Abstract

814,812. Reinforced concrete. KLOCKNER-HUTTENWERK HASPE A.G. Nov. 23, 1955 [Nov. 26, 1954], No. 33576/55. Class 20(4) A reinforcing bar for concrete which is of circular or polygonal cross-section and may be twisted or untwisted has a number of small raised portions arranged on its surface which are in the form of dogteeth or small stars and the distances between the centres of adjacent raised portions measured along a line parallel to the axis of the bar are not less than three times the greatest thickness or width of any of the raised portions. As shown in Fig. 2, two diagonally opposed rows of dog-tooth projections are provided and two diagonally opposed ribs. In Fig. 6, a hexagonal cross-sectioned bar has two rows of star shaped raised portions. In other forms the raised portions are arranged at the corners or on the sides of bars of polygonal cross-section and the latter may have concave side faces.
