Cov khoom siv vov tsev hu ua tar paper yog ib zaug nrov heev, tab sis tam sim no nws siv tsis tshua muaj. Tab sis cov ntsia hlau puag ncig (GOST 4029-63), siv rau nws txoj hlua khi, tau txais daim ntawv thov tshiab.
Tshwj xeeb kho cov khoom
Cov lus nug feem ntau tshwm sim, hom rau tes twg zoo dua siv thaum ua haujlwm nrog cov khoom ntoo? Raws li txoj cai, hauv cov xwm txheej zoo li no, cov ntsia hlau ua los ntawm cov hlau, tooj liab, tooj dag thiab tooj liab yog siv. Txhawm rau kom muaj kev sib raug zoo ntawm cov qauv ntoo, nws yog ib qho tseem ceeb kom paub tias hom boards yuav siv li cas, nrog rau qhov ntev ntawm cov fasteners.
Hom ntsia hlau tsim los ntawm cov khoom siv hlau yuav txawv ntawm qhov sib txawv ntawm cov tub ntxhais, lub taub hau, conical lossis tiaj tus. Piv txwv li, yog tias tus ntsia thawv loj yog 1.6 hli, nws tuaj nrog lub taub hau tiaj tus, thiab ib txoj kab uas hla loj qhia txog lub taub hau conical. Txoj kab uas hla ntawm lub taub hau yog ob npaug ntawm txoj kab uas hla ntawm tus pas nrig.
Txhob siv cov ntsia hlau no
Cov ntsia hlau yog tsim los rau cov ru tsev. Ib qho tshwj xeeb ntawm cov ntsia hlau no yog suav tias yog ib qho kev zamkev ua txhaum ntawm kev sib xyaw ua ke ntawm cov khoom siv hauv kev tsim kho lub ru tsev, uas muaj zog tsawg. Lub hom phiaj ntawm kev siv cov ntsia hlau zoo li no yog txhawm rau txhawm rau cov ntaub ntawv uas tshwj xeeb yog mos. Lawv zoo tagnrho rau kev ua hauj lwm nrog vov tsev thiab ru tsev muaj kev xav (li no lawv lub npe ncaj qha). Lub xub ntiag ntawm cov kaus mom dav, lub taub hau tiaj tus tso cai rau kev txhim khu kev ruaj ntseg ntawm lub ru tsev, tsis suav nrog kev puas tsuaj rau cov ntaub ntawv uas muaj me ntsis tuab. Qhov no txuag lub sijhawm thiab nyiaj txiag vim cov khoom no yuav tsis ua puas tsuaj rau cov khoom siv hauv tsev.
txheej txheem tsim khoom thiab siv cov ntsia hlau vov tsev
Cov ntsia hlau zoo li no tso cai rau koj kom nrawm nrawm:
- khoom siv vov tsev, tsuas yog;
- yoog raws bituminous ceramics;
- asbestos cement vuas;
- daim ntawv dav siv hauv tsev ru tsev battens.
Cov ntsia hlau no tau ua tiav hauv kev sib dhos ntawm cov khoom siv rooj tog. Lawv tso cai rau koj kom ruaj ntseg txuas cov ntaub ntawv xovxwm (fibreboard, MDF) rau cov ntoo. Nws kuj tseem siv tau rau hauv cov txheej txheem kho kom zoo nkauj.
Kev tsim cov rau tes nrog cov ntxhua khaub ncaws me me thiab cov khoom siv galvanized zam tsis txhob xeb uas tuaj yeem tshwm sim ntawm qhov chaw ntawm lub sijhawm.
Club hom muaj cov grooves tshwj xeeb nyob rau saum npoo ntawm tus pas nrig, uas lav kev ntseeg siab ntawm fastening.
Cov ntsia hlau, tsis zoo li cov tib neeg, yog qhov ruaj khov tshaj plaws rau khoov, nroghammering tsis phua cov khoom ntoo.
Kev hloov kho ntawm lub ru tsev ntawm cov ntsia hlau (raws li GOST) tau siv dav hauv kev vov tsev, muab kev ua haujlwm zoo, ruaj khov thaum ua haujlwm.
Daim ntawv thov nta
Thaum xaiv tus ntsia thawv, yuav tsum tau saib xyuas tshwj xeeb rau txoj kab uas hla ntawm nws cov tub ntxhais. Cov ntsia hlau nyias nyias thiab ntev yog feem ntau yuav khoov, ua rau cov khoom siv vov tsev puas tsuaj, uas yuav tsum tau kho lossis hloov.
Rau kev teeb tsa lub ru tsev zoo, cov ntsia hlau raug xaiv uas sib haum rau cov kev txwv hauv qab no:
- fastening ntawm cov khoom ntawm qhov chaw siab tshaj yog ua los ntawm cov khoom uas muaj qhov ntev ntawm 20-25 hli thiab lub taub hau ntawm 7 hli;
- ru tsev ntawm lub ridge thiab tav yog fastened nrog rau cov ntsia hlau ntev 30 mm, qhov tsawg kawg nkaus cap txoj kab uas hla yuav tsum yog 10 mm.
txheej txheem kev teeb tsa yooj yim: tus ntsia hlau yog tsav hauv nruj nreem nrog rauj kom txog thaum lub hau kaw ntom ntom nrog lub ru tsev.
Cov ntsia hlau vov tsev yog cov khoom tsim tshwj xeeb rau kev txhim kho cov vov tsev mos. Lawv tsis tshua siv rau lwm yam haujlwm.
