Ndi kulemera kwa 1 M3 konkire Kodi

Panopa, zaka monga zambiri zapitazo, konkire mwina chuma ambiri kumanga nyumbayo. Izo ntchito pamene akuchita zosiyanasiyana ntchito yomanga - by overhauls kwa yomanga nyumba. Komabe, kugwira ntchito iliyonse chinthu choyamba inu mukufuna kudziwa kuchuluka kwa chuma chofunika, kutenga nkhani makhalidwe ake. Mwachitsanzo, omanga nyumba zambiri zovuta kudziwa kulemera kwa mita kiyubiki za izo. Choncho, nkhani ino ikunena pa funso la kodi kulemera kwa 1 M3 konkire.

Kuyambira chimene chimadalira pa misa konkire

Choyamba, tisaiwale kuti omanga sindigwiritsa ntchito chinthu choterocho monga "kulemera enieni konkire." Ichi ndi chifukwa chakuti zomangila mu kapangidwe kake akhoza muli zosiyanasiyana zigawo kuti ndi miyeso osiyana.
Choncho, monga filler akhoza kugwiritsidwa ntchito:
• miyala.
• miyala.
• zowonjezera dongo ndipo ena.
Ngakhale, ntchito yokonza matope konkire ntchito zikuchokera chomwecho, kulemera kwa 1 M3 konkire akhoza zosiyanasiyana milandu kumene filler ali tuzigawo twa osiyana. Ikuluikulu nusu, ndi voids zikuluzikulu m'nkhaniyo ndi moyenera, kupatula misa.

Komabe, omanga akadali chidwi makhalidwe kulemera, chifukwa cha mtengo wa index izi zimatengera pa makhalidwe ambiri a zinthu za executable. Mwachitsanzo, ntchito pamaziko a deta awa, mawerengedwe a kulemera , ndipo anasankha kupanga zapansi pa nthaka zosiyanasiyana. N'chimodzimodzinso ndi ena zinthu katundu mwankhanza.

Zochita omanga ntchito chizindikiro amatchedwa "chochuluka kachulukidwe." Koma mbali alibe phindu zonse. Komanso anapezazo ayenera kuganizira kulemera kwa madzi ntchito yokonza njira.

mitundu konkire

Ndi mtundu wa binder, nkhaniyi nyumba anapambulwa pa simenti, laimu, shlakoshchelochnyh, phula ndi ena. Ndi cholinga anapambulwa concretes mwachizolowezi (chifukwa boma ndi nyumba mafakitale), wapadera (m'misewu, zokongoletsera, chimateteza, hayidiroliki) ndi cholinga chapadera (mankhwala kugonjetsedwa, phokoso-mtima, kutentha zosagwira kuti adziteteze ku cheza nyukiliya, etc.).

makhalidwe konkire

Monga chizindikiro zikuluzikulu amakhala konkire, mphamvu compressive ntchito. Mkhalidwe umenewu ndiyo kalasi konkire, anasonyeza mwa kalata "B" (Latin), ndi manambalawo kutanthauza (mu makilogalamu / cm²) katundu mphamvu. Mwachitsanzo, B25 mtengo zikusonyeza kuti gulu konkire lakonzedwa kuti katundu wa makilogalamu 25 / cm. Pamene kuwerengetsa zizindikiro za mphamvu ya nyumba ayenera zinthu nkhani. Chitsanzo: yomanga ndi simenti kalasi B25 pa mtengo koyefishienti a kusintha peresenti 13.5 kupirira katundu 327 makilogalamu / cm, lomwe ndi lofanana M350 mphamvu mtundu. Mphamvu kalasi V3,5 limafanana mtundu mphamvu M50, B10 - M150, B30 - M400 ndi B60 - M800.

zizindikiro zina zofunika monga simenti chisanu kukana, mphamvu flexural ndi madzi kukana. kukana Frost ndiwo amaimira «F» ndipo chiwerengero cha 50 500, kutanthauza chiwerengero cha kusintha kwa limati amaundana thawing ndi kumbuyo umene kupirira konkire. Pakuti madzi kukana index ntchito kalata «W» ndi nambala 2 ndi 12, amene amasonyeza kuthamanga madzi, amene amathandiza chitsanzo cha kalasi konkire mu mawonekedwe a yamphamvu ndi.

kulemera Khama

deta lina kulemera volumetric wa simenti akufotokozera SNP № II-3. Muyezo n'chakuti pafupifupi kulemera kwa mitundu konkire malingana ndi mtundu wa filler izo. Iwo ali kulemera kwa tebulo simenti imene mukhoza kuona kuti mankhwala konkire yodziwika ndi chochuluka kachulukidwe (makilogalamu / M3) 2500 simenti ndi filler mu mawonekedwe a miyala kapena mwala wosweka - 2400, pa maziko a kukodzedwa dongo wa kukodzedwa dongo mchenga - 500-1800, pa maziko a perlite - 800-1000. Nawonso konkire lokhala ndi mpweya wokwanira amakhala ndi osalimba ndi mtokoma wa 300-1000 makilogalamu / M3. Kumene, kulemera kwa 1 M3 konkire ali ndi khalidwe pafupifupi, koma deta izi bwino wosakanikirana ndi zolinga za Pamudzi. Pambuyo deta onse ali olondola makilogalamu angapo sangathe kupereka umboni uliwonse.

Konkire Kunenepa malingana mtunduwu

Kumathandiza nthawi zambiri zokonzedwa ndi kulemera kwa 1 M3 konkire, malingana sitandade. Lolemera mitundu yake yodziwika ndi ziwerengero zotsatirazi. Kulemera simenti M200 ndi 2430 makilogalamu / M3. Awonetse M100 akhoza kugwiritsa ntchito mtengo wa 2495 makilogalamu / M3. Kulemera simenti M300 - 2390, ndi zizindikiro M400 ndipo M500 akhoza kutenga mfundo 2375 ndi 2300 makilogalamu / M3, motero.

Motero, m'nkhani mfundo kachulukidwe angagwiritsidwe ntchito kuyandikira kuwerengetsera zomangamanga kupanga kukonza ndi kumanga ntchito.
