To provide a flat plate-like gap closing tool that can be applied to various kinds of pipes with different diameters, can make a mortar surface, which is filled into a gap between a pipe and a floor slab and solidified, substantially flat, is easy to visually confirm a filling state of mortar, and is easy to store and manage.SOLUTION: A gap closing tool 1 for carrying fluid mortar that closes a gap between a pipe passing through a floor slab and the floor slab, is formed into a flat plate composed of a shape retaining layer 10 made of a flexible resin layer, and an adhesive layer 20. The flat plate is provided with a hole 31 for attaching the flat plate to the pipe, and a plurality of arc-shaped long holes 40 evenly arranged so as to form a concentric circle with the hole. The flat plate is narrowed in a plane direction so that it is attached to the floor slab in a substantially flat state, and an inside edge 34 of a belt-shaped part 42 is brought into close contact with the outer periphery of the pipe to eliminate mortar leakage, so that even a single gap closing tool can be applied to various types of pipes with different diameters. An attachment area is provided with strip-like dividing means (cuts) 60 extending in a radial direction.SELECTED DRAWING: Figure 1 【課題】直径が異なる複数種類の配管に適用可能であると共に、配管と床版との隙間に充填させて固化させたモルタル面を略平坦とすることが可能であり、モルタルの充填状態が目視で確認しやすいと共に、保管・管理しやすい、平板体をなす隙間閉塞具を提供する。【解決手段】床版を貫通する配管と床版との隙間を塞ぐ流動性モルタルを担持する隙間閉塞具１を、可撓性を有する樹脂層からなる形状維持層１０と、接着層２０とからなる平板体とさせた。平板体に、平板体を配管に装着させる孔３１と、孔と同心円をなすように均等に配された複数の円弧状長孔４０とを備えさせ、平板体を面方向に窄めて略平坦な状態で床版に貼着されるようにし、帯状部４２の内側縁３４を配管の外周に密着させモルタルの漏れをなくし、ひとつの隙間閉塞具であっても、直径が異なる複数の種類の配管に適用可能とさせた。装着領域に、径方向に伸びる筋状の分断手段（切れ目）６０を備える。【選択図】図１
