Houseboat Flybridge

[JohnHeart]

How do you connect the flybridge structure to the roof panelling 120mm thick?

Thanks.

I assume you are referring to the cabin top. What is the structure of it like? Also what is the weight of the flybridge?

[JohnHeart]

Yes. I am referring to the wheelhouse on the roof of the houseboat. I assume that the the flybridge will weigh 1 to 3 tonnes.

Do I need some aluminium pillars from the main deck connected to the roof to support it or some structure on wall panels?

Thanks

To figure out if it needs reinforcements, you got to tell me what the rest of the structure looks like. For example: beam, length, height, cabin side structural details, cabin top details, etc. Also, one to three tonnes is quite a range. If it is only one, building for three tonnes will cost you double than necessary.

two (2) A/c unit will be on flybridge. Railings which is 6.0mx4.3m LxW. The roof is 17.4mx5.2m by 120mm thick. A canopy with pipe structures will be welded on railings.

I think I have over estimated the weight. Maybe the maximum is 1-tonne. On the area of 6.0mx4.3m how much live load should I allow if this area is populated by people?

I am planning to put a fridge, barbeque grill, sink and helm station on this flybridge. I have already a helm station inside the superstructure on main deck.

Thanks.

Sounds more like a deck than a roof...
Allow 5kPa (500 kg/sqm) deck loading over the whole deck and self weight would normally take care of itself if following conventional techniques. 3 kPa could be used but the deck will most likely be "Springy" due to deflections. Most people don't like spring. Sounds a lot but really isn't. Oh if you load up to the full extent the vessel may still be unstable etc etc etc. The load is typical for what may occur locally but should be applied to the entire surface when designing structure.

Sounds like you may be best getting someone in your local area to do the numbers for you and give you appropriate advice.
