Isingeniso Esiyisisekelo se-H-Beam
1. Incazelo kanye Nesakhiwo Esiyisisekelo
Ama-Flanges: Amapuleti amabili ahambisanayo, avundlile obubanzi obufanayo, aphethe umthwalo wokugoba oyinhloko.
Iwebhu: Ingxenye emaphakathi eqondile exhuma ama-flange, ukumelana namandla okugunda.
II-H-beamIgama lika-"H" -elifana ne-cross-sectional shape. Ngokungafani neI-beam(I-i-beam), ama-flanges ayo abanzi futhi ayisicaba, ahlinzeka ukumelana okukhulu namandla okugoba kanye nama-torsional.
2. Izici Zobuchwepheshe Nemininingwane
Izinto zokwakha kanye namazinga: Izinto zensimbi ezisetshenziswa ngokuvamile zifaka i-Q235B, i-A36, i-SS400 (insimbi ye-carbon), noma i-Q345 (insimbi ye-low-alloy), ehambisana nezindinganiso zamazwe ngamazwe njenge-ASTM ne-JIS.
Ibanga likasayizi (izicaciso ezijwayelekile):
| Ingxenye | Ibanga lepharamitha |
| Ubude bewebhu | 100-900 mm |
| Ukujiya kwewebhu | 4.5–16 mm |
| Ububanzi be-Flange | 100-400 mm |
| Ubukhulu be-Flange | 6–28 mm |
| Ubude | Okujwayelekile okungu-12m (kungenziwa ngokwezifiso) |
Inzuzo yamandla: Idizayini ebanzi ye-flange ilungiselela ukusatshalaliswa komthwalo, futhi ukumelana nokugoba kungaphezulu kuka-30% ngaphezu kwalokho kwe-I-beam, okuyenza ifaneleke izimo zomthwalo osindayo.
3. Izicelo Eziyinhloko
Izakhiwo Zokwakha: Amakholomu ezakhiweni eziphakeme kanye nezinsimbi zophahla ezimbonini ezithatha indawo enkulu anikeza ukusekela okuyisisekelo okuthwala umthwalo.
Amabhuloho Nemishini Enzima: Ama-Crane girders namabhuloho amabhuloho kufanele amelane nemithwalo enamandla kanye nokucindezeleka kokukhathala.
Imboni Nezokuthutha: Izitezi zomkhumbi, i-chassis yesitimela, nezisekelo zemishini zithembele kumandla azo aphezulu nasezimpahleni ezingasindi.
Izicelo Ezikhethekile: Izinduku zokuxhuma zohlobo lwe-H ezinjinini zezimoto (njengenjini ye-Audi 5-cylinder) zenziwe ngokwenziwa zisuka ku-4340 chromium-molybdenum steel ukuze zimelane namandla aphezulu nesivinini.
4. Izinzuzo kanye nezici ezibalulekile
Ezomnotho: Isilinganiso esiphezulu samandla nesisindo sinciphisa ukusetshenziswa kwezinto ezibonakalayo kanye nezindleko zizonke.
Ukuzinza: Izakhiwo ezinhle kakhulu ezivumelana nezimo neziguquguqukayo ziyenza ifaneleke ngokukhethekile izakhiwo ezisezindaweni ezithandwa ukuzamazama komhlaba noma ezingaphansi kwemithwalo ephezulu yomoya.
Ukwakhiwa Okulula: Ukuxhumana okujwayelekile kwenza kube lula ukuxhumana nezinye izakhiwo (ezifana nokushisela nokufaka ibhawudi), zifinyeze isikhathi sokwakha.
Ukuqina: I-Hot-rolling ithuthukisa ukumelana nokukhathala, okuholela empilweni yesevisi engaphezu kweminyaka engama-50.
5. Izinhlobo Ezikhethekile Nezinhlobonhlobo
Wide Flange Beam (Viga H Alas Anchas): Ifaka ama-flange abanzi, asetshenziselwa izisekelo zemishini esindayo.
I-HEB Beam: Ama-flange ahambisanayo anamandla aphezulu, aklanyelwe ingqalasizinda enkulu (njengamabhuloho wesitimela anesivinini esikhulu).
I-Laminated Beam (Viga H Laminada): I-Hot-rolled ukuze i-weldability ethuthukisiwe, ifanele amafreyimu esakhiwo sensimbi ayinkimbinkimbi.
Ukusetshenziswa kwe-H-Beam
1. Izakhiwo zokwakha:
Civil Construction: Isetshenziswa ezakhiweni zokuhlala nezohwebo, ezihlinzeka ngosekelo lwesakhiwo.
Izimboni zezimboni: I-H-imishayozidume kakhulu ezitshalweni ezine-span enkulu kanye nezakhiwo eziphakeme ngenxa yomthamo wazo omuhle kakhulu wokuthwala nokusimama.
Izakhiwo Eziphakeme Eziphakeme: Amandla aphezulu nokuzinza kwama-H-beams awenza abe yinketho ekahle ezindaweni ezithandwa ukuzamazama komhlaba nezimo ezishisa kakhulu.
2. Ubunjiniyela Bebhuloho:
Amabhuloho Amakhulu: I-H-imishayo isetshenziselwa izakhiwo ze-beam kanye nekholomu yamabhuloho, ukuhlangabezana nezidingo ze-spans ezinkulu kanye nomthamo ophezulu wokuthwala umthwalo.
3. Ezinye Izimboni:
Izinto Ezisindayo: Imishayo ye-H isetshenziselwa ukusekela imishini esindayo nemishini.
Imigwaqo emikhulu: Isetshenziswa kumabhuloho nezakhiwo zemibhede yomgwaqo.
Thumela amafreyimu: Amandla nokumelana nokugqwala kwe-H-imishayo kubenza bafaneleke ukwakha umkhumbi.
Ukusekela Kwamayini:Isetshenziswa ezakhiweni zokusekela ezimayini ezingaphansi komhlaba.
Ukuthuthukiswa Komhlaba kanye Nobunjiniyela Bamadamu: Imishayo ye-H ingasetshenziswa ukuqinisa izisekelo namadamu.
Izingxenye Zomshini: Izinhlobonhlobo zamasayizi kanye nokucaciswa kwe-H-imishayo nakho kuwenza abe yingxenye evamile ekukhiqizeni umshini.
