Tubular Reinforcing Element, Method for Producing a Reinforcing Element, Global Reinforcement, Use of a Reinforcing Element, Concrete Structural Part and Program File

Abstract

The invention relates to a tubular reinforcement element (1) that is formed in a grid shape from a continuously arranged intersecting yarn (2), wherein the intersecting sections (3) of the at least one yarn (2) is connected to one another by a cross-connection. According to the invention, the cross-connection of the yarn (2) is implemented by a material means or a mechanical means, wherein the means determines the shear elasticity of the cross-connection, the elasticity during the counteractive pivoting movement of the crossing sections (3) about their crossing point in the cross-connection, and thereby determines the extensibility of the reinforcement element (1) in the direction of a longitudinal axis, a higher shear elasticity being accompanied by higher extensibility. The invention further relates to a method of producing the tubular reinforcement element (1) by weaving, braiding, or winding the grid structure from a yarn (2). Other aspects of the invention relate to a global reinforcement, a use, a concrete component, and a program file.
