Ma Handrails vs. Balustrades: Kusiyana Kwakukulu mu Malamulo a Chitetezo ndi Zomangamanga
1. Matanthauzidwe ndi Ntchito Zoyambira
Zogwirira ntchito:
Cholinga: Amagwiritsidwa ntchito makamaka pamakwerero ndi m'malo otsetsereka, amapereka malo ogwirira kuti athandizire komanso azitha kukhazikika.
Kapangidwe: Ayenera kukhala osasunthika, osalala, komanso osavuta kugwira, (ndi mainchesi ozungulira kuyambira mainchesi 1.25 mpaka mainchesi awiri, kapena ozungulira osazungulira kuyambira mainchesi 4 mpaka 6.25.
Chizindikiro cha Khodi: IBC 1014, ADA 505.
Balustrade (Chingwe Chomangira Khoma):
Cholinga: Amapanga chotchinga choteteza kuti asagwe kuchokera kumadera okwera (monga ma terraces ndi ma balcony).
Kapangidwe: Zimaphatikizapo zinthu zodzaza, monga magalasi, zipilala, kapena ukonde, ndi njanji yapamwamba.
Chizindikiro cha Khodi: IBC 1015.
2. Kusiyana Kofunika Kwambiri Kwaukadaulo
| Mbali | Chingwe chogwirira ntchito | Chingwe Choteteza (Guardrail) |
| Ntchito Yoyamba | Chithandizo ndi chitsogozo | Kupewa kugwa |
| Kufunika kwa Kutalika | 34″–38″ (masitepe/makwerero) | 36″–42″ (madesiki/mabalakoni) |
| Kugwira ntchito | Chofunikira (ADA 505.3) | Sikofunikira |
| Kukaniza Katundu | Makilogalamu 200 okhuthala (IBC 1607.7.1) | Makilogalamu 200 okhuthala (IBC 1607.7.1) |
| Zigawo | Mzere umodzi wopitilira | Njanji yapamwamba, nsanamira, zodzaza, njanji yapansi |
3.Kuphwanya Malamulo Ofala
• Kugwiritsa ntchito mipiringidzo ngati zogwirira (monga mipiringidzo ya sikweya yotakata kwambiri kuti isagwire).
• Mipata (Zogwirira ntchito ziyenera kupitirira mainchesi 12 (pafupifupi masentimita 30) kupitirira sitepe yapamwamba/pansi).
• Kutalika kosakwanira (malo otsetsereka a terrace balustrade a mainchesi 36 m'malo mwa mainchesi 42 m'malo ochitira malonda).
"80% ya zolakwika zowunikira zimakhala ndi mavuto a zogwirira. Chingwe chapamwamba cha mainchesi 4 m'lifupi sichimaonedwa ngati chogwirira pokhapokha ngati chapangidwa kuti chigwire."
— Katswiri wa Malamulo Omanga
Machitidwe Osakanikirana: Nthawi Yophatikiza
Pa masitepe ambiri okhalamo, njanji yapamwamba ya chogwirira ntchito ingathenso kugwira ntchito ngati chogwirira ntchito ngati ikukwaniritsa zofunikira izi:
- Mawonekedwe osavuta kugwira (monga ozungulira, mainchesi 2.5 m'lifupi kapena kuchepera).
- Kulumikiza kosalekeza popanda kulepheretsa zida.
Chitsanzo: Chogwirira chachitsulo chokhala ndi chitoliro chozungulira pamwamba (chokhala mainchesi 1.9 m'mimba mwake) chimakwaniritsa ntchito zonse ziwiri.
4.Malangizo a Akatswiri
Masitepe/Makwerero: Nthawi zonse ikani chogwirira chapadera komanso chosavuta kugwiritsa ntchito, ngakhale ngati chogwirira chatha kale.
Kusankha Zinthu:
Chogwirira: Gwiritsani ntchito matabwa, chitsulo, kapena zinthu zopangidwa ndi zinthu zosiyanasiyana zokhala ndi malo osalala.
Zogwirira ntchito: Zosankha zikuphatikizapo galasi, aluminiyamu, chitsulo chosapanga dzimbiri, matabwa, ndi zina zotero.
Chitsimikizo: Onetsetsani kuti dongosololi likutsatira ASTM F1677 (Handrail Grip) ndi ASTM E2353 (Structural Loading).
Nthawi zonse funsani ma code akumaloko. California CBC ndi Florida FBC zili ndi zofunikira zolimba kuposa IBC.
