Ub 914*419*388 UC 356*406*393 Hea Heb Hem 150 Wotentha Wokulungidwa Welded H Mitsinje yokhala ndi Mtengo Wabwino Kwambiri Wopanga China

Miyendo ya HEA, HEB, ndi HEM ili ndi ntchito zosiyanasiyana m'mafakitale omanga ndi zomangamanga. Zina zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

1. Mtsinje wa HEA (wopepuka H-beam): Oyenera ntchito zochepa komanso zopepuka.

Ubwino waukulu ndi kulemera kopepuka, kugwiritsa ntchito zinthu zambiri, komanso kukhazikitsa kosavuta. Zochita zake zamakina zimakwaniritsa zofunikira zonyamula katundu, ndikuchotsa kufunikira konyamula katundu wambiri. Ntchito zake zazikulu ndi:

Nyumba zachitukuko: matabwa achiwiri, mazenera a khoma, ndi mafelemu a khonde m'nyumba zogonamo / zipinda;

Mafakitale ang'onoang'ono: zida zothandizira mafakitale opepuka (monga matabwa achiwiri ndi mafelemu okonza njira), ndi mizati yosungiramo katundu;

Mapulogalamu osanyamula katundu kapena otsika: mazenera a denga m'malo ogulitsa (malo ogulitsira, malo owonetserako), ndi mafelemu osakhalitsa opepuka.

2. HEB Beam (Medium H-Beam): Yoyenera pazambiri zapakatikati

Ubwino waukulu wa matabwa a HEB ndi zinthu zamakina oyenerera (kupindika pang'ono ndi kukana kukameta ubweya), kusinthasintha kwamphamvu, komanso kukwera mtengo. Amagona pakati pa mapangidwe opepuka a matabwa a HEA ndi mapangidwe olemetsa a matabwa a HEM. Ndiwo mtundu womwe umagwiritsidwa ntchito kwambiri pakumanga ndi zomangamanga, zomwe zimagwiritsidwa ntchito poyambira:

Nyumba zamafakitale ndi zamalonda: mizati/mipingo ikuluikulu ya mafakitale apakati, mafelemu onyamula katundu a nyumba za maofesi ansanjika zambiri, ndi mizati yonyamulira katundu ya masitolo akuluakulu ndi nyumba zosungiramo katundu;

Zomangamanga zazing'ono ndi zazing'ono: Mitanda ikuluikulu ya milatho ya misewu yakumidzi, nyumba zonyamula katundu zodutsa anthu oyenda pansi m'tauni, ndi zothandizira zosungirako madzi ang'onoang'ono (monga ngalande zamadzi);

Zida ndi mamangidwe: Mafelemu oyambira amakina apakati (monga zothandizira zida zamakina), mafelemu akulu a canopies achitsulo, ndi mizati yonyamula katundu pamalo oimika magalimoto.

3. HEM mtengo (Heavy Duty H-Beam): Yoyenera kunyamula katundu wambiri komanso malo ogwirira ntchito kwambiri

Ubwino waukulu wa matabwa a HEM ndi ma webs/flanges wandiweyani, nthawi yayikulu yolumikizirana ndi inertia, komanso kunyamula katundu wambiri. Amatha kupirira mphindi zazikulu zopindika, mphamvu zazikulu za axial, ndi katundu wovuta (monga kugunda ndi kugwedezeka). Amagwiritsidwa ntchito makamaka mu:

Mafakitale olemera kwambiri: Mitanda / mizati yayikulu m'mafakitale olemera (monga mabwalo a zombo ndi zitsulo zamagetsi), mafelemu othandizira ng'anjo zophulitsa zitsulo, ndi maziko a zida zolemera (ma cranes ndi mphero);

Zomangamanga zazikulu: mizati ikuluikulu ya milatho ya misewu yayikulu/njanji, mabeya a milatho yodutsa mitsinje, ndi mizati yolumikizira mizati ya misewu ikuluikulu yokwezeka m’tauni;

Ntchito zapadera zopatsirana kwambiri: Chigawo chapansi chonyamula katundu cha nsanja zotumizira, mizati yothandizira matanki akuluakulu osungira (ma tanki amafuta osakhwima ndi matanki amankhwala), komanso zothandizira mayendedwe onyamula katundu wolemera m'migodi yapansi panthaka.
