Zojambulajambula zamatabwa (kapena zokopa) - zokongola kwambiri, zomwe zimakhala ndi mtengo wamtengo wapatali, wokonda komanso wokongoletsera, njira yophimba.
Njerwa yamatabwa ya njanji yamtunda, yopangidwa ndi zachilengedwe, yotetezeka - dongo, imagwiritsidwa ntchito popangira njira za m'midzi ndi kumidzi. Tile yotereyi imasiyanitsidwa ndi mphamvu yowonjezereka, njira zomwe zimagwiritsidwa ntchito, kuyang'ana zokongola, bwalo panthawi imodzimodziyo ali ndi mawonekedwe apamwamba ndi okongoletsedwa bwino.
Zojambula za njerwa zimayang'anitsitsa ndi zojambula zilizonse, zosavuta kuzikamo. Ndizotheka kugwiritsa ntchito bwino porous pamwamba pa mtundu uwu wa pulasitala kuti ukhale ndi maluwa ndi zomera zofanana ndi pores, motero kupanga choyambirira, mawonekedwe okongoletsera a m'munda wamunda.
Njerwa zazitali zimakhalabe ndi maonekedwe kwa nthawi yaitali, osasunthika kuchokera ku kusintha kwa kutentha ndi chinyezi.
Momwe mungaike njerwa pamoto?
Pali mitundu yambiri yotchuka yojambula matabwa a njerwa. Chilengedwe chonse ndi chophweka kwambiri ndi malo ake osasangalatsa. Makhalidwe komanso njira yosavuta kumayika matayala ndi zovuta.
Njira yokongola ya kuyala imawoneka ngati chitsanzo cha herringbone kapena braid. Zida zimayikidwa muyeso yoyamba - wedges, ndipo yachiwiri - kumbali yoyenera, kupanga zotsatira za kuyika.
Chimodzi mwa mitundu yosavuta kwambiri, yokonzedwa pogwiritsa ntchito mitundu iwiri, imayikidwa ndondomeko ya chess. Pofuna kupanga chojambulajambula kapena mtundu wozungulira, makamaka amagwiritsa ntchito zosiyana-siyana, mawonekedwe ndi mtundu.

Pali njira zitatu zazikulu zothetsera njerwa. Njira yosavuta komanso yotchipa ndiyoyikidwapo mchenga, imatsanulira mu nkhungu wosanjikizika, kukulitsa kwambiri kuposa theka.
Kwa njira yachiwiri, imagwiritsa ntchito mchenga wa simenti, womwe umakhazikika, umamangirira zinthu zonse pamodzi.
Njira yachitatu ndi yodalirika, yowonjezereka mu matekinoloje ndi kuyika matayala. Kuika matayala kumachitika ndi glue wapadera kapena matope wamba, zovuta zimaphatikizapo mfundo yakuti, zidutswa zowonongeka zidzakhala zovuta kuti zisinthe.
