Ungayikhetha Kanjani I-H Beam Efanele Embonini Yokwakha?

Embonini yokwakha,Imisebe ye-Hzaziwa ngokuthi "umgogodla wezakhiwo ezithwala imithwalo"—ukukhetha kwazo okunengqondo kunquma ngqo ukuphepha, ukuqina, kanye nokusebenza kahle kwamaphrojekthi. Ngokwanda okuqhubekayo kokwakhiwa kwengqalasizinda kanye nezimakethe zezakhiwo eziphakeme, indlela yokukhetha imishayo ye-H efanelana nezidingo zephrojekthi ezinhlobonhlobo zemikhiqizo isibe yinkinga eyinhloko konjiniyela kanye namaqembu okuthenga. Ngezansi umhlahlandlela onemininingwane ogxile ezimfanelweni ezibalulekile, izici ezihlukile, kanye nezimo zokusetshenziswa kwemishayo ye-H ukusiza abadlali bemboni benze izinqumo zesayensi.

Qala Ngezimfanelo Eziyinhloko: Qonda "Izindinganiso Eziyisisekelo" ze-H Beams

Ukukhethwa kwemishayo ye-H kumele kuqala kusekelwe ezimfanelweni ezintathu eziyinhloko ezingaxoxiswani, njengoba lezi zihlobene ngqo nokuthi umkhiqizo ungahlangabezana yini nezidingo zomklamo wesakhiwo.

Ibanga Lezinto EzibalulekileIzinto ezivame kakhulu zemishayo ye-H yinsimbi yesakhiwo sekhabhoni (njengeI-Q235B, i-Q355B H Beamezindinganisweni zaseShayina, nomaUgongolo lwe-A36, A572 Hngokwezindinganiso zaseMelika) kanye nensimbi enamandla aphezulu ene-alloy ephansi. I-Q235B/A36 H Beam ifanelekela ukwakhiwa kwezakhiwo zomphakathi okujwayelekile (isb., izakhiwo zokuhlala, amafektri amancane) ngenxa yokushibilika kwayo okuhle kanye nezindleko eziphansi; I-Q355B/A572, enamandla aphezulu okukhiqiza (≥355MPa) kanye namandla okudonsa, ikhethwa kakhulu kumaphrojekthi anzima njengamabhuloho, ama-workshop amakhulu, kanye nama-cores ezakhiwo eziphakeme, njengoba inganciphisa usayizi we-cross-section we-beam futhi yonge isikhala.

Imininingwane Yobukhulu: Imishayo ye-H ichazwa ngobukhulu obuthathu obuyinhloko: ukuphakama (H), ububanzi (B), kanye nobukhulu bewebhu (d). Isibonelo, imishayo ye-H ebhalwe ukuthi "H300×150×6×8"kusho ukuthi inokuphakama okungu-300mm, ububanzi obungu-150mm, ubukhulu bewebhu obungu-6mm, kanye nobukhulu be-flange obungu-8mm. Imishayo ye-H encane (H≤200mm) ivame ukusetshenziselwa izakhiwo zesibili njengezihlanganisi zephansi kanye nezisekelo zokuhlukanisa; eyobukhulu obuphakathi (200mm＜H＜400mm) isetshenziswa ezinsikeni eziyinhloko zezakhiwo ezinezitezi eziningi kanye nophahla lwefektri; imishayo ye-H enkulu (H≥400mm) ibalulekile ezikhungweni eziphakeme kakhulu, amabhuloho amade, kanye namapulatifomu emishini yezimboni.

Ukusebenza Kwemishini: Gxila ezinkombeni ezinjengokuqina kokukhiqiza, amandla okudonsa, kanye nokuqina komthelela. Kumaphrojekthi asezindaweni ezibandayo (isb., enyakatho yeShayina, eCanada), imisebe ye-H kumele iphumelele ukuhlolwa komthelela okushisa okuphansi (njengokuqina komthelela okungu-40℃ ≥34J) ukuze kugwenywe ukuphuka okubuthakathaka ezimweni zokubanda; ezindaweni zokuzamazama komhlaba, imikhiqizo ene-ductility enhle (ukunwebeka okungu-≥20%) kufanele ikhethwe ukuze kuthuthukiswe ukumelana nokuzamazama komhlaba kwesakhiwo.

Sebenzisa Izici Ezihlukile: Qondanisa "Izinzuzo Zomkhiqizo" Nezidingo Zephrojekthi

Uma kuqhathaniswa nezingxenye zensimbi zendabuko ezifanaImishayo ye-Ikanye nezinsimbi zesiteshi, imishayo ye-H inezici ezihlukile zesakhiwo ezenza zifanelekele izimo ezithile zokwakha—ukuqonda lezi zinzuzo kuyisihluthulelo sokukhetha okuqondiwe.

Ukusebenza Kahle Kokuthwala Imithwalo Okuphezulu: Ingxenye ye-cross-section ye-H beams emise okwe-H isabalalisa izinto ngendlela enengqondo: ama-flange aqinile (izingxenye eziphezulu nezingezansi ezivundlile) athwala ingxenye enkulu yesikhathi sokugoba, kuyilapho i-web encane (ingxenye ephakathi eqondile) imelana namandla okucheba. Lo mklamo uvumela i-H beams ukuthi ifinyelele umthamo ophezulu wokuthwala umthwalo ngokusetshenziswa okuncane kwensimbi—uma kuqhathaniswa ne-I-beams enesisindo esifanayo, i-H beams inamandla okugoba aphezulu ngo-15%-20%. Lesi sici siyenza ibe yindawo ekahle kumaphrojekthi aphishekela ukonga izindleko kanye nezakhiwo ezilula, njengezakhiwo ezenziwe ngaphambilini kanye nokwakhiwa kwe-modular.

Ukuqina Okuqinile Nokufakwa Okulula: I-symmetric H cross-section inciphisa ukuguquguquka kwe-torsional ngesikhathi sokwakha, okwenza imishayo ye-H izinze kakhulu uma isetshenziswa njengemishayo eyinhloko ethwala umthwalo. Ngaphezu kwalokho, ama-flange awo ayisicaba kulula ukuwaxhuma nezinye izingxenye (isb. ama-bolts, ama-welds) ngaphandle kokucubungula okuyinkimbinkimbi—lokhu kunciphisa isikhathi sokwakha endaweni ngo-30% uma kuqhathaniswa nezingxenye zensimbi ezingajwayelekile, okubalulekile kumaphrojekthi asheshayo njengezakhiwo zezentengiselwano kanye nengqalasizinda yezimo eziphuthumayo.

Ukugqwala Okuhle Nokumelana Nomlilo (ngokwelashwa): Imishayo ye-H engacutshungulwanga ivame ukugqwala, kodwa ngemva kokwelashwa kwendawo efana nokushisa okushisayo noma i-epoxy coating, ingamelana nokugqwala ezindaweni ezinomswakama noma ezisogwini (isb., amapulatifomu asogwini, imigwaqo yasogwini). Ezimweni zokushisa okuphezulu njengezindawo zokusebenzela zezimboni ezinezitofu, imishayo ye-H engamelani nomlilo (embozwe ngopende ovimbela umlilo ongaphakathi) ingagcina amandla okuthwala umthwalo isikhathi esingaphezu kwemizuzu engu-120 uma kwenzeka umlilo, ihlangabezana nezindinganiso zokuphepha komlilo eziqinile.

Izimo Zokusetshenziswa Okuqondiwe: Ukukhetha Okufanele

Amaphrojekthi okwakha ahlukene anezidingo ezahlukahlukene ze-H-beams. Inani lawo lingakhuliswa kuphela ngokuvumelanisa izakhiwo zomkhiqizo nezidingo zesayithi. Lokhu okulandelayo yizimo ezintathu ezijwayelekile zokusetshenziswa kanye nokuhlanganiswa okunconywayo.

Izakhiwo Zokuhlala Nezokuhweba Eziphakeme: Ezakhiweni ezinezitezi ezingu-10-30, kunconywa imisebe ye-H-gauge ephakathi eyenziwe ngensimbi ye-Q355B (H250×125×6×9 kuya ku-H350×175×7×11). Amandla azo aphezulu asekela isisindo sezitezi eziningi, kanti usayizi wazo omncane usindisa isikhala sokuklama kwangaphakathi.

Amabhuloho kanye nezakhiwo ezinde: Amabhuloho amade (amamitha angu-≥50) noma ophahleni lwenkundla adinga imisebe emikhulu, eqinile kakhulu (H400×200×8×13 noma ngaphezulu).

Izitshalo Zezimboni Nezindawo Zokugcina Izimpahla: Izitshalo ezithwala kanzima (njengezitshalo zokukhiqiza izimoto) kanye nezindawo zokugcina impahla ezinkulu zidinga imisebe ye-H ekwazi ukusekela isisindo semishini noma ukulayisha imithwalo.
