Prefabricated Wall Panel Tensioning for Binderless Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prefabricated buildings have lower mechanical performance and longer construction times due to the use of binders like cement mortars, which require long drying times, limiting the construction of multi-storey structures.
Innovation Solution
A prefabricated wall construction kit with tubular elements and reinforcing components that allow for the assembly of wall panels without binders, using a tensioning member to increase mechanical performance and speed up construction by connecting panels to load-bearing beams and structural elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If binders like cement mortars are used to assemble prefabricated panels, then the panels can be connected and form load-bearing structures, but the construction time increases due to long drying times
Solution Approach 1:
The invention extracts and eliminates the binder (cement mortar) from the assembly process. Instead of using binders to connect panels, the patent employs direct mechanical connections through tubular elements with reinforcing bars that pass through the panels and are secured with nuts and washers, completely removing the drying time requirement associated with binders
Solution Approach 2:
The invention replaces the chemical bonding system (binder-based connection) with a mechanical connection system. The tubular elements containing reinforcing bars, secured with nuts and washers, provide a purely mechanical connection that achieves structural strength without requiring chemical drying processes
2Strength
If traditional binder-based assembly is used for prefabricated panels, then the panels can be connected, but the vertical extension and mechanical performance of the building is limited
Solution Approach 1:
The tubular elements with reinforcing bars are pre-installed within the panels during manufacturing. This preliminary action allows the connection system to be ready for assembly, enabling stronger and taller structures to be built by simply connecting the pre-prepared panels through the tubular elements without requiring additional on-site binder application and drying time
Solution Approach 2:
The invention uses composite construction by combining panels with integrated tubular elements containing reinforcing bars. This composite system creates a unified load-bearing structure where the panel, tubular element, and reinforcing bar work together as a single unit, enabling greater vertical extension and mechanical performance
3Ease of manufacture
If binders are used to connect building components, then the components can adhere to form the framework, but the construction process becomes slower due to required drying times
Solution Approach 1:
The invention removes the binder from the assembly process entirely. The tubular elements with reinforcing bars and nuts provide a binderless connection system that allows panels to be assembled and connected immediately without waiting for drying, thereby maintaining ease of manufacture while dramatically improving construction speed
Solution Approach 2:
The mechanical connection system allows for continuous assembly without interruption for drying. Panels can be connected as they are assembled, enabling continuous productive action throughout the construction process rather than requiring停顿 for binder drying
