Definitions

  • the present invention relates to a method for production of reinforcement for concrete members, preferably concrete piles, according to the preamble of claim 1, reinforcement for concrete members according to the preamble of claim 5 and a strut member intended for such reinforcement according to the preamble of claim 7.
  • piles play an important role in connection with ground strengthening.
  • the piles normally comprise an inner reinforcement of steel and a concrete body cast around the reinforcement, in most cases with some form of end strengthening.
  • a known technique for producing such piles comprises elongating a steel wire in the form of a compact coil to an extented coil, placing the elongated coil on a height-adjustable support and, by means of a feeding device, inserting reinforcing iron bars into the extended coil on the support.
  • the support is height-adjustable and in a first phase two reinforcing bars or two groups of such bars are fed in and placed mutually spaced apart in the horizontal plane. Thereafter these bars are affixed to the elongated steel wire coil by means of a binding operation which can comprise binding at mutually spaced locations, for example in the order of one meter apart.
  • This attachment can be seen as maintaining the bars by means of binding wires in which the bars quite simply hang.
  • the binding is a totally manual operation which requires great speed and which, because of its monotony, becomes extremely tiring in the long run.
  • a method of producing reinforcement for concrete members is known from FR-E-19 585 in which reinforcing bars are initially affixed to the interior of an outer coil before a second coil is introduced within the extended coil which, when relaxed, holds the reinforcing bars against the outer coil.
  • GB-A-21,851 discloses a reinforced construction in which reinforcing rods are held in spaced relationship by means of specially formed wire ties. Struts may be used to assist the action of the ties in stiffening the reinforcing rods.
  • FR-A-2 146 170 discloses a distance element in the form of a cross which is used to maintain reinforcing. rods in spaced relationship.
  • the invention accordingly provides a method for producing reinforcement for concrete members, preferably concrete piles, having the features of claim 1.
  • the invention also provides reinforcement for concrete members, preferably concrete piles, having the features of claim 5.
  • the invention also provides a strut member intended for reinforcement and having the features of claim 7.
  • the invention relates also to a concrete member, preferably a concrete pile, provided with the said reinforcement.
  • Figure reference numeral 10 in Fig. 1 refers to a wound steel wire compact coil and figure reference numeral 10' refers to the same steel wire but elongated to an extended coil 10'.
  • This coil 10' can have a length of for example several meters, say four to eight meters, and is placed on height-adjustable supports 11,12 and 13. Holders 14,15 and 16 on these supports fix the coil 10' in its extended condition and thus counteract the spring force therein.
  • FIGS. 17,18 and 19 indicate that respective supports are height-adjustable.
  • a first vertical position of the supports a first set of reinforcing bars 20 is fed in between a pair of rollers 21,22 of which one is a driven roller.
  • Individual reinforcing bars 20 or a plurality thereof, for example two, are laid in the first vertical position such that they extend along the whole coil 10' and have a certain mutual spacing in the horizontal plane.
  • the supports 11,12 and 13 are lowered a little, sufficiently for the subsequent batch of reinforcing bars 20 to be able to be positioned, so that they are placed with mutual spacing in the horizontal plane at a level substantially in contact with the inside of the coil 10'.
  • the reinforcing bars With the reinforcing bars and the supports in this position, the reinforcing bars are temporarily fixed in their positions by means of spacing members of the type shown in Fig. 5.
  • the spacing members can be placed not only diagonally, but also along the sides of the imaginary rectangle.
  • Fig. 4 shows four reinforcing bars 20 placed so that the four-sided cross-section 23 shown with dashed lines is formed.
  • the broken lines 24,25 indicate that a section of the elongated coil 10' somewhere between its ends is being considered, which ends, as mentioned earlier, are temporarily fixed by means of spacing members of the type shown in Fig. 5, or shorter such members placed along the sides of the imaginary rectangle.
  • spacing members of the type shown in Fig. 5, or shorter such members placed along the sides of the imaginary rectangle.
  • the tensioning- or strut members 26 are shown in the form of elongated struts with a notch 27 symmetrically located relative to the strut in the one end and a notch 28 turned through 90° with respect to the notch 27.
  • the notch 27 is placed over its corresponding reinforcing bar and, by means of for example a rubber mallet, the notch 28 is banged into place on its reinforcing bar 20.
  • strut or tensioning member is introduced at a suitable spacing from the former, for example in the order of one meter.
  • the latter strut 26 is oriented so that it is in a different diagonal direction in relation to the first strut.
  • the struts 26 are used as means for pressing the reinforcing bars outwards against the inside of the coil, a robust and easily reproducable arrangement for effecting stability of the pile reinforcement is provided, at the same time that this is achieved with a number of simple manual operations.
  • the need for the binding wires along with their unpredictable retaining ability is accordingly avoided and there is further no need for any welding with the troublesome weld fumes emitted therefrom.
  • Fig. 6 it is shown how three reinforcing bars 20 in cross-section are located by means of another type of tensioning-strut arrangement 26.
  • a tensioning-strut arrangement 26b is given in Fig. 7 which cooperates with all four sets of reinforcing bars 20.
  • Fig. 8 shows another type of four-cornered supporting tensioning- or strut arrangement in the form of a four-sided frame.
