Aluminium alloy formwork yog qhov ua rau muaj kev puas tsuaj xws li qhov chaw dents, warping deformation, tus pin qhov hnav, rib cracking, thiab txheej corrosion thaum lub sij hawm txheej txheem ntawm formwork tshem tawm, tsheb thauj mus los, thiab stacking. Kev quab yuam hnyav thiab kho qhov muag tsis pom kev vuam ntawm qhov chaw yuav ua rau muaj kev nyab xeeb ntawm pwm nthuav dav thiab pwm tawg. Ua raws li kev txheeb xyuas kev puas tsuaj, kev kho tus qauv, kho qhov rov kuaj xyuas dua thiab cov kab liab dawb raws li cov lus qhia tshwj xeeb yog qhov tseem ceeb txhais tau tias txo cov nqi, nce kev ua tau zoo thiab txuas ntxiv lub neej hloov pauv ntawm txhuas pwm.
Nrog rau kev nce qib sai ntawm cov tsev prefabricated, aluminium alloy formwork tau dav siv vim nws qhov zoo ntawm lub teeb yuag, kev sib dhos ceev, thiab ntau yam kev hloov pauv. Txawm li cas los xij, ntau cov khoom siv txhuas txhuas tau raug puas ntsoog mus rau qhov sib txawv vim kev rhuav tshem, sib tsoo, hloov mus rau qhov tsis zoo, thiab tsis sib xws ntawm qhov chaw tsim kho. Muaj ob qho kev nkag siab yuam kev hauv ntau qhov haujlwm: lawv yuav raug muab pov tseg ncaj qha vim kev puas tsuaj, uas yuav ua rau cov khoom siv ntxiv; los yog lawv yuav txuas ntxiv siv yooj yim los ntawm kev kho thiab vuam, uas yuav ua rau muaj kev phom sij loj. Raws li JG / T 522-2017 aluminium alloy formwork tus qauv, kev lag luam tau maj mam ua tiav cov txheej txheem kev ua haujlwm thiab kev saib xyuas uas suav nrog kev ntsuas ntsuas, cais kev saib xyuas, kho thiab rov tshuaj xyuas, thiab yuav tsum tau muab pov tseg kom sib npaug ntawm kev nyab xeeb thiab nyiaj txiag txiaj ntsig.
Ib. Kev txiav txim siab ntawm kev puas tsuaj rau kev faib tawm, qhov sib txawv ntawm kev kho thiab qhov tsim nyog scrapping
Ua ntej kho, ua qhov zoo li + ntsuas cov cuab yeej tshuaj xyuas los xyuas qhov flatness ntawm lub rooj tsavxwm nto, cov hlua txuas ntxiv, welds, pin qhov, thiab phab ntsa tuab, uas tau muab faib ua peb pawg: me ntsis, nruab nrab, thiab kev puas tsuaj loj.
1. Kev puas tsuaj me me (tuaj yeem kho tau yooj yim ntawm qhov chaw): khawb ntawm lub rooj tsavxwm nto, qhov chaw ntiav, thiab me ntsis warpage; cov ribs reinforcing yog zoo lawm, tsis muaj kab nrib pleb los yog kua muag, tus pin qhov tsis zoo, thiab phab ntsa thickness tsis thinned, uas tsis cuam tshuam rau cov qauv kev nyuaj siab.
2. Kev puas tsuaj loj (yuav tsum tau ua haujlwm hauv chaw ua haujlwm lossis rov qab mus rau lub Hoobkas kho): Cov qauv muaj qhov pom tseeb warping deformation, cov dents hauv zos, thiab txheej txheej oxidation corrosion; tsis muaj cov kab nrib pleb, cov ribs reinforcing tsis tawg, thiab cov pin qhov yog me ntsis deformed. Kev kho nruj nrog rauj raug txwv nyob rau hauv qhov chaw tsim kho.
3. Kev puas tsuaj loj heev (kev kho yog txwv tsis pub thiab muab pov tseg ncaj qha): cov kab nrib pleb thiab kua muag tshwm rau ntawm cov vaj huam sib luag thiab kev txhawb nqa tav; mus tas li deformation
tshaj qhov tso cai sib txawv ntawm qhov specification; cov khoom siv hauv paus yog hnav thiab cov phab ntsa thickness yog thinned tshaj tus qauv; tus pin qhov yog torn thiab nthuav; lub ntsiab weld yog tawg. Yog tias cov kab nrib pleb tshwm nyob rau hauv qhov kev ntxhov siab-kev coj tus kheej, nws tsis raug tso cai txuas ntxiv kev tsim kho tom qab vuam qhov cuab yeej los tiv thaiv cov khoom tsis ua haujlwm thaum lub sij hawm nchuav.
2. Cov txheej txheem kho cov txheej txheem rau ntau hom kev puas tsuaj
1. Warp deformation kho
Me ntsis deformation: Siv ib lub rauj roj hmab los kho me ntsis deformation los ntawm khob ntoo nyob rau hauv qhov opposite direction. Nws yog nruj me ntsis txwv tsis pub ntaus cov khoom siv txhuas ncaj qha nrog rauj kom tsis txhob tsim cov pits tshiab thiab zais micro-cracks.
Nruab nrab warpage: Siv hydraulic tooling rau txias calibration, maj mam pressurize thiab maj mam pib dua; Kev kho qhov kub thiab txias yog txwv tsis pub, vim tias qhov kub thiab txias yuav hloov cov khoom ntawm aluminium alloy cov ntaub ntawv thiab txo lub zog ntawm cov khoom. Tom qab kho, qhov flatness yuav tsum tau ntsuas dua thiab kev kam rau siab yuav tsum tau ntsib ua ntej hloov.
2. Cov qhov dej thiab pob ntawm lub rooj tsavxwm
Cov pits ntiav raug thawb tawm ntawm lub nraub qaum ntawm lub formwork thiab rov pib dua; me me tsis xws luag nyob rau hauv qhov chaw uas tsis muaj kev ntxhov siab yog sau, polished thiab leveled nrog aluminium kho compound, uas tsuas yog kho cov tsos, tab sis tsis rov qab muaj zog cov qauv.
Yog hais tias lub qhov dej yog nyob rau ntawm lub reinforcing rib, txawm tias qhov zoo li rov qab los, nws tseem yuav tsum tau soj ntsuam xyuas kom pom cov kab nrib pleb zais. Yog tias pom qhov tawg, nws yuav muab pov tseg ncaj qha.
3. Corrosion thiab txheej puas kho
Ua tib zoo tshem tawm cov pob zeb seem thiab cov roj stains, tshem tawm cov oxidized corrosion txheej nrog cov ntawv xuab zeb lossis hlau txhuam, ntxuav thiab qhuav; siv cov tshuaj tiv thaiv corrosion primer thiab tshuaj tsuag txuam tiv thaiv topcoat.
Yog hais tias corrosion tau eroded lub hauv paus cov ntaub ntawv thiab ua rau cov phab ntsa thickness ua thinner, tsis txhob pleev xim rau npog qhov tsis xws luag thiab ncaj qha mus khawb nws.
4. Txhaum thiab puas kho vuam tswj
Raws li txoj cai, yog tias muaj cov kab nrib pleb hauv lub vaj huam sib luag loj thiab lub ntsiab lus tseem ceeb ntawm cov formwork, lawv yuav tsis raug kho thiab rov siv dua.
Tsuas yog qhov tsis muaj kev ntxhov siab ntawm cov ces kaum yuav raug kho los ntawm argon arc vuam los ntawm cov kws muaj ntawv pov thawj. Tom qab vuam, lawv yuav polished thiab smoothed. Kev tshuaj xyuas Penetrant yuav raug ua los kuaj xyuas cov kab nrib pleb zais, thiab kev tshuaj xyuas qhov ntsuas yuav ua tiav. Kev kho vuam thiab rov siv dua ntawm cov kab nrib pleb hauv thaj chaw muaj kev ntxhov siab raug txwv nruj heev.
5. Lub qhov pin yog hnav thiab puas.
Lub qhov pin tau hnav thiab o, yog li siv lub bushing los kho nws; cov khoom siv aluminium nyob ib ncig ntawm lub qhov tau torn thiab tawg, yog li cov formwork raug scrapped.
3. Kev tshuaj xyuas tom qab kho kom tsis txhob "tso rau hauv kev siv cov kab mob"
Kev kho tsis tau txhais hais tias nws tsim nyog. Peb cov txheej txheem tshuaj xyuas yuav tsum tau ua tom qab kho tiav:
1. Dimensional soj ntsuam: flatness, kab pheeb ces kaum, tus pin qhov txoj hauj lwm, raws li txhuas alloy template kam rau ua;
2. Kev kuaj pom qhov tsis zoo: Tshawb xyuas txoj haujlwm kho thiab vuam txoj haujlwm txhawm rau kuaj xyuas cov micro-cracks tshiab;
3. Kev tshuaj xyuas Batch: Batch kho Cheebtsam raug coj mus kuaj xyuas qhov deformation.
Cov khoom kho kho yuav tsum raug cim thiab sau tseg los sau cov hom kev puas tsuaj, kev kho cov txheej txheem, thiab kev soj ntsuam xyuas kom ua tiav kev tswj xyuas cov khoom.
4. Pem hauv ntej-kawg tswj kom txo cov template puas
1. Nws yog nruj me ntsis txwv tsis pub pry lossis smash nyuaj thaum dismantling pwm. Qhov tseem ceeb yuav tsum tau muab tshem tawm cov pins kom txo tau qhov cuam tshuam deformation;
2. Yuav tsum muaj cov ntaub qhwv ntoo nyob hauv qab ntawm kev hloov thiab stacking. Nws yog txwv tsis pub pov los yog pawg nyob rau hauv lub siab hnyav;
3. Ntxuav lub pob zeb kom raws sij hawm tom qab tig, thiab nws yog txwv tsis pub ua phem rau cov slab nrog ib tug steel chisel;
4. Lub tsev kawm ntawv tau muab faib ua thaj chaw yuav tsum tau ntxuav, thaj chaw yuav tsum tau soj ntsuam, kho qhov chaw, thiab thaj chaw tsim nyog. Cov khoom puas raug muab cais. Cov qauv uas tsis tau tshuaj xyuas yog txwv tsis pub mus ncaj qha mus rau qhov chaw ua haujlwm.
Kev lag luam xaus
Aluminium alloy formwork kho tsis yog tsuas yog hais txog kev kho lub ntsej muag, lub hauv paus yog los xyuas kom meej qhov kev nyab xeeb thiab kev ua tau zoo ntawm cov qauv. Kev kho qhov muag tsis pom kev thiab rov siv dua dhau ntawm tus ciam teb yuav ua rau muaj kev pheej hmoo ntawm kev sib tsoo; kev hloov ncaj qha ntawm txhua tus yuav ua rau tus nqi tsim nyog. Ua raws li kev faib tawm kev puas tsuaj, kev saib xyuas tus qauv, kev tshuaj xyuas nruj dua, thiab nruj me ntsis ua raws li cov kab hauv qab no tuaj yeem ua kom muaj txiaj ntsig zoo ntawm txhuas pwm thiab ua tiav qhov kev yeej-yeej rau kev tsim kho kev nyab xeeb thiab kev tswj tus nqi.
