A support wall frame system includes an end track, and a metal frame member received within the end track. The metal frame member includes a plurality of ribs and a plurality of stiffeners spaced therefrom, respectively. The plurality of ribs are statically affixed to the end track, and the plurality of stiffeners are abutted against the end track. An inwardly directed V-shaped stiffener is located along base while each side wall has an inwardly directed rib. Each end of the stud is received within the end track such that the end track has a base with upwardly directed side walls, these side walls each having an inwardly directed detent. The stud is friction held between the end track's side walls and each detent is received within a respective one of the ribs to lock the stud. Fasteners pass through each -detent-rib pair.

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.

A partition, mounted on a mounting surface, comprises a plurality of elongate upright members, a first board and a second board. The first board is mounted on one side of a pair of the elongate upright members that are adjacent to each other, and the second board is mounted on the other side of the same pair of adjacent elongate upright members, so as to provide a cavity between the pair of elongate upright members and the first and second boards. The partition further comprises a spacer that is located within the cavity, the maximum dimension of the spacer in the through-thickness direction of the partition being at least 90% of the separation of the two boards. The spacer may help to reduce the extent of inward bowing of the boards between adjacent elongate upright members, so that, for example, the upright members may be spaced further apart.

A fixing device for mounting wall elements for constructing a wall, includes: a support profile, A securing element which is designed to extend between the wall elements and can be twisted relative to the support profile between a first position in which an engagement element of the securing element remains separate from the support profile, and a second position in which the engagement element engages on the support profile for fixing and secures the wall elements; and a closing profile which in the second position is attachable to the securing element and comprises a blocking element for preventing the securing element from twisting back.

An adjustable truss structure is provided and includes a truss member, a first channel having a first slot, the first channel being attached to the truss member, a rail having a second slot, and an anchor attached to the rail, the anchor having a member rotatable to a first position where the member is insertable into the first slot and rotatable to a second position to engage with a surface of the first channel, enabling the rail to be selectively moved relative to the first channel and locked into a selected fixed position relative to the first channel. A support member having a second channel with a U-shaped cross-section, the second channel being hooked into the second slot and being slidable in the second slot.

Techniques for and examples of a partition wall structure of a building are described, including a first shell formed as a first wythe including a first group of stacked elongated beads of extruded building material, a second shell spaced apart from the first shell and formed as a second wythe that has a second group of stacked elongated beads of extruded building material, and at least one structural support having a first portion embedded in the first wythe, and a second portion embedded in the second wythe.

It is described herein an adjustable rigid clip assembly comprising an anchor plate joined with a connector plate and a slide plate. The anchor plate is joined with the connector plate at a juncture having a juncture angle between the anchor plate and the connector plate in a range of between 0 and less than 180. The connector plate comprises at least one connector plate slot and at least one connector plate lock. The slide plate may comprise at least one slide plate lock. The at least one slide plate lock may be engaged with the at least one connector plate lock. The slide plate may further comprise at least one slide plate tab passing from the slide plate through the at least one connector plate slot.

A plenum housing includes a plurality of construction panels and a plurality of compression seal groove connectors secured between the plurality of construction panels. Each of the plurality of compression seal groove connectors includes a recess having at least one interior surface with at least one compression seal groove.

A multi-position mounting system is provided for securing a wall panel or hanging to a vertical wall, the wall panel or hanging having a front surface facing away from the wall, a back surface opposite the front, and one or more side surfaces connecting the front and back surfaces. In one embodiment, the multi-position mounting system includes a notch disposed in the back surface of the wall panel, the notch having at least three edges, each edge defining a separate sidewall surface. The notch is configured to secure to a bracket affixed to the vertical wall, the bracket configured to separately mate with each sidewall surface of the notch, wherein mating the bracket with an adjacent sidewall surface of the notch slightly rotates the wall panel with respect to the vertical wall.
