Abstract
An expansion joint seal includes a central portion having 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. When installed on the structure, the first flange portion is attachable to a first substrate of the structure and the second flange portion is attachable to a second substrate of the structure such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure. Movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.
Claims9
An expansion joint seal for a structure, the seal comprising:
- a central portion 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 lower flange portion being substantially parallel to the upper flange portion, and the upper flange portion extending further in length from the centerline than the lower 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;
- wherein when installed on the structure the first flange portion is attachable to a first substrate of the structure and the second flange portion is attachable to a second substrate of the structure 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
- 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.
