Kev txhim kho ntawm PC Strands thiab Prestressed steel khoom anchorage systems

Prestressed steel khoom tau ua tiav zoo txij li xyoo 1950s ntawm lub xyoo pua xeem, muaj ob lub ntsiab lus tseem ceeb hauv nws txoj kev loj hlob. Ua ntej, lub zog ntawm cov khoom maj mam nce, kom txo qhov loj thiab qhov hnyav ntawm cov khoom siv prestressed, txawm tias txo qhov project nqi; Thib ob, los ntawm kev txhim kho lub zog, peb yuav tsum tau them sai sai rau kev tsim cov khoom siv nrog kev ua haujlwm siab tiv thaiv corrosion, txhawm rau txhim kho lub zog ntawm prestressed steel Cheebtsam thiab txuag cov nqi kho.

Raws li qhov siab-lub zog thiab tsis tshua muaj zog steel strands muaj kev txhawj xeeb, lawv txoj kev txhim kho yog kwv yees faib ua plaub theem: zoo tib yam du & tiaj steel strands - galvanized steel strands thiab unbonded steel strands - unbonded galvanized steel strands - epoxy steel strands. Nyob rau hauv thawj peb theem ntawm txoj kev loj hlob, lub thauj tog rau nkoj ua hauj lwm clips matched nrog steel strand yog roughly tib yam; Nws tsim, ua thiab ntau lawm tau ua loj-scale. Plaub theem ntawm txoj kev loj hlob, uas yog, epoxy steel strand, tam sim no muaj peb hom epoxy steel strand nyob rau hauv lub thoob ntiaj teb thiab domestic kev lag luam. Ib qho yog ib leeg-xaim nyias-txheej txheej epoxy steel strand, uas yog, xya hlau nyob rau hauv cov hlau strand yog coated nrog epoxy txheej nyias, thiab txheej thickness yog nyias (li 0.1 ~ 0.2 hli); Qhov thib ob yog coated epoxy coated steel strand, uas yog, txheej txheej ntawm cov hlau strand yog coated nrog epoxy txheej, thiab tsis muaj epoxy resin sau nyob rau hauv qhov sib txawv ntawm cov hlau strands, thiab lub thickness ntawm txheej epoxy txheej yog. (li 0.65 ~ 1.15mm); Qhov thib peb yog cov epoxy coated steel strand, uas yog ntim nrog epoxy resin ntawm txheej txheej thiab hauv qhov sib txawv, thiab tsuas yog epoxy steel strand uas ua tau raws li ASTM A882 / A882M-04a thiab ISO14655: 1999 tus qauv.

Lub prestressed anchorage system yog maj mam tsim nrog txoj kev loj hlob ntawm prestressed steel, ob leeg yog inseparable. Nrog rau kev loj hlob zuj zus ntawm cov muab tub lim epoxy coated steel strand thev naus laus zis, nws cov txheej txheem anchoring kuj tau maj mam tsim thiab txhim kho. Ob leeg koom tes nrog ib leeg, thiab tau siv rau ntau txoj kev loj choj kev tsim kho xws li cov txuas txuas txuas txuas, ib feem ntawm cov txuas txuas txuas txuas, sab nraud prestressing, arch choj khi rods thiab pob zeb staggering.

Univac Tshiab Khoom Tech.Manufacturing Co., Ltd. yog ib tug kws chaw tsim tshuaj paus thiab distributor ntawm high-strength thiab low-so prestressed steel strands, prestressed steel hlau, kub-dip galvanized steel strands, unbonded steel strands, epoxy-coated steel strands thiab Lawv cov kev txhawb nqa kev txhawb nqa, qhov zoo ntawm cov khoom siv steel prestressed siab ua tau raws li cov qauv thoob ntiaj teb BS 5896: 2012, FprEN 10138: 2009, ASTM A416 / 416M: 2012, ISO 14655: 1999 "Epoxy Coated Steel Grain Concrete" thiab cov kev cai ntawm American standard ASTM A882 / A882M-04a "Standard Specification for Filled Epoxy Coated Xya Hlau Prestressed Steel Strands"; Lub kaw lus anchoring tau ua tiav cov kab ke-nyob rau hauv cable system, cable-nyob system rau qee qhov txuas txuas txuas hluav taws xob, sab nraud prestressing system, arch choj khi system thiab geotechnical anchorage system, uas tau siv rau hauv ntau txoj haujlwm.
