Aspects of the present disclosure relate to modular wall systems and methods of installing modular wall systems in hygienic environments. In one aspect, gap cover apparatus are disclosed. In one aspect, backplate arrangements are disclosed. In one aspect, non-progressive installation methods are disclosed. The modular wall systems can eliminate protruding ledges while maintaining structural integrity and hygienic properties.

A fire-resistant partition wall includes wall studs and first and second walls each including gypsum boards with vertical and lateral joints. The wall studs are on the back side of the vertical joints. A joint base member is provided at the lateral joints. The gypsum boards, the joint base member, and the wall studs are not screwed with a common screw, and (a) the gypsum boards are screwed to only the wall studs and are not screwed to the joint base member, and the joint base member is fixed to the lateral joint position by being inserted between the gypsum boards and the wall studs, or (b) the gypsum boards are screwed to the wall studs and to the joint base member with different screws, and the joint base member is fixed to the lateral joint position by being inserted between the gypsum boards and the wall studs.

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.

A wall stud member comprising an inner component and an outer component. The inner and outer components are coupled together. In some configurations, the wall stud member forms a web with an outer flange and an inner flange. The wall stud member may be positioned as a part of a wall construction.

Aspects of the present invention relate to a wall assembly for mounting a wall in a residential or commercial building space. The wall assembly has a wall body having an upper region configured to be laterally supported at one or more upper surfaces thereof to maintain the wall body in a substantially upright position, and a lower region configured to be laterally supported at one or more lower surfaces thereof to maintain the wall body in a substantially upright position. The wall assembly further has at least one lateral support comprising an engagement portion configured to engage the one or more upper surfaces of the upper region or one or more lower surfaces of the lower region of the wall body. The wall body has a unitary body having a molded material.

In a facade assembly (14) for a building (10) with at least one facade element (16), which can be fastened to a wall or an inter-story ceiling (12) of the building (10), and with at least one fire-protection element (18), which can be mounted between the facade element (16) and the wall or the inter-story ceiling (12), the fire-protection element (18) has at least one fire-protection course (32) of an intumescent material.

Furthermore, a method for mounting such a facade assembly is provided, as is a building structure using the facade assembly.

A fire-blocking gasket includes a profile having a plurality of legs and defines an interior space. The interior space including a fire-blocking material and/or an intumescent material for providing fire, smoke and/or sound protection across a deflection gap in a building joint. The gasket can be installed within the building joint by direct attachment with a track member within the deflection gap.

An elongate component for placement in a wall gap and a wall incorporating such a component. The component includes a wall-face leg configured to extend along a face of a wallboard and a wall-end leg configured to extend along an end of the wallboard. The wall-end leg is oriented perpendicular to the wall-face leg. The component further includes a flexible gap portion configured to be positioned within and extend along the wall gap. The gap portion is located on an opposite side of the wall-end leg relative to the wall-face leg. A blocking element is located in a space defined by the wall-end leg and the gap portion. The blocking element is configured to block fire and/or sound within the wall gap. At least a portion of the flexible gap portion is located on an exterior side of the blocking element.

An insulating strip is disclosed. The insulating strip includes a support layer and an insulating material strip secured to the support layer. The insulating material strip includes a first insulating material strip part and a second insulating material strip part where the first insulating material strip part and the second insulating material strip part are spaced apart from each other.
