Ntoo nyob ib qho chaw tshwj xeeb ntawm cov khoom siv hauv tsev. Yav dhau los, tsis yog tib lub tsev xwb, tab sis tag nrho cov nroog tau tsim los ntawm nws. Cov qauv ntoo yog siv dav hauv kev lag luam niaj hnub tsim. SNiP ||-25-80 yog cov ntaub ntawv tseem ceeb, daim ntawv qhia tsim, nrog rau cov txheej txheem los tiv thaiv cov khoom siv thiab cov khoom tsim los ntawm nws.
Ntoo yog tus yam ntxwv los ntawm kev tsim khoom siab, tsis tshua muaj lub ntiajteb txawj nqus thiab yooj yim ntawm kev ua haujlwm. Hauv kev tsim cov qauv tsim xws li lub qhov rais thav duab, cov qhov rooj sab hauv nrog trusses, truss systems, coniferous ntoo yog tsuas yog siv. Cov hom no yog cov feem ntau thiab ncaj ncees resistant rau sab nraud influences. Cov ntoo ntoo muaj txiaj ntsig tuaj yeem siv rau cov qauv tseem ceeb thiab thauj khoom.
Txoj kev tsim cov khoom siv ntoo
Cov qauv yuav tsum muaj lub zog tsim nyog thiab ruaj khov. Ua kom ntseeg tau tias cov yam ntxwv xav tau yog lub hom phiaj ntawm kev tsim thiab suav cov dej num. Cov qauv ntoo tsim nyog tau txais kev saib xyuas tshwj xeeb thaum lawv siv. SNiP txhais cov kev cai yooj yim rau kev suav suav. Cov kabmob muaj peev xwm ntawm cov khoom thiab qhov kawg deformation yuav tsum ua tau raws li cov qauv tsim.
Ua kom lub sijhawm ua haujlwm ntev ntawm cov tsev, suav nrog kev cuam tshuam ntawm cov khoom sab nraud, cov khoom thauj tsis tu ncua thiab sib txawv - cov no yog cov cai tseem ceeb ntawm SNiP. Ntoo ru tsev qauv thiab interfloor ceilings nyob rau hauv qis-sawv vaj tse yog feem ntau dav siv. Qhov laj thawj tseem ceeb yog tus nqi qis thiab yooj yim ntawm kev tsim khoom. Hauv kev xyaum dav, feem ntau cov qauv txheej txheem thiab cov lus pom zoo ntawm cov kws tshaj lij tau siv.
Txhim kho kev tiv thaiv kev tiv thaiv ntoo
Kev lees paub siab tshaj plaws ntawm txhua qhov zoo ntawm cov khoom siv hauv tsev no tsuas yog ua tau yog tias nws tiv thaiv qhov chaw sab nraud tau lees paub. High flammability, susceptibility rau kev puas tsuaj los ntawm ya raws thiab lom kab tsuag - ntoo qauv muaj cov tsis zoo. SNiP muab cov txheej txheem ntsuas los tiv thaiv lawv thiab txo qis qhov tshwm sim tsis zoo.
Txoj kev tiv thaiv ntoo los ntawm hluav taws kub, cov av noo siab lossis kab tsuag tau tsim thiab txhim kho. Yog li, kev kho cov rafters, cav thiab kab teeb nrog cov tshuaj tshwj xeeb - cov nplaim hluav taws tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws. Cov tshuaj tua kab mob tuaj yeem tiv thaiv kab tsuag thiab tiv thaiv kev loj hlob ntawm pwm thiab fungi.
Cov khoom siv ntoo ntxiv
ruaj khov thiab muaj zogntoo lub tsev yog ua tiav los ntawm kev siv cov ntaub ntawv uas tsim nyog. Phau ntawv rau SNiP ntoo qauv ntxiv rau GOST 8486-66 thiab 9463-72 imposes ib co ntxiv yuav tsum tau. Qhov no cuam tshuam txog qhov dav ntawm lub nplhaib txhua xyoo, kev siv lub hauv paus ntawm lub cev - cov tub ntxhais thiab cov dej noo ntawm cov array.
Cov ntaub ntawv tshiab thiab cov khoom tsim los ntawm lawv pom daim ntawv thov hauv kev tsim kho. Nyob rau hauv xyoo tas los no, profiled ntoo qauv tau siv ntau zuj zus. SNiP txhais cov kev cai yooj yim rau lawv thiab cov cai rau lawv siv.
