Described is a system for transmitting a flexural wave acting on one structure to another structure. In one example, a system includes a first structure having a first property and a first end and a second structure having a second property and a second end connected to the first end of the first structure. The first property is different from the second property and may be related to the material and/or geometric properties of the first and second structures. A mechanical resonator is connected to the first structure at a distance from the first end of about a quarter-wavelength of the frequency of a flexural wave acting on the first structure. The mechanical resonator matches a first mechanical impedance of the first structure to a second mechanical impedance of the second structure to allow high transmission of the flexural wave acting on the first structure to the second structure.

The invention concerns a building system for building a structure such as a dwelling, garage, shop, school, hall or the like comprising a number of interconnecting components whose assembly is dictated by their size and shape, the invention extends to components of said building system; a kit of parts thereof; and a method for building dwellings, garages, shops, schools, halls or the like.

Structural truss panels include first, second, third, and fourth horizontal elongated members and first and second vertical elongated members fastened to the first, second, third, and fourth horizontal elongated members. The first and fourth horizontal elongated members form respectively a top and a bottom of the structural truss panel. The first and second vertical elongated members forming respective sides of the structural truss panel. The structural truss panel further includes and an angled webbing fastened between the first and second vertical elongated members and the first and second horizontal elongated members thereby creating an integrated web truss within the structural truss panel. The structural truss panel includes first, second, and third brace members forming a V-braced truss panel.

A flat-mounted connector that enables industry standard hooks on horizontal rods to rest at such a height as to provide uniform appearance to the top of drape walls. The flat-mounted connector provides a connection that affixes to a flat wall or surface and an affixed coupler for the drape rods to be affixed to a vertical surface. The connector has an upper region with a similar outside dimension as the body of the coupler. In an internal portion of the coupler, at least one hollow well opens vertically with at least one lateral notch or opening formed in an upper region and designed to accept a terminal hook used on an end of a horizontally placed rod. An example connector includes two couplers affixed to the flat-mounted connection to accept additional terminal hooks.

A building system that includes a modular panel with side members, at least one of the side members having an associated coupling for hooked connection with a corresponding shaped fixture of an adjacent structure, the coupling and fixture being adapted to be held together by a locking device that, when engaged, acts to lock the structure and the side member together and, when disengaged, allows for play between the panel and structure in order to free the panel from the structure.

A universal hub adapter for a portable display frame assembly, the hub adapter being configured to mount to an outer surface of a display hub of the frame assembly. The universal hub adapter is configured to adapt the display hub of the frame assembly between the mounting of a first graphics system including a plurality of stretched fabric panels and a second graphics system including a channeled sub-frame for mounting a larger fabric panel. The universal hub adapter can include a faceplate having a substantially planar outer surface and a concave inner surface configured to mate with the convex outer surface of the display hub and a threaded post having a threaded portion, a securement plate, a button shaft, and a button head, the threaded portion configured to pass through an aperture of the faceplate and couple to the display hub, such that the securement plate abuts up against the faceplate thereby securing the faceplate to the display hub, the button shaft and button head configured to operably couple to one of a stretched fabric panel or a sub-frame assembly.

A method and an arrangement for supporting a first beam between a first support structure and a second support structure in a building frame structure. The method includes securing the first beam to a first console against movement along the first console by means of a mechanical joint between the first console and the first beam, and the first console at a location between the beam supporting surface of the first console and the mechanical joint with a deforming section having increased deformability compared to the deformability of the first console at the beam supporting surface by reduced material dimensions in said deforming section of the first console compared to the material dimensions of the first console at the beam supporting surface.

A fitting for coupling an open upper end of a hollow section column to a support via which a building unit is to be supported on the column. The fitting comprises a body portion configured to be received in the open upper end of the column and rim portions that extend laterally outwardly from an upper end of the body portion so as to engage edge sections of the column at its upper end when the body portion is received in the open upper end.

A structural assembly including a first structural member defining a first partial bore and including a first protrusion extending from a periphery of the first partial bore on a first side and a second protrusion extending from the periphery of the first partial bore on a second side, a second structural member defining a second partial bore and including a first protrusion extending from a periphery of the second partial bore on a first side and a second protrusion extending from the periphery of the second partial bore on a second side, wherein the second partial bore is aligned with the first partial bore to define a through-bore, a first engagement member engaged with the first protrusions and a second engagement member engaged with the second protrusions, wherein the first and second structural members are clamped between the first and second engagement members.
