Asymmetrical Anchor Point Distribution in Wall Formwork
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall formworks face challenges in flexible anchoring and compatibility with different dimensions, leading to inefficient assembly, high storage needs, and limited adaptability to varying concrete pressures.
Innovation Solution
The wall formwork design features asymmetrical distribution of anchor points, with more points in the upper portion than the lower, allowing for adjustable anchoring based on concrete pressure, and the option to close unused anchor holes, enabling flexible anchoring and compatibility with various dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If anchor points are arranged symmetrically in conventional wall formworks, then the structure is simple and easy to manufacture, but flexible anchoring and adaptability to different dimensions are limited
Solution Approach 1:
The patent applies asymmetry by distributing anchor points unevenly between the upper and lower portions of the wall formwork. Specifically, the upper portion is equipped with more anchor points than the lower portion, allowing flexible anchoring configurations adapted to varying concrete pressures at different heights. This asymmetric arrangement enables the formwork to handle different loading conditions while maintaining a relatively simple overall structure.
2Adaptability or versatility
If multiple wall formworks with different dimensions are stored to prepare large-surface wall formworks, then complete wall formworks can be assembled, but storage needs and complexity increase
Solution Approach 1:
The patent implements universality by designing a standardized asymmetric anchor point distribution that can be applied across wall formworks of different dimensions. The upper portion consistently has more anchor points than the lower portion regardless of the specific wall size, allowing a reduced set of standardized formwork components to be used for assembling various wall dimensions. This reduces the need to store multiple specialized formwork sets.
3Reliability
If anchor points are optimized for a given maximum load, then the anchoring is reliable, but flexible forming and rational assembly are compromised
Solution Approach 1:
The patent applies dynamics by creating a tiered anchor point system where the upper portion with more anchor points can be selectively activated or deactivated based on the actual concrete pressure conditions. For lower concrete pressures, fewer anchor points in the lower portion may suffice, enabling faster assembly. For higher pressures, the additional upper anchor points provide enhanced reliability. This dynamic configuration allows the anchoring system to adapt to varying load conditions while maintaining operational efficiency.

AI summary
The invention relates to a wall formwork (1) for concrete structures, comprising a basic body (18), an outer face configured as a formwork facing (6), and anchor points in the form of anchor holes (2, 3, 4, 5) for the detachable connection to other wall formworks. It is proposed that, in relation to the horizontal central axis (7) of the wall formwork (1), more anchor points be provided in the upper portion (8) of the wall formwork (1) than in the lower portion (9). Thus, the number of anchor rods to be used can be optimized.
