Kev txhim kho hauv pem teb slabs yog ib theem kev tsim kho thev naus laus zis, uas muaj ntau yam tseem ceeb. Yog tsis muaj lawv txoj kev paub, cov neeg tsim khoom tuaj yeem ua yuam kev ntau, ua rau muaj qhov tshwm sim loj.
Hom khoom thiab cov yam ntxwv ntawm lawv xaiv
Hnub no, ob hom khoom zoo sib xws tau tsim - hollow thiab monolithic. Txhua tus ntawm lawv muaj nws tus kheej qhov tsis zoo thiab qhov zoo, coj mus rau hauv tus account uas nws yog qhov tsim nyog los xaiv cov qauv tsim rau ib qho qauv. Yog li, yog tias lub tsev me me, cov khoom lag luam monolithic tsis haum rau nws vim nws qhov hnyav dhau lawm, uas yuav ua rau nyuaj rau kev teeb tsa hauv pem teb slabs. Tsis tas li ntawd, cov qauv monolithic muaj qhov tsis muaj suab nrov thiab txuag hluav taws xob, yog li lawv tsis tshua siv rau hauv kev tsim vaj tsev nyob, tab sis hauv kev tsim kho vaj tse thiab pej xeem cov chaw, cov qauv no yog qhov tseem ceeb.
Hollow cov khoom tseem ceeb muaj nuj nqis rau lawv cov txiaj ntsig tseem ceeb: tus nqi qis dua thiab sib dua. Tab sis txawm hais tias cov qauv tsim muaj qhov qis dua hauv kev sib piv nrog cov khoom siv tag nrho, kev thauj mus los thiab kev teeb tsa ntawm daim hlau.overlapping tsuas yog ua tau siv cov cuab yeej tshwj xeeb.
Ntawm ntawm qhov webs
Cov txiaj ntsig ntawm kev siv cov hollow core slabs suav nrog txo cov khoom thauj ntawm lub hauv paus thiab phab ntsa ntawm cov tsev. Ntxiv mus, qhov no ua tau txawm hais tias qhov kev teeb tsa ntawm qhov tsis muaj dab tsi, uas yog puag ncig, polygonal lossis oval.
Tswv yim: Hollows tuaj yeem siv rau cov kav dej corrugated, thawv yas lossis cable ducts.
Yog li, kev teeb tsa ntawm precast pem teb slabs yog qhov lav:
- zoo suab thiab rwb thaiv tsev zoo.
- Durability.
- High mechanical density.
- Hluav taws kub resistant - cov kab noj hniav sab hauv tiv thaiv tshav kub los ntawm kev igniting ntoo thiab yas ntsiab los ntawm kev nkag mus ntxiv.
Kev cuam tshuam ntawm qhov loj me ntawm lawv qhov kev teeb tsa
Tam sim no, canvases yog tsim nrog lub thickness ntawm 22 cm, ntev ntawm 1.8 mus rau 6.3 m thiab dav ntawm 0.99 mus rau 1.49 m. Qhov hnyav ntawm cov qauv nyob ntawm qhov loj thiab hom (monolithic lossis hollow). Raws li, qhov nyuaj ntawm mounting ib tug monolithic pem teb slab yog siab tshaj li ntawm ib tug hollow qauv ntawm zoo sib xws qhov ntev.
Muaj ob peb lub ntsiab lus tseem ceeb ntxiv uas koj yuav tsum tau ua tib zoo saib ua ntej yuav cov khoom ua vaj tse. Koj yuav tsum ua raws li qhov no:
- Cov qauv tsim tau ze rau lub ntsej muag tus nqi li sai tau.
- Cov khoom saum npoo ntawm cov khoom yuav tsum tsis txhob muaj kev nyuaj siab, bulges, tawg, nrog rau cov kab greasy lossis xeb.
- Designs muaj qhov tsim nyogdaim ntawv pov thawj zoo.
Ua ntej koj pib
Muaj ntau ntau txoj cai tseem ceeb rau kev teeb tsa hauv pem teb slabs uas cov kws tsim khoom paub zoo txog. Cov neeg tsim khoom ntiag tug tej zaum yuav tsis paub txog qhov no, feem, ib qho kev hais ntxiv yuav tsis yog superfluous:
- Ntawm cov khoom kom lawv sab du yog tig, thiab sab ntxhib nce.
- Nyob rau hauv cov canvases raws lawv qab.
- Slabs muab tso ze rau ib leeg, tsis muaj qhov khoob.
- Txoj cai tseem ceeb rau kev teeb tsa hauv pem teb slabs yog cov khoom yuav tsum tau muab tso rau kom lawv so nrog lawv luv luv ntawm cov kabmob phab ntsa. Ntev sab tsis pom zoo rau kev txhim kho phab ntsa.
- Cov kev pabcuam tshwj xeeb yog kim, yog li yuav tsum tau npaj txhua yam tsim nyog rau kev ua haujlwm ua ntej, suav nrog kev caw 2-3 tus pabcuam kom lub installation ceev thiab du.
Ceeb toom: ua ntej pib ua haujlwm ntxhib, nws yuav tsum tau sau, kom deb li deb tau, cov voids hauv canvases nrog nthuav av nplaum.
Npaj rau kev teeb tsa ua haujlwm
Ua ntej tshaj plaws, nws yog ib qho tsim nyog yuav tsum tau ua kom cov phab ntsa thauj khoom kom lawv nyob li qhov siab. Qhov sib txawv ntawm lawv qhov chaw tuaj yeem tsis ntau tshaj 1 cm.
Yuav kom paub seb qhov chaw tiaj tus li cas, koj tuaj yeem siv lub nqaj tsis tu ncua. Qhov tseeb ntawm qhov tshwm sim nyob ntawm qhov ntev ntawm lub nqaj - qhov luv dua, qhov tsawg dua qhov tshwm sim yuav yog. Siv cov nqaj ua ib theem ntawm lub tsev, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas tag nrho cov phab ntsa uas yuav siv los ua kev txhawb nqa rau cov slabs. Yog tias muaj qhov tsis xwm yeem tshwm sim, lub npe raug siv rau ntawm phab ntsa hauv qhov chaw no.
Tom qab ntawd, txiav txim siab qhov siab tshaj plaws thiab qis tshaj. Raws li cov ntaub ntawv tau txais, theem yog nqa tawm los ntawm kev sib xyaw ua ke thiab cov hlau mesh.
Ib qho tseem ceeb: thaum npaj cov mortar, koj yuav tsum tau ceev faj heev thiab ua tib zoo sift cov xuab zeb thiab cov cement kom tsis txhob muaj ib lub pob zeb nkag mus rau hauv - txwv tsis pub cov slab yuav pw tsis raug thiab lub qab nthab yuav tsis sib xws.
Yog tias cov phab ntsa ntawm lub tsev tau tsim los ntawm cov pa roj silicate, slag lossis ua npuas ncauj ua npuas ncauj, lawv yuav tsum tau ntxiv dag zog. Rau lub hom phiaj no, koj tuaj yeem siv txoj siv hlua khi nrog qhov siab tsawg kawg yog 0.15 m. Ua tsaug rau qhov no, nws yuav ua tau kom tsis txhob muaj qhov deformation ntawm cov phab ntsa thiab tiv thaiv hauv pem teb los ntawm kev tawg.
Npaj qhov chaw rau lub crane
Lo lus nug no yog ib qho ntawm cov theem tseem ceeb hauv kev npaj rau kev teeb tsa hauv pem teb slabs thiab txheej txheej: qhov zoo ntawm kev teeb tsa ntawm cov canvases thiab txawm tias kev ncaj ncees ntawm ob lub tsev nyob hauv kev tsim kho thiab cov tsev nyob ze, nrog rau kev nyab xeeb, nyob ntawm seb yuav ua li cas thiaj ua tau haujlwm raug. Txhawm rau txhawm rau txhim kho lub crane kom ruaj ntseg, nws raug tso cai rau nruab nws tsuas yog hauv cov av compacted. Nyob ze yuav tsum tsis txhob muaj tsev nyob rau hauv kev tsim kho nrog hauv qab daus - kev txhawb nqa ntawm cov cuab yeej tshwj xeeb thaum lub sijhawm ua haujlwm tsim cov khoom loj ntawm cov av, uas cov phab ntsa hauv qab daus yuav tsis tiv taus.
Yog av ntawm qhov chawbulk los yog xoob, nws yog ib qho tsim nyog yuav tau xauj ib lub crane nrog qhov ntev tshaj plaws boom - ces nws yuav ua tau rau nruab cov khoom siv ntxiv, qhov twg lub zog ntawm cov av tsis muaj kev txhawj xeeb. Yog tias kev tsim kho yuav tsum tau ua nyob rau lub caij nplooj zeeg lossis caij nplooj ntoos hlav, thaum av saturated nrog noo noo, kom cov khoom tshwj xeeb tsis tau bogged hauv slush, lawv npaj qhov chaw rau nws installation ua ntej los ntawm nteg tawm cov av nto nrog txoj kev slabs..
Kev ua slab hauv ob sab
Tso ib lub slab rau ob qhov ntev tsis pom zoo - nws tuaj yeem tawg, tab sis yog tias koj yuav tsum ua li ntawd, txhawm rau kom tsis txhob muaj kev puas tsuaj thaum lub tsev shrinkage tiv thaiv lub hauv paus ntawm nruab nrab phab ntsa, koj yuav tsum tau ua ib qho incision ntawm lub slab siv lub grinder nrog lub pob zeb diamond disk. Qhov tob ntawm qhov txiav yog mus rau qhov tob ntawm lub disc. Tom qab ntawd, yog tias qhov tawg tshwm sim, nws yuav mus raws qhov ntsuas siab - thiab qhov no yog qhov tau txais.
Qee zaus, txhawm rau kom haum cov phiaj xwm rau qhov xav tau, lawv yuav tsum tau ua kab ntev lossis dav. Txhawm rau ua haujlwm, siv cov cuab yeej hauv qab no:
- Qab.
- sledgehammer.
- Bulgarian. Lub pob zeb diamond disc tau nruab rau ntawm lub cuab yeej rau kev ua haujlwm.
- Ib lub rooj tsavxwm lossis ntoo uas yuav muab tso rau hauv qab daim ntaub hauv qab kab ntawm kev txiav yav tom ntej.
Txhim daim phiaj rau qhov loj
Ua ntej tshaj, nyob rau saum npoo ntawm daim ntaub, cov cim tau ua thiab txiav yog ua nrog lub tshuab sib tsoo. Tom qab ntawd lawv ntaus nrog ib tug sledgehammer kom cov phiaj nyob ze li sai tau rau ib leeg. Qhov twg qhov txiav mus dhau qhov khooblub qhov, cov hniav yuav tawg sai heev.
Kev txiav cov ntaub pua plag hla qhov dav yuav ntev dua thiab nyuaj dua, vim tias koj yuav tau txiav cov fittings uas tuaj hla. Txhawm rau ua qhov no, koj tuaj yeem siv lub tshuab sib tsoo, tab sis kom lub disk tsis "tom", koj yuav tsum txiav tus pas nrig tsis tag, tab sis tawm ob peb millimeters, thiab tom qab ntawd thaum kawg tawg nrog lub sledgehammer.
Txawm tias ua haujlwm zoo npaum li cas los xij, kev ncaj ncees ntawm cov nplais tseem raug ua txhaum. Koj tuaj yeem zam qhov no hauv cov hauv qab no:
- Ua raws li cov txheej txheem ntawm kev teeb tsa hauv pem teb slabs - pib nteg cov slabs ntawm ib sab thiab ua tiav kev ua haujlwm ntawm lwm qhov. Tsis muaj teeb meem koj yuav tsum pib nteg tawm ntawm ob sab - txawm tias txhua yam converges raws li kev suav, nws yuav tsis muaj peev xwm nteg nruj nreem rau ntawm cov phaj sib txuas kom tsis muaj qhov sib txawv ntawm nws thiab cov pob zeb uas nyob ib sab. Qhov no ua txhaum ob qhov nruj ntawm kev sib txuas thiab lub zog ntawm lub vev xaib.
- Yog tias daim ntaub tsis muaj me ntsis, koj tuaj yeem tso qhov khoob ze ntawm cov phab ntsa, uas tau muab tso rau hauv cov blocks, thiab tom qab ntawd ua cov cement screed. Yog hais tias qhov khoob qhov qhib tshaj qhov deb ntawm 30 cm, nws yuav tsum tau ua ib tug screed los ntawm reinforcement.
- Cia qhov kev ncua deb ntawm daim phiaj lawv tus kheej. Tom qab ntawd cov voids raug kaw los ntawm hauv qab nrog cov dej-resistant plywood, lub reinforcement yog nteg kom nws mus dhau lub Upper npoo ntawm slabs, thiab lub resulting formwork yog poured nrog pob zeb. Thaum cov mortar dries, cov plywood tuaj yeem raug tshem tawm thiab cov screed dav dav tuaj yeem ua rau saum cov laug cam.
Tom qab kev teeb tsa tiav
Txhawm rau kom lub tsev nyob yav tom ntej kom muaj zog thiab ruaj khov, lawv nqa ib pawg ntawm cov khoom siv ntxiv ntawm txhua tusntsia cov ntsiab lus. Ua li no, ib kawg ntawm txhua tus pas nrig yog welded rau lub voj ntawm ib lub canvas, thiab lwm yam mus rau lub voj ntawm lub canvas uas nyob ib sab.
Kev Ceeb Toom: nws tsis tuaj yeem txuas ob peb cov khoom siv pob zeb ntxiv nrog ib tus pas nrig - tsuas yog ob lub tsev nyob ib sab xwb.
