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 prefabricated column assembly includes a hollow tubular column having a longitudinal axis. A gusset plate assembly includes a plurality of gusset plates connected to the column and extending laterally outward from the column in planes generally parallel to the longitudinal axis of the column. A first pair of the gusset plates extends laterally outward from the column along a first axis and defines a space for receiving an end portion of a first beam for mounting the first beam on the first pair of gusset plates. A second pair of the gusset plates extends laterally outward from the column along a second axis that is nonparallel and non-coincident with the first axis. The second pair of gusset plates defines a space for receiving an end portion of a second beam for mounting the second beam on the second pair of gusset plates to provide a bi-axial joint connection.

One aspect of one embodiment of the present invention is a frame system for modular berthing compartments wherein a plurality of the frames can also function as a frame for a modular tent system, which frames are assembled on site and easily transportable and optimized to ship very efficiently disassembled. The assembled frame creates an environment that maximizes the volumetric space to provide sleeping accommodation or utility spaces in a high-density configuration.

A building structure including a first building member and a second building member may be connected by a plurality of fasteners, each fastener having a head, a threaded portion having a through hardness of between HRB 70 and HRC 40, a thread-forming portion of at least HRC 50 hardness enabling the fastener to form threads in at least the second steel building member, and a fluted lead portion of at least HRC 50 hardness with a nominal diameter between 70 and 95% of major diameter, such that the fastener is capable of providing a ratio of strip torque to thread-forming torque of at least 3.0 and a ratio of strip torque to drive torque greater than 6.0 when the second steel building member having a thickness of 0.25 inch and the fluted lead portion having at least one diameter within nominal diameter between 80 and 98% of major diameter.

Embodiments are directed to structural fuses, structures including the same, and methods of using and forming the same. In an embodiment, a structural fuse is disclosed. The structural fuse includes a first attachment region defining one or more first bolt holes, a second attachment region defining one or more second bolt holes, and a yielding region between the first attachment region and the second attachment region. The yielding region defines one or more slots exhibiting an elongated shape.

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.

The present invention relates to a steel structure assembling system. The steel structure assembling system applied to assemble a movable steel beam and a fixed steel structure includes a rotating control device disposed on the movable steel beam for adjusting a relative position of the movable steel beam with respect to the fixed steel structure; an alignment target disposed on the fixed steel structure; and an image sensor disposed on the movable steel beam, sensing a target image of the alignment target and transmitting the target image to a ground operator to render the ground operator to operate the rotating control device to adjust the relative position of the movable steel beam in accordance with the acquired target image.

An orthogonal framework for the fabrication of modular buildings includes a plurality of hub members formed to fit in the ends of vertical hollow post members including base hubs for securing the lower end of a hollow post to a foundation and/or base beams or shear panels, terminal hubs for securing the top ends of a post upper beam members and/or the upper ends of shear panels, and intermediate tubes for securing the ends of two vertically aligned posts together and/or to support beams for the building. The hubs are hollow and have press nuts mounted on their inner surfaces to allow the terminals to be bolted to the posts, beams and shear panels in a large variety of beam and post combinations to form modular buildings in various configurations.

A connector for coupling a first column segment having a first inner surface and a first end surface to a second column segment having a second inner surface and a second end surface such that the end surfaces are adjacent one another is provided. The connector includes a plurality of fasteners and a plurality of plates each having a front face, a rear face, and a plurality of fastener apertures extending from the front face toward the rear face. Each of the fastener apertures is sized to receive one of the fasteners when coupling the first column segment to the second column segment such that the plates are spaced apart from one another. Each of the front faces is contoured to seat flush against the first inner surface and the second inner surface when the plates span the adjacent end surfaces of the coupled-together column segments.
