description

Connecting bow baskets, connecting baskets or bow baskets for connecting reinforcements are terms used in concrete or reinforced concrete construction. In the prior art is a connecting bow basket in the document DE 3210680 described. In this case, a plurality of longitudinal bars are connected to a plurality of U-shaped bent and a cross bar having brackets, wherein each one leg of the strap are longitudinally free. The connecting bar baskets are preferably used in building transitions from floor or ceiling elements to wall elements. In practice, it has been shown that the free leg ends grant a certain degree of flexibility during assembly, but at the same time there is a considerable risk of injury due to the length of the leg without legs.

In the document EP 0495135 In order to overcome this risk of injury, it is proposed to arrange one of the longitudinal bars undetachably on one limb, while the other limb-free limbs are connected to a detachable longitudinal bar, which should be easily removable. One of the disadvantages of this device is that the removal of detachable longitudinal bars is associated with considerable additional expenditure and leads to additional costs, especially in the cost-sensitive construction industry.

There are also connecting bow baskets known in which the problem described the risk of injury in longitudinally stable legs is to be repaired by the ends of the free legs are provided with a U-shaped hook. One of the disadvantages of this embodiment of the clip-on baskets is that the baskets interlock with one another by the bent ends both during stacking and unstacking of the baskets before or after transport. Furthermore, other reinforcing steel connecting reinforcements caught in their positioning and laying in the final hook. In addition, it is disadvantageous that the tail of a concrete vibrator can get caught in the built-in terminal bow baskets. A further disadvantage is that in the production of hook-mounted connecting bracket baskets with respect to the connecting bracket baskets without hooks an additional step is necessary.

Out CH 675442 A5 a connecting bow basket for components made of reinforced concrete is known, which has a plurality of mutually spaced U-shaped bracket, which are connected to extending perpendicular to the brackets bars, wherein the connecting rods are arranged exclusively at or near the free ends of both legs of the bracket. In this case, two or more connecting rods are provided on each side of the bracket. One of the disadvantages of the invention is that the stirrups are poorly stabilized, so that transportation and handling during assembly of a basket are made more difficult.

Out GB 1267474 A a stirrup reinforcement for concrete beam-shaped support is known, wherein the stirrup arm is formed from two assembled stirrup baskets, so that the stirrup arm can be adapted to different support heights. Each hanger basket has at least one continuous longitudinal bar at each end of the free legs of the stirrups, which are intended to serve to stiffen the basket. Subsequently, in the upper part of the stirrup reinforcement bars could, for example, be attached by Verrödelung.

Out DE 20 2005 013 048 U1 a component for shear reinforcement of concrete components is known, which consists of a plurality of shear bolts designed as a head bolt, wherein the U-shaped head bolts have terminal bolt heads. The U-shaped design of the head bolt would allow over closed shear reinforcement stirrups a subsequent insertion of longitudinal reinforcement bars. It is proposed to form the U-shaped head bolts of welded parts.

Out CH 681096 A5 is a reinforcing basket for floor-wall connection is known, which consists of a plurality of U-shaped bent bracket, wherein in each case a vertically arranged bracket is welded to a horizontally arranged bracket at an angle of 90 degrees, wherein between the legs of the vertically arranged bracket a rod for Fastening a joint strip is arranged, wherein a number of connected at an angle of 90 degrees bow at regular intervals by means of longitudinal rods firmly together are connected, wherein the vertical bracket are longitudinally free. One of the disadvantages of the invention is that the longitudinally free ends of the vertical stirrups pose a risk of injury during handling. Furthermore, the free ends are suitable for transporting the reinforcing basket to get caught or jammed.

It is therefore an object of the present invention to propose a connecting bow basket which does not have the disadvantages of the prior art. In particular, the connecting bow basket should be inexpensive to produce and enable safe and efficient installation on construction sites.

The object of the invention is achieved by a connecting bow basket with a plurality of spaced apart and parallel to each other, U-shaped bent, two legs and a cross bar having brackets, which are connected to at least three mutually parallel spaced longitudinal bars, wherein a first and a second longitudinal bar is connected to the one legs of the bracket, wherein a third longitudinal bar is connected to the respective other legs of the bracket, wherein the first and the third longitudinal bar are each arranged in the region of a corresponding free leg end of a bracket.

One of the advantages of the invention is that there are no protruding or protruding rods of the connecting rod cage, which could constitute a risk of injury. As a result, the handling and assembly of the inventive connecting bracket baskets can be done safely and accident hazards are reduced.

One of the advantages of the invention is that when the second longitudinal bar is arranged at approximately half the leg length, on the one hand, a stable connecting bow basket can be realized, so that the bars are held together sufficiently rigidly. On the other hand, this arrangement allows the connecting bar basket to be flexible can be used, for example. When inserting the basket in the mesh of a reinforcing mesh, in other, consisting of individual reinforcing bars reinforcements or in other ironing baskets.

In another embodiment variant of the invention, the second longitudinal bar is arranged in the free end of the leg close to the third of the entire length L of the leg.

In one embodiment of the invention, the first and the third longitudinal bar of the connecting bar basket are each spaced at a distance h from the corresponding free leg ends of a stirrup. One of the advantages of the invention is that by this arrangement, the requirements for safety in construction are met. Since there are no protruding or protruding free ends of temples of a yoke cage, the risk of injury is minimal.

In another embodiment variant of the invention, the first and the third longitudinal bar of the connecting bar basket are respectively arranged on the corresponding free leg end of a stirrup. One of the advantages of the invention is that the longitudinal bars can also be connected to the end faces of the leg ends of the bracket, for example by welding or gluing.

In a further embodiment variant of the invention, the second longitudinal bar of the connecting bar basket is arranged between the free leg end of a stirrup and the leg end connected to the transverse bar. Advantageously, different needs can be met or demanded the follower bow basket can be fulfilled by arranging the second longitudinal bar closer to the crosspiece or closer to the free end of a respective leg. Thus, on the one hand a connecting bracket basket can be realized, which has sufficient stability, which is particularly characterized when handling and laying. On the other hand, the second longitudinal bar can be arranged so that the flexibility in laying the basket and connecting with other reinforcing elements is granted.
