H-beam I-beam Hot Rolled Iron Carbon Steel Dip galvanized

ʻO ke kila ʻāpana H he ʻano o ka ʻāpana waiwai a me ka ʻāpana kiʻekiʻe me ka hoʻolaha ʻana o ka ʻāpana cross-sectional a ʻoi aku ka maikaʻi o ka lākiō ikaika-i-kaumaha. Ua kapa ʻia ʻo ia no ka mea ua like kona ʻāpana me ka leka Pelekane "H". No ka mea ua hoʻonohonoho ʻia nā ʻāpana like ʻole o ke kila H-like ma nā kihi ʻākau, ʻo ke kila H-like nā mea maikaʻi o ke kūpaʻa kūlou ikaika, ka hana maʻalahi, ka mālama ʻana i ke kumukūʻai a me ke kaumaha o ke ʻano māmā ma nā ʻaoʻao āpau, a ua hoʻohana nui ʻia. ʻOi aku ka mānoanoa o ka pūnaewele o ka H-beam ma mua o ka I-beam maʻamau me ke kiʻekiʻe like o ka pūnaewele, a ʻoi aku ka laulā o ka flange ma mua o ka I-beam maʻamau me ke kiʻekiʻe like o ka pūnaewele. no laila ua kapa ʻia ʻo ia ʻo ka I-beam ākea ākea. Hoʻoholo ʻia e ke ʻano, ʻoi aku ka maikaʻi o ka modulus pauku, ka manawa o ka inertia a me ka ikaika like o nā kaola H ma mua o nā I-beam maʻamau o ke kaumaha hoʻokahi. Hoʻohana ʻia i loko o nā hale metala me nā koi like ʻole, inā paha ia e kūlou ana i ka manawa kūlou, ka haʻahaʻa kaomi, a i ʻole ka ukana eccentric, hōʻike ia i kāna hana ʻoi aku ka maikaʻi. Ke hoʻohālikelike ʻia me ka I-beam maʻamau, hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hiki ke halihali a mālama i ka metala e 10% -40%. ʻO ke kila H-like me nā flanges ākea, nā pūnaewele lahilahi, nā kikoʻī he nui, a me ka hoʻohana maʻalahi. Hiki iā ia ke mālama i ka 15% a i ka 20% o ka metala ke hoʻohana ʻia i nā ʻano hana truss like ʻole. Ma muli o ka like o nā flanges i loko a me waho, a aia nā ʻaoʻao i nā kihi ʻākau, maʻalahi ka hui ʻana a hoʻohui i nā ʻāpana like ʻole, hiki ke mālama i kahi 25% o ka hana welding a me ka riveting, hiki ke hoʻolōʻihi i ka wikiwiki o ke kūkulu ʻana. papahana a hoʻopōkole i ka manawa kūkulu.
