<p>The device has a platen (2) with keyhole shaped orifices for passage of dowel bars (4), and a damper placed between the bars and the platen, where width of a narrow part (6a) of each orifice is equal to diameter of each dowel bar. The narrow part is oriented along a single direction (D) for each orifice, and diameter of a large part (6b) of each orifice is higher than the width of the narrow part. Nuts (7, 8) have transversal dimensions lower than the diameter of the large part to pass the nuts inside the large portion after sliding the platen on a sliding plate (5) in the direction. An independent claim is also included for a pillar comprising a base platen.</p> |
