Cov qauv rau cov cuab yeej sib tshooj ntawm cov plag tsev ntawm lub tsev nyob rau hauv kev tsim kho yog cov khoom siv pob zeb ntxiv. Lawv yog tsim los ntawm kev sib xyaw ua ke los ntawm ntau qib hnyav, lub teeb hom qauv pob zeb nrog cov qauv ntom ntom, nrog rau los ntawm cov pob zeb uas muaj zog silicate. Hauv pem teb slab pom nws daim ntawv thov tseem ceeb hauv kev tsim kho ntawm cov kabmob ntawm cov kab rov tav ntawm cov vaj huam sib luag loj. Lub payload ntawm cov khoom yuav tsum tsis txhob ntau tshaj li cov cai ntawm 6 kPa, thaum lub luj ntawm tus qauv tsis muab rau hauv tus account. Hollow core slabs yuav tsum tau muab tso rau ntawm lub hauv paus (phab ntsa) ntawm qhov deb ntawm tsawg kawg yog 150-200 mm, yog tias qhov kev txhawb nqa muaj zog dua li cov khoom nws tus kheej.
Ntawm cov qauv tseem ceeb ntawm kev tsim hauv pem teb yog cov hauv qab no:
- PPS - txiav cov pob zeb ua pob zeb;
- ribbed lossis nrog trough profile;
- hollow (ntau-hollow);
- monolithic.
Kev kos ntawm hollow core slabs txhais tau tias cov hauv qab no:
- 1P - pob zeb ib txheej txheej nrog qhov siab ntawm 120 hli;
- 2P - tib lub phaj, tab sis tuab dua (160 mm);
- 1pc -multi-hollow (220 mm), nyob rau hauv uas muaj ib puag ncig voids nrog ib txoj kab uas hla ntawm 159 mm;
- 2pcs - tib lub phaj, kab noj hniav txoj kab uas hla - 140mm;
- PB - ntau qhov hollow nrog qhov siab ntawm 220 mm, txoj kev tsim - tsis siv cov formwork.
Hollow core slabs, nws qhov ntev yog nyob rau hauv cov qauv txwv, tseem yog ib qho ntawm cov ntsiab lus yooj yim tshaj plaws. Lawv tsis ignite, tsis rot, yog heev ruaj thiab txhim khu kev qha, thiab resistant rau ya raws.
Qhov ntev ntawm cov slabs hauv pem teb muaj qhov tsis sib xws ntawm parallelepiped, sab hauv uas muaj cov voids nyob rau hauv daim ntawv ntawm cov kav dej cylindrical. Lub xub ntiag ntawm cov ntim khoom no muab cov qauv ntawm cov cuab yeej khoov rigidity, uas ua rau nws muaj peev xwm tiv taus qhov hnyav hnyav. Ntxiv mus, voids pab tau zoo heev rau cov txheej txheem ntawm kev tso tag nrho cov kev sib txuas lus nyob rau hauv lawv thaum lub sij hawm tsim lub tsev.
Txheem tag nrho qhov ntev ntawm cov slabs hauv pem teb yog cov khoom lav ntawm cov nqi tsim nyog ntawm cov khoom siv pob zeb. Txawm li cas los xij, cov qauv nrog qhov ntev sab nraud tuaj yeem tsim tau raws li tus neeg kos duab. Txawm hais tias nws yog qhov zoo dua rau cov neeg tsim khoom lag luam los txiav txim siab txog kev siv cov qauv ntau thiab tsawg vim tias tus nqi siab dua ntawm kev tsim cov slabs uas tsis yog tus qauv tsim los ntawm cov nqi ntxiv.
Qhov ntev ntawm cov slabs hauv pem teb nrog voids thaj tsam ntawm 2.4 txog 6.6 m nyob rau hauv ntev, uas nyob ntawm cov catalog nrog ib tug series rau ib yam khoom. Qhov dav li ib txwm tuaj yeem yog 0.6 - 2.4 m ntawm qhov sib txawv nrog cov kauj ruam sib txawv. Qhov siab(thickness) ntawm daim hlau yog nyob rau theem ntawm 220 hli, thiab tag nrho qhov hnyav ntawm tag nrho cov khoom yog txog 2.5 tons.
Dimensions ntawm hollow core floor slabs PC yog encrypted nyob rau hauv lub cim ntawm txhua yam khoom, thiab lawv yuav tsum to taub nyob rau hauv no txoj kev, piv txwv li, PC 72.15-8:
- PC txhais tau tias cov hauv qab no: hollow core slab nrog puag ncig kab noj hniav 159 mm inch, siab tshaj plaws 220 mm, ob sab yog npaj los txhawb;
- 72 - cov khoom ntev hauv decimeters (uas yog, hauv millimeters - 7180);
- 15 - dav hauv decimeters (los yog xam 1500 mm);
- 8 yog lub nra uas lub slab tuaj yeem tiv taus, hauv kPa.
