ABSTRACT:
The disclosure concerns a multipurpose structural unit for fastening parts of buildings, or the like, together. The unit comprises a longitudinally elongaged bar, which may be either solid or hollow and which may be comprised of various different materials. The bar has two opposite transverse sides and two opposite end sides which joint the transverse sides. At least one longitudinal groove is defined in each transverse side of the structural unit, and a longitudinal groove may also be defined in each end side of the structural unit. The surfaces between the edge of the groove in the transverse side and the end side of the structural unit slant obliquely inwardly toward the center of the structural unit, whereby the structural unit has a generally octagon shaped exterior profile or cross-section. The cross-section shapes of the longitudinal grooves are disclosed. Various possible inserts and configurations for using the structural unit in combination with other structural elements and parts are disclosed, principally through insertion of the margins of the various structural elements and parts into the grooves in the structural unit.
