Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for concrete components are difficult to use, require a dense population of reinforcement anchorages, and are prone to sag due to gravity and concrete weight, offering relatively low tensile capacity.
Innovation Solution
A connection system featuring a rebate former with a backing and stiffening template, coupled with anchors and a stiffening template to prevent or reduce sag, and a method involving a rebate former with a backing and anchors for forming a rebate, using sheet metal and threaded inserts for reinforcement.

Engineering Contradiction Analysis
1Stability of the object's composition
If existing connection systems are used to provide structural connection between concrete components, then connection functionality is achieved, but the systems are prone to sag due to gravity and concrete weight
Solution Approach 1:
The connection system is divided into distinct functional components: rebate formers for geometric configuration, anchors for mechanical attachment, and stiffening templates for structural support. This segmentation allows each component to specialize in addressing specific problems, with stiffening templates specifically targeting sag resistance without compromising overall connection stability.
Solution Approach 2:
Stiffening templates are installed on the rebate formers before concrete pouring to preemptively counteract the sagging effect that will occur under gravity and concrete weight. This preliminary reinforcement prevents deformation during the critical concrete placement and setting phase, ensuring the connection maintains its geometric integrity throughout the process.
2Strength
If existing connection systems use dense population of reinforcement anchorages to achieve adequate tensile capacity, then connection strength is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The invention changes the structural parameters of the rebate former by adding stiffening templates that increase rigidity and load-bearing capacity. This allows the system to achieve adequate tensile capacity through improved structural mechanics rather than through increasing the number of anchors, thereby reducing anchor population density while maintaining required strength levels.
3Ease of operation
If existing connection systems are used, then connection functionality is provided, but they are difficult to use and require dense anchor population
Solution Approach 1:
By segmenting the system into rebate formers, anchors, and stiffening templates with distinct functions, the invention simplifies the overall operation. Each component can be independently handled and installed, reducing the complexity associated with managing dense anchor populations and making the connection system easier to operate on construction sites.
