Spacer for a mat-shaped concrete reinforcement

The innovation concerns a spacer for a
mat-shaped concrete reinforcement that is firmly bonded to the mat

Various proposals have been made for a distance holder made to ensure that the loading

The reinforcement mat can be fixed precisely and safely at the calculated altitude. The known spacers are often made of plastic, sheet metal, wires, etc. They are designed as a special construction part, which has the even part is that when laying the mats with their built-in an additional working - is beit required.

There are also spacers that are already used during manufacture inserted into the mat. These are designed as rings that can be moved on the longitudinal or Cross bars of the mat. Such displaceable spacers have the disadvantage that they are during laying need to be aligned so that they come in the right place. Make all of these known spacers special construction parts that have no influence on the load-bearing capacity of the reinforcement.

The task of the innovation is to create a spacer that is permanently installed at the same time as the reinforcement mat is manufactured and that forms part of the reinforcement, ie influences the load-bearing capacity of the reinforcement «

To solve this problem, a spacer of the type mentioned is proposed, which thereby is characterized in that it runs parallel to the transverse or longitudinal bars, the load-bearing capacity the reinforcement influencing rod is formed, the ends of which as distance-determining elements are bent at an angle.

The diameter of the spacer is advantageous equal to that of the other bars of the reinforcement mesh. The rod forming the spacer extends over several Cross or longitudinal bars and is welded to them at the crossing points.

The drawing is an exemplary form of training recognizable.

The mat-shaped concrete reinforcement 1 consists in itself known manner from longitudinal bars 2 and cross bars 3j which are arranged at a distance from one another and in a grid-like manner are welded together at the crossing points.

At one or more places, parallel to the transverse or longitudinal bars, additional bars 4 are attached

their ends 5 are bent at an angle, the bent ends determining the distance. These bars k are also with the transverse or longitudinal bars, which
cover them, welded at the crossing points. The desired distance can be determined by cutting the bent ends 5 to length or by the bending angle 6. The same rod material is advantageously used to produce the spacers as for the construction of the rest of the reinforcement mat. The spacer can already be permanently installed during the manufacture of the reinforcement mat, so that no additional work is required on the construction site.
