Building our new work shop and train room

Recommended Posts

RogerDat

Well finely got things settled so time to build while I still can. Took a year for the permit as Lapu Lapu was redoing the system and tax rate, and it caused a massive back up.

It is a 20'x30'  slab on grade, roll form welded steel frame, insulated partly (train room), with outside metal sheathing /inside hardy flex (train room) with electrical in conduct pipe on wall / steel outlet boxes.

Work shop will have jalousie windows on one wall, and a 6 foot wide roll up door, or a sliding door on one end. The slab is done, the trusses are built, and they will start on the end walls tomorrow.

Also due to the constant rain, I had to buy 2 20'x20' tents, and 6 tarps so they could get some work done.

Those little concrete thingies holding up the rebar are called 'chairs' in the US, metal, and can bought on line. Minimum 2-1/2' inches up off the bottom for 4" slab. Don't know what the 'slump' was when you poured. Or did you even record it? Maybe you don't have a cone.

Not really trolling, just having fun. Our 'cement ' walkways on the farm are all over the place, and no temperature rebar. Just a bunch of cement .

Complete waste of time and money but if it makes you feel better to use them, go for it.

Chairs are available on line in some countries, but could not find any here in PI, so i had some made. 2 1/2 inch for a 5 inch slab.

You place cement, not pour it in the trade talk, they did take 4 samples, and should be finished soon, it was 25000 psi spec.

I am a piratical engineer, self taught, so I mimic what i see in manuals, so rebar,, and chairs are needed.  This is my second build of this style building, the first was our home.

What size trains are you running? I have a very nice N gauge locomotive that I have had for a long time.

The easy way, and I've seen this on many youtube's of driveway and slab pours from the US, is to simply tie the rebar and leave it lay.  As the mix is poured, one guy in rubber boots with a hook goes along the edge of the fresh mix and gives the grid a tug.  You can put it halfway if you want but less is ok, as long as the mix can get around the bars and it isn't too high in the slab it's no problem.

I have seen the vids of the mesh puller men, but  I shudder thinking how to explain to locals what to do. The slab workers are supplied with tools from the cement co., CSI, to finish the placement, and results are great. The idea of placing the rebar at least 2 inches inside the cement is to stop corrosion. also, the chairs help keep the rebar in proper place, center of 5 inch slab.

My train is HO scale, it will be my 3rd layout, 1 in us, 2 here.

That works fine .... but if you are doing a pour and under the pump the chairs just make it easier ...one less thing to frig about with ...:D

I guess it depends on the size of the crew but with cheap labor here it wouldn't be much to have one guy who's only job is the rebar depth.

And keep in mind , other than the Phils we use mesh , which is at 8" centres and the chairs enable a more consistent height of the the steel overall , which adds to better integrity/strength with eveness...

So engineering is all dependent on location and materials , but I like chairs because usually it is just me and my son and in go's the wet grey stuff with me on the screed and son on the shovel ...is it beer o'clock yet... :D

The videos I was referring to were US driveway pours with rebar grids.  I haven't seen much mesh used here except the 2" mesh and that's usually for fencing.
