Yintoni i-H-Beam kunye ne-I-Beam
Yintoni i-H-Beam?
H-umqadisisixhobo sobunjineli samathambo esinemveliso ephezulu yokuthwala umthwalo kunye noyilo olukhaphukhaphu. Ngokukodwa ifanelekile kwizakhiwo zetsimbi zanamhlanje kunye neendawo ezinkulu kunye nemithwalo ephezulu. Ukucaciswa kwayo okusemgangathweni kunye neenzuzo zoomatshini ziqhuba ubuchwephesha bobunjineli bobunjineli kwiindawo zokwakha, iibhulorho, amandla, njl.
Yintoni I-Beam?
I-beamyimathiriyeli yolwakhiwo olugobayo olungagungqiyo olunoqoqosho. Ngenxa yeendleko eziphantsi kunye nokucutshungulwa lula, isetyenziswa ngokubanzi kwiimeko ezifana nemigangatho yesibini kwizakhiwo kunye nokuxhaswa koomatshini. Nangona kunjalo, ingaphantsi kwe-H-beam ekuchaseni i-torsional kunye ne-multi-directional load-bearing, kwaye ukhetho lwayo kufuneka lusekelwe ngokuthe ngqo kwiimfuno zoomatshini.
Umahluko we-H-Beam kunye ne-I-Beam
Umahluko obalulekileyo
H-Beam:Iiflange (amacandelo aphezulu nasezantsi axwesileyo) omqadi we-H ayanxusene kwaye anobukhulu obufanayo, zenza isikwere "H"-icandelo elinqamlezileyo elimilisekileyo. Banikezela ngokugoba okugqwesileyo kunye nokumelana ne-torsional, okwenza ukuba bafaneleke kwizakhiwo ezithwala umthwalo ongundoqo.
I-Beam:Ii-flanges ze-I-beam zincinci ngaphakathi kwaye zibanzi ngaphandle, kunye ne-slope (ngokuqhelekileyo i-8% ukuya kwi-14%). Zinecandelo elinqamlezileyo elithi "I", eligxile kwi-unidirectional ukugoba kunye noqoqosho, kwaye zihlala zisetyenziselwa imiqadi yesibini elayishwe kancinci.
Uthelekiso oluneenkcukacha
H-Beam:Intsimbi emile okwe-Hsisakhiwo sebhokisi esixhathisayo kwi-torsion eyenziwe bububanzi obufanayo kunye neeflange ezityebileyo ezinxuseneyo kunye neewebhu ezithe nkqo. Ineempawu ezibanzi zoomatshini (ukugoba okugqwesileyo, ukugoba, kunye nokumelana noxinzelelo), kodwa ixabiso layo liphezulu. Isetyenziswa ikakhulu kwiimeko ezithwele umthwalo ongundoqo onje ngeentsika eziphakamileyo zokwakha, iitrasi ezinkulu zophahla lwefektri, kunye nemiqadi enzima yecrane.
I-Beam:I-imiqadigcina imathiriyeli kwaye unciphise iindleko enkosi kuyilo lwethambeka leflange. Zisebenza kakuhle kakhulu xa ziphantsi kokugoba unidirectional, kodwa zinokuxhathisa okubuthathaka. Zifanele ukulayishwa kancinci, iinxalenye zesibini ezifana nemigangatho yesibini yefektri, izixhobo ezixhasayo, kunye nezakhiwo zexeshana. Zisisisombululo esinoqoqosho.
Iimeko zeSicelo se-H-Beam kunye ne-I-Beam
H-Beam:
1. Izakhiwo eziphakamileyo kakhulu (ezifana neShailand Tower) - iikholamu ezibanzi-flange zixhathisa iinyikima kunye netorque yomoya;
2. Iitrasi ezinkulu zophahla lweplanti yemizi-mveliso - ukumelana nokugoba okuphezulu kuxhasa iikhreyini ezinzima (iitoni ezingama-50 ukuya phezulu) kunye nezixhobo zophahla;
3. Iziseko zamandla ombane - i-thermal power plant boiler steel frames ukumelana noxinzelelo kunye nobushushu obuphezulu, kunye neetower turbine tower zibonelela ngenkxaso yangaphakathi ukuxhathisa ukungcangcazela komoya;
4. Iibhulorho ezinomsebenzi onzima – iibhulorho ezinqumla ulwandle ziyayixhathisa imithwalo eguquguqukayo yezithuthi kunye nokudleka kwamanzi olwandle;
5. Oomatshini obunzima - i-mining hydraulic supports kunye neenqanawa zeenqanawa zifuna i-matrix ephezulu ye-torsion kunye ne-fatigue-resistant.
I-Beam:
1. I-purlins yesakhiwo sokwakha i-industrial - ii-angled flanges zixhasa ngokufanelekileyo iipleyiti zensimbi ezinombala (i-spans <15m), kunye neendleko ze-15% -20% ngaphantsi kwe-H-beams.
2. Izixhobo ezilula zixhasa - Iingoma zokuhambisa kunye nezakhelo ezincinci zeqonga (umthamo womthwalo
3. Izakhiwo zexeshana - Imiqadi ye-scaffolding yokwakha kunye neekholamu zenkxaso yeshedi yomboniso idibanisa ukudibanisa ngokukhawuleza kunye nokuchithwa kunye neendleko-zokusebenza.
4. Iibhulorho ezinomthwalo ophantsi - Iibhulorho zemiqadi ezixhaswe ngokulula kwiindlela zasemaphandleni (i-spans <20m) ziphakamisa ukuxhathisa kwazo ukugoba okungabizi kakhulu.
5. Iziseko zoomatshini - Iziseko zezixhobo zoomatshini kunye nezakhelo zoomatshini bezolimo zisebenzisa ukuqina kwazo okuphezulu kumlinganiselo wobunzima.
