Definitions

  • the invention relates to a reinforcement anchor with a reinforcement holder for the shear reinforcement of reinforced concrete slabs or beams, wherein the reinforcement anchor has an elongated anchor shaft extending perpendicular to the plate or beam plane in the installed state, which is provided at least at one end with a disk-shaped anchor head.
  • Such reinforcement anchors serve to absorb the shear stresses occurring in reinforced concrete slabs or beams.
  • These reinforcement layers consist of reinforcement bars running parallel to a slab or beam plane, with which the reinforcement anchors must be connected in a form-fitting manner.
  • the disc-shaped anchor heads of the reinforcement anchors grip around the pressure reinforcement layer and around the bending reinforcement layer of the reinforced concrete slab. It is important that this spatial assignment of the reinforcement anchors and the reinforcement layers must also be maintained when the concrete is being placed, otherwise the reinforcement effect will not be sufficient.
  • reinforcement cages or similar spacers between the two reinforcement layers As a result, the one reinforcement layer is held at a distance such that the anchor heads of the reinforcement anchors protrude beyond this reinforcement layer.
  • the object of the invention is therefore to provide a reinforcement anchor with a reinforcement holder of the type mentioned at the outset, which enables a secure and positive connection of the reinforcement anchors to the reinforcement bars in a simple operation.
  • the anchor head has a holding hole in its end face and that the reinforcement holder is a resilient wire bracket which lies with an upper bracket leg on the end face of the anchor head and engages with a retaining projection in the retaining hole and hook-shaped with a lateral bracket leg encompasses a reinforcing bar lying on the inner surface of the anchor head and on the anchor shaft.
  • the resilient wire bracket which snaps into place during the manufacture of the reinforcement with a simple and rapid movement of the anchor head and the associated reinforcement bar, resiliently presses the reinforcement bar into the angle formed between the inner surface of the anchor head and the anchor shaft. There the reinforcement bar is held securely even during concreting.
  • the anchor head lies with its inner surface directly on the reinforcing bar, which ensures direct positive force transmission.
  • the holding bore is preferably arranged centrally in the end face of the anchor head. This ensures that the reinforcement holder can extend to any side.
  • the invention is based on one
  • Fig. 1 is a reinforcement anchor for the shear reinforcement of reinforced concrete slabs with two reinforcement bars from two separate reinforcement layers and
  • Fig. 2 shows the reinforcement holder used in the arrangement according to Fig. 1.
  • the reinforcement anchor 1 shown in FIG. 1 has an elongated anchor shaft 2 which, in the installed state, extends perpendicular to the plate plane of the reinforced concrete plate (not shown) or a beam to be reinforced.
  • the cylindrical, rod-shaped anchor shaft 2 has a disk-shaped anchor head 3, which is preferably upset in one piece.
  • the anchor head 3 is circular.
  • a reinforcement bar 4 of a first reinforcement layer of the reinforced concrete slab running parallel to the plane of the plate rests on the inside of the lower anchor head 3 and on the anchor shaft 2.
  • a reinforcement bar 5 of a second reinforcement layer of the reinforced concrete slab lies against the inside 3a of the upper anchor head 3 and against the anchor shaft 2.
  • the reinforcement bar 5 is held in this position by a reinforcement holder 6 consisting of a resilient wire bracket.
  • the one, upper stirrup leg 7 of the reinforcement holder 6 lies on the upper end face 3b of the anchor head 3 and runs approximately radially there.
  • a substantially U-shaped tab 8 is formed on the upper bracket leg 7 and engages as a holding projection in a holding hole 9 in the end face 3 b of the anchor head 3.
  • the holding hole 9 is arranged centrally in the end face 3b.
  • the U-shaped tab 8 is adjoined by an end section 10 of the stirrup leg 7 which bears against the end face 3b of the anchor head 3.
  • the wire bracket forming the reinforcement holder 6 is bent downward and forms a lateral bracket leg 11 which engages around the reinforcement bar 5 and holds it in position.
  • the side bracket leg 11 has an arcuate end section 12, the radius of which is approximately equal to the radius of the encompassing reinforcing bar 5.
  • This circular arc-shaped end section only partially surrounds the reinforcing bar 5; the end section preferably extends over a circular arc from approximately 130 ° to approximately 160 °.
  • the reinforcement bar 4 of the other reinforcement layer can be fastened in a corresponding manner with a reinforcement holder 6, as is shown individually in FIG. 2.
  • the reinforcement anchor (6) for the shear reinforcement of reinforced concrete slabs or beams, the reinforcement anchor (6) having an elongated anchor shaft (2) extending perpendicular to a plate plane in the installed state, which has at least one end with a disc-shaped anchor head ( 3), characterized in that the anchor head (3) has a holding bore (9) in its end face (3b) and that the reinforcement holder (6) is a resilient wire bracket which is connected to the end face (7) by an upper bracket leg (7). 3b) of the anchor head (3) and engages with a retaining projection (8) in the retaining bore (9) and with a side bracket leg (11) hook-like one on the inner surface (3a) of the anchor head (3) and on the anchor shaft (2) Reinforcing bar (5).
  • Reinforcement anchor with reinforcement holder according to claim 1, characterized in that the holding bore (9) is arranged centrally in the end face (3b) of the anchor head (3).
  • Reinforcement anchor with reinforcement holder according to claim 1, characterized in that the holding projection is formed by a substantially U-shaped tab (8) of the upper bracket leg (7).

Abstract

Un ancrage (9) pour le ferraillage relevé de dalles ou de poutres en béton armé comprend une tige allongée (2) pourvue à ses extrémités de têtes d'ancrage (3) en forme de disque. Une barre d'armature (5) faisant partie d'une nappe d'armature de la dalle ou de la poutre en béton armé est retenue par un arceau élastique en fil métallique qui forme un support (6) de l'armature. Une branche supérieure (7) de l'arceau comprend une protubérance de retenue (8) qui pénètre dans un creux de retenue (9) ménagé dans la face frontale (3b) de la tête d'ancrage (3). Une branche latérale (3b) de l'arceau qui forme le support (6) de l'armature entoure la barre d'armature (5) qui repose sur la surface intérieure (3a) de la tête d'ancrage (3) et sur la tige d'ancrage (2).
