Foundation Anchor Support Plate Fixing to Prevent Flexing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In the construction of building foundations without rising portions, anchors are supported by support plates or poles fixed to formwork, which can flex due to the weight of the anchors, leading to reduced position accuracy.

Innovation Solution

An anchor support system comprising a support plate with spacers and fixing jigs that secure the support plate to the formwork, using screws and arms to limit flexing and ensure accurate positioning of anchors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the support plate is fixed to the formwork only using a screw, then the device complexity is reduced, but the support plate flexes due to the weight of the anchors, lowering the position accuracy

Engineering Contradiction:

Improvefixing structureVSAvoidposition accuracy of anchors

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The support plate is divided into multiple segments (first support plate and second support plate) that are connected through the fixing jig. This segmentation allows each segment to be independently supported, reducing flexing while maintaining overall structural integrity and positioning accuracy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing jig extends in the width direction of the support plate, providing support not just at the ends but also at intermediate positions. This dimensional extension of the fixing structure prevents flexing without significantly increasing overall device complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If the support plate is made more rigid to prevent flexing, then the position accuracy of anchors is improved, but the device complexity and weight increase

Engineering Contradiction:

Improveposition accuracy of anchorsVSAvoidsupport plate structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

Instead of making the entire support plate more rigid, the plate is segmented and supported at multiple points by the fixing jig. This approach maintains position accuracy through distributed support rather than increasing the rigidity of the support plate itself.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing jig acts as an intermediary structure between the formwork and the support plate. It provides the necessary support to prevent flexing without requiring the support plate itself to be made more complex or rigid.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If multiple fixing points are added to the support plate, then the position accuracy is improved, but the ease of manufacture decreases

Engineering Contradiction:

Improveposition accuracy of anchorsVSAvoidsupport plate assembly

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The fixing jig combines multiple fixing functions (supporting both the first and second support plates) into a single integrated component. This merging approach achieves multiple fixation points without proportionally increasing manufacturing complexity, as the fixing jig is designed as a unified structure.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

This anchor support tool supports an anchor provided in a foundation, the anchor support tool comprising: a support plate having at least one support part for supporting an anchor; a spacer for positioning the support plate with respect to a form of the foundation in the height direction; and a fixing jig for fixing the support plate to the form. The fixing jig supports the support plate while the support plate is disposed above the form with the spacer therebetween.
