As shown in FIG. 7, the auxiliary rope 16 attached to the lifting balance 7 is hung on the side of the wall material 10 facing the building housing 15, and the auxiliary rope 16 is connected to the branch sling 3. The wall material 10 can be easily aligned by pulling. Further, the wall material 10 can be prevented from shaking by using the auxiliary rope 16 when the wall material 10 is moved or lowered. In addition, as another role of the auxiliary rope 16, it is useful for preventing the secondary wall material 10 from falling off. If two or more auxiliary ropes 16 are fixed to the main sling 2 or the branch sling 3, even if one of the auxiliary ropes 16 does not function, the wall material suspended above by the other auxiliary ropes 16 10 can be prevented from falling.

  When the installation of the lowermost wall member 10 is completed, the suspension member 1 is lowered by the vertical distance d between the wall members, and the second wall member 10 from below is lowered from the bottom as shown in FIG. Supply to the 2nd erection position. When the second-stage wall member 10 from the bottom is attached to the building housing 15, the upper end portion of the lower wall member 10 is fitted into the recess 14 at the lower end portion of the upper wall member 10, as shown in FIG. Thus, the two wall members 10 adjacent to each other in the vertical direction are fixed to each other. When both wall members 10 are fixed in this way, the wall members are firmly bonded to each other, and the wall members can be fixed without using other members, so that the wall member 10 can be easily attached. In the same manner, all the wall materials 10 are attached to the building frame 15.

  According to the wall construction method using the suspension material 1, when the installation of one wall material 10 is completed, the next wall material 10 can be supplied immediately, and the wall material 10 can be efficiently attached. In addition, when the wall material 10 is transported from the temporary storage space to the building housing 15, the plurality of wall materials 10 can be transported at a time by suspending the plurality of wall materials in multiple stages by the suspension material 1, thereby shortening the time. Can be achieved.
