The present invention provides a cross beam of a canopy, which addresses the problem that existing cross beams cannot simultaneously ensure convenience of assembly and guarantee stability in use. The present cross beam of a canopy comprises a plurality of hollow elongated beams, an inner side surface of each of the beams has at least one protruding and elongated protrusion along a length direction of the beams, each of the protrusions is provided with an mounting hole or a mounting groove penetrating along the length direction of the beams, at least one long rod is inserted into the mounting holes or the mounting grooves to connect all the beams in series, and two ends of the long rod protrude out of the beams and are detachably connected with a locking fastener respectively. The present invention ensures convenience of installation and guarantees the assembled cross beam has good stability.

A bracket assembly comprising a first bracket member associated with a first side of a structural element, a second bracket member associated with an opposed second side of the structural element, and wherein the first bracket member, the second bracket member and the structural element are fastened to one another using one or more fastening assemblies.

A connection node assembly for use in connecting an upper prefabricated building module to a lower module. Hollow vertical edge supports of the building modules have top and bottom connection parts. A connecting bolt can be passed through the top part of an upper vertical support in the upper building module and seated within the bottom part of that vertical support with the shank extending downward. The shank engages a threaded aperture in a connecting nut secured within the top part of a corresponding lower vertical support in the lower building module. Diaphragm plates sandwiched between the upper and lower vertical supports are used to tie horizontally placed modules together.

An H-beam joint structure for joining ends of H-beam steel materials adjacent to each other. The steel materials have a flange and a web. The joint structure includes: a transmission plate arranged parallel to a front surface of the web on at least one side of the web of the H-beam and the steel material, and welded to a back surface of the flange; and a coupling plate provided in close contact with the transmission plate to connect the H-beam and the steel material. A web of the H-beam, the web of the steel material and the transmission plate are bolted via the coupling plate. As a result, there is provided an H-beam joint structure which has a joining strength equivalent to a conventional joint structure for an H-beam, and also which can easily be constructed to have less parts and make front surfaces of the flanges flat.

The present invention relates to a building system and a method of making and assembling the building system. In particular, the present invention relates to a footing for a building structure, the footing comprises a plurality of precast concrete layers, each precast concrete layer comprising reinforcement bars and a plurality of apertures. The footing further comprises a base structure comprising a base plate and a plurality of alignment bars protruding from the base plate. The footing is configured such that when the plurality of precast concrete layers are positioned on top of one another, the plurality of alignment bars of the base structure extend through the respective apertures of each precast concrete layer. Furthermore, the present invention relates to a building structure having one or more building modules.

A friction plate for a timber joint between a first connection element of wood and a second connection element, with a plate-shaped carrier with a first carrier connection side for a surface connection to the first connection element and a second carrier connection side for a surface connection to the second connection element, and a roughening of at least one section of the first and/or second carrier connection side.

The present invention relates to a truss that allows the formation of an arc when connected with other trusses and that creates an optimal angle that generates a lower calculation effort in the structure.

The present invention also relates to an arched structure comprising a plurality of such trusses and to a shed comprising a plurality of arched structures.

A bracket includes a first wing, a second wing and a bridge that connects the first wing to the second wing. The first wing has a first inner surface and a first outer surface. The second wing has a second inner surface and a second outer surface. The bridge extends from the first inner surface to the second inner surface thereby coupling the first wing to the second wing such that the first inner surface is normal to a first direction, and the first inner surface is parallel to the second inner surface. The bridge includes a front edge and a rear edge. The front edge forms a recess that extends into the bridge towards the rear edge along a second direction that is perpendicular to the first direction, and the recess terminates within the bridge prior to reaching the rear edge.

Embodiments are directed to structural fuses and connection systems including the same. An example structural fuse includes at least one plate. The structural fuse includes a plurality of cutouts formed in the plate. The cutouts are configured to cause at least one first yield region of the plate to yield when a first load is applied to the plate. Optionally, the plurality of cutouts are configured to cause at least one second yield region to yield when a second load is applied to the plate. At least a portion of the first yield region is distinct from at least a portion of the second yield region and the first load is different than the second load.

Column-to-beam connection systems are disclosed herein, along with moment-resisting frames including the same and methods of repairing the same. An example column-to-beam connection system includes a shear component. The shear component includes abase plate that is connected to a column flange. The shear component also includes at least one vertical web extending from the base plate. The vertical web is connected to with a beam flange. The vertical web also defines one or more openings therein.
