Реферат: 27,013. Zucco, P. Dec. 6, 1906, [date applied for under Patents Act, 1901]. Girders and beams; reinforced concrete.-A truss for reinforcing concrete structures is formed from a rolled bar consisting of two parallel members 1, 3, Fig. 3, of unequal section and connected by a tangential web 4, one bar having a tangential flange 2 at right-angles to the web 4. The web 4 is sheared from the ends towards the centre, and the upper member 3 is bent upwards at an angle to the lower member, and then parallel thereto at the ends, as shown in Fig. 1. The flange 2 is also sheared at intervals, and turned up to form vertical members 5, which may be bent over the bar 3 ; transverse ties 6 are also clamped on the bars. For additional strength, a bar 8, Fig. 2, may be secured to the ends of the bar 3 ; or two beams may be tied together.
