A building information modeling (BIM)-based modular housing built with thin-wall channel steel can include columns and transverse beams adopt inward-flanging C-section steel or combined square steel arranged by oppositely buckling symmetric inward-flanging C-section steel. The columns and transverse beams are connected to each other together by base connectors, butting connectors, or crossed connectors. The joint is provided with webs, and can be used as a standard connector due to high strength, thereby realizing an internal-external nesting effect. A positioning groove arranged outside the joint and the inward-flanging C-section steel can be nested together in a concavo-convex manner, and then pressed and fastened by a fastening steel strip, thereby realizing effects of fastening and slippage prevention.

Each section of the first plurality of joined sections and the second plurality of joined sections has a pattern of apertures therein, and each section is foldable approximately perpendicular to an adjacent section. The pattern of apertures in a first section after folding is congruent with the pattern of apertures in a second section after folding, wherein the second section is parallel to the first section, after folding. An elongate member is arranged through the apertures of one or more sections of the planar member, after folding the sections of the planar member.

A full-moment column collar is disclosed, including four collar flange components and four collar corner components. Each collar flange component includes an upper transverse element and a lower transverse element, connected by a bridging member. Each collar corner component includes first and second expanses defining a corner and a standoff portion extending from the corner, the standoff portion having a distal T-shaped structure. Each collar corner component is configured to connect two adjacent collar flange components, and each collar corner component has a multi-axis alignment structure extending from a bottom end portion for vertically positioning a lower transverse element of a respective collar flange component.

A joining device (100) for precast reinforced concrete elements with a dry joint comprising a first group of joining reinforcements (10) arranged on a first plane and in parallel with one another, each one of said joining reinforcements (10) comprising one reinforcement (1) and two threaded ends (2). The device comprises first coupling means (30) for coupling to the columns (200) arranged between the joining reinforcements (10) and perpendicular to the first plane defined by the joining reinforcements (10) and a plurality of anchoring plates (20) arranged so as to define a closed frame inside of which the joining reinforcements (10) are arranged, and where the inner space defined by the anchoring plates (20) is filled with a structural filler material (concrete, resin, composite, etc.) (50). The anchoring plates (20) comprise a plurality of holes (21), at least one for each threaded end (2), in a position that matches up with the latter, and through which the threaded ends (2) remain accessible. The device comprises second coupling means (40) between the threaded ends (2) and the beam (300) rebars.

A framework module for use in modular building construction comprises a plurality of elongate upright and cross beams, rigidly connected at or towards their ends to form a box frame with open side and end faces, and; at least one connection point on each of the upright beams which is configured to allow mutual connection with an equivalent connection point located on a substantially identical adjacent framework module, so that a plurality of framework modules can be connected together to form an open-web truss of vertically and horizontally aligned members.

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.

A joint assembly comprising; an engagement block having a plurality of insert receiving faces; each insert receiving face having a slot, and an aperture at a mid-point of said slot; a plurality of inserts each having a core, at least a pair of ribs projecting from said core, a coupling at an insertion end of the core and a mount at a mounting end of the core, and; a coupling pin; wherein said engagement block is arranged to receive the inserts, with said ribs received into the slots and said core received into said aperture, said coupling pin arranged to be inserted into said engagement block and couple with the couplings of said inserts so as to releasably fix the inserts to the engagement block.
