Kushushu - Dipped Galvanized Prestressed Steel Strand
Intshayelelo yeMveliso
I-Hot-Dipped Galvanized PC Strand ephantsi yokuphumla ephantsi ecinezelwe umsonto wentsimbi yenziwe ngeengcingo zentsimbi ezisixhenxe ezishushu eziditshiweyo ezingqukuva ezinokumelana ne-corrosion, ezinokwandisa ngokufanelekileyo ubomi bamacandelo kwimeko yendawo enomhlwa efana nemimandla eselunxwemeni, eyaziwa njenge. indlela esebenzayo yokuthintela umhlwa ngoku nakwihlabathi jikelele.
Lo mgangatho usebenza kwintambo yebhulorho, amacandelo oxinzelelo olusisigxina, ukuphakamisa okanye ukulungisa iindawo ezixineneyo zezakhiwo kunye nezinye izakhiwo ezicinezelekileyo, ezingasetyenziswa ngokuthe ngqo kulwakhiwo lwe-concrete grouting, ububanzi: 12.7mm, 15.mm, 15.7mm, 17.8mm, amandla iklasi: 1770MPa, 1860 MPa, 1960MPa. (emva koku kuthiwa yi "steel strand").
Ulwakhiwo lwe-1x7, i-1x19 eshushu editshiweyo yeemveliso zochungechunge lwentsimbi, amandla okuqina anokufikelela kwi-1860MPa kunye neenkcukacha ezifanayo njengentsimbi ecacileyo & ejikelezileyo yePC yentsimbi ngokwemigangatho yokusebenza acc.to GB/T 33363, ASTM A416, EN101896, BS5 kunye ne-NFA35-035 njl.
Iimpawu zeMveliso
Imveliso inokuveliswa ngokwezicelo ze-zinc zokugqoka ezivela kubathengi, i-zinc yokugqoka inokufikelela kwi-250 gsm okanye ngaphezulu, ukufana kwe-zinc layering layer ngamaxesha angama-3-4 ngaphandle kokubeka ubhedu, kwaye ukunamathela akuphuli kwaye akuxoki. phantsi kwemeko ngokujija izangqa ezisi-8 emva kokuba zinc zigqunywe.
Ngokuxhomekeke kwizixhobo eziphambili zenkampani, sinokuyila inkqubo yegalvanized ukuhlangabezana neemfuno ezikhethekileyo zabasebenzisi kumgangatho we-zinc layer, umgangatho womhlaba, njl.
Ukuthelekisa ne-PC steel strand ngaphandle kokugquma kunye ne-galvanized PC steel strand, yangaphambili yabonakala ibomvu ebomvu emva kovavanyo lokutshiza ityuwa kwiiyure ze-24.
Isampulu yotshintsho lwentsimbi yentsimbi yePC ngaphandle kokugquma kunye nentsimbi yentsimbi ye-PC emva kweentsuku ezingama-21 zovavanyo lokutshiza ityuwa ngokungathathi hlangothi ngolu hlobo lulandelayo,
Izicelo zeMveliso
1)Iimveliso zingasetyenziswa kubunjineli bokwakha kunye nenkxaso yendlela yendlela yokuxhasa umgodi wamalahle phantsi kweemeko ezirhabaxa zokusingqongileyo.
2) Kwiminyaka yakutshanje, isetyenziswe nakwintsimi yamandla omoya. "I-1x7-ephakathi 21.6mm, i-PC Steel Strand eyi-1x7-ephakathi, i-Steel Strand ye-Steel Strand enkulu yobukhulu obuyi-Hot-Dipped, esetyenziswe kwi-"160m yokuqala", inqaba yomoya ophantsi kwesantya esiphantsi somoya, ephethe umthamo ophezulu wokuthwala, oqhuba ukuphucula ukuxhathisa umoya kwinqaba. Ngokuxhathisa kakuhle kwe-corrosion, enokwandisa ubomi benkonzo yenqaba.
Inqaba yokuqala yehlabathi yovavanyo olukwi-160m yesantya somoya eShandong
