ʻO ke kaula kila prestressed he uea kila kiʻekiʻe kiʻekiʻe i hana ʻia e ka mālama wela a me ka hana anu.Hoʻolālā kūikawā ʻia ia e hoʻokō i nā koi o ka hoʻoikaika ʻana i ka prestressed concrete.ʻO ka uea kila he kalapona ka 0.65% a hiki i ka 0.85% a me ka sulfur a me ka phosphorus ma lalo o 0.035%, e hōʻoia ana i ka ikaika tensile maikaʻi a me ka lōʻihi.Mai kona hana ʻana a me ka noi ʻana i nā makahiki 1920, ua ulu nui ka uea kila prestressed a i kēia manawa ua hoʻopili ʻia nā ʻano huahana i kūpono no nā noi like ʻole.
He ikaika maikaʻi loa ka uea kila prestressed, me ka ikaika tensile haʻahaʻa o 1470MPa.Ua ulu ka pae ikaika i nā makahiki, e hoʻololi ana mai ka 1470MPa mua a me 1570MPa i ka 1670-1860MPa i kēia manawa.Ua loli pū ke anawaena o ke kaula kila, mai 3-5 mm a i 5-7 mm.Hāʻawi kēia ʻano kikoʻī i ka maʻalahi a me nā koho no nā ʻano hana kūkulu, e ʻae ana i nā ʻenekini e koho i ka ikaika a me ka nui kūpono no kā lākou noi kikoʻī.
Hāʻawi ka mākeke uea kila prestressed i nā huahana like ʻole me nā ʻano like ʻole e hoʻokō i nā pono like ʻole.ʻO kēia mau mea e pili ana i ka uea kila huki anu, ka uea kila hoʻopololei a me ka huhū, ka uea haʻahaʻa hoʻomaha haʻahaʻa, ka uea kila galvanized, ka uea kila kila, a me nā mea ʻē aʻe. .Hāʻawi kēia hui i nā mea hoʻohana e ʻike i ka hoʻokūkū kūpono no kā lākou mau koi kikoʻī, e hōʻoiaʻiʻo ana i ka ʻoi aku ka maikaʻi a me ka hana.
ʻO kekahi o nā hiʻohiʻona nui o ka uea kila prestressed ʻo ia kona ikaika tensile kiʻekiʻe.ʻO kēia ikaika, i hui pū ʻia me nā mana koʻikoʻi i ke kalapona, ka sulfur a me ka phosphorus content, e hōʻoia i ka hana pono a me ka lōʻihi o ka hoʻoikaika ʻana i ke koʻo prestressed.ʻO ka hiki o ka uwea ke mālama i ka wela a me ka hana anu e hoʻonui hou i kona mau waiwai mechanical, e pale ai i ka corrosion, ka luhi a me ke kaumaha.Ua hoʻolālā ʻia ka uea kila prestressed e kū i ke kaomi ikaika, e hāʻawi ana i ka paʻa mau loa a me ka ikaika i ka hale.
Hoʻohana nui ʻia nā uea kila pretressed i ka ʻoihana kūkulu.Hoʻohana nui ʻia ia i loko o nā hale paʻa prestressed e like me nā alahaka, nā hale kiʻekiʻe, nā tunnels, nā ala kaʻaahi, a hiki i ka ʻoihana precast concrete.ʻO ka ikaika a me ka hilinaʻi o nā uea kila he mea koʻikoʻi i ka hoʻoikaika ʻana i kēia mau hale, e hōʻoiaʻiʻo ana lākou e pale aku i nā ikaika o waho e like me ke olai a me nā ukana kaumaha.ʻO kāna hana kiʻekiʻe, palekana a me ka lōʻihi i hoʻohālikelike ʻia me nā mea hoʻoikaika kuʻuna maʻamau, ʻo ia ke koho mua no ke koi ʻana i nā hana kūkulu a puni ka honua.
I ka hopena, prestressed uea kila he versatile a hilinaʻi mea i hoʻohana nui 'ia i loko o ka hale hana.Me kāna mau hiʻohiʻona kūʻokoʻa, ka laulā huahana ākea a me ka hoʻokō pono ʻana i nā kikoʻī, hāʻawi ia i ka ikaika a me ka lōʻihi e pono ai no ka hoʻohālikelike ʻana i nā noi prestressed concrete.Inā he alahaka, hale a hale ʻē aʻe paha, hāʻawi ka uea kila prestressed i nā ʻenekinia a me nā limahana hana me kahi hopena hilinaʻi no ka hana ʻana i nā hale paʻa a lōʻihi.
Palapala noi
ʻOiai ʻo Kina ʻoihana metala ʻoihana alakaʻi i nā ʻoihana, ʻo ke kālepa kila aupuni a me ka logistic "Hundred good faith enterprise", China steel trade enterprises, "Top 100 private enterprises in Shanghai". ) lawe i ka "Integrity, Practicality, Innovation, Win-Win" ma ke ʻano o kāna kumu hana hoʻokahi, hoʻomau mau i ka waiho ʻana i ka koi o ka mea kūʻai aku ma kahi mua.
