Adjustable Curtain Wall Anchor With Arcuate Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curtain wall systems face challenges in installation due to as-built conditions deviating from design plans, requiring adjustable anchors that can correct for these deviations.
Innovation Solution
An adjustable curtain wall anchor system featuring a back member with arcuate slotted apertures and vertically-oriented ridges, along with locking washers, allows for angular adjustment and securement to building structures, accommodating variations in as-built conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixed anchors are used to secure curtain walls, then installation precision is improved, but adaptability to as-built condition deviations deteriorates
Solution Approach 1:
The anchor system incorporates an adjustable arm with multiple articulation points that can dynamically change its configuration. The arm includes a base member, intermediate member, and distal member that can articulate relative to each other, allowing the anchor to adapt to various as-built conditions while maintaining secure attachment to both the building structure and curtain wall member
Solution Approach 2:
The anchor system allows for parameter changes in arm length and angular positioning through the articulated joints. The intermediate member can articulate at different angles relative to the base member, and the distal member can articulate relative to the intermediate member, enabling the system to compensate for deviations in building structure dimensions and positions
2Adaptability or versatility
If adjustable mechanisms are added to accommodate as-built deviations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The anchor system is divided into distinct segments: a back member for attachment to the building structure, an adjustable arm with base member, intermediate member, and distal member, and a curtain wall member. This segmentation allows each component to perform its specific function independently while contributing to the overall adjustability and simplicity of the system
3Adaptability or versatility
If multiple articulation points are used for adjustment, then positioning flexibility is improved, but installation time increases
Solution Approach 1:
The anchor system is designed with pre-configured articulation points and connection interfaces that allow for quick assembly. The base member, intermediate member, and distal member are designed to articulate at predetermined angles, enabling installers to rapidly adjust the arm position without complex calculations or multiple adjustment steps

AI summary
A curtain-wall anchor includes a back member having a first arcuate slotted aperture and a second aperture formed therein. The first arcuate slotted aperture receives a first mounting bolt and the second aperture receives a second mounting bolt. A first plurality of vertically-oriented ridges are formed in the back member proximate the first arcuate slotted aperture and the second aperture. A first locking washer is received onto the first mounting bolt. The first locking washer includes a second plurality of vertically-oriented ridges that are complementary to the first plurality of vertically-oriented ridges formed in the back member. The first arcuate slotted aperture facilitates angular adjustment of the back member. Engagement of the second plurality of vertically-oriented ridges with the first plurality of vertically-oriented ridges facilitates securement of the back member in a select angular position.
