AI Technical Summary

Technical Problem

Existing methods for repairing defective parts in shielding containers and piping, such as using rubber sheets and magnetic sheets, face issues with abrasion resistance, impact resistance, and material compatibility, necessitating worker entry for installation, which compromises safety and workability.

Method used

A fixing jig with a rotating member that can be inserted into the defective area and rotated to protrude from the fixing jig body, allowing secure attachment of a closing member without requiring worker entry, utilizing a rectangular fixing jig body and a rotating member that changes its protrusion state to lock onto the wall surface.

Benefits of technology

Enables easy and safe repair of defects in shielding containers and piping by securing a closing member without worker entry, addressing material compatibility and durability concerns, and facilitating easy removal and repositioning of the repair jig.

Abstract

To provide a fixing jig capable of fixing a closing member for repairing a defective part inside a wall surface, regardless of a material of the wall surface having the defective part, without an operator entering inside the wall surface.SOLUTION: A fixing jig for fixing a closing member to a defective part, has a rectangular fixing jig body, and a rectangular rotary member rotatably provided in the fixing jig body. The rotary member rotates about a rotational axis along a direction intersecting a longitudinal direction of the fixing jig body. As the rotary member rotates, it changes from a state in which both end parts of the rotary member do not protrude from both longitudinal side surfaces of the fixing jig body to a state in which both end parts protrude from both side surfaces.SELECTED DRAWING: Figure 1
