Yiziphi izinzuzo nezici ze-H beam?

Hleyaisetshenziswa kabanzi ekwakhiweni kwesakhiwo sensimbi sanamuhla. Ingaphezulu lensimbi ye-H-section ayinakho ukuthambekela, futhi izindawo ezingaphezulu neziphansi ziyahambisana. Isici sesigaba se-H - ugongolo singcono kunesomdabuMina - ngiyabonga, insimbi yesiteshi ne-Angle steel. Ngakho yiziphi izici ze-H beam?

1. Amandla aphezulu esakhiwo

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

2. Isitayela sokuklama esiguquguqukayo nesicebile

Endabeni yobude obufanayo be-beam, isakhiwo sensimbi sikhulu ngo-50% kunesakhiwo sikakhonkolo, okwenza isakhiwo siguquguquke.

3. Isisindo esincane sesakhiwo

Uma kuqhathaniswa nesakhiwo sikakhonkolo, isisindo sesakhiwo silula, ukunciphisa isisindo sesakhiwo, ukunciphisa amandla angaphakathi okwakhiwa kwesakhiwo, kungenza izidingo zokucubungula isisekelo sesakhiwo ziphansi, ukwakhiwa kulula, izindleko kuncishisiwe.

4. Ukuzinza okuphezulu kwesakhiwo

I-hot rolled H-beam iyisakhiwo esikhulu sensimbi, isakhiwo sayo singokwesayensi futhi sinengqondo, ipulasitiki enhle nokuguquguquka, ukuzinza okuphezulu kwesakhiwo, kufanelekile ukuthwala ukudlidliza kanye nomthwalo womthelela wesakhiwo esikhulu sokwakha, ikhono eliqinile lokumelana nezinhlekelele zemvelo, ikakhulukazi ezifanele ezinye izakhiwo ezindaweni zokuzamazama komhlaba. Ngokwezibalo, emhlabeni wenhlekelele yokuzamazama komhlaba ebhubhisayo engu-7 noma ngaphezulu, insimbi emise okuka-H ikakhulukazi izakhiwo zensimbi ziye zahlupheka kancane.

5. Khulisa indawo yokusetshenziswa ngempumelelo kwesakhiwo

Uma kuqhathaniswa nesakhiwo sekhonkrithi, indawo yekholomu yesakhiwo sensimbi incane, engandisa indawo yokusetshenziswa ephumelelayo yesakhiwo, kuye ngokuthi izinhlobo ezahlukene zesakhiwo, ingandisa indawo yokusetshenziswa ephumelelayo ye-4-6%.

6. Yonga abasebenzi nezinto zokwakha

Uma kuqhathaniswa nensimbi yokushisela i-H-beam, ingasindisa kakhulu abasebenzi nezinto zokwakha, inciphise ukusetshenziswa kwezinto ezingavuthiwe, amandla nomsebenzi, ingcindezi ephansi eyinsalela, ukubukeka okuhle kanye nekhwalithi ephezulu.

7. Kulula ukucubungula ngomshini

Kulula ukunamathisela nokufaka ngokwesakhiwo, kodwa futhi kulula ukukususa nokuphinda kusetshenziswe.

8. Ukuvikelwa Kwemvelo

Ukusetshenziswa kweInsimbi ye-H-sectioningavikela ngokuphumelelayo imvelo, ebonakala ezicini ezintathu: okokuqala, uma kuqhathaniswa nokhonkolo, ingasebenzisa ukwakhiwa okomile, okubangela umsindo omncane kanye nothuli oluncane; Okwesibili, ngenxa yokunciphisa isisindo, ukukhishwa okuncane kwenhlabathi yokwakhiwa kwesisekelo, ukulimala okuncane kwezinsiza zomhlaba, ngaphezu kokunciphisa okukhulu kwenani likakhonkolo, ukunciphisa inani lokumba amatshe, okuhambisana nokuvikelwa kwemvelo; Okwesithathu, ngemva kokuba impilo yesevisi yesakhiwo sokwakha iphelelwa yisikhathi, inani lemfucumfucu eqinile elakhiwe ngemva kokuhlakazwa kwesakhiwo lincane, futhi inani lokugaywa kabusha kwezinsiza zensimbi ezilahliwe liphezulu.

9. Izinga eliphezulu lokukhiqizwa kwezimboni

Isakhiwo sensimbi esisekelwe ku-hot rolled H beam sinezinga eliphezulu lokukhiqizwa kwezimboni, esilungele ukukhiqizwa kwemishini, ukukhiqizwa okujulile, ukunemba okuphezulu, ukufakwa kalula, ukuqinisekiswa kwekhwalithi okulula, futhi kungakhiwa efektri yokukhiqiza indlu yangempela, ukukhiqizwa kwebhuloho. ifektri, imboni yokukhiqiza izitshalo zezimboni, njll. Ukuthuthukiswa kwesakhiwo sensimbi kuye kwadala futhi kwaqhuba ukuthuthukiswa kwamakhulu ezimboni ezintsha.

10. Ijubane lokwakha liyashesha

Izinyathelo ezincane, futhi zilungele ukwakhiwa kwesimo sezulu sonke, ithonya elincane lezimo zezulu. Isivinini sokwakhiwa kwesakhiwo sensimbi esenziwe nge-hot rolling H beam cishe izikhathi ezingu-2-3 zesakhiwo sekhonkrithi, izinga lokubuyisela imali liphindwe kabili, izindleko zezezimali ziyancipha, ukuze kugcinwe ukutshalwa kwezimali. Sithatha "iJinmao Tower" ePudong yaseShanghai, "isakhiwo eside kunazo zonke" eShayina njengesibonelo, indikimba eyinhloko yesakhiwo esinobude obucishe ibe ngu-400m yaqedwa esikhathini esingaphansi kwesigamu sonyaka, kuyilapho isakhiwo sikakhonkolo sensimbi sidinga ezimbili. iminyaka yokuqeda isikhathi sokwakha.
