ABSTRACT:
An industrial oven uses bi-directional expansion joints to accommodate lateral and longitudinal movement intersecting support beams of the oven's structural framework resulting from expansion of the support beams, the supported beams, and/or other oven components. The intersecting support beams may, for instance, comprise either roof purlins 1) and underlying roof trusses or 2) floor support members and underlying oven base support beams. Each bi-directional expansion joint includes a bracket permitting relative longitudinal and lateral movement between the support beams and the associated supported beams. The brackets preferably comprise L-shaped brackets each having 1) a vertical leg connected to the associated supported beam(s), 2) a horizontal leg connect to the associated support beam, and 3) expansion slots permitting lateral movement between the support beam and the bracket and longitudinal movement between the supported beam(s) and the bracket.
