Two-Part Wall Tie With Retainer Hooks For Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for constructing cavity walls with wall ties are cumbersome, as they require workers to bend and fix steel rods, which obstructs the construction process and compromises the structural integrity, especially when dealing with cables and pipes, leading to safety concerns and inefficiencies.
Innovation Solution
A cavity wall system featuring a two-part wall tie with a first fixation system that includes a hook arrangement for retaining cables and pipes, allowing for safer installation and easier construction by reducing the need for bending and providing secure structural connections between wall leaves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a contiguous steel rod wall tie is used to ensure structural strength, then the wall tie can withstand pulling and pushing forces, but it obstructs the construction process and reduces work safety in the cavity
Solution Approach 1:
The wall tie is divided into separate parts: a first fixation system embedded in the inner wall leaf and a second fixation system for the outer wall leaf, replacing the traditional contiguous rod. This segmentation allows workers to install components sequentially without obstructing the cavity space, improving ease of operation while maintaining structural strength through the distributed fixation points.
2Ease of manufacture
If workers hammer nails into wall leaves to fix cables and pipes, then objects can be securely fixed, but the integrity of the wall leaf is compromised
Solution Approach 1:
The wall tie system is designed with multi-functionality: in addition to its primary function of connecting wall leaves, it provides attachment points for fixing cables and pipes. The first and second fixation systems serve dual purposes as both structural connectors and mounting points for utilities, eliminating the need for separate nail-fixing operations that would compromise wall integrity.
3Stability of the object's composition
If a single contiguous wall tie is installed, then structural integrity is achieved, but the construction process becomes cumbersome and time-consuming
Solution Approach 1:
The first fixation system is installed in advance during the construction of the inner wall leaf, before the outer wall leaf is built. This preliminary action allows the wall tie to be positioned and secured early in the process, eliminating the need for bending operations later and streamlining the overall construction sequence, thereby improving productivity while maintaining structural integrity.
4Length of stationary object
If the wall tie protrudes far into the cavity, then it provides adequate connection between wall leaves, but it reduces work safety for workers
Solution Approach 1:
By segmenting the wall tie into separate fixation systems, each component can be optimized for its specific function. The first fixation system protrudes only as much as needed from the inner wall leaf to connect with the second fixation system, minimizing the protruding length into the cavity and reducing safety hazards for workers while still achieving adequate connection between wall leaves.
