Standard ntau thiab tsawg slabs

Designs rau kaw pab kiag li lawm ntawm cov plag tsev ntawm lub tsev nyob rau hauv kev tsim kho - nws yog ua kev reinforced. Lawv yog ua los nrog lub pob zeb admixtures ntawm ib tug xov tooj ntawm hnyav qib, khaub-ncaws nyias yam ntxwv qhob hom tuab qauv, raws li tau zoo raws li kev reinforced silicate. Lub ntsiab kev siv pem teb slab yog nyob rau hauv kev tsim kho ntawm lub txhawb ib feem ntawm lub kab rov tav dav hlau ntawm loj vaj tse. Lub payload rau cov khoom yuav tsum tsis txhob ntau tshaj 6 kPa tshuaj ntsuam, thaum tus luj ntawm lub qauv yog tsis suav hais tias. Stacking ntawm hollow tub ntxhais slabs yuav tsum tau ua nyob rau hauv lub hauv paus (phab ntsa) ntawm ib tug deb ntawm tsawg kawg yog 150-200 hli muab nco ntsoov tias cov nyiaj them yug yog tus muaj zog tshaj cov khoom nws tus kheej.

Ntawm cov ntsiab hom lug rau cov tsim ntawm sib tshooj yog cov nram qab no:

• PPP - threaded qhob slabs;
• los yog Korytnyi ribbed profile;
• hollow (hollow ntxhais);
• monolithic.

Npav hollow tub ntxhais txhais tau tias cov nram qab no:

• 1h - qhob ib leeg-txheej qauv nrog ib tug qhov siab ntawm 120 hli;
• 2P - tib yam ntau yam, tab sis ntawm ntau dua thickness (160 hli);
• 1CO - hollow tub ntxhais (220 hli), hauv uas muaj cov voids nrog ib puag ncig txoj kab uas hla 159 hli;
• 2CO - tib yam phaj, lub lub cheeb ntawm lub kab noj hniav - 140 hli;
• PB - hollow tseem ceeb nrog ib tug qhov siab ntawm 220 hli, ntawm txoj kev txoj kev - tsis muaj formwork.

hollow tub ntxhais slabs uas nws qhov ntev muaj nyob rau hauv tus txheej txheem, tseem yog ib lub yooj yim tshaj plaws siv cov ntsiab lus. Lawv tsis raug mus rau hluav taws kub, yuav tsis rot, yog cov tsis tshua check thiab txhim khu kev qha, resistant rau dej.

Qhov ntev slabs muaj qhov tsis muaj ib tug parallelepiped, hauv uas muaj cov voids nyob rau hauv daim ntawv ntawm cylindrical menyuam. Lub xub ntiag ntawm cov hlab ntsha muab tus tsim nruj nyob rau hauv dabtsi yog khoov vaj tse, uas yuav ua rau nws tau mus rau extract hnyav loads. Ntxiv mus, lub voids heev pab txhawb cov txheej txheem ntawm tso hauv lawv tag nrho cov tau kev sib txuas lus thaum lub sij hawm tsim kho ntawm lub tsev.

Standard qhov ntev ntawm slabs - ib tug khoom guarantee kom txaus tus nqi ntawm qhob khoom. Txawm li cas los, tus tsim nrog qhov ntev tshaj li ib txwm muaj peev xwm yuav tsim raws li ib tug neeg kos duab. Txawm tias yig tsim kom zoo dua muab rau hauv daim ntawv thov ntawm normative ntau thiab tsawg pab vim tus nqi kom siab ntawm cov raug kev uas tsis yog-tus qauv daim hlau raws li ib tug tshwm sim ntawm ib co nqi ntxiv.

Raug qhov ntev ntawm slabs nrog voids roos nyob rau hauv ntev rau hauv lub chav 2.4 rau 6.6 m, nyob ntawm seb lub directory rau ib tug raug series cov khoom. Li ib txwm dav tej zaum yuav 0.6 - 2.4 m nyob rau hauv cov Team sib ntawm ib tug txawv suab. Lub qhov siab (thickness) daim hlau coj nyob rau theem ntawm 220 hli, thiab tag nrho cov luj ntawm tag nrho cov khoom mus txog 2.5 tonnes.

Qhov ntev slabs hollow-hom PC yog encrypted nyob rau hauv lub labeling ntawm txhua yam khoom, thiab kom to taub lawv mus yuav li ntawd, piv txwv li, ib tug PC 72.15-8:

• PC txhais tau tias cov nram qab no: hollow-core slab nrog puag ncig kab noj hniav nrog txoj kab uas hla ntawm 159 hli, 220 hli siab tsis pub tshaj, ob tog yuav tsum tug ncej;
• 72 - ntev nyob rau hauv decimeters product (i.e., nyob rau hauv millimeters - 7180);
• 15 - dav nyob rau hauv decimeters (los yog tus xam 1500 hli);
• 8 - load ntawd mas lub qhov cub, nyob rau hauv kPa.
