How to mount LCD on a circular pillar?

[kananfsa7]

Hi guys! I am thinking a way to mount my 55" Samsung LCD on a concrete pillar that is running in the corner of my living room. I've looked around and cannot find a mount with a circular base so I am thinking of getting a mount witb a pivoting arm with a shorter base that I can basically bend around pillar. Would this compromise the structural soundness of the mount? Also, would the apartment building come crashing down on my if my drilling of the pillar cracks it? )) here is a picture. Your feedback is appreciated!

Welcome to the forum!

There's a number of engineering solutions, but what would you think about something like this - the Sanus FMK056? You could secure the vertical panel to your circular pillar (with metal straps or other things), and it would provide extra support for the TV in the vertical direction. You wouldn't need to drill into your pillar at all.

I'd first check to make sure you're dealing with a real concrete column and not a composite. A real column will have re-bar inside that could make drilling a problem. I use a multi-scan to find hidden re-bar and power lines, etc.
Zirco makes a few, you'll need a good one that scans through concrete.
I like Adam's idea, if your wife will go along with the straps, or hire someone experienced to drill and use Tap-Cons or lead anchors.

here's the OP's picture:

Based on the photo I'd just put the TV on a corner stand in front of the pillar. What I would not do is drill into the pillar. The cost to repair when he moves won't be pleasant. It's not like you can use the old toothpaste in the nail hole trick.

Many thanks to Sholling, Its Phillip, Rickster71 and Adam for your feedback. Ive given up on drilling the pillar idea, although it would have definitely looked great. I will look around a little more to see if I can find a mount with a stand similar to the one Adam suggested but possibly with a lower profile stand.

You could buy steel rod that's long enough to bend around the column, making a large U-bolt. Thread the ends, use a regular mount (your choice) and tighten the nuts, using lock washers & nylock nuts. If you want to avoid damaging the concrete, you could slide some kind of jacket over the steel rods. It wouldn't require a lot of tension- the friction will keep it from slipping down and rotating.

Not sure I would use a steel rod, but I would try metal strapping material first. It is plenty strong enough if done properly, and a metal plate could be used to secure the metal strapping. It's not all all impactful in the room and shouldn't damage the pillar. Heck, even nylon stapping, which is readily available from hardware stores, is plenty strong enough for the lighter TVs used today. Probably even heavier ones. In fact, I would more likely go that route. Get a 2x2 piece of 3/4" plywood, cut four slotted holes in it, run nylon strapping through it, and put it on the pillar.

That would be cheap, and would work I would think. I think you could hang from it!

Then just use a standard universal mount with your TV.

The more obvious solution is to just use a ceiling mount. Have a pole drop from the ceiling with the TV mounted on it. Chief and others make this type of solution available.

 

[Rickster71]

Lots of good ideas.
It's difficult to tell from the picture if the two walls intersect the column or if there is any space behind it, when trying to get straps around it.

Why would steel rod not be a good candidate? It's cheap, the tensile strength is far more than adequate and it wouldn't need to be tightened so much that it would damage the column. Besides, once the TV is in place, the rods will be out of sight.

Just because it would be overkill I think, and it doesn't have the flexibility which may prove to be a pain if things are off a bit. That is, it will take some work to bend a steel rod around a proper radius to provide clearance which won't destroy the paint job and will be tight enough to grab the pillar properly.

Not that it won't work! It will for sure if done properly.

But, I would likely go with nylon strapping and a board first because not only is it really inexpensive, those nylon straps can handle hundreds of pounds of pressure without issue, which makes them a extremely easy solution. Like putting a belt around the column and tightening it up. Cheap, easy, and works. Likewise the board would just take a few 1" drill holes through it which would take just a few minutes to put in place.

The other drawback could be if the clearance between the post and the two walls are small, you may not be able to get that bent bar with straight length to reach the mounting plate around the post.

is this it?

so i get the basic idea of taking a square piece of wood securing it to the column with nylon strips and then securing the tv mount onto the wood. pardon my lack of knowledge of the terms but here are my questions:

1) what do i use to join the two ends of the nylon behind the pillar and then fasten it?

2) im not worried about messing up the paint on the pillar as long as i dont have to drill into it. should i use a glue to first glue the wood onto the pillar before fasten it with nylon strips?

english is not my first language so i am unfamiliar with some of the hardware terms. could you guys post a links to the pieces i will need to do the project?

i am very grateful for your help! this will save me a bunch of $$$.

I think this is what you are after. Didn't look to see what diamater posts it can mount to; that is your job for the day

project completed!!!

mtrycrafts thanks for your suggestion. The solution would have been perfect but way over my budget. After a month of research, I ended up installing the TV directly on the pillar. The pics are below. The mount has been on for a few days now is has been standing almost as tight as it was when I first installed it. I expect it will loosing as the weight of TV and moving of pivot arm changes the weight pressure. I will be keeping an eye on it. If necessary, I will run a belt of steel around mount base for more support. What do you gents think?

Hey, it seems to work How long are the bolts into the column? Thanks for the pictures. Now it seems you have lots of room to walk around the column in case the mount loosens to use something different.

I hope you own that place because you drilled into a major structural component of the building which, IIRC, is illegal without a structural analysis. The belt of steel will do nothing if you cause spalling of the outer part of the concrete. If you're on the top level, you're better off than if you're on street level.

I'm sure someone will try to let me know that I'm a PITA or over-analyzing everything again but, having studied architecture/engineering, it's not something that anyone should recommend. It's never a good idea to drill into structural components without consultation.

The bolts are 3.5 inches long; about 2.5 is inside the column. cheers!
