Prefabricated Concrete Panel Segmentation for Safe Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods using prefabricated concrete panels for load-bearing walls and floors face challenges such as specific dimensions, installation safety, aesthetic limitations, and increased labor and time due to manual joint production and shoring requirements, particularly in collective housing.
Innovation Solution
The use of prefabricated panels composed of superimposed layers of poured concrete, insulation, and cast concrete, arranged in a lying position with specific panel types for walls and floors, allowing for reduced panel specificity, safer handling, and elimination of shoring needs, along with integrated insulation and decorative finishes, enabling faster and more aesthetically pleasing installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If panels are used at storey height, then construction speed is improved, but installation safety deteriorates due to risk of tipping during handling
Solution Approach 1:
The wall structure is segmented into multiple horizontal levels (first level with lower panels, second level with median panels, third level with upper panels) rather than using single large storey-height panels. This segmentation reduces the size and weight of individual panels, eliminating tipping risks during handling while maintaining construction speed through systematic assembly of smaller units
Solution Approach 2:
The invention transitions from vertical stacking of large panels to horizontal arrangement of smaller panels across multiple levels. Panels are arranged on edge in the lying position across three superimposed levels, changing the dimensional organization from vertical dominance to a distributed horizontal-vertical hybrid structure that improves safety
2Productivity
If panels are used at storey height, then construction efficiency is improved, but device complexity increases due to need for shoring
Solution Approach 1:
Dividing the wall into three levels with smaller panels eliminates the need for shoring support that would be required for large storey-height panels. Each level can be independently supported and assembled without requiring complex temporary shoring structures
Solution Approach 2:
Panels are pre-assembled in groups of three levels with integrated guidance systems (rebate and key) before final installation. This preliminary organization of panels into manageable units simplifies the on-site assembly process and eliminates the need for complex shoring during installation
3Adaptability or versatility
If conventional construction methods are used, then aesthetic flexibility is maintained, but labor quantity and construction duration increase
Solution Approach 1:
Multiple functions are merged into single panel units: insulation is integrated within the panel structure (second layer of plate insulation sandwiched between concrete layers), finishes are pre-applied during manufacturing, and structural and aesthetic functions are combined. This eliminates separate manual operations for insulation installation, finishing, and joint production, dramatically reducing labor and time while maintaining aesthetic flexibility through pre-fabricated variations
Solution Approach 2:
All aesthetic and functional elements (insulation, finishes, joint configurations) are prepared in advance during panel manufacturing. Panels are produced with integrated insulation layers, pre-applied exterior finishes, and configured joint systems, eliminating the need for manual production of these elements on-site and reducing construction duration
4Stability of the object's composition
If continuous vertical joints are used on floor height, then structural continuity is improved, but aesthetic quality deteriorates
Solution Approach 1:
The continuous vertical joint is segmented by introducing horizontal joints at each level. Panels are arranged in three superimposed levels with horizontal joints separating them, breaking the visual continuity of vertical joints and improving aesthetics while maintaining structural integrity through proper joint detailing and connection systems
Solution Approach 2:
The joint configuration transitions from purely vertical continuity to a multi-level horizontal-vertical joint pattern. By arranging panels on edge in the lying position across three levels, the structure introduces horizontal joint elements that interrupt vertical joint lines, creating a more aesthetically pleasing pattern while preserving structural continuity through engineered connections

AI summary
The construction has pre-fabricated concrete panels (12) constituted by superposition of a first poured concrete layer, a second board type insulation layer and a third poured concrete layer. The panels are arranged into three superimposed levels that include juxtaposed skirting type lower panels (1), for the first level, resting on a floor, backboard type medial panels (2), for the second level, resting on the lower panels and juxtaposed lintel type upper panels (3), for the third level, resting on the medial panels. The panels comprise metallic reinforcing frame and metallic reinforcing meshes. An independent claim is also included for a panel fabricating mold comprising a skin made of elastomer material.
