A seismic axial dampener device is constructed of a multitude of composite or metallic conical compression discs and an exo-structure capable of dampening both tension and compression cycles of a building structure due to a seismic, explosion, or wind event. The dampener reacts and dampens the loading in both tension and compression along the axis of the cross brace in linear-elastic bending, creating internal hoop stress, and not through shear of the dampener device.

A column (1) for supporting a covering, comprising a core profiled section (2) having a plurality of fitting grooves in its periphery and a plurality of insertion profiled sections (3, 4, 5) which are each interchangeably fittable into each fitting groove, in such a way that the column (1) has a substantially rectangular cross section, each inserted insertion profiled section (3, 4, 5) in each fitting groove forms a corner (10) of the rectangular cross section of the column (1) and each side wall of the column (1) between the insertion profiled sections (3, 4, 5) is formed by the core profiled section (2). The present invention also relates to a screen construction comprising such a column (1).

A modular beam structure consisting of one or more collapsible, lockable and interconnectable support structure modules, and any transition module to change longitudinal direction of the structure. In addition, it is possible to attach onto one or more support structure modules a collapsible platform and/or wall or fence. The structure is at an upstream end or start end attachable, via a module end element, onto an attachment device, e.g. a wall or attachment block, via a support frame which is fixedly attached to the attachment device.

A platform erected by adding an other platform portion to an existing platform portion, as illustrated in FIGS. 20 to 23, by holding a first other truss adjacent decking of the existing portion, connecting ends of sides of the first other truss and a first existing truss with a first pin, swinging the first other truss about the first pin, and connecting ends of other sides of the first other truss and first existing truss with a second pin. In order to similarly connect a second other truss to a second existing truss, the first pin is removed and the first other truss is swung out of the way. After the second other truss is connected to the second existing truss, the first other truss is swung back into position and the first pin re-inserted. Decking is applied to the first and second other trusses.

The present disclosure relates to reinforcement devices, systems and methods for use in constructing new structures, including post frame structures. Specifically, the present disclosure relates to reinforcement devices, systems and methods for replacing traditional wood and/or precast concrete columns utilized in building a new construction foundation, with a height adjustable foundation column assembly constructed from a corrosion resistant material. The present disclosure also relates to reinforcement devices, systems and methods useful for reinforcing existing post frame structures, particularly those with framing elements requiring repair.

Reinforcing bars include load transfer connectors. A link plate includes openings that mate with the load transfer connectors to overlie the splice between reinforcing bars being spliced. A cover plate may be fastened over the link plate.

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.

A wind turbine tower wall having an orifice for accessing the interior of the tower, and an outer surface defined by generatrices; and a reinforcement frame joined to the tower in the orifice zone, and comprising least two parts joined one to each other. Each part has a mid-plane that is parallel to at least one generatrix, the mid-planes of at least one pair of adjacent parts forming an angle other than 180 therebetween. It enables the obtention of a frame more conformed to the curvature of the tower, combining savings in the material of said frame, greater optimization of the resistance of the tower and reduced stress concentration.

Flange-to-flange connectors and construction methods using such connectors are disclosed. The connector may include a first and second anchored plates secured to a first and second sets of anchoring bars. The connector may also include a first and second alignment plates configured to mate with the first and second anchored plates. The connector may further include at least one shim configured to be positioned between the first and second anchored plates. A bolt may be configured to secure the first and second alignment plates with the first and second anchored plates, respectively, and when the bolt is tightened, the bolt pulls the first and second alignment plates and the first and second anchored plates together to form a rigid connection, which may eliminate the need to form and cure concrete at job sites, allowing the time, cost, and construction complexity to be reduced significantly compared to conventional connection systems.
