Insimbi yesigaba H wuhlobo olusha lwensimbi yokwakha yezomnotho.Umumo wesigaba se-H beam uyonga futhi unengqondo, futhi izakhiwo zemishini zinhle.Lapho ugoqa, iphuzu ngalinye esigabeni linwebeka ngokulinganayo futhi ukucindezeleka kwangaphakathi kuncane.Uma kuqhathaniswa ne-I-beam evamile, inezinzuzo ze-modulus yesigaba esikhulu, isisindo esincane kanye nokonga kwensimbi, okunganciphisa isakhiwo sokwakha ngo-30-40%.Futhi ngenxa yokuthi imilenze yayo ihambisana ngaphakathi nangaphandle, ukuphela komlenze kuyi-Angle elungile, ukuhlangana nokuhlanganiswa zibe izingxenye, kungasindisa umsebenzi we-welding, riveting kuze kufike ku-25%.Ivame ukusetshenziswa ezakhiweni ezinkulu (njengamafekthri, izakhiwo eziphakeme, njll.) ezidinga umthamo omkhulu wokuthwala nokuzinza okuhle kwe-cross-section, kanye namabhuloho, imikhumbi, imishini yokuphakamisa, isisekelo semishini, ubakaki, inqwaba yesisekelo, njll.
Insimbi yesigaba sika-H iwuhlobo lwensimbi yesigaba somnotho enezakhiwo ezingcono zemishini, ethuthukisiwe futhi ithuthukiswe kusukela ku-I section steel, ikakhulukazi isigaba esinohlamvu lwesiNgisi olufanayo "H".Izici zayo zimi kanje:
I-flange ebanzi nokuqina okuphezulu kwe-lateral.
Ikhono lokugoba eliqinile, cishe ngo-5% -10% kune-I-beam.
Izindawo ezimbili ze-flange zihambisana nomunye nomunye, okwenza ukuxhumana, ukucubungula nokufakwa kube lula.
Uma kuqhathaniswa ne-welding I-beam, izindleko eziphansi, ukunemba okuphezulu, ukucindezeleka okusalayo okuphansi, asikho isidingo sezinto ezibizayo zokushisela nokutholwa kwe-weld, ukonga ukukhiqizwa kwesakhiwo sensimbi cishe ngama-30%.
Ngaphansi komthwalo wesigaba esifanayo.Isakhiwo sensimbi egoqwe eshisayo H silula ngo-15% -20% kunesakhiwo sensimbi yendabuko.
Uma kuqhathaniswa nesakhiwo sekhonkrithi, indawo yokusetshenziswa kwesakhiwo sensimbi ye-H eshisayo inganyuswa ngo-6%, futhi isisindo somzimba wesakhiwo singancishiswa ngo-20% kuya ku-30%, ngaleyo ndlela kuncishiswe amandla angaphakathi okwakhiwa kwesakhiwo.
I-H ingacutshungulwa ibe yi-T ugongolo, ugongolo lwekhekheba lezinyosi lungahlanganiswa ukuze lwenze amafomu ezigaba ezahlukahlukene, luhlangabezane kakhulu nezidingo zokuklanywa kobunjiniyela nokukhiqiza.
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 yokuphakama okufanayo kwegongolo, isakhiwo sensimbi se-bay sisikhulu ngo-50% kunesakhiwo sekhonkrithi, ukuze isakhiwo sesakhiwo 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, ukucindezeleka okusalayo okuphansi, ukubukeka okuhle kanye nekhwalithi ephezulu.
