Isingeniso kwi-U Channel kunye neC Channel
Ijelo le-U:
Intsimbi ene-U, kunye ne-cross-section efana neleta "U," ihambelana nomgangatho wesizwe we-GB / T 4697-2008 (owenziwe ngo-Aprili 2009). Isetyenziswa ngokuyintloko kwinkxaso yendlela yomgodi kunye nezicelo zenkxaso yetonela, kwaye iyimathiriyeli ephambili yokwenziwa kweenkxaso zetsimbi ezirhoxiswayo.
Ijelo le-C:
Intsimbi emile okwe-Cluhlobo lwentsimbi eyenziwe kukugoba okubandayo. I-cross-section yayo i-C-shaped, inamandla okugoba aphezulu kunye nokuxhathisa i-torsional. Isetyenziswa ngokubanzi kwiindawo zokwakha kunye nezoshishino.
Umahluko phakathi kwentsimbi emile okwe-U kunye nentsimbi eyi-C
1. Umahluko kwiimilo ezinqamlezileyo
Ijelo laseU: I-cross-section ikwimo yeleta yesiNgesi "U" kwaye ayinayo i-curling design. Iimilo ezinqamlezayo zihlulwe zibe ziindidi ezimbini: ukuma esinqeni (18U, 25U) kunye nokubeka indlebe (29U nangaphezulu). .
Ijelo leC: I-cross-section "C"-shaped, kunye nesakhiwo sangaphakathi se-curling emphethweni. Olu yilo luyenza ibe namandla okumelana nokugoba kwicala le-perpendicular kwiwebhu. .
2. Ukuthelekiswa kweempawu zoomatshini
(1): Iimpawu zokuthwala umthwalo
Intsimbi emise okwe-U: Ukunyanzeliswa koxinzelelo kwicala elihambelana nomda ongezantsi kubalaseleyo, kwaye uxinzelelo lunokufikelela ngaphezulu kwe-400MPa. Ifanelekile kwimiba yenkxaso yeemeko ezithwala imithwalo ethe nkqo ixesha elide. .
Intsimbi emile okwe-C: Amandla okugoba kwicala le-perpendicular kwiwebhu yi-30% -40% ephezulu kuneyentsimbi eyi-U, kwaye ifaneleke ngakumbi ukuthwala amaxesha okugoba njengemithwalo yomoya esecaleni. .
(2): Iimpawu zezinto eziphathekayo
Insimbi eyenziwe nge-U iveliswa ngokusebenzisa inkqubo yokutshisa, kunye nobukhulu ngokubanzi ukusuka kwi-17-40mm, ngokukodwa eyenziwe nge-20MnK yensimbi ephezulu.
Intsimbi emile okwe-C iqhelekile ukubanda, kunye nobukhulu bodonga olusuka kwi-1.6-3.0mm. Oku kuphucula ukusetyenziswa kwezinto nge-30% xa kuthelekiswa nentsimbi yentsimbi yendabuko.
3. IiNdawo zokuSebenza
Usetyenziso oluphambili lwentsimbi emile okwe-U:
Inkxaso esisiseko neyesibini kwiitonela zasemigodini (ibalelwa malunga nama-75%).
Izakhiwo zenkxaso kwiitonela zeentaba.
Amacandelo esiseko sokwakha iintsimbi zokugada kunye neesiding.
Usetyenziso oluqhelekileyo lwentsimbi emile okwe-C:
Iinkqubo zokunyuka zezityalo zamandla e-photovoltaic (ingakumbi izityalo zamandla ezibekwe phantsi komhlaba).
Iipurlins kunye neendonga zodonga kwizakhiwo zetsimbi.
Iindibano ze-Beam-column zezixhobo zoomatshini.
Ukuthelekiswa kweenzuzo zentsimbi e-U kunye ne-C-shaped steel
Izinto ezilungileyo ze-U-Shaped Steel
Umthamo oqinileyo wokuthwala umthwalo: I-U-shaped cross-sections inikezela ukugoba okuphezulu kunye nokumelana noxinzelelo, kubenza bafanelekele izicelo ezifuna imithwalo enzima, njengenkxaso ye-tunnel ye-mine kunye nee-weighbridges.
Ukuzinza okuphezulu: Izakhiwo zetsimbi ezi-U-shaped deformation kwaye azithinteki kakhulu ekunxibeni okubalulekileyo kunye nomonakalo kwixesha elide lokusetyenziswa, ukubonelela ngokhuseleko oluphezulu.
Ukucutshungulwa ngokufanelekileyo: Insimbi ene-U inokulungiswa ngokuguquguqukayo isebenzisa imingxuma eyenziwe ngaphambili, ivumela ukufakwa okuguquguqukayo kunye nohlengahlengiso, iyenze ilungele izicelo ezifuna ukulungiswa rhoqo, njengeenkqubo zokuxhoma i-photovoltaic yophahla.
Izinto eziluncedo zentsimbi emise okwe-C
Ukusebenza okugqwesileyo okuguquguqukayo: Isakhiwo sangaphakathi esigobileyo somphetho wentsimbi emise okwe-C sinika amandla akhethekileyo e-flexural perpendicular to web, okwenza ukuba ifanelekele izicelo ezinomoya ovuthuzayo okanye ezo zifuna ukumelana nomthwalo osecaleni (njengeenkqubo ze-photovoltaic kwimimandla yeentaba okanye kwiindawo eziselunxwemeni).
Uqhagamshelo olomeleleyo: I-flange kunye noyilo loqhagamshelo oludityanisiweyo lubonelela ngamandla okuthwala umthwalo ophuculweyo, okwenza ukuba lulungele izakhiwo ezintsonkothileyo okanye iziphanzi ezinkulu (ezifana neefektri ezinkulu kunye neebhulorho).
Ukungena komoya kunye nokuhanjiswa kokukhanya: Isithuba esibanzi phakathi kweeplanga siyenza ilungele izicelo ezifuna umoya okanye ukuhanjiswa kokukhanya (njengamaqonga kunye neepaseji).
