Thaum lub sijhawm tsim cov qauv thiab cov tsev, cov phab ntsa hollow feem ntau yog ua los ntawm cov pob zeb ntxiv. Txawm li cas los xij, ob peb tus neeg paub tias cov phab ntsa zoo li cas thiab lawv cov yam ntxwv zoo li cas. Yog li ntawd, ua ntej siv cov qauv no rau kev tsim kho, nws tsim nyog kawm tag nrho lawv cov yam ntxwv.
Types of reinforced concrete slabs
Nyob ntawm qhov muaj pes tsawg leeg thiab hom kev tsim kho, cov pob zeb ua kom muaj zog yog cov hauv qab no:
- Txhim kho pob zeb slabs nrog kev tsim kho. Cov khoom no muaj nyob rau hauv ntau qhov sib txawv. Lawv qhov ntev sib txawv ntawm 1790-6260 mm, dav 1200-4500 mm, thiab thickness 120 mm, 170 mm, 210 mm. Hom khoom no muaj qhov loj loj. Lawv qhov hnyav nyob ntawm qhov loj ntawm slab nws tus kheej thiab thaj tsam ntawm 0.625 tons txog 3.7 tons. Qhov siab qhov ntev ncav cuag 220 mm. Cov khoom no yog siv los npog cov phab ntsa hauv cov tsev nyob thiab cov tsev pej xeem.
- Slabs nrog puag ncig voids. Cov no kuj yog cov qauv loj heev. Daim hlau nrog qhov dav ntawm 100 hli muaj qhov ntev ntawm 240-1200 hli, nrog qhov davnyob rau hauv 120 mm - 170-890 mm, nrog ib tug dav ntawm 150 mm - 240-890 mm. Lawv qhov siab ncav cuag qhov siab tshaj plaws ntawm 220 mm. Tab sis tsis zoo li cov pob zeb hauv pem teb, cov pob zeb ua kom muaj zog hollow-core slabs muaj suab zoo thiab rwb thaiv tsev kub. Cov ntsuas no yog muab los ntawm qhov muaj qhov tsis muaj nyob rau sab hauv ntawm lub slab.
- daim phiaj tshwj xeeb. Cov qauv tsim no tsuas yog tsim rau balconies, loggias, bay qhov rais thiab cov kav dej sib tshooj. Lawv qhov sib txawv nyob rau hauv qhov tseeb tias tus tsim muaj qhov tshwj xeeb rau tso cov kav dej. Qhov siab ntawm cov qauv no yog 200 hli.
- Slabs nrog ribbed qauv. Lawv yog siv los npog cib vaj tse thiab pej xeem vaj tse, thiab kuj yog siv ntau heev los pab txhawb lub hauv paus ntawm lub ru tsev. Lawv loj heev. Lawv qhov ntev tuaj yeem ncav cuag 18 meters, dav - 3 meters, thiab qhov siab - los ntawm 600 mm txog 800 mm.
- Tshuaj pem teb slabs. Lawv raug ntsia nruab nrab ntawm cov kab ntawm cov tsev. Cov slabs ntev txog li 1.5 meters.
- pob zeb hnyav hnyav. Cov qauv no tau nruab nruab nrab ntawm cov kab hauv pem teb.
Txheej txheem ntawm hollow core slab phab ntsa
Tam sim no, hollow core slabs yog siv los tsim cov phab ntsa ntawm ntau lub tsev, nrog rau cov tsev nyob. Qhov no yog to taub, vim hais tias cov pob zeb ua pob zeb hollow phab ntsa muaj cov yam ntxwv zoo tshaj plaws thiab zoo.
Nws tsim nyog them nqi tshwj xeeb rau cov qauv hauv qab no:
- Vim qhov tseeb tias muaj cov voids hauv cov vaj huam sib luag, lawv yooj yim heev rauntsia thiab lub nra ntawm phab ntsa txo qis heev.
- Voids muab cov thermal rwb thaiv tsev zoo, thiab yog li ntawd cov phab ntsa tsis tas yuav tsum tau insulated ntxiv.
- Lwm yam zoo yog lub suab tsis zoo. Txawm tias muaj tseeb hais tias lub thickness ntawm cov phab ntsa reinforced pob zeb tsis hloov, lub suab rwb thaiv tsev yog siab heev. Sab nraum lub suab thiab suab nrov tsis nkag mus rau hauv phab ntsa.
Slab xaiv cov qauv rau cov phab ntsa hollow
Nws yog ib qho tseem ceeb tshwj xeeb yog xaiv cov qauv tsim nyog rau kev tsim cov phab ntsa hollow. Yog li ntawd, ua ntej koj pib ua cov phab ntsa hollow los ntawm cov pob zeb muaj zog, koj yuav tsum xyuam xim rau cov khoom ntawm cov phiaj.
Ntau tus neeg xav tias lawv txawv ntawm qhov tsis sib xws thiab qhov ntau thiab tsawg, tab sis qhov no tsis muaj tseeb. Hollow core panels kuj muaj cov yam ntxwv tshwj xeeb uas muaj txiaj ntsig zoo hauv kev tsim vaj tsev thiab cov tsev pej xeem.
Txoj kev sib txawv rau cov tub ntxhais hollow panels
- thawj tus yam ntxwv txawv yog txoj kev txhawb nqa. Nyob ntawm seb hom slab, qhov cuab lub zog tuaj yeem yog prestressed lossis tsis-prestressed. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho, panels nrog prestressed reinforcement yog siv.
- Lwm qhov tseem ceeb yog tus naj npawb ntawm sab ntawm kev txhawb nqa ntawm tag nrho cov qauv. Yeej, tag nrho cov qauv hollow tso cai rau kev txhawb nqa tsuas yog ob sab luv. Tab sis qee zaum muaj cov qauv nrog kev txhawb nqa ntawm peb lossis plaub sab.
- Tsim nyog nwsxyuam xim rau txoj kev ua daim hlau. Yeej, hollow reinforced pob zeb slabs yog tsim nrog ob lub cim PC lossis PB. Nyob ntawm qhov no, txoj kev tsim cov qauv tsim ntawm cov khoom no txawv.
Qhov txawv ntawm PB hollow core panels thiab PC
Panels nyob rau hauv lub hom PB yog tsim los ntawm casting nruam formwork. Lawv muaj lub tiaj tus thiab du nto, thiab lawv yuav luag tsis tawg. Cov qauv tsim no siv peev kev tsim kho. Reinforced qhob slabs ntawm hom no tuaj yeem yooj yim txiav lengthwise los yog nyias nyias, thiab lawv tuaj yeem beveled ntawm lub kaum sab xis ntawm 30 txog 90 degrees. Nyob rau tib lub sijhawm, lawv cov qauv txhawb nqa tsis raug ua txhaum cai. Cov khoom no ua rau nws yooj yim dua rau kev ua haujlwm ntawm qhov chaw tsim kho.
PK-branded slabs yog cam khwb cia hauv formwork. Nrog rau qhov ntev txog li 4.2 meters, lawv tuaj yeem tsim tau yam tsis muaj kev txhawb nqa. Tsis tas li ntawd, lawv muaj dawb deflection.
Cov yam ntxwv ntawm slab installation thaum lub sij hawm tsim kho ntawm hollow core phab ntsa
Tau kawg, txhawm rau txhawm rau cov pob zeb ua pob zeb ua kom muaj zog thiab muaj zog, cov vaj huam sib luag yuav tsum raug teeb tsa kom raug.
Kev txhim kho ntawm cov phab ntsa hollow muaj cov kauj ruam hauv qab no:
- Vim tias hollow core slabs ntawm PB hom tsis muaj mounting loops rau mounting, loading thiab unloading ntawm cov qauv no yuav tsum tau nqa tawm siv mos chocks los yog ib tug tshwj xeeb traverse.
- Txhawm rau rub cov chalk tawm hauv qab lub vaj huam sib luag, nws yog qhov yuav tsum tau tso qhov sib txawv me me rau lub vaj huam sib luag tom ntej thaum tso. Tom ntej no, lub phaj uas twb tau teeb tsa lawm yuav tsum tau txav mustus crowbar mus rau lub vaj huam sib luag tom ntej.
- Nws tsim nyog saib tus nqi ntawm qhov tsawg kawg nkaus qhov tob ntawm kev txhawb nqa rau cov qauv. Cov duab no nyob ntawm seb hom phab ntsa. Piv txwv li, rau cov phab ntsa cib, qhov tsawg kawg nkaus qhov tob yuav tsum yog 8 cm, thiab qhov loj tshaj plaws yog 16 cm, rau ib tug reinforced pob zeb phab ntsa, feem, 7 cm thiab 12, rau roj thiab ua npuas ncauj qhob blocks - los ntawm 10 mus rau 15, rau steel lug - 7 cm.
- Ua ntej koj pib txhim kho cov vaj huam sib luag, koj yuav tsum tau rauj qhov kawg ntawm lub qhov nrog voids. Voids tuaj yeem raug kaw nrog cov ntoo lossis cov tawg ntawm cov cib. Qhov no yog ua kom tsis txhob muaj dej nkag mus rau hauv cov qauv. Vim li no, kev pabcuam lub neej ntawm cov phab ntsa hollow nce, lawv tsis tawg, tsis tawg.
- Tom qab cov slabs tiav lawm, nws yog ib qho tsim nyog yuav tsum thauj tog rau nkoj thiab sau cov kab nrib pleb nrog cov cement. Rau PC npav daim hlau, lub thauj tog rau nkoj yog hooked mus rau lub qhov muag mounting thiab lub void yog ntim nrog cement.
Tsis tas li, ua ntej pib nrog kev teeb tsa ntawm cov qauv hollow, koj yuav tsum xaj lub crane. Nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account qhov loj ntawm txoj kev nkag, qhov siab tshaj plaws tau nthuav tawm ntawm lub tsheb crane thiab qhov ua tau ntawm qhov tso cai qhov hnyav ntawm crane.
Tus nqi ntawm hollow core reinforced pob zeb ua qauv
Tsawg tus neeg paub ntau npaum li cas hollow-core reinforced pob zeb nqi, tus nqi ntawm cov khoom no txawv txhua qhov chaw. Tau kawg, txhua yam nyob ntawm qhov zoo thiab tsim ntawm cov khoom no.
PK hom phaj nqi ntawm 2 txog 12 txhiab rubles. Thiab panels ntawm PB hom nqi ntawm 1500 rau 15 txhiab rubles. Tus nqi ntawm cov khoom no nyob ntawm qhov loj ntawm cov qauv, zoo thiab muaj pes tsawg leeg. Qhov zoo dua thiab loj dua lub phaj,tus nqi siab dua cov khoom.
