Isingeniso se-U Channel kanye ne-C Channel
Isiteshi se-U:
Insimbi emise okwe-U, enesigaba esiphambanayo esifana nohlamvu "U," ithobelana nezinga likazwelonke le-GB/T 4697-2008 (liqaliswe ngo-April 2009). Isetshenziswa ngokuyinhloko ekusekeleni umgwaqo wezimayini nasezinhlelweni zokusekela umhubhe, futhi iyimpahla ebalulekile ekwenzeni izisekelo zensimbi ezihoxiswayo.
Isiteshi se-C:
Insimbi emise okwe-Cwuhlobo lwensimbi olwakhiwe ukugoba okubandayo. I-cross-section yayo imise okwe-C, inamandla okugoba aphezulu kanye nokumelana ne-torsional. Isetshenziswa kabanzi emikhakheni yezokwakha nezimboni.
Umehluko phakathi kwensimbi emise okwe-U nensimbi emise okuka-C
1. Umehluko kumajamo ahlukene
Isiteshi se-U: I-cross-section isesimweni sohlamvu lwesiNgisi oluthi "U" futhi alunawo umklamo wokugoqa. Umumo we-cross-sectional uhlukaniswe waba izinhlobo ezimbili: ukuma okhalweni (18U, 25U) kanye nokuma kwendlebe (29U nangaphezulu). .
Isiteshi C: I-cross-section "C" -shaped, enesakhiwo sangaphakathi sokugoqa emaphethelweni. Lo mklamo uwenza ibe nokugoba okuqinile kokumelana ne-perpendicular kuwebhu. .
2. Ukuqhathaniswa kwezakhiwo zemishini
(1): Izici zokuthwala umthwalo
Insimbi emise okwe-U: Ukumelana okucindezelwayo ohlangothini oluhambisana nonqenqema olungezansi kuvelele, futhi ingcindezi ingafinyelela ngaphezu kuka-400MPa. Ilungele izimo zokusekela imayini ezithwala imithwalo eqondile isikhathi eside. .
Insimbi emise okwe-C: Amandla okugoba aqonde kuwebhu aphakeme ngo-30% -40% kunawensimbi emise okwe-U, futhi afaneleka kakhulu ukuthwala izikhathi zokugoba njengemithwalo yomoya ehlangothini. .
(2): Izinto ezibonakalayo
Insimbi emise okwe-U ikhiqizwa kusetshenziswa inqubo yokugoqeka okushisayo, enobukhulu obujwayelekile obusuka ku-17-40mm, ngokuyinhloko eyenziwe ngensimbi enamandla angu-20MnK.
Insimbi emise okwe-C ivamise ukubanda, enogqinsi olusuka ku-1.6-3.0mm. Lokhu kuthuthukisa ukusetshenziswa kwezinto ngo-30% uma kuqhathaniswa nensimbi yesiteshi esivamile.
3. Izindawo Zokufaka Isicelo
Ukusetshenziswa Okuyinhloko Kwensimbi Emise Oku-U:
Ukwesekwa okuyisisekelo nokwesibili emiseleni yezimayini (ibalwa cishe ngama-75%).
Izakhiwo zokusekela zemigudu yezintaba.
Izingxenye zesisekelo zokwakha ama- guardrails nama-siding.
Ukusetshenziswa Okuvamile kwensimbi emise okwe-C:
Amasistimu okukhweza ezitshalo zamandla e-photovoltaic (ikakhulukazi izitshalo zamandla abekwe phansi).
Ama-purlins nemishayo yodonga ezakhiweni zensimbi.
Imihlangano ye-Beam-column yemishini yemishini.
Ukuqhathanisa izinzuzo zensimbi emise oku-U kanye nensimbi emise okwe-C
Izinzuzo ze-U-Shaped Steel
Amandla okuthwala umthwalo oqinile
Ukuzinza okuphezulu: Izakhiwo zensimbi ezimise okwe-U zimelana nokuguquguquka futhi azingenwa kalula ukuguga nokulimala isikhathi eside zisetshenziswa, zinikeza ukuphepha okuphakeme.
Ukucubungula okungenasidingo
Izinzuzo zensimbi emise okwe-C
Ukusebenza okuhle kakhulu okuguquguqukayo
Ukuxhuma okuqinile: I-flange ne-bolted yokuxhuma idizayini inikeza amandla okuthwala umthwalo athuthukisiwe, okwenza ifaneleke izakhiwo eziyinkimbinkimbi noma ama-spans amakhulu (njengamafektri amakhulu namabhuloho).
Ukungena komoya kanye nokudluliswa kokukhanya: Isikhala esibanzi phakathi kwemishayo siyenza ifanelekele izinhlelo zokusebenza ezidinga umoya noma ukudluliswa kokukhanya (njengamapulatifomu namaphasishi).
