I-Prestressed steel wire yinto eguquguqukayo kwaye iyimfuneko kwishishini lokwakha.Yenziwe kwi-high-carbon steel high-carbon steel hot-rolled wire rods eziphathwa ngobushushu kwaye zisebenza ngokubanda, ezi ngcingo zenzelwe ngokukodwa ukuhlangabezana neemfuno ezifunekayo zokuqiniswa kwekhonkrithi.Ucingo lwensimbi lunomxholo wekhabhoni we-0.65% ukuya kwi-0.85%, umxholo wesulfure kunye ne-phosphorus ongaphantsi kwe-0.035%, kwaye unamandla amakhulu kunye nokuqina.
I-Prestressed steel wire yenze inkqubela phambili enkulu ukususela kwimveliso yayo yoshishino kunye nokusetyenziswa kwayo kwi-1920s.Namhlanje, iindidi zeemveliso ezifanelekileyo kwizicelo ezahlukeneyo kunye neempawu ezahlukeneyo zenziwe.Oku kuquka ucingo olutsalwa ngokubanda, ucingo olululekisiweyo, ucingo olupholileyo olusezantsi, ucingo lwezinki kunye nocingo lwamanqaku.Ezi mveliso, zidityaniswe nemisonto yentsimbi, ziye zaba zezona ntlobo zentsimbi zisetyenziswa kakhulu kwihlabathi.
Ukuya kuthi ga kuhlelo, ucingo olusezantsi lwe-PC lukhetho oludumileyo.Ukomelela kwayo okugqwesileyo kuyenza ilungele izicelo zoxinzelelo oluphezulu.Ukongezelela, ubukhulu bocingo lwensimbi buyi-2.64 mm, okwenza kube lula kwiiprojekthi ezahlukeneyo zokwakha.Ukongezelela, olu cingo lwekhonkrithi olugxininisiweyo luhambelana nemigangatho echazwe kwi-1084 SAEJ403, iqinisekisa umgangatho wayo kunye nokuthembeka.
Enye yezona zinto ziphawuleka kakhulu zocingo lwentsimbi olucinezelekileyo ngamandla awo akhethekileyo.Ngokubanzi, amandla okuqina kolu hlobo locingo lwentsimbi lungaphezulu kwe-1470MPa, ngokuthe ngcembe lutshintshela kwinqanaba lamandla eliphambili le-1670 ~ 1860MPa.Ngaphezu koko, ububanzi bocingo buye baguquka ngokuhamba kwexesha, ukusuka kwi-3 ukuya kwi-5 mm ukuya kuluhlu lwangoku lwe-5 ukuya kwi-7 mm.Lo mandla ongeziweyo kunye nedayamitha enkulu yenza ukuba ucingo olugxininiswe lunwenwe kakhulu kwaye lukwazi ukumelana nemithwalo emikhulu.
Ngenxa yeempawu zayo ezintle, ucingo lwentsimbi olugxininisiweyo lusetyenziswa ngokubanzi kwiindawo ezahlukeneyo zokwakha.Ngokuqhelekileyo isetyenziselwa ukuqinisa izakhiwo ezifana neebhulorho, izakhiwo kunye neendlela zikaloliwe ukuphucula umthamo wabo wokuthwala umthwalo kunye nokuthembeka kwesakhiwo ngokubanzi.Amacandelo oshishino kunye neziseko ezingundoqo athembele kakhulu kwi-prestressed steel wire ukuqinisekisa ixesha elide kunye nokhuseleko lweeprojekthi zabo.
Isishwankathelo, uphuhliso lwe-prestressed steel wire luguqule ishishini lokwakha.Ukudityaniswa komgangatho ophezulu wekhabhoni yensimbi kunye nobuchule obuphezulu bomatshini buphumela kuluhlu lweemveliso ezifanelekileyo kwiinkqubo ezahlukeneyo.Ngoluhlu olubanzi lokuhlula kunye nobukhulu okukhethwa kukho, kunye namandla abalaseleyo okuqina kunye nokusetyenziswa okuninzi, ucingo lwentsimbi olugxininisiweyo luhlala luyingxenye ebalulekileyo kulwakhiwo lwangoku.
Isicelo
Njengoko iChina imveliso yesinyithi ekhokelayo kumashishini, urhwebo lwesizwe lwentsimbi kunye nezixhobo "Ikhulu leshishini elithembekileyo lokholo", amashishini entsimbi yaseTshayina, "amashishini abucala ali-100 aphezulu eShanghai". ) ithatha i" Integrity, Practicality, Innovation, Win-Win " njengomgaqo wayo wodwa wokusebenza, ihlala iphikelela ekubekeni imfuno yomthengi kwindawo yokuqala.
