a) Title of the invention

Reinforced prefabricated single component

b) Field of application of the invention

The invention relates to reinforced, prefabricated individual components with a linear reinforcement, such as concrete elements and artificial stones for the construction z. B, road construction, including the construction of crash barriers or barriers, and the construction of parts of buildings and balancing weights, the reinforcement being incorporated for the purposes of breakage during transport. «

c) Characteristic of the known technical solutions

For concrete elements or other artificial stones are known for Zweke strength increase steel reinforcements. These are inserted multi-dimensionally as prefabricated elements in the transverse and longitudinal direction.

However, according to known technical solutions, synthetic fibers are also connected to one another by various production methods in such a way that they can be used as reinforcement. «

In DE-OS 29 30 939 a solution for the production of a creep-resistant, mechanical anchorage is specified, in which the integration of fibers in the building material by the training

The OE-AS 23 57 557 describes a solution in which for reinforcement textile web strip, made of high-strength textile material, coated on at least one side with plastic and turned into a strand.

The achievable solid connection between the reinforcing insert and the plastic foam of the conductive structure is found to be particularly advantageous.

According to DE-OS 29 02 296, it is known to produce annealing elements ( in which glass, plastic or textile fibers are introduced into a tube, which is then poured out with a hardening art.) In this way, an S _t is formed, which can be used as a reinforcing element.

These known solutions, in which plastics or textile fibers are used as reinforcement of prefabricated individual components, adheres to the Hangel, -daß.hehebliche cross sections of the Sewehrungsmaterials must be spent to fulfill the task of holding together the single component after a break to ensure occupational safety.

d) Object of the invention

The aim of the invention is to provide a prefabricated bawehrtes single component, which has a Transportbawehrung, which is inexpensive to produce and allows the use of secondary raw materials.

e) Presentation of the essence the invention

The invention has for its object to provide an armored single component, which has a transport reinforcement of synthetic, preferably textile raw materials, wherein the breakage of des'Einzelbauteiles the existing strength in the reinforcement fully exploited and resulting in the Tranaportbrüchen dynamic forces through the inner Design of the reinforcement to be distributed "According to the invention, this object is achieved in that a line or net-like reinforcement, synthetic, delay; wise textile raw materials, which is primarily positively integrated into the single component, a zugsträgerenden stretchy flexible component, a core, which is surrounded by other flexible components and connected to these non-positively · at least one of dsr components has a smooth lubricious surface on «

Surprisingly, it was found that very high forces can be absorbed in this Weisa with a relatively low-dimensioned reinforcement made of linear-type, in particular synthetic textile secondary raw materials upon breakage of the individual component. The force constricts the core of the reinforcement and the non-positive connection to the surrounding reinforcement components is reduced in connection with the slidability at least one of the reinforcing elements. The locally locally acting force at the break point is thus transferred to a large part of the overall length of the reinforcement, which ensures an extremely high energy absorption. The high energy absorption of the reinforcement according to the invention can be advantageous, for example in the production of concrete protection planking or guide walls in road construction be exploited·

An adaptation to the extent of the energy transfer can be carried out at the sheathing of the core of the reinforcement, by passing through differently tight sheath

kraft · 8 the non-positive connection between the individual reinforcement components or the constriction of the core can be varied by means of a mesh structure «

According to the invention, the tension-bearing core of the reinforcement can consist of high-strength textile material which is surrounded by a lubricious casing and this by a perforated outer casing *

Invention devices can also be slippery and in one? fibrous mantle ¹ "which is surrounded by a strongly perforated outer sheath"

Impact of the adhesive bond is decisive »It is advantageous to use waste film or film made of secondary raw materials as a core material. · Breaking the single component reduces the frictional connection due to the smooth surface due to reduced diameter by increasing the packing density.» As a result, the elongation propagates over the entire length of the reinforcement and an additional sliding takes place, whereby the dynamic forces, which arise during the transport break, are taken up (FIG. 1).

The reinforcement 2 according to FIG. 2 consists of a core-shell construction which consists of tension-carrying textile edge strips (secondary raw materials) in the core 5, which may have a rough surface and which is surrounded by a slippery casing 4, which preferably consists of waste film and a heavily perforated casing 3 are that the entire structure holds together and is not relevant for influencing the bond.
