Compressible Insert Mounting Rail for Concrete Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation channels in construction engineering fail to effectively absorb large transverse forces without fracturing the concrete due to the propagation of fissures, leading to a fault block that is too small and results in early failure.
Innovation Solution
An installation channel with a compressible, elastic insert attached to the support profile, which redirects forces into deeper layers of the concrete, preventing direct contact and force transmission, and featuring inclined legs to further distribute loads, thereby increasing the fault block volume and absorption capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the installation channel is embedded directly into concrete with the support profile in direct contact with the curable construction material, then the anchoring is simple and direct, but the fault block volume is small and large transverse forces cause early failure
Solution Approach 1:
A compressible insert is introduced as an intermediary element between the support profile and the curable construction material. This insert prevents direct contact and force transmission at the embedding area, redirecting forces into deeper layers of the concrete to create a larger fault block volume, thereby increasing load-bearing capacity without complicating the overall structure
Solution Approach 2:
The compressible insert changes the mechanical parameters at the embedding area by providing compliance and elasticity. This modifies how forces are transmitted into the concrete, distributing them over a larger volume and preventing localized stress concentrations that would cause early failure
2Strength
If the support profile is in direct contact with the curable construction material at the embedding area, then force transmission is direct and simple, but transverse forces propagate fissures and create small fault blocks leading to early failure
Solution Approach 1:
The compressible insert acts as a mediator that intercepts transverse forces before they can propagate fissures in the concrete. By absorbing and redistributing these forces, it prevents the formation of small fault blocks and maintains reliability under transverse loading conditions
Solution Approach 2:
The compressible insert provides beforehand cushioning by being pre-installed at the embedding area. It cushions against transverse forces before they can cause damage, absorbing the impact and redirecting forces into deeper concrete layers where they can be better distributed
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 allows for the absorption of larger forces and transverse loads without concrete failure, enhancing the load-bearing capacity and increasing the fault block volume by redirecting forces into deeper concrete layers.
Implementation Method 1
a preferably compressible insert is fastened to the outside of the support profile at the embedding area
Implementation Method 2
the insert is preferably arranged on an end section of the support profile in the vicinity of the outer area, so that as a result, the forces that are to be conveyed into the construction material, especially transverse forces, can be conveyed outside of the surface of the construction material into the curable construction material in deeper layers

AI summary
In an installation channel to be embedded into a curable construction material, e.g. concrete, having a support profile and preferably an attachment for attaching at least one add-on part to the installation channel, so that the outside of the support profile has a direct connection to the curable construction material at an embedding area, a potential fault block should be large so that large forces can be absorbed by the installation channel.A compressible insert is fastened to the outside of the support profile at the embedding area, so that part of the outside of the support profile is not in direct contact with the curable construction material at the embedding area.
