PK pem teb slabs yog puag ncig-hollow reinforced qhob load-bearing qauv tsim los npog txhua qhov chaw. Lub neej kev pab cuam ntawm ib lub tsev qauv nyob ntawm qhov zoo ntawm lawv cov khoom. Yuav ua tau los ntawm lub teeb, ntom thiab hnyav silicate pob zeb.
PC pem teb slabs sib txawv hauv qhov tsis muaj qhov taub thiab tuab. Lawv yuav tsum tau ua raws li tag nrho cov kev cai ntawm lub xeev cov qauv rau kev tsim (nyob rau hauv cov nqe lus ntawm rigidity, lub zog, tawg kuj). Cov kev cai tseem ceeb muab tso rau pem hauv ntej rau PC pem teb slabs tsis yog tsuas yog kev ntseeg siab, tab sis kuj muaj suab nrov rwb thaiv tsev. Lawv txawv los ntawm kev txhim kho cov khoom tiv thaiv kev tsim cov kab nrib pleb thiab chips. Lawv yog tsim los ntawm ob qho tib si nrog kev siv cov kev txhawb zog siab thiab cov pa. Qhov no yog lawv qhov sib txawv tseem ceeb ntawm beam pem teb slabs PB, uas yog tsim los ntawm kev pab los ntawm prestressed reinforcement. Tsis tas li ntawd, tom kawg muaj cov yam ntxwv ntawm lub cev hloov tau yooj yim, tso cai rau kev teeb tsa nrog txhua lub suab, thiab tseem tso cai rau koj los ua ib qho slab ntawm yuav luag txhua yam duab. PC pem teb slabsmuaj cov kev xav tau nruj dua, tab sis muaj ntau qhov ntom ntom thiab muaj zog dua ntawm cov yam ntxwv kink / khoov.
Thaum lifting thiab mounting PC pem teb slabs, siv tshwj xeeb gripping pab kiag li lawm los yog mounting loops. Hauv kev tsim cov khoom siv hauv tsev no rau kev sib dhos tsis sib haum, qhov ntev thiab qhov chaw ntawm lub qhov tau muab ua ntej hauv cov duab kos ntawm cov ntaub ntawv ua haujlwm.
txhawm rau txhawm rau cov khoom siv hauv tsev ntxiv kom tsis txhob poob lawv cov khoom sib txawv, cov cai khaws cia yuav tsum tau ua raws: qhov siab thaum stacking stacks yuav tsum tsis txhob ntau tshaj ob thiab ib nrab metres, thaum lub sijhawm khaws cia ntev yuav tsum tau ua. so lawv ntawm ntoo blocks. Xws li cov hauv ob sab phlu yog nyob ze rau qhov tshwj xeeb mounting loops.
Hollow floor slabs yog npaj rau kev tsim kho ntawm cov kabmob ntawm cov qauv thiab cov qab nthab rau ntau lub hom phiaj. Lawv raug siv nruj raws li cov duab kos thiab cov kev xav tau ntxiv uas tsim nyog.
Hollow cov qauv, raws li lub xeev cov qauv, raug cim nrog cov cim. Nws muaj cov pab pawg uas suav nrog tsab ntawv thiab tus lej sib cais los ntawm hyphen. Thawj ntu qhia txog hom hollow core slab, nws qhov yuav tsum tau ua, sib npaug rau tus lej ze tshaj plaws, uas ntsuas hauv decimeters. Qhov thib ob qhia txog tus lej serial raws li qhov yuav tsum tau muaj peev xwm bearing lossis tus qauv tsim. Tsis tas li ntawd, lawv qhia cov chav kawm ntawm cov hlau reinforced thiab hom pob zeb (lawv tsis qhia cov ntawv hnyav, lub teeb - L, silicate.tuab - C). Pab pawg thib peb suav nrog cov kev txwv ntxiv.
Ribbed pem teb slabs yog tsim rau hauv pem teb nyob rau hauv ntau-storey tsev los yog industrial thaj chaw nrog ib tug tsawg kawg nkaus kauj ruam ntawm rau meters. Lawv qhov siab yog plaub puas millimeters (raws li lub xeev tus qauv 27215-87) los yog peb puas millimeters (raws li lub xeev tus qauv 21506-87).
Cov plag tsev tsis muaj dab tsi, uas yog ua nrog cov voids sib npaug (qhov ntev ntawm cov plag tsev yog txiav txim siab los ntawm lawv), yog tsim los so ntawm ob lossis peb sab.
Alphanumeric pawg hauv qib muaj cov npe tsim nyog hauv qab no: chav kawm ntawm prestressed reinforcing steel, bearing peev xwm, hom pob zeb, slab loj thiab muaj qhov ntawm ib txhiab, xya puas lossis plaub puas millimeters (tsim 3, 2, 1 li).
Cov khoom siv 12 yog qhov xav tau tshaj plaws hauv kev tsim vaj tsev - PC floor slabs nrog qhov dav ntawm ib txhiab ob puas millimeters. Kev nruj nruj raws li cov kev cai ntawm cov qauv thiab cov ntaub ntawv hauv qhov project txiav txim siab ntxiv kev nyab xeeb ntawm lub tsev tag nrho.
