Formwork Panel Assembly with Pre-mounted Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork systems for building and public works are complex to assemble and adjust before concrete pouring, and their manufacturing process is not optimized for efficiency.
Innovation Solution
A formwork system with pre-mounted standard and complementary screws and nuts along the edges of panels, along with adjustable strips for securing panels side-by-side and face-to-face, simplifies assembly and adjustment by allowing for variable distances and easy alignment, using oblong openings and articulated lifting means for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional formwork assembly methods are used, then formwork panels can be secured together, but the assembly and adjustment operations become complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-mounting screws and nuts at specific locations on formwork panels before assembly. The fastening elements are positioned in advance on the panels, allowing for rapid connection when panels are brought together, eliminating the need for on-site drilling or complex assembly operations.
Solution Approach 2:
The patent segments the fastening system into separate components: screws mounted on one panel and nuts mounted on the opposite panel, with corresponding fastening elements on connecting strips. This segmentation allows each component to be pre-positioned independently, simplifying the overall assembly process when panels are joined.
2Ease of manufacture
If traditional formwork assembly methods are used, then formwork panels can be secured together, but the manufacturing process becomes less efficient
Solution Approach 1:
The patent applies preliminary action by pre-mounting screws and nuts at specific locations on formwork panels before assembly. The fastening elements are positioned in advance on the panels, allowing for rapid connection when panels are brought together, eliminating the need for on-site drilling or complex assembly operations.
Solution Approach 2:
The patent creates universal fastening strips that can be used across different panel configurations and dimensions. These strips with pre-mounted fastening elements can accommodate various panel sizes and arrangements, making the same component set applicable to multiple manufacturing scenarios and reducing the need for custom assembly procedures.
3Adaptability or versatility
If fixed spacing between screw and nut elements is used, then assembly is simplified, but adaptability to different dimensions is reduced
Solution Approach 1:
The patent applies dynamics by making the spacing between fastening elements adjustable rather than fixed. The strips can be configured with variable distances between screw and nut elements, allowing adaptation to different panel dimensions and assembly requirements while maintaining a relatively simple overall mechanism.
Solution Approach 2:
The patent changes the parameter of spacing between fastening elements from fixed to variable. By allowing adjustment of this critical parameter, the system becomes adaptable to different panel sizes and configurations without requiring fundamentally different assembly mechanisms for each dimension.

AI summary
The system consists of a series of panels (1) of standard dimensions (e.g. 2520 mm high by 2400 mm wide) that are joined together edge to edge or face to face by pre-assembled matching nut and bolt assemblies (12). The nuts (40) are located along one edge of a panel, and the bolts (50) along the opposite edge, allowing a number of panels to be joined together to achieve a required length and supported by frames or struts. The upper edge of each panel has fittings (11) for lifting hooks, and the lower edge has levelling supports (13).
