  The wall panel 10 to be used by the upper panel drop prevention jig 1 has a horizontally long shape as shown in FIG. 3 and 3 to 5 sheets correspond to the first floor of the building. For example, as shown in FIG. 2, the cross section of the wall panel 10 has a configuration in which a heat insulating material 13 is sandwiched between an outer skin material 11 and an inner skin material 12 both made of a metal plate. The outer skin material 11 and the inner skin material 12 are a plated steel plate, an aluminum plate, or the like. The heat insulating material 13 is rock wool, foamed polystyrene, urethane, or the like.

  The upper end portion of the wall panel 10 is formed by bending the outer skin material 11 and the inner skin material 12 so that the surfaces on the outdoor side and the indoor side are retracted by distances a and b, respectively, on the inner side in the thickness direction of the wall panel 10 than the others. It is as. The vertical dimension c of the outdoor upper end retreating portion 14 is longer than the vertical dimension d of the indoor upper end retreating portion 15. The top ends of the outer skin material 11 and the inner skin material 12 are lip portions 11a and 12a bent inward.

  Moreover, the lower end part of the wall panel 10 is made into the shape which became the lower end folding | returning parts 16 and 17 which turned up the lower end part of the outer skin | cover material 11 and the endothelial material 12, and the thickness direction center part is a dent which opens to a lower end side.

The recess 18 is provided with a packing 20 at the same position in the thickness direction as the lip parts 11b and 12b, and a plug 21 made of ceramic fiber or the like at the same position in the thickness direction as between the lip parts 11b and 12b.

  In the state of being built in the building frame, as shown in FIG. 2 (B), the upper end retreat portions 14 and 15 of the lower wall panel 10 temporarily fixed to the building frame 23 by screws 22 such as tapping screws with a drill, The lower end folded portions 16 and 17 of the upper wall panel 10 are fitted. Thereby, the upper and lower wall panels 10 are fixed so as not to move in the thickness direction. The packing 20 and the plug material 21 are crushed by the weight of the upper wall panel 10. Temporary fixing with the screw 22 is performed on the upper end portion of the wall panel 10, and when another wall panel 10 is built on the upper side, the screw 22 is hidden from the upper wall panel 10 and cannot be seen from the outside.

The wall construction method performed using the upper panel drop prevention jig 1 will be described.
As shown in FIG. 3, a predetermined number (for example, four) of wall panels 10 for the first floor are suspended in multiple stages by a crane and moved from a material storage area at a construction site to a place where a building frame is attached. A suspension member set 25 is used to suspend the wall panel 10. The suspension material set 25 includes a horizontal bar-shaped jig (also referred to as “lifting balance”) 26 provided with a plurality of hooks 26 b at appropriate intervals on a steel frame material 26 a such as an H-shaped steel, and the horizontal bar-shaped jig 26. And a plurality of (for example, two) suspension members 27 depending on the suspension. The suspension member 27 is made of, for example, a nylon sling. The upper ends of the suspension members 27 are hooked on the hooks 26b at appropriate positions of the horizontal rod-shaped jig 26 so that the left and right suspension members 25 are balanced. Further, a sling wire 29 is attached to the horizontal bar-shaped jig 26, and the sling wire 29 is hung on a wire hook (not shown) of the crane. Then, a predetermined number of walls are connected to the predetermined height position of each suspension member 27 by connecting the connecting tool 30 attached to each upper portion of the predetermined number of wall panels 10 and lifting the suspension member set 25 with a crane. The panels 10 are suspended in multiple stages with a vertical interval e therebetween. As described above, when the suspension member set 25 having the plurality of suspension members 27 is used, each wall panel 10 can be suspended while being kept in an appropriate posture.

If the wall panel 10 suspended in multiple stages as described above is moved to the vicinity of the building housing 23 as shown in FIG. 4A, the lowermost wall panel 10 is positioned at the lowermost mounting position of the building housing 23. In addition, the building 22 is temporarily fixed with screws 22 (FIG. 2B). The alignment of the wall panel 10 is performed, for example, by an operator in the building housing 23 pulling the suspension material 27.
As shown in FIG. 5, if the auxiliary rope 31 attached to the horizontal bar-like member 26 is hung on the side of the wall panel 10 facing the building housing, and the auxiliary rope 31 is connected to the suspension member 27, the auxiliary rope 31 is pulled. Thus, the wall panel 10 can be easily aligned. Further, the swing of the wall panel 10 can be prevented by using the auxiliary rope 31 when the wall panel 10 is moved or lowered.

  Next, as shown in FIG. 4B, the upper panel is prevented from falling between the lower panel 10A, which is the wall panel 10 in the lowermost mounting operation, and the upper panel 10B, which is the upper wall panel 10. The jig 1 is arranged, and the lower panel 10A is attached to the building housing 15 in a state where the upper panel 10B is supported by the upper panel fall prevention jig 1.

  As shown in FIG. 6, the upper panel drop prevention jig 1 is arranged in such a manner that the vertical bar-like portion 2 stands vertically and the lower panel covering portion 3 is covered on the upper end portion of the lower panel 10 </ b> A, and the lower panel covering portion 3 is screwed. The lower panel covering portion 3 is prevented from being detached from the lower panel 10A by lightly applying the tip of the screw 30 screwed into the hole 5 to the side surface on the indoor side of the lower panel 10A. In this state, the upper panel 10B is lowered and the lower end of the upper panel 10 is received by the upper panel receiving portion 4. Since the cushioning material 6 is provided at the position where the lower edge of the lower panel 10A contacts the lower panel covering portion 3, and the cushioning material 8 is provided at the position where the upper edge of the upper panel 10B contacts the upper panel receiving portion 4. Each fore edge of the lower panel 10A and the upper panel 10B can be protected. Further, the cushioning material 7 of the lower panel covering portion 3 protects the side surface of the lower panel 10A by preventing the lower panel 10B from directly contacting the lower panel covering portion 3.

  As described above, when the upper panel drop prevention jig 1 is arranged, the vertical bar-like portion 2 receives the load of the upper panel 10B, thereby preventing the upper panel 10B from dropping unexpectedly. Since the lower panel covering portion 3 covers the upper end of the lower panel 10A, the upper panel drop prevention jig 1 is restricted from shifting in the wall thickness direction with respect to the lower panel 10A. Further, since the upper panel receiving portion 4 receives the lower end of the upper panel 10B, the upper panel 10B is restricted from shifting in the wall thickness direction with respect to the upper panel drop prevention jig 1. From these things, the mounting operation of the lower panel 10A can be performed safely.

  When the installation of the lowermost wall panel 10 is completed, the upper panel drop prevention jig 1 is removed, and the suspension member set 25 is lowered by the vertical interval e between the wall panels. As a result, as shown in FIG. 4C, the second-tier wall panel 10 from the bottom is supplied to the second-tier mounting location from the bottom. When the second-stage wall panel 10 from the bottom is attached to the building housing 23, the upper end of the lower wall panel 10 is fitted to the lower end of the upper wall panel 10 as shown in FIG. Thus, the two wall panels 10 adjacent to each other in the vertical direction are joined to each other. When the upper and lower wall panels 10 are joined in this way, the wall panels are firmly joined together, and the wall panels can be joined together without using other members, so that the wall panel 10 can be easily attached. In the same manner, all the wall panels 10 are attached to the building frame 23.

  According to the above-described wall construction method, when the installation of one wall panel 10 is completed, the next wall panel 10 can be supplied immediately, so that the wall panel 10 can be efficiently attached. Since the mounting operation is performed while supporting the upper panel 10B with the upper panel fall prevention jig 1, the upper panel 10B is not accidentally dropped and is safe. In addition, the upper panel fall prevention jig is simply placed and removed so that the lower panel cover is placed on the upper end of the lower panel and the upper panel receiving part receives the lower end of the upper panel, Good workability. Furthermore, even when carrying the wall panel 10 from the temporary storage area or the like to the building housing 23, the plurality of wall panels 10 can be carried at a time by hanging the plurality of wall panels 10 in multiple stages by the suspension material set 25. Time can be reduced.

  Although the upper panel fall prevention jig 1 of the above embodiment is entirely made of steel, the upper panel fall prevention jig 1 may be made of a resin material such as foamed urethane or hard urethane. In that case, the vertical bar-shaped portion 2, the lower panel covering portion 3, and the upper panel receiving portion 4 can be integrally formed, and processing is easy. In this example, the lower panel covering portion 3 has a groove shape into which the upper end of the lower panel 10A is fitted, and the upper panel receiving portion 4 has a groove shape into which the lower end of the upper panel 10B is fitted. Since the resin-made upper panel drop prevention jig 1 is entirely made of a soft material, it can also be used to maintain a distance between members other than the wall panel.
