Solution Overview

Problem

Existing concrete reinforcing methods, such as using multilayered sheets with carbon fibers, face issues of increased volume and mass, leading to deterioration from environmental exposures and fire hazards while not effectively enhancing bearing force.

Innovation Solution

A concrete reinforcing material with high-elastic-modulus fibers, woven into a fabric and impregnated with a resin, is inserted into slit holes in the concrete surface, providing enhanced tensile strength without increasing volume or mass, and protected from external exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multilayered sheet with carbon fibers is used for reinforcement, then crack suppression and examination capability are improved, but bearing force enhancement is insufficient and volume/mass increase occurs

Engineering Contradiction:

Improvecrack suppression capabilityVSAvoidbearing force

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent uses a composite material consisting of carbon fiber bundles (high-strength reinforcement) embedded in a transparent polymer matrix (protective and bonding medium). This composite structure provides both crack suppression through the carbon fiber network and enhanced bearing force through the synergistic interaction between fibers and matrix, while maintaining thin profile and transparency for examination purposes.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The reinforcing sheet is designed as a thin film structure with carbon fiber bundles arranged in a planar configuration. This thin film approach enables crack suppression and bearing force enhancement without significant volume or mass increase, distinguishing it from traditional bulky reinforcement methods.

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If multilayered sheet is used for reinforcement, then crack suppression is improved, but deterioration from environmental exposure and fire hazards worsen

Engineering Contradiction:

Improvecrack suppression capabilityVSAvoidenvironmental deterioration and fire resistance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The transparent polymer matrix creates a protective environment around the carbon fiber bundles, isolating them from harmful environmental factors such as moisture, oxygen, and UV radiation. This protective encapsulation prevents deterioration while maintaining the crack suppression functionality of the carbon fibers.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

Solution Approach 2:

The combination of carbon fibers and transparent polymer matrix forms a composite material where the polymer provides environmental resistance and fire protection, while the carbon fibers provide structural reinforcement. This composite structure addresses both mechanical performance and environmental durability requirements.

Inventive Principle:

Principle #40Composite materials

3Strength

If traditional reinforcement methods are used, then bearing force is enhanced, but volume and mass of concrete skeleton increase

Engineering Contradiction:

Improvebearing forceVSAvoidvolume of concrete skeleton

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The patent employs a thin film reinforcing sheet with carbon fiber bundles that provides significant bearing force enhancement while occupying minimal volume. The thin film nature of the reinforcement allows it to be integrated into concrete structures without substantial volume or mass increase, unlike traditional steel reinforcement bars.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The high-strength-to-volume ratio of the carbon fiber-polymer composite material enables effective bearing force enhancement with minimal material quantity. The composite structure maximizes reinforcement efficiency while minimizing volume and mass addition to the concrete skeleton.

Inventive Principle:

Principle #40Composite materials

AI summary

To provide a system for enhancing a bearing force of a concrete skeleton while suppressing increase in at least one of its volume and mass, a concrete reinforced structure is configured to include a skeleton containing concrete having a slit hole linearly formed on a surface layer part of the skeleton; and a concrete reinforcing material having an elongated shape provided to be inserted in the slit hole along a longitudinal direction of the slit hole.
