Kodi zitsulo zagalasi zimafunika njanji yapamwamba?

Mkonzi: Onani Mate Onse Magalasi Olankhulira

Kufunafuna mawonekedwe osatsekedwa kumapangitsa kuti zitsulo zagalasi zopanda chimango zikhale zotchuka, koma malamulo achitetezo nthawi zambiri amafuna kuti zitsulo zapamwamba zikhale zogwirira ntchito. Apa ndi pamene zimafunika komanso momwe mungagwirizanitsire bwino:

Kugwiritsa Ntchito Masitepe:

Kutsatira Malamulo a IBC 1014/ADA 505: Masitepe aliwonse okhala ndi zokwezera zitatu kapena kuposerapo amafunika njanji yopitilira, yogwira yomwe ili mainchesi 34 mpaka 38 pamwamba pa mphuno ya masitepe. Galasi lokha silingagwiritsidwe ntchito ngati chogwirira; njanji yothandizira ndi yofunikira.

Malo Amalonda/Anthu Onse:

ADA ikufuna kuti njanji zapamwamba zigwiritsidwe ntchito kuti anthu ogwiritsa ntchito mipando ya olumala akhale otetezeka.

Malamulo a boma (monga California CBC) nthawi zambiri amawonjezera lamuloli ku madesiki okhala ndi malo opitilira mainchesi 30 kuposa kalasi.

Malamulo a Kutalika kwa Mzere wa Mzere wa Mzere:

Pamene njanji zapamwamba sizichotsedwa (monga, pa malo otsetsereka), chotchinga chagalasi chiyenerabe kufika kutalika kwa mainchesi 42 (IBC 1015).

Kodi Mungasiye Liti Sitima Yapamwamba?

Ma Decks Okhala Pamwamba ≤30″

Kutalika: Galasi lopanda chimango lingakhale lokwanira ngati chotetezera (sichingagwirenjanji yofunikira) ngati:

-Ma code am'deralo amalola (tsimikizirani kuchotsera kwa malamulo).

- Kutalika kwa galasi kuli pafupifupi mainchesi 42 kuchokera pamwamba pa deck.

-Mapanelo amapambana mayeso a 200-pound pa phazi lililonse (ASTM E2353).

Mayankho Osaoneka: Kuphatikiza Ma Rail Apamwamba Popanda Kuwononga Mawonedwe

Zipewa Zachitsulo Zokongola: 1.5–2 mainchesi m'mimba mwake, machubu 316 achitsulo chosapanga dzimbiri omangika pa malo oimikapo zinthu osabisika.

Ubwino: Imapereka malo ogwirika mosavuta pamene ikusunga mawonekedwe owoneka bwino okwana 90%.

Makina a Pin a Mutu wa Countersunk:

Ma rail apamwamba amamangiriridwa kudzera m'mapini opindika obooledwa m'mbali mwa galasi (osati zomangira pamwamba).

Chofunika Kwambiri: Imafuna galasi lofewa la 12mm lokhala ndi mabowo opukutidwa bwino komanso odzazidwa ndi epoxy.

Ma Channel Otsika Kwambiri: Ma Channel a aluminiyamu okhala ndi mawonekedwe a U (okutidwa ndi ufa kuti agwirizane ndi galasi) amasunga njanji pamwamba pa m'mphepete mwa mapanelo.

Kutsatira malamulo: Kusunga malo okwana mainchesi 1.5–2 pakati pa njanji ndi galasi kuti zigwire.
