Steel Space Frame Indasitiri 90m Span Coal Yard Project
Kuiswa kweSpace Frame Architecture:
Iyi purojekiti ndeye arched space frame / kureba ndeye 49 metres / yakazara kureba 633 metres / yakazara span 76.3 metres.
Iyo purojekiti inotora simbi nzvimbo furemu, fomu inotsigira ndiyo yepasi chord inotsigira, bhaudhi bhora rakabatana, uye kaviri-layer positive quadrangular pyramid plane grid.Iyo grid furemu inotsigirwa pamakoni ekongiri kumativi ese, uye zvitsigiso zvakasungirirwa nemisoro yembiru yekongiri mbiru.Iwo emagetsi emagetsi uye waya dzinoshandiswa pakushongedza dzinofanirwa kusangana nezvinodiwa zvezvino nyika zviyero.Iyo welding pakati peQ235B simbi inotora E43 akatevedzana maelectrodes, uye welding pakati peQ345B masimbi anotora E50 akatevedzana maelectrodes.
Iyo simbi nzvimbo furemu inoverengerwa uye yakagadzirwa neMST2020 software.
Pamusoro pekuzadzisa zvinodikanwa zvekodhi yenyika, simbi inoshandiswa muchirongwa ichi inofanirawo kuita zvinotevera zvinodiwa:
a) Chiyero chechiyero chakayerwa chekusimba kwegoho resimbi kune kuyerwa kukosha kwesimba rekusimba harifanirwe kunge rakakura kupfuura 0.85;
b) Simbi inofanira kuva nematanho ezvibereko zvakajeka, uye elongation inofanira kuva yakakura kudarika 20%;
c) Iyo simbi inofanirwa kuve yakanaka weldability uye inokwanisa kukanganisa kuoma;
Iyo simbi nzvimbo dhizaini dhizaini inotora 3D3S (vhezheni 14.0) software dhizaini yepombi chimiro chekombuta-inobatsira dhizaini uye yekugadzira sisitimu yekuita ongororo yesimba remukati renhengo uye otomatiki dhizaini yekushushikana kwakazara pamicrocomputer, uye iyo yega-. uremu huremu hwesimbi nzvimbo furemu inoiswa otomatiki mukuongorora kwesimba remukati.
Iyo yakaverengerwa kureba kwetsvimbo ndeye L0 = L, uye slenderness chiyero chekiyi tsvimbo inosungirira tsvimbo ≤ 200 uye compression tsvimbo ≤ 150. Chiyero che slenderness yemamwe matanda ndeye tie tsvimbo ≤ 250, kumanikidza tsvimbo ≤ 180.
