However, installation of a concrete product by a known installation machine requires a wide foundation width because the installation machine runs on the outside of the side wall of the concrete product. It was suitable for the construction site.

[0004] The present invention has been made in view of the problems of such a conventional concrete product installation machine, and enables reliable laying of various types of concrete products having different sizes even in a construction site with a narrow foundation width. It is intended to provide an installation system.

The lateral movement of the support slide plate 15 is adjusted by the operation of the hydraulic cylinder 18 for lateral movement of the support slide plate, and the vertical movement of the support part 2 is adjusted by the operation of the support frame lift hydraulic cylinder 23. After adjusting the position of the main shaft 31 so that it can enter the
Is moved in the direction of the concrete product C previously placed on the mounting table D having a smaller width and thickness than the concrete product C by operating a truck crane (see FIG. 5A). Next, the carriages 1a and 1b of the transport unit 1 are placed on the mounting table until the positioning piece 141 of the slide plate 14 placed on each of the carriages 1a and 1b abuts on the end of the concrete product C on the side of the convex portion C2. D enters the gaps E, E at the lower end portions of the concrete product C formed by D.
At this time, each carriage 1a is near the end of the concrete product C,
It protrudes from the leading end portions 11a and 11b of the base member 1b with an appropriate length shifted (see FIG. 5B).

After the mounting plate 34 is connected to the concrete product C, the slide plate 14 is slightly raised by operating the slide plate lift hydraulic cylinders 17 and 17 via the hydraulic unit 4 so that the concrete plate C is moved from the mounting table D to the concrete plate C. The product C is pushed up and separated (see FIG. 6A). Thereafter, the transport unit 1 is driven to retract the concrete products C together with the carriages 1a and 1b from the mounting table D, and then the slide plate lift hydraulic cylinders 17 and 17 are operated again via the hydraulic unit 4, whereby The concrete product C is lowered and placed by returning the slide plate 14 to the original position (see FIG. 6B).

Subsequently, the concrete product C
Is moved to a predetermined installation location, for example, the location of the concrete product C1 previously laid (see FIG. 7) and stopped.

Thereafter, the slide plate lift hydraulic cylinders 17, 17 are actuated again to adjust the lateral movement of the slide plate 14 while adjusting the protrusion C provided on the concrete product C.
2 is adjusted to a position where it fits into the concave portion C3 provided in the concrete product C1, and the transport portion 1 is further advanced to move the projecting portion C
2 is fitted into the concave portion C3. The operation of the hydraulic cylinder 18 for moving the support slide plate laterally and the lift hydraulic cylinder 23 and the operation of the spindle feed device 24 via the hydraulic section 4 are performed, and the position of the spindle 31 is adjusted to perform concrete product C.
