Structural joint
First Claim
1. An expansion joint for bridging an expansion gap between two parts of concrete slabs used in floor construction, the expansion joint comprising at least one anchoring dowel to anchor the expansion joint in the concrete slabs;
- wherein said at least one anchoring dowel bridges an upper portion and a lower portion of the expansion joint, at least one said anchoring dowel longitudinally extending over the full length of the expansion joint and meandering over the upper portion and the lower portion of said expansion joint, wherein said at least one anchoring dowel is a continuous bridging dowel directly connected at regular intervals at connection points to the upper portion and the lower portion of the expansion joint; and
wherein said at least one anchoring dowel has a V-shaped cross sectional front view and a V-shaped top view, created by a bend in the at least one anchoring dowel midway along the height of the at least one anchoring dowel.

Abstract
The present invention relates to an expansion joint to bridge an expansion gap between two parts of concrete slabs used in floor construction, especially in the manufacture of concrete floors such as for example in industrial floors. Such expansion joints are evidently required to take up the inevitable shrinkage process of the concrete and to assure that the floor elements can expand or contract such as for example occur by temperature fluctuations and resulting in a horizontal displacement of the floor panels vis-à-vis one another.
