Iyini i-H-Beam ne-I-Beam
Iyini i-H-Beam?
I-H-beamiwuhlaka lohlaka lobunjiniyela olunekghono eliphezulu lokuthwala umthwalo kanye nomklamo ongasindi. Ifaneleka ngokukhethekile ezakhiweni zensimbi zanamuhla ezinama-spans amakhulu kanye nemithwalo ephezulu. Ukucaciswa kwayo okujwayelekile kanye nezinzuzo zemishini ishayela ukuqanjwa kabusha kobuchwepheshe bobunjiniyela emkhakheni wokwakha, amabhuloho, amandla, njll.
Iyini i-I-Beam?
I-beamiyinto engokongayo egobayo engaqondisiwe. Ngenxa yezindleko eziphansi nokucutshungulwa okulula, isetshenziswa kabanzi ezimeni ezifana nemishayo yesibili ezakhiweni nezisekelo zemishini. Kodwa-ke, ingaphansi kwe-H-beam ekumelaneni kwe-torsional kanye ne-multi-directional load-bearing, futhi ukukhethwa kwayo kufanele kusekelwe ngokuqinile ezidingweni zemishini.
Umehluko we-H-Beam ne-I-Beam
Umehluko obalulekile
I-H-Beam:Ama-flange (izingxenye ezivundlile ezingenhla naphansi) ze-H-beam ziyahambisana futhi ziwugqinsi olufanayo, enza isigaba esiyisikwele esimise okuphambene "H". Banikeza ukugoba okuhle kakhulu nokumelana ne-torsional, okubenza bafaneleke izakhiwo ezithwala umthwalo obalulekile.
I-Beam:Ama-flange e-I-beam mancane ngaphakathi futhi aba banzi ngaphandle, anomthambeka (ngokujwayelekile u-8% kuya ku-14%). Anesigaba esiphambanayo esimise okuka-"I", egxile ekuphikeleni ukugoba kanye nomnotho, futhi avame ukusetshenziselwa imishayo yesibili elayishwe kancane.
Ukuqhathanisa okuningiliziwe
I-H-Beam:Insimbi emise okwe-Hiyisakhiwo sebhokisi elimelana ne-torsion elakhiwe ngama-flange ahambisanayo abanzi futhi awugqinsi kanye namawebhu aqondile. Inezici zemishini ezibanzi (ukugoba okuhle kakhulu, ukugoqa, nokumelana nokucindezela), kepha izindleko zayo ziphakeme kakhulu. Isetshenziswa kakhulu ezimweni ezithwala imithwalo eyisisekelo njengamakholomu ezakhiwo eziphakeme kakhulu, ama-trusses ophahla lwefekthri amakhulu, kanye nemishayo ye-crane esindayo.
I-Beam:I-imishayolondoloza izinto zokwakha futhi unciphise izindleko ngenxa yomklamo wazo we-flange slope. Asebenza kahle kakhulu lapho egobe ngendlela engaqondile, kodwa anokumelana ne-torsion okubuthakathaka. Zifanele ukulayishwa kancane, izingxenye zesibili ezifana nemishayo yesibili yefektri, izisekelo zemishini, nezakhiwo zesikhashana. Empeleni ziyisixazululo esingokomnotho.
Izimo Zokusebenza ze-H-Beam ne-I-Beam
I-H-Beam:
1. Izakhiwo ezinde kakhulu (njenge-Shanghai Tower) - amakholomu ane-flange ebanzi amelana nokuzamazama komhlaba kanye ne-torque yomoya;
2. Amapulangwe ophahla lwezitshalo zezimboni ezinkulu - ukumelana nokugoba okuphezulu kusekela ama-cranes asindayo (amathani angama-50 nangaphezulu) kanye nemishini yophahla;
3. Ingqalasizinda yamandla - amafreyimu ensimbi e-thermal power plant boilers amelana nokucindezela namazinga okushisa aphezulu, futhi imibhoshongo ye-turbine yomoya inikeza ukusekelwa kwangaphakathi ukumelana nokudlidliza komoya;
4. Amabhuloho asebenza kanzima - izinsimbi zamabhuloho awela ulwandle amelana nemithwalo eguquguqukayo yezimoto kanye nokugqwala kwamanzi olwandle;
5. Imishini enzima - izisekelo ze-hydraulic yezimayini kanye nezikebhe zomkhumbi zidinga i-matrix ephezulu yokudonsa nokukhathala.
I-Beam:
1. Amapulangwe ophahleni lwesakhiwo semboni - Ama-angled flange asekela kahle amapuleti ensimbi ahlanganiswe ngombala (ama-span <15m), anenani eliphansi ngo-15% -20% kune-H-beam.
2. Izinto ezisetshenziswayo ezingasindi kakhulu - Amathrekhi e-Conveyor namafreyimu eplathifomu amancane (umthamo womthwalo
3. Izakhiwo zesikhashana - Imishayo yesikafula yokwakha kanye namakholomu okusekela amashede ombukiso ahlanganisa ukuhlanganisa nokuhlakazwa ngokushesha ngokungenga kwezindleko.
4. Amabhuloho anemithwalo ephansi - Amabhuloho asekelwe kalula emigwaqweni yasemaphandleni (ama-span angu-20m) athuthukisa ukumelana kwawo nokugoba ngendlela engabizi.
5. Izisekelo zemishini - Izisekelo zamathuluzi omshini namafreyimu emishini yezolimo zisebenzisa isilinganiso sazo sokuqina sokuqina kwesisindo.
