PROBLEM TO BE SOLVED: To solve a problem that: a conventional underfloor inspection hole (Figure 6) is accompanied by a step of attaching a rotary hand hold at a work site; and a boring processing is required for fitting an outer frame to an opening opened by cutting a floor material and attaching the rotary hand hold to utilize the floor material of the opening for a cover pane; this processing include many step and requires technical skill and a special tool, thus requiring time and technique for execution.SOLUTION: Although an inventive underfloor inspection hole frame is the same as a conventional one in terms of the manner that a cover panel 5 is utilized, a rotary hand hold 3 is attached to a frame material 1a in the case of the inventive one, and processing includes simply straight cutting, can be performed even without technique, and an electrically-driven saw or the like is sufficient as a tool. Thus, the time for execution can be remarkably reduced and an underfloor inspection hole material for labor saving execution is provided. Moreover, a hand hold of a cover part 5 is eliminated and an indoor excellent in design and aesthetic appearance can be achieved. |
