JACK DEVICE FOR UNDERGROUND STRUCTURE LID RECEIVING FRAME
PROBLEM TO BE SOLVED: To provide a jack device with a simple structure, which can easily remove an inner cylindrical body of a lid receiving frame formed of an outer cylindrical body and the inner cylindrical body and can be easily handled.SOLUTION: A jack device for underground structure lid receiving frame comprises: a construction base slab 6, which is constructed at an inner bottom base part 2a of an outer cylindrical body 2 of a lid receiving frame A formed of the outer cylindrical body 2 and an inner cylindrical body 3; and a strip-like lifting slab 7, which is screwed with a screw rod 8 at a center part and has a length to allow a lower surface of a convex edge 3a formed inside the inner cylindrical body 3 to be engaged with both ends of the lifting slab. An ornamental hairpin-shaped handle 9 is installed on a head 8a of the screw rod 8. The lifting slab 7 can be vertically moved up or down by rotating the screw rod 8 using the handle 9.SELECTED DRAWING: Figure 1
【課題】 外筒体と内筒体からなる蓋受枠の内筒体を簡単に外すことが出来る構造簡単で使い勝手のよいジャッキ装置を提供する。【解決手段】外筒体２と内筒体３からなる蓋受枠Ａの前記外筒体２の内底ベース部２ａに架設する架設基版６と、中央にネジ杆８を螺合し、且つ長さが前記内筒体３の内部に設けた突縁３ａの下面と両端が係合する長さの短冊状の扛上版７とから成り、ネジ杆８の頭部８ａに簪状のハンドル９を設ける。扛上版７はハンドル９によりネジ杆８を回動させることにより上下に昇降させることが出来る。【選択図】図１
