Structural part with a body consisting of synthetic-resin concrete

摘要

In structural parts which exhibit a body consisting of synthetic-resin concrete, in particular concrete/polymer composite, and on which an essentially box-shaped frame consisting of metal is fastened by means of anchors, there is the problem that, upon setting of the synthetic-resin concrete, which is known to shrink, stresses appear in the frame, which result in said frame bending and warping. It is proposed to design the anchor, and to connect it to the frame, such that the frame is retained, at the location of the anchor, such that it can be displaced in its position with respect to the body in at least one shrinkage direction parallel to the surface or to the upper border of the body.
