Abstract

In a prestressed concrete railway sleeper whose sleeper body (1) consists of two supporting bodies (2, 2') carrying the rail fastenings and a centre part (3) of smaller cross-section, the prestressing elements (4), such as, for example, steel bars, wires or strands, starting from a point where they are united in a vertical and/or horizontal plane in the sleeper centre, are run radially and rectilinearly to the sleeper ends (5, 5'), where they are anchored in uniform distribution over the cross-sectional areas of the sleeper ends. By the uniting of the prestressing elements (4) in the sleeper centre, the use of a sleeper body having a narrow, high centre web and wide sleeper ends also becomes possible for prestressed concrete sleepers, in which sleeper body only slight alternating bending moments arise in the centre part or a unidirectionally positive pattern of the bending moments can be permitted over the entire length of the sleeper. <IMAGE>
