Timber-Frame Wall Preassembly with Concrete Infill for Planarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Timber-frame, frame, and post-and-beam constructions often result in non-planar walls due to the linear extension of pillars and struts, and traditional methods are labor-intensive and require drilling or pegging, making it difficult to achieve maximum strength and integrate installations efficiently.
Innovation Solution
A method involving plate-shaped wall structural elements with elongated anchoring parts, filled with a curing compound like concrete, which allows for preassembly on a flat surface, eliminating the need for drilling and pegging, and enabling integrated installations, with screws or other anchoring parts that can be removed after solidification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional timber-frame construction methods are used with linear pillars and struts, then the construction process is labor-intensive requiring drilling and pegging, but the walls cannot achieve planarity
Solution Approach 1:
The invention applies preliminary action by pre-assembling wall segments on a flat surface before final installation. Wall segments are constructed horizontally on a planar base, allowing precise alignment and planarity to be achieved before the segments are lifted and installed vertically in the building. This preassembly eliminates the need for drilling and pegging during traditional construction while ensuring wall planarity is maintained.
2Strength
If wood is used for pillars and struts in post-and-beam construction, then the structure has sufficient strength, but the walls work more strongly (less stable) compared to solid houses
Solution Approach 1:
The invention uses composite materials by combining wood pillars and struts with concrete infill panels. The wooden framework provides structural strength and flexibility, while the concrete panels filled between the framework elements add mass and stability to the walls. This composite construction allows the walls to benefit from both the strength of wood and the stability of concrete, resolving the contradiction between framework strength and wall stability.
3Productivity
If a framework shell is built first and then paneled, then the structure is easy to assemble, but drilling and pegging are required which are labor-intensive
Solution Approach 1:
The invention applies preliminary action by pre-assembling complete wall segments on a flat surface before final installation. During this preassembly phase, all necessary connections and panelings are completed while the segment is accessible and stable. This eliminates the need for drilling and pegging operations that would be required if paneling were done after framework installation, significantly reducing labor intensity while maintaining assembly speed.
Solution Approach 2:
The invention inverts the traditional construction sequence by building wall segments horizontally on a flat surface first, then installing them vertically as complete units. This reversal allows all connections and panelings to be made while the segment is in a stable, accessible position, eliminating the need for subsequent drilling and pegging operations that would be required in the traditional vertical assembly approach.
4Device complexity
If installations are integrated after wall construction, then the wall structure is simple, but installing power, water, and heating elements requires additional drilling and modification
Solution Approach 1:
The invention applies preliminary action by integrating installations during the preassembly phase of wall segment construction. Electrical conduits, water pipes, and heating elements are routed and positioned within the wall segment framework before the segment is finalized and installed in the building. This preliminary integration eliminates the need for additional drilling and modification after wall construction, reducing labor effort while maintaining structural simplicity.
