Definitions

  • the present invention relates to an apparatus and a method for the production of concrete beams or the like.
  • an apparatus for use in the production of concrete beams comprising two rows of at least two spaced-apart, generally vertically extending supports, with at least one elongate support member extending generally horizontally between aligned supports of the two rows, said support members lying in at least one common plane, elongate mould members each having an L-shaped transverse cross-­section, resting on the support members in any one said common plane, said mould members abutting each other and, together with a closure member, forming a series of elongate channels having a generally U-shaped transverse cross-section.
  • end stop members made of metal, wood or any other suitable material are used to close the end regions of the adjacent channels.
  • a third end stop member is slotted and engageable over the channels at any position along the length of the channels.
  • end stop members also preferably have apertures/slots for holding reinforcement bars in position whilst the concrete is poured and it hardens.
  • a number of parallel spaced apart support members each in the form of a steel bar, extend horizontally between each pair of aligned supports, as per the rungs of a ladder.
  • the vertical supports are preferably fixedly held in position by being embedded in concrete. Alternatively, they may be bolted to a concrete base or form part of a steel frame which may be dismantled if required.
  • the apparatus may be manually constructed on site, each component part of the apparatus being light enough to be lifted without the aid of lifting tackle.
  • a number of beams can then be simultaneously produced on each horizontal set of so-called rungs. In this way the damage which can and does at present occur during transit and off-loading, can be avoided.
  • the L-shaped mould members it is relatively easy to separate the concrete beams without the usual damage.
  • the vertical supports each preferably have an H-shaped transverse cross-section, with the steel bars forming the support members, engaging through holes in the flanges of the H-shape.
  • the end regions of the steel bars are preferably threaded and nuts secure the bars in position.
  • nuts are provided at each end region of each bar, on both sides of the flange of a vertical support to thus strengthen the structure and maintain the correct spacing of the aligned supports.
  • the closure member is an elongate planar member which is merely positioned against said one vertical support, the closure member merely converting the L-shape of the outer mould member to a U-shape.
  • the closure member may take the form of a U-shaped channel section, which is located between two sets of oppositely facing L-shaped mould members.
  • the distance between the vertical supports in a row is advantageously two metres, with the distance between the rows being 1.5 metres. This is convenient for the spreading and levelling of the concrete.
  • the dimensions can, of course, be selected as desired.
  • the outermost mould members or mould member and closure member may have an increased vertical dimension as compared to the other mould members, to thus retain poured concrete on the adjacent channel arrangement whilst the concrete is being poured and smoothed into the moulds.
  • the concrete is preferably trowelled smooth using a suitable trowel, and as one channel arrangement is filled it is preferably covered by, for example, a sheet of wood, to prevent it being subject to drips etc., from an upper channel arrangement which is subsequently filled.
  • the locking nuts When the concrete has hardened, the locking nuts can be released and the concrete beams can be manually removed, the L-shaped mould members being relatively easy to release without causing damage to the beams.
  • a method of forming concrete beams comprising the steps of laying a number of elongate mould members on a number of horizontal support members, each mould member having an L-shaped transverse cross-section, securing the mould members in abutting relationship, to thus form a number of parallel U-shaped channels, pouring concrete into the channels, and releasing the mould members from their abutting relationship when the concrete has hardened.
  • a preferred embodiment of the present invention comprises two parallel rows 1,3 of equi-spaced apart elongate, vertical supports 5.
  • the vertical supports 5 of one row 1 are each aligned with a corresponding support 5 of the other row 3.
  • the vertical supports 5 are secured in a concrete base and support members in the form of elongate steel bars 7 extend between each pair of aligned supports 5, these steel bars 7 being spaced apart as per rungs of a ladder, with corresponding rungs of the aligned pairs of supports being located in a common horizontal plane.
  • the supports 5 can be bolted to a concrete base or a steel base framework.
  • each vertical support 5 has an H-shaped transverse cross-section and a steel bar support member 7 extends between corresponding flanges 9 of the aligned supports 5, and a further steel bar support member 7 extends between the further flanges 11 of the aligned supports 5 at each rung level.
  • These support members 7 at each rung level are therefore in the same horizontal plane and parallel to each other.
  • the end regions of the support members 7 are threaded and engage through aligned apertures in the corresponding flanges 9,11 of the aligned supports 5. These threaded end regions then receive nuts 13 to secure the bars 7 to the supports 5, a nut being located on both sides of each flange.
  • Elongate mould members 17, each having an L-shaped transverse cross-section are located on one or more sets of horizontally aligned rungs, i.e. support members 7, of the aligned pairs of supports 5, and they are all located in abutting relationship with the same orientation, to thus form a number of U-shaped cross-section elongate channels 19.
  • the left-hand end mould member is closed to form a U-shaped channel 19, by an elongate, planar closure member 21 which engages against the supports 5 of row 1.
  • this planar closure member 21 is comprised of an elongate, generally rectangular, L-shaped cross-section member 21a and an elongate, generally rectangular wooden member 21b with a recess 21c provided for location over nuts 13. This construction is selected to reduce weight and ensure that the closure member can be easily lifted by hand.
  • a locking nut 23 is provided in a threaded region of each support member 7, the locking nuts 23 merely being tightened against the mould member 17 at the right-hand end, as viewed in Figs. 2 and 3.
  • end stop members 25 and 27 made of metal.
  • the end stop members can be made of wood or any other suitable material.
  • End stop members 25 and 27 are secured to the webs of the H-shaped supports 5 by bolts 15.
  • End stop members 25 and 27 are each elongate planar members and sit on the horizontal arms of the respective mould members 17, the end regions 16 of the horizontal arms of the mould members 17 being so exposed by virtue of the vertical arms of the respective mould members 17, having a reduced axial length as compared to said horizontal arms. In this way a positive seal is attained at each end.
  • the upper edge of the end stop member is also provided with slots 31 which serve to position and hold any reinforcement bars whilst the concrete is hardening.
  • a reduced length beam may be required.
  • a third end stop member 28 is used.
  • This end stop member 28 is again an elongate, planar member, made of metal, with slots 33 formed in its lower edge.
  • end stop member 28 can be made of wood or any other suitable material. This end stop member 28 can thus engage over the mould members at any position along their length, with the vertical arms of the L-shaped mould members engaging in slots 33.
  • slots 30 are provided in end stop member 28 for use in supporting reinforcement bars.
  • slots 30 which extend from the upper edge of stop member 28 as illustrated in Fig.5, can be replaced by holes for the support of reinforcement bars whilst the concrete is being poured into the moulds and is curing.
  • Stop members 28 can be located at any desired position along the length of the mould members and held in position by clamps or any other suitable means.
  • the mould members 17 and end stop members 25,27 are located on the lowermost rungs of the supports and concrete is poured into the channels 19. Further mould members 17 can then be located on upper rungs and filled with concrete. To prevent damage to the finished concrete in the lower channel assemblies, the channels are preferably covered by, for example, sheets of plywood. When the concrete has hardened, the locking nuts 23 are slackened and the beams can be withdrawn manually or otherwise, it being a simple matter to free the L-shaped mould members 17.
  • both the closure member 21 and the L-shaped mould member at the right-hand side of Fig.2 can have an enlarged vertical dimension so that the concrete stays within the channel assembly whilst it is trowelled to the desired depth in the adjacent channels.
  • the L-shaped mould members 17 are divided into two sets of oppositely directed mould members on each horizontal set of rungs, with the closure member taking the form of an elongate, U-shaped channel member 35.
  • the present invention thus provides a simple apparatus and method for the on-site production of concrete beams, the apparatus being man-handlable without the essential need for lifting gear.
