Chitsulo

Mawonekedwe a Structural Steel pa Sitima

Chitsulo chomangira zombo nthawi zambiri chimatanthawuza zitsulo zomangira zitsulo, zomwe zimatanthawuza chitsulo chomwe chimagwiritsidwa ntchito popanga zomangira zomwe zimapangidwa motsatira zomwe zimafunikira pakumanga kwa gulu la anthu. Nthawi zambiri amalamulidwa, kukonzedwa ndikugulitsidwa ngati chitsulo chapadera. Chombo chimodzi chimaphatikizapo mbale za sitima, zitsulo zooneka ngati zitsulo, ndi zina zotero.

Pakalipano, makampani akuluakulu angapo azitsulo m'dziko langa amapanga, ndipo amatha kupanga zitsulo zam'madzi malinga ndi zosowa za wosuta m'mayiko osiyanasiyana, monga United States, Norway, Japan, Germany, France, etc.

(1) Zosiyanasiyana

Chitsulo cha zomangamanga cha ma hull chimagawidwa m'magulu amphamvu molingana ndi mfundo zawo zochepa zokolola: mphamvu zambiri zopangira zitsulo ndi zitsulo zamphamvu kwambiri.

Chitsulo champhamvu chodziwika bwino ndi China Classification Society chimagawidwa m'magulu anayi: A, B, D, ndi E; Chitsulo champhamvu champhamvu chofotokozedwa ndi China Classification Society chimagawidwa m'magulu atatu amphamvu ndi magawo anayi apamwamba:

A32 A36 A40
D32 D36 D40
E32 E36 E40
F32 F36 F40

(2) Makina amakina ndi kapangidwe kake

Zimango katundu ndi mankhwala zikuchokera ambiri mphamvu hull structural zitsulo

(3) Kusamala popereka ndi kuvomereza zinthu zachitsulo zam'madzi:

1. Ndemanga za satifiketi yabwino:

Fakitale yachitsulo iyenera kupereka katunduyo malinga ndi zomwe wogwiritsa ntchito akufuna komanso zomwe adagwirizana mu mgwirizano ndikupereka chiphaso choyambirira cha khalidwe. Satifiketi iyenera kukhala ndi izi:

(1) Zofuna zatsatanetsatane;

(2) Nambala ya mbiri yabwino ndi nambala ya satifiketi;

(3) Nambala ya ng'anjo yamoto, mulingo waukadaulo;

(4) Chemical zikuchokera ndi katundu makina;

(5) Chikalata chovomerezeka kuchokera ku gulu lamagulu ndi siginecha ya wofufuza.

2. Ndemanga yakuthupi:

Popereka zitsulo zam'madzi, chinthu chenichenicho chiyenera kukhala ndi chizindikiro cha wopanga, ndi zina zotero.

(1) Chizindikiro cha chivomerezo cha gulu;

(2) Gwiritsani ntchito penti kuti muyimire kapena kuyika chizindikirocho, kuphatikiza magawo aukadaulo monga: nambala ya batchi ya ng'anjo, giredi yokhazikika, kutalika ndi kukula kwake, ndi zina zambiri;

(3) Maonekedwe ndi osalala komanso osalala, opanda chilema.
