A modular unit connection system for jointing together pre-fabricated rectangular modular building units to form a multistory building. The building units can be completely fitted out and this connection system allows for positive structural connection using liquid grout filled columns, without bolting or welding and without the requirement for access to the connections from inside the pre-finished building module interiors. The four corner columns of the box-shaped modules are steel square hollow sections. This connection system uses a unique connector tube passing from the bottom of the column above, through a horizontal connector plate containing a guidance system and into the top of the hollow column below, and then a system of grouting the inside of the column, from an access position on top the upper most module to form the final positive structural connection.

A hybrid shear wall system for construction of massive timber buildings of more than two stories in seismic zones, is provided, which presents a ductile behavior and reduced overturning effect against a lateral load caused by destructive natural events, such as earthquakes or strong winds; the shear wall system comprises an interior frame with articulated nodes of union between columns and sills, to which exterior massive timber panels are joined on both opposite faces, by means of individual energy dissipating connectors; where the frame comprises post-tensioned self-centering means, which together with the articulated nodes, the exterior massive timber panels and the connectors, act together as a unit and allow the shear wall to behave in a ductile manner and with reduced overturning effect under high lateral load.

A system for providing an angled construction or bent beam construction. Such system may include a first beam comprising a first elongated beam segment having a first interlocking joint portion at one end, and a second beam comprising a second elongated beam segment having a second interlocking joint at one end, wherein the first interlocking joint portion is configured to rotatably couple to the second interlocking joint to form a rotatable joint such that the angle between the first beam and the second beam is adjustable.

A modular home connector includes a main portion, wherein the main portion is formed via a first side, a second side, and a third side, wherein the first side and the second side are opposite of one another and substantially parallel with one another, wherein one or more ends of the first side and second side include a first angle with respect to the third side and at a perimeter of the first side or second side, wherein the first and second side are met by the third side, wherein the top perimeter of a first main portion aligns with the bottom perimeter of a second main portion, and a connector portion, wherein the connector portion includes a corresponding second angle to adjoin against a top perimeter of each side of the main portion and configured to connect two or more main portions via the connector portion.

The present application relates to a prefabricated concrete beam-column node and a construction method thereof. The construction method of the prefabricated concrete beam-column node includes: assembling node connectors, and mounting studs on each node connector; welding a circumferential reinforcing plate with a groove hole in the center to a middle-rear section of each node connector; mounting a longitudinal rebar on each circumferential reinforcing plate; pouring a concrete beam between two circumferential reinforcing plates; welding a hidden corbel to a side flange of each of structural columns; hoisting the concrete beam, and overlapping each node connector with the corresponding hidden corbel; welding each node connector to the corresponding structural column; and pouring the concrete beam between the circumferential reinforcing plates and the structural columns.

A connector assembly, which in one embodiment has an upper connector and in another embodiment has a lower connector. The assembly can have a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly. Also, a system for coupling adjacent modular frame units for forming a modular building and a method for coupling modular frame units for forming a modular building are provided.

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.

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.
