General zofunikira za chubu zosapanga dzimbiri
GB / T19228-2011 zachokera GB / T12771-2008, kotero zotsatirazi zofunikira ukadaulo zimagwiranso ntchito pazinthu zina zopangira zosapanga dzimbiri zitsulo chubu.
Ⅰ. Kukula ndi Kulekerera
Kuzungulira: m'mimba mwake wakunja kupatuka kololeka C ndi ± 0.5% D, DN150-300, 0.75% D pansipa DN150;
Makulidwe: Kupatuka kololeka: ± 10% S;
Kutalika: 3000-9000mm, ikhozanso kusinthidwa malinga ndi momwe zikufunira, kupatuka kololeka: 0 ~ +20 mm;
Kupinda Digiri: 2mm / M;
Kutsetsereka: Kutsetsereka kwa doko lachitsulo chitoliro kuyenera kukwaniritsa zofunikira pagome lotsatirali.
Ⅱ. Njira Yowerengera Kunenepa
Chitsulo chosapanga dzimbiri chimaperekedwa molingana ndi kulemera kwake, ndipo imatha kuperekedwanso molingana ndi kulemera kwenikweni mutakambirana. Mukaperekedwa molingana ndi kulemera kwake, kulemera kwake kumayesedwa malinga ndi chilinganizo (I)

Zosapanga dzimbiri zitsulo Chitsanzo chubu
- Chitolirochi chimagwiritsidwa ntchito ngati chubu kapena chubu chazomwe chimagwiritsidwa ntchito ngati ma handrails kapena zokongoletsera, zomwe zambiri zimakhala zosapanga dzimbiri zosapanga dzimbiri zosapanga dzimbiri kapena zabwinoko. Njira zake zopangira ndikuti kukanikiza kachubu koyamba ndi chitsulo, kenako kuwotcherera kwathunthu, ndipo pamapeto pake kumawaza ndi kupukuta.
- Kawirikawiri ndi mtundu wa daimondi kapena wozungulira, wotengera chitsulo chopangira chitsulo ndi chitsulo chachitsulo chopangira.
Makulidwe ake amakhala 22mm-48mm, ntchito yayikulu: zokongoletsera nyumba, masitepe oyimitsira ma handrails, ma payipi amizere, zoyendetsa galimoto, ndi zina zambiri.

Zosapanga dzimbiri zitsulo Handrail chubu, Wall Handrail chubu, Handrail chubu kwa Olumala
Izi zili ndi kapangidwe katsopano komanso ukadaulo wotsogola. Malinga ndi mawonekedwe a handrail, kuphatikiza koponyera ndi chitoliro kumatsimikizira kuti chovalacho chimakhala ndi mphamvu yayitali komanso mizere yosalala. Njira yolowera pamanja imathetsa vuto lomwe ngodya zina zitatha kuwotcherera pamanja sizingatheke. Malinga ndi zofunikira zaukadaulo, mawonekedwe apamwamba a handrail amatha kuchiritsidwa ndi burashi, kuphulika kwa mchenga, knurling, kupopera utoto, ndikuthira kutsitsi. Pambuyo pake, malowa amathandizidwa ndi njira yapadera yolimbana ndi kuipitsa, ndikupangitsa kuti ikhale yokongola, yopanda mafuta komanso yosavuta kuyeretsa. Njira yapadera yowotcherera yopangira dzanja imawunikidwa mozungulira kuchokera kumagwiridwe antchito, zida, ndi magawo amachitidwe kuti awonetsetse kuwotcherera.
