Bendable Arm Core Form Device for Concrete Slab Renovation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for filling core holes in concrete slabs during renovation require extensive effort and expense to secure forms to the bottom of the slab, especially when the space below is occupied.
Innovation Solution
A core form device featuring a circular plate with bendable arms that can be bent to form a core form, allowing for easy insertion into core holes and filling without needing to secure forms to the bottom of the slab, using a circular plate with a diameter less than the core hole and arms that can accommodate various sizes and angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional plates are secured to the bottom of core holes to form concrete forms, then the core holes can be filled, but extensive effort and expense are required to access and work in the space below the slab
Solution Approach 1:
Instead of securing plates from below as in conventional methods, the invention inverts the approach by inserting the core form device from above into the core hole. The device is pushed through the slab surface and expanded within the hole, eliminating the need to access the space below the slab entirely.
Solution Approach 2:
The core form device employs dynamic arms that can change position and configuration. The arms are initially collapsed or retracted for easy insertion into the core hole, then expanded outward to form the concrete form. This dynamic transformation allows the device to adapt from a compact insertion state to an expanded forming state without requiring access from below.
2Ease of operation
If plates are secured to the bottom of the slab to create forms, then concrete can be poured, but furniture and items in the space below must be moved and covered
Solution Approach 1:
The invention extracts the form construction operation from the space below the slab and relocates it to the space above. By inserting and expanding the core form device from the top surface, the entire form construction process occurs in the accessible space above the slab, leaving the space below undisturbed and eliminating the need to move or protect furniture and items there.
Solution Approach 2:
The core form device is self-contained and self-expanding. Once inserted into the core hole from above, the device autonomously expands its arms to form the concrete form without requiring external assistance from below. The device serves itself by transforming from a compact insertion configuration to an expanded forming configuration entirely from the top side.
3Productivity
If conventional forms are used requiring access to the bottom of the slab, then core holes can be filled, but extensive preparation and cleanup effort is required
Solution Approach 1:
The core form device segments the renovation process into distinct phases: insertion from above, expansion within the hole, concrete pouring, and removal. This segmentation allows each phase to be performed independently from the top surface, eliminating the need for continuous access to the space below and reducing overall renovation effort and expense.
