The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

The present invention provides for a metal stud for use in sound attenuating wall systems utilizing high density, abuse resistant wallboard, the metal stud having specific steel chemical and mechanical properties to result in increased sound attenuation properties while maintaining the load carrying capacity and screw performance providing improved economics. The metal stud is a generally C shaped metal stud constructed of 0.0180 steel having at least 57 ksi strength having two parallel spaced apart flanges joined along the length of one edge by a central web and being provided with an in-turned double thickness hemmed ledge along the length of the second edge, the flanges having a width of greater than 1 inches between the one edge and the second edge, each of the flanges being provided with a reinforcing rib centrally located in the flange extending the length of the flange. The central web has a main central section bordered by channel shaped ribs extending longitudinally of the stud outwardly of the central web, the edges connected to the edges of the flange.

A frame design and a sheathing design for a design model may be produced by the systems and methods described herein. A processor in communication with a database may receive a design model comprising building specifications. The processor may define a panel in the design model and generate the frame design and the sheathing design for the panel.

A 3D-printed integrated panel, assembly, or other building element configured to form part of an overall building can include 3D-printed panels, connectors, and load transfer components. 3D-printed panels can be integrally formed by 3D printing technology using a photocurable composite material. A 3D-printed panel can include an outer frame shell defining a geometric shape having interior and exterior outer surfaces, side edges therebetween, and an infill structure therewithin, the infill structure forming internal cavities within the outer frame shell. Connectors can couple 3D-printed panels to each other and/or to separate building components of the overall building. Load transfer components can be coupled to and transfer loads across 3D-printed panels. Waterproofing elements can be coupled to 3D-printed panels, and thermal insulation material can be disposed within the internal cavities. The panel, assembly, or other building element can comply with building construction standards. Panels or assemblies can include wall panels.

A composite wall assembly has an auxiliary wall and an inner wall. The auxiliary wall has a hollow space and a first supporting pillar having multiple first through holes. The inner wall is attached to the auxiliary wall and forms a depositing space. The inner wall has a first wall member, a second wall member, and a second supporting pillar having multiple second through holes. The depositing space is formed between the first wall member and the second wall member. The auxiliary wall provides a cushion effect and is not damaged easily in the earthquake for protecting the pipelines in the hollow space. The interior ambient temperature of the building is lowered by the hollow space of the auxiliary wall.

An aircraft storage bin that includes an upper housing and a bucket that cooperate to define a bin interior. The bucket is movable with respect to the upper housing between open and closed positions and includes a bottom and right and left side panels. The bottom includes lower and upper surfaces and right and left outer edges. The right and left side panels each include a first section having a first transverse width, a second section having a second transverse width, and a transition section that is located between the first and second sections. The second transverse width is less than the first transverse width. At least a portion of the second section of each of the side panels is received in a slot defined in the upper surface of the bottom of the bucket, such that the right and left side panels extend upwardly from the bottom.

A construction system includes a metallic stud definable in terms of an X, Y, Z coordinate system. The system includes a Z-axis elongate substantially rectangular integral web within a YZ plane, the web having a stability elements along a Z axis line of dependency with a first edge of the web, the elements defining an L-shaped element having a foot occupying a YZ plane substantially parallel to the web. The system also includes a second and opposite Z-axis edge of the web defining a series of trapezoidal cut-outs having openings at a minor base of each trapezoidal cut-out.
