PC lashukumisa (Aluminium) Strand
Lo mkhiqizo usetshenziselwa ukuhlala izintambo, izintambo ezinkulu kanye nezinhlelo zokubambelela zezintambo zekhebula lebhuloho, izintambo zangaphandle zezinsimbi zebhuloho le-arch nezinye izakhiwo ezigxiliwe ezingathinti ngqo nodaka lukakhonkolo. sihlanganyele ekwakhiweni kwamabhuloho amaningi amakhulu ahlala ngentambo eChina. Ububanzi balo mkhiqizo bungu-12.70mm, 15.20mm, 15.70mm, 17.8mm futhi kuyindawo yokuphumula ephansi engaphambi kwengcindezi. Ucingo lwensimbi oluhlanganisiwe luye lwadonselwa futhi lwaqiniswa ukwelashwa kokushisa, lwabe selwenziwa phakathi nendawo ukuze lukhiqizwe ngomucu (i-aluminium). I-strand ayinaso isibopho, futhi ngeke ikhululeke ngemuva kokusika. Ukumbozwa kwendawo kufana futhi kuyaqhubeka, futhi ukuqina kuhle. Izici zomshini zihlangabezana nezidingo ze-ASTMA416, prEN10138, NFA35-035 namanye amazinga aphesheya. I-strand inobude bokulala obufanayo, okuyizikhathi eziyi-12-16 zobubanzi bokuzisholo. Ubuningi bokumboza kocingo olulodwa ngu-190 ~ 350g / m2. Okuqukethwe kwe-aluminium kwe-zinc-aluminium alloy steel strand enamathela akuyona ngaphansi kuka-4.2%. Ukunamathela kokumboza kunamandla, futhi ukumboza kufana ngaphandle kokuvuza. Inani le-zinc lingahlangabezana nezidingo ze-A475-09, izinga A.
