A temporary beam (not shown) is erected between the guide columns 41A and 41B and the skeleton 1. Therefore, the roller conveyors 23A and 23B are arranged between the vicinity of the root portion of the guide columns 41A and 41B and the rail 11.
There is a space between the side surfaces of the guide columns 41A and 41B and the skeleton 1, and a work scaffold (not shown) is built in the space.

A plurality of suspension balances (hanging jigs) 51A made of H-shaped steel are supported on the guide columns 41A so as to be movable in the vertical direction along the guide columns 41A. Specifically, as shown in FIG. 4, a slider 52A is provided at the end of the suspension balance 51A, the guide column 41A is inserted vertically into the slider 52A, and the radial load of the slider 52A around the guide column 41A and the radial load and A circumferential load is received by the guide column 41A. As a result, the slider 52A is provided so as to be slidable up and down along the guide column 41A. A roller that rolls as the slider 52A moves up and down may be provided on the inner surface of the slider 52A.

The slider 52A is configured to be removable from the guide support column 41A. In a state where the suspension balance 51A is attached to the guide column 41A by the slider 52A, the suspension balance 51A extends substantially horizontally from the guide column 41A in a direction away from the skeleton 1. These suspension balances 51A are arranged one above the other in a state of being substantially parallel to each other.

Similar to the guide column 41A, the suspension balance 51A, and the slider 52A, as shown in FIG. 2, the suspension balance 51B is vertically and vertically supported by the guide column 41B by the slider 52B.

A long beam 90 is arranged between the two flexible wire rods 54A. The long beam 90 is supported by a suspension balance 51A below it.
Similarly, the vertically adjacent suspension balances 51B are connected by two flexible wire rods 54B. A long beam 90 is supported between the two flexible wire rods 54B by a suspension balance 51B under the long beam 90. Therefore, the long beam 90 is supported in a state of being hung between the suspension balance 51A and the suspension balance 51B.

The uppermost suspension balance 51A is suspended from the hook 34A of the lifting device 32A by the sling 58A, and the plurality of suspension balances 51A are lifted and lowered by the lifting device 32A. Similarly, a plurality of suspension balances 51B are raised and lowered by the lifting device 32B (see FIG. 2).

2. 2. Stacking of long beams A method of stacking a plurality of long beams 90 along guide columns 41A and 41B will be described.

(1) Preparation, transportation and lifting of the first long beam First, as shown in FIG. 6, the first carriage 12A and the second carriage 12B are moved to the unloading place 3.
Next, the pedestal 95A made of H-shaped steel (see FIG. 5) is placed on the roller conveyor 13A of the first carriage 12A, and the pedestal 95A is temporarily fixed to the roller conveyor 13A or the first carriage 12A.
Next, the lifting machine 10 is used to unload the first H-shaped steel 90A from the loading platform of the freight vehicle onto the pedestal 95A of the first carriage 12A. At this time, the flange of the H-shaped steel 90A is turned up and down and the web is erected so that the longitudinal direction of the H-shaped steel 90A is substantially parallel to the rail 11.
Then, the H-shaped steel 90A is temporarily fixed to the pedestal 95A.

Next, by running the first carriage 12A, the H-shaped steel 90A on the first carriage 12A is conveyed from the unloading place 3 in the X direction. As a result, a space is secured in the unloading place 3.

Next, as in the case of the first H-shaped steel 90A, the lifting machine 10 is used to unload the second H-shaped steel 90B from the loading platform of the freight vehicle onto the pedestal of the second carriage 12B.
Next, by running the second carriage 12B, the second H-shaped steel 90B is brought closer to the first H-shaped steel 90A. Then, the edges of the H-shaped steels 90A and 90B are butted against each other, and the H-shaped steels 90A and 90B are temporarily fixed by joint bolts. Hereinafter, the connecting body of the H-shaped steels 90A and 90B is referred to as a long beam 90.

Next, the H-shaped steels 90A and 90B are conveyed to the side of the skeleton 1 by running the carriages 12A and 12B. At this time, the roller conveyor 13A and the roller conveyor 23A position the carriages 12A and 12B so that the roller conveyor 13B and the roller conveyor 23B are aligned.

Next, as shown in FIG. 7, by transporting the pedestals 95A and the H-shaped steels 90A and 90B by the roller conveyors 13A and 13B, the H-shaped steels 90A and the pedestal 95A are transferred to the roller conveyor 23A, and the H-shaped steels 90B and the pedestal. Is transferred to the roller conveyor 23B.

Next, the peeling (camber) of the long beam 90 is adjusted by a jack or the like. After the pedestals 95A and the H-shaped steels 90A and 90B are replaced, the trolleys 12A and 12B may be moved to the unloading area 3 to start unloading the next H-shaped steels 90A and 90B.

After adjusting the peeling, the edges of the temporarily fixed H-shaped steels 90A and 90B are welded together.

Next, the long beam 90 is conveyed by the roller conveyors 23A and 23B toward the guide columns 41A and 41B and the skeleton 1. As a result, the long beam 90 is positioned below the lifting devices 32A and 32B.

Since the carriages 12A and 12B and the roller conveyors 13A, 13B, 23A and 23B are used as described above, the H-shaped steels 90A and 90B can be conveyed and joined even in the narrow area 2.

Next, the main rope support 92 (see FIG. 1) and the main rope (not shown) are attached to the long beam 90.

Next, as shown in FIG. 8, two suspension balances 51A are attached to the guide columns 41A by the slider 52A, the upper suspension balance 51A is positioned on the long beam 90, and the lower suspension balance 51A is lengthened. It is located below the beam 90. Then, these suspension balances 51A are connected by two flexible wire rods 54A. At this time, since the flexible wire rods 54A are arranged on both sides of the long beam 90 in the width direction, the long beam 90 is surrounded by the upper and lower suspension balances 51A and the flexible wire rods 54A on both sides.

Similarly, by attaching two suspension balances 51B to the guide columns 41B and connecting these suspension balances 51B with two flexible wire rods 54B, the long beam 90 is attached to the upper and lower suspension balances 51B and both sides. Surrounded by flexible wire 54B.

Next, the suspension balance 51A on the upper side of the long beam 90 is hung on the hook 34A by the sling 58A. The same applies to the other upper suspension balance 51B.
Next, the temporary fixing of the pedestal 95A and the long beam 90 is released.
Then, as shown in FIG. 9, the lifting balances 51A and 51B are lifted by the lifting devices 32A and 32B, and the long beam 90 is lifted while being hung on the hanging balances 51A and 51B below the suspension balances 51A and 51B. The ascending distance of the long beam 90 shall be about the height of the long beam 90 or more and the length of the flexible wires 54A and 54B or less.

(2) Preparation, transportation and lifting of the second and subsequent long beams In the same manner as in the case of the first long beam 90, the H-shaped steels 90A and 90B for the second long beam 90 are unloaded. Together with joining them, as shown in FIG. 10, the second long beam 90 is conveyed below the first long beam 90.

Then, as shown in FIG. 11, new next suspension balances 51A and 51B are attached to the guide columns 41A and 41B, and the suspension balances 51A and 51B are positioned below the second long beam 90. Next, the upper suspension balances 51A and 51B of the second long beam 90 (the first long beam 90 is placed on these suspension balances 51A and 51B) and the lower suspension balance 51A, 51B is connected by flexible wire rods 54A and 54B. Then, as shown in FIG. 12, the lifting equipment 32A, 32B lifts the second long beam 90 together with the first long beam 90, and the second flexible wire rod 54A, 54B from the top and the third from the top. The second long beam 90 is suspended under the first long beam 90 by the second suspension balances 51A and 51B.

The third and subsequent long beams 90 are also manufactured, transported, and lifted in the same manner to increase the bulk of these long beams 90 from below (see FIG. 13).

During the stacking work of the plurality of long beams 90 as described above, the tower crane can be used for other purposes (for example, lifting of exterior materials and the like). Therefore, it is possible to shorten the construction period of the building and reduce the construction cost.
Further, since the stacking device is used, a plurality of long beams 90 can be temporarily placed in the narrow area 2 before being lifted by the tower crane.

(3) Load Receiving After stacking a plurality of long beams 90 from below as described above, as shown in FIG. 14, a plurality of supports (for example, for example) are placed on the ground below the long beams 90. A height-adjustable jack) 96 is installed. Here, the installation location of the support base 96 is between or beside the roller conveyors 23A and 23B, and the upper surface of the installed support base 96 is higher than the upper surface of the roller conveyors 23A and 23B. In FIG. 14 and FIG. 15 below, the roller conveyors 23A and 23B and the carriages 12A and 12B are not shown in order to make the support base 96 easier to see.

Next, as shown in FIG. 15, the long beams 90 are stacked on the support base 96 by lowering them by the lifting devices 32A and 32B. As a result, the load of these long beams 90 is transferred from the lifting devices 32A and 32B to the ground via the support base 96. Here, the lowermost long beam 90 is placed on the support base 96, the long beam 90 and the suspension balances 51A and 51B are alternately stacked on the support base 96, and the lowermost long beam 90 supports it. It is placed on the table 96, and the lowermost suspension balances 51A and 51B are suspended. The lowermost suspension balances 51A and 51B may be placed on the support base 96, and the long beams 90 and the suspension balances 51A and 51B may be alternately stacked on the lowermost suspension balances 51A and 51B.

Since the suspension balances 51A and 51B are supported by the guide columns 41A and 41B, it is possible to suppress the collapse of the long beams 90 and the suspension balances 51A and 51B that are alternately stacked.

When the stacked long beams 90 are left in place for a long time, the load of the long beams 90 is maintained in a state of being received by the ground via the support base 96.

The long beams 90 may be placed on the roller conveyors 23A and 23B without using the support base 96, and the load of these long beams 90 may be transferred to the ground via the roller conveyors 23A and 23B. .. Further, the roller conveyors 23A and 23B may be temporarily retracted so that the load of these long beams 90 can be directly transferred to the ground in the narrow region 4.

3. 3. Lifting (removal) of long beams
When the load of the stacked long beams 90 is received by the lifting devices 32A and 32B, the load of these long beams 90 is applied from the lifting devices 32A and 32B via the support base 96 as described above. And replace it with the ground (see Fig. 15).

Next, as shown in FIG. 16, after slinging the uppermost long beam 90 on the hook block 99 of the tower crane, the uppermost suspension balances 51A and 51B and the flexible wire rods 54A and 54B below them are placed above. Remove from the second suspension balances 51A and 51B. The removed suspension balances 51A and 51B and the flexible wire rods 51A and 51B are lowered to the ground by the lifting devices 32A and 32B and the second lifting devices 97A and 97B. In addition, the main rope support 92 is removed from the long beam 90 on the uppermost stage.
Next, as shown in FIG. 17, the uppermost long beam 90 is lifted by a tower crane. At this time, in order to prevent the long beam 90 from rotating, the long beam 90 is raised along the guide wire 98.
After that, in the same manner, the remaining long beams 90 are also lifted in order from the top.

(5) Since the suspension balances 51A and 51B are guided up and down by the guide columns 41A and 41B, the long beam 90 can be lowered in a stable posture. Therefore, a laminated body in which the long beam 90 and the suspension balances 51A and 51B are alternately stacked on the support base 96 can be stably formed, and the collapse of the laminated body can be prevented.

(6) By transferring the load of the stacked long beams 90 from the lifting devices 32A and 32B to the support base 96, these long beams 90 can be lifted in order from the top.

(7) Since the lifting machine 10 is installed at the unloading place 3, it is possible to unload the H-shaped steels 90A and 90B without using a tower crane.

(8) Since the rail 11, the carriage 12A, and the carriage 12B are installed, the H-shaped steels 90A and 90B can be easily conveyed in the X direction. In addition, the edges of the H-shaped steels 90A and 90B can be easily butted against each other.

(9) Since the roller conveyors 13A and 13B are installed on the carriages 12A and 12B, the long beams 90 can be easily replaced from the carriages 12A and 12B to the roller conveyors 23A and 23B.
