Prefabricated Structure Tensioning Rod Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current prefabricated structure assembly methods are inefficient, costly, and unreliable due to the need for extensive screwing or gluing, which leads to structural instability and difficulty in disassembly, especially when exposed to bad weather, and do not effectively manage slack or allow for easy removal.
Innovation Solution
A prefabricated structure featuring a frame with posts that use traction means, such as tie bars and screw nuts, to compact and block panels, eliminating the need for direct mechanical connections between panels and posts, allowing for efficient assembly, easy disassembly, and slack management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If panels are fixed to posts using screws or glues, then the structure achieves initial stability, but the assembly time increases significantly and disassembly becomes difficult or impossible
Solution Approach 1:
The structure is divided into modular panels and posts that can be independently assembled and disassembled. Each panel can be separately fixed to posts using the tensioning rod mechanism, allowing rapid assembly without time-consuming adhesive applications or extensive screwing operations.
Solution Approach 2:
The tensioning rod system provides dynamic adjustment capability, allowing the structure to be assembled and disassembled easily. The rods can be tensioned to secure panels during assembly, and relaxed or removed for disassembly, eliminating the permanent fixation issues with screws and glues.
2Strength
If multiple screws are used to fix panels to posts, then the structure achieves firm connection, but the reliability decreases due to screw blunting and structural damage from numerous holes
Solution Approach 1:
The invention extracts the connection function from multiple discrete screws and replaces it with a single tensioning rod per panel that applies distributed force through the panel's reinforcement elements. This reduces the number of penetration points in the panel, minimizing structural damage and maintaining reliability.
Solution Approach 2:
Reinforcement elements (such as metal strips or wooden battens) are introduced as intermediaries between the tensioning rod and the panel. These intermediaries distribute the clamping force across multiple points on the panel without requiring multiple holes through the panel itself, thus maintaining panel integrity and reliability.
3Strength
If glue is used to fix panels to posts, then the structure achieves firm connection, but disassembly becomes entirely impossible and time consumption increases
Solution Approach 1:
The tensioning rod system provides dynamic, reversible connection. Panels can be securely fixed during assembly by tightening the rods, and easily released for disassembly by loosening or removing the rods, eliminating the permanent bonding characteristic of glue while maintaining connection strength.
4Stability of the object's composition
If groove-and-tongue joints are used to connect panels, then the structure achieves stability without posts and screws, but the manufacturing cost increases due to expensive specialized machinery
Solution Approach 1:
The connection function is segmented between the tensioning rods (providing the pulling force) and the reinforcement elements on the panels (providing the attachment points). This allows using standard drilling and reinforcement techniques rather than expensive groove-and-tongue machining equipment.
5Stability of the object's composition
If groove-and-tongue joints are used to connect panels, then the structure achieves stability without extensive fastening, but the junction points become exposed to weathering and prone to breakage
Solution Approach 1:
Reinforcement elements serve as intermediaries that protect the connection points between panels and posts. These reinforcement strips cover the attachment areas, shielding them from direct weather exposure while providing secure attachment points for the tensioning rods.

AI summary
The present invention refers to a base structure for the realization of prefabricated in general comprising a frame (1) constituted by at least two posts (2, 2') opposed to each other. One or a plurality of panels (3) are framed within the posts in order to realize the base structure. In particular, according to the invention, the posts expects at predetermined heights h couples of holes (10) coaxial to each other to allow the insertion for each couple of tie bars (16) able to apply a reciprocal approaching action of the posts to block the panels comprised between them.
