Disposable Formwork Blocks for Concrete Wall Columns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of walls with concrete supports is labor-intensive and time-consuming, and existing formwork devices may not always ensure optimal formwork and column properties due to processing issues.
Innovation Solution
A formwork device comprising special formwork elements with holes that pass through and connect to the wall sections, allowing for easier integration and alignment of concrete supports, using wall connectors to secure the formwork elements to the masonry blocks, and allowing the formwork elements to be designed in any shape or size, with reinforcement for stability and thermal insulation properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wooden formwork with integrated reinforcement is used for constructing concrete columns, then the concrete columns can be built with proper reinforcement, but the construction process becomes extremely time-consuming and labor-intensive
Solution Approach 1:
The patent uses disposable formwork blocks made of inexpensive materials that are removed after concrete pouring. These blocks serve their formwork function temporarily and are then discarded, eliminating the need for complex reusable formwork systems and significantly reducing construction time while maintaining concrete column quality
Solution Approach 2:
The wall construction is divided into modular segments where formwork blocks are placed at specific intervals to create concrete columns. This segmentation allows parallel construction of multiple wall sections simultaneously, improving overall productivity while ensuring each concrete column meets quality requirements
2Stability of the object's composition
If concrete columns are built first with traditional formwork, then the wall construction can proceed, but additional leveling elements are required to compensate for thickness differences
Solution Approach 1:
The formwork blocks serve multiple functions: they act as formwork for concrete columns, provide the necessary thickness to match the wall structure, and eliminate the need for separate leveling elements. This multi-functionality reduces device complexity while maintaining wall structural stability
3Productivity
If formwork blocks are used to speed up construction, then wall construction becomes faster and easier, but processing issues may result in suboptimal formwork and column properties
Solution Approach 1:
The patent specifies precise geometric parameters for formwork blocks including dimensions, tolerances, and surface finish requirements. By controlling these parameters during manufacturing, the system achieves both high construction speed and dimensional accuracy of concrete columns, preventing processing issues

AI summary
A formwork device for the production of concrete columns, in particular for the production of vertical concrete columns forming parts of a wall, is described. The described formwork device is characterized in that it is formed by one or more superimposed formwork elements, which are traversed by a vertical recess having a cross-section corresponding to the cross-section of the concrete column, and which has holes on at least one of its sides facing the wall sections not formed by formwork elements. These holes completely pass through the formwork element wall containing the holes and open into the vertical recess.
