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 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.

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 perimeter frame used in a construction of floors or roofs of buildings, including three superior radial sub-frames, three inferior radial sub-frames, and six non-perpendicularly interconnecting top hat sub-frames, wherein each superior radial sub-frame is located between a pair of inferior radial sub-frames such that there is a 60° angle between the first and second longitudinal axes of any two adjacent radial sub-frames, and wherein the innermost blunt end portions of the superior radial sub-frames are interconnected to define a primary hexagon structure at a centre of the perimeter frame, and the innermost blunt end portions of the inferior radial sub-frames are connected to a converging region of adjoining surfaces of each adjacent pair of superior radial sub-frames to define a secondary hexagon structure around the primary hexagon structure, and wherein the overhang end portions and the outermost blunt end portions define six corners of a hexagonal perimeter frame.

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.

The present anti-ballistic shelter is a reinforced unit configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each end and side wall of the unit is reinforced with wall studs that penetrate the unit's structural framework. Even though these wail studs are welded into place, penetration of the wall studs into the framework ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

A ductile anchor attachment (DAA) mechanism is disclosed. Example embodiments are directed to a DAA fuse plate including a bottom section configured to connect to an existing anchor; a tapered lower section; a narrowed neck forming a ductile yield mechanism; a tapered upper section; and a connection mechanism for direct removable coupling of the DAA fuse plate to a structure being anchored, the connection mechanism being in contact with the tapered upper section of the DAA fuse plate, the DAA fuse plate in combination with the connection mechanism being configured to not buckle under compression forces and to adjustably dissipate tension forces acting on the structure being anchored.

A connection assembly for modular construction includes an upper junction connector coupled to an upper end of a column. The upper junction connector includes an upper end that has a planar upper surface, a recessed surface, and at least one connector sidewall extending between the upper surface and the recessed surface. The recessed surface and the at least one connector sidewall define a contiguous recessed area in the upper end that extends to second, third, and fourth edges of the upper end of the connector. A slot extends through the upper end adjacent to an interior surface of a column sidewall. A transverse bore extends through the first column sidewall proximate to and aligned with the slot.

A beam-column node structure of the steel prefabricated building is provided. The structure includes inner sleeves and driving components. The inner sleeves are slidably embedded in the transverse sleeves of the cross beam or node member; the driving components are used to drive the inner sleeves to move from one of the cross beams and the transverse sleeves embedded with the inner sleeves to the other. The inner sleeves are partly located in the crossbeams and partly in the lateral sleeves, and then the internal connection between the crossbeams and the lateral sleeves can be realized by the fasteners.
