Solution Overview

Problem

Existing concrete form systems face challenges with high self-load lateral pressure during construction, require temporary installation and removal, and have weak connections with poured concrete, leading to increased construction costs and risks, as well as durability issues due to chemical exposure and corrosion.

Innovation Solution

A highly durable textile reinforcing panel with a lattice-shaped reinforcing material and textile shear connectors is integrated into the concrete structure, providing resistance to lateral pressure and acting as a permanent reinforcing material by being embedded within the cast-in-place concrete, enhancing flexural strength and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional temporary concrete forms are used, then the structure can be formed during construction, but the forms require assembly and disassembly which increases construction time and costs

Engineering Contradiction:

Improveconstruction efficiencyVSAvoidtime for assembling and disassembling forms

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent merges the concrete form function with permanent reinforcing materials by integrating textile reinforcing panels into the concrete structure itself. The textile panels serve dual purposes: as temporary forms during construction and as permanent reinforcement in the cured concrete, eliminating the need for separate form assembly and disassembly operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The textile reinforcing panel performs multiple functions: it acts as a temporary concrete form to contain fresh concrete, provides structural reinforcement in the cured concrete, and serves as a permanent part of the structure. This multi-functionality eliminates the need for dedicated temporary forms that must be assembled and disassembled.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If conventional temporary concrete forms are used, then the structure can be formed during construction, but the forms have high self-load which creates safety risks in high places

Engineering Contradiction:

Improveconstruction capabilityVSAvoidsafety in high place construction

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent uses flexible textile reinforcing panels instead of rigid temporary forms. These textile panels have low self-weight while maintaining sufficient strength to contain fresh concrete, significantly reducing safety risks associated with high self-load forms in elevated construction locations.

Inventive Principle:

Principle #30Flexible shells and thin films

3Strength

If conventional concrete forms are used, then the structure can be formed, but the connection between forms and poured concrete is weak

Engineering Contradiction:

Improveconnection strengthVSAvoidconnection mechanism complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent combines the formwork system with the reinforcement system by integrating textile panels directly into the concrete structure. This merging creates inherent strong connections between the form and poured concrete through mechanical interlocking and chemical bonding, eliminating the need for separate connection mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If conventional concrete materials are used, then the structure provides basic strength, but the concrete deteriorates when exposed to chemicals and allows reinforcing bar corrosion

Engineering Contradiction:

ImprovedurabilityVSAvoidchemical exposure and corrosion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses composite textile reinforcing materials with corrosion-resistant properties embedded in concrete, creating a composite structure that provides enhanced durability against chemical exposure and corrosion, protecting both the textile reinforcement and the concrete from degradation.

Inventive Principle:

Principle #40Composite materials

Publication Date: 2019.05.28 KOREA INST OF CIVIL ENG & BUILDING TECH

AI summary

Provided are a highly durable textile reinforcing panel used as a concrete form and a method for constructing a reinforced concrete structure using the same. The highly durable textile reinforcing panel is configured to resist a lateral pressure caused due to a self-load of concrete which is not cured during construction and function as a structure reinforcing material by being integrated with concrete cured after the construction, is integrated with the concrete structure via a textile shear connector formed on a highly durable concrete panel, and allows a lattice-shaped reinforcing material to remarkably increase flexural strength of the highly durable concrete panel, and thus a flexural strength of the entire concrete structure is remarkably increased when the highly durable textile reinforcing panel used as a concrete form is structurally integrated with the concrete structure.
