A self-locking connection system for modular construction (e.g., MiC and PPVC) is provided for interlocking an upper module column to a lower module column. A horizontal load transfer plate has first and second inner sleeve portions positioned beneath and above the plate. The sleeves are configured and dimensioned to be received within the respective module columns. Spring-loaded latches in both sleeve portions engage respective column receiving apertures. Each latch may include a latch plate having a wedge-shaped latch protrusion connecting to a vertical latch surface. The latch plate has one or more latch plate apertures for receiving a rod within a coil spring. An optional second reversible self-locking mechanism interlocks the connected modules to a building load-bearing support such as a core wall. The second self-locking mechanism includes an angled protrusion extending from the horizontal load transfer plate to mate with a protrusion-receiving structure embedded in the load-bearing support.

The present invention provides a construction frame comprising a front side, a back side, and a side part, wherein said construction frame further at least one receptacle in the side part. Further, a system comprising at least one construction frame according to the invention is provided. In a preferred embodiment said system comprises at least two construction frames which are connected by at least one connector, which is inserted in the at least one receptacle of each construction frame.

A locating pin assembly for coupling a first modular frame to a second modular frame is disclosed. The locating pin assembly has a first gusset plate positioned between the first modular frame and the second modular frame. The first gusset plate has a first gusset plate aperture and a second gusset plate aperture for receiving fastening means for coupling the first-modular-frame-first-beam and the second-modular-frame-first-beam the gusset plate. The pin assembly also has a pin engaging the first gusset plate, the first modular frame and the second modular frame. Also disclosed are modular frame units having the pin assembly, system of modular frame units having the pin assembly and a method of coupling modular frame units.

A tripartite tension rod assembly, including a first vertical telescoping tension rod, the first tension rod having a first spring loaded endcap and a second non-spring-loaded foot, the first tension rod having a first longitudinal axis; a second vertical telescoping tension rod, the second tension rod having a first spring loaded endcap and a second non-spring-loaded foot, the second tension rod having a second longitudinal axis; a first arcuate bracket arranged to be fixedly secured to the first vertical tension rod; a second arcuate bracket arranged to be fixedly secured to the second vertical tension rod; and, a horizontal telescoping rod extending between the first and second arcuate brackets, the horizontal rod having a third longitudinal axis which, when assembled, is substantially perpendicular to the first and second longitudinal axes.

A standardized structural metal plug assembly that, when welded to metal columns and beams, allows to join them together into a bi-axial moment connection without bolts or on-site welding. The plug is assembled in a gravity and interlocking fashion. It is composed of one flange cruciform joint that works as a “male” outward component that channels the beam's “female” inward bracket into its seated and locked position. The column terminals also act as “female” inward component that slips and seats over the flange cruciform joint ends. All the components are lock-in-place to the flange cruciform joint due to various mechanical locking latches attached to the beam brackets and column terminals.

An assembled structure system includes a prefabricated member, a fastener and a locking member. The prefabricated member is provided with at least one cavity, and the fastener is assembled in the at least one cavity. At least one fastener is assembled in each cavity. The cavity includes an upper end surface, a lower end surface, a left end surface and a right end surface. The left end surface or the right end surface includes a vertical surface perpendicularly connected to the upper end surface and an inclined surface connected to the vertical surface. A connection angle between the vertical surface and the outer side of the inclined surface forms an obtuse angle. The inclined surface is connected to the lower end surface. The fastener includes a fixed surface, two side surfaces and a bottom surface. The fixed surface, the two side surfaces and the bottom surface are hingedly connected.

The present disclosure generally relates to an elongated section (101) for construction structures (300). The elongated section (101) comprises a plurality of sides (102), each side (102) comprising a first retaining channel (104) and a second retaining channel (105) adjacent a respective corner (106) of the elongated section (101), the first and second retaining channels (104,105) being a minor image of each other. Each retaining channel (104,105) is configured for engaging a respective retaining member (201) for supporting a structural panel (301) between the retaining members (201). Each retaining channel (104,105) comprises a channel slot (197) extending perpendicularly into the side (102), the channel slot (197) for engaging a first end (204) of the respective retaining member (201); and a channel end (198) opposite to the channel slot (197) for engaging a second end (206) of the respective retaining member (201).
