Insulating Shell Composite with Recessed Cavity for Ring Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring anchors in masonry construction are inefficient in terms of thermal insulation, require significant material and time for production, and have limited space for reinforcement due to the use of formwork and U-shaped shells, leading to cold bridges and suboptimal structural reinforcement.
Innovation Solution
The development of an insulating shell composite with two insulating shells and a ring anchor, where each shell has an insulating board with a recess for a concrete core, allowing for form-fitting fixation and thermal insulation enhancement, along with a C-shaped bracket for stable positioning, eliminating the need for formwork and enabling easier handling and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional formwork is used for ring anchor production, then structural integrity is achieved, but material consumption and production time increase significantly
Solution Approach 1:
The insulating shell composite is pre-assembled at the factory with insulating boards, brackets, and reinforcement positioning elements before delivery to the construction site. This preliminary preparation eliminates on-site formwork assembly and accelerates the ring anchor production process while maintaining structural integrity through precise factory-controlled manufacturing.
Solution Approach 2:
The formwork element is extracted and replaced by the insulating shell composite that serves both as insulation and as a permanent form for the concrete core. The insulating board with its cavity structure provides the necessary containment for concrete pouring without requiring additional formwork materials.
2Strength
If conventional formwork is used for ring anchor production, then structural integrity is achieved, but material consumption increases
Solution Approach 1:
The formwork element is extracted and replaced by the insulating shell composite that serves both as insulation and as a permanent form for the concrete core. The insulating board with its cavity structure provides the necessary containment for concrete pouring without requiring additional formwork materials.
Solution Approach 2:
The insulating shell composite merges the functions of thermal insulation and formwork into a single integrated component. The insulating board simultaneously provides thermal insulation and serves as the permanent form that contains the concrete core, eliminating the need for separate formwork materials.
3Temperature
If U-shaped shells are used for ring anchor, then some insulation is provided, but the cross-section for reinforcement insertion is very limited
Solution Approach 1:
The insulating board is designed with a cavity that provides localized insulation exactly where needed around the concrete core, while the overall geometry of the insulating shell composite maximizes the available cross-sectional area for reinforcement insertion. The cavity shape and positioning are optimized to provide thermal insulation without compromising the space available for structural elements.
4Strength
If conventional ring anchors are used, then structural function is achieved, but cold bridges occur due to insufficient insulation
Solution Approach 1:
The insulating shell composite uses a composite structure combining the insulating board material with the concrete core and metal brackets. This composite design ensures thermal insulation continuity around the entire concrete core, eliminating cold bridge pathways while maintaining structural function through the integrated design of insulation and load-bearing elements.
