Thaum neeg feem coob hnov cov lus hais tias "lub tsev", lawv xav txog lub tsev ntoo. Txawm li cas los xij, muaj cov tsev tsim tsa uas siv cov txheej txheem-monolithic thev naus laus zis, uas yog ua los ntawm cov pob zeb. Cov hlau profile lossis cov pob zeb muaj zog tuaj yeem siv tau thaum ua haujlwm. Cov ncej yog sheathed nrog cov cement particle boards, thiab cov phab ntsa lawv tus kheej tuaj yeem ua los ntawm cov blocks lossis cib. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov vaj tse zoo li no muab rau qhov yuav tsum tau teeb tsa lub diaphragm khov kho, cov qauv tsim uas yuav tau tham hauv qab no.
Destination
Vertical phab ntsa panels tau nruab nruab nrab ntawm kab rau tag nrho qhov siab ntawm cov vaj tse ncej. Lub tom kawg yuav muaj txee rau sab sauv rau kev txhim kho pem teb slabs.
Cov ntsiab lus no txuas cov kab ke sib txuas rau ib leeg thiab rau ib leeg, thaum lawv muab spatial rigidity rau tag nrho lub tsev. Lawv yuav tsum nyob rau hauv cov tsev nyob rau hauv tag nrho cov lus qhia nyob rau hauv xws li ib tug txoj kev uasmuaj kev sib tshuam thiab T-puab lossis L-zoo li tus duab tau tsim. Lawv fastening nrog txhua kab yog nqa tawm nyob rau hauv qhov siab tsawg kawg yog peb lub ntsiab lus. Nyob rau hauv rooj plaub no, welding ntawm embedded qhov chaw yog siv. Stiffening diaphragms feem ntau yog ntsia rau ntawm lub hauv paus sawb, qee zaum monolithic slabs ua raws li hauv paus.
Tsim
Diaphragms uas siv los ua kom nruj tuaj yeem muaj ntau hom kev tsim kho, ntawm lawv yog:
- ob-txheej;
- single-shelf;
- solid;
- nrog qhov rooj;
- compound;
- nrog qhov cua ducts.
Nyob rau hauv rooj plaub tom kawg, peb tab tom tham txog diaphragms, uas yog qhov cua thaiv. Cov vaj huam sib luag rau cov diaphragms no yog ua los ntawm M-300 chav ua vaj tse, qhov no siv rau cov plag tsev hauv qab ntawm lub tsev, thaum M-200 qib mortar yog siv rau qhov kawg.
Cov tawv nqaij diaphragms tuaj yeem tsim nyob rau lub sijhawm sib txawv ntawm lub xyoo. Yog tias kev ua haujlwm tau ua nyob rau lub caij ntuj sov, lub zog ntawm cov pob zeb yuav tsum yog 70% ntawm qhov tsim, thaum lub caij ntuj no daim duab no yuav tsum ncav cuag 100%. Kev txhawb zog ntawm cov pob zeb ua vaj huam sib luag prefabricated yog tsim los ntawm qis thiab sab sauv racks, nrog rau cov thaiv thaiv, uas muaj qhov loj me. Yog tias qhov siab ntawm tus ncej tsis tshaj 3 m, thiab lub diaphragm tsim tsis muaj lub qhov rooj lossis lwm qhov qhib, ces lub thav duab tuaj yeem hnav.
Dab tsi ntxiv koj yuav tsum paub txog tus qauv tsim
Cov tawv nqaij diaphragms yuav muaj nyob hauv lawvmuaj qhov qhib rau kev txhawb nqa raws li ib puag ncig. Nyob rau hauv cov ntaub ntawv no, lub concentration ntawm kev ntxhov siab nyob rau hauv cov ces kaum yuav tsum tau coj mus rau hauv tus account. Lub luag haujlwm tseem ceeb hauv qhov no yog kev sau cov pylons stiffening. Nws yog ib qho tseem ceeb uas yuav tsum tau ua cov kev suav ntawm geometric parameters thiab xyuas seb lub zog puas haum rau cov yam ntxwv. Kev ua yeeb yam hauv cov qauv yuav tsum tau txheeb xyuas. Txawm li cas los xij tus qauv tsim ntawm stiffening diaphragms, lawv yog tsim los rau hauv nruab nrab compression, nrog rau shear rog los ntawm kab rov tav thiab ntsug loads. Yog tias muaj qhov qhib, cov ntsiab lus yuav tsum tau kuaj xyuas qhov sib koom ua ke ntawm kev ntxhov siab rau saum phab ntsa.
Txhim kho qhov tawv nqaij diaphragms
Monolithic stiffening diaphragms yuav tsum nyob rau hauv qhov dav ntawm cov kab, lawv cov kev sib txuas mus rau ib leeg yog nqa los ntawm kev siv lub hlaws monolithic, nws yog mounted rau sab sauv ntawm lub diaphragm. Qhov tom kawg yuav tsum txuas mus rau tag nrho qhov siab ntawm lub tsev, thiab qee zaum nws muaj peev xwm hais tias cov ntsiab lus tsis raug ntsia rau hauv pem teb technical.
Hauv pem teb hauv qab yuav tsum tau so ntawm lub hauv paus grillage nrog kev pab los ntawm cov khoom embedded. Txhawm rau kom muaj kev ruaj ntseg ntawm lub tsev, diaphragms raug teeb tsa hauv ob qho tib si. Cov kab ntsug yuav tsum tau muab tso rau sib npaug raws li txoj kev npaj, lawv tau ua ke nrog cov laj kab ntawm lub elevator units. Cov tawv nqaij diaphragm nyob rau hauv thav duab vaj tse yuav tsum tau ntsia nyob rau hauv tus nqi ntawm tsawg kawg peb nyob rau hauv ib tug kub thaiv. Lub geometric axes ntawm cov ntsiab lus yuav tsum tsis txhob sib tshuam, qhov nruab nrab ntawm lub ntiajteb txawj nqus yuav tsumcoincide nrog qhov chaw ntawm lub ntiajteb txawj nqus ntawm lub axis ntawm lub tsev.
Txhawm rau kom cov spatial rigidity ntawm lub tsev uas muaj ntau dua ntawm cov khw muag khoom, nws yog ib qho tsim nyog los muab kev ntsuas kom paub tseeb ntawm cov diaphragms nrog tus ncej. Qhov no tuaj yeem ua tiav nrog kev sib txuas ntawm qhov tseem ceeb ntawm kem thiab lub orifice.
cov lus qhia txog kev txhim kho
Yuav kom cov phab ntsa kom muaj zog li sai tau, lub diaphragm khov yuav tsum muaj nyob hauv lub tsev. Yog tias peb tab tom tham txog II-04 series, tom qab ntawd hauv cov ces kaum sab saud ntawm cov khoom zoo li no yuav tsum muaj cov undercuts, ntawm cov consoles ntawm txhua kab yuav tom qab tso. Tsis tas li ntawd, muaj qhov hluav taws xob ntawm steel rods nyob rau hauv lub ces kaum ntawm lub diaphragm. Txhawm rau txhim kho lub diaphragm ntawm cov koob no, lub voj kaw yog siv rau ntawm lub thav duab ua los ntawm steel rods, txoj kab uas hla ntawm lub tom kawg tuaj yeem sib txawv ntawm 12 mus rau 28 hli. Cov pas nrig yog ib txwm welded rau ntxiv zog.
Cov tawv tawv diaphragm series yuav zoo li 1.020-1, nyob rau hauv cov ntaub ntawv no tsis muaj kaum txiav ntawm lub ntsiab. Cov qauv zoo li no tau ntxiv dag zog nrog tshwj xeeb ntsug thav duab, thiab cov hlau mesh yog kho raws li ib puag ncig ntawm cov qauv, txoj kab uas hla ntawm nws cov pas nrig tuaj yeem sib txawv ntawm 5 mus rau 12 hli, thaum lub hlwb muaj qhov loj ntawm 200 hli. Diaphragms ntawm cov koob no tau teeb tsa tib lub sijhawm rau cov kab hla, thiab tom qab ntawd hloov cov khoom tsim no.
Zoo kawg
Cov diaphragms uas sib npaug rau cov kab hla tsis muaj qhov ntxivconsoles. Ntawm cov npoo ntsug ntawm II-04 muaj qhov chaw nrog kev pab cuam uas cov txheej txheem thav duab yuav txuas nrog cov kab. Yog tias koj yuav siv 1.020-series diaphragm, ces koj yuav tsum npaj cov khoom siv rau nws.
Nws tseem tsim nyog hais tias diaphragms hu ua stiffening cores, thiab yog ib qho tseem ceeb ntawm lub tsev rau txhua lub hom phiaj. Lub luag haujlwm ntawm cov khoom no yog qhov kev nkag siab ntawm kab rov tav loads los ntawm hom seismic thiab cua uas cuam tshuam rau lub tsev.
