Gawo la Hollow
Kufotokozera Kwachidule:
Square hollow section (SHS) imatanthawuza mtundu wa chitsulo chomwe chili ndi masikweya apakati ndipo mkati mwake mulibe. Amagwiritsidwa ntchito kwambiri m'mafakitale omanga ndi kupanga zinthu zosiyanasiyana chifukwa cha kapangidwe kake komanso kukongola kwake.
Gawo Lamabowo:
Gawo lopanda kanthu limatanthawuza mbiri yachitsulo yokhala ndi dzenje ndipo imagwiritsidwa ntchito mosiyanasiyana pamapangidwe ndi uinjiniya. Mawu oti "gawo lopanda kanthu" ndi gulu lalikulu lomwe limaphatikiza mawonekedwe osiyanasiyana, kuphatikiza masikweya, amakona anayi, ozungulira, ndi mawonekedwe ena. Zigawozi zapangidwa kuti zipereke mphamvu zamapangidwe ndi kukhazikika pamene nthawi zambiri zimachepetsera kulemera.Zigawo zopanda kanthu nthawi zambiri zimapangidwa kuchokera kuzitsulo monga zitsulo, aluminiyamu, kapena ma alloys ena.Kusankha kwa zinthu kumadalira zinthu monga mphamvu zofunikira, kukana kwa dzimbiri, ndi zomwe zimafunidwa. ntchito.

Gawo la Square Hollow (SHS):
A Square Hollow Section (SHS) ndi mbiri yachitsulo yokhala ndi magawo apakati komanso mkati mwake. Imagwiritsidwa ntchito kwambiri pomanga ndi kupanga, SHS imapereka maubwino monga mphamvu zolimbitsa thupi, kusinthasintha kwamapangidwe, komanso kupanga kosavuta. Maonekedwe ake oyera a geometric ndi kukula kwake kosiyanasiyana kumapangitsa kuti ikhale yoyenera pomanga mafelemu, zida zothandizira, makina, ndi ntchito zina. SHS nthawi zambiri imapangidwa kuchokera kuzinthu monga chitsulo kapena aluminiyamu, imatsatira miyezo yamakampani, ndipo imatha kuthandizidwa kuti isawonongeke.
