Insulated Concrete Structure With Nested Metal Skeletons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current civil engineering methods for constructing concrete structures are laborious, time-consuming, and costly due to the need for multiple concrete casts, long waiting periods for solidification, and the requirement for a strong skeleton and extensive labor, which hinders the creation of isolated and portable structures efficiently.
Innovation Solution
A structure comprising inner and outer metal skeletons with a cage-like design, where concrete is cast between them in a single step, allowing for efficient construction, isolation, and transportability, with the space between the skeletons serving for insulation and piping, and using surrounding beams for structural support and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional multi-step concrete construction method is used, then structural strength is ensured, but construction time and labor costs increase significantly
Solution Approach 1:
The structure is divided into inner and outer skeletons with distinct functions. The inner skeleton provides structural support while the outer skeleton serves as formwork support and insulation framework. This segmentation allows simultaneous preparation of both skeletons before single-step concrete casting, eliminating sequential waiting periods while maintaining structural integrity requirements.
Solution Approach 2:
Both inner and outer skeletons are assembled and positioned in advance before concrete casting. The inner skeleton is prepared within the inner space defined by the outer skeleton, and all reinforcement rods are installed beforehand. This preliminary preparation enables the concrete to be cast in a single operation into the pre-configured space, eliminating multiple casting steps and waiting periods between them.
2Stability of the object's composition
If traditional concrete construction is used, then structural stability is achieved, but the number of employees and labor costs increase
Solution Approach 1:
The construction process merges multiple traditional steps into a single concrete casting operation. The inner and outer skeletons, reinforcement rods, and formwork are all prepared and positioned beforehand, allowing concrete to be cast once to complete the entire structure. This combines skeleton assembly, reinforcement installation, and concrete pouring into one integrated process, reducing labor requirements while maintaining structural stability through the combined skeleton system.
Solution Approach 2:
The outer skeleton serves multiple functions: it acts as the support structure for formwork during concrete casting, provides a framework for insulation material placement, and defines the outer boundaries of the concrete structure. This multi-functionality reduces the need for separate components and labor for each function, improving productivity while ensuring structural stability.
3Loss of time
If single-step concrete casting is used, then construction time is reduced, but structural strength and stability may be compromised
Solution Approach 1:
The inner skeleton is nested within the inner space defined by the outer skeleton. This nested configuration allows both skeletons to work together as an integrated reinforcement system during single-step concrete casting. The inner skeleton provides internal structural support while the outer skeleton maintains formwork stability, ensuring that structural strength requirements are met even though concrete is cast in a single operation rather than sequentially.
4Object-affected harmful factors
If traditional construction method is used, then insulation can be added, but the structure becomes less portable and requires more complex assembly
Solution Approach 1:
The insulation space is created in the third dimension between the inner and outer skeletons, rather than adding insulation layers sequentially to the exterior. This spatial arrangement allows insulation material to be placed in the void space during the same construction phase as the skeleton assembly, integrating insulation into the structural design rather than treating it as a separate additive step. This reduces overall structure complexity while maintaining insulation effectiveness.
