Embonini yezokwakha,H imishayozaziwa ngokuthi "umgogodla wezakhiwo ezithwala imithwalo"—ukukhethwa kwazo okunengqondo kunquma ngokuqondile ukuphepha, ukuqina, kanye nokusebenza kahle kwezindleko zamaphrojekthi. Ngokunwetshwa okuqhubekayo kokwakhiwa kwengqalasizinda kanye nezimakethe zezakhiwo eziphakeme, indlela yokukhetha imishayo engu-H ehambisana nezidingo zephrojekthi emikhiqizweni eminingi sekuyinkinga eyinhloko konjiniyela nasemaqenjini okuthenga. Ngezansi kukhona umhlahlandlela onemininingwane ogxile kuzibaluli eziyinhloko, izici ezihlukile, nezimo zohlelo lokusebenza lwe-H lemishayo ukusiza abadlali bemboni benze izinqumo zesayensi.

Qala Ngezibaluli Eziyinhloko: Bamba "Amazinga Ayisisekelo" we-H Beams

Ukukhethwa kwemishayo engu-H kufanele kuqala kusekelwe kuzibaluli ezintathu eziyinhloko okungaxoxiswana ngazo, njengoba lezi zihlobana ngokuqondile nokuthi umkhiqizo ungakwazi yini ukuhlangabezana nezidingo zedizayini yesakhiwo.

Ibanga lezinto ezibonakalayo: Izinto ezisetshenziswa kakhulu zemishayo ye-H yinsimbi yesakhiwo sekhabhoni (njengeQ235B, Q355B H Beamngezindinganiso zesiShayina, nomaI-A36, A572 H Beamezindinganisweni zaseMelika) kanye nensimbi ene-alloy high-strength. I-Q235B/A36 H I-Beam ifanele ukwakhiwa okuvamile (isb, izakhiwo zokuhlala, izimboni ezincane) ngenxa yokushisela kwayo okuhle kanye nezindleko eziphansi; I-Q355B/A572, enamandla okukhiqiza aphezulu (≥355MPa) namandla aqinile, ikhethwa kumaphrojekthi anzima njengamabhuloho, ama-workshops amakhulu, nama-cores wokwakha aphakeme, njengoba inganciphisa usayizi we-cross-section of the beam futhi yonge isikhala.

Ukucaciswa kweDimensional: Imishayo engu-H ichazwa ngobukhulu obuthathu: ubude (H), ububanzi (B), nokujiya kwewebhu (d). Isibonelo, i-H ebhalwe ukuthi "H300×150×6×8"kusho ukuthi inobude obungu-300mm, ububanzi obungu-150mm, ukujiya kwewebhu okungu-6mm, nogqinsi lwe-flange okungu-8mm. Imishayo yosayizi omncane H (H≤200mm) ivamise ukusetshenziselwa izakhiwo ezinjengamapulangwe aphansi kanye nezisekelo zokuhlukanisa; ezinosayizi omaphakathi (200mm＜H＜H) ophahleni lwama-main-400mm; amabhilidi amakhulu afakwa emafekthri ama-multi-ams; Imishayo engu-H (H≥400mm) ibalulekile ekuphakameni okuphezulu, amabhuloho amade, nezinkundla zemishini yezimboni.

Ukusebenza Komshini: Gxila ezinkomba ezifana namandla esivuno, amandla aqinile, nokuqina komthelela. Kumaphrojekthi asezindaweni ezibandayo (isb., enyakatho ye-China, e-Canada), imishayo engu-H kufanele iphumelele ukuhlolwa komthelela wezinga lokushisa eliphansi (okufana -40℃ nokuqina komthelela ≥34J) ukuze kugwenywe ukuphuka okufiphalayo ezimeni ezibandayo; ezindaweni zokuzamazama komhlaba, imikhiqizo ene-ductility enhle (i-elongation ≥20%) kufanele ikhethwe ukuze kuthuthukiswe ukumelana nokuzamazama komhlaba kwesakhiwo.

Sebenzisa Izimpawu Ezihlukile: Qondanisa "Izinzuzo Zomkhiqizo" Nezidingo Zephrojekthi

Uma kuqhathaniswa nezigaba zensimbi zendabuko ezifanaI-imishayokanye nezinsimbi zamashaneli, imishayo ye-H inezici zesakhiwo ezihlukile ezizenza zifaneleke izimo ezithile zokwakha-ukuqonda lezi zinzuzo kuyisihluthulelo sokukhethwa okuhlosiwe.

Ukusebenza Okuphezulu Kokuthwala Umthwalo: Isiqephu esiphambanayo esimise okwe-H semishayo ye-H sisakaza izinto ngokunengqondo kakhudlwana: ama-flange ajiyile (izingxenye ezivundlile ezingenhla nezingezansi) athwala isikhathi esiningi sokugoba, kuyilapho iwebhu encane (ingxenye emaphakathi eqondile) imelana namandla okugunda. Lo mklamo uvumela imishayo ye-H ukuthi ifinyelele umthamo ophezulu wokuthwala imithwalo ngokusetshenziswa okuncane kwensimbi-uma kuqhathaniswa ne-I-imishayo yesisindo esifanayo, imishayo ye-H inamandla okugoba aphezulu angu-15% -20%. Lesi sici sizenza zilungele amaphrojekthi aphishekela ukonga izindleko nezakhiwo ezingasindi, njengezakhiwo ezakhiwe ngaphambili kanye nokwakhiwa kwemojuli.

Ukuzinza Okuqinile Nokufakwa Okulula: I-symmetric H cross-section inciphisa ukuwohloka kwe-torsional ngesikhathi sokwakhiwa, okwenza imishayo ye-H iqine kakhulu uma isetshenziswa njengemishayo ethwala imithwalo eyinhloko. Ukwengeza, ama-flange awo ayisicaba kulula ukuwaxhuma nezinye izingxenye (isb, amabhawodi, amashisela) ngaphandle kokucubungula okuyinkimbinkimbi—lokhu kunciphisa isikhathi sokwakha endaweni ngo-30% uma kuqhathaniswa nezingxenye zensimbi ezingajwayelekile, okubalulekile kumaphrojekthi asheshayo afana nezakhiwo zezohwebo nengqalasizinda yezimo eziphuthumayo.

Ukugqwala Okuhle Nokumelana Nomlilo (ngokwelashwa): Imishayo ye-H engacutshungulwanga ijwayele ukugqwala, kodwa ngemva kokwelashwa okungaphezulu okufana ne-hot-dip galvanizing noma i-epoxy coating, ingamelana nokugqwala ezindaweni ezinomswakama noma ezisogwini (isb., amapulatifomu angasogwini, imigwaqo egudle ugu). Ezimweni zokushisa okuphezulu njengezindawo zokusebenzela zezimboni ezineziko, imishayo ye-H engashi (ehlanganiswe ngopende ovimba umlilo) ingagcina umthamo wokuthwala umthwalo ngaphezu kwemizuzu engu-120 uma kuba nomlilo, ihlangabezana nezindinganiso eziqinile zokuphepha emlilweni.

Izimo Zokusebenza Okuqondisiwe: Inketho Elungile

Amaphrojekthi wokwakha ahlukene anezidingo ezihlukene zemishayo ye-H. Kuphela ngokuvumelanisa izakhiwo zomkhiqizo nezimfuneko zesayithi lapho inani lazo lingakhuliswa. Okulandelayo yizimo zohlelo lokusebenza ezintathu ezijwayelekile nezinhlanganisela ezinconyiwe.

Izakhiwo Zokuhlala Nezohwebo Eziphakeme Eziphakeme: Ezakhiwo ezinezindaba ezingu-10-30, imishayo ye-H yegeji ephakathi eyenziwe ngensimbi ye-Q355B (H250×125×6×9 kuya ku-H350×175×7×11) iyanconywa. Amandla abo aphezulu asekela isisindo sezitezi eziningi, kuyilapho usayizi wazo ohlangene wonga isikhala sokuklama kwangaphakathi.

Amabhuloho kanye Nezakhiwo Zesikhathi Eside: Amabhuloho esikhathi eside (ahlanganisa amamitha angu-≥50) noma uphahla lwenkundla ludinga ama-H-beam amakhulu, aqine kakhulu (H400×200×8×13 noma ngaphezulu).

Izimboni Nezinqolobane: Izitshalo ezithwala kanzima (njengezitshalo ezikhiqiza izimoto) kanye nezindawo zokugcina izimpahla ezinkulu zidinga ama-H-beams akwazi ukusekela isisindo semishini noma ukupakisha impahla.
