Reinforcing Element for Concrete Media Line Installations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concrete structures are weakened by the installation of media lines such as ventilation, electrical, and heating pipes, which compromises their shear-bearing behavior and load-bearing capacity, and existing reinforcement methods are inadequate for addressing these issues during construction.
Innovation Solution
A device that uses structural elements with force models to create force-neutral zones around media lines, allowing for local reinforcement of concrete structures before and after concrete pouring, using components like ZD, SB, and HS models with tension and rigid elements to absorb shear forces and maintain structural integrity.

Engineering Contradiction Analysis
1Adaptability or versatility
If media lines are installed in concrete structures to meet comfort requirements, then the functionality and comfort of the building is improved, but the shear-bearing behavior and load-bearing capacity of the concrete structure is weakened
Solution Approach 1:
The patent applies local quality by creating force-neutral zones specifically around media lines where the concrete structure is weakened. Instead of reinforcing the entire structure uniformly, the solution locally modifies the concrete composition in the immediate vicinity of media lines to compensate for the shear strength loss caused by the cavities and inserts.
Solution Approach 2:
The patent uses composite materials by incorporating reinforcing elements (such as fibers, meshes, or particles) into the concrete mixture in the force-neutral zones. This creates a composite concrete material with enhanced shear-bearing capacity that compensates for the weakening effect of the installed media lines while maintaining the overall structure's integrity.
2Strength
If punching systems are used to reinforce concrete structures, then the reinforcement of support areas is improved, but they are not suitable for addressing media pipe weakening in the middle of concrete structures
Solution Approach 1:
The patent creates a universal reinforcement solution that can be applied to both support areas (where traditional punching systems work) and middle areas (where media lines cause weakening). The force-neutral zone concept with composite concrete is universally applicable regardless of the location or type of media lines, making the solution versatile for various reinforcement needs.
Solution Approach 2:
The patent segments the concrete structure into different zones: force-neutral zones around media lines where composite concrete is used, and regular concrete zones elsewhere. This segmentation allows targeted reinforcement only where needed (around media lines) rather than reinforcing the entire structure, making the solution adaptable to different locations and media line configurations.
3Strength
If special devices are installed locally at points of weakening to compensate for media lines, then the load-bearing capacity is maintained, but the device complexity and installation requirements increase
Solution Approach 1:
The patent merges the reinforcement function with the concrete pouring process itself. The reinforcing elements are incorporated into the concrete mixture before pouring, so the reinforcement is created as an integral part of the concrete structure rather than as a separate device installed afterward. This eliminates the need for complex post-installation reinforcement devices.
Solution Approach 2:
The concrete mixture itself provides the reinforcement function through the incorporated reinforcing elements. The concrete performs the dual function of structural material and reinforcement carrier, eliminating the need for separate reinforcement devices. The force-neutral zones self-reinforce through the composite material properties rather than requiring external reinforcement systems.

AI summary
Components (1, 21) are presented which can almost or completely eliminate any weakening of a concrete structure (10) caused by internal components (20), e.g., utility lines. The internal components (20) are surrounded by at least one component (1, 21) which transmits the forces and thereby creates a force model that forms force-neutral zones (31) for the internal components. The component (1, 21) consists of a tension element (2) and an anchorage (3) at least at one end.
