Concrete Anchor Holder with Split Nut Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete anchor systems face challenges in efficiently positioning and securing anchors on concrete form surfaces before pouring concrete, leading to issues with concrete slurry infiltration and post-installation load support.
Innovation Solution
A concrete anchor assembly comprising a holder with a base and sleeve portion, vertical openings for nails, and an anchor body with a rod and head portion, featuring internal and external threads for load support, along with a split nut and spring mechanism for sealing and adjustable thread sizes, ensures secure embedding and post-installation load attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional concrete anchor systems are used, then the anchors can be embedded in concrete, but the positioning and securing of anchors on concrete form surfaces is inefficient and allows concrete slurry infiltration
Solution Approach 1:
The holder is divided into multiple functional segments: a base portion for positioning, a sleeve portion for anchor retention, and post portions with vertical openings for nail insertion. This segmentation allows each component to perform its specific function efficiently while working together as an integrated system.
Solution Approach 2:
The holder is designed to be positioned and secured to the concrete form surface before the concrete is poured. The vertical openings receive nails that are inserted in advance, creating a pre-assembled unit that is then attached to the form. This preliminary action ensures proper anchor positioning before the concrete sets, preventing slurry infiltration and ensuring secure embedding.
2Measurement precision
If anchors are positioned before concrete pouring, then proper placement is achieved, but concrete slurry can still infiltrate and compromise the anchor-holding structure
Solution Approach 1:
The anchor body with head portion is nested within the holder's sleeve portion, creating a nested structure where the anchor is protected by the holder. The post portions with vertical openings provide additional nested layers for nail insertion and securing. This nested arrangement prevents concrete slurry from reaching and compromising the anchor-holding interface.
Solution Approach 2:
The holder acts as an intermediary component between the concrete form surface and the anchor body. It provides a protective barrier that prevents concrete slurry from infiltrating the critical interface where the anchor meets the form. The holder's structural design includes features that block slurry pathways while allowing proper load transfer.
3Ease of manufacture
If a simple holder design is used, then manufacturing is easier, but the holder cannot provide adequate sealing and load support functionality
Solution Approach 1:
The holder is designed as a multi-functional component that simultaneously performs positioning, sealing, and load support functions. The base portion provides positioning and sealing against the form surface, the sleeve portion retains the anchor body and distributes loads, and the post portions with vertical openings provide structural support and additional sealing. This universal design consolidates multiple functions into a single manufacturable component.
Solution Approach 2:
The holder and anchor assembly utilizes composite construction with different materials optimized for specific functions. The holder may use materials with properties suited for form surface contact and sealing, while the anchor body uses materials optimized for load bearing and concrete embedding. This composite approach allows each component to be manufactured for its specific purpose while working together to provide overall reliability.
4Ease of manufacture
If fixed thread size anchors are used, then manufacturing is simplified, but adaptability to different load requirements is limited
Solution Approach 1:
The anchor system incorporates adjustable or selectable thread sizes to accommodate different load requirements. Rather than being fixed, the thread configuration can be changed or selected based on the specific application needs. This dynamic capability allows the same basic anchor design to serve multiple load classes while maintaining manufacturing efficiency through standardized components.
Solution Approach 2:
The anchor body is designed with variable parameters, particularly the thread size and configuration, which can be changed to match different load requirements. This parameter variability allows a single anchor family to serve multiple purposes - from light-duty to heavy-duty applications - by simply changing the thread specifications while maintaining the same basic structural design and manufacturing process.
