Muhinduzi: Reba uwo mwashakanye Ibirahure byose
Ibintu byingenzi byubahiriza ibirahuri (igorofa, ingazi, cyangwa pisine):
1.
-Kurwanya Umutwaro Kubaho:
A 200-poundumutwaro wibanzegukoreshwa mu buryo butambitse ahantu hose (IBC 1607.7.1).
Aumutwaro umwe y'ibiro 50 ku kirengehakuryahejuruinkombe (ASCE 7-22).
Umupaka wo gutandukana:Kugarukira kuri L / 60 (urugero, ntarengwa ya santimetero 1 kuri metero 5) munsi yumutwaro.
Ikizamini:ASTM E2353 (ibyemezo byabandi-bisabwa).
2. Ibikoresho & IbihimbanoIbisobanuro
| Ibigize | Ibisabwa |
| Ubwoko bw'ikirahure | Umujinya (ASTM C1048) cyangwa urumuri (ANSI Z97.1) -min. Uburebure bwa 12mm. |
| Ibyuma | 316 ibyuma byo mu nyanja byo mu nyanja (ASTM F2090); aluminiyumu 6061-T6. |
| Kurangiza | Impande zometseho / zisukuye (nta gukomera kuri CPSC 16 CFR 1201). |
| Ingaruka z'umutekano | Ugomba gutsinda ikizamini cya 100mm (nta cyuho> 4 ″) kugirango wirinde kwinjiza abana (IBC 1015.3). |
Uburebure bwa Murinzi:
- Inzu yo guturamo:Santimetero 36-42 (IBC 1015.2).
- Ubucuruzi / ingazi:Nibura santimetero 42 (ADA 505.4).
-Ibisabwa hejuru ya Gariyamoshi:
- Ingazi:Gari ya moshi ishobora gufatwa hejuru, santimetero 34-38 z'uburebure, ni itegeko (IBC 1014.6).
- Urwego rwo hejuru:Gari ya moshi yo hejuru irahitamo niba ikirahure cyujuje uburebure nuburemere bwihariye.
- Umugereka shingiro:
- Anchor bolts ifite byibura diameter ya 1/2 santimetero, yashyizwe muri beto hamwe na epoxy (gushyiramo byibuze 3-cm).
4. Urubanza rwihariye: Kurinda ibirahuri by'ikirahure
-Kwishyira hamwe kwa Handrail:Ikirahure ntigishobora kuba nk'intoki; gari ya moshi itandukanye irashobora gukenerwa.
- Guhuza imigozi:Utilize kubara imitwehamwe na UV ihamye epoxy (urugero, SikaFlex® 295).
- Isahani ya Kick:Uburebure byibuze bwa santimetero 4 kurwego rwintambwe kugirango wirinde kunyerera (OSHA 1910.29).
5. Ingingo zananiranye
- “80% by'ubugenzuzi bwatsinzwe birimo:
- Ikirahure kidashidikanywaho (ukoresheje 10mm yometse aho gukoresha 12mm)
- Icyuho> kirenze 100mm hagati yikibaho
- Yononekaye ibyuma 304 bidafite ibyuma muri zone yinyanja
- Kubura raporo y'ibizamini by'abandi bantu. ”
Ibyifuzo byimpuguke
-Ahantu nyabagendwa:Koresha ikirahuri cya mmmm 15mm hamwe na 1.52mm ya PVB.
- Umuyaga:Mugabanye intera ya spigot kuri metero 1,2 cyangwa munsi yayo (ASCE 7 ikarita yumuyaga).
-Inyandiko:Komeza ibyemezo by'urusyo (kubirahuri) na ASTM F2452 (kubikoresho).
- Buri gihe utange ibishushanyo mbonera kugirango wemererwe.Ibikoresho bitubahirijwe bishobora guhanishwa amande arenga 5,000 $ kandi birashobora gukuraho ubwishingizi.
