Hinged Construction Form for One-Sided Concrete Hole Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forms are unable to seal and fill holes in concrete walls when one side cannot be accessed, as they cannot be journaled through the hole and provide necessary blockage for pouring concrete.
Innovation Solution
A form with a hingedly coupled first and second portion, movable between collapsed and deployed positions, allowing insertion through a hole and sealing in the deployed position, comprising a semi-annular lower section and a planar upper section to block and fill openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a form is used to seal a hole in a concrete wall, then the hole can be blocked for pouring concrete, but the form cannot be inserted through the hole if one side is inaccessible
Solution Approach 1:
The form is divided into a first portion and a second portion that can be inserted through the hole separately. Each portion has a semi-annular lower section and a planar upper section, allowing them to pass through the hole in sequence and then assemble to create the sealing structure.
Solution Approach 2:
The form includes movable connections between the first and second portions, allowing the structure to transition from a collapsed insertion state to an expanded sealing state. This dynamic configuration enables the form to fit through the hole while then expanding to block it effectively.
2Reliability
If a rigid form structure is used to block the hole, then sealing effectiveness is improved, but the form cannot be passed through the hole
Solution Approach 1:
The form is designed with movable connections that allow it to collapse into a compact configuration for insertion through the hole, then expand to a rigid sealing configuration once positioned. This dynamic transformation resolves the conflict between needing a large rigid structure for sealing and a small flexible structure for insertion.
Solution Approach 2:
The first and second portions are designed to nest within each other during insertion, with one portion passing through the hole while the other follows. This nesting approach allows the complete form structure to be transported through the hole in a compact state while maintaining the full sealing capability when deployed.
3Reliability
If the form is designed to seal the hole effectively, then concrete pouring is enabled, but the form cannot be retrieved or repositioned
Solution Approach 1:
The form is segmented into removable portions that can be inserted through the hole and then assembled on the accessible side. This segmentation allows the form to be positioned and secured effectively for pouring while also enabling retrieval or repositioning by disassembling the portions from the accessible side.

AI summary
A construction form utilized to seal an opening so as to facilitate pouring of concrete or other pourable material into a hole or pipe. The invention includes a body wherein the body is comprised of a first portion and a second portion. The first portion and second portion are movably coupled facilitating movement of the body between a collapsed position and a deployed position. The first portion and second portion are identically constructed each having a lower section integrally formed with an upper section. The lower sections are semi-annular in shape having a bottom surface. A hinge member is operably coupled to bottom surface of the lower section of the first portion and second portion of the body. A pull member is attached to the bottom surface of one of the two lower sections and is operable to facilitate moving the body to its deployed position.
