Definitions

  • This invention relates to a reinforcing framework capable of prefabrication in an off-site location.
  • the reinforcing framework can be subsequently transported to a building site location for instalment and use in the formation of reinforced concrete slabs in the construction of a building.
  • Composite materials are widely used in the construction industry to form reinforced structures, for many reasons including durability, strength, tensile and thermal properties as well as flexibility in construction of various components and structures. It is to be appreciated that while concrete is an often used and popular choice for use in reinforced structures, other materials with similar physical properties, such as tensile strength and ductility, may be substituted.
  • Reinforcement of concrete or similar material is often achieved by embedding a skeletal framework formed of reinforcing materials made of steel, polymers, fibre glass, or alternate composite material into the concrete or similar material.
  • reinforcing materials made of steel, polymers, fibre glass, or alternate composite material.
  • rebar steel reinforcing bars
  • Shear reinforcement is required to resist the effects of sheer or diagonal stress on a material, such as concrete.
  • shear links are often added to reinforcing frame work to counter shear stress.
  • the length of the reinforcing materials used in skeletal frameworks can be adjusted by splicing two reinforcing materials, such as rebar, together. Splicing allows for shear stress to be transferred from one rebar to another. Splicing can be achieved by lapping the bars, using a mechanical joint, or welding the bars together where they join or overlap. Preferably splicing of bars is performed on alternate bars with up to 50% of reinforcement bars spliced in any given section of a reinforcing structure.
  • Reinforced concrete is used to build many different types of structures and components of structures including, slabs, walls, floors, beams, columns, foundations and frames.
  • a small change in the design of a reinforced structure can have significant impact on material costs, construction schedule, and ultimate strength, as well as operating costs, occupancy levels and end use of a building.
  • Reinforced concrete can be classified as precast or cast-in-place concrete.
  • the loose rebar takes time to be loaded and unloaded from the vehicular transportation, meaning that there is increased disturbance at the offsite and onsite locations, as greater time is needed to complete the loading or offloading task. This issue is even more evident at onsite locations positioned on a busy road.
  • fixers require substantial crane time to complete the manual fixation of bars in place meaning that there is increased downtime in construction, particularly for other build projects that require a crane to complete.
  • a standard 1000 square foot reinforcing framework will require around 8 to 9 fixers and will take the 8 to 9 fixers about 5 to 6 working days to complete the reinforcing framework ready for concrete to be poured over the framework.
  • the buildings and construction industry is under pressure to deliver faster, more cost-effective builds and build designs without compromising the quality, strength and durability of the end product.
  • single mesh layers are limited in the scope, complexity, and in particular, the size of reinforcing structures that can be created. It is an object of the present invention to provide alternative skeletal framework designs for reinforced structures that are capable of enabling larger reinforcing structures to be constructed.
  • a reinforcing framework for the construction of reinforced concrete structures including:
  • the length of the cross member is sufficient to support a plurality of reinforcing bars.
  • the spacing between the legs is greater than the spacing between adjacent parallel spaced-apart reinforcing bars of the mesh layer which engages the cross member.
  • the cross member is curved inwardly between the legs.
  • the cross member is V-shaped.
  • each spacer has feet which project outwardly from the legs in opposite directions.
  • a spacer is mounted at a lifting point for the reinforcing framework.
  • a plurality of spaced-apart splice bars project outwardly at one or both sides of the frame.
  • the splice bars form an extension of one or both of the mesh layers. This arrangement facilitates automatic splicing of adjacent reinforcing frameworks during construction.
  • One advantage of the new reinforcing framework of the present invention is that reinforcing frameworks comprising elongate members with a diameter of 10mm or more can now be prefabricated in an offsite location.
  • Another advantage of the new reinforcing framework is that the design can be pre-approved by an engineer who has greater access for inspection.
  • a further advantage of the new reinforcing framework of the present invention is that is capable of being produced in a controlled factory environment with standardised equipment set up and standardised methods and approach to construction.
  • Another advantage of the new reinforcing framework is that build time onsite is greatly reduced with typical installation time taking minutes to hours to complete compared with the days to weeks' timeframe endured using traditional designs and manual assembly and installation techniques. Delivery and installation time is reduced by around 70% with no onsite labour required for fixing thereby increasing labour efficiency and decreasing labour costs associated with this task.
  • a further advantage of the new reinforcing framework of the present invention is that there are fewer disturbances to other onsite activities and to the surrounding area affected by the building project, as the fully assembled reinforcing framework of the present invention can be loaded and unloaded from the vehicular transportation swiftly.
  • a further advantage of the new reinforcing framework of the present invention is that monopoly of a crane for the purpose of assembling a reinforcing framework onsite by traditional fixing means is mitigated as the new reinforcing framework of the present invention arrives at the onsite location, fully assembled and ready to install and use.
  • a further advantage of the new reinforcing framework of the present invention is that monopoly of the crane for the purpose of loading and unloading the reinforcing framework and placing the reinforcing framework into the desired location for installation and use, is reduced.
  • a further advantage of the new reinforcing framework of the present invention is that the monopoly of skilled labour or manpower as traditionally required in assembling a reinforcing framework onsite by traditional fixing means, is mitigated as the new reinforcing framework of the present invention arrives at the onsite location, fully assembled and ready to install and use.
  • a further advantage of the new reinforcing framework of the present invention is that the health safety and wellbeing of onsite labour is improved.
  • a further advantage of the new reinforcing framework of the present invention is that productivity of the reinforcing framework made in factory environments is increased.
  • a further advantage of the new reinforcing framework is that it provides a standardised construction approach with improved accuracy and consistency in building the reinforcing framework on which the completed reinforcing structure such as, but not limited to, a slab design, is made.
  • a further advantage to the new reinforcing framework of the present invention is that by combining more than one mesh layer together, separated by a spacer, enables larger reinforcing structures to be constructed with rebar elements having diameters of up to 40mm.
  • the cross member is curved such as to allow a gap to be formed between the cross member and the mesh layer engaged therewith.
  • the gap formed between the cross member and the first mesh layer is generally positioned at a substantially midway point along the cross member and between proximal and distal ends of the cross member.
  • curve in the cross member allows for ease of access through the gap positioned between the cross member and to the two sets of elongate members present in the first mesh layer such that it allows at least one bar to be placed between the two sets of elongate members present in the first mesh layer.
  • a further advantage of the curve in the cross member is that the curve allows for additional reinforcing bars to be added once the reinforcing framework has been fully assembled.
  • a further advantage of the curve in the cross member is that the curve allows for ease of access to enable the additional bars to be spliced together with the existing elongate members of the first mesh layer once the reinforcing framework has been fully assembled.
  • any and all details pertaining to the second set of elongate members may also equally be applied to the first set of elongate members.
  • any and all details pertaining to the first mesh layer may equally be applied to the second mesh layer.
  • the mesh layers are interchangeable in this regard.
  • the at least one bar may be placed evenly throughout the first mesh layer and adjacent to one or more elongate member.
  • more than one bar is placed, namely a first bar and a second bar, such that the first bar is placed at a distance of approx. 500mm c ⁇ c from the second bar.
  • the curve of the cross member is any angle from 1° to 45°.
  • the curve of the cross member is any angle from 5° to 30°.
  • the curve of the cross member is any angle from 8° to 15°.
  • a further advantage of the curve in the cross member is that splicing together the two sets of elongate members, present in the first mesh layer, where the first set of elongate members engage the second sets of elongate members, can be performed easily. Such positions, where the first set of elongate members engage the second set of elongate members, as spliced together may further be referred to as joints.
  • the at least one contact point is substantially adjacent to the distal or proximal ends of the cross member.
  • the cross member comprises at least two contact points.
  • contact points provides clearly defined positions on the first mesh layer that provide improved purchase, such that the fully assembled reinforcing framework may be lifted about the contact points from the vehicular transportation to the desired position for final instalment and use.
  • Such contact points may also be referred to as lifting points.
  • a further advantage of the contact points is that the contact points enable multiple fully assembled reinforcing frameworks to be lifted from the vehicular transportation to the desired position for instalment and use. Being able to lift multiple fully assembled reinforcing frameworks in a single lift means that the time taken to load and unload the reinforcing framework is greatly reduced and less disturbance of other onsite activities.
  • a further advantage of the contact points is that, due to the reduced number of lifts required to load or unload the fully assembled reinforcing frameworks, the crane time needed is significantly reduced freeing up the crane for other onsite jobs or projects. This has a positive impact on overall build time meaning that the construction project can be completed in a shorter time period.
  • cross member, the leg portion and the foot portion are all mutually orthogonal.
  • each of the first mesh layer and second mesh layer comprise at least two sets of elongated members, namely a first set and a second set.
  • One advantage of the present invention is that the diameters of the elongate members, used in constructing the mesh layers, namely the first mesh layer and the second mesh layer, can range from 10mm to 100mm.
  • the diameters of the elongate members, used in constructing the mesh layers, namely the first mesh layer and the second mesh layer range between 10mm to 70mm.
  • the diameters of the elongate members, used in constructing the mesh layers, namely the first mesh layer and the second mesh layer range between 10mm to 50mm.
  • the diameters of the elongate members, used in constructing the mesh layers, namely the first mesh layer and the second mesh layer range between 10mm to 40mm.
  • first set of elongated members and the second set of elongate members are positioned substantially perpendicular to one another.
  • first set of elongate members are arranged in pairs, each pair of elongate members being positioned substantially in parallel to the next pair of elongate members.
  • each elongate member differs in length.
  • One advantage to having differing lengths of elongate members is that it allows for greater flexibility in the design of different types of reinforcing structures.
  • a further advantage to having differing lengths of elongate members is that it allows for designs to be adjusted to fit onsite dimensions.
  • each pair of elongate members one elongate member is substantially shorter than the other elongate member that makes up the pair.
  • At least a proportion of the individual components that make up the reinforcing framework are made from one or more of steel, rebar, polymers, fibre glass and alternate composite material or any combination thereof.
  • the present invention is further directed towards a method of fabricating and installing the reinforcing framework in the construction of reinforcing structures comprising prefabrication of the reinforcing framework in an off-site location; transporting and delivering a complete assembly of the fabricated reinforcing framework to the site; instalment of the reinforcing framework by lifting the complete assembly into the desired position; and, applying concrete to the reinforcing framework.
  • One advantage of the method of fabricating and installing reinforcing framework of the present invention is that production in a controlled factory environment with standardised equipment set up and standardised methods and approach to construction enables a fast and efficient turnaround of production of individual components and the fully assembled reinforcing structure.
  • the method of fabricating and installing reinforcing framework with standardised equipment set up can speed up production of the fully assembled reinforcing structure by being continually present and in the desired position ready for assembly purposes. It is to be appreciated that during onsite fabrication of similar reinforcing frameworks the equipment is often moved and repositioned for the purpose of other onsite jobs, meaning that the fabrication is slowed as the equipment needs to be returned to the desired position for the purpose of fabricating reinforcing frameworks.
  • a further advantage of the method of fabricating and installing reinforcing framework of the present invention is that mass production is enabled.
  • the reinforcing framework of the present invention may be transportable at any length and width, and in particular any wide-load width or parameters as may be required or imposed by vehicular transportation.
  • the method comprises a drying step following the application of concrete, in particular when the concrete is cast-in-place.
  • the advantage of having a drying step is to set the concrete, or other similar material, hard and in place against the reinforcing framework to form a strong and robust reinforcing structure.
  • reinforcing frameworks of the present invention are for use in the construction of one or more reinforcing structures including, but not limited to, slabs, walls, floors, beams, columns, foundations and frames.
