盛り替えることにより上昇の一工程が終了する。The lower lock pin device 7 is driven to lock the lock pin 7a on the reaction force receiving portion 8 of the column 1 (see FIG. 4).
A) When the jack 2 located on the inner side of the column 1 is extended, the lower pedestal 4 loses its balance due to an eccentric load, but at this time, the engagement pin 24 causes the rib 22 of the column 1 to lose its balance.
It is possible to maintain the balance by engaging with the engaging hole 23 of. Engagement pin 2
Even if the ribs 4 and the ribs 22 are not provided, the lower pedestal 4 can be kept in balance by the frictional resistance (restraining force) of the guide roller 5 contacting the side surface of the column 1. When the object 20 to be lifted, such as a building beam or floor, is placed on the upper pedestal 3 which is lifted by the extension operation of the jack 2, it is pushed up (FIG. 4B). On the contrary, when the upper lock pin device 6 is driven to lock the lock pin 6a on the reaction force receiving portion 8 of the support 1 and the jack 2 is contracted, the upper base 3 loses the balance due to the unbalanced load. At this time, the engagement pin 24 is engaged with the engagement hole 23 of the rib 22 of the support column 1 to maintain the balance. Of course, the balance is similarly maintained only by the action of the guide roller 5.
As a result of the contraction operation of the jack 2, the lower pedestal 4 is raised, and as a result, the object to be lifted coupled to the lower pedestal 4 is pulled up. After that, the lower lock pin device 7 is hooked on the column 1 to take a reaction force, the upper lock pin device 6 is released, and the load is replenished, whereby one ascending step is completed.

Installation work can be performed easily by incorporating and connecting the base jack 2. Of course, the disassembly work can be easily performed by executing the reverse procedure. This composite jack device is, for example, as shown in FIG. 4A after the above-mentioned preparation for installation is completed.
As described above, the lifted body 20 such as the floor frame structure or roof frame of the building is placed on the upper frame 3, and first, the lower lock device 7 is driven, and the lock pin 7a is mounted on the reaction force receiving portion 8 of the column 1. Then, the engaging pin 24 is engaged with the engaging hole 23 to prepare for rising. Next, the jack 2 is extended to push up the lifted body 20 (FIG. 4B). At this time, the lower pedestal 4 maintains a well-balanced and stable state, and the upper pedestal 3
Also, due to the guiding action of the guide roller 5, a smooth and stable upward movement is performed without causing lateral shake or the like. As shown in FIG. 5A, when the jack 2 has fully extended to its effective stroke, the upper lock pin device 6 is driven and the lock pin 6 a is hooked on the reaction force receiving portion 8 of the column 1 to reduce the load. Refilling is done. That is, when the jack 2 is slightly contracted, the entire load is supported by the upper lock pin device 6 and the lower lock pin device 7 is in an unloaded state. Therefore, at this stage, the clamp jack 9 as the drive unit is retracted. The lock pin 7a is removed from the reaction force receiving portion 8, and the engagement pin 24 is pulled out from the engagement hole 23. After that, when the jack 2 is contracted, the lower mount 4 is raised (FIG. 5B). Therefore, if the object to be lifted is connected to the lower mount 4, it will be lifted. When the jack 2 contracts all of its effective stroke, the lower lock pin device 7 of the lower pedestal 4 is operated to apply a reaction force to the reaction force receiving portion 8 of the column 1, and further engage the engagement pin 24. When it is engaged with the hole 23 (FIG. 5C), the state similar to that of FIG. 4A is restored, and the ascending of one step (expansion and contraction of the jack 2) is completed. Further, during the operation of the above-described composite jack device, as shown in FIGS. 1 and 3A, since the outer steel materials 16 on the upper and lower mounts 3 and 4 are close to the outer wall 21 of the building, the outer wall 21 is attached. There is no hindrance to the construction of other exterior work.

とって駆動階をプッシュアップすることになる。When the above-described composite jack device is used in a push-up construction method or the like, the jacks 2 are installed on the columns 1 in the respective horizontal XY directions of the plan view of the building shown in FIG. To be done. For this reason, each jack device jacks up one side of the column 1 in an unbalanced load state, but since the jack devices are symmetrically arranged on the opposite side of the entire building, the balance is achieved in the XY directions. It will push up the driving floor.

切支障がない。The ascending process (and hence the descending process) of the composite jack device described above is controlled by a hydraulic circuit (not shown). However, since there are two jacks 2, the hydraulic circuit is greatly simplified. Is possible. FIG. 7: is a top view which showed the case where the compound jack apparatus was installed in the pillar 1 of the part where the outer wall 21 of a building is linear. Inner steel 15
The jack 2 and the lock pin devices 6 and 7 are located on the inner side of the column 1 when viewed from the outer wall 21, and the outer steel material 16 has a planar shape that can be raised and lowered while being housed inside the linear outer wall 21. Therefore, as in the case of the corner portion shown in FIG. 1, there is no hindrance to the attachment of the outer wall 21 or the construction of the exterior work.

The output shaft 2b of the jack 2 and the upper lock pin device 6 are connected to the drive floor 20, the outer steel material 16 is also made as small as possible, and the engaging pin 24 is omitted. Therefore, the imbalance of the lower pedestal 4 during the push-up operation of the jack 2 is stabilized by the roller guide 5. Since there is no upper pedestal 3, it is possible to reduce the weight of the jack device itself and reduce the equipment cost and the assembly / disassembly cost. In addition, as in the above embodiment, the engaging pin 24 is attached to the support 1
It is also possible to employ a jack device configured to engage with the engagement hole 23 provided in the.
