An architectural fixture assembly including a generally U-shaped first beam having a bottom side, a first side, a second side, and a first end. Interior surfaces of the first, second, and bottom sides of the first beam define an interior portion. A connector includes a plate, and a connection key extending away from the plate. The interior surfaces of the first and second sides each include a generally V-shaped alignment notch disposed generally adjacent to the first end of the beam. The connection key includes a pair of generally V-shaped sides disposed on opposite sides of the connection key, and each generally V-shaped side is configured to slidably engage one of the generally V-shaped alignment notches.

A system for air decontamination in a three-dimensional space described herein includes an air inlet for drawing in air, an air outlet for administering filtered air, and a filter device for filtering air prior to administration through the air outlet, the system is configured to draw air in a substantially vertical laminar flow from a ground of the space to the air inlet. A filter device for filtering ultrafine particles from a gas described herein includes a first filter medium for absorbing polar liquids but not ultrafine particles; in fluid communication with a second filter medium for absorbing ultrafine particles; and a gas outlet, the first filter medium is configured to allow vaporization of the absorbed polar liquids; the device is configured to guide the gas from the first to the second filter medium and through the second filter medium; and the second filter medium forms the gas outlet.

An architectural fixture assembly includes a first beam and a second beam which are configured to be coupled together. The first beam includes a bottom side and first and second sides extending from the bottom side. The first and second sides of the first beam include notches extending upwardly from a bottom end of the first beam. The second beam includes a bottom side and first and second sides extending from the bottom side. The first and second sides of the second include notches extending downwardly from a top end of the second beam. The first and second beams may be coupled together by engagement of the notches of the first beam with the notches of the second beam.

A pre-fabricated universal operating room ceiling system including red iron steel support frames and a track assembly immediately above the ceiling in the interstitial space of the operating room for supporting medical equipment including medical gas lines and electrical and data cabling and heating, ventilation and cooling trunk lines and ducts for reducing interference with such systems when installing or moving operating room equipment.

A canvas hanger profile for making a stretched ceiling in a room to be conditioned, the hanger profile comprising at least two wings connected together by a connecting lining, one of the wings being arranged to allow the fastening of the hanger profile on a wall of the room to be conditioned, a second wing, which constitutes a canvas hanger wing, being provided with a blocking end of a canvas hook, wherein the connecting lining and the hanger wing are arranged to define together an unclosed air passage slot through the profile and are delimited by the blocking end of the hanger wing hook, the profile having at least one through opening arranged to allow air to pass through said profile from or towards the slot.

The present disclosure relates generally to suspension ceiling grids, for example, suitable for holding a suspension ceiling composed of ceiling tiles. The present disclosure relates more particularly to a vented suspension ceiling support beam including an elongate body extending in a longitudinal direction. The body includes a vertical web, and opposing first and second flanges protruding laterally from the vertical web. A vent is formed through the first flange.
