Structural chubu:

Structural chubu ndi chubu chachitsulo chokhazikika, chomwe chimatchedwa structural chubu. Ndi yoyenera kwa machubu opanda zitsulo osasunthika pamapangidwe ambiri ndi makina amakina. Zinthu zambiri ndi mpweya zitsulo, amene akhoza kugawidwa mu mitundu iwiri: wamba mpweya structural zitsulo ndi apamwamba mpweya structural zitsulo. Pali zambiri zomwe zimagwiritsidwa ntchito komanso kugwiritsa ntchito kwambiri. Amagwiritsidwa ntchito kwambiri mu njanji, milatho, ndi ntchito zosiyanasiyana zomangamanga kupanga zigawo zosiyanasiyana zachitsulo zomwe zimanyamula katundu wosasunthika, komanso mbali zosafunika zamakina zomwe sizifuna chithandizo cha kutentha ndi ma weldments ambiri.
Machubu osasunthika ndi machubu achitsulo omwe amagwiritsidwa ntchito pomanga nyumba zosiyanasiyana chifukwa amagwiritsidwa ntchito pomanga nyumba zosiyanasiyana zomwe zimafunikira kukwaniritsa zinthu zingapo.
1. Mphamvu yonyamula mphamvu iyenera kukhala yabwino, ndipo palibe kupasuka komwe kungachitike, mwinamwake, ngozi ikangochitika, kumangidwa kwa polojekiti yonse kudzakhudzidwa.
2. Zosavuta kumanga. Imangofunika kumangidwa molingana ndi muyezo wamba, ndipo imatha kumalizidwa mwachangu.
3. Chokhazikika, chikhoza kugwiritsidwa ntchito kwa nthawi yaitali polojekitiyo ikamalizidwa, ndipo sichidzawonongeka ndi kuvala kwa nthawi yaitali.

Fluid chubu:
Muyezo wa chubu wamadzimadzi ndi woyenera pamachubu achitsulo osasunthika otumizira madzi. Machubu opanda msoko ndi mapaipi achitsulo omwe amagwiritsidwa ntchito kunyamula zakumwa ndi mpweya wosiyanasiyana monga mafuta, gasi, gasi ndi madzi. Chifukwa chakuti amagwiritsidwa ntchito poyendera, mapaipi amadzimadzi alinso ndi mawonekedwe awoawo odabwitsa.

1. Kutsekeka kwa mpweya wabwino, palibe kutayikira komwe kumaloledwa panthawi yoyendetsa, apo ayi mpweya udzatuluka, ndipo zotsatira zake zidzakhala zoopsa.
2. Pewani kuwononga, chifukwa zinthu zambiri zonyamulidwa zimakhala zowononga, ngati zowonongeka, polojekiti yonse idzakhudzidwa.
3. Kusalala kwa chitoliro kumakhala kovuta kwambiri, ndipo kumafunika kukwaniritsa zofunikira musanapangidwe kukhala chitoliro chamadzimadzi.

Choyamba, kunena mosamalitsa, sangathe kugawidwa. Machubu omangika amafunikira mphamvu yotha kupirira bwino, pomwe mapaipi amadzimadzi amafunikira kusindikiza bwino. Choncho, ntchito ziwirizi ndizosiyana kwambiri. Yesetsani kuti musagwiritse ntchito malo olakwika.

Kachiwiri, mapaipi opangidwa amakhala ndi zofunika kwambiri pamtengo, apo ayi machubu ena achitsulo sakhala olingana ndi kukana kwa dzimbiri kapena mphamvu yonyamula mphamvu, ndipo amawonongeka mosavuta. Ngati madzi ndi chakudya zimayendetsedwa ndi mapaipi amadzimadzi, zofunika zaukhondo zimakhala zokhwima. Ikhoza kugawidwa pazochitika zapadera, ndipo zina ndizofanana, malinga ngati zofunikira zachilengedwe sizili zovuta kwambiri, zikhoza kugawidwa.
