For so long I have just used the simple, slopes/arches with beam technique for spanning large areas to create room ceilings or roofs. BUT NO LONGER! I have not seen anybody else use this so I may the first =) So here it is...
About this creation
The parts laid out, ready for assembly.
The parts assembled.
The structure, with a gap of 12 studs from side to side.
The beam fitted into the structure.
Once the beam is fitted, cover with 1 layer of standard plates. Please note, I left a 4x6 gap for a ladder to fit in.
My example ladder, no biggy.
Ta-da! The finished result. A simple, and yet cunning way to span gaps and still leave a hole for a ladder...or whatever else you may want.
I'd imagine this technique could probably be used for different size areas to.
Please feel free to rate and comment. If you have any further questions, I'll be happy to answer them too.
