Hollow-core slabs: kev piav qhia thiab cov duab

Ib tug ntawm cov yooj yim tshaj plaws, pheej yig thiab yooj yim kom dhos rau cov ntaub ntawv yog slabs rau plag tsev. Lub ob hom ntawm cov khoom yog tam sim no ua: hollow thiab full-bodied. Txhua yam yog tsim los daws tau tej kev tsim kho kev pab raws qib, tsis tau ntau ntau nyob rau hauv qhov kev siv ntawm ntau yam lug ntawm hollow-core slabs yog siv. Nyob rau hauv qhov tseeb, qhov no ntau yam tsim, vim hais tias lawv muaj peev xwm yuav siv tau rau txhua yam uas kev tsim kho. Lawv yog cov tseem ceeb nyob rau hauv yug me nyuam cov plag tsev, qab daus compartment los ntawm lub ntsiab vaj tse, kev tsim kho ntawm garages, ru tsev thiab ntau lwm cov chaw.

Phiaj overlap (PC) - ib tug ca pob zeb ua thaiv lub. Hauv cov qauv, muaj dawb kab noj hniav. Lawv yuav tsum txo tus luj ntawm lub vaj huam sib luag, kom nws teplosohranyayuschie zog. Hauv lub muaj kab noj hniav yuav ua tau cov nqi vaj tse yog tias tsim nyog.

ntau lawm nta

panels ntau lawm yuav siv sij hawm qhov chaw nyob rau hauv peb tes num drawings los ntawm sau nyob rau hauv raws li GOST: hollow-core slabs no yog ua los ntawm hnyav qhob chav kawm ntawv ceev no yog tsis tsawg tshaj li B30. Los xyuas kom meej qhov tsim nyog lub dag lub zog cov khoom, lub formwork yog muab tso rau hauv tus ncej. Cas sim haum lub neej thiab khaws cia rau lub zog ntawm tag nrho cov ntsiab ntawm cov hlau loj rau kev tiv thaiv tiv thaiv xeb ntawm ib tug tshwj xeeb pes tsawg leeg. Nrog cov yam khoom no nyob twj ywm zoo FLEXURAL zog rau decades.

Nyob rau hauv tas li ntawd, raws li GOST, rau panels uas yuav kos rau ntawm phab ntsa nrog tsuas yog ob tug los yog peb ob tog, tus ncej yog ua tsis yog los ntawm ib tug yooj yim cuab lub zog thiab prestressing.

Yuav kom ntxiv pab txhawb lub chaw ua hauj lwm nrog cov xov cov ntaub ntawv, lub Upper thiab qis dav hlau ntawm lub panels ua tib zoo mus raws li lub, yog li ntawd lawv yuav tsis ua ntawv thov cov plastering yuav pleev xim rau, dai wallpaper, siv lwm yam xov cov ntaub ntawv. Khi-down qhov thiab kos pob khawm panels yog tsim rau ib qho yooj yim mounting thiab zog.

txoj kev siv thiab ua

Tag nrho lawm txheej txheem yog nruj me ntsis tshuaj thiab tswj raws li cov kev cai ntawm cov ntaub ntawv. Raug cov khoom uas yuav siv sij hawm qhov chaw raws li nram no: ib tug tshwj xeeb daim ntawv uas muaj qhib rau hom kev txhawb ntawm 3-5 cm los ntawm cov ntug ntawm tus ncej qauv.

Ua ke nrog lub cev raug nteg thiab strapping voj. Thaum ib tug nws yog xim hlau qhov cuab lub zog yog npaj, lub sib tov yog poured nrog qhob. Tsaug rau qhov kev siv ntawm cov qauv ntawm cov kev co khoom uas muaj tau tsis tsuas check, high-zog, tab sis kuj nruj me ntsis raws li tsim tsis. Lawv tsis muaj burls, tej kab nrib pleb, kab noj hniav, daim tawv nyias thiab lwm yam tsis xws luag uas muaj peev xwm txo lub dag lub zog ntawm cov khoom.

Lub panels tau ces raug thermal kho mob thiab xa mus rau hauv txoj kev kuaj, qhov twg lawv kis tau soj ntsuam kuaj cov kev kuaj kom paub tias tsis xws luag thiab soj ntsuam thiab lub hom phiaj tseem ceeb.

ntaub ntawv

Mus rau yav tom ntej ntawm sib tshooj phaj muaj qhov tsim nyog yam ntxwv rau lawv siv thiab ua, tsuas yog lim dej manufacturers siv xwb zoo Portland cements. Me feem muab tub lim yog xuab zeb thiab gravel rubble. Lawv yog cov resistant mus kub thiab sib tham cov zog cov vaj huam sib luag. Yuav kom maximize lwm yam tseem ceeb indicators, As, ntau yam plasticizers.

Kev nruam reinforcing nyob rau hauv lub npaj khoom tej zaum yuav siv tau:

1. Semiprovolochnye strand seem 6n-7.
2. Ib tug high-zog hlau periodic profile. Nws tus ntoo khaub lig seem yuav tsum 5Vr-II.
3. Cov rods, uas yog siv rau qhov siv thiab ib tug thermally tawv steel Ar-V chav kawm ntawv.
4. Ropes nrog ib lub cheeb ntawm 6 hli chav kawm ntawv K-7.
5. Reinforcing hlau Bp chav kawm ntawv-II thiab lwm yam zoo xws ntaub ntawv tso cai Gosstandard.

qauv ntsuas

Hollow-core slab 1 Series 1141 - yog ib tug loj siv thiab ua cov Vaj Huam Sib Luag PC txheem. Yog li ntawd, nyob rau hauv qhuav ntawm nruj raws li nrog tag nrho cov kev cai thiab cov kev tswj. Ntxiv mus, lub vaj huam sib luag yeej tsis lom rau kev siv yog hais tias lawv tsis muaj lub zoo kos, raws li evidenced los ntawm sau npe daim ntawv pov thawj xa tuaj rau nws thiab daim ntawv pov.

Raws li cov applied cov ntaub ntawv, xaiv yam khoom rau ib tug kwv nrog cov yam ntxwv ntawm vaj huam sib luag cov khoom thiab cov kev kawm uas yuav tsum tau.

npav

Txij li thaum lub hollow-core pem teb slabs yog tsim los rau cov hom kev tsim kho, thaum lub sij hawm manufacture lawv tus cim. Ua li no, yuav cim nyob rau hauv daim ntawv ntawm cov tsiaj ntawv thiab ua zauv:

1. PC - hollow-core slab.
2. Thawj cov signage - ntev. Sawv cev nyob rau hauv decimeters (daim duab npawv rau ib tug integer).
3. Qhov thib ob daim duab nruab nrab yog ib tug dav nyob rau hauv dm (tus nqi npawv).
4. Qhov thib peb daim duab nruab nrab yog ib tug tshaj plaws Performance index kev coj tus kheej thaj chaw ntawm cov khoom. Qhov taw qhia xwm nyob rau hauv MPa.

yam ntxwv ntawm

Tam sim no ua ntau hom ntawm hollow khoom, uas sib txawv raws li lub cheeb thiab zoo ntawm lub voids daim hlau rau lawv tus kheej. Ib tug ntawm cov ntsuas uas tus hollow-core slabs txawv - Qhov ntau thiab tsawg.

Siv lub vaj huam sib luag rau lub tsev yuav ua tau tej yam ntxwv qhov ntev: zuag qhia tag nrho kev kawm yog li ntawd unified tias tag nrho cov haum. Qhov no yog ib tug ntawm cov tseem ceeb cov yam ntxwv ntawm cov khoom, uas yog qhov no series. Hollow-core slabs mas hnyav loads, lawv yog ua tsis tau zoo rau qhov luaj li cas ntawm cov khoom, uas yog npaj rau kev siv nyob rau hauv kev tsim kho ntawm lub hauv paus, load-tau cov kabmob phab ntsa. Tab sis nyob rau tib lub vaj huam sib luag qauv nrog voids muaj ib tug ntau yam muaj kev ruaj ntseg tau.

Ntsiab zog

Yuav kom to taub li cas tseem ceeb thiab tsim nyog rau qhov kev siv ntawm vaj huam sib luag designs yog txaus los mus tshawb qhov zoo uas ua kev reinforced hollow-core slabs. Series 1 141 1 npaj rau kev siv nyob rau hauv qhov chaw ntawm siab seismic yam kev ua si, yog li ntawd, yog tshwj xeeb yog durability. Nyob rau hauv tas li ntawd, cov kev siv ntawm cov khoom, thiab muaj ntau yam lwm yam zoo:

1. Cia lug rau withstand es impressive load.
2. Hollow khoom muab thermal rwb thaiv tsev zog, zoo heev kuj mus te thiab hluav taws.
3. Nrog kom haum ntawm lub overlap phaj txhawb muab tsis kab rov tav nto.
4. Yuav txhim khu te ua vaj huam sib luag, nyob rau hauv uas cov kab noj hniav uas muaj cov ntxeem tau rwb thaiv tsev ntaub.
5. Fabrics yog check, ntxiv kho mob uas tsis tsim nyog, lawv siv considerably tswj hauv daim ntawv thov ntawm cov topcoat.
6. Siv daim hlau pab txoj kev watertightness ntawm lub tsev, kev tiv thaiv lub nkag mus ntawm roj nyob rau hauv lwm qhov chaw ntawm cov vaj tse, chav, raws li zoo raws li cov suab nrov.

Nta ntawm daim ntawv thov
