WO 01/28905 PCT/AUO0/01271 BRIEF DESCRIPTION OF THE DRAWINGS In order to facilitate a better understanding of the nature of the present invention several preferred 5 embodiments of an apparatus for fabricating a reinforcing element and a support spool about which the reinforcing element is wound will now be described, by way of example only, with reference to the accompanying drawings in which: Figure 1 is a schematic representation of an apparatus for fabricating a reinforcing element; Figures 2a to 2d are schematic representations of the apparatus of Figure 1 in operation; Figure 3 is another illustration of the apparatus of 15 Figure 1 in operation; Figures 4a to 4c depict various embodiments of means for receiving and effecting movement of the reinforcing members; and Figures 5a and 5b show several examples of a support 20 spool about which a reinforcing element can be wound.
DETAILED DESCRIPTION OF THE PREFFERRED EMBODIMENT As shown in Figure 1 there is an apparatus 10 for fabricating a reinforcing element 12. The reinforcing 25 element 12 includes a plurality of elongate load bearing reinforcing members such as 14A and 14B having' adjacent members connected by generally transversely oriented non-load bearing links of an adhesive tape 16A and 16B.
The apparatus 10 comprises means for receiving 18 each of the reinforcing members or bars such as 14B, and means for sequentially applying the adhesive tape 16A and 16B to the reinforcing bars such as 14A and 14B. Thus, the apparatus WO 01/28905 PCT/AU0O/O1271 forms the reinforcing element 12 with adjacent of the reinforcing bars such as 14A and 14B being interconnected by the adhesive tape 16A and 16B of the non-load bearing links.
In this embodiment the means for receiving 18 the reinforcing bars such as 14B is in the form of a bar transporter 22 which is longitudinally offset from the means for sequentially applying 20 the adhesive tape such 10 as 16A and 16B. The bar transporter 22 includes locating means in the form of a slot or recess which is shaped complementary to the sectional profile of one of the reinforcing members such as 14B.
The means for sequentially applying 20 the adhesive tape 16A and 16B in this particular example comprises a pair of pivoted rollers 24A and 24B disposed either side of a plane through which the reinforcing bars such as 14A and 14B are moved via the bar transporter 22. The pivoted 20 rollers 24A and 24B are each connected to a respective pivotal arm 26A and 26B which allows displacement of the rollers 24A and 24B relative to one another when one of the reinforcing bars such as 14A passes therebetween during application of the adhesive tape 16A and 16B. The 25 rollers 24A and 24B are biased toward one another via a torsion spring or the like (not shown) to assist in the application of the adhesive tape 16A and 16B to the reinforcing members such as 14A. Otherwise, the means for sequentially applying 20 the adhesive tape 16A and 16B 30 further comprises a pair of loading rollers 28A and 28B and idler or tension rollers 30A and 30B. The loading rollers 28A and 28B provide a mount for each of the rolls of tape 16A and 16B, respectively, whereas the idler or WO 01/28905 PCT/AU00/01271 tension rollers 30A and 30B are interposed between the respective pivot and load rollers such as 24A and 28A.
Figures 2a to 2d illustrate movement of one of the 5 reinforcing bars such as 14A through the pivot rollers 24A and 24B during application of the tape i6A and 16B. In this example the reinforcing bar 14A is sandwiched between the opposing pair of adhesive tapes 16A and 16B which thus provide the non-load bearing link oriented generally 10 transverse to the reinforcing bar 14A. Figures 2a to 2d depict movement of one of the reinforcing bars 14A through the means for applying 2 0 the adhesive tape 16A and 16B and indexing of the bar 14A relative to the pivoted rollers 24A and 24B and the adjacent reinforcing bar 14B. 15 Figure 2d shows a pair of knives 32A and 32B which together cooperate so as to cut or shear the tape 16A and 16B once the reinforcing element 12 has been fabricated. As further illustrated in Figure 3 the reinforcing bars such as 14A and 14B are spaced a predetermined distance 20 and the tape 16A and 16B is cut so as to provide a similar start or index position for the first reinforcing bar such as 14A' of the next reinforcing element such as 12'.
Figures 4a to 4c illustrate various examples of the means 25 for receiving 18 the reinforcing members such as 14A together with means for effecting movement of the reinforcing members relative to the adhesive tape 16A and 16B. In Figure 4a the means for receiving and effecting movement of the reinforcing members together comprises a 30 rotary disc having locating means in the form of a series of recesses formed at predetermined spacings about its periphery. The recesses 38 are each configured to retain one of the reinforcing bars such as 14A and accordingly WO 01/28905 PCT/AU00/01271 are formed as slots shaped complementary to the sectional profile of one of the reinforcing bars. The rotary disc 36 is generally one of several discs which are longitudinally offset from the means for sequentially 5 applying 20 the tape 16A and 16B. Similarly, the means for sequentially applying 20 the tape 16A and 16B is generally one of a series of spaced pivoted rollers 24A and 24B which provide a series of non-load bearing links in the reinforcing element 12.
Figure 4b illustrates an alternative embodiment of the means for receiving and effecting movement of the reinforcing bars such as 14A. In this example there is provided a continuous belt having locating means provided 15 about its outer periphery for receipt of the reinforcing bars such as 14A. The continuous belt 40 is wrapped about a drive and an idler drum or pulley 42 or 44, respectively. A rotary drive mechanism (not shown) is operatively coupled to the drive drum or pulley 42, or in 20 the previous embodiment the rotary disc 36, to effect rotation . or movement of the reinforcing bars such as 14A relative to the means for applying 20 the tape 16A and 16B.
In an alternative embodiment the means for receiving 18 at least one of the reinforcing members such as 14A includes a reciprocating member or arm 50 having locating means in the form of a recess 52 formed at its outermost end which is configured to receive and retain one of the reinforcing 30 bars such as 14A. The reciprocating arm 50 slides the reinforcing bar such as 14A between the pivot rollers 24A and 24B a predetermined distance and then retracts for receipt of the next reinforcing bar such as 14B to which WO 01/28905 PCT/AU00/01271 the adhesive tape 16A and 16B is to be applied. Thus, the reinforcing element 12 is progressively formed with adjacent of the reinforcing bars such as 14A and 14B being interconnected by the adhesive tape which forms the non-5 load bearing links.
The specific construction. of one . example of the reinforcing element 12 is disclosed in the specification of Australian complete patent application No. 97051/98 10 which is included herein by way of reference. The non-load bearing links are formed by two strips of fibre-reinforced pressure sensitive tape such as 16A and 16B. The pressure-sensitive tape of this embodiment has high adhesion strength both to itself and to the reinforcing 15 bars such as 14A and 14B which in this example are steel reinforcing bars. It is preferable that the material from which the pressure sensitive tape is constructed has a density which is lower than that of concrete and that is materially compatible with steel and concrete.
According to another aspect of the invention there is provided . a support spool such as 100 as illustrated in Figures 5a and 5b. The support spool 100 of Figure 5a is designed to have a reinforcing element 12 such as that 25 described above wound about it for compact storage and/or transportation purposes. The support spool is adapted to be rotated via a collapsible mandrel 102 which is configured to releasably engage the support spool 100 which can thus be rotated for loading of the reinforcing 30 element 12. The support spool 100 of Figure 5a is formed as a helical or spiral member 104 about which the reinforcing element is wound. The reinforcing bars such as 14A of the reinforcing element 12 are thus oriented generally transverse to the helical or spiral member 104. In the alternative example of Figures 5b the support spool 1000 includes a pair of axially spaced ring members 1002 and 1004 interconnected via four (4) axially aligned bars 5 1006A to 1006D. In this embodiment the reinforcing bars such as 14A of the reinforcing element 12 are wrapped about the ring members 1002 and 1004 with the non-load bearing links of adhesive tape being wound about the circumferential bars 1006A to 1006D. In both examples of 10 the support spool 100 and 1000 the collapsible mandrel 102 releasably engages an inner-facing surface of the spool 100 or 1000. The collapsible mandrel 102 is shown schematically in solid and broken outline in Figures 5a and 5b.
The spools 100 or 1000 provide a temporary support for the reinforcing element 12 during transportation to, for example, a building site. The support spool 100 or 1000 is preferably provided downstream of the apparatus 10 for 20 fabricating the reinforcing element 12. Generally, the reinforcing element 12 or bundle of reinforcing bars such as 14A are of a total mass which can be lifted by the mechanised lifting and handling equipment used for the purpose of lifting, transporting and placing. These 25 bundles or rolls of reinforcing elements such as 12 allow the individual reinforcing bars such as 14A to be positioned in their correct relative lateral position prior to the pouring and setting of concrete in a building element such as a floor slab.
In order to further describe the apparatus 10 for fabricating a reinforcing element such as 12 its operation will now be outlined: WO 01/28905 PCT/AU00/01271 (i) reinforcing bars such as 14A to 14C are fed to the entry point of the apparatus, this being effected either manually or via a conveyor; (ii) the reinforcing bars such as 14A are then fed to 5 the means for receiving 18 at least one of the bars such as 14A; (iii) the adhesive tape is fed between the pivot rollers 24A and 24B prior to the entry of the reinforcing bar 14A which traverses through its first indexing point; (iv) the reinforcing bar such as 14A and adjacent bars such as 14B are then indexed forward and sandwiched between the adhesive tape, see for example Figures 2a to 2d; (v) once the last bar in the sequence is taped the 15 reinforcing tape is cut to provide a similar starting position for the next reinforcing element or bundle as shown in Figure 3; (vi) the "train" of taped reinforcing bars is then progressed forward and propelled onto a supporting table for consolidation of the bundle or it is wound around a support spool such as that described in the context of Figures 5a and 5b; and (vii) the reinforcing element or bundle is unrolled from the support spool at a building site.
Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. For example, the apparatus for fabricating the reinforcing 30 element may "jig" the reinforcing bars which are then held stationary with application of the adhesive tape across the reinforcing bars. In this example the adhesive tape may simply be manually applied across the reinforcing bars which are held stationary.
All such variations and modifications are to be considered 5 within the ambit of the present invention the nature of which is to be determined from the foregoing description.
In the claims which follow and in the preceding summary of the invention, except where the context requires otherwise 10 due to express language or necessary implication, the word "comprising" is used in the sense of "including", that is the features specified may be associated with further features in various embodiments of the invention.
