Hinge Corner Bracket for Column Formwork
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current column forming systems are inefficient due to the need to disconnect and reconnect rigid corner brackets, and they create sharp 90-degree corner angles that are difficult to fill with concrete and pose safety hazards.
Innovation Solution
A column forming system with a hinge corner bracket that allows for the creation of chamfered corners, enabling easier movement and reconfiguration of the system without the need for disconnection of corner brackets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid corner brackets are used in column forming systems, then structural strength is improved, but the time required for disconnection and reconnection increases
Solution Approach 1:
The corner bracket incorporates a hinge mechanism that enables dynamic movement between fixed and movable states. During concrete pouring, the bracket maintains rigid structural strength; during relocation, the hinge allows the formwork panels to be folded and the bracket to be quickly disconnected and reconnected without full disassembly, thereby reducing time loss while preserving strength during operation.
Solution Approach 2:
The corner bracket is divided into multiple segments connected by hinges, allowing independent movement of formwork panels relative to each other. This segmentation enables the bracket to maintain structural integrity during concrete pouring while facilitating rapid reconfiguration and relocation by allowing panels to be folded independently without complete disconnection.
2Device complexity
If ninety-degree corner angles are created, then structural simplicity is improved, but safety hazards increase due to sharp edges
Solution Approach 1:
The corner bracket incorporates chamfered panels at the corners that create localized beveled edges instead of sharp ninety-degree angles. This local modification maintains the overall simple ninety-degree corner structure while eliminating the harmful sharp edges at specific critical locations, thereby preserving structural simplicity while improving safety.
3Device complexity
If ninety-degree corner angles are created, then structural simplicity is improved, but concrete filling difficulty increases
Solution Approach 1:
Chamfered panels are incorporated at the corner locations to create beveled surfaces that facilitate concrete flow and complete filling. The local chamfer geometry eliminates air pockets and allows concrete to reach all corners effectively, while the rest of the formwork maintains simple ninety-degree angles, thus preserving overall structural simplicity while improving concrete filling ease.
4Object-affected harmful factors
If additional devices are added to create chamfer corners, then safety and concrete filling ease are improved, but device complexity increases
Solution Approach 1:
The chamfer corner creation function is merged into the corner bracket structure itself through integrated chamfered panels. Instead of using separate additional devices attached to the corner brackets, the chamfer geometry is built-in as part of the bracket design, thereby achieving safety and concrete filling improvements without increasing overall device complexity.
Solution Approach 2:
The corner bracket is designed to perform multiple functions: providing structural support during concrete pouring, creating chamfered corners for safety and filling ease, and enabling rapid reconfiguration through hinge movement. This multi-functionality eliminates the need for separate dedicated chamfer devices, maintaining device simplicity while achieving multiple benefits simultaneously.

AI summary
A column forming system for creating chamfer corners and allowing efficient movement from one column location to the next. The column forming system comprises a plurality of formwork panels, a hinge corner bracket moveable between an open and a closed position, and a plurality of corner brackets. The connection of the components allows for the manipulation of the formwork panels relative to one another. A closed position of the hinge corner bracket results in the column forming system defining a column interior.
