He moʻolelo lōʻihi ka uea kila prestressed, a hiki ke huli ʻia kāna hana ʻoihana a me ka noi ʻana i nā makahiki 1920.Ua loaʻa i ka hoʻomohala koʻikoʻi i nā makahiki, ka hopena o nā huahana me nā waiwai like ʻole i kūpono no nā noi like ʻole.ʻO kēia nā uea huki anu, uea hoʻopololei a hoʻohaʻahaʻa, uea hoʻomaha haʻahaʻa, uea galvanized a me uea scored.ʻO kēia mau huahana a me nā kaula kila prestressed i hana ʻia mai ia mau mea i lilo i mau ʻano kila prestressed i hoʻohana nui ʻia i ʻike ʻia ma ka honua.
1) Kūlana: ASTM A-421
2) Nui: 3mm-12mm
3) Ka ikaika tensile: ≥1700Mpa
4) Coil kaumaha: 800-1500kg
5) Hoʻopaʻa ʻana: Pūʻulu Kūʻai
12.7mm uea kila prestressed he kiʻekiʻe kiʻekiʻe kiʻekiʻe-carbon kila uea kūikawā i hoʻolālā ʻia no ka hoʻokō ʻana i nā koi hoʻoikaika ʻana o ke kaila prestressed.Hana ʻia ia mai ke kila kalapona kiʻekiʻe i ʻōwili ʻia i ka uea koʻokoʻo i mālama ʻia i ka wela a me ke anuanu e loaʻa ai nā waiwai i makemake ʻia.ʻO ka maʻiʻo kalapona o kēia ʻano uea kila he 0.65% a 0.85%, a he haʻahaʻa ka sulfur a me ka phosphorus ma lalo o 0.035%.
ʻO ka ikaika tensile o ka uea kila ma luna o 1470MPa, a ua loli mālie ka māka ikaika mai ka 1470MPa a me 1570MPa i ka 1670 ~ 1860MPa.Ma ke ʻano o ke anawaena, ua hoʻomohala ʻia ka uea kila mai ka 3mm a hiki i ka laulā o kēia manawa o 5 a 7mm.
Mai kahi helu helu o ka nānā ʻana, 12.7mm prestressed kila uea nona ka kiʻekiʻe prestressed wili kila.Hoʻonohonoho pono ʻia ia e hoʻokō i nā koi o ka hoʻoikaika ʻana i ka prestressed concrete, e hāʻawi ana i ka ikaika a me ke kūpaʻa i ke kūkulu ʻana i nā papahana e hoʻohana ana.
Ke nānā nei i nā kikoʻī, ʻo ka 12.7mm prestressed steel wire he carbon content o 0.65% a 0.85%, e hōʻoiaʻiʻo ana i ka hana e pono ai no kahi mea ikaika a paʻa.He haʻahaʻa haʻahaʻa ka sulfur a me ka phosphorus, e hoʻonui hou i kāna hana.ʻOi aku ka ikaika o ka tensile o ke kaula ma mua o 1470MPa, a ʻo ke anawaena ma ka laulā o 5 a 7mm.
Hoʻohana nui ʻia ka uea kila prestressed 12.7mm i nā ʻano hana hana ma muli o kona ikaika tensile kiʻekiʻe a me ka hana maikaʻi loa.Hoʻohana nui ʻia ia i nā hale paʻa prestressed e hāʻawi i ka hoʻoikaika a me ke kūpaʻa.Inā hoʻohana ʻia i loko o nā alahaka, nā hale a i ʻole nā hana ʻoihana ʻē aʻe, ʻo kēia uea kila e hōʻoia i ka hoʻoikaika a me ka hana lōʻihi o nā hale e kākoʻo ai.ʻO kāna versatility a me ka hilinaʻi e lilo ia i ʻāpana koʻikoʻi o ka hoʻolālā hou.
I ka hōʻuluʻulu ʻana, ʻo 12.7mm prestressed uea kila he huahana kiʻekiʻe e hoʻokō i nā koi hoʻoikaika o ke konikō prestressed.ʻO kona ikaika kiʻekiʻe, haʻahaʻa sulfur a me ka phosphorus, a me nā kikoʻī like ʻole e kūpono ia no nā ʻano hana kūkulu.Me kona moʻolelo lōʻihi a me kaʻike honua, ua lilo kēia uea kila i mea nui o kaʻoihana kūkulu, e hōʻoia ana i ka lōʻihi a me ka paʻa o nā hale ma ka honua holoʻokoʻa.
