Abstract
An elastomeric compression seal for sealing expansion grooves in bridges or the like. The seal comprises a plurality of congruently linked cells having vertical side walls and convex upper walls. The seal is characterized by a controlled collapse which prevents the convex upper walls from elongating upwardly upon lateral compression of the seal. This controlled collapse is accomplished by downwardly extending V-shaped walls connected at their upper edges to the vertical walls. As the seal is compressed, the V-shaped walls collapse such that their apexes are displaced downwardly. This downward force is transmitted to the central portion of the convex upper walls by vertical connectors to negate the tendency of the convex walls to distort upwardly upon compression.
