** ceeb toom tseem ceeb:** Qhov no yog cov ntawv sau keeb kwm, tsis yog tus qauv tam sim no, ru tsev lossis facade tsim, lossis phau ntawv ua haujlwm. Dimensions, chav kawm, lub cev-mechanical qhov tseem ceeb, tshuaj tiv thaiv, txoj kev sib txuas thiab kev piav qhia ntawm cov txheej yuav tsum tau kuaj xyuas raws li cov cai siv tau, cov chaw tsim khoom cov ntaub ntawv thiab cov phiaj xwm tshwj xeeb.
Cov ntawv no tsis yog ib feem ntawm qhov kev thov tam sim no ntawm Savo Kusić, uas yog tsom rau lub qhov rais, qhov rooj thiab cov kev daws teeb meem.
Qhov ntev thiab hom ntoo
Hauv kev lag luam ntoo loj, cov vuas ntoo thiab cov vuas cladding, cov duab plaub, feem ntau yog tsim los ntawm cov khoom pov tseg los ntawm ib txwm tsim (fig. 14).
Daim duab. 14 Ntoo vuas rau vov tsev thiab cladding
Lawv yuav tsum muaj qhov loj me hauv qab no: ntev (l) yam tsawg 400, thiab feem ntau 600 mm, nrog nce ntawm 50 mm; dav (b) yam tsawg kawg 70 mm; thickness ntawm ib sab (h1) - 13 mm, ntawm lwm yam (h2) - 3 mm. Tso cai sib txawv ntawm qhov ntev yuav tsum tsis pub tshaj ± 5 mm nyob rau hauv ntev, thiab ± 1 mm nyob rau hauv thickness.
Cov vuas no yog tsim los ntawm ntoo thuv, spruce, fir, cedar thiab larch.
Cov chav kawm zoo
Raws li qhov zoo ntawm cov ntoo thiab nws cov txheej txheem, muaj peb chav kawm ntawm cov vuas ntoo: I, II* thiab III. Lawv cov av noo yuav tsum tsis txhob siab tshaj 25%. Nyob rau hauv chav kawm I cov vuas, cov pob ntoo uas muaj fused nrog cov ntoo, nrog rau cov tawv nqaij, tsis raug tso cai. Tsis muaj zog, fiber ntau tsis xwm yeem, sib tw, cov hnab yas, cov kab nrib pleb mus txog 50 mm ntawm lub ntsej muag nyias tau tso cai.
Sl.15. Lub ru tsev npog ua los ntawm cov vuas ntoo: a - ob txheej, b - peb txheej
Hauv ** II ** thiab ** III ** chav kawm, noj qab nyob zoo fused nodes raug tso cai ntawm feem ntau ntawm ib3pieces ntawm loj mus txog20 mm, nyias tawg mus txog rau50 mm, bruising nyob rau hauv daim ntawv ntawm ib tug neeg me ntsis, nruj, irregularity ntawm fiber txaus, twisting thiab resin hnab.
Sl.16Npog cov phab ntsa nrog cov vuas ntoo; a - ntsug ntu, b - facade, c - puag,1- Scope,2- filling,3- impregnated cardboard,4- cov nplais
Raws li qhov ua tau zoo ntawm cov ntoo ua, tsis muaj qhov ntse lossis blunt ua tiav, nrog rau cov ntawv sau, qhov chaw tawg thiab cov dents ntawm lub ntsej muag raug tso cai hauv txhua chav kawm. Txoj kab nqes ntawm cov kab rau I chav kawm yuav tsum tsis txhob tsawg dua60o, thiab rau II thiab III - los ntawm30o. Kev suav cov vuas yog ua hauv m2.

Yuav kom muaj lub neej ua haujlwm ntev dua, cov vuas vov tsev yuav tsum tau impregnated nrog cov tshuaj tua kab mob thiab cov nplaim hluav taws (cov tshuaj tiv thaiv hluav taws xob). Vuas yuav tsum tau nailed nrog galvanized ntsia hlau. Lub ru tsev yog them nrog cov vuas ntoo hauv ob thiab peb txheej (fig. 15). Hauv ob txheej - rau cov tsev nyob, hauv peb txheej - rau cov tsev tsis nyob. Cov vuas yog muab tso rau saum lub hauv paus ntoo ua los ntawm slats. Pw pib los ntawm wreath. Txhua lub pobzeb yog nailed nyob rau hauv lub longitudinal axis mus rau lub hauv paus nrog ob tug ntsia hlau nrog lub taub hau dav. Lub thickness txheej yog 1,4 - 1,6 mm, lawv ntev yog 40; 45 lossis 50 mm.
Npog cov phab ntsa nrog cov vuas ntoo yog ua los ntawm nailing cov vuas ncaj qha rau ntawm phab ntsa lossis rau lub hauv paus ua los ntawm slats, uas yog txuas nrog cov pob txha ntoo ntawm phab ntsa (fig. 16). Ntawm 1 m2 ru tsev nto, 35 pobzeb loj 600 x 120 mm yog siv. Thaum pw hauv ob txheej, thiab 52 vuas thaum pw hauv peb txheej.
Rau lub ru tsev niaj hnub los yog lub façade, tsim kev txheeb xyuas, cov qauv tam sim no, cov khoom lag luam raug tshaj tawm, kev tiv thaiv ntoo ruaj ntseg thiab cov ntsiab lus uas cuam tshuam rau kev nyab xeeb thiab kev tsim kho. Cov txiaj ntsig keeb kwm thiab cov txheej txheem los ntawm cov ntawv no tsis yog kev ua haujlwm tshwj xeeb.
