Npav
Pem teb slabs yog kab rov tav cov ntsiab lus ntawm ib lub tsev uas sib faib ua qhov chaw rau hauv pem teb. Ntxiv nrog rau kev ua haujlwm hnyav, cov pob zeb no yog ib feem ntawm "pob txha pob txha" ntawm tus qauv, lub luag haujlwm rau kev nruj ntawm tag nrho lub tsev. Lawv yog ua los ntawm kev ua vaj tse, yog li ntawd, lawv muaj tus lej zoo: muaj zog, ruaj khov, tiv taus hluav taws, tiv taus huab cua . Qhov tsis zoo suav nrog: kuj loj, muaj tus kheej kev nyuab siab, siab kub thiab ua kom muaj suab nrov.
Txhawm rau ua kom yooj yim tsim thiab tsim kho, qhov ntev ntawm cov plag tsev tau coj mus rau qee tus qauv. Tam sim no tus tsim tawm tsis tas yuav paub txhua qhov nyuaj ntawm kev siv thev naus laus zis, nws txaus los tuaj yeem txiav txim siab qhov cim. Npav txhais tau tias encrypted cov ntaub ntawv hais txog qhov ntev, lub zog tseem ceeb thiab cov qauv ntsuas.
Nws tau ua tiav raws li GOST 23009 thiab tau muab faib ua 3 pawg, uas tau muab cais los ntawm ib tus hyphen . Thawj pab pawg suav nrog cov ntaub ntawv ntawm hom vaj huam sib luag, hauv cov yam ntxwv geometric thib ob (ntev / dav). Hauv pab pawg thib peb, cov ntsuas ntsuas lub zog, chav kawm ntawm cov hlau txhawb nqa thiab hom pob zeb ua haujlwm tau qhia. Cia peb txheeb xyuas qhov kev txiav txim siab ntawm PC-48.12-8At-V-t, qhov twg:
- PC - hollow vaj huam sib luag;
- 48 - ntev 48 dm (4.8 m);
- 12 - dav 12 dm (1,2 m);
- 8 - rau kev faib khoom sib luag ntawm 800 kg ib m2;
- At-V-txhawb kev txhawb zog (chav kawm At-V);
- t - hom pob zeb hnyav.
Lub qhov siab 220 hli tsis tau qhia, vim nws yog tus qauv rau hom khoom no. Nyob ntawm tus txheej txheem ntawm kev tsim khoom, cov slabs tau muab faib ua:
- prefabricated (lub Hoobkas);
- monolithic.
Qhov kawg yog ua ncaj qha rau ntawm qhov chaw tsim kho.
Cov txheej txheem suav nrog kev sib sau cov ntawv ua haujlwm, kev txhim kho cov nyom thiab cov ntxaij vab tshaus, tso pob zeb thiab rhuav tshem cov ntawv ua haujlwm. Raws li kev tsim qauv daws teeb meem, kev txhawb cov pob zeb ua haujlwm tau zoo li no.
Khoom (tag nrho lub cev) . Lub vaj huam sib luag yog tiaj, nrog lub zog siab, suab qis thiab rwb thaiv tsev cua sov. Yooj yim txaus los tsim khoom, tab sis cov khoom siv ntau dua. Lawv muaj qhov hnyav hnyav (600-1500 kg) nrog qhov loj me. Feem ntau lawv siv los ua cov plag tsev ntawm cov tsev siab.
Ribbed (U-puab vaj huam sib luag) . Lawv cov yam ntxwv tshwj xeeb yog nyob rau hauv kev hloov pauv ntawm cov tuab thiab cov khoom me me, vim qhov tsim nyog khoov ruaj khov tau ua tiav. Lawv feem ntau siv hauv kev tsim cov qauv kev lag luam, txij li kev tsim vaj tsev nyob qhov kev teeb tsa no nyuaj ua kom tiav. (P2)
Hollow . Lawv yog hom khoom siv ntau tshaj plaws ntawm cov khoom siv ua vaj tse. Lawv sawv cev rau qhov sib luag nrog cov thooj voos kheej kheej, ua tsaug rau qhov slab ua haujlwm tau zoo rau khoov lub sijhawm, tiv taus lub nra hnyav, tso cai rau txuas cov kab loj (mus txog 12 meters), thiab pab txhawb kev sib txuas lus.
PC - Hom nrov tshaj plaws ntawm cov pob zeb ua tiav hauv tsev, sab hauv muaj qhov taub nrog 140 mm thiab 159 mm, tuab ntawm cov khoom yog 220 mm.
NPE - tus qauv txhim kho nrog qhov tuab me dua ntawm 160 mm. Nws tuaj yeem tiv taus lub nra hnyav vim yog cov khoom txhawb kom tuab. Nyuaj dua cov qauv hollow-core qauv, yog li qhov kev xaiv no yog kev lag luam ntau dua.
PPS (nthuav polystyrene, BP) - lub rooj ntev zaum, ntawm lub cim tshiab, yog tsim los ntawm cov txheej txheem tsis muaj txheej txheem, uas tso cai rau tus tsim tawm siv nws tus kheej qhov ntev. Qhov poob qis ntawm no yog tus nqi siab.
Txuj ntau thiab tsawg
Txheem qhov ntev ntawm cov pob zeb tau teev tseg hauv GOST 9561-91. Peb yuav nthuav qhia lawv hauv daim ntawv ntawm lub rooj.

Qhov hnyav yog ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws. Ntxiv nrog rau kev suav cov khoom faib khoom, nws yuav txiav txim siab yuav ua li cas slab yuav xa mus rau qhov chaw tsim kho thiab teeb tsa. Txog qhov no, qhov peev xwm nqa ntawm crane tau suav. Kev teeb tsa, raws li txoj cai, yog nqa los ntawm lub tsheb thauj khoom uas muaj peev xwm nqa tau yam tsawg kawg nkaus ntawm 5 tons.
Qhov ntau ntawm cov khoom hnyav hauv Russia txawv ntawm 960 kg txog 4, 82 tons.

Yuav suav li cas kom raug?
Thaum pib, nws yog qhov yuav tsum tau ua kom raug cov slabs ntawm txoj kev npaj. Txoj cai yooj yim: cov pob zeb hauv pem teb tau txais kev txhawb nqa tsuas yog ntawm ob sab . Txij li cov slab muaj qhov ua haujlwm txhawb nqa qis dua, kev thauj khoom hauv zos (tshaj tawm, kab ntawv) yuav tsum tsis raug tso cai . Lub ntsiab lus tseem ceeb yuav nyob ntawm cov phab ntsa hauv pem teb yuav ua raws (phab ntsa ua los ntawm cov qhob cib, cib, pob zeb ua ke), uas cuam tshuam rau kev suav ntawm cov khoom thauj.
Txiav txim siab kwv yees qhov ntev ntawm qhov slab . Nws me dua qhov tiag thiab yog qhov nruab nrab ntawm cov phab ntsa uas nyob deb tshaj plaws. Nws tau teeb tsa los ntawm cov duab geometric. Cov kauj ruam tom ntej yog khaws cov khoom thauj. Txhawm rau txiav txim siab lub nra ntawm txhua yam khoom, nws yog qhov tsim nyog los qhia ntawm txoj kev npaj txhua qhov hnyav ua rau hauv pem teb.
Qhov no suav nrog: xuab zeb-cement screeds, rwb thaiv tsev cua sov, npog hauv pem teb, muab faib ua ke.
Thaum suav cov khoom no, koj yuav tsum faib cov txiaj ntsig los ntawm tus lej ntawm cov phaj. Yog li, qhov kev tso cai siab tshaj plaws rau txhua qhov khoom tuaj yeem tau txais.
Lawm, nws tsis tuaj yeem thauj lub tsev thav duab kom ntau li ntau tau kom tsis txhob mus txog qib tseem ceeb, rau qhov no qhov txiaj ntsig zoo yog xam . Piv txwv li, slab hnyav 2400 kg, nws tau npaj rau thaj tsam ntawm 10 m2. Nws yog qhov tsim nyog los faib 2400 los ntawm 10. Nws hloov tawm tias qhov siab tshaj plaws tso cai yog 240 kg rau 1 m2. Qhov hnyav ntawm cov khoom nws tus kheej, uas lub load tau xam, yuav tsum raug coj mus rau hauv tus account (xav tias nws tus nqi yog 800 kg rau 1 m2). Tom qab ntawd nws yog qhov yuav tsum tau txiav tawm 240 los ntawm 800, uas muab qhov ntsuas ntawm 560 kg rau 1 m2.
Cov kauj ruam tom ntej yog kwv yees kwv yees qhov hnyav ntawm txhua qhov khoom thauj khoom . Cia peb hais tias nws sib npaug 200 kg rau m2, tom qab ntawd peb rho 200 kg ib m2 los ntawm peb qhov ntsuas yav dhau los ntawm 560 kg rau m2 thiab peb tau 360 kg rau m2. Kauj ruam kawg yog txiav txim siab qhov hnyav ntawm tib neeg, ua tiav cov ntaub ntawv, rooj tog zaum. Qhov nruab nrab, qhov no yog 150 kg ib m2. Tom qab ntawd koj yuav tsum rho 150 tawm ntawm 360. Peb tau txais kev pom zoo ntawm 210 kg ib m2. Lub sijhawm khoov siab tshaj plaws tuaj yeem suav nrog siv cov mis: Mmax = q * l ^ 2/8, qhov twg l yog qhov ntev ncua.
Hauv qib tom ntej chav kawm ntawm cov pob zeb ua ke thiab ntu ntu ntawm qhov txhawb nqa raug xaiv raws li cov khoom sib txawv … Kauj ruam kawg yog tshuaj xyuas cov xeev txwv.
Teeb duab 1. Cov txheej txheem ntawm slabs hauv vaj huam sib luag tsev.
Teeb duab 2. Lub tsev ntiag tug.
Teeb duab 3. Lub tsev ntau lub tsev.
