ʻO ke kaula kila prestressed he mea maʻalahi a koʻikoʻi i ka ʻoihana kūkulu. Hana ʻia mai ke kila kila kila kiʻekiʻe kiʻekiʻe i hoʻopaʻa ʻia i ka wela a me ka hana anu, ua hoʻolālā kūikawā ʻia kēia mau uea e hoʻokō i nā koi koi o ka hoʻoikaika ʻana i ke kaila prestressed. ʻO ka uea kila he carbon content o 0.65% a 0.85%, he sulfur a me ka phosphorus ma lalo o 0.035%, a he ikaika maikaʻi loa a me ka lōʻihi.
Ua holomua nui ka uea kila prestressed mai kona hana ʻana a me ka noi ʻana i nā makahiki 1920. I kēia lā, ua hoʻokumu ʻia nā ʻano huahana like ʻole no nā noi like ʻole a me nā ʻano like ʻole. He uea huki anu, uea pololei, uea hoomaha haahaa, uea galvanized a me uea scored. ʻO kēia mau huahana, i hui pū ʻia me nā kaula kila prestressed, ua lilo i mau ʻano kila prestressed i hoʻohana nui ʻia ma ka honua.
Ma kahi o ka hoʻohālikelike ʻana, ʻo ka uea PC serrated haʻahaʻa haʻahaʻa kahi koho kaulana. ʻO kona ikaika tensile maikaʻi e kūpono ia no nā noi koʻikoʻi kiʻekiʻe. Eia kekahi, ʻo ka mānoanoa o ke kaula kila he 2.64 mm, kūpono ia no nā ʻano hana kūkulu. Eia kekahi, ua hoʻokō kēia uea kaʻa prestressed i nā kūlana i kuhikuhi ʻia ma 1084 SAEJ403, e hōʻoiaʻiʻo ana i kona ʻano a me ka hilinaʻi.
ʻO kekahi o nā hiʻohiʻona kaulana loa o ka uea kila prestressed ʻo ia kona ikaika tensile. ʻO ka maʻamau, ʻoi aku ka ikaika tensile o kēia ʻano uea kila ma luna o 1470MPa, e neʻe mālie ana i ka pae ikaika nui o 1670 ~ 1860MPa. Eia kekahi, ua ulu aʻe ke anawaena o ka uea i ka manawa, mai 3 a 5 mm a hiki i kēia manawa o 5 a 7 mm. ʻO kēia hoʻonui ikaika a me ke anawaena ʻoi aku ka mea e hiki ai i ka uea prestressed ke kūpaʻa i nā ukana nui.
Ma muli o kāna mau waiwai maikaʻi, ua hoʻohana nui ʻia ka uea kila prestressed i nā kahua kūkulu like ʻole. Hoʻohana maʻamau ia e hoʻoikaika i nā hale e like me nā alahaka, nā hale a me nā ala kaʻaahi no ka hoʻomaikaʻi ʻana i ko lākou hiki ke halihali i ka ukana a me ka paʻa o ke kūkulu ʻana. Ke hilinaʻi nui nei nā ʻoihana ʻoihana a me nā ʻoihana i ka uea kila prestressed e hōʻoia i ka lōʻihi a me ka palekana o kā lākou mau papahana.
I ka hōʻuluʻulu ʻana, ua hoʻololi ka hoʻomohala ʻana o ka uea kila prestressed i ka ʻoihana kūkulu. ʻO ka hui pū ʻana o ke kila kila kiʻekiʻe kiʻekiʻe a me nā ʻenehana mīkini kiʻekiʻe e loaʻa i nā ʻano huahana kūpono no nā ʻano noi. Me ka laulā o ka hoʻokaʻawale ʻana a me nā koho nui, a me ka ikaika tensile maikaʻi loa a me nā hoʻohana he nui, ʻo ka uea kila prestressed ka mea nui i ka hana hou.
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.
