The height of the legs of the frame body 4 is larger than the height of the deflated airbag 3 (3A, 3B), and when the frame body 4 is placed on the deflated airbag 3 (3A, 3B), A space 13 is formed between the back 3 (3A, 3B) and the frame 4.
XX sectional view (b) shows the frame 4 by sending compressed air from the air supply pipe 8 (8A, 8B) into the airbag 3 (3A, 3B) and inflating the airbag 3 (3A, 3B). Shows the situation when pushing up and supporting the object.
The substrate 5 and the frame body 4 are made of various materials such as steel and rubber, and have a shallow mortar-shaped recess 14, and the airbag 3 (3A, 3B) is sufficiently expanded in the recess 14. The size should be in contact with the bulges of the upper and lower surfaces of the airbag. The recess 14 is formed without penetrating the frame 4 or the substrate 5 and has a shape that does not come into contact with the object or the bottom plate 2 or the foundation 12 when the airbag 3 (3A, 3B) is inflated. However, if there is no problem in the function of the air jack device, the recess 14 may be formed so as to penetrate the frame 4 or the substrate 5.
Since the air jack device fixes the position of the airbag 3 (3A, 3B) by the frame body 4 and the substrate 5, the position of the airbag 3 (3A, 3B) does not shift during expansion, and is more stable. The object can be held, pushed up, and lowered.
Further, even when the airbag 3 (3A, 3B) is sufficiently inflated and the upper and lower surfaces are not parallel, the expanded portions of the upper and lower surfaces of the airbag 3 (3A, 3B) Since the upper and lower surfaces of the frame 4 on the airbag 3 (3A, 3B) are maintained in parallel with each other in contact with the recess 14, the object can be held, pushed up, and lowered in a horizontal state.
Furthermore, the airbag 3 (3A, 3B), the frame 4 and the substrate 5 can be easily stacked, and the object can be pushed up and the support height can be easily adjusted.

対象物が大型の場合は、複数の上記エアバック３（３Ａ、３Ｂ）やエアジャッキ装置を対象物と基礎１２や底板２等との間に設置し、個々の位置のエアバック３（３Ａ、３Ｂ）に圧縮空気を供給または排出して膨張または収縮させて、基礎の勾配等を考慮してエアバック３（３Ａ、３Ｂ）毎に対象物を押し上げまたは下降して、対象物全体を適切な高さに保持する。   When the object is large, a plurality of the airbags 3 (3A, 3B) and air jack devices are installed between the object and the foundation 12, the bottom plate 2, etc., and the airbags 3 (3A, 3A, Compressed air is supplied to or discharged from 3B) and expanded or contracted, and the object is pushed up or down for each airbag 3 (3A, 3B) in consideration of the gradient of the foundation, etc. Hold at height.

図４は、浮屋根式タンクの浮屋根をエアバック３（３Ａ、３Ｂ）を用いたエアジャッキ装置で押し上げる事例を説明する図で、エアジャッキ装置のエアバック３（３Ａ、３Ｂ）を膨張させて浮屋根を押し上げ、支持している状況を示す。また、図４は、空気供給管８Ａが１本接続されたエアバック３Ａを用いたエアジャッキ装置の事例を示す。
１は浮屋根、２は底板、３（３Ａ、３Ｂ）はエアバック、４は枠体、５はエアバック３および枠体４の基板、６は盤木、７は支柱、８（８Ａ、８Ｂ）は空気供給管である。なお図４は、支柱７を支持材７ａ、柱部７ｂ、当接材７ｃで構成しているが、支柱７は種々の形状、機能を有すものを使用することが可能である。
浮屋根１の押し上げは、底板２上に載置した基板５の上にエアバック３（３Ａ、３Ｂ）を載置し、エアバック３（３Ａ、３Ｂ）を囲うように枠体４を設け、次いで高さ調節用の盤木６を敷き、その盤木６の上に支柱７を底板２上面に対して垂直に立設する。続いて、空気供給管８（８Ａ、８Ｂ）からエアバック３（３Ａ、３Ｂ）内へ圧縮空気を送って膨らませ、枠体４、盤木６、支柱７を介して浮屋根１を押し上げる。
なお、底板２上に基板５、エアバック３（３Ａ、３Ｂ）、枠体４、支柱７を設置した際に浮屋根１を押し上げ、支持する高さが十分に確保できれば、盤木６は設置しなくても良い。
浮屋根補修工事の際は、デッキサポート（図示せず）近傍の必要箇所に上記エアジャッキ装置を設置し、浮屋根１を押し上げ、支持し、デッキサポートや底板２の取替え、基礎の改修、浮屋根１の補修等を実施する。また、浮屋根１の荷重を一時的に支持する仮支持材（図示せず）を必要に応じて設置する。
上記浮屋根１のエアジャッキ装置は、エアバック３（３Ａ、３Ｂ）に圧縮空気を供給して膨張させると、エアバック３（３Ａ、３Ｂ）上の枠体４が水平状態で押し上がるため、盤木６、支柱７を介して浮屋根１を水平状態で安定して保持、押し上げ、下降させることが可能である。
また、上記浮屋根１のエアジャッキ装置は、エアバック３（３Ａ、３Ｂ）の位置が前記枠体４と基板５により固定されるため、エアバック３（３Ａ、３Ｂ）の位置が膨張時にずれることがなく、より安定して浮屋根１を保持、押し上げ、下降させることが可能である。
さらに、上記浮屋根１のエアジャッキ装置は、エアバック３や枠体４、支柱７等の持ち運びが容易な複数の部材を浮屋根１下面の所定の場所まで個々に搬入し、容易に組み立てることが可能で、取付け、取外しの作業も容易であり、従来の油圧式等のジャッキ装置を使用する場合と比較して浮屋根１を押し上げる作業に手間と人手を要することがない。
さらにまた、上記浮屋根１のエアジャッキ装置は、エアバック３、枠体４、基板５を複数段積み重ねることにより、容易に浮屋根１の押し上げ、支持高さを調整することが可能である。 FIG. 4 is a diagram for explaining an example of pushing up a floating roof of a floating roof type tank with an air jack device using an air bag 3 (3A, 3B). The air bag 3 (3A, 3B) of the air jack device is expanded. Shows the situation where the floating roof is pushed up and supported. FIG. 4 shows an example of an air jack device using an air bag 3A to which one air supply pipe 8A is connected.
DESCRIPTION OF SYMBOLS 1 is a floating roof, 2 is a baseplate, 3 (3A, 3B) is an airbag, 4 is a frame, 5 is a board | substrate of the airbag 3 and the frame 4, 6 is a board, 7 is a support | pillar, 8 (8A, 8B) ) Is an air supply pipe. In FIG. 4, the support column 7 is composed of the support material 7 a, the column part 7 b, and the contact material 7 c, but the support column 7 can have various shapes and functions.
The floating roof 1 is pushed up by placing the airbag 3 (3A, 3B) on the substrate 5 placed on the bottom plate 2, and providing the frame 4 so as to surround the airbag 3 (3A, 3B). Next, a board 6 for height adjustment is laid, and a column 7 is erected on the board 6 perpendicularly to the upper surface of the bottom plate 2. Subsequently, compressed air is sent from the air supply pipe 8 (8A, 8B) into the air bag 3 (3A, 3B) to be inflated, and the floating roof 1 is pushed up through the frame body 4, the wood block 6, and the column 7.
In addition, when the board | substrate 5, the airbag 3 (3A, 3B), the frame 4, and the support | pillar 7 were installed on the baseplate 2, the floating roof 1 will be pushed up, and if the height to support can be ensured enough, the board 6 will be installed. You don't have to.
During floating roof repair work, install the above air jack device near the deck support (not shown), push up and support the floating roof 1, replace the deck support and bottom plate 2, repair the foundation, lift The roof 1 will be repaired. Moreover, the temporary support material (not shown) which supports the load of the floating roof 1 temporarily is installed as needed.
When the air jack device of the floating roof 1 is supplied with compressed air to the airbag 3 (3A, 3B) and inflated, the frame 4 on the airbag 3 (3A, 3B) is pushed up in a horizontal state. It is possible to stably hold, push up, and lower the floating roof 1 in a horizontal state through the block 6 and the column 7.
Moreover, since the position of the air bag 3 (3A, 3B) is fixed by the frame body 4 and the substrate 5 in the air jack device of the floating roof 1, the position of the air bag 3 (3A, 3B) shifts during expansion. The floating roof 1 can be held, pushed up and lowered more stably.
Furthermore, the air jack device of the floating roof 1 is configured to easily carry a plurality of members such as the airbag 3, the frame body 4, and the support 7 to a predetermined place on the lower surface of the floating roof 1 and easily assemble them. The mounting and removal work is easy, and the work of pushing up the floating roof 1 does not require labor and manpower as compared with the case where a conventional hydraulic jack device is used.
Furthermore, the air jack apparatus of the floating roof 1 can easily push up the floating roof 1 and adjust the support height by stacking the airbag 3, the frame body 4 and the substrate 5 in a plurality of stages.

図３および図４のエアジャッキ装置は、対象物押し上げ時の安定性を向上させるために、図１のエアバック３Ａまたは図２のエアバック３Ｂを使用することが好ましいが、従来のエアバックを使用することも可能である。
従来のエアバックを重量物の保持、押し上げ、下降に使用すると、上部に載置した対象物の荷重により、空気供給管近傍部から膨らみ、対象物の押し上げ、支持が不安定になる問題があった。図３および図４のエアジャッキ装置は、四隅に脚を有す枠体４で萎んだエアバックを囲み、該エアバックと枠体４との間に空間１３を形成するため、エアバックが空気供給直後から対象物の荷重の影響を受けずに膨張し、該エアバックが十分に膨張した段階で枠体４を介して水平状態で対象物を押し上げ、支持することが可能である。
したがって、従来のエアバックを本発明のエアジャッキ装置に使用した場合においても、安定して対象物を押し上げ、支持することが可能である。
The air jack device of FIGS. 3 and 4 preferably uses the airbag 3A of FIG. 1 or the airbag 3B of FIG. 2 in order to improve the stability when pushing up the object. It is also possible to use it.
If a conventional airbag is used to hold, push up, and lower heavy objects, it will swell from the vicinity of the air supply pipe due to the load of the object placed on the upper part, causing the problem of the object being pushed up and unstable. It was. The air jack device of FIGS. 3 and 4 surrounds the air bag that is deflated by a frame body 4 having legs at four corners, and forms a space 13 between the air bag and the frame body 4. It is possible to inflate without being affected by the load of the object immediately after the supply, and to push up and support the object in a horizontal state via the frame body 4 when the airbag is sufficiently inflated.
Therefore, even when a conventional airbag is used in the air jack device of the present invention, it is possible to push up and support the object stably.

この発明に係るエアバッグと該エアバッグを用いたエアジャッキ装置は、浮屋根式タンクの浮屋根を含む種々の構築物の保持、押し上げ、下降に広く適用することが可能である。

The airbag according to the present invention and the air jack apparatus using the airbag can be widely applied to holding, pushing up, and lowering various structures including the floating roof of a floating roof type tank.
