ABSTRACT:
The assembly for bridging over expansion joints comprises sealing band of elastic material which bridges over the joint, which sealing band, for being secured in upward open cavities, includes thickenings substantially filling up said cavities and extending in joint edge profiles at both sides in the longitudinal direction of the profile. Said thickenings include a support surface engaging in the inserted position with an appropriate pressing surface of the joint edge profile, said thickening being wedged in the cavity by means of a bulge formed thereon. Said thickening includes a nose formed thereon, which in the inserted position is pressed together in a manner that in the marginal portions of the cavity between the thickening and the joint edge profile there is a contact pressure. Thus it can be avoided that under the effect of any forces there opens a slit between the sealing band and the joint edge profile, whereinto moisture or dirt may make their way.
