Definitions

  • Embodiments of the invention relate to Prefabricated Prefinished Volumetric Construction (PPVC) and more specifically to prefabricated volumetric modules comprising of prefabricated profiled wall panels, floor and ceiling slabs assembled by means of mechanical joints; and to a method of installing the same on a building under construction with conventional reinforced concrete structural frame and design to integrate the prefabricated volumetric modules for greater structural reliability and designers’ and end-users’ flexibility.
  • PPVC Prefinished Volumetric Construction
  • Prefabricated Prefinished Volumetric Construction is a relatively new construction method introduced to the construction industry to enhance construction productivity and quality.
  • This construction technique requires building modules to be fabricated and finished off-site in a factory, before they are delivered to the construction site for installation on a building under construction. After positioned in place, the building modules are connected and integrated as parts of the building with structural continuity transferring loads and providing structural stability to the building.
  • a prefabricated volumetric module may comprise both structural and non-structural elements such as walls, columns, beams, slabs and/or fagade.
  • the walls, columns, beams and slabs can be constructed from materials such as concrete, Reinforced Concrete (RC), Steel-Concrete Composite (SCC), High Performance Cementitious Composite (HPCC), Ultra-High Performance Concrete (UHPC) or steel, while the fagade can be constructed of cement-based panels, aluminium panels or curtain wall systems, as specified by the designer and/or end-user.
  • volumetric modules include (i) the use of conventional RC walls, columns, beams and/or slab which can be cast monolithically or in several operations with cold-joints to form the volumetric module, (ii) the use of RC walls, columns, beams, RC or SCC slab with walls infilled with prefabricated cement- based or calcium silicate panels to form the volumetric module and (iii) the use of structural steel frame, RC or SCC slab with wall infilled with prefabricated cement-based or calcium silicate panels to form the volumetric module.
  • a prefabricated volumetric module is typically completed with finishes for walls, floors and ceiling before it is delivered to the construction site for installation.
  • the prefabricated volumetric module Upon delivery to the construction site, the prefabricated volumetric module is hoisted using lifting equipment to position it on a building under construction, where it is connected and integrated as parts of the building with structural continuity transferring loads and providing structural stability to the building.
  • there are two methods for connecting and integrating these prefabricated volumetric modules with the building namely through, (i) the use of steel connectors attached to the structural elements of the prefabricated volumetric modules and building; or (ii) the use of cement-based grout to bond over-lapping steel reinforcements and/or steel reinforcements spliced using steel connectors.
  • the invention aims to provide a light-weight prefabricated volumetric module (aka PPVC module) that can be fabricated by producing discrete wall panels, floor and ceiling slabs and assembling them quickly using mechanical fasteners; a method of installing the same on a building under construction with greater tolerance to construction dimensional errors using simple concreting technique that is reliable and cost effective; and a structural system for connecting and integrating such PPVC modules with the building that provides greater flexibility for designer and/or end-user to modify the building unit layout.

  • the profiled concrete wall panels are adapted to be part of a formwork system at the locations of the beam, column and/or wall positions to receive fresh concrete after such PPVC modules and reinforcements are positioned in place on the building.
  • This ensures vertical and horizontal continuity of the PPVC modules with transfer of vertical and horizontal forces to the building foundations and lateral force resisting members, respectively.
  • Segments of the profiled concrete wall panels may be designed to be removable at locations away from the columns and/or walls to provide greater flexibility for the designer and/or end-user to modify the building unit layout.
  • the profiled concrete wall panels may be strengthened with steel sections to withstand the concrete hydrostatic pressure during casting, where necessary.
  • the profiled concrete ceiling slab is adapted to be part of the formwork system at the locations of the beam, column and/or wall positions to receive fresh concrete after the PPVC modules and reinforcements are positioned in place on the building.
  • This ensures vertical and horizontal continuity of the PPVC modules with transfer of vertical and horizontal forces to the building foundations and lateral force resisting members, respectively.
  • the profiled ceiling slab is designed to withstand imposed construction loads before the upper PPVC module is positioned in place or to support the RC roof slab concreting works.
