Abstract: A fabric panel attaching system and methods of assembly and use are presented for attaching fabric panels to structural elements, such as building frames. In various embodiments, the fabric panel attachment system includes a keder rail fastened to support bar, which is attached to a structural profile, such as a building frame member. In some embodiments, the keder rail is fastened to a support bar with bolt and nut. One or more fabric panels are installed within channels of the keder rail. An alignment element may be used with a fastener to assist in aligning abutting sections of keder rail. In various embodiments, the fabric panel attachment system is secured to flat or curvilinear faces of the structural elements. In some embodiments, the fabric panel attachment system may secure directly to the structural element and not a support bar.

Abstract: A material handling tower includes a plurality of vertical column trees forming corners of the tower. Each of the plurality of column trees forms a moment connection including a pair of stub connectors. The stub connectors are perpendicular and extend in a direction of an adjacent column tree. Each stub connector has a proximal end welded to the column tree and a distal end having a connecting plate. The tower has at least one interior platform connecting to the plurality of column trees. Each of the at least one interior platforms has a plurality of outer girders with the outer girders connected to the stub connectors of the moment connections. Each girder has a connecting plate at each of its ends and each of the moment connections is completed by connecting the connecting plate of the stub connectors to the connecting plate of the girder.
