Wall Plug with Chemical Anchoring and Thermal Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wall plugs fail to securely anchor objects on masonry walls with insulating layers, as they rely on the masonry structure rather than the insulating material, leading to inefficient heat dispersion and installation complexities.
Innovation Solution
A wall plug with a cylindrical metal stem and radial holes, combined with a rigid plastic sheath and chemical anchoring agent, allows for direct fixation into the masonry structure without expansion plugs, creating a thermal barrier and ensuring secure anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional wall plug with a long threaded stem is used to anchor objects on masonry walls with insulating layers, then secure anchoring to the masonry structure is achieved, but heat loss through the insulating layer increases due to the stem bypassing the insulation
Solution Approach 1:
The patent introduces a chemical anchoring agent as an intermediary substance that fills the space between the wall plug stem and the insulating layer. This agent creates a thermal barrier that prevents heat conduction along the stem while maintaining the mechanical anchoring function. The chemical agent acts as a mediator that decouples the thermal and mechanical functions, allowing the stem to anchor securely without creating a thermal bridge through the insulation.
2Reliability
If a traditional expansion plug system is used, then secure anchoring is achieved, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple functions into a single integrated wall plug device. The plug integrates the anchoring stem, the chemical anchoring agent delivery system, and the insulating barrier function into one component. This eliminates the need for separate expansion plugs, anchors, and insulation materials, simplifying both the device structure and the installation process while maintaining secure anchoring to the masonry structure.
3Reliability
If a traditional expansion plug system is used, then secure anchoring is achieved, but installation time and cost increase
Solution Approach 1:
The chemical anchoring agent is pre-loaded into the wall plug stem during manufacturing, eliminating the need for separate mixing and application steps during installation. The plug is designed to deliver the anchoring agent automatically upon insertion into the wall, performing the anchoring action in advance and during a single installation step. This preliminary preparation of the anchoring agent significantly reduces installation time and labor costs while ensuring consistent anchoring strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables rapid, cost-effective, and secure installation on masonry walls with insulating layers, preventing heat loss and supporting heavy objects by using a chemical anchoring agent to firmly embed the plug into the masonry structure.
Implementation Method 1
it is sufficient to inject a suitable amount of chemical anchoring agent (actually a sort of fluid gluing resin) into said hole. Then the new wall plug of the invention is inserted into said hole, waiting for the anchoring agent to set, incorporating and fixing it rigidly in the bearing masonry structure.
Implementation Method 2
such a wall plug is covered at the back end with a rigid sheath of plastic materials adapted to be placed inside the insulating material of the installation wall once the installation of the wall plug has been completed... such a position of said sheath of plastic materials creates a thermal barrier along the bearing metal rod and eliminates dangerous heat losses through the hole that houses the rod and passes through the insulating layer.
