A plurality of adjustment packings 27 are attached to the wall lower surface 25 at intervals, and the space between the adjustment packings 27 is defined as the escape space 26. The adjustment packing 27 is, for example, a structural plywood. By attaching the adjustment packing 27 to the bottom surface Wb of the wall body W, the escape space 26 may be formed on the bottom surface Wb side.

  Further, the locking member 28 is attached on the floor, and the locking member 28 and the through hole 22 of the wall body W are connected in advance in a state where the wire 29 for preventing the wall body W from falling is loosened. The wire 29 here includes a chain in addition to a steel wire or the like.

  When the above work is finished, the wall pump arm P is operated to rotate the wall body support arm 7 so that the wall body W is built up. Then, as shown in FIG. 6A, tension is applied to the wire 29 at a stage just before the wall body W stands up completely. The stage immediately before standing completely refers to a state where the erection angle is approximately 85 degrees. In this state, the through holes 23 of the wall body W are positioned substantially concentrically with respect to the anchor holes 24, so that the anti-slip anchors 30 of the wall body W are inserted into these holes.

  Then, the operator attaches the wire 29 in the middle of the wire 29 so that tension is always applied to the wire 29 from the state of FIG. 6A until the wall body W shown in FIG. The hoist 31 is operated with a lever to adjust the wire length. As a work form of the operator, the lever operation of the hoist 31 is performed with one hand, and the pumping operation of the lever of the hydraulic pump P is performed with the other hand.

  As shown in FIG. 6B, when the wall body W stands up completely, the bottom surface support portion 6 is positioned in the escape space 26, and the bottom surface Wb is the wall lower surface 25 (in this case, it means the upper surface of the adjustment packing 27). The erection operation of the wall body W is completed by contacting the surface. After this, for example, after building another wall body orthogonal to the wall body W, etc., the wall body raising device 1 is moved in the right direction in FIG. 6B to remove the wall body raising device 1. To do.

  As described above, the bottom surface support portion is provided on at least one of the wall bottom surface 25 and the bottom surface Wb so that the wall bottom surface 25 and the bottom surface Wb of the wall body W are in contact with each other when the wall body W is erected on the wall bottom surface 25. If the six relief spaces 26 are formed, a simple erection method using the wall erection device 1 can be constructed. At this time, if the escape space 26 is a space between the adjustment packings 27 that are installed on the wall lower surface 25 at intervals, a simpler erection method can be constructed.

  Further, in a state where the wall body W is horizontally placed on the wall body support means 2, the wire 29 for preventing the wall body W from falling is loosened between the upper edge of the wall body W and the floor. This is a construction method in which the wall body W is erected while adjusting the wire length manually and always applying tension to the wire 29 until the wall body W is completely erected from the stage before the wall body W is completely erected. Thus, the posture of the substantially standing wall body W can be stabilized without requiring a lot of human hands, and a situation in which the wall body W excessively falls to the back side when standing can be prevented.

  Further, before the wall body W completely stands up, the wall body W slides into the anchor hole 24 drilled in the floor through the through hole 23 drilled in the lower part of the frame Wc of the wall body W. If the prevention anchor 30 is inserted, it is possible to stabilize the position of the wall body W in the substantially upright state without requiring a lot of human hands. You can prevent the situation of sliding.
