Abstract
An expansion joint seal for a structure 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.
Claims12
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 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;
- 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;
- 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
- wherein at least one of the first flange portion and the second flange portion is comprised of a flexible material such that the at least one of the first flange portion and the second flange portion is affixed to the structure at an angle or an elevation that differs from the central portion;
- and the seal is configured to transition between two substantially perpendicular substrates while maintaining continuity of seal;
- the expansion joint seal further comprising a bracket disposed between the upper flange portion and the lower flange portion to facilitate mounting of the expansion joint seal to the structure, the bracket comprising a curved anchor bar receiving a fastener therethrough.

A watertight expansion roofjoint seal for a roof, the roofjoint 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 the upper flange portion and the 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;
- wherein when the roofjoint seal is installed on the roof the first flange portion is attachable to a first substrate of the roof and the second flange portion is attachable to a second substrate of the roof such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate, at least one of an upper flange portion and a lower flange portion interlaying with one or more layers of roofing materials to provide a watertight seal with the roofing materials;
- 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
- wherein at least one of the first flange portion and the second flange portion is comprised of a flexible material such that the at least one of the first flange portion and the second flange portion is affixed to the structure at an angle or an elevation that differs from the central portion;
- and the seal is configured to transition between two substantially perpendicular substrates while maintaining continuity of seal;
- the watertight expansion roofjoint seal further comprising a bracket disposed between the upper flange portion and the lower flange portion to facilitate mounting of the seal to the structure, the bracket comprising a curved anchor bar receiving a fastener therethrough.
