Nyumba zomanga njerwa zoyamba zinayamba kuonekera m'nthawi za m'Baibulo. Zoona, poyamba zinthu zosavulazidwa zinagwiritsidwa ntchito, koma mofulumira anthu anazindikira kuti atakonzedwa ndi moto, mawonekedwe a dothi amawonjezeka kwambiri. Pang'onopang'ono, mawonekedwe a njerwa anasintha, anayamba kukhala angwiro, okongola. Zojambula zojambulazo zinapangidwa, ndipo nyumba zomangidwa izi zinakhala zojambula zenizeni. Popeza masiku a Mesopotamiya ndi Roma wakale zambiri zasintha, komabe ngakhale tsopano nyumba zomangidwa ndi ambuye abwino a njerwa zam'kasu kapena zachikasu zimakhala zokondweretsa maso monga nyumba zomangidwa ndi pulasitiki kapena mapaipi .
Kodi mungasankhe bwanji njerwa yoyang'ana?
M'magaziniyi, muyenera kulingalira magawo otsatirawa:
- kukula kwa njerwa yoyang'ana;
- mtundu wa nkhani;
- yang'anani njerwa chifukwa cha zofooka;
- mphamvu;
- chisanu kukana;
- zotenthetsa.
Zonse za njerwa zoonekera ndi zamitundu yonse - zonsezi zimapangidwa molingana ndi chikhalidwe chokhazikika. Pali zazikulu zitatu zazikuluzikuluzi:
- 250х120х65 mm;
- 250x60x65 mm;
- 250x22x65 mm.
Mtundu woyamba ukhoza kutchedwa chilengedwe chonse, umapitako, palimodzi pa chizolowezi chokhazikika, ndi poyang'ana. Yachiwiri (yopapatiza) ikhoza kuloledwa kokha chifukwa choyang'ana ntchito. Koma lachitatu la kukula likufanana ndi tile osati njerwa. Ikhoza kugwiritsidwa ntchito pokhapokha pomaliza ndege yabwino. Mudzazindikira mwamsanga kuti pali njerwa zozama, ndipo pali zolimba. Nkhokwe zili pafupi ndi mphamvu kwa anzawo, koma makoma awo ali otentha kwambiri.
Kuwoneka kwa nkhaniyo kungathenso kudziwa zambiri. Mukawona zowonongeka kapena zobisika zamagetsi panthawi yogula, zikutheka kuti zinatenthedwa. Koma mthunzi wa pinki umasonyeza mosiyana, njerwa yoteroyo imakhala yosakwanira mankhwala ochizira.
Kuwala kumakhala pa njerwa yoyang'anila kumatha kunena za momwe mungathere kukamwa kwa laimu, ndipo mabala oyera pamwamba pake amasonyeza kuti zolembazo ndi kusakaniza kwa mchere. Zikuwonekeratu kuti kusanthula kwa mankhwala sikungatheke kwa wogula mophweka. Choncho, yesetsani kugula njerwa yokongola yomwe ikuyang'anizana ndi mthunzi wowala kwambiri.
Kuwonetsera kwa nkhope za njerwa
Zolembedwa pazinthuzi zimapangidwa chifukwa, zimayankhula za mphamvu ya mankhwala. Kuphwanyidwa kwa mphuno kumatchulidwa ndi kalata "F" ndi ziwerengero zingapo kuyambira 35 mpaka 100, zomwe zimakhala zowonjezera, zogulira bwino. Mphamvu imatchulidwa ndi kalata "M". Mwachitsanzo, njerwa ya M25 sitingaitanidwenso makamaka. M50 tsopano ndi khalidwe labwino pakati. Ngati ndalamazo zikuloledwa, ndiye kugula njerwa ndi kulembedwa kwa M150, ikhoza kutchedwa chinthu chokhazikika komanso chodalirika. Ngati n'kotheka, fufuzani chitsanzo chimodzi kapena zidutswa zingapo ndi nyundo yowonongeka. Njerwa yofooka kuchokera ku zotsatirayo idzagawidwa pang'onopang'ono mpaka pang'onopang'ono, pamene wamphamvuyo idzagawidwa mu zigawo zingapo zazikulu, kapena ngakhale kukhalabe wangwiro.
Mtundu wa njerwa chifukwa cha nkhope
Kalekale, mtundu wa zogulitsawo umadalira makamaka dothi, chifukwa chake, ku Ulaya, nyumbazo zinali zowala kwambiri kuposa ku Russia. Masiku ano, onse amasankha zowonjezera zowonjezera, zokhoza kujambula njerwa mu mtundu uliwonse wa utawaleza. Choncho, ndi zophweka kubereka, monga kuyang'ana njerwa, kukhala ndi mtundu wa udzu, ndi njerwa zofiira. Zonsezi zimapangitsa kuthetsa malingaliro odabwitsa kwambiri. Mwachitsanzo, okonda akatswiri a zapamwamba ndi ovomerezeka adzayandikira mtundu wofiira kapena wabuluu wa facade, womwe umawoneka wokhazikika komanso wolimba. Ngati nyumba yanu ili pamtunda, ndipo mukufuna kuonjezera kuwoneka kwake, ndiye muguleni njerwa yamdima ndi mthunzi wokondwa - lalanje, pichesi kapena zina. Mukhonza kuphatikiza zojambula zosiyanasiyana, kuyesa, kugwiritsa ntchito mipata yonse yomwe ilipo lero pamakonzedwe a zochitika zamakono.
