So that the prescribed coverage of the If iron reinforcement is ensured by concrete, so-called spacers are placed between the reinforcement and the formwork. Should on the concrete part, e.g. on an apartment ceiling or wall a so-called Second shell can be attached for the purpose of sound and heat insulation, or installations etc. are attached, then special dowels set in concrete, or other types of fastening means are used.

The present invention is a union of spacer and dowel · This eliminates the need for spacers and dowels separately to be attached, which saves material and working time.

The new spacer dowels are firmly pressed onto the formwork by the irmioruagsafeabe on them. Through this the otherwise necessary nailing of the "previous ones" is also superfluous separate dowel, so that aucii occurs over time Zornssoluns of the valuable formwork panels that are now widely used interrupted. Also the difficulties in fastening the previous separate dowels on the Siahl bracket are no longer required through the invention.

The spacers are made of wood, plastic, hard rubber or other nailable material. It is a to itself, to secure the bottom tapered body is a d'ibelartigen hold in the concrete and has ff% from above comes from a deep s, groove-like recess to lie in the reinforcement. '

The groove is so deep that the reinforcement is 10 to 20 mm from the Formwork protrudes; it can be of different depths, it depends on how far the distance between the reinforcement and the formwork or the cover with concrete is desired. The width of the groove can be adapted to the individual dioks of the concrete iron. The body parts standing to the side of the support groove provide a sufficient nail base for fastening the suspended ceiling Installation parts and the like.

In the pictures, the innovation is represented by an approximately cube-shaped Body shown for example.

Figure 1 shows a body 1) made of wood-concrete in roughly natural size, once from the front and once from the side. In the incision 2) the reinforcement 3) lies in such a way that it has a distance of approx. 15 mm from the formwork 4). The sole 5) under the incision 2) is not evenly thick but is reinforced towards the center of the incision. This reinforcement can be arch-shaped, roof-shaped, rib-shaped "or the increase can be brought about by an inserted wire or the like * As a result, the reinforcement is only punctiform in the request of the incision" so that the reinforcement also ix. The incision can be undercut laterally from below with concrete «

The elevations 6) next to the incision are kept in their dimensions in such a way that they are sufficient Nail base result, they also prevent the spacing can be pushed away under the reinforcement «

In Figure 2, three of the spacer dowels 1) are in one Concrete ceiling 7) shown lying down. They lie under the B & ustshl mat 3) at the required intervals in each case, but they can too under single /, rmi get sticks or braided into baskets » Reinforcement lie.

For several reinforcing bars lying at short intervals the body has 1 * rod shape with several incisions, as Fig. 3 shows. The incisions 2) have the necessary spacing from one another and thus ensure the spacing of the Bars from the formwork as well as from each other · The small notches 8) in the underside of the bar 1 * are used for Recognition of the position of the concreted iron and the nail base 8 ·

The arch 10) dor wire loop 9) bo is attached in the sole so that it serves as a point © support 5) for the reinforcement. The two ends of the wire loop 9) are used to tie the body 1). Instead of the binding wire 9), a resilient clamp can be pressed in, or the support 5) designed as a rib is raised laterally on both elevations 6) and the distance between the two rib knuckles is adapted to the diameter of the iron rod so that the body by means of the rib knuckle the J *
