My shop is under construction

[Tractors4u]

Earlier this year we closed on 16 acres of property. The new house was started back in July and now for the importatnt part. My new shop was started this past Friday. It will be a 40' X 60' shop. Actually a 40'X60' slab with 40'X40' fully enclosed. On one end there will be a 20' section that will be a roof only. That will allow me to park the tractor there when it is muddy or store things under cover without bringing them in the shop. It will have a 10' roll up door on the other end. I am going to stub it out for a 1/2 bath and a shop sink. They will insulate it and once the house is finished I will run electricity to it. The builder said it would take them 7 to 10 days to complete. I am thinking that they will have it finished by this Saturday.

Attached is a picture after the first day. Posts in the ground.

Start of the second day. The truss guy had an old 1 ton Chevy truck with a hoist on the back. He had to assembly the boom and it lifted the truss using a winch.

At the end of the day Saturday they had all of the trusses up.

I was thinking it was going to be too small until I pulled my truck in there. Seems roomy enough.

Very interesting truss design. I was wondering if you were going to use wood and posts in the middle, or clear span the full 40 feet. Can you post a clear pic of one of the truss's?

I'd also like to see how they attached them to the poles if you don't mind. Those large spans just fasinate me!!!

Thanks for posting your project, I'm looking forward to your progress.

I will swing by this afternoon and get a close up shot of one of the trusses. It will be a 40 ft clear span, no posts getting in my way! I will also try to get some shots of how they are attached to the posts. I am not sure of the size, but it looked like they were about 3/4" lag bolts they were used to fasten the trusses to the posts.

Brent, my shop is 40X50 with a 15' awning on the 50' side. Shops are like tractors there maybe a day when you wished you went bigger.
Looks great so far.

Ah - a metal truss, and you obviously don't have snow load where you are. /forums/images/graemlins/smile.gif

Snow load? maybe a half inch.

And for Eddie Walker. Here is a close up of how the trusses attach to the post.

More of the truss.

It's a very interesting design. In my mind, I question how strong the attachments are. How many bolts are tying the truss to the post? Are they bolts that go all the way through, or lags? I only see two, is that corrct? What size and are they gavlanized? I've heard that the larger lumber is still PT in the old method that doesn't corode metal, but I don't know this for fact.

Your making great progress, thanks for the pics!!

Looks great Brent!

It looks like the top chord of the truss sits on top of the pole? I would think that that would be a good way to transfer the load to the pole instead of having it all bearing on those lag screws/bolts.

Were those trusses built locally or trucked in from Perka, Miracle Truss, etc?

Keep us posted!

Eddie,

I was going to post the same thing. In the picture, it looks like there is a flat piece metal at the top edge of the truss that rests on the top of the post. But it sure looks like just 2 lag screws are attaching the truss to the sides.

What would be great would be a metal cap on the post that the truss is either welded to or secured in some fashion to keep the shear force of the truss from taking out those 2 bolts plus prevent the truss from pushing the tops of the post outward under load.

Other than that, looks really good.

Good eye, yes the truss is resting on top of the post. The lag bolts just hold it in position.

I was asking the builder where he gets the trusses, they are manufactured locally. Actually he said there were quite a few manufacturers here in Alabama to get them from.

Here is where they were at the end of day 3. I worked with them today, I installed plumbing for the shop sink, bathroom, etc. I moved a lot of dirt and they put in insulation and most of the roof. Concrete will be poured tomorrow.

Everything looks just great Brent! I am sure that you are excited to see a nice big workshop go up.

If I could ask: I am curious what size angle iron they used in your trusses? I built this barn using metal trusses a couple years ago. As you can see, the design of the trusses is pretty similar to yours. In preparing for that shop, I did a lot of reading, etc and learned a fair amount about truss design and how to calculate compression and tension loads in trusses using finite element analysis. But my experience is still limited to that one barn (and a smaller one a couple years earlier). So I was just curious what sized angle iron was used in your trusses? From the pictures, it looks like maybe 1.5" by 1/8"?

Just curious about what the pros are doing compared to my blind attempts of the past!

I am not sure what size the angle iron, from memory, I would say you are close if not right on the mark with your estimate.

I went by this morning and made a couple of pictures of what it looks like after 4 days. The concrete truck should be there right now.

 

[Tractors4u]

Ready for concrete.

 

[Tractors4u]

Concrete was poured!
