Modular building

Abstract

A roof for a modular building comprises a ridge beam extending along a ridge beam axis. The ridge beam includes, when viewed in cross section, a load bearing central section, and first and second roof panel connectors on opposed first and second sides of the central section. The roof further comprises at least a first and a second roof panel extending transversely to the ridge beam axis and downwardly and outwardly from the ridge beam. Each roof panel comprises an inner end portion and an outer end portion. The inner end portion of the first roof panel is engaged by the first roof panel connector, and the inner end portion of the second roof panel is engaged by the second roof panel connector. The roof further comprises a first tie for the outer end portion of the first roof panel, and a second tie for the outer end portion of the second roof panel. Each tie extends parallel to the ridge beam axis and comprises a top portion and a bottom portion. The top portion comprises a roof panel outer end channel in which the outer end of one of the first roof panel and second roof panel is received, and the bottom portion comprises a wall channel in which a wall of the modular building is received.
