Solution Overview
Problem
Existing systems for statically loadable components in structures face limitations in flexibility due to different safety concepts and test procedures for tension rods and cable tension members, making it difficult to easily switch between these components without significant reconstruction efforts.
Innovation Solution
A system with statically loadable components featuring tension elements with outer threads of equal load capacity, allowing for the same threshold tensile force across different elements, enabling easy replacement and combination of tension rods and cable tension members using a unified connection component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different safety concepts and test procedures are applied to tension rods and cable tension members, then the load-carrying capacity and breaking forces can be optimized for each component type, but the flexibility to switch between component types is severely limited
Solution Approach 1:
The connection component is designed with a universal inner thread that can interact with outer threads of different tension elements (tension rods and cable tension members). This allows a single connection component to serve multiple functions by accommodating different tension element types while maintaining standardized thread interactions, thereby enabling flexible substitution between component types without requiring component-specific connection hardware
2Strength
If tension elements are designed with different thread specifications to meet各自的安全要求, then the breaking force requirements can be satisfied, but significant reconstruction efforts are needed when switching between tension rods and cable tension members
Solution Approach 1:
The invention standardizes the thread parameters (inner thread of connection component and outer thread of tension elements) across different tension element types. By maintaining consistent thread specifications while allowing different tension element geometries, the system enables easy substitution between tension rods and cable tension members without requiring reconstruction of threaded connections, thus reducing manufacturing and replacement efforts

AI summary
The present application relates to a system consisting of statically loadable components for structures, including at least two different tension elements (10, 14), each with at least one end region (11, 15), which have an outer thread (12, 16) in their end region (11, 15), and at least one connection component (20, 20′, 30) with an inner thread (22) which is configured to interact with the outer thread (12, 16) of one of the tension elements (10, 14) as a tension member. According to the invention, the outer threads (12, 16) of the at least two different tension elements (10, 14) have the same thread load capacity and determine a respective threshold tensile force of the at least two different tension elements (10, 14).
