Nā ʻano onā puʻu pepa kila
Wahi a "Puʻu Pepa Kila Wela"(GB/T 20933-2014), ʻo ka paila pepa kila i ʻōwili wela ʻia he ʻekolu ʻano, ʻo nā ʻano kikoʻī a me ko lākou mau inoa code penei:Puʻu pepa kila ʻano U, inoa code: puʻu pepa kila ʻano PUZ, inoa code: puʻu pepa kila linear PZ, inoa code: PI Nānā: kahi ʻo P ka leka mua o ka puʻu pepa kila ma ka ʻōlelo Pelekania (Pile), a ʻo U, Z, a me I ke ʻano ʻokiʻoki o ka puʻu pepa kila.
No ka laʻana, ʻo ka paila pepa kila ʻano U i hoʻohana pinepine ʻia, ʻo PU-400X170X15.5, hiki ke hoʻomaopopo ʻia he 400mm ka laulā, 170mm ke kiʻekiʻe, 15.5mm ka mānoanoa.
puʻu pepa kila ʻano-z
Puʻu pepa kila ʻano U
No ke aha i hoʻohana pinepine ʻia ai ke ʻano U ʻaʻole ia he ʻano Z a pololei paha i ka ʻenekinia? ʻO ka ʻoiaʻiʻo, ua like like nā ʻano mechanical o ke ʻano U a me ke ʻano Z no hoʻokahi, akā ʻike ʻia ka pono o ka puʻu pepa kila ʻano U i ka hana hui ʻana o nā puʻu pepa kila ʻano U he nui.
Mai ke kiʻi ma luna, hiki ke ʻike ʻia he ʻoi aku ka nui o ke kūlou ʻana o ka paʻakikī no kēlā me kēia mika linear o ka puʻu pepa kila ʻano U ma mua o ka puʻu pepa kila ʻano U hoʻokahi (ua hoʻoneʻe nui ʻia ke kūlana axis kūlike) ma hope o ka nahu pū ʻia ʻana o ka puʻu pepa kila ʻano U.
2. Mea hoʻopili pepa kila
Ua hoʻopau ʻia ke kila kila Q345! Wahi a ke kūlana hou "Low Alloy High Strength Structural Steel" GB/T 1591-2018, mai Pepeluali 1, 2019, ua hoʻopau ʻia ke kila kila Q345 a ua hoʻololi ʻia i Q355, e like me ke kila kila S355 maʻamau o EU. ʻO Q355 kahi kila ikaika kiʻekiʻe haʻahaʻa maʻamau me ka ikaika hua o 355MPa.
