ABSTRACT:
A bracket (90) fixedly supports a structural member (120) with respect to an aperture (128). The bracket (90) has a semicircular cross section body (100) with one end portion (94) for placement on the structural member. A second end portion (96) extends into aperture (128). The bracket body (100) has a plurality of longitudinally extending corrugations (92) along the body. A wedge shaped driving member (98) extends outward from the body (100) and extends between the first and second body portions (94) and (96). A clamp (130) and/or screws (188) fasten the first bracket body portion (94) to the structural member (120) or (180). In use, the bracket (90) is driven into the aperture (128) by striking the driving member (98). The driving member (98) and the corrugations (92) coact with the aperture (128) to provide a camming action, which expands the bracket body end (96) in at least one dimension to hold the bracket (90) tightly in the aperture (128). As a result of this expansion, a single bracket (90) will provide sufficient support for the post (120) in most applications.
