Definitions

  • the invention relates to a device and method for fastening elongated members together. More particularly the invention is adapted for use in fastening steel reinforcing rods together.
  • steel reinforcing rods are manually tied together by wire.
  • the rods are usually at right angles to one another and are to be held in place so that concrete poured around them has a predetermined reinforcement profile.
  • the most common method of tying the wire about the rods involves using a pair of wire cutters.
  • the wire is generally looped to encircle the two bars diagonally, the ends twisted together twice and the excess wire is cut off.
  • the invention proposes a device for and method of fastening which substantially reduces time and labour requirements and increases the reliability and uniformity of the fastening of elongated members .
  • an apparatus to fasten together at least two elongated members comprising means adapted to be moved into contact with a staple and move the staple in a predetermined direction and deflecting means to deform at least a portion of the staple about the elongated members.
  • the apparatus further comprises a leg extending between the impact means and the deflecting means.
  • this leg may be adjustable.
  • the deflecting means comprises a foot having at least one groove for directing the portion of the staple about the elongated members.
  • the foot may
  • EET include at least one removable insert, the insert having the at least one groove located therein.
  • the apparatus In operation, the apparatus is located about the elongated members, the foot or feet are positioned underneath the lower transverse member and straddle the upper rod.
  • the impact means When in position, the impact means is actuated, typically by a trigger mounted on a handle, driving the substantially U-shaped staple into grooves provided in the feet.
  • the foot or feet deflect and bend the staple legs about the lower rod.
  • the apparatus further comprises a detachable magazine housing which is adapted to receive at least one staple and direct the staple in a predetermined position for movement by the impact means.
  • the foot or feet are provided with a hardened insert e. g. of steel.
  • a hardened insert e. g. of steel.
  • the insert or inserts are bolted into the foot.
  • the appropriate groove can be selected to match the rods to be tied without always requiring a change of adjustable legs or feet -
  • an apparatus to fasten together at least two elongated members comprising:
  • the impact means being adapted to move a staple in a predetermined direction towards and against the deflecting means to deform at least a portion of the staple about the elongated members.
  • the apparatus is typically positioned with respect to the members so the staple arm will bridge across members to be tied.
  • the groove forces the staple leg to envelop the members thereby fastening them sufficiently rigidly to prevent premature disengagement.
  • a method of fastening a staple having two legs about at least two elongated members comprising the steps of:
  • the apparatus may be adjustable in either or both the length of the legs or the mutual separation of the feet.
  • the size of the foot or feet will o depend on the size of the lower rod used.
  • Various sizes and combinations of rod may be fastened and all that is necessary is for the user to select a foot with the correct groove size and curvature and a ram with the appropriately shaped impact means.
  • This adjustment is achieved by the foot and leg having pluralities of -_- alignable apertures through which the bolts are placed. Alternatively, this adjustment is achieved by a series of interlocking teeth and grooves secured with bolts.

  • Piston K may be operated pneumatically by connection to a pressure source.
  • the chamber A may be of the combustion type, e. g. ignition of combustible gases (e. g. butane) to force the piston K downward or alternatively, operate under pressurised air.
  • the mutually perpendicular rods X and Y are located about adjustable legs C and feet J.
  • the adjustable legs C are secured onto frame B using shear bolt D. Adjustment in the length of the legs C is achieved by repositioning shear bolt D in the appropriate holes in the frame B and the legs C.

Abstract

Sont décrits un procédé et un appareil pour assembler des éléments allongés. L'appareil comprend une chambre (A) qui abrite un piston (K) boulonné à un plongeur (M) dont l'extrémité inférieure est conformée de manière à venir frapper sur l'agrafe (N1) logée dans le porte-magasin (H) en s'alignant avec la plaque de guidage (J). Des barres mutuellement perpendiculaires (X et Y) sont situées autour de jambages (C) et de pieds (J) réglables. Des jambages (C) sont réglés à l'aide d'une pluralité d'éléments d'écartement (F) et sont assujettis sur le cadre (B) par le boulon de cisaillement (D), le cadre (B) étant assujetti à la chambre (A) par serrage du boulon de cisaillement (D). L'engagement de la gâchette (I) amène le piston (K) à obliger le plongeur (M) à venir frapper sur l'agrafe (N1). Cette dernière s'abaisse et sa ou ses branches se courbent en arc grâce aux gorges (L) pour déformer au moins une partie de l'agrafe autour des éléments allongés.
