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 fire-rated component for a fire-rated joint, such as a head-of-wall assembly, includes an elongate body having at least a first layer, which can be in the form of a polymer profile. A second layer can be or include a foil lining and a third layer can be or include an intumescent material. The elongate body, such as the first layer, defines an air gap. The foil lining and/or the intumescent material can be positioned within the air gap. A planar lower portion of the first layer of the elongate body is positioned between a header track and a wallboard in the fire-rated joint. A non-planar upper portion of the first layer of the elongate body is positioned at least partially within a deflection gap of the wall assembly and sealingly engages the ceiling.

The present invention discloses an integrated steel concrete building and its construction method. The building comprises a plurality of prefabricated room modules of steel, each including at least one column having a structure of hollow steel tube, which has an inner chamber inserted with penetrating rebars and poured with concrete. The penetrating rebars extend upwardly out of the column of the prefabricated room module into an inner chamber of a column of a prefabricated room module of an upper floor.

Fireworthy sealants may have a variety of compositions and be made by a variety of techniques. In certain implementations, a fireworthy sealant may include a body comprised of a cured, tacky, soft, deformable non-adhesive gel. The gel body may have an upper surface, a lower surface, and a perimeter, wherein the upper and lower surfaces of the gel body, in an uncompressed state, define a body thickness. The sealant may, in an uncompressed state, be dimensioned to fit in a first opening between a wall and an aircraft component surface and deformable when under compression to fit in a second opening, smaller than the first opening. The sealant may be flame retardant and produce low smoke density and low smoke toxicity.

A multi-level parking garage constructed to be in close proximity to an adjacent building includes two or more levels above ground. Each of the two or more levels has a floor and a ceiling. The multi-level parking garage includes a load-bearing support structure for supporting the two or more levels and a plurality of fire-rated, non-load bearing exterior wall panels. Each of the exterior wall panels are independently and removably mounted to the support structure around at least a portion of a periphery of each of the two or more levels such that the plurality of exterior wall panels extend from the floor of each of the two or more levels to the ceiling of each of the two or more levels.

The melting-fuse may be a non-stable container that contains compressed or vacuumed mineral wool, such as stone wool, that is attached to the fixation details between building components that must be air-permeable that must then provide sufficient fire resistance. The application includes melting-fuses. The fuse works in two parts, first it holds the compressed or vacuumed mineral wool in the desired location, without this prematurely expanding and thus interrupting the necessary air flow. The second form of the fuse is designed for the fact that this melts first in the event of fire, after which the compressed or vacuumed mineral wool expands and seals the cavity.

Through the melting of the fuse and the subsequent sealing of the detail/opening where the application is installed, the further spread of the fire through the air flow is prevented.

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.

An expansion joint seal system which includes intumescent to protect uncoated edges of substrates. A fire rated compressed expansion joint sealant is provided having an intumescent proximate, but below the water-resistant top of the fire-retardant foam, so that when exposed to fire, the intumescent expands to protect the exposed vertical surface of the adjacent concrete substrate. The end of the concrete is therefore protected in a manner which does not require joint overlap between the horizontal fire resistant coating and the compressible sealant.

A cap for a tubular sleeve having a cylindrical wall extending along a longitudinal axis for forming a passage through a concrete structure. The sleeve has radially extending ridges separated into segments with a channel parallel to the longitudinal axis. The channel has a circumferential width W. The ridges spaced apart a distance Z along the longitudinal axis. The sleeve having an inner diameter D. The cap has a cap element and a positioning tab. The cap element has a circular outer periphery with a flat top surface and a flange having a bottom end, and the tab extends inwardly from the bottom end and has a bottom surface that is orthogonal to the longitudinal axis. The tab has an inner surface that is inclined at an acute angle to the bottom surface. The tab has a width smaller than W and an axial length smaller than Z.
