this really only applies if your building a new shop . i had some beams left over from a job to use for a frame jig-fabrication-machinery base. the tops of the beams will be even with the floor surface. on the ends and the center is a grid of 6 anchor points so i can bridge across or anchor direct to. i still have to weld some rebar to the beams to have better grip in the cement. the beams will have cement all the way around them. the holes have 5/8" stainless nuts welded to back side with a piece of pipe around each so it has a deep pocket to screw into. in the past ive had bent frames or damaged machinery to repair and having a good anchor point is like having a second set of hands. we leveled the beams with a transit and poured a pier under each end so they are square and even with the finish floor surface. alittle beyond the home owner type shop but if you have the means, the time to do it is before the floor is poured
Hello Skidmarks, a good idea for sure. Just want to point out the fact that stainless nuts and bolts tend to gall easily. I think some never sieze would be an important factor when installing bolts into the welded nuts. Also I would run a tap through each nut before using, due to the fact that the welding may distort the shape of the nut and threads slightly.
I sunk a few 1 inch threaded bosses (2 inch thread depth) in the floor of my shop before the concrete was poured, capped both ends with duct tape, welded to 3 ft X of rebar. they're pretty deep but show up on metal detector. If I need them they are there, chip out the concrete then install a plug when Im done. havent uncovered them yet.
i did the same thing in my old shop... damn things were quite useful... a couple years ago when i poured the floor in my new shop? totally forgot. sure wish i had 'em now.
A good idea but you don't have to be building a shop from scratch to do it. I built a flat, level platform to build my car on using beams from heavy duty pallet racks and anchoring them into 16" tall concrete blocks made from square frame cinder blocks (don't know the real name for them) stacked on top of each other and filled with concrete. I set them up on the floor and then leveled the beams on top of them before I poured the blocks full of concrete. I welded rebar anchors on to the beams to anchor them in the concrete. I marked the floor so I can set them back in the same position so I know it's level and the beams are parallel.
Excellent ideas, especially the "flush with the floor" I beams. Wish i had pput in a couple of those when I built my shop. Frank
I had a garage built with a real hard sloped driveway. When the slab was poured, I slid a piece of chain through the rebar. Then when I moved my truck out in the driveway, (no engine) I could use chains and come-a-long to move it in and out, and not have it shooting across the street into my neighbor's yard.
excelent, i had a similar idea, but not as good, the day i will rebuild my little shop/garage this will be done.
Ill post some pictures later when i get some of the equipment moved in . got a couple other things I made to help save room and be more productive
