Pomanga nyumba, konkriti nthawi zambiri imagwiritsa ntchito madzi omwe alipo.Ngakhale kuti njirayi ndi yokhwima, imakhalanso ndi mphamvu zambiri zogwiritsira ntchito mphamvu, kuipitsa kwambiri komanso teknoloji yochepa.Mu "low carbon economy", "green building" akutuluka mfundo monga chitsogozo, kusintha njira yomanga nyumba, kulimbikitsa nyumba mafakitale, chitukuko cha Prefabricated nyumba wakhala mchitidwe wosalephereka wa dziko lathu chitukuko cha nyumba malinga ndi zinachitikira zikusonyeza kuti Poyerekeza ndi njira yomangira konkriti yachikhalidwe, Nyumba zopangira zopangira zosungira madzi 80%, pulumutsani zinthu ndi 20%, kuchepetsa zinyalala zomanga ndi 80%, kupulumutsa mphamvu zonse 70%, kuchepetsa ndalama zokonza ndi 95% .Panthawi imodzimodziyo, malo omangawo akhoza kuchepetsedwa kuti agwiritse ntchito bwino malo.
Zofunikira pakugwirira ntchito kwa zomatira zosindikizira za nyumba Yokonzedweratu
Adhesion ndi imodzi mwazinthu zofunika kwambiri pa sealant.N'chimodzimodzinso ndi zipangizo zoyambira zomwe zimagwiritsidwa ntchito m'nyumba Zokonzedweratu.Pakalipano, mbale zambiri za PC zomwe zimagwiritsidwa ntchito pamsika zimapangidwa ndi konkire, kotero pali kumamatira kwabwino ku gawo lapansi la konkire kwa seams.Pakuti zinthu konkire, wamba sealant adhesion pamwamba si kophweka kukwaniritsa, izi ndi chifukwa: (1) konkire ndi mtundu wa porous zakuthupi, kugawa mkodzo wa kukula kwa dzenje osati kothandiza sealant adhesion;zamchere (2) konkire palokha, makamaka m'munsi zinthu bibulous, mbali ya zinthu zamchere amasamukira ku sealant ndi konkire kukhudzana mawonekedwe, motero zimakhudza adhesion;(3) PC bolodi chidutswa pa mapeto a msonkhano prefabrication kupanga, kuti amasulidwe adzagwiritsa ntchito nkhungu kumasulidwa, ndi mbali ya wothandizila kumasulidwa otsala padziko PC bolodi chidutswa, komanso kupanga chisindikizo zomatira ndodo kulandira vuto.
