Definitions

  • the present system relates to the field of construction materials, particularly prefabricated or site-assembled decking sections.
  • Conventional metal decks are capable of covering spans in the range of 10 to 15 feet, while specialized deep metal decks can cover spans in the 20 to 30-foot range.
  • Slabs can offer greater spanning capability.
  • pre-stressed hollow concrete core slabs can typically span 20 to 40 feet.
  • Typical waffle slabs can span 20 to 30 feet, but those with added depth and weight can span approximately 50 feet.
  • Voided biaxial decks can span up to approximately 50 feet (60-feet if post-tensioned).
  • Non-composite, one-way action, constant cross-section, prefabricated roof decks e.g., Super Versa-Dek
  • Super Versa-Dek which are comprised of two specific deck types that are mechanically connected to each other between node points, can span approximately 30 feet for roof loading.
  • pre-stressed hollow concrete core slabs require a specialized fabrication facility and process, which can be time-consuming. Transporting these slabs to a job site also presents a challenge due to their weight and bulk. Once on-site, they are difficult to modify to accommodate building use or support utilities.
  • Typical naval and outer space structures are constructed by welding solid-plate elements together to form a surface skin.
  • the weight of these elements requires reinforcement with frequent internal compression framing and/or external tension rings.
  • these structures often require structural redundancy (e.g., double-hulled construction) and ductility to withstand unexpected collision forces. In such applications, there are clear advantages to using limited basic shapes that can be easily transported, assembled, and modified in the field.
  • the present system provides a system of components that can be efficiently combined to create desired structural members, including supporting beams.

  • the additional support elements 1508 can have any known, convenient and/or desired positioning and/or geometry and/or can be absent.
  • the support elements can act as temporary support structures during construction and/or can act as attachments for equipment that is adapted to lift decking into position during construction.
  • the present system offers several advantages. First, only simple and light-weight deck sections need to be kept in a manufacturer's inventory and when needed, they can be rapidly combined into the required complex sections.
  • the present system also offers variation in depth, solid portion width, steel gage and connection frequency, as well as concrete reinforcing along the span and perpendicular to span. This advantage, when combined with the light weight of the system, can enable it to cover longer spans than currently available systems and can reduce the need for intermediate support framing.
  • Spans can be increased and the shoring requirements and intermediate field beams can be eliminated.
  • end beams to support the reactions from the deck and transport them to the columns.
  • the ends of the decks can be detailed to form an integral beam when the concrete topping is poured in the field, which can eliminate the need for a separate supporting beam.
  • the present system can reduce the need for construction shoring, since the metal deck that forms the soffit, top, and web of the combined section can have adequate strength and stiffness to support the construction loads for non- composite construction and also until the concrete hardens for composite construction.
  • curved surfaces along the span and perpendicular to the span can be achieved, as well as flat finished surfaces at the top or soffit.
  • shallow barrel vault arches as well as shallow dome construction are possible. This can be advantageous for roofs due to the inherent strength of arch systems and the resulting efficiency of drainage systems for the roof. Further, articulated soffit or roof configurations can also be achieved if desired for aesthetic effects or functional reasons.
  • Another advantage of the present system is that it can facilitate utility placement in the structure. With the present system, large utilities can be accommodated within the structural depth of the deck. Moreover, the utilities can run in two perpendicular directions within the structural depth, and access to utility chases can be easily
  • the present system also offers several advantages for the specialized construction of marine and outer-space structures. Compared to typical marine and/or outer- space structures which use solid plate elements for their skin structures, the proposed steel deck can provide reduction in total weight due to its more efficient use of material (structural depth) which can reduce the need for frequent internal compression framing and/or external tension rings. Moreover, the present system, due to its cellular structure, can have more redundancy, and ductility in the case of damage from unexpected impact and/or collision forces. Finally, filling the cells with light-weight foaming material can seal and provide buoyancy for naval structures.
  • the system When applied to outer-space structures, the system can be used as a two-way platform where it is not subject to any differential internal/external pressure, such as for a support structure for solar panels.
  • the deck can be formed into a cylindrical type structure with external tension rings placed as required.
  • the first inner layer e.g., a cellular deck
  • the deck voids can additionally be filled with a lightweight foaming material and/or liquid sealant to provide additional sealing surfaces in case a small puncture occurs.
  • the present system can be used to create wall spans as well as decking spans.
  • the present system can offer flexibility in designing walls with various cross-sections to withstand shear forces, compression loads, and any other known, unknown, constant, or variable forces.
