How do I go about bolting something into a concrete floor?

Answer 1

To point other posts have been correct, except that you will need a special masonary bit to drill the concrete. When you buy it, as the person selling it to help match it to the size of the expanding anchor bolt.
All should go smoothly, probably about two to five minutes for each bolt, depending upon the power of your drill. If you like, you may start each hole with a smaller bit, it will take less muscle and help guide the larger bit, less chance of it dancing about before it bites in.

Answer 2

There are several ways to attach things to, and into a concrete floor. If the item to be fastened will not be under tension (being pulled on), you might try using an epoxy glue. You will want to have a strong bondable surface on the concrete, which means the concrete must be hard and not crumbling or chalky. You can etch the surface of the concrete with an acid (white vinegar will sometimes work – keep the surface wet for a half hour or so, and keep applying fresh vinegar until the desired depth and roughness of etch is reached). You can also prep the surface by sand blasting, or even wire brushing the surface. Remove all dust and loose particles from the surface, and make sure the surface is thoroughly dry before applying the epoxy. You can drill holes which will improve the anchoring effect of the epoxy. When applying the epoxy, make sure the epoxy thoroughly “wets” the surface, and hopefully soaks into the surface a little. Let the epoxy cure before testing the strength of the bond.

You can drill a hole (or series of holes) into the concrete and then use special fasteners for attachment. There are screws that actually thread into a properly sized hole, and there are expandable fasteners that increase their diameter as the fasteners are tightened. You can use a special anchoring cement to anchor threaded rod and then attach the item to the rod with nuts and washers.

There are also nails that can be driven through the item and into the concrete. These nails are extremely hard and actually punch a hole as they enter the concrete. These nails can be driven in with a hammer, or shot into the concrete with a fastening gun. Properly fastened, these nails are easy to use, and do a good job of holding items in place. You don’t want to use nails if the item will be holding a load (under tension).

I would suggest that you go to a very knowledgeable person in a hardware store or department and explain exactly what you are trying to do. That person will probably be in a position to suggest an appropriate fastening system or device.

Answer 3

There are actually several methods available to you.
You can drill the hole and use a tapcon screw.
You can drill a hole and use a redhead expansion anchor.
You can drill a hole and use an epoxy with a threaded rod.
You can chip out a section of the concrete floor and repour the floor with your anchor bolts embedded in the new concrete.

Answer 4

You could get an expansion bolt - drill a hole (with masonry drill) put in the expanding peice of the bolt and then you can screw the bolt into it and it expands and grips the concrete so it will never ever come out!

Answer 5

Drill a larger hole then your bolts are with a concrete drill bit into the floor with a hammer drill, then use a ''spreader / anchors'' that fits the hole and that will accept your bolt, your local hardware store can help you with the selection of bolts and spreaders / anchors

Answer 6

Drill a hole and use a Tapcon screw. Redhead makes them. Contact your local hardware store for the size drill bit to use with them. If it is something really big that you are trying to put down, then Redhead also make an adhesive system that goes along with other larger bolts that holds well.

Answer 7

the ideal anchor bolts are the 'club footed' or wedge anchor bolts. The table would be detachable, however the bolts will stick up. i think of two-3" is often what they require. in case you have thinner concrete you will would desire to apply super L brackets and tapcon screws to unfold the attachment rigidity out farther so as that they do no longer pull out.

Answer 8

Drill the floor and screw the bolt in x

Answer 9

Drill hole with masonry bit
Use expanding anchor bolt to fix down
Simple

Answer 10

If you have to ask how to do this basic job, you may be better off calling a tradesman in. Their can be all sorts of snags such as hitting steel reinforcing, or drilling through carpet and the thread picks up in your drill, thus ruining the carpet.
