A timber beam hanger connects a first member, e.g. a horizontal or inclined beam, to a second member, e.g. a horizontal or inclined beam disposed perpendicularly or obliquely to the first beam, or a vertical post or wall. The beam hanger comprises a generally vertical web, an upper flange extending from an upper edge of the web, a seat extending from a lower edge of the web and a connector. The upper flange and seat are usually rectangular and disposed parallel to each other and normally to the web. The upper flange is secured to an upper face of the first member, and the connector cooperates with the upper flange and is secured to the second member. A joint face of the first member has a generally vertical slit intersecting the upper face and receiving the web therein. The joint face has a generally horizontal slit intersected by the vertical slit at a position remote from the upper face and receiving the seat therein. Weight of the beam is carried on the seat and a variety of connectors connect the beam hanger to the second beam or post. When installed, most of the beam hanger is enclosed in the slits of the first member and thus is essentially invisible when viewed from beneath or sideways of the beam. |
