Concrete help

[JetDriver]

However you want to interpret that- I'll take it!  I've bought a tire changer and plan on mounting it in the garage.  It seems like most every concrete bolt works by drilling a hole, dropping in a sleeve of some sort or another, then putting in the bolt, which then expands the sleeve and applies pressure to the sides of the concrete.  Works great.  My plan is to change my tires, then remove the tire changer and plug the holes with smaller bolts to keep the dirt out until I change the tires again next year.  My fear is that I have applied great pressure to the sides of the holes in the concrete, probably setting up hundreds of small cracks.  When I remove the bolts to uninstall the changer, a few "crumbs" will fall in the hole.  Over time, maybe 2 years, maybe 5 years, whatever, by installing/uninstalling, installing/uninstalling over and over again, my holes will become so weak as to be useless in securely holding the tire changer.  Any thoughts on that?  Any alternative solutions for installing the tire changer.  I can't leave it installed- I need the garage space.

My first thought was to mount those holes with chains on the bottom, so you can hook the tire changer to the ground. Turn buckels and chain come to mind. Holes have those covers or screw on caps for keeping them clean. They are big enough that if they fill with crub you can clean the out.

Your right, the bolts may become a problem some time in the future, but they cost almost nothing, and you can always just move them over and start again, no foul.

your cement is probably 4 inches deep.  drill all the way through to the sand below, mount your hardware in the floor then when done cover your bolts.  if sand and dirt get into the hole, get a wooden dowl and push the dirt/sand down deeper, or get an air compresser with a small enough hose to blow out the sand (don't forget to wear safety glasses cause you will get shot in the eye!!)

I have pondered the securing of my HF Tire Changer as well.  Right now it is bolted on a piece of diamond plate steel that I stand on when changing the tire, however I have considered securing it to the concrete floor somehow so that I could also move it when not needed to save space and get it out of the way.  I don't want to weaken the concrete mounting by removing and installing and end up having a Swiss cheese garage floor with all those holes.  I also considered a slide in receiver mount so my truck could be the securing point.   

I thought of cutting the concrete floor and installing metal tubing (like a receiver hitch) into the concrete to mount the tire changer to and remove when not needed... but have not thought that thru quite yet.

Until I find or devise a mounting system for it.... the diamond plate that I stand on will have to do.  But I will continue to watch this post......

I would drill holes and epoxy some steel threaded inserts in there.  That will be permanent.  Once you remove the changer you just replace the bolts to preserve the threads and you will always know where them bolts are for next time

I think you will find that those bolts will not be easy to remove.

Make the location of the bolts at a place where no tire will have to roll over And leave them.

After removal of the apparatus replace the washers and nuts.

something along this line?

would leave the bolt/nut above the surface

[eric in md]

 idea maybe ....  mount it on a reciever hitch in the back of your truck .. like your tow hitch .. weld the 2 by 2 square tubing long enough away from your tailgate . slide it in there use it take it out. o my

Use a threaded drop in anchor, just drill your holes the correct size to fit the anchors, drop in the
threaded anchors and set the anchor with a set tool ( smaller bolt will work for the set tool). These work great, I have them used them over and over again, I have small plastic plugs I leave in mine when not in use.  If you have a Fastenall store close by go in and talk with the help, they have every kind of anchor you need.

+1.  If your concerned about the bolt head doing damage to something you could use a cap screw or other rounded head fastener.

I'm liking the idea several of you have presented (or at least seconded) of a threaded sleeve epoxied into a hole drilled in the concrete.  It sounds like it would be long lasting because it doesn't work by applying expansion pressure.  I've been to several hardware stores and not seen anything like that.  What are those more typically used for?  If I can go in and ask for it by what it's known for, maybe I'll be more likely to find it.  Also, what kind of epoxy?  Gorilla glue or similar ok? 

[Chrisj CMA]

I would use a construction grade two part epoxy.....our local cash and carry has some its mighty tough.  Threaded sleeves shouldnt be hard to find......did you try ACE they tend to have the  best selection of the hardware stores around here.......next Id try Lowes, they have lots too

try a tapcon

http://www.concretefasteners.com/anchors-fasteners/tapcon-screw/pricing.aspx?gclid=CKmxwvjJq6QCFdj75wod_Flgcw

you just drill a hole a little undrsized, (the drill bit comes with them) then screw the tapcon screw in with a small impact hammer. if the hole gets loose or rounded, and it should not for a long time, fill it with epoxy and drill another set.

What the son did at his shop was.

1.  Drill till he hit sand, was about 5"

2.  Went to the hardware store here in town and got a 3" sleeve, threaded inside.  If this store doesn't have it, no one in town has it.

3.   Put a small threaded rod into the sleeve

4,  Got it in the hole where he wanted it and epoxied it in.

5.  Left the temp bolt till it was cured.

6.  Repeated above 3 more times, his has 4 mounting bolts.

7.  Remove temp threaded rod and get 4 Grade 8 cap screws.

8.  Get 4 fairly good sized washers, thick ones.

9,  Mount the unit, tighten it down and use it.

10,  Get done, take cap screws out, move changer, put bolts back in the hole.

PS:   Sleeve does not come up all the way to the top of the cement.

PPS:  If you have a 'Fastenal' store close by, go tell them what you want to do and they will come up with some real good ideas.

USE A RED HEAD ANCHOR, YOU JUST DRILL A HOLE IN THE CONCRETE AND PUSH THE ANCHOR WITH A WASHER AND NUT DOWN THRU THE PART YOU WANT TO HOLD DOWN AND THEN TIGHTEN THE NUT. IF YOU WANT TO REMOVE THE NUT THE ANCHOR WILL STAY IN THE HOLE IN THE CONCRETE,  YOU CAN PUSH THE ANCHOR DEEPER INTO THE HOLE BUT YOU CANT PULL IT OUT.  THE RED HEAD ANCHORS COME IN ALL SIZES OF BOLT SIZES AND LENGHTS. GET THEM FROM MENARDS-HOME DEPOT- FASTINAL

I know this is an "older" thread, and I'm probably way late, but I've been thinking about getting a tire changer, and ran across this method - I'll be building it into whatever tire changer I end up getting - scroll down the page, the changer can go into the receiver on your truck, which negates the need to bolt it to the floor, at all! If you don't have a welder, you probably have a buddy that does, and a few brewski's (or beverage of choice) will probably get it made for you...
