How to Hold Heavy Things from Steel Reinforced Concrete Beams

You may have some building: garage,storage facility,country cabin...with a ceiling showing the concrete beams. You´re in for trouble if you want to hang something bulky and/or heavy from them. You shouldn't make messy holes in the beams or in the bricks supported by them: It´s something you´d always be sorry for. MAKE A CHEAP AND SIMPLE CLAMP that will solve your problem.


  1. 1
    Draw a cross section plan of a beam and take some measurements:
    • a) base of the beam: determines lengths of threaded rods and pipe.
    • b) short horizontal part of the right angle: ( these two bits) do the holding job of the clamp
    • c) long vertical part of the right angle going from the vertex to the tip of longest side: supports the threaded rods and pipe

  2. 2
    At a hardware store buy: a bar of iron 3 centimeter (1.2 in) wide, 0'5 to 0'7 centimeter (2.8 in) thick and about 1,000 centimeter (393.7 in) long. Also buy a length of threaded rod ( 50 cm ), plus 4 self braking nuts and about 25 centimeter (9.8 in) of iron or copper pipe that fits around the threaded rod.
  3. 3
    Now get the bar of iron and mark measure "b". Give it a few goes with the iron saw so that it'll make a nice right angle when you bend it in the vice using the hammer. Smooth everything with the grinder.
  4. 4
    Drill the first hole "a" cm measured from the long inside part of the R. angle, allowing some mm margin from beam base "a"for the diameter of the threaded rod.
  5. 5
    About 4 or 5 centimeter (1.6 or 2.0 in) from the first hole, drill the second and do the same for the third one.
    • The other part of the clamp is just the same except that it has just two holes.
  6. 6
    Cut the length of tube about 5 mm longer than "a".
  7. 7
    Cut the 2 threaded rods "a" cm long, plus 2 widths for the iron bars and 3 widths for the nuts.
  8. 8
    Assemble all the pieces at the very spot you want to use the clamp. The extra 5mm of the pipe and the threaded rods do the gripping job of the clamp on the beam. Also see it used in place at Make a Huge Hanging Shelf for a Cabin or Shed.
