Patio Awning

In the instructions it tells me find studs or joists to mount the brackets. Is this the same as a lintel? I wish to attach it to a brick wall of my house.

Thanks

Also the fixings are unllike normal bolt. Its a threaded pin not threaded bolt, with an outer cylinder casing, with slits down it on the pin end.

Fixing to studs or joists sounds as if they are thinking of fixing it to a wooden building. If that is the case, and your house is made of bricks, it should be plenty strong enough. I would avoid drilling into a lintel as it is probably reinforced concrete, fairly hard to drill, and you don't want to drill through the steel.

Are these fixing bolts like rawlbolts or shield anchors, so they expand when you wind the bolt in or tighten the nut?

These are intended for brick walls.

If the instructions are not clear you could do a lot worse than phone the manufacturer.

Thanks for the reply. Here is my drawing on the pin.

looks as if i need access to both side of brick to use these! the expanding ones sound like a good idea. Is the one in your picture one of them? I have seen them before.

I think the thing in your drawing is similar. If you tighten the nut down onto the pin, I think it will draw the pin, and hence conical nut, up, and it will expand the split section of the sleeve, as the cone tries to pull itself into the sleeve, thus making it grip the brickwork. Just drill a hole that is a fairly close fit to the unexpanded sleeve. Once the sleeve starts to grip it will not spin loosely. Some sleeves are held together with a twist of wire to help you get started.

You can then put e.g. a bracket over the exposed threaded end of the stud and fasten it down with another nut.


p.s. how did you draw it?

 

[danielbb]

So just drill a snug hole whack it in and tighten? I drew it using paint. I dont have it on me to take a photo.

 

[JohnD]

It won't hurt to put a big galvanised washer under the nut, you don't want it trying to bear directly on the brickwork as you tighten it.

 

[danielbb]

Yeah i think it has one on.I forgot about that. Ill get back to you tommorow. Thanks

 

[danielbb]

its up, lovely. I think the bottom bolts went into the lintel. They are rock solid. the two tops ones in the brick seem to pull them self out sort off. So i gave up trying to tighten them too much. Thats for the help

You could try changing the top ones for resin anchors .......there is no expanding force with these.ask @ your local builders merchant
