Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing early-stripping formwork systems for construction, particularly those used in concreting of beams, slabs, and columns, face challenges such as high costs, inefficiencies, and difficulties in adaptation to domestic building structures, requiring extensive resources and labor due to complex designs and rigid structures that complicate transportation and storage.
Innovation Solution
A detachable combined early-stripping formwork system comprising standard formworks with L-shaped corners, telescopic props, and filler beams, which can be easily disassembled for efficient storage and transportation, reducing costs and labor intensity while maintaining structural integrity and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the formwork frame is constructed with welded rigid construction, then the structural strength and stability are improved, but the storage and transportation convenience deteriorates due to large occupation space and difficulty in assembly/disassembly
Solution Approach 1:
The formwork frame is divided into multiple detachable components including corner posts, horizontal beams, and vertical beams that can be separated and reassembled. This segmentation allows the structure to be disassembled for compact storage and easy transportation while maintaining structural integrity when assembled, directly resolving the contradiction between strength and ease of operation.
Solution Approach 2:
The detachable components are designed with complementary connection structures that merge seamlessly when assembled, creating a rigid overall framework. The corner posts, horizontal beams, and vertical beams combine to form a stable structure that provides the necessary strength while allowing for easy assembly and disassembly for storage and transportation purposes.
2Adaptability or versatility
If multiple specifications of filler panels and secondary filler panels are manufactured, then the adaptability to different structural requirements is improved, but the manufacturing cost and storage complexity increase
Solution Approach 1:
The filler panels are designed with a universal structure that can accommodate different structural requirements through adjustable positioning and configuration. The standardized design allows the same panel type to serve multiple functions in different locations, eliminating the need for multiple specifications and reducing manufacturing complexity while maintaining adaptability.
3Productivity
If a large amount of formworks and workers are equipped, then the construction speed and productivity are improved, but the construction cost increases greatly
Solution Approach 1:
The formwork system incorporates dynamic early-stripping mechanisms that allow for rapid removal and reuse of formwork components. The telescopic props and detachable structures enable quick assembly and disassembly, increasing the number of times formwork can be reused and thereby reducing the total quantity of formwork materials needed while maintaining high construction productivity.
Solution Approach 2:
The early-stripping mechanism enables the formwork to be removed and recovered for reuse in subsequent construction phases. The detachable design facilitates efficient recovery and redistribution of formwork components, reducing the need for continuous supply of new formwork materials and thereby lowering construction costs while maintaining high productivity.

AI summary
An early-stripping formwork system for concreting of constructions comprising beams, slab and columns comprises several rectangular standard formworks (1), props with multiple early-stripping support mechanisms (2), several filler beams (3) and filler panels. The standard formwork (1) consists of a panel (11) and a formwork frame (12), and the formwork frame (12) is provided with L-shaped corners (121) at its four corners. Each of the early-stripping prop (2) consists of an upper support inner tube (21) and a lower support tube (22) which form a telescopic connection, a rectangular head plate (23) is disposed at the top end of the upper support inner tube (21), one corner of the head plate (23) fits an internal corner of any one of the L-shaped corners (121) on the formwork frame (12). A load-releasing mechanism (24) is connected between the upper support inner tube (21) and the lower support outer tube (22). An early stripping mechanism (25) for early stripping of the standard formwork (1) is disposed on the upper support inner tube (21), short posts (251) for supporting the formwork frame (12) are disposed at four corners of the early stripping mechanism (25), and a structure for preventing the formwork frame (12) from slipping outwards is formed between the short post (251) and the L-shaped corner (121). The formwork frame (12), the filler panel, the filler beam (3), and a bridge beam (4) may be all in a detachable combined structure. In the formwork system, transport and storage of the formwork are convenient, and manufacturing cost is reduced.
