A bracket mechanism is configured to facilitate connection of multiple rail elements to form an elongated element to span over a work space and/or to help support a continuous integral element spanning over a work space. The bracket mechanism can be configured to help ensure the rigidity of the elongated element positioned over the work space so that the elongated element does not sag or bow downwards as it extends over the work space.

Various embodiments regarding a lightweight wall body frame used for a clean room are described. According to an embodiment, a lightweight wall body frame may comprise: a frame body; a coupling portion comprising a coupling opening formed at the center portion of the frame body; first and second attachment surfaces formed on the outer surface of the frame body so as to attach a steel plate of the lightweight wall body; and first and second support portions formed inside the frame body and inclined so as to connect between the coupling portion and the first and second attachment surfaces and to support the same. Besides, various other embodiments are possible.

A connection between supporting and supported structural members, particularly between curtain walls and interior support structures, wherein the connector is a member having first potion and a second portion joined at a junction and the second portion is formed with a plurality of elongated slots and the connector rides in a track attached to the first structural member.

A support apparatus 100 is disclosed herein. In a described embodiment, the support apparatus 100 comprises a connector plate 202 having a connector primary plate 204 for mounting to a support structure 104, and opposing side leg portions 210,212 integrally formed with the connector primary plate 204 and projecting from the connector primary plate 204. Each of the opposing side leg portions 210,212 includes engaging members 222 for attaching the side leg portions 210,212 to respective side walls of an elongate support member 300. A load bearing connector is also disclosed, among other components.

A one-piece stud has a central longitudinal side; a first longitudinal side joined at a 90? angle to the first end of the central longitudinal side; and a second longitudinal side joined at a 90? angle to the second end of the central longitudinal side. The central side has a first and a second planar surface joined by an acute isosceles triangular channel midway between. The first longitudinal side is formed of a third and a fourth planar surface joined by an acute isosceles triangular channel midway between. The second longitudinal side has a fifth and a sixth planar surface joined by an acute isosceles triangular channel midway between. At an end opposite the 90? joint, the first longitudinal side and the second longitudinal side have free ends each forming a gapped right isosceles triangle. The longitudinal channels increase the axial capacity and the moment capacity of the stud.

The track is elongate such that it extends along a longitudinal axis. The track comprises an alignment feature located at a predetermined alignment position along the longitudinal axis of the track. The alignment feature is configured to secure a partition support member at the alignment position when the partition support member is received by the track. The alignment feature comprises one of a projection or recess configured to engage with the other of a projection or recess of the partition support member.

A wall cladding system includes a vertical support, a horizontal support, and a panel. The panel has a peripheral edge that abuts a first side surface of the vertical support and a top surface of the horizontal support. In various examples, a portion of the vertical support overlaps a portion of the horizontal support.

Systems for building customizable structures, without tools and without separate mechanical fasteners, as well as methods of use are described. Such structures may comprise at least two separate panels removably attached to a common panel-joiner. Such panels may be substantially planar and structural members. Such panel joiners may be substantially elongate members and structural members. Edges of the panels and complimentary-edges of the panel-joiners may be removably attached to each other by virtue of a plurality of clips running along a given edge and a complimentary plurality of clip-receivers running along the given complimentary-edge of the given panel-joiner. Such erected customizable structures, may then be used in firearm and tactical training. Such erected customizable structures may simulate various building structures, such as, but not limited to, rooms and/or hallways.

A containment system may include four different widths of panel assemblies, at least four different types of corner assemblies, various types of door assemblies, multiple types of three-way corners or T intersections, multiple types of exhaust panel assemblies, multiple types of wall seal assemblies, and other components that form a modular system capable of adapting to various configurations using a minimal number of fasteners, brackets, and/or clamps. Each panel assembly includes a lower assembly, an upper assembly slideably attached to the lower assembly, at least one adjustment mechanism that interfaces with both the lower assembly and the upper assembly, and a sealing member extending between the upper assembly and the lower assembly.
