Dab tsi yog qhov yuav tsum ua rau nruab lub tsev qauv ntawm lub caij ntuj no?
Ua ntej kev teeb tsa ntawm txoj haujlwm kem, txoj kab ib sab ntawm txoj kab axis yuav tsum muaj haum thiab qhov siab yuav tsum teeb tsa txoj kev txhawb nqa steel. Ntxiv rau qhov kom ntseeg tau qhov ruaj khov thiab ruaj khov ntawm cov kem formwork thiab kev txhawb nqa, cov ntawv sau siab thiab qis dua yuav tsum tau txais kev txhawb rau tib lub vev xaib ntsug. Kev tsim kho thaum lub caij ntuj no, dej khov, daus thiab av ntawm daim formwork yuav tsum tau tu kom huv ua ntej siv cov qauv, thiab cov sundries, dej khov thiab daus hauv cov qauv ntawv yuav tsum tau muab ntxuav kom huv tom qab daim ntawv ua tiav, thiab tsis muaj dej tso cai. Thaum muaj huab cua hlob (saum qib 5), lub rooj sib txoos thiab kev txwv tsis pub ua cov haujlwm loj.
Sab nraub qaum ntawm phab ntsa thiab kab kos duab tuaj yeem ua kom tiav nrog 50 hli tuab nplaim hluav taws-retardant polystyrene pawg thawj coj rau kev rwb thaiv tsev, thiab qhov sib txawv ntawm cov pawg hluav taws xob rwb thaiv tsev tau nce 1 ~ 2cm los xyuas kom meej tias lub rwb thaiv tsev hluav taws tsis poob. Nyob rau tib lub sijhawm, sab nraud yuav tsum muab ntim nrog xyoob cov nplaum los yog peb cov plywood. Thiab cov xyoob plywood lossis peb cov plywood yuav tsum tau rhuav thiab muab sib dhos nyob rau tib lub sijhawm ntawm daim qauv.
Lub nqaj sab hauv daim ntawv yuav tsum tau ua los ntawm 18mm tuab ntau txheej board; cov kab hauv qab daim ntawv yuav tsum yog 50 hli tuab ntoo thuv planed; cov ntaub ntawv hauv pem teb yuav tsum yog xya plywood lossis 18mm tuab ntau txheej txheej pawg thawj coj saib. Daim ntawv txhawb nqa yuav tsum tau tsim raws li qhov yuav tsum tau ua ntawm daim phiaj qauv, thiab kev txhawb nqa kom siab thiab arching qhov siab yuav tsum kuaj xyuas tom qab qhov erection tiav, thiab daim ntawv ua haujlwm slab yuav tsum tau tso dej ntws yaug mus rau sab nraud qhib ntawm nqaj sab daim ntawv, thiab yuav tsum tsis txhob muab tso rau saum nqaj sab. Cov ntsiab lus tseem ceeb rau rhuav ntawm lub tsev formwork: Thaum tus formwork yuav tsum tau rhuav pov tseg nyob rau lub caij ntuj no, daim ntawv thov tawg yuav tsum xa mus raws li cov cai, thiab daim ntawv qhia txog kev sim siab ntawm qhov ntsuas qhov demoulding sim yuav tsum suav nrog. Daim ntawv faus tsuas yog tuaj yeem rhuav tshem tom qab daim ntawv thov demolding raug pom zoo.
Qhov kev txiav txim siab tseeb thiab qauv txheej txheem ntawm kev tshem tawm template yuav tsum raug xaiv raws li qhov tsim nyog ntawm cov qauv tsim. Yog tias tsis muaj qhov tshwj xeeb yuav tsum tau ua, nws yuav tsum tau nqa tawm raws li lub hauv paus ntsiab lus ntawm kev txhawb nqa thawj zaug thiab tom qab ntawd tshem tawm, thiab cov khoom tsis thauj khoom ntawm cov qauv tsim nyog yuav tsum tau muab tshem tawm ua ntej, thiab tom qab ntawd cov load-cov kabmob qhov chaw ntawm tus qauv.
Nyob rau hauv ib puag ncig kub zoo, yog tias cov npoo thiab cov ces kaum thiab pob zeb saum npoo ntawm pob zeb tsis puas vim lub demolding ntawm phab ntsa, lub pwm tuaj yeem rhuav tshem; thiab nyob rau hauv qhov tsis zoo ib puag ncig kub, lub zog compressive ntawm qhov kev sim siab demoulded sim yuav tsum ncav cuag 4MPa thiab pob zeb ua kom tsis muaj kev cuam tshuam. Cov pwm tuaj yeem kho nyob hauv qhov chaw txias, thiab lub sijhawm rhuav tshem yuav tsum tswj xyuas kom nruj. Thaum qhov kub ntawm qhov sib txawv ntawm cov pob zeb thiab cov ib puag ncig sab nraud yog ntau dua 20 ° C, qhov saum npoo ntawm pob zeb yuav tsum tau them nrog polyethylene yas ntawv tom qab cov pwm raug tshem tawm, thiab saum npoo yuav tsum tau them ib ntus nrog lub hnab khib nyiab kom txias nws maj mam.
