Questions & Answers
How far apart should rebar chairs be located? Should it be 6", or 12", or 18", or further??
Do you have to thread the bottom rebar through first, if 10 feet how many chairs to slide in?
The pic is deceptive. The chair is open to the bottom and top. I recommend twisting the chair onto the #4 rebar first (#3 drops in), then twisting the #4 rebar into the top of the chair (again #3 just drops in). While you can muscle # 5 into the top position only, I don't recommend it. To be clear I don't mean screwing, you just need a 1/4 turn to get the lip of the pocket past the ridge on the bar. After a full length of bottom rod (bar) is laid I go back and adjust the chairs to sit flat & properly spaced. With practice, you can set (twist/untwist) the top rod (bar) without having to go back. As far as how many you need, that depends on your matrix (grid spacing), which is either by spec.(plans/engineer/table/etc.) or by governing body (code/inspector/etc.). Unless you have (or access to) a machine that ties rebar together, I highly recommend these chairs (appropriately sized for your project) over wire chairs. They take a little longer when first using them, but you can quickly learn to not break them and be efficient in placing them. I find them to be an excellent way to keep hydronic lines closer to the surface instead of wasting precious BTUs heating the ground.
Will this product work with wire mesh?
I don't see why not. It's designed to hold rebar, but if the mesh sits symmetrically at a 4-corner point on the stand, it will certainly support the weight. Your goal with these is to just suspend the structural supports (whether rebar or mesh) from sinking to the bottom of the cement when it's being poured.
I doubt it would work with wire mesh. I think walking on the mesh would collapse the chairs. With rebar you can kind of walk inside the grid.
No.
It's designed for rebar but you could drop mesh on them. I personally wouldn't use them again. They are too tall and too fragile.
I was using rebar, but I'm sure it would work with wire mesh as well.
It is made for reinforcement bar. It could hold up wire mesh if you used enough of them and spaced them so the mesh does not sag. You would have problems if you walk on the mesh!
May we kindly know if you have the product data of this plastic rebar chair so that we could submit it to the owner/developer
Dear Valued Home Depot Customer, We have reached out to the manufacturer and their answer is, Here is a link https://herculeschair.com/data-sheet.phpto [herculeschair.com] our website with the Data & Testing information.
Pardon my ignorance; I have never worked with concrete and am researching. The product description and installation guide did not explicitly say that they get buried in the concrete but sort of implied it by saying that they are strong enough to hold up during the pour. Just want to verify whether or not these stay in the mix even after it’s poured.
They get buried in the concrete
They get buried in the concrete. They hold the rebar in place during the pour.
They stay in after the pour to make sure they stay in place while the slab cures.
Yes, they get buried - they are designed to lift up the rebar and tie wires off the ground so you get proper centering in the thickness of the pour. Note - you use the right model for the thickness of your pour.
They get buried in the concrete. You may want to check out the concretenetwork web site and the "Technical Information" tab.
Does the top steel finish at 1 1/2 inches from the base or the bottom steel
The top bar sits at two inches high the bottom one is at one and a half high
These are optimized for a 4" slab: the bottom of the lower rebar is 1.5" from the foot, the intersection of the two lengths of 1/2" rebar is therefore at 2", and the top of the upper rebar is at 2.5".
The 1 1/2 " Clearance is from the ground to the bottom of the lower bar.
Do you have em for 3/8 rebar. Or will these work
Yes, they will work. I am old school so I tied them down with steel tie wire as well. Made it easy to install rear and i got a lot of compliments about my slab.
I used on 3/8 rebar, sometimes tight to snap in, so they not only work for 3/8, might be preferable to something smaller.
I planned on using 1 1/2 runners with 2 #4 rebar to give me 2.5 inches to top of steel. Would these give me the same clearance
These are optimized for a 4" slab: the bottom of the lower rebar is 1.5" from the foot, the intersection of the two lengths of 1/2" rebar is therefore at 2", and the top of the upper rebar is at 2.5". So the overall height of the chair is 2.5" (with or without the rebar in it).
These are optimized for a 4" slab: the bottom of the lower rebar is 1.5" from the foot, the intersection of the two lengths of 1/2" rebar is therefore at 2", and the top of the upper rebar is at 2.5". So with a 4" slab there is 1.5" of untouched concrete both over and under it.
Yes, 1.5 inches to the bottom of the bar, #4 is .5 inch so 2" to the top of that bar and your crossing bar is another .5 inches to total from bottom of substrate is 2.5" Perfect for a 4" slab
