Foundation Heat Insulation Attachment Structure for Easy Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment structures for heat insulating materials on foundations are cumbersome and difficult to remove, requiring complex and labor-intensive processes, which complicates inspections and maintenance.
Innovation Solution
An attachment structure comprising a maintaining member that keeps the heat insulating material close to the foundation wall and a retaining member that positions and secures the maintaining member, allowing for easy sliding and non-detachable retention, facilitating simple attachment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat insulating material is fastened using U-shaped nail-like fasteners to prevent easy detachment, then the reliability of attachment is improved, but the ease of operation deteriorates because work is required to remove the nail-like fasteners
Solution Approach 1:
The retaining member is divided into an upper retaining portion and a lower retaining portion that can be separated. The upper retaining portion can be detached from the maintaining member, allowing the heat insulating material to be removed easily while the lower retaining portion remains attached to the foundation, thus resolving the contradiction between secure attachment and easy removal.
2Reliability
If an attachment hole is bored in the foundation and a plate member with a rod-shaped member is used to sandwich the heat insulating material, then the attachment reliability is improved, but the device complexity increases due to the need to bore holes and the complicated attachment/removal work
Solution Approach 1:
The rod-shaped member that fits into the foundation hole is extracted from the plate member and integrated into the maintaining member instead. This simplifies the overall structure by eliminating the separate plate member and rod-shaped member combination, reducing device complexity while maintaining attachment reliability through the retaining member's upper and lower retaining portions.
3Reliability
If the heat insulating material is affixed to the wall surface, then the attachment reliability is improved, but the ease of operation deteriorates because it becomes impossible to check between the foundation and the heat insulating material or inside the heat insulating material
Solution Approach 1:
The attachment structure transitions from a fixed affixed state to a detachable state. The maintaining member can be removed from the upper retaining portion, allowing dynamic access for inspection between the foundation and heat insulating material, while the heat insulating material remains securely attached when in place, thus resolving the contradiction between reliable attachment and inspection accessibility.

AI summary
[Summary][Problem] To provide an attachment structure with which a heat insulating material is easily and simply attached to a construction on the ground.[Means of overcoming the problem] An attachment structure for a heat insulating material 10 installed on a foundation F having a building fixed on an upper portion thereof comprises a wall plate 15 which maintains the heat insulating material in a state of being in proximity to and facing an outside surface Fs, rising from ground E, of the foundation, and an attaching device 20 which positions and retains the wall plate in such a way as to be capable of sliding in a direction parallel to the foundation, wherein: the wall plate is formed as a structure that is positioned on a rear surface side of the heat insulating material with respect to the foundation, and that maintains the facing state of the heat insulating material by sandwiching the same against the outside surface of the foundation; the attaching device includes an upper retaining portion 21 which retains an upper portion of the wall plate on an upper portion of the foundation in a non-detachable manner, and a lower retaining portion 23 which retains a lower portion of the wall plate on the outside surface of the foundation so as to be non-detachable in a separating direction; the lower retaining portion is formed as a receiving structure which receives the lower portion of the wall plate in a placed state; and the upper retaining portion is formed as a structure which faces a rear surface side, with respect to the heat insulating material, of the upper portion of the wall plate, and which restricts movement of the upper portion of the wall plate in the separating direction.
