BACKGROUND
Field of the invention:
[0001] The subject matter in general relates to construction technologies. More particularly, the subject matter relates to prefabricated structural members used in composite construction.
Description of related art:
[0002] Steel members are one of the most important elements used in the construction of framed buildings. These members can be composite members which are structural steel members that are generally formed and filled with concrete to form a stable composite structure.
[0003] Conventionally, steel reinforcement within composite structural members comprise multiple steel reinforcing steel rods held together using reinforcing steel ties or other means to form reinforcing steel cages. Typically reinforcing steel is installed at the construction site. This takes up a lot of space at the construction site and takes up a lot of construction time to complete.
Considering the ever-growing need for residential and commercial buildings, cities are already cramped for space to build buildings, let alone space for constructing reinforcing cages at the site of construction.
Considering the ever-growing need for residential and commercial buildings, cities are already cramped for space to build buildings, let alone space for constructing reinforcing cages at the site of construction.
[0004] Further, there is a dearth of skilled labours in the construction industry who can place the reinforcing steel at the required place during the construction program. Additionally, as the height of construction increases, the placement of reinforcing steel becomes logistically more challenging. Conventionally, the reinforcing steel cages are nested on top of each other as the height of construction increases. This again requires skilled labour and time. All of this contributes to increase in expenditure.
[0005] Considering the foregoing discussion there is a need for an improved system for providing reinforcing steel to composite steel and concrete structures.
