Formwork Element Reinforcement Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional formwork elements require a large number of connecting elements to fix wire structures, making them heavy and expensive, as they need to be spaced every 15 cm to form a ring around reinforcing bars, increasing the complexity and cost of the reinforcement cage setup.
Innovation Solution
The reinforcement component features latching elements for connection to formwork elements and a longitudinal web with laterally protruding webs, allowing wire structures to be connected between these elements, reducing the need for additional connecting elements and enabling efficient positioning of reinforcing bars with a skeleton structure that allows even concrete distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting elements are spaced every 15 cm to form a ring around reinforcing bars, then wire structures can be properly fixed, but the number of connecting elements increases to 15 for a 2 m formwork element, making it heavy and expensive
Solution Approach 1:
The patent introduces reinforcement components as intermediary elements between the connecting elements and wire structures. These components have receptacles that accept wire structures and are attached to connecting elements, allowing wire structures to be fixed at intermediate positions without requiring additional connecting elements at every 15 cm interval.
Solution Approach 2:
The reinforcement components extend in the longitudinal direction between connecting elements, utilizing the space dimension along the formwork length. By positioning these components at intermediate locations and attaching wire structures to them, the system achieves proper wire structure fixation without increasing the number of transverse connecting elements.
2Manufacturing precision
If 15 connecting elements are used for a 2 m formwork element to fix wire structures, then wire structures can be properly positioned, but the complexity and cost of the reinforcement cage setup increases
Solution Approach 1:
The system is segmented into three main components: connecting elements (attached to formwork panels), reinforcement components (intermediate elements with receptacles), and wire structures (for tying reinforcing bars). This segmentation allows each component to perform its specific function, simplifying the overall setup process while maintaining positioning accuracy.
Solution Approach 2:
The reinforcement components are pre-equipped with receptacles designed to accept wire structures. This preliminary preparation allows for quick and accurate positioning of reinforcing bars and wire structures during assembly, reducing on-site complexity and improving manufacturing precision without requiring complex adjustment mechanisms.
3Weight of stationary object
If the number of connecting elements is reduced to 4 for a 2 m formwork element, then the formwork element becomes lighter and less expensive, but wire structures cannot be properly fixed at required intervals
Solution Approach 1:
The reinforcement components serve multiple functions: they are attached to connecting elements to provide structural support, and simultaneously provide receptacles for fixing wire structures at intermediate positions. This multi-functionality allows the system to maintain ease of wire structure connection while using fewer connecting elements, thus reducing weight.
