Prestressed structural body which is fitted together using a plurality of precast reinforced-concrete compound units

摘要

The invention relates to a prestressed structural body which is fitted together using a plurality of precast reinforced-concrete compound units (2), can be connected at the joints (6) thereof by a setting filler and in the case of which tendons can be drawn into sheaths (4), which are concreted into the individual precast reinforced-concrete compound units (2), and braced there, it being possible to fill, in particular, the interspace between the sheaths (4) and the tendons with injection mortar. The invention provides that the sheaths (4) are connected to one another, beyond the region of the joints (6) between adjacent precast reinforced-concrete compound units (2), to form continuous pressure-tight ducts (8) for the tendons. <IMAGE>
