ところで、上記した何れの実施の形態でも止め具１に対してタッピングねじ５がセットで使用されているが、タッピングねじ５の代わりに釘を使用することも可能である。
さらに、上記した実施の形態では止め具１とタッピングねじ５または釘は天井点検口の断熱外枠１５や床下点検口または床下収納庫の断熱外枠３１の取り付けに使用しているが、建物の開口部としては天井点検口、床下点検口、床下収納庫に限定されるものではなく、壁面などに形成される開口部内の断熱構造にも使用できるものである。また、前記止め具１とタッピングねじ５または釘は断熱外枠以外の発泡スチロールからなる製品の取り付けにも使用できるものである。 Incidentally, in any of the above-described embodiments, the tapping screw 5 is used as a set with respect to the stopper 1, but a nail can be used instead of the tapping screw 5.
Furthermore, in the above-described embodiment, the stopper 1 and the tapping screw 5 or the nail are used to attach the heat insulation outer frame 15 of the ceiling inspection opening, the floor inspection opening, or the heat insulation outer frame 31 of the underfloor storage. The opening is not limited to a ceiling inspection port, an underfloor inspection port, and an underfloor storage, but can also be used for a heat insulating structure in an opening formed on a wall surface or the like. Further, the stopper 1 and the tapping screw 5 or the nail can be used for attaching a product made of foamed polystyrene other than the heat insulating outer frame.
