Abstract

A watertight, integrated wall and roof expansion joint seal system includes an expansion joint seal for a structure. The seal includes a central portion having an underside and at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. The expansion joint seal includes a fold including a first fold portion and a second fold portion, wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of a the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure. The system further includes a joint closure.

Dependent claims

A watertight, integrated wall and roof expansion joint seal system comprising:

a) an expansion joint seal for a structure, the seal comprising:
a central portion having an underside and including a sidewall comprising members, the sidewall configured to define at least one central chamber disposed around a centerline;
a first flange portion extending outwardly from the centerline;
and
a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion;
wherein at least one of the first flange portion and the second flange portion is bifurcated into an upper flange portion and a lower flange portion, the upper flange portion extending further in length from the centerline than the lower flange portion, and the lower flange portion being substantially parallel to the upper flange portion, the thickness of each of the upper flange portion and the lower flange portion being planar and substantially the same as the thickness of the members of the sidewall;
a fold comprising a first fold portion and a second fold portion,
wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure;
and
b) a joint closure comprising a core and a layer of elastomer disposed on the core, the joint closure further comprising an end portion configured to match and integrate with the underside of the central portion to form the watertight, integrated wall and roof expansion joint system;
wherein movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.

and
a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion;
wherein at least one of the first flange portion and the second flange portion is bifurcated into an upper flange portion and a lower flange portion, the upper flange portion extending further in length from the centerline than the lower flange portion, and the lower flange portion being substantially parallel to the upper flange portion, the thickness of each of the upper flange portion and the lower flange portion being planar and substantially the same as the thickness of the members of the sidewall;
a fold comprising a first fold portion and a second fold portion,
wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure;
and
b) a watertight barrier located beneath the central portion and between the first substrate and the second substrate forming a watertight seal between the first substrate and the second substrate;
wherein movement of one or more of the first substrate and the second substrate causes a response in the central portion and in the watertight barrier to maintain the seal.
