Definitions

  • the present invention relates broadly to the building and construction industries. More particularly, the invention relates to an improved building column.
  • 'column' is understood to include reference to any one or more of the terms 'column, pile, pillar, support, post, shaft or the like'.
  • column fabrication process must be duplicated on site in order to fabricate each individual column on each floor of a building or structure. Accordingly, column fabrication is a very time consuming and labour intensive task when constructing multi-storey buildings incorporating a large number of columns.
  • the present invention relates to a concrete column.
  • the column includes at least one longitudinally extending steel reinforcement bar and a void extending inwardly from the column outer surface.
  • the void exposes a section of at least one steel reinforcement bar for enabling connection of a separate structure to the column.
  • the void also defines a support surface for supporting the separate structure.
  • the column of the present invention has been especially designed for use in a building or other structure as a load bearing column.
  • the column may alternatively be used in a non-load bearing application.
  • the column may be used in a decorative and substantially non-load bearing application.
  • reinforcement bars provided in a column will be dependent on the dimensions, mass and intended application of the column.
  • building columns typically include a plurality of longitudinally extending and spaced steel reinforcement bars to provide sufficient column strength.
  • Circumferentially extending steel reinforcement rings or spirals may also be provided, and may be connected to the longitudinally extending bars within the void area to create a stronger column and a stronger structure
  • the column may be solid. However, in a particularly preferred form the column includes a longitudinally extending bore, which may be utilised as, for example, a services duct for power, fresh or waste water.
  • the exposure of a section of at least one reinforcement bar provides an effective site (or sites) for attachment of one or more structures to the column for support by column.
  • a section of a reinforcement bar provides an effective site for the connection of a beam (or other suitable structure) to the column.
  • the other end of the beam may be connected in a similar manner to a second, similar column to thereby support the beam in a generally horizontal orientation between the two upstanding columns.
  • Such an arrangement may be used to support a band beam (or similar) between two building columns for supporting a floor structure in a multi-storey building.
  • the void divides the column into two longitudinally extending and coaxial column sections. With the column standing upright, each column section may approximately correspond to the height of a single building floor. Accordingly, the column of the present application may be used to replace two conventional, separate and coaxially arranged support columns being used one immediately above the other in a multi-storey building application. In such an arrangement, each column section would approximately correspond to the height of a conventional single floor support column.
  • the column may include two voids, with the voids spaced longitudinally along the column and dividing the column into three coaxial column sections.
  • Each of the three column sections may be used to replace three conventional, separate and coaxial support columns.
  • the column of the present invention may be manufactured in a size and form to replace any number of conventional and coaxially arranged support columns, within practical strength, handling and transport sizing limits.
  • the void may be of any suitable shape.
  • the void extends inwardly from the column outer surface through the column and exposes a section of each reinforcement bar extending longitudinally through the column at the location of the void.
  • the void may extend completely through the column to create an interruption or discontinuity in the concrete of the column. Such an arrangement advantageously allows full punching shear stress to be attained, which is preferred in spun concrete columns.
  • the column void(s) allows some or all of a cast in- situ beam or slab longitudinal (horizontal) reinforcement to pass through the column unhindered. This avoids direct reinforcement connection, reinforcement overlapping and minimises reinforcement congestion at the column/beam joint.
  • One end of the column is defined as a lower end and preferably includes a securing means for securing the lower end of the column, when upstanding, to a footing or other support structure.
  • the lower end of the column may include a height adjustment means.
  • the height adjustment means enables the space, if any, between the lower end of the column and the upper surface of the footing (or other support structure) to be altered, to thereby alter the effective column height relative to the footing. Provision of a height adjustment means advantageously accommodates, within practical limits, any intolerance(s) that may arise in the building fabrication and/or other construction stages.
  • the securing means and the height adjustment means may be integrated.
  • the upper end of the column may also include a securing means for securing the upper end of the column to a roof (or other) structure.

  • the column 10 includes a longitudinal bore 18, defining an inner surface 20.
  • the column 10 is illustrated in a horizontal orientation, as required to lift the column 10 by crane when manoeuvring the column 10 into its final upstanding position at an installation site.
  • the column 10 is designed such that the lower end 12 is secured to and supported on a building foundation.
  • the lower end 12 may be secured to and supported on a support column provided on the floor immediately below.
  • the column 10 includes a plurality of steel reinforcement bars 22 extending longitudinally through the column 10.
  • the reinforcement bars 22 are provided in a generally equidistantly spaced and parallel arrangement within the column 10.
  • the column 10 includes two voids 24,26 in the form of column discontinuities or interruptions, each of which extends cross-sectionally all the way through the column 10.
  • the provision- of the voids 24,26 defines three separate and distinct concrete column sections 28,30,32. It is to be appreciated that the column sections 28,30 are interconnected solely by the reinforcement bars 22 extending longitudinally though the column 10. Likewise, the column sections 30,32 are also interconnected solely by the reinforcement bars 22 extending through the column 10.
  • Spiral-shaped reinforcement 23 circumferentially extends around the reinforcement bars 22 in the voids 24,26 (but illustrated only in void 24). This may be used to maximise the void strength during installation, or to provide in- service shear strength.
  • the reinforcement bars are generally configured such that the column 10 can be installed without the need for additional support at the voids 24,26. This allows for a simple 'lift and place' of the column 10 without any further work, such as unbolting of braces across the voids 24,26.
  • voids 24,26 extend cross-sectionally all the way through the column 10, voids extending only part-way through the column 10 are also contemplated.
  • the voids 24,26 expose respective sections 34,37 of the reinforcement bars 22.
  • the column 10 is designed to replace three conventional and coaxially arranged upstanding columns as used in multi-storey building applications, whereby each column is designed to support the concrete floor of the level immediately above.
  • Each of the sections 28,30,32 of the column 10 is provided to replace a conventional support column.
  • the column 10 may be lifted to its upstanding position, with section 28 replacing (for example) a conventional support column provided on the ground floor, section 30 replacing a conventional support column on the first floor, and section 32 replacing a conventional support column on the second floor.
  • the lower end 12 of the column 10 includes a column securing means, which is integrated with a column height adjustment means.
  • the specific form of the integrated securing and height adjustment means is generally of the form provided in the embodiment illustrated in Figures 4 to 11.

  • the height adjustment means can then be used to manually alter the spacing between the lower end 12 of the column 10 and the footing F. Adjustment of the spacing between the lower end 12 and the footing F alters the effective overall height of the column 10 relative to the footing F. Specific details regarding the configuration and operation of the integrated securing and height adjustment means is provided in respect of Figures 4 to 11.

  • the void 24 exposes reinforcement bar section 34.
  • the void 24 and reinforcement bar section 34 provide a suitable location to connect a separate structure to the column 10.
  • the separate structure specifically (but not exclusively) contemplated for connection to the column 10 is a reinforced concrete beam for connecting and supporting the first level floor structure of a multi-storey building between two (or more) columns of the type illustrated by column 10.

  • the reinforced concrete beam would be constructed on site. Beam construction would initially involve creation of the beam's reinforcement structure, including longitudinally extending reinforcement bar(s). Either some or all of the beam's longitudinally extending reinforcement bar(s) can pass through the column, or the column and beam reinforcement may be connected if necessary or preferred. If the latter, one end of the beam's reinforcement bar(s) would be connected to the one or more of the bar sections 34. Connection may be by any suitable means including welding, or by configuring the end of the beam's reinforcement bar(s) in a hook shape for engaging about one or more of the bar sections 34.
  • the beam reinforcement bars may be arranged such that they extend substantially horizontally, with the other end of the beam's reinforcement bar(s) being connected to a second column (again, not illustrated).
