发明名称 Spacer for tension member
摘要 A tendon for use in prestressed concrete is made up of a plurality of individual elements such as strands of steel wire arranged in a uniform array around and spaced radially outwardly from a center point. A spacer for the tendon includes a star-shaped base formed by arms extending radially outwardly from a central part. The central part and the arms define triangularly shaped openings for receiving one or a number of the tension elements. An intermediate part is positionable within the triangularly shaped openings for separating the elements located within the opening. The intermediate parts have a radially extending web and a flange extending transversely of the web for dividing the opening into separate spaces for each tension element. During assembly, the base is inserted into the tension member for separating the tension element and then the intermediate parts are inserted for spacing the elements from one another. The spacers are intended for use at a change in direction point of the tension member and initially are assembled at a position spaced from the change in direction point and then are moved to the point.
