Spacers for reinforcement soaps _?

Spacers for reinforcing bars are known in various embodiments and are used in particular in the production of reinforced concrete ceilings ^ reinforced concrete slabs and the like; in general, these spacers have the task of keeping the lowest layer of the reinforcing bars at - a certain distance from the formwork or the floor slab of a? and they are now mostly designed as a base piece or as a part that can be slipped onto the reinforcement iron. Distances ^ wipe reinforcing steel and formwork Tqzw ₀ mold plate / are respected _for why find different sized spacers used in these Mllen? Often, however, it is also useful to ensure that certain height differences are maintained between different layers of parallel or intersecting reinforcing bars ^ or can the task be given in the case of shapes? To be able to ensure the desired distance between the base plate and the cover plate of the mold over the entire surface

od «dglο _{t to} provide what, however, manufacture, in the storage and in the assembly would lead to a great effort.

The invention is based on the object of a spacer to be created for reinforcing iron, it can be produced at low cost and can be used in a variety of ways is. In particular, the spacer should be usable in the manufacture of reinforced concrete slabs «.

The invention relates to a spacer for Armieruiigsöiaen which is provided with an open-edged Sohlitz for receiving a reinforcing rod "The invention consists in that the spacer is designed as an elongate Kunststoffkflrperausgebildet, the bswi at one end into two on the formwork, the bottom plate of a mold attachable , legs that are elastically pushed apart and that form a clamping or hasty seat between them for a first armoring seieexi, and which in the area of its other end3 has another? has elastic aufwei & iaren receiving slots for an adjacent rebar.

Such a spacer can be used in a simple V / eise to produce a distance between the lowermost layer of the reinforcing iron and the. For "formwork use, the Läng © provided for at the lower end of leg, or ^'v' die'9 IEFE are the sswischen these two legs" to iufnahraeschlitssss, - the distance determined by bessernde-

The rest of the advantage, however, is that these spacers are also due to their two spaced apart receiving slots can be used between the to ensure a certain distance between the bottom and a second bottom biae? For this purpose, the Spacers are first pressed with their lower end onto the reinforcement bars, and after laying the lowest The reinforcement bars of the second layer are in the upper receiving slots provided on the spacers are imprinted «Since the spacers are each on the reinforcement bars are clamped on, these are against a Falling off the sticks secured · A special one the spacers are firmly seated on the reinforcement bars achieved according to a further feature of the invention in that the receiving slots have an inner, in cross-section circular part encompass the under formation from 3 branch noses into one that widens outwards Scixlitz part passes,

The spacer according to the invention can also be used to solve a further special problem, which consists in building a multi-layer grid of reinforcing iron, in which between the individual layers the desired distance can be maintained. For this purpose, after the two lower layers in have been mounted in the manner described, weiter.Abstandhalter with their lower receiving slot on the iron set in the second tier, and the biscuits in the third tier

pressed into their slots. Let accordingly assemble the other layers.

The upper receiving slot of each spacer can in this case be carried out in various ways "Thus in a further embodiment of the invention may be provided that the spacer has at both ends in opposite directions toward open edge Aufnahemschlitze» either offset in parallel or at 90 ° to one another are _o Is is but it is also possible that the spacer apart from its lower receiving slot for receiving intersecting reinforcing irons is provided on a longitudinal side bit with a substantially horizontally located receiving slot into which the reinforcing irons of the higher layer are pressed laterally. If the spacer is used to accommodate two very differently dimensioned reinforcing bars, it is expediently provided that the spacer is designed with different overall widths at both ends »

The subject matter of the invention is divided into two forms below management examples described with reference to the drawing, in the pointers

The spacer has east noses 731 and 741 at the transition point between these two Seülitsteile. When the spacer 7 is pressed onto the reinforcing iron 8, the elastic legs are pressed apart so that the reinforcing iron engages in the circular slot part 711. The receiving slots 71? 72 differently dimensioned. In order to keep material consumption as low as possible, the outer dimensions of the spacer in the upper and lower area are also limited to what is just required »

In FIG. 1, the spacer 7 is seated on the base plate 10 a 3? orm and thus secures the distance at the same time between the lower reinforcing iron 8 and the plate 10 as well as the distance between the two reinforcing bars 8

Of course, further modifications of the invention are possible. For example, for securing the distance between crossing spacers, a design can also be provided in which the upper slot shown in FIGS the S'igc 4 to 6 also the upper end of the spacer?
