Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies fail to effectively prolong the service life of concrete structures, leading to resource waste and environmental pollution when these structures reach the end of their designed service life, necessitating a solution that can enhance the durability of concrete members without altering their original functions.
Innovation Solution
A reinforcing structure comprising corrosion-resistant metal components, such as steel columns, beams, and brackets, is applied to concrete columns, beams, and slabs, forming a composite structure that extends the service life of concrete members by providing additional support and protection without changing the building's original functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If concrete structures are used in construction, then building functions are achieved, but service life is limited leading to resource waste and environmental pollution
Solution Approach 1:
The patent applies composite materials by combining concrete with corrosion-resistant metal components (steel columns, beams, brackets) to create a composite structural system. This composite structure leverages the compressive strength of concrete and the tensile strength/corrosion resistance of metal, thereby extending the service life of the building structure and preventing resource waste when concrete alone reaches its service life limit.
Solution Approach 2:
The patent changes the material parameter of the structural components by introducing corrosion-resistant metal materials alongside concrete. This parameter change enables the structure to withstand longer periods without degradation, directly extending the service life from the conventional concrete limit (50-100 years) to potentially 150 years or more, thus reducing resource waste and environmental pollution from premature demolition.
2Reliability
If concrete structures reach end of service life, then demolition is required, but this causes resource waste and environmental pollution
Solution Approach 1:
By creating a composite structure of concrete and corrosion-resistant metal, the patent enhances the reliability and durability of the building structure. The metal components protect the concrete from degradation and allow the structure to continue serving its purpose beyond the conventional concrete service life, thereby avoiding demolition and its associated environmental pollution.
Solution Approach 2:
The patent applies preliminary action by pre-installing corrosion-resistant metal reinforcement components within the concrete structure during initial construction. This preliminary reinforcement ensures that when the concrete deteriorates over time, the metal framework remains intact and continues to support the building, preventing the need for demolition and reducing environmental harm.
3Duration of action of stationary object
If reinforcing structure is added to concrete buildings, then service life is prolonged, but structural complexity increases
Solution Approach 1:
The patent applies the nested doll principle by placing metal reinforcement components (columns, beams, brackets) within and around the concrete structure. The metal framework is nested within the concrete envelope, creating a hierarchical structure where the inner metal components provide reinforcement while the outer concrete provides protection and finishing, thereby extending service life without excessive external complexity.
Solution Approach 2:
The patent merges the concrete structure with metal reinforcement components into a unified composite system. By combining these materials and integrating them through connection elements, the patent creates a cohesive structure that extends service life while minimizing the appearance of added complexity, as the metal reinforcement becomes an integrated part of the overall building fabric.
