  • the present invention relates to an apparatus for coupling prefinished prefabricated volumetric construction (PPVC) units.
  • PPVC volumetric construction
  • Prefinished prefabricated volumetric construction (PPVC) units are currently being used to quickly and efficiently construct buildings. This construction technique requires neighbouring units to be coupled together. Any such couplings need to ensure adequate structural continuity between adjacent modules. It is generally desirable to provide an effective and cost efficient module connection system.
  • PPVC volumetric construction
  • connections are not be directly accessible to the workers from the outside of the module.
  • PPVC modules are often prefinished with the fire proofing board and finishing material. As such, heavy structural work is difficult to undertake within the module. Therefore connections can often only be achieved working from the top of the modules, which is the only face of the modules from which access can be gained to connections between structural elements not located at the perimeter of the PPVC building.
  • This type of connection requires access from outside as well as inside the modules. The internal access must be achieved through the finishing and fireproofing material installed within the modules. This system provides neither guidance for final module positioning and nor accurate positioning of the element during its installation. This type of connection provides very little protection with regards to corrosion and is only well suited for open steel sections which allow recesses which can accommodate the plate sleeves.
  • connections are accessed from the top of the modules, through columns that consist of hollow sections. Hence they do not require access panels and can be implemented anywhere along the module sides. This type of connection cannot be protected against corrosion as they are machined, unless they are manufactured of corrosion resistant material. This type of connection also has very little installation tolerance. These pieces are expensive to produce because of the milling and machining required and overall cost can be prohibitive as single project requires a large number of connections.
  • the main functions provided by these mechanical couplers are:
  • an apparatus for coupling prefinished prefabricated volumetric construction (PPVC) units including first and second parallel inserts laterally displaced by a bridging member, the first and second inserts being coupleable to respective upper sections of columns of first adjacent PPVC units to thereby couple the units together, wherein the first and second inserts each include a plurality of vanes extending radially from a central axis towards respective inner peripheral sections of respective columns.
  • PPVC volumetric construction
  • the vanes include chamfered edges for facilitating insertion into respective columns of the units.
  • the bridging member is a plate, including first and second slots separated by a spacing section, wherein the inserts extend normally through respective slots, and wherein the vanes extend radially out to meet and engage with respective inner peripheral sections of the first and second slots.
  • the vanes extend radially out from a central axis to meet and engage with said respective inner peripheral sections of respective upper sections of columns.
  • the bridging member is a parallelepiped plate, with opposed ends being coupled to respective ones of the inserts.
  • the bridging member is coupled between apexes defined by neighbouring vanes of respective inserts.
