Self-Climbing Unit Shared Anchor Points Concrete Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing self-climbing systems for concrete building structures require numerous anchor points, leading to structural weakening and increased material and installation costs, as they need to navigate around reinforcement steel during construction.
Innovation Solution
A self-climbing system where climbing and working brackets share anchor points, reducing the number of required anchor points by using paired anchor receptacles and holes, allowing the climbing cylinders to move vertically without external lifting devices, and incorporating hydraulic cylinders for efficient movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous anchor points are used for climbing and working brackets, then the self-climbing unit can be securely anchored, but the structural strength of the concrete building structure is weakened and material costs increase
Solution Approach 1:
The patent combines the anchoring functions of climbing brackets and working brackets into shared anchor points. The climbing brackets and working brackets are both connected to the same anchor points on the concrete building structure, eliminating the need for separate anchor points for each bracket type. This merging reduces the total number of anchor points required while maintaining secure anchoring for both functions.
Solution Approach 2:
The anchor points are designed to serve multiple functions - they anchor both the climbing brackets and the working brackets. This multi-functional design allows a single anchor point to support multiple brackets and perform multiple anchoring tasks, thereby reducing the overall number of anchor points needed in the structure.
2Reliability
If numerous anchor points are used for climbing and working brackets, then secure anchoring is achieved, but material costs and installation expenses increase
Solution Approach 1:
The patent merges the anchoring requirements of climbing and working brackets into shared anchor points, reducing the total quantity of anchor bolts and concrete wall anchors needed. By having both bracket types connect to the same anchor points, the material quantity is significantly reduced compared to using separate anchor points for each bracket type.
3Reliability
If anchor points are positioned at predetermined locations, then secure anchoring is possible, but reinforcement steel must be guided around or removed, leading to structural weakening
Solution Approach 1:
The shared anchor points serve dual purposes for both climbing and working brackets, simplifying the construction process. Instead of needing to plan and execute separate anchoring operations for different bracket types at different locations, the universal anchor points allow for a more streamlined construction approach where reinforcement steel doesn't need to be extensively redirected or removed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces the material and installation costs, minimizes structural weakening, and enables efficient floor-by-floor expansion of concrete structures, allowing for both uniform and varying story heights without the need for external cranes.
Implementation Method 1
climbing cylinders, which are fastened at one end to one of the climbing brackets and at the other end to one of the working brackets and by means of which the working brackets are movable from the second anchor points to third anchor points

AI summary
A self-climbing system with a self-climbing unit in which the climbing brackets and the working brackets each have anchor receptacles which each correspond with one another in their pattern with respect to their relative positions, with the result that, after freeing the anchor holes, which are used by the working brackets, of an anchor point of a concrete wall section of a concrete building structure, the climbing brackets can be anchored in precisely these freed anchor holes of the anchor point. Moreover, the invention relates to a self-climbing unit for an aforementioned self-climbing system and to a method for moving such a self-climbing unit on a concrete building structure.
