Momwe Mungamenyere misomali mu Njerwa Motetezedwa (Njira 2)
Zamkatimu
Kodi mwatopa ndi khoma lanu losavuta la njerwa?
Makoma a njerwa ndiwowonjezera panyumba iliyonse, koma bwanji ngati mutachita zambiri? Nanga bwanji kukhomerera msomali kuti upachike zokongoletsa? Mutha kupitanso patsogolo pophatikiza zokulirapo ngati matabwa okongoletsera ndi mashelufu othandiza.
Palibe kukayikira kuti misomali imatha kumenyedwa mu njerwa, koma chachikulu ndi chakuti njerwayo idzaphwanyidwa. Pali njira ziwiri zokhomerera misomali mu njerwa popanda kusokoneza kukongola kwake.
Pitirizani kuwerenga kuti mudziwe zambiri za njira ziwirizi.
Misomali yomanga mapulojekiti ang'onoang'ono
Misomali yomanga imapangidwa kuti igwiritsidwe ntchito mu konkriti kapena makoma a njerwa.
Msomali wamatabwa umapangidwa ndi chitsulo cholimba, chosagonjetsedwa ndi kupindika ndi kusweka. Nthawi zambiri amadziwika ndi grooves, ulusi kapena spiral grooves omwe amathandiza kukhomerera msomali. Ntchito yake yayikulu ndikumangika pakati pa zolumikizira zamatope kuti zizikakamira kapena kuthandizira zinthu.
Msomali womanga umagwiritsidwa ntchito bwino pamapulojekiti ang'onoang'ono, monga kupachika chithunzithunzi.
Gawo 1 - Kusankha Misomali Yoyenera Yomanga
Lamulo lalikulu la chala chachikulu ndikusankha misomali yomwe imatha kulowa mkati mwa mainchesi 1.25-1.5 (3.2-3.8 cm) kukhoma.
Yesani mosamala makulidwe a khoma la njerwa. Msomali uyenera kulowa mwakuya mpaka kukhoma osadutsa mbali inayo.
Ngati kuli kotheka, onetsani makulidwe a matabwa kapena zinthu zina zokhomeredwa poganizira za mtundu wa misomali yomanga.
Gawo 2 - Mark Hole Malo
Gwiritsani ntchito pensulo kuti mulembe malo oyenera kukhomeredwa.
Misomali yomanga misomali imayenera kukhomeredwa m'malo olumikizirana matope (malo apakati pa njerwa kapena midadada ya konkire). Izi zili choncho chifukwa kukhomerera njerwa mwachindunji kumatha kusweka kapena kusweka.
Ngati mukukonzekera kukhomerera thabwa pakhoma la njerwa, pangani chizindikiro pa bolodi lokha.
Kwezani matabwa pakhoma. Chongani malo a mabowo oti abowole. Pakhale mtunda wa mainchesi 18 mpaka 24 (45.72-60.96 cm) pakati pa dzenje lililonse. Onetsetsani kuti malo a dzenje lililonse ali pamwamba pa mfundo zamatope.
Khwerero 3 - Boworani Mabowo mu Masonry
Konzani kachidutswa kakang'ono kamene kamakhala ndi m'mimba mwake kakang'ono kuposa msomali.
Gwirani kubowola pamadigiri 90 kukhoma, kenaka ikani chobowolocho mosamala pamalo odziwika. Pitirizani kubowola mpaka kuya komwe mukufuna kufikika. Kokani chobowola pamwamba pa mwala uku ukuzungulirabe.
Pokonza bolodi, borani bolodi mu khoma la njerwa. Gwirani bolodi mosasunthika kuti mabowowo agwirizane.
Khwerero 4 - Menyani misomali
Ikani msomali mu dzenje lobowoledwa ndikuchimenya mosamala m'malo mwake.
Onetsetsani kuti msomali umagwirizana ndi dzenje ndikuwongoka. Gwiritsani ntchito nyundo pokhomerera msomali mumtondo. Iyenera kulowa mumatope osachepera 1.25 mainchesi (3.2 cm).
Sungani msomali mpaka mutu utagwedezeka ndi khoma kuti muteteze matabwa ndi zinthu zina pakhoma.
Nangula wa manja a zinthu zolemera
Nangula wa manja ndi chomangira chomwe chimangirira zinthu ku konkriti kapena makoma a njerwa.
Zimapangidwa ndi wononga nangula wokhala ndi nsonga yoyaka. Nangula wa manja amalowetsedwa mu konkire; Nangula amalowetsedwa kuti akulitse mkonowo kunja. Anangula a manja ndi pulasitiki kapena zitsulo.
Nangula zamanja ndizomwe zimasankhidwa pama projekiti akuluakulu.
Khwerero 1 - Sankhani nangula wa manja oyenera
Mtundu wa nangula womwe umagwiritsidwa ntchito umadalira ntchito yomwe ikufuna.
Ma nangula a pulasitiki otchipa amakhala olimba mokwanira kuti agwirizanitse zinthu zopepuka pamodzi. Koma zodzikongoletsera zolemera ndi zipangizo, zopangira zitsulo zimakhalabe zabwino kwambiri. Ngati simukudziwa kuti ndi iti yomwe mungagwiritse ntchito pantchito yanu, ndi bwino kugwiritsa ntchito nangula wamanja wachitsulo.
Kuti musankhe molondola kutalika kwa dowel-nangula, ganizirani makulidwe a njerwa ndi chinthu chophatikizidwa.
Muyezo wamba umagwiritsa ntchito nangula wa mainchesi 0.5 (1.27 cm) m'mimba mwake kuti atuluke pafupifupi masentimita 2.25 kukhoma. Mukhoza kutsatira ubale womwewu, kapena kuyerekeza kutalika kofunikira poyesa makulidwe ophatikizana a chinthu ndi khoma.
Gawo 2 - Mark Hole Malo
Nangula wa sleeve ndi wapadera chifukwa amatha kuikidwa m'magulu amatope kapena mwachindunji pamaso pa njerwa.
Mtunda pakati pa nangula ndi chinthu chofunikira kwambiri pokonzekera kuyika mabowo. Nangula ya manja imapanga katundu wodabwitsa pa njerwa. Kuwayika pafupi kwambiri kumapangitsa njerwa kuti iwonongeke pang'onopang'ono chifukwa cha kupsinjika maganizo.
Mtunda wofunikira pakati pa nangula uliwonse ndi ma diameter khumi.
Mwachitsanzo, danga lofunika pa nangula wa 0.5" (1.27 cm) ndi 10 x 0.5" = 5" (12.7 cm).
Mtunda wofunikira pakati pa nangula ndi m'mphepete mwa zinthu zomwe ziyenera kulumikizidwa ndi ma diameter asanu.
Khwerero 3 - Boworani mabowo ndi Hammer Drill
Kukula kwa chipilalacho chiyenera kukhala chofanana ndi nangula.
Kuzama kobowola komwe kumafunikira kumawonetsedwa muzambiri zamakina a nangula. Manja ena a nangula ayenera kukhala akuya kwenikweni. Ngati chidziwitsochi palibe, boolani 0.5 mkati (1.27 cm) mozama kuposa kutalika kwa manja a nangula.
Dulani chinthucho (ngati chilipo) ndi pamwamba pa njerwa mpaka kuya kwakuya kufikire.
Khwerero 4 - Chotsani Bowo
Imani nthawi yomweyo ngati muwona fumbi lambiri kapena zinyalala mu dzenje lobowola. (1)
Chotsani nkhonya ndikusiya dzenje lopanda kanthu. Tsukani dzenjelo ndi mpweya wothinikizidwa kapena payipi pansi ndi madzi. Ngati mwasankha chomaliza, sungani nsanza kuti muchotse chisokonezo.
Yambitsaninso kubowola mwamsanga pamene palibe zinyalala.
Khwerero 5 - Ikani manja a nangula
Ikani dzanja la nangula mu dzenje lobowola.
Iyenera kukhala yolimba mkati, osati kuzungulira kapena kuzungulira. Gwirani dzanja la nangula pang'onopang'ono ndi nyundo mpaka itasungunuka ndi pamwamba. Kenako amalowetsa bawuti pakati pa tchire.
Khwerero 6 - Limbikitsani Zopangira Nangula
Limbani wononga nangula mpaka ifike kumapeto kwa mkono.
Gwiritsani ntchito wrench yoyenera kapena screwdriver kuti mutembenuzire screwdriver. Kuchitapo kanthu kumakankhira dzanja kuti ligwire m'mphepete mwa dzenje. Pitirizani kutembenuza wononga nangula mpaka itakhazikika pamwamba pa njerwa.
Malangizo ndi zidule pokhomerera msomali mu njerwa
Tsopano popeza mukudziwa yankho la funsolo, mungakhomere msomali mu njerwa, apa pali malangizo ndi zidule zochepa zomwe muyenera kukumbukira.
Vuto lofala pokhomerera misomali mu njerwa ndi kukula kolakwika kwa zomangamanga.
Njira ina yabwino ndiyo kubowola pang'ono kusiyana ndi misomali yamiyala kapena ndodo zomangira. Bowolo likhoza kukulirakulirabe pamene zinthu zimayendetsedwa mu njerwa. Ingogwedezani nyundoyo ndi mphamvu zokwanira kuti mukhomereze zinthuzo mu dzenje laling'ono.
Yesetsani kuti musagwiritse ntchito kubowola kwakukulu chifukwa ndikovuta kutseka dzenje kusiyana ndi kulikulitsa.
Fumbi ndi zinyalala zochokera ku njerwa zoboola ndizowopsa kuzipuma. (2)
Dzitetezeni povala zida zoyenera zodzitetezera. Magalasi ndi chigoba chabwino cha fumbi (makamaka mtundu wa N95) ndizokwanira pulojekitiyi. Njira ina yochotsera fumbi ndi zinyalala ndiyo kuthira payipi nthawi zonse. Kuchita kwa madzi kumapangitsa kuti tinthu ting'onoting'ono tilemere ndikulepheretsa kuti tiyandamale mumlengalenga.
Onani zina mwazolemba zathu pansipa.
