Abstract
A spacer for a reinforcement bar to be embedded in concrete has a band-like member adapted to wrap around and encircle the reinforcement bar and formed at its ends with a pair of screw parts with external formations which form a screwthread when the two parts are brought together to cause the band to encircle the reinforcing bar and a base with a correspondingly threaded bore at one end is threaded onto the resulting screw to cause the clamping member to seize the reinforcing bar and mount the base on the reinforcing bar.
Claims10
A spacer for a reinforcement bar to be embedded in concrete, comprising:
- a band-shaped clamping member configured to encircle a reinforcement bar and provided at opposite ends with respective screw parts having inner faces and outer faces with screwthread formations, said clamping member having a flexibility enabling said screw parts to be brought together with said inner faces juxtaposed with one another upon said clamping member encircling said bar as a ring, whereby said screw parts form a screw and said formations constitute an external screwthread;
- and
- a base formed at one end with an internally threaded bore receiving said screw and with an internal screwthread mating with said external screwthread, whereby threading of said screw into said bore and said base onto said clamping member clamps said member against said bar.
