Spring-Loaded Furring Strip Fastener for Insulation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing heat insulating materials to concrete walls in buildings are cumbersome and prone to loosening over time, especially during earthquakes, requiring additional fixing plates and failing to provide long-term stability.
Innovation Solution
A furring strip fastening member with a furring strip receiving plate, a rear face plate, and a spring section, along with a female thread section, which allows the furring strip receiving plate to press against the furring strip and the rear face plate to press against the heat insulating material, utilizing a spring reaction for secure fixation and preventing bolt loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate heat insulating material fixing plate is used to fix the heat insulating material to the concrete wall, then the heat insulating material can be fixed, but the structure becomes complex and the fixing plate may loosen over time or during earthquakes
Solution Approach 1:
The patent combines the heat insulating material fixing function and the furring strip fixing function into a single integrated fastening member. The fixing member includes a fixing plate for attaching to the heat insulating material and a furring strip receiving portion for attaching the furring strip, eliminating the need for separate fixing plates and reducing structural complexity while maintaining reliable fixation.
Solution Approach 2:
The fastening member is designed to perform multiple functions: it fixes the heat insulating material to the concrete wall, positions the furring strip at the correct location, and provides spacing between the furring strip and the wall. This multi-functional design simplifies the overall construction system by eliminating the need for separate components for each function.
2Device complexity
If the female thread section is integrally formed with the furring strip receiving plate, then the structure is simple, but the female thread section may come off the receiving plate causing bolt loosening
Solution Approach 1:
The female thread section is nested within a dedicated thread housing portion that is separately formed and then integrated with the furring strip receiving plate. This nested structure provides mechanical reinforcement and prevents the female thread section from detaching, while maintaining relatively simple overall construction.
Solution Approach 2:
The fastening member is divided into distinct functional sections: the furring strip receiving plate, the thread housing portion containing the female thread section, and the fixing plate. This segmentation allows each component to be optimized for its specific function while being assembled into a unified structure that prevents loosening.
3Duration of action of stationary object
If additional heat insulating material fixing plates are used to ensure long-term fixation, then fixing reliability improves, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent integrates the heat insulating material fixing function directly into the main fastening member body, eliminating the need for separate fixing plates. The fixing plate is built-in and works in conjunction with the furring strip receiving portion, simplifying installation to a single operation while ensuring long-term fixation durability.
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 ensures long-term fixation of heat insulating materials without the need for additional fixing plates, maintaining stability during earthquakes and ensuring even siding installation by adjusting the furring strip position based on screwing degree.
Implementation Method 1
The spring section connects the furring strip receiving plate and the rear face plate... the rear face plate can press against the heat insulating material, over long periods of time, on account of the reaction of the spring section

AI summary
A furring strip fastening member comprises a furring strip receiving plate having a through-hole and a female thread section latching section, a rear face plate having a through-hole, a spring section and a female thread section. The spring section connects the furring strip receiving plate and the rear face plate. The female thread section has a through-hole having a thread formed in the inner periphery thereof, and is latched by the female thread section latching sections. In the construction structure for a building, the furring strip fastening member is connected to skeleton wall of building that is formed of concrete wall and a heat insulating material disposed outside the latter, in a state where the female thread section is screwed to the bolt. The furring strip receiving plate presses against the furring strip and the rear face plate presses against the heat insulating material.
