Bolting a bender stand to the floor

[rdn2blazer]

I used 4 REDHEAD brand 5/8 concrete ancors to mount my bender stand to my floor and they have been no problem what so ever. these ancors have been industry standard for years for a reason, because they work great IF you install them correctly.

the hole has to be a fairly snug fit where you have to pound them into the hole. you thread a drive bolt in a 4/5 threads then pound on the bolt head and drive the ancor all the way til its bottomed out. you should drill the hole to where the ancor is just a bit below flush with the concrete as it bottoms. dont forget the blow out the powder and fragments left in the hole.

then you pull that drive bolt out and use the tool thay make to drive the plunger down or even just a steel punch will do the same thing. you drive it till it changes its sound and it wont drive in anymore ofcourse. your done. ofcourse if you drill the hole crooked the ancor and bolts will be crooked too. so use care to keep the drill square in both planes. a little crooked is tollerable but not too much.

I cranked in mine to tighten with a 1/2 in ratchet using a 15/16 socket, bolt heads were 15/16. they are tight and my stand does not move in the slightest.

if you dont have a level floor you can use washers to shim under your stand base to level it a bit. I used a 4 hole bolt pattern so I could level it if I had too in both planes. if you only use 2 hole to mount it you will only be able to level it in one plane. use atleast a 3 or 4 hole pattern. will post pics of my base mounted as soon as I get a few pics.

gonna be mounting my bender stand in the new garage soon. What am I gonna need to drill the holes? Also, if I use 1/2" all thread, what size hole should I be drilling? how deep? most garage slabs are only gonna be 4" thick, right? Standard 'burbs house, circa 1968...

Find all the parts you are going to use including the anchors/epoxy, etc and then go to Home Depot and rent a decent hammer drill and buy whatever size bit the anchor package tells you too. Drill the holes 4" deep and install your anchors.

FYI some Home Depots carry Hilti brand stuff including drill bits and anchors. You just have to find them.

Hilti has a new style packet epoxy that is pretty sweet that I am using on my current jobsite. it is pretty sweet. You drill the hole 5" deep. You insert this little expoxy packet into the hole and then take an impact and twist in the special allthread they supply and 30 minutes later your good to go.

Also if you are mounting stuff to a high PSI concrete floor they make a bolt that you use an impact to drive in. Simpson Titan HD bolts. We used them on another job awhile back with high PSI concrete tiltup walls.

not trying to hijack a thread after I just asked a specific question... but wtf is the difference between a drill and a hammer drill. I had a chinese-made HD once... and now I have a nice dewalt drill. Frankly, the later is 100x better for making holes.

but wtf is the difference between a drill and a hammer drill.

a hamer drill pounds down and twist as you drill you may have a tap tap tap as someone is driling -- that is a hamer drill -- a hamer drill is the right tool for concrete

 

[jekbrown]

ahhhh ok. I have a Lowes and Homodepot pretty close... guess I'll have to see what they have for rent. What size bit am I gonna need? I'd think at least a 5/8".... but I dunno.

Bit size depends on anchor choice. Pick your anchor and then get the bit the anchors require. Pound in anchors require a bit the same size as the hole, epoxy anchors require a bit one size larger then the whole.

You will have to go to Home Depot to rent tools as I have not seen a Lowes that rents yet. Not all HD's rent either. Rental yards will rent to you too.

I have bought drop in anchors from Threaded Fastener. Drill the hole, drop the anchor in and set it with the tool. Leaves the floor flush when not installed.

 

[jekbrown]

got the bit, but like you said... Lowes doesn't rent tools. lol! The cheap hammer drill they had was $199... so yeah, renting sounds good! They had 5" pieces of all-thread complete with washers/nuts in the concrete accessories section, along with the 2-part concrete-anchor epoxy. Got everything I need now but the drill...

I am going to be building a bad ass workbench along one wall, I think I will wait to rent the drill until I have that figured out, because I'd like to anchor the legs of it in 'crete also to make it hella stable. Might as well only rent the drill once!

I've been told by a concrete guy that the epoxy made for bonding studs in is the better plan. Doesn't stress the concrete like the expending fasteners do, so the slab is less likely to break up around the holes.

Is that the same epoxy that killed that guy here in MA when the concrete slab fell on his car?

 

[jekbrown]

sounds like falling blocks of 'crete killed the guy... not epoxy.

thats the way to go. that way if you need to remove the bender stand you will not be tripping over pieces of all thread sticking out of the floor.

 

[Rob 85K5]

Also good to use in more than one garage.

Ummm Are you referring to the slab of concrete in a tunnel that fell on a car? It was a recently opened big highway project IIRC? If it is, then the answer is no. If you posted as a joke then it's a fairly obscure one

 

[jekbrown]

yeah, the flush ones prolly would be better... but to late now!

its no big thang, I could always use an angle grinder to cut them flush, center punch what was left, drill out 1/4" of the all thread and then patch the hole.

I spent less than $5 on the drop ins and the setting tool. Add the bolts or use the rod that you have already.

Call me on my cell 949 289-3243. I worked for Simpson Strong-Tie for 5 years as a sales rep in the epoxy/anchor division and know all about this chit. Simpson epoxy is far superior to Hilti and any other brand and is a lot less $$$$ than Hilti. If you still need help call me.
