Umboneleli wefektri H-udidi lwentsimbi H Beam Astm A36 Q345b H-umqadi Steel I-umqadi
inkcazelo
I-H-beam licandelo loqoqosho kunye neprofayili ephezulu esebenzayo kunye nokuhanjiswa kwendawo enqamlezileyo eyongezelelekileyo kunye nomlinganiselo ofanelekileyo wamandla-to-ubunzima. Ibizwa ngokuba icandelo layo elinqamlezayo liyafana nonobumba wesiNgesi "H". Ekubeni zonke iinxalenye ze-H-beam zicwangciswe kwii-angles ezifanelekileyo, i-H-beam ineenzuzo zokumelana nokugoba okunamandla, ukwakhiwa okulula, ukugcinwa kweendleko kunye nobunzima obulula kuzo zonke iinkalo, kwaye isetyenziswe ngokubanzi.
ukwazisa
Ubume becandelo bufana neprofayili yecandelo loqoqosho lweleta enkulu yesiLatini H, eyaziwa ngokuba yintsimbi ye-universal beam, i-wide edge (edge) I-beam okanye i-parallel flange I-beam. I-cross-section ye-H-beam idla ngokubandakanya iinxalenye ezimbini, i-web plate kunye ne-flange plate, eyaziwa ngokuba yinqeni kunye nomphetho.
sebenzisa
Imiqadi ye-H isetyenziswa kakhulu kwaye isetyenziselwa ikakhulu:
izakhiwo ezahlukeneyo zokuhlala kunye nemizi-mveliso; Izityalo ezahlukeneyo zamashishini amakhulu kunye nezakhiwo zanamhlanje eziphakamileyo, ngakumbi izityalo zemizi-mveliso kwiindawo ezinomsebenzi we-seismic rhoqo kunye neemeko zokusebenza eziphezulu zokushisa; ezifuna umthamo omkhulu wokuthwala kunye necandelo elinqamlezayo Iibhulorho ezinkulu ezinozinzo oluhle kunye nobubanzi obukhulu; izixhobo ezinzima; oohola bendlela; amathambo enqanawa; inkxaso yam; unyango lwesiseko kunye nobunjineli be-embankment; izixhobo ezahlukeneyo zoomatshini.
Ukuhlelwa
Kukho iinkcukacha ezininzi zeemveliso ze-H-beam, kwaye iindlela zokuhlela zimi ngolu hlobo lulandelayo. (1) Ngokobubanzi be-flange yemveliso, yahlulwe ibe yi-flange ebanzi, i-flange ephakathi kunye ne-flange emxinwa ye-H-beam. Ububanzi beflange B yeflange ebanzi kunye nentsimbi ephakathi yeflange H-icandelo lentsimbi inkulu okanye ilingana nobude bewebhu H. Ububanzi beflange B yeflange emxinwa H-beam iphantse ilingane nesiqingatha sobude bewebhu H. (2) Ngokutsho kokusetyenziswa kwemveliso, yahlulwe yaba yintsimbi yentsimbi emile okwe-H, ikholamu yentsimbi emilise okwe-H, imfumba yentsimbi emilise okwe-H, kunye nentsimbi emise okwentsimbi eshinyeneyo H. Ngamanye amaxesha imigudu yemilenze ehambelanayo kunye ne-trallel flange T-beams nazo zibandakanyiwe kwi-scope ye-H-beams. Ngokubanzi, i-Flange emxinwa ye-H-beam isetyenziswa njengesixhobo somthi, kwaye i-wide-flange H-beam isetyenziswa njengesixhobo sekholamu. (3) Ngokwendlela yokuvelisa, ihlulwe ibe yi-welded H-beam kwaye iqengqeleke i-H-beam. (4) Ngokobukhulu, yahlulwe yaba yi-H enkulu, ephakathi kunye nencinci. Ngokuqhelekileyo, iimveliso ezinobude bewebhu H ngaphezu kwe-700mm zibizwa ngokuba zinkulu, ezo ezinobude obungama-300 ukuya ku-700mm zibizwa ngokuba ziphakathi, kwaye ezo ezinobude obungaphantsi kwe-300mm zibizwa ngokuba zincinci. Ekupheleni kwe-1990, i-H-beam enkulu yehlabathi yayinobude bewebhu obuyi-1200mm kunye nobubanzi be-flange ye-530mm.H-beam licandelo lezoqoqosho kunye neprofayili esebenzayo kunye neprofayili ephuculweyo yokusabalalisa indawo enqamlezileyo kunye nomlinganiselo ofanelekileyo wamandla-to-ubunzima. Ibizwa ngokuba icandelo layo elinqamlezayo liyafana nonobumba wesiNgesi "H". Ekubeni zonke iinxalenye ze-H-beam zicwangciswe kwii-angles ezifanelekileyo, i-H-beam ineenzuzo zokumelana nokugoba okunamandla, ukwakhiwa okulula, ukugcinwa kweendleko kunye nobunzima obulula kuzo zonke iinkalo, kwaye isetyenziswe ngokubanzi.
