Ukuphuhliswa kwePC Strands kunye nePrestressed steel product systems anchorage

Iimveliso zetsimbi ezigxininisiweyo zenze inkqubela phambili ukususela kwi-1950 yekhulu leminyaka edlulileyo, kukho iingongoma ezimbini eziphambili kwi-trajectory yayo yophuhliso. Okokuqala, amandla ezinto eziphathekayo ayanda ngokuthe ngcembe, ukuze anciphise ubungakanani kunye nobunzima bamacandelo agxininiswe ngaphambili, ade anciphise iindleko zeprojekthi; Okwesibini, ngesiseko sokuphucula amandla, kufuneka sinikele ingqalelo ekuphuhlisweni kwezixhobo ezinomsebenzi ophezulu wokuchasana nokubola, ukwenzela ukuba kuphuculwe ukuqina kwamacandelo ensimbi agxininiswe kunye nokugcina iindleko zokugcina.

Ngokubhekiselele kwimisonto yentsimbi ephezulu kunye neyokuphumla ephantsi, inkqubo yabo yophuhliso yahlulahlulwe ngokwezigaba ezine: imisonto yentsimbi eqhelekileyo egudileyo kunye necacileyo - imisonto yentsimbi ekhuniweyo kunye nemisonto yentsimbi engadityaniswanga - imisonto yentsimbi engadityaniswanga - epoxy imisonto yentsimbi. Kwizigaba ezintathu zokuqala zophuhliso, iikliphu zokusebenza ze-anchor ezihambelana nentsimbi yentsimbi ziphantse zifana; Uyilo, ukusetyenzwa kunye nokuveliswa kwayo kuye kwaba ngomlinganiselo omkhulu. Inqanaba lesine lophuhliso, oko kukuthi, i-epoxy steel strand, okwangoku kukho iintlobo ezintathu ze-epoxy steel strand kwiimarike zamazwe ngamazwe kunye nezasekhaya. Enye i-single-wire thin-layer epoxy strand yensimbi, oko kukuthi, iingcingo ezisixhenxe zentsimbi kwi-strand yensimbi zifakwe kwi-epoxy coating ngokwahlukileyo, kwaye ubukhulu bengubo buncinci (malunga ne-0.1 ~ 0.2mm); Okwesibini yi-coated epoxy coated strand yensimbi, oko kukuthi, umaleko wangaphandle we-strand wentsimbi ugqunywe nge-epoxy coating, kwaye akukho resin ye-epoxy egcwalisa umsantsa phakathi kweentambo zentsimbi, kunye nobukhulu be-epoxy yangaphandle. (malunga ne-0.65 ~ 1.15mm); Eyesithathu i-epoxy coated steel strand, ezaliswe nge-epoxy resin kwi-external layer kunye ne-gap, kwaye iyona kuphela i-epoxy strand yensimbi edibana ne-ASTM A882 / A882M-04a kunye ne-ISO14655: imigangatho ye-1999.

Inkqubo ye-anchorage ene-prestressed iphuhliswa ngokuthe ngcembe kunye nokuphuhliswa kwentsimbi egxininisiweyo, zombini ayinakuhlukaniswa. Ngokukhula ngokuthe ngcembe kwetekhnoloji ye-filler epoxy coated steel strand, inkqubo yayo yokubambelela nayo iye yaphuhliswa ngokuthe chu kwaye yaphuculwa. Ezi zimbini ziyasebenzisana omnye komnye, kwaye ziye zasetyenziswa kwiiprojekthi ezininzi zolwakhiwo lwebhulorho yohola wendlela efana neebhulorho ezihlala ngeentambo, iibhulorho ezihlala iintambo ezingagqibelelanga, uxinezeleko lwangaphandle, iibhulorho zokubopha iiroli kunye namatye ahexayo.

I-Univac New Material Tech.Manufacturing Co., Ltd. ngumenzi oqeqeshiweyo kunye nosasazo lwemisonto yentsimbi ephezulu kunye neyokuphumla ephantsi, iingcingo zentsimbi ezicinezelekileyo, imisonto yentsimbi eshushu-diphu, imisonto yentsimbi engabotshwanga, imisonto yentsimbi egqunywe nge-epoxy kunye iinkqubo zabo zokubambelela ezixhasayo, umgangatho weemveliso zetsimbi ezigxininisiweyo zihambelana ngokupheleleyo nemigangatho yamazwe ngamazwe BS 5896:2012, FprEN 10138:2009, ASTM A416 / 416M: 2012, ISO 14655: 1999 "Iimfuno ze-Epoxy Coated Steel Grain Wire for Prestress" yomgangatho waseMelika we-ASTM A882/A882M-04a "Inkcazo eMiselweyo ye-Epoxy eZalisiweyo eQotywe ngocingo oluSixhenxe lweMitya yentsimbi ecinezelekileyo"; Inkqubo ye-anchoring iphuhlise ngempumelelo inkqubo ye-cable-stayed cable, i-cable-stayed system yezinye iibhulorho ezihlala kwi-cable, inkqubo ye-prestressing yangaphandle, inkqubo ye-arch bridge tie kunye ne-geotechnical anchorage system, esetyenziswe kwiiprojekthi ezininzi.
