A description is given of a displacement body in the form of a hollow profile comprising latticework and flexible sheeting, in the case of which the fastening of the sheeting with respect to the displacement body from patent... (Patent Application P 2119705.1) has been improved. The displacement body according to the invention is, as shown in Figure 1, also provided with a flexible sheet on that side of the latticework which is directed away from the concrete. The sheets on the outer side and the inner side are connected to one another and enclose the latticework between them. In the case of a latticework comprising a steel-fabric mat and flexible sheets consisting of plastic, good corrosion protection of the structural steel is thereby achieved at the same time. The displacement body is produced by in each case one flexible sheet being applied on both sides of the lattice work and connected, preferably welded, at selected points. Latticework and sheets are subsequently deformed together. <IMAGE> |
