ず，必ずしも汎用的でない。The construction method in which the outer wall panels are lifted one by one by the crane vehicle and a plurality of workers receive them by hand is not efficient as the work itself for transporting the outer wall panels. In addition, the work of removing the outer wall panel from the hook of the crane and receiving it is complicated, and this is also inefficient. In addition, it requires a large layout and work space for mobile cranes to transport the outer wall panels to a high place, and it is often difficult to take such a large space at some construction sites. In addition, the method of forming a large panel and the method of holding the outer wall panel on the lifting jig so as to be able to slide laterally require that the structure of the outer wall panel itself be adapted to the construction method, and is not necessarily general-purpose. .

である。Next, as shown in FIG. 2, after the furring strip 41 is attached to the furring strip 7 at the lifting position of the lifting pallet, the wire 43 connected to the lifting side of the lifting pallet 10 is attached to the lifting machine 11. The lifting pallet 10 is hung by a lifting machine 11 as shown in FIG. 3, and is hung vertically as shown in FIG. During this time, the bottom plate side 16d side of the lifting pallet 10 is pulled by the rope 39 and is smoothly lifted so that the upper end side of the lifting pallet 10 does not contact the furring strip 7 side. The furring ridge protective material 41 prevents the upper end side of the lifting pallet 10 from hitting the furring rim 7 or plunging inward from between the furring rims 7. The furring strip 41 is removed when the outer wall panel 3 is attached to the furring strip 7 at that location. At this stage, the open surface 1 of the lifting pallet 10
Since 4 is facing away from the furring strip 7, the lifting pallet 10 is then rotated 180 ° so that the open surface 14 side faces the furring strip 7 side. Next, as shown in FIGS. 5 and 6, the anti-sway wire 12 is passed through the wire guides 33 at the four positions of the lifting pallet 10 from the side, and the winch 36 is operated while watching the spring type balance 37. Appropriate tension is applied to the shake prevention wire 12. The operation of the lifting machine 11 is performed wirelessly by an operator on the ground. Subsequently, the operator on the ground wirelessly operates the lifting machine 11 to lift the lifting pallet 10 and stop it at a predetermined height position.
It should be noted that wireless operation of the lifting machine 11 by an operator on the ground when the lifting pallet 10 is on the upper side, such as stopping at the predetermined height position and lateral movement of the lifting pallet 10 described below, is performed by the operator on the upper side. Follow the wireless instructions in. Then, the lifting machine 11 is run along the lifting machine rail 31 and laterally moved to a predetermined mounting position. During this lateral movement, the tension of the anti-sway wire 12 is relaxed and the electric traveling carriage 35 of the tension applying device 13 is caused to travel in synchronization with the movement of the lifting machine 11. The electric traveling carriage 35 is run by an operator on the ground by operating a wired push button. Immediately after the movement, tension is applied to the shake prevention wire 12. When the lifting pallet 10 comes to a predetermined position, an operator standing on a plurality of scaffolds 42 arranged vertically as shown in FIG. 6 removes the fall prevention member 15 and takes out the outer wall panel 3, and the joint bar 4 Take out and attach to the furring strip 7 with the metal fitting 5, bolts 6 and nuts 8. This outer wall panel 3
The attachment of the to the furring strip 7 is as shown in FIGS.

順に建て込む。When the attachment of one outer wall panel 3 to the furring strip 7 is completed, after one outer wall panel 3 is laterally moved,
Similarly to the above, the outer wall panel 3 and the joint bar 4 are taken out and attached to the furring strip 7. The outer wall panel 3 is built in the whole by repeating the above-mentioned attaching process and moving process. In this way, when the building of the outer wall panel 3 of the first stage is completed, the building of the outer wall panel 3 of the next stage is performed. Since the length of the outer wall panel 3 is usually different for each stage, a lifting pallet 10 corresponding to the length of the outer wall panel 3 of the stage is prepared. And
The lifting height position of the lifting pallet 10 is changed to the height position of the construction step, and the outer wall panel for the next one step is built by the same construction method as described above. In FIG. 14, the middle and lower outer wall panels 3 have been built, and the upper one is being built. However, normally, the upper, middle, and lower outer walls are built in this order.

In short, it may be a long and narrow box-like one that can accommodate a plurality of outer wall panels 3 directly or indirectly from the open surface side that is the upper side when placed on the ground. In the embodiment, the lifting pallet 1
Each outer wall panel 3 in 0 is housed on the shelf member 20, that is, the outer wall panel 3 is housed in the lifting pallet in an indirectly overlapping manner, but the outer wall panel is directly mounted depending on the sectional shape. It is conceivable to store them in layers.

If there is a hoisting equipment (temporary gondola traveling rail and hoisting machine for hoisting the gondola), using that hoisting equipment does not require a separate hoisting equipment and is efficient. is there. However, when there is no such hoisting equipment, a temporary hoisting equipment for exclusive use for outer wall panel construction (rail 31 for hoisting machine)

In addition, it is easy to take out the outer wall panel from the vertically suspended, elongated box-shaped lifting pallet with an open surface, which also improves workability. In addition, because a crane truck for lifting the lifting pallet is not required, the space for arranging the crane truck becomes unnecessary,
In particular, the improvement of workability at construction sites where space is limited is extremely large. In addition, the construction method of the present invention is less restricted by the structure of the outer wall panel itself, and is therefore highly versatile. In addition, if there is a lifting equipment that is a permanent equipment that remains after the building is completed, or if there is a temporary lifting equipment used for the entire construction work, that lifting equipment can be used, which is efficient. The construction cost can be further reduced.
