinathonya elikhulu ezimweni zezulu. Ijubane lokwakhiwa kwesakhiwo sensimbi esenziwe ngomsebe we-H ogoqiwe oshisayo cishe liphindwe kabili-kathathu kunesakhiwo sekhonkrithi, izinga lokushintshana kwemali liphindwe kabili, izindleko zezimali ziyancishiswa, ukuze kongiwe utshalomali. Uma sibheka "iJinmao Tower" ePudong eShanghai, "isakhiwo eside kunazo zonke" eShayina njengesibonelo, umzimba oyinhloko wesakhiwo ophakeme cishe ngamamitha angu-400 waqedwa esikhathini esingaphansi kwengxenye yonyaka, kuyilapho isakhiwo sensimbi-ukhonkolo sidinga iminyaka emibili ukuqedela isikhathi sokwakha.
