Kutanthauzira kwazinthu ndi kapangidwe kake
Nangula wa mawonekedwe 7 amatchulidwa chifukwa mbali imodzi ya bolt imapindika mu mawonekedwe a "7". Ndi imodzi mwa mitundu yofunikira kwambiri ya mabawuti a nangula. Kapangidwe kake kamakhala ndi ndodo ya ulusi ndi mbedza yooneka ngati L. Gawo la mbedza limakwiriridwa mu maziko a konkire ndikulumikizidwa ku zida kapena kapangidwe kachitsulo kudzera mu mtedza kuti akwaniritse kukhazikika kokhazikika.
Zida zazikulu ndi mawonekedwe
Zofunika: Nthawi zambiri amagwiritsidwa ntchito Q235 wamba mpweya zitsulo (mphamvu zolimbitsa, mtengo wotsika), Q345 otsika aloyi chitsulo (mkulu mphamvu) kapena 40Cr aloyi zitsulo (kopitilira muyeso-mkulu mphamvu), pamwamba akhoza kanasonkhezereka (kutentha-kuviika kanasonkhezereka kapena electro-galvanized) kuteteza dzimbiri.
Mawonekedwe:
- Kuyika kosinthika: Kapangidwe ka mbedza kumakulitsa mphamvu yogwira konkire ndipo ndi yoyenera kukonza zida zazing'ono ndi zazing'ono;
- Kutulutsa: Kulumikizana kwamakina pakati pa mbedza ndi konkriti kumakana mphamvu yokoka yokwera;
- Standardization: Imagwirizana ndi miyezo ya dziko lonse monga GB/T 799, ndipo zofotokozera ndizosankha kuchokera ku M16 mpaka M56.
Ntchito ndi zochitika zoyenera
Ntchito:
Konzani mizati yachitsulo, zoyikapo nyali zamsewu, ndi zida zazing'ono zamakina;
Nyamulirani zinthu zosasunthika, monga mafelemu omangira ndi mabulaketi a zikwangwani.
Zochitika:
Mainjiniya a Municipal (nyale za m'misewu, zikwangwani zamagalimoto), mafakitale opanga zitsulo zopepuka, ndi zida zapakhomo (monga mabakiteriya akunja a air conditioner).
Kuyika ndi kukonza
Kuyika:
Mabowo osungira pamaziko a konkire, ikani mazenera oboola 7 ndikuponya;
Limbani zida ndi mtedza ndikusintha mlingo pamene mukuyiyika.
Kusamalira:
Yang'anani kulimba kwa mtedza nthawi zonse, ndipo zosanjikiza zamalata zomwe zawonongeka ziyenera kupentanso kuti zitetezeke.
Gulani malingaliro
Sankhani zinthu molingana ndi katundu: Q235 ndi yoyenera pazithunzi wamba, Q345 ndiyoyenera kunyamula katundu wambiri (monga milatho);
Kutalika kwa mbedza kuyenera kukwaniritsa zofunikira za kuya kwa konkire (nthawi zambiri 25 kuwirikiza kawiri).
Kufananiza ndi kusankha kalozera wa nangula zazikulu zitatu
| Mtundu | 7-mawonekedwe nangula | Nangula mbale yowotcherera | Ambulera chogwirira nangula |
| Ubwino waukulu | Kukhazikika, mtengo wotsika | Mkulu wonyamula katundu, kukaniza kugwedezeka | flexible embedding, economics |
| Ntchito katundu | 1-5 tani | 5-50 matani | 1-3 matani |
| Zochitika zenizeni | Magetsi apamsewu, zopangira zitsulo zopepuka | Milatho, zida zolemera | Nyumba zosakhalitsa, makina ang'onoang'ono |
| Njira yoyika | Kuphatikizira + mtedza kumangiriza | Embedding + wowotcherera pad | Kuphatikizira + mtedza kumangiriza |
| Mulingo wotsutsana ndi corrosion | Electrogalvanizing (zachilendo) | Kupaka galvanizing otentha + kupenta (kukana kwa dzimbiri) | Galvanizing (wamba) |
Malingaliro osankha:
Zofunikira pazachuma: Nangula zogwirira maambulera zimakondedwa, poganizira zonse za mtengo ndi ntchito;
Zofunikira zokhazikika: Nangula wowotcherera mbale ndiye kusankha koyamba kwa zida zolemetsa;
Zochitika zokhazikika: Nangula wokhala ndi mawonekedwe a 7 ndi oyenera pazosowa zambiri zokonzekera.
