초록 ▼

A resilient, deformable, adhesive-free sealing strip for expansion joints in concrete comprises an elongated central core with a reinforcing web embedded therein. First, second and third pairs of fins extend from opposite sides of the central core, the first pair being shorter than the second and third pairs, the first pair disposed at the top of the strip and the second and third pairs being disposed at spaced intervals down the elongated core. Each pair of fins has a combined width greater than the width of the joint to be sealed. Upon insertion of the strip, the second and third pairs of fins are substantially deformed in the direction opposite insertion, exerting pressure against the concrete void walls, and through the central core, against one another, firmly locking the strip in place. The first pair of fins are only moderately so deformed, sealing the open top of the joint. In an alternative embodiment, the reinforcing web may be embedded in a collapsible, compartmented chevron shaped sealing strip, of the kind having side walls which are adhesively bonded to the walls of the expansion joint.

대표청구항 ▼

A resilient deformable sealing strip for expansion joints in concrete, comprising in cross-section: a vertically extending central core; a reinforcing web embedded in the central core, the web having a plurality of interconnected longitudinal and vertical members which inhibit compression and elongation of the central core; a first pair of fins extending outwardly and substantially perpendicularly from the top of the central core, having ends adapted to engage opposite void walls of the joint, the first pair of fins sealing the joint against entry of moisture and debris; and, second and third substantially identical pairs of fins extending outwardly and upwardly from the central core, vertically spaced from the first pair of fins, from the bottom of the central core and from one another, the second and third pairs of fins also having ends adapted to engage the void walls, but extending beyond the ends of the first pair of fins when uncompressed, the second and third pair of fins locking the sealing strip in place and providing secondary sealing against the entry of moisture and debris, inward and outward movements of the void walls causing the fins of each of the second and third pair of fins to rotate in opposite directions and to an equal extent, the rotation distorting the central core by compression and elongation thereof, the reinforcing web controlling the distortions on the central core by localizing the compression and elongation in a manner which produces, an equilibrium condition of localized opposing forces which lock the sealing strip in place.
