Siab Threaded Concrete Strand
Kev sib xyaw
1. steel hlau:
Lub steel hlau ntawm cov hlau strand yog ua los ntawm high-strength high-quality steel hlau. Nws yog feem ntau nto kho nrog galvanizing, aluminium plating, tin plating thiab lwm yam txheej txheem los tiv thaiv cov hlau hlau los ntawm xeb.
2.Core hlau:
Cov tub ntxhais hlau yog cov qauv kev txhawb nqa sab hauv ntawm cov hlau strand, feem ntau yog siv cov tub ntxhais hlau lossis cov tub ntxhais fiber ntau los xyuas kom meej qhov ruaj khov thiab khoov tsis kam ntawm cov hlau strand.
3. Txheej:
Cov txheej yog txheej tiv thaiv ntawm cov hlau strand, thiab nws txoj haujlwm yog los tiv thaiv cov hlau strand los ntawm corrosion, hnav thiab oxidation.
Nyob rau hauv luv luv, cov khoom ntawm steel strand muaj xws li steel hlau, core hlau thiab txheej. Qhov zoo thiab cov yam ntxwv ntawm cov khoom no yuav cuam tshuam ncaj qha rau kev ua haujlwm thiab kev pabcuam lub neej ntawm steel strand. Yog li ntawd, thaum xaiv steel strands, nws yog ib qhov tsim nyog los xaiv cov khoom tsim nyog steel strand thiab qauv raws li cov kev xav tau tshwj xeeb thiab ib puag ncig kom ntseeg tau tias nws muaj kev nyab xeeb thiab ua haujlwm zoo thaum siv.
Txheej txheem installation
1. Khoom siv:
Ua ntej, cov ntaub ntawv thiab cov khoom siv xws li cov hlua steel thiab bolts yuav tsum tau npaj.
2. Laying tawm thiab kos bolts:
Raws li cov qauv tsim, cov hlua hlau tau muab tso rau ntawm cov txuas hniav, viaducts thiab lwm cov qauv uas yuav tsum tau muaj zog ntxiv load-bearing thiab av qeeg. Tom qab ntawd, ntxig lub ntsia liaj qhov rooj rau hauv qhov kawg npog qhov thiab nruj nreem ntsia hlau nrog pneumatic wrench.
3. Stranding:
Lub prefabricated steel strands yog nteg ib sab ntawm ib sab ntawm racks thiab ces twisted.
4. Kev Nyuaj Siab:
Rub lub twisted steel strand mus rau qhov chaw ua ntej. Cov kauj ruam no yuav tsum tau siv lub tshuab tensioning los rub cov strands mus rau qhov ntev thiab nruj.
5.Anchorage:
Tom qab ua tiav cov tensioning ntawm steel strand, lwm kawg ntawm cov hlau strand yuav tsum tau ruaj khov kho ntawm lub thauj tog rau nkoj rau anchoring. Thaum ua haujlwm thauj tog rau nkoj, nws yuav tsum tau txiav txim siab hom thiab ntau npaum li cas ntawm cov thauj tog rau nkoj yuav tsum tau siv raws li lub zog rub thiab tus naj npawb ntawm cov hlua, thiab nruab tag nrho cov thauj tog rau nkoj sib npaug ntawm txhua txoj hlua. Tom qab kev teeb tsa, cov hlua rau tensioning thiab anchoring yuav tsum tau muab tso rau ntau tshaj 24 teev kom tos cov hlau strands kom khov.
6. Txau los tiv thaiv corrosion:
Tom qab lub tensioning thiab anchoring tiav lawm, cov hlau strands yuav tsum tau txau-coated rau kev tiv thaiv corrosion.
7. Txais:
Thaum kawg, tom qab ua tiav kev kho, cov strands raug tshuaj xyuas thiab txais. Kev tshuaj xyuas thiab kev lees paub yuav tsum suav nrog kev sim ntawm qhov pom, lub zog tensile thiab tus naj npawb ntawm cov hlua ntawm cov hlau.
Qhov zoo
1. Hnav tsis kam:Vim tias cov hlua hlau yog ua los ntawm ntau cov hlau xaim thiab muaj qhov tawv tawv, lawv cov kev hnav tsis zoo yog qhov zoo tshaj rau lwm cov ntaub ntawv thaum qhov hnyav tib yam.
2. Lub zog muaj zog:Vim hais tias cov hlau strand yog twisted nrog ntau cov hlau hlau, nws tuaj yeem tiv taus kev nqa thiab kev thauj mus los ntawm ntau cov khoom hnyav.
3. Corrosion kuj:Sab nraud ntawm cov hlua hlau feem ntau yog kho nrog galvanizing lossis lwm txoj hauv kev, uas tuaj yeem tiv thaiv cov hlua hlau los ntawm oxidized thiab corroded thaum siv.
4.High kub kuj:Lub hardness ntawm cov hlau strand txo qis tom qab cua sov, tab sis nws elasticity tseem tsis hloov thiab tuaj yeem tiv taus cov khoom hnyav hauv qhov kub thiab txias.
5. Kev kho yooj yim:Cov hlua hlau yuav tsum tau ntxuav thiab lubricated tsis tu ncua kom tswj tau lawv qhov zoo.
