A truss structure for a scene for shows, wherein the truss structure is adapted for supporting equipment for scenes or stages. The truss structure consists to an elongated structure having four sides; and reinforcement members made of a single component, preferably a plate, that are secured to the sides of the elongated structure. The reinforcement members are covering a substantial portion of the sides of the truss structure, while comprising recesses distributed along the longitudinal edges of the reinforcement member for mounting a piece of equipment to the truss structure. The reinforcement members are enhancing rigidity of the truss structure and resistance of the truss structure to torsion or shearing forces.

MULTI-LAYER FLOOR SYSTEM COMPRISING A LIGHTWEIGHT TILE
A lightweight multi-layer tile of a floor system for scenes or stages easy to install and easy to flip to show up any of its two faces is described. The multi-layer tile has a top surface and a bottom surface that can both be shown. The multi-layer tile has a frame defining a rigid structure; a core low-density component inserted in the frame such that the frame surrounds it; and dense plywood panels affixed to opposed walls of the core component. The panels extend beyond the core component over a section of the frame, with a surrounding lip of the frame surrounding and protecting the edges of the panels. The panels provide the reversible surfaces of the multi-layer tile, allowing to show one or the other surface by flipping the tile upside down.
The elongated double-fold foldable structural truss has a quadrilateral framework extending along a longitudinal direction. It includes four chord beam units disposed parallel to one another. Each chord beam unit includes two spaced-apart and juxtaposed beams running parallel to one another. The beams define between them a first open channel that is opened on one of the inner sides of the chord beam unit. The structural truss further includes four web units having brace members. The brace members of at least two of the web units are telescopic. The telescopic brace members are all in their extended position when the structural truss is in its unfolded position and being all in their retracted position when the structural truss is in its folded position. The foldable structural truss is very compact in its folded position.

The elongated double-fold foldable structural truss (100) has a quadrilateral framework (102) extending along a longitudinal direction (104). It includes four chord beam units (110) disposed parallel to one another. Each chord beam unit (110) includes two spaced-apart and juxtaposed beams (112) running parallel to one another. The beams (112) define between them a first open channel (134) that is opened on one of the inner sides of the chord beam unit (110). The structural truss (100) further includes four web units (120) having brace members (122). The brace members (122) of at least two of the web units (120) are telescopic. The telescopic brace members (122) are all in their extended position when the structural truss (100) is in its unfolded position and being all in their retracted position when the structural truss (100) is in its folded position. The foldable structural truss 100 is very compact in its folded position.
The knockdown louvered wall system (100) a plurality of spaced-apart blade panels (120) disposed in superposition across an open space (112) between side frames (102). Each blade panel (120) includes a main panel member (122), two traction bars (130), each extending along a corresponding one of minor side edges (126) of the blade panel (120), two tie members (140), each extending along a corresponding one of major side edges (124) of the blade panel (120), and a plurality of blade connector assemblies (170) disposed between the blade panels (120) and the vertical rails (114). Each blade connector assembly (170) has an outer end slidingly connected to corresponding ones of the vertical rails (114) and an inner end removably attached to a corresponding one of the traction bars (130).

The structural truss includes a connector plate member welded to the framework between two corresponding longitudinal tubes. The connector plate member is made of a monolithic piece. It includes a corner beam section protruding from the rear side of the connector plate member and a main plate section extending perpendicularly inwards on a side of the corner beam section. The main plate section and the corner beam section define together a planar outer abutment plate surface. The connector plate member also includes a lip projecting at right angle from the main plate section on the rear side of the connector plate member. The lip extends substantially parallel to the corner beam section.
