Description

The present invention relates to a spacer system, with which a spacer device for maintaining a predetermined distance between at least one reinforcement layer of a reinforced concrete component and at least one surface of the reinforced concrete component and / or at least one further reinforcement layer of the reinforced concrete component can be provided. In this case, the spacer device comprises a plurality of interconnected carrier elements, which are designed as cross member elements or as longitudinal carrier elements. At least one support section is provided, which is delimited by at least two transverse support elements and at least two longitudinal support elements.

When building buildings, reinforced concrete is used for various components. For example, reinforced concrete can advantageously be used in the sole, in the ceilings and also in walls, sandwich walls, prefabricated parts, semi-finished parts and rod components. In the reinforced concrete component then at least one reinforcement layer is processed. Depending on the component but also a plurality of spaced-apart reinforcement layers can be used. Due to the reinforcement layers, a reinforced concrete component undergoes special stability.

To produce a reinforced concrete slab, for example, a corresponding formwork is initially provided, in which the lower reinforcement layer is arranged on spacers. The lower reinforcement layer must not rest directly on the formwork. Subsequently, special spacers or support baskets are placed on the lower reinforcement layer, on which then the upper reinforcement layer is placed. Finally, the prepared framework of the reinforced concrete component is poured or encased with concrete.

The spacers or support baskets are used for spacing the one reinforcement layer relative to the formwork or for spacing the two reinforcement layers, wherein the reinforcement layers are provided at a certain distance from each other.

Known spacers or support baskets are usually made of metal rods, wherein metal rods are arranged to each other and connected to each other, that the spacers have a certain height. The known spacers are available in various predetermined sizes.

A disadvantage of the known spacers and support baskets that they can be transported only consuming. The usually very long pre-assembled spacers are very heavy and require a lot of storage space during transport.

In addition, the laying of the known spacers and support baskets consuming. Due to the high weight of the spacers, the spacers are difficult to place in the correct position. In addition, the known spacers and support baskets are difficult to adapt to the existing structural conditions. The spacers and support baskets have to be tailored to the component to be manufactured consuming, for example, to keep a staircase opening in a concrete ceiling. Furthermore, in the known spacers and support baskets, the distance between two reinforcement layers can not be adjusted flexibly.

It is therefore the object of the present invention to provide a spacer system for a reinforcement layer of a concrete component, which is better to transport and is more flexible and easier to use.

This object is achieved by an inventive spacer system with the features of claim 1. Preferred developments and refinements of the invention are the subject of the dependent claims. Further advantages and features of the invention will become apparent from the embodiments.

The spacer system according to the invention serves to provide at least one spacer device for maintaining a predetermined distance between at least one reinforcement layer of at least one reinforced concrete component and at least one surface of the reinforced concrete component and / or at least one further reinforcement layer. In this case, the spacer device provided with the spacer system comprises a plurality of interconnected carrier elements which are designed as cross member elements or as longitudinal carrier elements. The spacer device provides at least two adjoining support sections, which are respectively delimited by at least two transverse support elements and at least two longitudinal support elements. Coupling devices are provided, in which at least some support elements are inserted, whereby a ladder-like structure is provided.

According to the invention provided by the spacer system available spacer device is particularly suitable for use in reinforced concrete ceilings or reinforced concrete floors. The system can also be used for other reinforced concrete components such as walls, sandwich walls, Prefabricated parts, semi-finished parts or rod components can be used.

The spacer device is provided between a reinforcement layer and the formwork and / or between at least two reinforcement layers of the reinforced concrete component. This guarantees a defined or predetermined distance between the surface of the reinforced concrete component and the formwork and / or between two reinforcing layers. In this case, the spacer device can be placed in particular on a lower reinforcement layer or the lower reinforcement layer can be integrated into the spacer device. A second reinforcement layer can then be placed on the spacer device.

According to the invention, a plurality and in particular all carrier elements are preferably inserted into at least one coupling device. In this case, preferably a reversible insertion of the carrier elements in the coupling device is preferred.

In this case, according to the invention, the coupling devices can expediently be provided as a separate part or can also be produced in one piece with at least one carrier element.

The support elements are preferably rod-shaped, rod-shaped or tubular. Thus, by the mating of the carrier elements in conjunction with the coupling device, the ladder-like structure is provided over which the predetermined distance between the formwork and a reinforcement layer and / or between two reinforcement layers of a reinforced concrete component can be adjusted.

The carrier elements can preferably also be hollow at least in sections. This can be saved, inter alia, weight.

Preferably, the predetermined distance is determined by the length of the side rail members. In this case, the ladder-like structure is preferably independent without further fastening means.

According to the invention, a support section is formed by an upper cross member and a lower cross member in conjunction with two side members, which are inserted respectively in coupling devices. Thus, a support portion is provided, in which each of the upper and lower cross member substantially parallel opposite, wherein the two side members are arranged substantially parallel. Thus, a predetermined distance between the lower and upper cross member elements is achieved by the two longitudinal beam elements connecting the cross member elements. For a particularly safe, stable and simple arrangement of the longitudinal support elements and the cross member elements, the support elements are inserted into corresponding coupling devices which connect the longitudinal support elements and the cross member elements. The predetermined distance between the formwork and a reinforcement layer and / or between two reinforcement layers of a reinforced concrete component can then be defined simply by selecting a corresponding length of the longitudinal support elements.

Preferably, the two support sections are provided according to the invention by at least two upper cross member elements and at least two lower cross member elements available. In each case, the upper and lower cross member elements are interconnected by a respective coupling device. Also at the free ends of the cross member coupling means are provided in each case, so that a total of six coupling means are used for the two support sections. The predetermined distance is then set by inserting three side rail members into the coupling means. In such an embodiment, a side member of two adjacent support sections is used. Also two coupling devices are used by two adjacent support sections. These are the two coupling devices which connect the two upper and lower cross member elements.

The spacer system according to the invention offers many advantages. A significant advantage is that a spacer device is provided by the spacer system according to the invention, which is particularly flexible used by the plug-in configuration.

Thus, in particular recesses in a reinforced concrete component can be particularly precisely, quickly and effectively by means of the pluggable spacer holding devices accurately surrounded and unusual outer contours of a reinforced concrete component can be easily designed with the pluggable spacer holding devices according to the invention.

The spacer holding devices according to the invention can be adapted precisely to the corresponding reinforced concrete component. A complex adaptation of conventional spacers or support baskets is eliminated, since the spacers formed by the spacer system according to the invention each individually adapted to the current reinforced concrete component.

In addition, the spacer system according to the invention can be transported easier. Since the spacer devices are designed to be pluggable, the components required for the spacer devices can be transported in individual parts and thus very space-saving. In addition, all individual components can be replenished if necessary to a single location, if certain parts are missing.

Preferably, the spacer device consists at least partially of plastic. In this case, the spacer device preferably consists entirely of plastic, wherein in particular the carrier elements and / or the coupling devices are at least partially and in particular made entirely of plastic. Such a configuration is particularly advantageous, since a particularly lightweight spacer system is provided, which thereby offers considerable advantages in particular during transport and during assembly of the spacer system. Conventional spacers or support baskets made of metal have the required amount of considerable weight, which can lead to enormous transport costs, since the payload of a truck is limited. In addition, conventional metal spacers and support baskets are much more difficult to handle because the heavy spacers and support baskets often need to be moved by crane or other mechanical means. Since the spacers per se are insignificant for the statics of the reinforced concrete component in general, a production of the spacer device is not critical even if the spacer holder device is made entirely of plastic. Another significant advantage is that a spacer holder made of plastic does not corrode. Corrosion is a difficult issue for reinforced concrete components, as metal installed in the reinforced concrete component must not reach the surface of the reinforced concrete component. Since the spacer system according to the invention is preferably made of plastic, this can even come into contact with the surface of the component.

Particularly preferably, the spacer device is suitable and designed to be placed on at least one reinforcement layer. So z. B. a fully assembled spacer device can be easily placed on a lower reinforcement layer, so that the upper reinforcement layer can then be placed on the spacer device or on several spacer holding devices.

In advantageous developments, the spacer device is suitable and designed so that at least one reinforcement layer and / or another component can be inserted into it. As a further component, inter alia, a concrete core activation can be inserted into the spacer device and thereby fixed in position. In particular, the hoses or pipes or heating pipes of the concrete core activation are laid in the spacer device and fixed thereto. For this purpose, preferably clamps and / or clips can be provided or arranged on the spacer device. These embodiments are made possible in particular by the fact that the spacer system according to the present invention is made pluggable.

This can be achieved, inter alia, by first connecting the lower cross member elements by means of the coupling devices. Subsequently, a reinforcement layer and / or another component can be placed on the lower cross member elements. Thereafter, the longitudinal beam elements can be inserted into the coupling device and the upper layer with upper cross member elements can be added to the longitudinal beam elements by coupling means. On the upper cross member elements then the second reinforcement layer can be placed, which is then arranged at a predefined distance to the lower reinforcement layer.

In expedient developments at least one coupling device comprises at least three receptacles for carrier elements. It is particularly preferred that at least a majority of the coupling device or even all coupling devices have at least three receptacles for support elements. So it becomes possible that z. B. in two substantially opposite receptacles each have a cross member element can be used. The third receptacle can then be arranged, for example, essentially at right angles to the other two receptacles, which makes it possible to provide as the third support element a longitudinal support element on the coupling device, which is arranged substantially at right angles to the transverse support elements. Thus, simply a ladder-like structure can be formed.

Preferably, at least one coupling device has at least one receptacle for at least one adapter device, wherein the adapter device is suitable for receiving at least one carrier element. Thus, inter alia, it can be achieved that additional receptacles for carrier devices are made available via adapter devices, these being provided only on the coupling device if additional receptacles are required on the coupling device.

Preferably, the support sections are arranged at an angle to each other. Thus, on the one hand ensures that the ladder-like structure of the support sections can be arranged safely and reliably without further fixing means without further stabilization. In addition, a more stable support surface is provided for the upper reinforcement layer.

In this case, preferably at least one coupling device is designed such that the support sections are arranged at an angle to each other. This can be achieved, for example, by arranging the receptacles for two crossbeam elements of the coupling device at an angle to one another, so that the crossbeam elements are inserted at an angle to one another into the coupling device. As a result, then also the finished mated support sections are arranged at an angle to each other. Particularly preferably, at least a majority and preferably even all coupling devices are designed such that angularly arranged support sections are provided. In this case, the coupling devices are preferably of similar construction, whereby an assembler does not have to pay attention to the use of matching or different coupling devices when assembling the spacer device.

Preferably, at least two receptacles are arranged in at least one coupling device at an angle between 1 ° and 180 ° to each other. Preferably, the angle between the two receptacles between 20 ° and 160 ° and particularly preferably about 135 °. However, the angle may preferably also be 110 °, 120 °, 130 °, 140 ° or 150 °, or else chosen as desired.

Thus, in particular, it can also be achieved that, in preferred embodiments, a plurality of adjacent support sections is provided, wherein the support sections are arranged substantially serpentine. In this case, snake-shaped according to the invention means, in particular, that the carrying sections are essentially zig-zag-shaped, wave-like or curved. By such an arrangement of the support sections to each other can be achieved in particular that the spacer device is safe by itself and also allows a more stable support for the reinforcement layers.

More preferably, at least some coupling devices have at least four receptacles. In particular, the coupling devices preferably have four receptacles which are used in the lower cross member elements. This achieves in advantageous developments that the spacer device can be arranged at a certain distance from a formwork in which the reinforcement layers are arranged for casting or concreting of the reinforced concrete component. In other advantageous embodiments, five, six or more receptacles may be provided on a coupling device. Thus, for example, adjacent spacer devices can be connected to each other.

Then the spacer device particularly preferably comprises at least one spacer element. This spacer element can then be inserted into the fourth receptacle of the coupling devices to produce a defined distance of the spacer device to the formwork. This is necessary because the reinforcement layers must keep a certain distance to the surface of the component. Therefore, the reinforcement layers must not be placed too close to the adjacent surfaces of the component, so that they do not appear on the surface of the component. By the embodiment described above can then be dispensed with separate spacer elements.

In expedient developments, the spacer element in at least one receptacle and / or in at least one adapter device at least one coupling device can be inserted.

Preferably, at least one foot device is provided at the free end of at least one spacer element. In this case, a foot device according to the invention is to be understood as meaning, in particular, a type of pedestal, a support section or an abutment section which comes into contact with the formwork of the reinforced concrete component. Depending on the configuration of the foot device advantageous effects can then be achieved.

In this case, the foot device may particularly preferably be embodied in conical form at least in sections and / or comprise at least one spacer plate and / or comprise at least one spinous process with at least one barb. In the case of a conical configuration of the base, it can be achieved, in particular, that an optimum distance is provided between the lower reinforcing layer and the formwork, without the foot devices being distracting in the finished component in the surface of the component. This is achieved by using the tip of the conical foot device as a contact point on the formwork. Since only the tip of the conical foot device gets up on the formwork, the foot devices in the finished component are almost invisible. Such a configuration is particularly advantageous in exposed concrete, as despite the spacer device a homogeneous Surface is provided. If a concrete core activation is provided in the component, the foot devices may also comprise a spinous process comprising at least one barb. This spinous process can then be inserted, for example, in a Styrofoam layer. Through the barbs, there is a secure connection between the foot and Styrofoam or insulation layer. In addition, if a spacer plate is provided on the foot device, the insertion of the foot device is also limited by the spacer plate, whereby the foot device can be arranged defined in the polystyrene layer.

Particularly preferably, at least one coupling device is manufactured in one piece with at least one carrier element. For example, all longitudinal support elements may be provided at both free ends with a coupling device. Then, during assembly of the spacer means, only the cross member elements must be inserted into the coupling means on the side rail members. Other fixed connections between carrier elements and coupling devices can also be advantageously provided.

In other expedient embodiments, prefabricated support sections and / or parts of support sections can be prefabricated. So it is z. B. possible that side rail elements are provided at both free ends or recordings with coupling means, already cross member elements are inserted at the top and bottom in each case a recording of the coupling device. These already assembled support elements or support sections can then be easily attached to an end of a spacer device during assembly, whereby this is extended in one direction.

At least one support element preferably comprises at least one stabilization device. It is particularly preferred that at least two, preferably a majority and particularly preferably all support elements comprise at least one stabilization device. Stabilizing device according to the invention is understood to mean that the rod-shaped carrier element is processed in this way or comprises additional parts, so that the stability of the carrier element is increased. In particular, it is to be achieved that the stability of the carrier element is improved and, in particular, a bending over or buckling of the carrier element is prevented. For example, the carrier elements can have a star or cross profile. As a result, a too quick folding or buckling of the support elements is prevented. The support elements may also be designed to be hollow in such a configuration.

Further advantages and features of the present invention will become apparent from the embodiments, which are explained below with reference to the accompanying figures.

In 1 is purely schematically a spacer device 2 shown in a sectional view from the side, which with the spacer system according to the invention 1 was made available. This is the spacer device 2 between two reinforcement layers 101 . 102 for a reinforced concrete component 100 , The reinforced concrete component 100 is in the in 1 shown view during manufacture.

In the production of the reinforced concrete component 100 becomes a formwork 103 used, in which initially spacers 107 be inserted. On the spacer elements 107 becomes the lower reinforcement layer 101 hung up. The spacer elements 107 make sure that the reinforcement layer 101 not directly on the formwork 103 rests, as the reinforcement layer 101 otherwise in the finished cast reinforced concrete component 100 directly on the surface 28 of the reinforced concrete component 100 would lie. Between the surface of the reinforced concrete component and the reinforcement layer 101 a standard minimum distance must be maintained, the z. B. in Germany DIN 1045 is determined. For this purpose, in the embodiment shown here separate spacer elements 107 used. These separate spacer elements 107 are z. B. known as U-shaped, star-shaped or rectangular plastic parts.

The lower reinforcement layer 101 and the upper reinforcement layer 102 be in the embodiment shown here by Baustahlgewebe 104 made available. Here is the Baustahlgewebe 104 as a metal grid 104 executed, which consists of cross bars 106 and longitudinal bars 105 is constructed. The reinforcement layers 101 and 102 provide in the reinforced concrete component for sufficient stability, which is particularly necessary if the reinforced concrete component is designed as a reinforced concrete floor or as sole plate. Other components such as walls, sandwich walls, finished parts, semi-finished parts and rod components can be advantageously made of reinforced concrete depending on the purpose.

At a predetermined distance 3 between the lower reinforcement layer 101 and the upper reinforcement layer 102 to make available is between the two reinforcement layers 101 . 102 a spacer device 2 provided, which by the spacer system according to the invention 1 was made available.

In the embodiment shown here, the spacer device comprises 2 six support sections 7 which adjoin one another. The supporting sections 7 be through support elements 4 provided with a support section 7 by at least two cross member elements 5 and at least two side rail members 6 be limited. The carrier elements 4 are in coupling facilities 8th plugged in.

The inventive construction of the spacer device is a ladder-like structure 9 provided a defined distance between the two reinforcement inserts 101 . 102 guaranteed. By the pluggable embodiment of the spacer device 2 A particularly flexible system is made available, which can be particularly easily and practically adapted to the shapes and properties of a reinforced concrete component.

In the embodiment shown here, the spacer device consists 2 in total made of plastic 21 , Here are all support elements 4 and all coupling facilities 8th made of plastic, which makes the spacer system 1 In addition to its advantageous properties described above is particularly easy. This offers further significant advantages.

A significant advantage is that it is due to the lightweight and pluggable design of the spacer system 1 it is possible that the spacer device 2 can be adapted particularly flexibly and precisely for the reinforced concrete component to be manufactured. In addition, the spacer system 1 especially light because it is made of plastic. This can save significant transportation costs associated with the use of conventional spacers or support baskets. These consist usually of a braided wire mesh or wire mesh or metal rods, which alone by the weight of the spacers and the support baskets considerable transport costs arise.

In other embodiments, the spacer system 1 also be made only partially or partially made of plastic. In particular, individual components of the spacer system completely or partially made of plastic 21 be made.

The use of the pluggable spacer device 2 is not a problem, even if it is made entirely of plastic. The spacer device 2 in itself fulfills no static function in the reinforced concrete component, but serves only for spacing the two reinforcement layers 101 . 102 , Thus, it can be achieved by the use of the spacer system according to the invention, the spacer devices 2 can be easily and accurately mated, which can be saved by the particularly lightweight design significant cost.

In 2 is purely schematically a spacer device 2 shown in a perspective view. Again, you can see the adjacent support sections 7 passing through the coupling facilities 8th inserted carrier elements 4 arise.

The carrier elements 4 are designed rod-shaped in the embodiment shown here. By rod-shaped, rod-shaped support elements can be particularly advantageous a conductive structure 9 to provide. In other Embodiments may be at least some support elements 4 also be hollow. By tubular support elements 4 Among other things, even better weight can be saved to improve the transport and handling of the spacer system.

To produce a reinforced concrete component, it is preferable to have more of the spacer means 2 next to each other on a lower reinforcement layer 101 placed to provide sufficient stability for the later on the spacer devices 2 launched second reinforcement layer 102 to reach.

So that no further fastening means for the spacer device 2 necessary, is the spacer device 2 designed in the embodiment shown here essentially snake-shaped. This ensures that the spacer device 2 independently on the lower cross member elements 22 can stand.

As in 2 can be seen, is to be understood by the snake-like configuration of the spacer device in particular that it is constructed substantially wave-like or zig-zag-like. This is achieved by the coupling devices 8th are formed such that the lower cross member elements 22 and the upper cross member elements 23 at a certain angle to each other in the coupling devices 8th can be inserted.

In this case, in the embodiment shown here, all coupling devices 8th built up the same. In other embodiments, the coupling devices 8th be constructed differently, in particular the coupling devices 8th for the upper cross member elements 23 and the lower cross member elements 22 can be designed differently.

In 3 is purely schematically an area of the spacer device 2 according to 2 shown in an enlarged view.

In the embodiment shown here are all coupling devices 8th However, the same training. In this case, the coupling devices include 8th three shots each 10 , in which support elements 4 can be inserted. There are two shots 10 substantially opposite, in each of which a cross member 5 can be inserted. The third recording 10 is essentially perpendicular to the other two shots 10 arranged and serves to receive a side member 6 ,

The two shots 10 for receiving the cross member elements 5 are at an angle in the embodiment shown here 13 arranged to each other, so that the inserted cross member elements 5 adjacent support sections 7 in the angle 13 are arranged to each other. This ensures that the support sections 7 are arranged at an angle to each other, so that depending on the use or arrangement of the coupling devices 8th different wavy patterns for the spacer device 2 can be provided.

The angle 13 between the two shots 10 can be between 1 ° and 180 °, depending on the design. The recordings can be particularly advantageous 10 be arranged in an angular range between 20 ° and 160 °. In the embodiment shown here, the angle is 13 about 135 °. In other embodiments, the coupling devices may also be designed differently, in particular different angles 13 between two shots 10 can be provided. The use of similar coupling devices 8th but offers advantages depending on the intended use. So has a fitter during installation or when mating the spacer device 2 with similar coupling devices 8th not on the use of certain coupling devices 8th respect, think highly of.

In 4 is another embodiment of a spacer device 2 shown purely schematically, which with a spacer system according to the invention 1 was made available. The basic structure of the spacer device 2 corresponds to the embodiment according to the 2 and 3 ,

However, the lower coupling devices 8th differently formed, which in the embodiment shown here not three, but four shots 10 for support elements 4 exhibit. This makes it possible for the fourth down-facing recording 10 a spacer element 14 can be inserted. This spacer element 14 serves a certain distance between formwork 103 and the lower reinforcement layer 101 provide. In such a configuration, the additional spacer elements 107 as they are for example in 1 are omitted, be omitted.

In such an embodiment, then first the lower cross member elements 22 in corresponding coupling devices 8th inserted and it will be the spacer elements 14 connected with these coupling devices. The resulting framework is then placed on the formwork 103 set up for the reinforced concrete component. Subsequently, the lower reinforcement layer 101 on the lower cross member elements 5 be hung up. Thereafter, the longitudinal support elements 6 in the still free admission 10 the coupling devices 8th plugged in and it will be with other coupling devices 8th the upper layer of the cross member elements 5 placed. Then also the upper reinforcement layer 102 on the now finished spacer device 2 be hung up. In such an embodiment, a reinforcement layer is inserted into the spacer device.

The area marked with the dashed box in 4 is below the spacer device 2 in two other alternatives shown purely schematically. Here are the couplings 8th in the two alternatives shown modified so that they take four shots instead 10 one or two shots 11 into which adapter devices 12 can be inserted.

The adapter devices 12 are suitable and designed to support elements 4 and / or spacers 14 take. By such a configuration with recordings 10 for receiving adapter devices 12 it becomes possible that coupling devices 8th can be adapted very flexibly. So it is possible, for example, that a coupling device 8th with two, three, four, five, six or even more shots 10 . 11 can be provided depending on the use. In this case, recordings may be provided to connect two adjacent spacer means together.

In 5 is another embodiment of the spacer device 2 shown purely schematically in a perspective view. Also in this embodiment are spacers 14 in the clutches 8th the lower cross member elements 22 plugged in. In this case, the spacer elements include 14 Fußeinrichtungen 16 , which are conical in the embodiment shown here. This is the top 24 of the cone 25 oriented downwards.

Due to the conical design of the spacer elements 14 or the foot devices 16 is achieved that the spacer device 2 only occasionally on the formwork 103 gets up. So it can be ensured that the spacer elements 14 do not interfere with the surface of the finished reinforced concrete component.

In 6 is purely schematically another embodiment of a spacer device according to the invention 2 shown in a sectional view from the side, which with the spacer system according to the invention 1 was made available. In this case, the spacer device 2 here a predetermined distance between the lower reinforcement layer 101 and the surface 28 and between the two reinforcement layers 101 . 102 to disposal. The reinforced concrete component 100 is in the in 6 shown view during manufacture.

In the production of the reinforced concrete component 100 will be like already 1 described a formwork 103 used. In the embodiment shown here, however, first in the coupling devices 8th inserted lower cross member elements 5 together with the spacer elements 14 on the formwork 103 established. As a result, the spacer elements provided separately in FIG 107 for producing a predetermined distance between the formwork 103 and the lower reinforcement layer 101 in the embodiment shown here by the spacer device 2 made available.

In this case, the spacer elements include 14 in the embodiment shown here Fußeinrichtungen 16 , which are designed cone-shaped. The foot elements 16 are here in one piece with the spacer elements 14 manufactured. Because the cone-shaped foot devices 16 only with the tip on the formwork 103 get up, it is achieved that the spacer elements 14 in the surface of the concrete component are almost not visible or not disturbing. As a result, this spacer system is particularly suitable for exposed concrete. After the lower reinforcement layer 101 on the lower cross member 5 is applied, the longitudinal support elements 6 be plugged into the couplings and it can the upper cross member elements via couplings 8th on the side rails 6 be recorded. On the then assembled spacer system 2 can then the upper reinforcement layer 102 be hung up.

Through the in 6 shown spacer system can have two defined distances in the reinforced concrete component 100 be specified. First, the predetermined distance 3 between the formwork 103 or the surface 28 of the reinforced concrete component and the lower reinforcement layer 101 through the spacer elements 14 be predetermined. On the other hand, the predetermined distance 3 between the two reinforcement layers 101 . 102 predetermined and over the length of the longitudinal beam elements 6 be set.

In the 7 and 8th is another embodiment with spacers 14 shown purely schematically, wherein the spacer elements 14 at the free ends 15 a foot device 16 have a spacer plate 17 and a spinous process 18 with barbs 19 having. The special design of the foot equipment 16 can be used especially when in the reinforced concrete component 1 a concrete core activation 108 is provided or if an insulating layer is provided under the sole.

Then the foot device 16 be plugged for example in a Styrofoam plate, whereby the spacer device 2 through the spinous processes penetrating into the styrofoam plate 18 be kept stable. Through the barbs 19 at the spinous processes 18 In addition, an accidental pulling out of the spacer device 2 prevented.

About the distance tiles 17 becomes a guided penetration of spinous processes 18 ensured in the Styrofoam plate. Here, the spacer plate is used 17 as support surface 26 , which is an end position 27 defined on the polystyrene plate.

In 8th is shown purely schematically that the spacer device 2 in such an embodiment as securing the position of the concrete core activation 108 can be used at a defined distance. This is the spacer device 2 first inserted into the provided below the concrete component perimeter insulation or polyurethane insulation. Subsequently, the heating loops of concrete core activation 108 each in a support section 7 inserted. So can a defined distance of concrete core activation 108 be achieved.

These can also clips or clamps on the spacer device 2 be provided, in which the heating loops can be easily inserted. This ensures sufficient securing of the concrete core activation 108 reached.

In 9 is purely schematic, the top view of a manufactured reinforced concrete component 100 shown, which is a reinforced concrete ceiling 109 in which a hexagonal staircase opening 110 is provided.

Here are in the formwork 103 already the lower cross member elements 22 arranged. Through the plug-in version of the spacer device 2 It is possible here, first around the staircase opening 110 a substantially hexagonal ring of cross member elements 5 to arrange. Starting from this hexagonal ring several spacer devices run 2 essentially serpentine or zigzag-shaped over the base of the reinforced concrete ceiling 109 , It is thereby achieved that, in the embodiment shown here, substantially reticulated spacer devices are arranged 2 perfectly fitting the special features of the reinforced concrete component 100 be adjusted.

On these cross member elements 5 can now the lower reinforcement layer 101 be placed, in which case the spacer device 2 is completely assembled. On the upper cross member elements 23 can then the second reinforcement layer 102 be placed in a defined distance.

In 10 is purely schematically a cross section through a carrier element 4 which is a stabilization device 20 includes. The stabilizer 20 may be provided in other embodiments as a separate part. In the embodiment shown here is the stabilization device 20 however, provided integrally with the support member by a processing step.

In this case, the stabilization device 20 in the embodiment shown here by a certain contouring of the carrier element 4 made available. The carrier element 4 has in the embodiment shown here a cross-shaped cross-section, whereby the rod-shaped carrier element 4 here is particularly stable. Due to the special contour is a kinking of the support element 4 prevented. In other embodiments, other shaped contours can be used appropriately. For example, a star contour and / or a pipe contour is also suitable. In general, the support elements may be round, angular, tubular and / or rod-shaped.

In 10 is further shown purely schematically that the support elements 4 can also be configured hollow.
