what brackets can i use to fix sign on corner of building?

[Steve Broughton]

Paul the best option mate is to do what lots of signmakers do, find a local blacksmith and get them to do it.

Ok Steve

i’ll drag the yellow pages out 2morrow.

I take it something in the shape of a “U” is adequate for the job??

Soz for bothering you but i need to get this right 🙂

Thanks

Paul

hhmm trying to visualise exactly what you mean mate…
on a corner? etc i know the obvious but thinking its more than that…
ill try reply later but you will need more than an l or u shape… im sure 🙄

Rob all i have atm is a scetch of what they are after, basicaly they want the two signs be held off the wall by 6 inches and to overhang the courner of the wall by 6 inches so that both edges meet.a bit like wraping the sign around the courner but away from the wall. if that makes any sense. (trying to visualise it in my head and do maths at the same time hurts)
i’ll post a drawing tomorrow, as i dont have a scanner at home atm.

use 50mm x 50mm x 3mm angle iron duplicate the size of your panatrim frame. One of the frames needs only 3 sides as it can use the up right of the other frame at the corner meeting point. Use the same angle iron to fabricate a stand off frame i would expect that four would do, 2 either side. You need to fabricate a ] (3′ high 6” out ) you would also require a cross brace to run from the top corner against the wall to the diagonally oposite corner on the frame, this will help stop the frame saging. bolt these standoffs approximately 12” from the ends of the frame. If you get it made right the biggest pieces you will have would be the 6’x3′ frames to witch you could prefit your panatrim frames on the bench. Installation order would be mount stand off brackets on wall, bolt frame to standoff brackets, bolt corner joint together. then clip your sign boards in the panatrim.
i would of included a sketch but couldn’t include attachment, hope you can understand above its harder to explain than it is to make.

Hi Kevin

Yep i think i can visualise it. I’ll have a clearer head in the morning.

Thanks for the reply

Mort
an extra point to think about, having these panels on stand offs will greatly increase panel blow outs from either side, may be an idea to skin the frames internally with a 1/4 inch ply etc.
Just a thought

Good point 🙂

I’m not convinced that panels get blown out – more likely they are sucked out.

By this I mean the wind doesn’t get behind the sign and push the panel out – what really happens is that the wind passing over the front of the sign creates an area of low pressure in comparison to the slower movement of air behind a typical sign installation (This is the same principal as an aircraft wing in which the faster moving air passing over the wing causes the wing to lift due to the pressure differential above and below).

I would even argue that allowing the air to pass behind the panel by fitting the stand off brackets will help to equalise the pressure differential and lessen the chances of a panel popping popping out. If you fit a plywood backing to the frame you will prevent the passage of air over the back of the sign and increase the pressure differential making it more likely for the panel to be sucked out.

Best remedy is to fit both a top (hanging) and bottom rail to the panel to keep it in place while still allowing movement of the panel within the frame.

i was basing my line of thought on the fact if you do a shop front you have a wall etc behind it & yes you do get panels sucked or blown out as well when winds are high. However Mort is going to have a panel on each wall at 90 degrees to each other sitting on standoffs. This basically means the wind will be travelling up an alley way with the end blocked in, it will beable to go up, down or round the corner what ever it does it will bounce off the rear of the boards etc with the likely result of the panel stopping it eventually popping. Using the 1/4 ply fitted with secure fixings to the internal side of the angle iron will give it a secure panel to bounce off. Yes you will still have the possible chance of suction pulling the panel out but it won’t have the help of wind pressure behind the panel as well which you would have if the ply board wasn’t in place.

And i was hopeing for a easy Job 🙂

Thanks for the input guys i will have to give this some serious thought, now if only the customer will go for the stainless steel one curved around the wall i’m trying to push for 🙂
