The rollers 12, 12, 12, 18, 18 are sandwiched by a predetermined force (hereinafter, such work will be referred to as "composite member 5").
"0 is set in the sending device 10"). Further, the trolley 22 attached to the guide rail 21 is arranged in front of the delivery device 10 (direction of arrow P). Then, the sending device 10
The composite member 50 that has come out through it is further pulled out to the clamp 26 of the trolley 22, and the tip portion 50a thereof is connected and fixed to the clamp portion 26a of the clamp 26. This allows
The composite member 50 of the drum device 30 of the work table 47A is connected to the trolley 22 via the delivery device 10, and the delivery device 10
Can drive the composite member 50 housed in the drum device 30 to the trolley 22 side. Next, when the drive motor 13 of the delivery device 10 is operated to rotationally drive the delivery rollers 12, 12, 12, the composite member 50 in the delivery device 10 is carried to the rollers 12 side (in FIG. 2). The composite member 50 is sequentially drawn out from the drum device 30 while being sent in the direction of arrow G). Then, the sending device 1
Since the composite member 50 sent from 0 in the direction of arrow G pushes the trolley 22 due to its rigidity, the trolley 22 receives the force of the sent composite member 50 and moves along the guide rail 21 in the circumferential direction (direction of arrow P). ) Move to. Therefore, the composite member 50 including the PC cable 51 and the sheath tube 52, which is delivered by the delivery device 10, moves in the circumferential direction (direction of arrow P) along with the trolley 22 along the guide rail 21. Then, the composite member 50 is laid down to a predetermined position in the circumferential direction (that is, the direction in which the PC cable 51 should be laid) which is the extending direction of the guide rail 21. In other words, the composite member 50 is delivered by the delivery device 10 and the rigidity of the PC cable 51 and the sheath tube 52 forming the composite member 50 is used to cause the trolley 22 to travel on the guide rail 21 to guide the composite member 50. Then, the composite member 50 including the PC cable 51 and the sheath tube 52 is attached to the guide rail 2
1 can be laid down to a predetermined position. Then, the trolley 22 is in front of the work table 47A (direction of arrow P).
When the work table 47B is placed at, the PC cable 51 and the sheath tube 52 forming the composite member 50 are laid between the work tables 47A and 47B. Therefore, when the trolley 22 moves to the work table 47B, the drive motor 13 of the delivery device 10 is stopped. Next, the delivery device 10 installed on the installation table 49 of the work table 47A is removed from the installation table 49, transferred to the work table 47B, and installed on the installation table 49 of the work table 47B (that is, the delivery apparatus 10 is diverted). . Then, the composite member 50 is pulled out from the drum device 30 provided on the work table 47B toward the delivery device 10, and the pulled-out composite member 50 is set to the delivery device 10 that has been diverted. Further, the tip portion 50a of the composite member 50 that has come out through the delivery device 10 is moved to the work table 47B.
The second clamp 26 is connected and fixed to the clamp portion 26a.
Therefore, the delivery device 10 is operated to deliver the composite member 50, and the composite member 50 moves the trolley 22 in the circumferential direction (direction of arrow P) so that the PC cable 51 and the sheath tube 52 are guided to each other. Lay along 21.
Then, when the trolley 22 moves to the work table 47C arranged in front of the work table 47B (direction of arrow P), the PC cable 51 and the sheath tube 52 are laid between the work tables 47B and 47C. Then, when the trolley 22 moves to the work table 47C, the drive motor 13 of the delivery device 10
To stop. In this way, while the delivery device 10 is diverted and the trolley 22 is moved, the PC cable 51 and the sheath tube 52 are respectively laid in such a manner that the composite member 50 is laid between the work benches 47, 47 adjacent to each other by the delivery device 10. By repeating the laying, four worktables 47A, 47
The PC cable 51 can be laid all over B, 47C, and 47D. That is, the PC cable 51 for one round of the side wall 2 can be laid in the circumferential direction inside the sliding formwork device 40 forming the side wall 2 of the tank 1 to be constructed.

Next, after laying the PC cable 51 for one turn, the slide jacks 45 of the sliding formwork device 40 are operated by a known method, together with the support frame body 41 and the dam plates 42, 42. The workbench 47, the PC cable laying device 9, and the like are raised to a predetermined height in the form of obtaining a reaction force from the rod 46 standing upright. And the sliding formwork device 40
After finishing raising to a predetermined height, in the same manner as described above, the composite device 50 is laid between the worktables 47, 47 adjacent to each other by the delivery device 10 while diverting the delivery device 10.
By repeatedly laying the C cable 51 and the sheath tube 52, the PC cable 51 for one turn is laid in the circumferential direction in the sliding form device 40. In this way, when the laying of the PC cable 51 for one round is completed, the sliding form device 4
By repeatedly operating the slide jacks 45 of 0 to raise the working table 47, the PC cable laying device 9 and the like together with the sliding formwork device 40 to a predetermined height, the side wall 2 of the tank 1 to be constructed is In the height direction, the PC cables 51 for one round can be laid in a number of layers in the form of forming a predetermined interval in the vertical direction. The PC cable 51 for one round, that is, the four work benches 47A, 4
Although not shown, each PC cable 51 laid between 7B, 47C, and 47D is appropriately fixed in the vicinity of each work table 47 by a known method. Further, when fixing the PC cable 51, it is needless to say that by shifting the fixing position in the height direction, the PC cable 51 can be more effectively tensioned and the strength of the side wall 2 is increased.

As described above, the PC cable 51 pulled out from the drum device 30 is passed through the feeding device 10 through the trolley 22.
If the sending device 10 is operated after that, the work tables 47, 47 adjacent to each other can be operated with almost no labor.
The PC cables 51 can be laid in the form of laying the composite member 50 between them, and the PC cables 51 for one lap can be laid in the circumferential direction of the side wall 2 of the tank 1 to be constructed. Therefore, when constructing a structure having a long wall such as the side wall 2 such as the tank 1, the guide rails 21 are installed by extending in the circumferential direction such as the circumferential direction of the wall of the construct in this way. If the PC cable laying device 9 is used, labor for laying a tension cable member such as the PC cable 51 in the circumferential direction can be saved. In addition, the PC cable 51 is sent out in one direction (arrow P direction) to move the trolley 22 in one direction (arrow P).
The PC cable 51 can be continuously laid by moving the PC cable 51 and the trolley 22.
There is no wasteful work process such as pulling back in the opposite direction (arrow Q direction). Therefore, the operation of continuously laying the PC cable 51 can be performed, and the PC cable 51 can be laid efficiently. Further, the PC cable laying equipment 7 is configured such that the PC cable laying device 9 is attached to the sliding formwork device 40, so that the PC cable 51 for one round at the predetermined height of the side wall 2 of the tank 1 to be constructed. After laying the
By raising the sliding formwork device 40, the delivery device 10, the guiding device 20 and the drum device 30 which form the PC cable laying device 9 can also be raised together. That is, it is possible to raise and move these devices 10, 20, 30 to a new position in the height direction of the side wall 2 to be constructed by utilizing the raising function of the existing sliding formwork device 40 necessary for constructing the tank 1. it can. Therefore, without installing a new lifting device for lifting these devices 10, 20, and 30 forming the PC cable laying device 9 at the work site, one turn is made in the height direction of the side wall 2 of the tank 1 to be constructed. Minute PC cable 5
1 can be laid in multiple layers, which is economical.

In the above embodiment, the tank 1
Although the guide rail 21 is formed in an annular shape corresponding to the plane shape of the side wall 2 of the above, how should the guide rail members such as the guide rail 21 be formed so as to correspond to the plane shape of the wall of the structure to be constructed? Needless to say, it may have any shape, such as an elliptical ring shape, a curved shape, or a linear shape. Further, in the above-described embodiment, the PC cable 51 for one round of the side wall 2 is laid in a manner of being divided into four, but the tension cable member such as the PC cable 51 for one round is laid on the wall such as the side wall 2 to be constructed. Needless to say, it may be installed (or only the required length), and one or more pieces may be divided (that is, any number of drum devices 30 may be arranged on the sliding form device 40). Furthermore,
In the above-described embodiment, one delivery device 10 is diverted, but if it is desired to prioritize the shortening of the construction period even if the equipment cost is slightly high, the delivery device is provided for the drum device 30 provided on each workbench 47. It goes without saying that by arranging the trolley 10 and the trolley 22 respectively, the PC cable 51 can be laid in a shorter time and with less labor. That is, if applied to the example of FIG. 1, although not shown,
The drum device 3 in which the delivery device 10 and the trolley 22 are arranged below the four worktables 47, and which is provided on each worktable 47
The composite members 50 pulled out from 0 are set in the delivery device 10 and connected to the trolley 22. Then, each delivery device 10 is operated to move each trolley 22 on the guide rail 21. Then, as described above, one trolley 22
Even if the trolley 22 is not moved by one turn, each trolley 22 is moved only by ¼ turn corresponding to the arrangement interval of the drum devices 30, and the composite member 50 pulled out from each drum device 30 is moved.
Can be laid between the four work benches 47, and the PC cable 51 for one round can be laid. Therefore, it is possible to lay the PC cable 51 in a shorter time and with less labor.

Further, in the above embodiment, the work table 4
Although the delivery device 10 was installed on the installation table 49 below 7A, the delivery device 10 moved the composite member 50 in the circumferential direction (arrow P,
It may be installed in any way as long as it can be sent in the Q direction). For example, as shown in FIGS. 4 and 5, the delivery device 10 may be installed below the installation table 49. In this case, the installation table 49
Are arranged so as to be engaged with the recesses of the cross member 41a of the support frame main body 41, and the delivery device 10 uses the clamp portion 2 of the clamp 26 of the trolley 22 to set the axis of the composite member 50 to be delivered.
It is arranged below the installation table 49 so as to be as close as possible to the center of 6a (ideally, in agreement). As a result, the deviation between the axis of the composite member 50 (that is, the PC cable 51) delivered by the delivery device 10 and the center of the clamp portion 26a of the clamp 26 of the trolley 22 becomes small, so that the composite member 50 is less likely to buckle. The rigidity of the composite member 50 can be effectively utilized, and the force by which the delivery device 10 delivers the composite member 50 acts as a force to move the trolley 22 efficiently, and the composite member 50 (that is, the PC cable 5) can be more efficiently used.
1) can be laid.
