By the way, in the case of such a conventional method, when one jack 4 is used to raise and raise, depending on the mounting position of the jack 4,
As the building of the wall 2 progresses, the balance of the wall 2 may collapse and tilt, so as shown in the figure,
By installing a pair of jacks 4 at intervals in the surface direction of the wall and operating the pair of jacks 4 so that the amount of movement thereof is constant, the posture of the wall 2 is controlled and the erecting is performed. I am trying.

However, when the pair of jacks 4 are simultaneously operated to erect the wall 2 as described above, if the operation amounts of the two jacks 4 are different, the same as the case of erecting with one jack 4. In addition, it is assumed that the wall 2 is out of balance and the wall 2 comes off the slip stopper 5. In particular, since both jacks 4 are installed apart from each other and need to be operated by a plurality of workers, the above-mentioned troubles are likely to occur.

Since the operation of the jack 4 is performed on the side where the wall 2 falls down, there is a problem in safety of workers.

Further, for example, in a prefabricated house,
When the wall 2 is installed on the base, after the wall is built up, the wall 2 is pulled up above the base, aligned with the anchor bolts protruding from the base, and then lowered, and the anchor bolts are lowered. There is a construction method in which the wall is inserted into the lower end of the wall 2 and fixed.

However, when the conventional technique is applied to such a construction method, since the wall 2 is erected by rotating around the anti-slip 5, it is installed vertically to the base. It is difficult to insert the anchor bolt, and the operation must be performed by a separate lifting operation.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a wall erecting device capable of easily and safely erecting a heavy wall. To do.
