In one embodiment employing trusses formed of folded sheet metal, a plurality of interconnected truss modules, each truss module including a plurality of truss members, forms a plurality of oppositely extending horizontal flanges that collectively present the top and bottom surfaces of a cantilevered canopy.

A shaft wall assembly system including triangular shaped steel studs with one or more layers of wall board secured to one side of the triangular shaped steel studs. The triangular steel studs preferably rest in a notched floor runner and a notched ceiling runner. The one or more layers of wall board are then directly attached to a flat side of the triangular stud with properly sized steel screws. This system will be useful as a shaft wall system or in locations where attachment of wall board to both sides of a wall system is not feasible.

A truss system comprises at least one truss element of mutually parallel tube bodies (11, 12) which are mutually connected in a ladder element (10) by a system of shores (15, 16). The tube bodies (11, 12) are provided at opposite outer ends with coupling means (13) for a force-transmitting coupling to a further truss element. Ladder elements (10) are connected releasably to each other by form-stiff coupling elements (30).

The present invention relates to a tie rod (13) capable of being fastened at two fastening points of a structure, said tie rod (13) having a first fastening end (15) comprising a first circular opening (17), and a second fastening end (16) comprising a second circular opening (18). According to the invention, the tie rod (13) has a washer (19) which is provided with an off-centre orifice (21), said washer (19) being received concentrically in the second circular opening (18) and being movable in rotation in said second circular opening (18) so as to modify the position of the off-centre orifice (21) in order to vary an interaxial fastening distance between said off-centre orifice (21) and the first circular opening (17).

The invention concerns a truss structure including a plurality of longitudinal members extending parallel to one another in a main extension direction and crossmembers (9) distributed in the main extension direction to connect the longitudinal members mechanically two-by-two, forming a plurality of polygons (11) each contained in a plane perpendicular to the main extension direction.

According to the invention, each crossmember (9) connecting two longitudinal members includes a first half-crossmember (9a) with a first end connected to one of the two longitudinal members so as to be able to pivot about a first axis (X1-X′1) and a second half-crossmember (9b) a first end of which is connected to the other of the two longitudinal members so as to be able to pivot about a second axis (X2-X′2). The two half-crossmembers are connected to one another by an articulation hinge (13) allowing relative rotation of the two half-crossmembers (9a, 9b) about a third axis (X3-X′3). The first, second and third axes are parallel to one another and orthogonal to the main extension direction, allowing the truss structure and each crossmember (9) to pass from a deployed position to a folded position in which the first and the second half-crossmembers (9a, 9b) of each crossmember (9) extend substantially parallel one alongside the other in said main extension direction.

A tower section is for a truss tower. The tower section has three or more elongated corner beams arranged in parallel and spaced apart, and a plurality of transverse beams connected perpendicular to adjacent corner beams, thereby forming respective three or more sides. The transverse beams are distributed along the sides so that the transverse beams of one of the side are arranged offset to the transverse beams of the other sides.

An extruded profile defining a normal section surface, a horizontal loading direction along the normal section surface and a vertical loading direction along the normal section surface perpendicular to the horizontal loading direction The profile includes a core arranged in a central position at the intersection of the directions, a plurality of arms each including a radial segment radially connected to the core and a tangential segment perpendicularly connected to the radial segment The radial segments of the adjacent arms are perpendicular to each other and each oriented 45° to the horizontal load direction and/or the vertical load direction, and the tangential segments of the adjacent arms are configured to simultaneously support the same load along the horizontal load direction and/or the vertical load direction.
