Relieve beam to fit garage door opener

[patriksod]

Hello!

I encountered an unexpected problem today when I was going to install my new garage door.

The track for the motor is too long and hits the beam that supports the roof. This means I have to saw out the beam about 10 cm up, and the width will be at most 25 cm to get the track plumb. So the question is, can I support the beam with some form of steel profile or smaller timber to widen the beam and restore the strength?

Some dimensions:

garage width 3050
transverse beam 195x45
longitudinal beam 145x45 x 6 pcs cc 550
posts 120x45 cc 600

the first transverse beam (195x45) is located 3000 from the garage door. Then it's 2400 to the next one and 2400 to the last one.

the longitudinal beams (145x45) have an overlap of 1800 mm

climate zone 3

I think I've included everything of interest.

Thanks in advance.

Could be an idea to buy a longer track for the gate. Sure, it costs a bit but it might be worth it. It doesn't matter if it's a little too long, you adjust the end position when you install it.

The motor rail does not need to be level. If you lower it at the back just enough so that it barely clears (I'm imagining a few cm margin) the open gate, how much do you need to cut from the beam then?

The motor rail doesn't need to be level. If you lower it at the back just enough so that it barely clears (I'm thinking a few cm of clearance) from the open gate, how much would you need to notch out of the beam then?

unfortunately, it doesn't clear now and it's mounted as low as possible at the front of the garage door.

As the track is positioned in the picture, can it pass under the beam?

 

[patriksod]

Yes, it can pass, but it can't stay since it hits the garage door. However, I solved the problem by placing a new beam a post back so I was able to remove the one seen in the picture.

OK, then it's settled. But I wonder what is hitting? The rail is on a profile that sits on top of the side rails. My center rail is about 4 cm above the top edge of the side rails and the gate doesn't protrude much above the side rails.

What you can't see in the picture is that it slopes steeply downwards so it lies below the highest point of the side rails.
