I-variable Cross-Section I-Section Beam

Ugongolo Lwesigaba I Oluguquguqukayo Olunqamulayo – Izixazululo Zensimbi Eyenziwe Ngokwezifiso nguShenyang Zhongda

I -Variable Cross-Section I-Section Beam evela eShenyang Zhongda inikeza ukusebenza okungenakuqhathaniswa lapho iphrojekthi yakho idinga ukulungiswa komthwalo okwenziwe kahle. Uma kuqhathaniswa nezingxenye ezivamile ezifanayo, imishayo yethu ethambile, eyakhiwe ngensimbi ye-Q345C ephansi ene-alloy enobukhulu bewebhu obusukela ku-6 kuya ku-36 mm, yehlisa isisindo sensimbi ngo-20 kuya ku-30%. Njengoba sinamandla okukhiqiza ngonyaka angamathani angu-80,000, siqinisekisa yonke imishayo ngewaranti yeminyaka eyi-11 futhi senza ukuhlolwa kwe-ultrasonic okungu-100% ngaphambi kokuthunyelwa kwamanye amazwe. Amandla okudonsa okungenani angama-448 MPa, okwanelisa amazinga ebhuloho lamazwe ngamazwe kanye ne-ASTM A572 Grade 50. Isukela ku-20-50m ithunyelwa ezinsukwini ezingama-20-25, kuyilapho izixazululo ezisesitokweni zifika zingakapheli izinsuku ezi-3.

Product Incazelo

Ibanga elibanzi liyisici esisodwa nje sobunzima bakho besakhiwo; esinye ukwenza ngokuhlakanipha.

Inkinga eqhubekayo yokulahlwa kwezinto ezibonakalayo ezingxenyeni ezivamile ezigoqwayo ixazululwa yi-I-beams yethu eguquguqukayo yokujula. Sikusiza ekunciphiseni izindleko ngaphandle kokudela amandla ngokunciphisa i-web lapho izikhathi zokugoba ziphansi khona.

Izindlela zokushisela i-arc ezivame kakhulu noma ezingaphansi kwamanzi zisetshenziswa ukudala lezi zinsika. Ukuze kugcinwe ama-engeli athambile ngaphansi kokubekezelelana okungu-±2mm, yonke ingxenye ilawulwa ngokuqinile. Umphumela? Isici sesakhiwo esivumelana nokusatshalaliswa komthwalo wakho kunokukusunduzela ekubeni unjiniyela ongaphezu kovamile.

Lezi zingodo zinikeza ukuguquguquka okudingekayo emiklamo yezakhiwo eyinkimbinkimbi, okwenza zifaneleke kakhulu ophahleni lwesikhungo sokubonisa, amabhuloho abahamba ngezinyawo, kanye nezindawo zokugcina izimpahla zohlaka lwesango.
