UV-Curing Injection Mortar for Fast Anchor Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical screw anchors for fixing elements in concrete or brickwork require a long curing time, which is temperature-dependent, limiting the time available for application and adjustment correction.
Innovation Solution
The use of a UV-curing injection mortar with a radiation source positioned within the injection mortar range, allowing for quick curing upon exposure to electromagnetic radiation, such as UV light, from LEDs or optical fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional chemical screw anchors are used, then high firmness is achieved, but curing time becomes very long and temperature-dependent
Solution Approach 1:
The patent replaces the conventional temperature-dependent chemical curing mechanism with a radiation-induced curing mechanism. The chemical composition is designed to cure upon exposure to electromagnetic radiation (UV or visible light) rather than relying solely on thermal energy, thereby substituting a thermally-driven chemical process with a photochemically-driven one. This allows curing to occur independently of ambient temperature conditions.
Solution Approach 2:
The radiation source is positioned within the injection mortar range before the curing process begins, and the chemical composition is formulated to be activated by this pre-positioned radiation source. This preliminary arrangement of the radiation source ensures that curing can be initiated immediately when radiation is applied, eliminating waiting time and enabling on-demand curing at any temperature.
2Strength
If conventional chemical screw anchors with long curing time are used, then high firmness is achieved, but time for application and adjustment correction is limited
Solution Approach 1:
The patent introduces dynamic control over the curing process through the radiation source. The chemical composition remains uncured and adjustable during the application phase, and curing is dynamically initiated only when radiation is applied. This dynamic switching between uncured (adjustable) and cured (fixed) states allows ample time for application and correction without compromising final firmness.
3Adaptability or versatility
If processing times and curing times are made temperature-independent, then application flexibility is improved, but conventional chemical systems cannot achieve this
Solution Approach 1:
The patent substitutes the temperature-dependent thermal curing mechanism with a radiation-based photochemical curing mechanism. This substitution fundamentally changes the curing trigger from thermal energy (temperature) to electromagnetic radiation, thereby achieving temperature-independent processing and curing times while enabling application flexibility across various environmental conditions.
