Kodi matabwa odulidwa?

A yomanga kawirikawiri akhoza kuchita popanda kugwiritsa ntchito kokha bar. matabwa ameneyu ndithu chimagwiritsidwa ntchito shipbuilding, kumanga nkhuni ndi yokongola. Nkhanizi ndi chimodzi-chidutswa matabwa, nakonza kumbali zonse, kukhala ndi amakona anayi kapena lalikulu mtanda chigawo ndi amapangidwa softwood (monga paini, spruce, Oil, larch).

Gawo

Malinga ndi khalidwe la odulidwa matabwa lagawidwa kalasi yoyamba ndi yachiwiri:

• Choyamba - alandire matabwa popanda Madontho ndi mfundo.
• Maphunziro II - mankhwala ndi zina zopindika.

Komanso konsekonse matabwa akhoza kukhala wouma kapena zachilengedwe chinyezi. zakuthupi youma imatengedwa zogwirizana kwambiri, kuyambira zayamba kumachepetsa shrinkage wa nyumba itatha. Komanso, mfundo yotero ndi opepuka, zosavuta ntchito ndi zoyendera lomwe zochepa atengeke mapangidwe nkhungu inali kuwola.

odulidwa matabwa angathe kukonzedwa m'njira zosiyanasiyana:

• Calibrated - kwathunthu zouma ndi kukonzedwa.
• Dvuhkantny - ankachitira ndi mbali longitudinally zosiyana awiri.
• Trehkantny - atatu longitudinally mankhwala pamwamba.
• Chetyrehkantny - kukonzedwa pa onse mbali zinayi kotenga.

Wotchuka kwambiri imatengedwa trehkantny mwina chifukwa limakupatsani kulenga wokongola kuchokera ku mbali zokongoletsa ya zomangamanga padziko yabwino kukongoletsa kuwamaliza. Nyumba zomangidwa ku matabwa zimenezi, kunja zikuwoneka ngati tselnobrevenchatye ndipo Mkati mwake yosalala, oyenera aliwonse mapeto.

Konsekonse matabwa: Masayizi

Kukula konsekonse matabwa akhoza kukhala motere:

• makulidwe - kuchokera 25 mpaka 200 mm;
• kutalika - 3.6 mamita;
• m'lifupi mu osiyanasiyana mamilimita 50 250.

Malinga GOST, m'lifupi ndi makulidwe a ndodo kokha ayenera kukhala osachepera 100 mm. Zonse wowonda, likutchedwa kapamwamba.

ntchito

Matabwa - ambiri mtundu wa matabwa, amene ali osiyanasiyana kwambiri ofunsira. Izo ntchito monga chuma kandalama ziwembu zosiyanasiyana matabwa. Ndi kuti kukhala anamanga joists, makoma, machitidwe osiyanasiyana denga, etc. Komanso, matabwa ameneyu ndithu ankagwiritsa ntchito mu makampani mipando ndi kupanga joinery.

M'zaka zaposachedwapa, za kutchuka ndi matabwa makamaka odulidwa analandira yomanga matabwa. Chifukwa waubwenzi kuwononga chilengedwe ndi kusinthasintha iye zikufunika mkulu kumanga katundu mwankhanza makoma a nyumbazo, attics ndi ena.
