Abstract

A rod chair has a tubular body of hollow frustum shape, i.e. a tapered body (30) with open ends (35, 42) to permit mutual stacking. The body has two pairs of diametrically opposed troughs (32, 36) in one or both ends thereof, with each pair having a different depth. Larger bodies have apertures (38, 40) to permit concrete to flow therethrough. The troughs (32, 36) and apertures (38, 40) are arranged on the body (30) so that a continuous strip of body member material (43) extends in the longitudinal direction, either from end to end (35, 42) between adjacent troughs or from the bottom of each trough to the opposite end of the body. Also, some bodies have a continuous strip of material (45) provided in the circumferential direction intermediate the two ends (35, 42). The continuous strips of material (43, 45) provide strength against axial and circumferential forces respectively.
