Another quail! the well-known Aoatandshalter Baskets consists in the fact that they are used to keep vertical reinforcements In particular, suspended mats are poorly suited to vertical formwork. since the temporary Attachment of the well-known spacer basket

very cumbersome and time-consuming on the vertical formwork is. In many cases, spacers for vertical reinforcement, such as those in thicker walls of shark structures are required,? er = sifts. However, this can lead to the suspended reinforcement after pouring the concrete between the vertical formwork no longer over the entire Height run vertically.

The task of the innovation is to create basket-like spacers specify for concrete reinforcement that has approximately the same properties as the conventional spacers show, but with a much simpler manufacture for spacer of horizontal and / or vertical *. * Reinforcements can be used without any special assembly effort, with Ms, £ r.ahs «r. flee against rust On vertical or horizontal exposed concrete ceilings, there is no need for simple fastening options for the spacers are given on vertical formwork.

The object is achieved according to the innovation by a sick-zag-shaped or undulating back and forth Flat body made of plastic, the perforations for the largely unhindered passage of the liquid Has concrete.

Advantageous designs and developments of the solution according to the innovation can follow the features of the claims 2 to 5 and 9 can be taken.

In the case of a basket-like spacer of the type mentioned at a distance from one another, the brackets are connected to one another by several longitudinal bars, the above object is also achieved in such a way that daft the brackets made of plastic have transversely running slot-shaped recesses on their outer edges, which have lateral bulges near their bottoms included, and engage in the slot-shaped recesses flat longitudinal rods with lateral longitudinal ribs,

the latter snap into the side bulges .

Let such new ungereä & e Aboiäuuahaltsrk5r = 3 • I especially simply train them to daji for vertical and horizontal reinforcements are equally well suited.

Advantageous experiences and developments of the further solution according to the innovation; can be found in the features of address 7 to 11. It should be particularly emphasized that the plastic bracket, according to the general solution, can represent transverse sections of an extruded plastic profile body, the plastic profile body advantageously having the profile of the finished bracket. The plastic body can be designed as a hollow body in a material and weight-saving manner, namely the plastic body can pull through several recesses in the shape of a tube in the direction of the length, so that the brackets have round openings.

In the drawings only a few examples are shown.

In Pig. 1, the ready-to-use spacer 1 consists of a flat plastic sheet 2 of a certain minimum rigidity, bent back and forth in the shape of a sick sack. In the ft "hn 2 holes 3 are punched that are as large as möglieh gebalten, except that the track 2 the overlying weight of a reinforcing mat 4 and optionally d» s Qewioht of located on the mat persons without being printed together receive, veer On the other hand, the liquid concrete can pass largely unhindered through the holes. On the upper front edge there are recesses 7 aligned along a center line up to the lateral bending points, in which a transverse rod 8 of the mat 1 engages, the longitudinal rods of which lie on the transverse rods and are connected to them in the usual way.

Renewed & pe spacers 1 IAAt see from one flat], make a flat sheet of plastic that goes through a Stanswerk sum punching out the holes 3 runs and the same or afterwards in the ziek-zag shape or wave-like shape is brought. Depending on the strength of the track and the number of relocations per unit of length, the load-bearing capacity of the spacer Select. The spacers can be easily transported to and from the construction site Bring place. It is also possible to attach the spacers to cross bars 8 of a mat away from the construction site and then to lift the mat together with the attached spacers to the destination. It is immediately clear that the recesses 7 for this ▼ ortellhafterwelse can be designed in such a way that the cross bar 8 in this under a certain pressure snaps into place.

At the one surrounding areas that come to lie in one level 6 de? Volume 1 are in the example fax aligned recesses IO are provided, which run approximately perpendicular to the recesses 7. In these recesses 10 a lengthwise set9b, not shown here, can be used, which is normally not required for spacers for horizontal reinforcement. Means a longitudinal rod that can be inserted into the recesses 10 Is the basket-like spacer also for vertical reinforcement suitable, as Fig. 2 illustrates in more detail.

On a vertical formwork 11, the zigzag-shaped spacer is laid in accordance with FIG. The spacer can be attached to the formwork by means of nails 12 or similar pointed objects. The nails on the inside of the ombend parts are hammered through the plastic material. A longitudinal rod 13 is inserted into the recesses 10 in the bend points, which lie in a plane at a distance from the inner formwork wall, to lie on your Q have 8 of the vertically suspended mat 4. -: i, the longitudinal rods 9 of which run approximately parallel to the longitudinal β-rod 13. The longitudinal rod 13 thus prevents the transverse rods 8 from coming to lie in the valleys of the spacer 1 which is bent in a zigzag shape. It is clear that the Lfingsstab 13 can also consist of a flaoh rod which engages in corresponding seat braids at the bent points of the spacer or is glued to the outside of the bent points. In the latter case, of course, special recesses 10 would be superfluous.

Fig. 3 shows a bracket 20 made of plastic for a innovation according to spacer basket, which consists of a number of brackets 20, which by longitudinal bars 21 in the Distance 1 to each other to a spacer basket, not shown are connectable. The bracket 20 contains

Engagement of a bracket in such a, the Längrippeη in the side bulges 24 of a slot-shaped Recess 23 are able to engage and also lateral Flanks of an incision to both Rare «Ines Bügels BU lie come to this one certain vertical To give hold. At the Pu & ends of the bracket 20 are located Plastic parts 27 protruding like a lobe through the nails 28 sum attaching the bracket to a formwork »» wall can be beaten. Normal catfish "is an attachment of the bracket 20 of a basket according to the innovation a horizontal formwork is not required. However, this is necessary in order to be able to use the brackets 20 and Longitudinal bars 21 built spacer basket also for to be able to use vertical reinforcement.

The bracket 20 according to PIg. 3 can be produced in a particularly simple and economical way from an extruded plastic profile body 29, in which individual disks, indicated by dash-dotted lines, are separated from the body transversely to its longitudinal extent. The recesses 23 are formed by grooves 23 'and the round openings 22 are formed by cavities 22' which pass through the body 29 in a tubular shape. The lip-shaped plastic parts 27 at the foot ends of the bracket 20 are formed by lateral plastic strips 27 ^f .

Such a method for the production of the bracket 20 let much cheaper than the production in one Injection process in special injection forms. This means that the flexible temples can be easily converted into different

Strengths according to different section strengths

on d <a »produce plastic profile body 29, including on these catfish have different rigidity requirements the bracket or the load-bearing capacity of the renewal basket you can easily take this into account.

The innovation is not limited to the exemplary embodiments shown and described in more detail. For the teaching of the innovation, the skilled person offers a number of modifications without any further ·· which, however, do not leave the scope of the innovation. Here also include: rolled plastic bodies old • extra spit or round arch profile, which have selvxi ^ he penetrations at the passage of the concrete nose. Such plastic profile bodies can have lateral guide ladders bub fasten κη vertical formwork, so that they are also suitable for vertical and / or horizontal reinforcement.

you can also look at the one suspended vertically Mat facing flanges of the renewal spacer Kor be s especially on the head sides of the temple according to Pig. 3, hooked parts are located in Direction towards the Torstenen had turned up and up are. Those hook-shaped parts that look like the temples auoh can be made of plastic, can be designed in such a way that they are suspended from cross bars Grip behind mats and thus along the spacer basket fix.
