Reinforcement element for reinforced concrete components

The invention relates to reinforcement elements for reinforced concrete components of all kinds, in particular slabs, supports, beams or the like., which consists of several structural steel bars located in the components, which are connected to one another by pieces of wire or rods or brackets are, exist

There has long been a need for the reinforcement of reinforced concrete components To have prefabricated reinforcement elements available that adapt to the dimensions of the components leave, i.e. in one or more dimensions / are changeable. Such resizable and prefabricated reinforcement

elements can be used much more universally, can be manufactured more efficiently and are also easier to handle than this the previously common method of manufacturing and applying reinforcement elements, which are usually made on the construction site Rods and brackets or the like. tied together or welded or be bent from welded welded wire mesh is possible.

Sometimes it is common to use prefabricated elements in the form of a ladder or the like, through which the very wage-intensive, Conventional methods of producing reinforcement elements on the construction site are somewhat facilitated. These elements However, they can only be used if the two reinforcing bars of the ladder elements are the correct distance from one another to have. However, since the storage of ladders with very finely graduated bar spacings is practically impossible, the Application of these ladder elements is limited.

The production of reinforcement cages and the like with the help of curved Welded wire mesh offers a wide range of options in terms of shape, width and height, but does not fulfill the intention fully to move this processing from the construction site to the factory. In addition, the curved, welded mats are static Can only be used to a limited extent.

The invention is based on the object of reinforcing elements create that combine three properties required by the consumer, namely a real, fully valid prefabricated To be a reinforcement element, a change in the distance between the reinforcing bars from one another within certain limits

to allow and be easily transportable, doh. that it takes up as little space as possible for transport.

To solve the problem it is proposed according to the invention, Reinforcement elements for reinforced concrete components, such as in particular Plates, supports, girders, pipes or the like made up of several structural steel rods lying in the components, which by means of Wire or rod pieces or stirrups are connected to one another, are to be designed in such a way that two immediately side by side or opposite reinforcement members such as reinforcing bars, rings, mats, ladders, etc., by means of more flexible, any bar spacing within certain limits retaining and connecting elements that can be adjusted, preferably made of round or flat material, i.e. made of Wires, rods or sheet metal strips are connected to one another at variable distances.

The basic links for the variable-width reinforcement bodies according to the invention are reinforcement bars, reinforcement rings, Welded wire mesh, reinforcement ladders, etc., which run through perpendicular or at any angle to the longitudinal axis Wires, rods, sheet metal strips or the like. in the same or different Divisions non-positively and / or positively rigid or optionally also variable in distance are connected · The dimensions of the reinforcement links and the connecting elements can be varied as required.

009821/0890

The one relating to the reinforcement elements in question Invention therefore consists in the fact that two or more? «Der Reinforcing bars parallel to one another are connected to one another in such a way that these bars can be shifted laterally relative to one another is possible to adapt the reinforcement element to the required dimensions; for the purpose of transport, the individual elements are compressed so that the rods are tight against each other.

The flexible, but sufficiently rigid connecting elements, which consist of wires or ribbon-shaped strips, can be welded, clamped, tied to the reinforcing bars or in any other suitable manner, e.g. by means of a Sliding sleeve or the like. be attached.

The rods at a certain adjustable distance from each other holding connecting elements in the form of a wire or flat band can also have one or more kinks, i.e. bent in a zigzag shape so that they are more or less stretched depending on the desired distance between them. other connecting reinforcing bars.

If you use flat strips of tape as connecting elements, so you can stiffen these advantageously in their straight sections between two kink lines by embossed ribs.

Instead of the zigzag-shaped connecting elements provided with several kinks, it is possible to use spiral-shaped To use fasteners that are also more or less far apart or compressed in their length

can be to the reinforcement bars in a desired, to keep a predetermined distance.

According to a further feature of the invention, the connecting elements can be attached to the reinforcing rods with their ends in such a way that portions of their ends over the Reinforcing bars protrude and designed as spacers are, so that it is achieved by this that the reinforcement element used in a formwork in a certain Distance from the formwork and completely embedded in the concrete is, while maintaining a certain distance from the outer surfaces.

The fastening of the connecting elements to the reinforcement bars can be done in any way. Since steel wires with a sufficient cross-section are advantageous for the connecting rods are used, which can be bent back and forth several times without risk at their kinks, they will expediently welded on; but you can also clamp them by bending the ends around the bars several times, so that they are stuck or can be moved on the bars.

The reinforcement elements designed according to the invention for reinforced concrete components can have a wide variety of shapes. So it is possible to produce mat-shaped reinforcement members, in which the reinforcing bars are arranged parallel to each other and are held together by the connecting elements, so

that it is possible to use the rebar in a specific, to give mutual distance from one another, which of course is only possible within certain limits.

Furthermore, reinforcement elements can be made from two construction meshes customary training exist that by the invention Fasteners are held together around the two 'welded wire meshes located parallel to each other in a certain to keep the desired distance from eJnaader

It is also possible to use ladder-shaped reinforcement members, each consisting of two reinforcing rods lying parallel to one another, which are connected by a wire or wire bent in a zigzag shape are connected to each other by individual connecting rods, by means of the connecting elements according to the invention to form a reinforcement element in which the depth of the reinforcement element is given by the ladder-shaped individual members and in which the distance of the same from each other on a can be set to a certain degree.

The application of the invention to reinforcements for concrete supports is particularly advantageous. Here, they can be parallel to each other and reinforcing bars located at the corners of the components are held together by the connecting elements, so that the rod spacing can be adjusted to a desired level. A device according to the invention can also be used to reinforce drilling designed reinforcement element are used, in which parallel closed entrances from

In the embodiment according to. Fig. 5 and 6 are four lying on the longitudinal edges, for example, a reinforced concrete support structural steel Letter 21, 22, 23 and 24 tahldrähte by ^ü or rods connected to each other "between the two Armierungsstaben 21 and 22 or 23 and 24 · is located, a respective Zigzag-shaped bent steel bar or wire 25 and 26, which are welded to the reinforcing bars each enclose the same angle to the reinforcing bars between their fastening points. If the reinforcing bars 21 and 22 are axially displaced relative to the reinforcing bars 23 and 24, the angle between the connecting bars 27 or 28 and the reinforcing bars changes, whereby the distance between the reinforcing bars 21 and 22 and the reinforcing bars 23 and 24 is changed.

This can be seen particularly clearly from FIG. Are located the end faces of the reinforcing bars 21 and 23 are the same Height and the connecting rod 27 between these two has an inclination of about 45 °, the distance X between increases the locking rods 21 and 23, if the reinforcing rod 23 axially downwards relative to the rod 21, from position A to position B, in which the connecting rod 27 with respect to the reinforcing rods 21 and 23 includes a right angle. In this legend the reinforcing bars have 21 and 23 respectively the greatest distance XB from each other. If you move the armie

rujigsstab 23 - from position A to position O, the angle between the connecting rod 27 and the reinforcing rods 21 or 23 becomes smaller and the distance XO between the reinforcing rods 21 and 23 becomes smaller. However, the end faces of the reinforcing bars 21 and 23 only have the same height in position A. The end face of the rod 23 is at a different height from that of the rod 21 in all other positions. If necessary, the reinforcing bars can be cut at the ends after setting the desired spacing of the reinforcing bars so that the end faces are all in the same plane. - ..

To keep the loss due to cut off rod ends small, it is expedient to give the connecting rods 27 a certain To give optimal inclination when the end faces of the reinforcing bars are all in one plane.

As the embodiment according to FIG. 8 shows, the reinforcing bars 21 and 22 ^f or 23 'and 24' are connected to one another in the form of a ladder by rigid bars 29 and 30, respectively. Between the rods 21 and 23 * or 22 'and 24 *, connecting wires 31 and 32 are arranged with their ends attached to them, which have several kinks 33 and are thus designed in a zigzag shape. These connecting rods 31 and 32, respectively can now, as FIG. 9 shows, lie in a plane transversely or perpendicular to the reinforcing rods 21 ', 23' or 22 ', 24'. However, it is also possible, as can be seen in FIG. 10, ^{to arrange the connecting rods 31 f in} such a way that they are connected in the plane of the

009821/0890

~ * ° ~ 16098U / 3

which reinforcing bars 21 ',. 23 'lie. The reinforcement elements 4 to 6 can be changed in their width in that one of the opposing reinforcing bars 21 ', 23' or 22 ', 24 * press against one another or one another pulls away, wherein the connecting wires 31 and 32 are kinked or stretched more strongly.

The connecting rods used are thinner structural steel rods or wires that are sufficiently rigid on the one hand to hold the reinforcing rods in to keep the desired distance and, on the other hand, can still be bent without effort and also a multiple bending enable.

Appropriately, the connecting wires 34 between each two reinforcing rods 35 with their ends welded to them, as can be seen from Mg. 11, for example.

If connecting elements are used, regardless of whether they are made of round or flat material, which have at least one kink between the fastening points (Figs. 1 to 4, 8, 9, 10), there is the advantage that the reinforcing bars are not shifted against each other, if they have different distances from one another, ie that the end faces of all reinforcing bars are in the same plane.

If band-shaped connecting strips 36 or 37 made of flat material, such as steel bands, are used, then these in the manner shown in FIGS. 12 and 13 the rods 3Θ or 39, i.e. by clamping

or advantageously by welding. TJm such fasteners To give greater rigidity, ribs 40 are in each case between the kink points of the strip strips or 41 embossed into the straight sections 36a, 36b or 37a, 37b.

But it is also possible to provide strip-shaped connecting elements 42 with a larger number of kinks "as in Pig. 14 shown »

Another possibility is to use fasteners 43 »which are spirally wound and which also have an adjustment of the interconnected by them Reinforcing bars 44 allow a certain distance, as fig. 15 shows.

Since it is of particular importance when using the reinforcement elements that the reinforcing bars in a certain Distance from the surrounding formwork S to be filled with concrete - see Pig. 16-, are proving beneficial the ends 45 of the connecting elements 46 made of wire to stand holders' 47 shaped or bent. An embodiment is shown in Fig. 17; with this are the ends 45 bent around the reinforcing rods 48 several times to form a loop as a spacer 47. Of course it is also possible to attach the ends of the connecting wires to the Welding reinforcements.

To reinforce reinforced concrete columns with a triangular cross-section as shown in FIG. 18, one can also use the Use reinforcement elements for rectangular columns; for this purpose, it is only necessary to fold two of the opposing reinforcing rods 49 and 50 while kneeling to bring them together connecting wires 51. The reinforcing bars 49 and 50 are advantageously secured by a clamp 52 held together.

For the reinforcement of pipes or the like. A reinforcing element can be used, which in the Pig. 19 can be seen Way is formed. From reinforcing rods existing rings 53, which are parallel to each other, are connected by connecting wires 54 so that the individual Allow rings 53 to be set to any distance X by turning them against each other, the largest possible distance X is determined by the sections of the connecting wires between the rings. -
