Abstract: A floor expansion joint (100) for placement between two flooring parts comprises a first elongated bracket (110) defining a first elongated bracket longitudinal axis and a second elongated bracket (120) defining a second elongated bracket longitudinal axis. The second elongated bracket (120) is nested within the first elongated bracket (110) such that the first elongated bracket longitudinal axis and the second elongated bracket longitudinal axis are substantially parallel. The first elongated bracket (110) and the second elongated bracket (120) are reversibly translatable relative to each other along an axis substantially perpendicular to the first and second elongated bracket longitudinal axes, and the first elongated bracket (110) and the second elongated bracket (120) are reversibly translatable relative to each other between an expanded configuration and a contracted configuration. The floor expansion joint is configured such that the first elongated bracket (110) and the second elongated bracket (120) are resiliently biased from the contracted configuration to the expanded configuration. A floor expansion joint kit comprises a first elongated bracket (110) defining a first elongated bracket longitudinal axis and a second elongated bracket (120) defining a second elongated bracket longitudinal axis. The second elongated bracket (120) is configured to be nested within the first elongated bracket (110) such that the first elongated bracket longitudinal axis and the second elongated bracket longitudinal axis are substantially parallel. In use, the first elongated bracket (110) and the second elongated bracket are configured to be reversibly translatable relative to each other along an axis substantially perpendicular to the first and second elongated bracket longitudinal axes, and the first elongated bracket (110) and the second elongated bracket (120) are reversibly translatable relative to each other between an expanded configuration and a contracted configuration. In use, the floor expansion joint is configured such that the first elongated bracket (110) and the second elongated bracket (120) are resiliently biased from the contracted configuration to the expanded configuration. A method of installing a floor expansion joint (100) between two flooring parts comprises providing a first elongated bracket (110) which defines a first elongated bracket longitudinal axis and providing a second elongated bracket (120) which defines a second elongated bracket longitudinal axis. The method further comprises forming the floor expansion joint by nesting the second elongated bracket (120) within the first elongated bracket (110) such that the first elongated bracket longitudinal axis and the second elongated bracket longitudinal axis are substantially parallel, wherein the first elongated bracket (110) and the second elongated bracket (120) are reversibly translatable relative to each other along an axis substantially perpendicular to the first and second elongated bracket longitudinal axes, the first elongated bracket (110) and the second elongated bracket (120) being reversibly translatable relative to each other between an expanded configuration and a contracted configuration, and wherein the floor expansion joint is configured such that the first elongated bracket (110) and the second elongated bracket (120) are resiliently biased from the contracted configuration to the expanded configuration. The method further comprises installing the floor expansion joint in a gap between two flooring parts such that the first elongated bracket (110) abuts against one of the two flooring parts and the second elongated bracket (120) abuts against the other of the two flooring parts.
