[0032]

Next, a description will be given of a method of using the transport and building apparatus.

<A> Transportation of Materials As shown in FIG. 3, a transportation / building apparatus in which a plurality of materials 10 such as H steel are mounted on a receiving table 33 of a truck 30 is transported on a track 20 and transported to a site. I do. During transportation of the material 10, the tilting column 40 is laid on the carriage 30 side.

<B> Material Transfer When the transport and erection device arrives at the site, the track device 20 holds the clamp device 32 shown in FIGS.

The mounting surface 4 of the tilting column 40 is as follows.
The material 10 is placed on 4. The access plates 46a, 46a shown in FIG. 4 are retracted from the mounting surface 44 of the tilting column 40 so as not to be in the way when the material 10 is mounted. In this state, as shown in FIG. 3, the material 10 on the receiving table 33 is translated and placed on the placing surface 44 of the tilting column 40.

After the material 10 is transferred to the mounting surface 44, as shown in FIG.
0 to protrude outward from the mounting surface 44 to restrain the material 10 from moving laterally. Further, as shown in FIG. 1, the cableway 56 extending from the crane 50 located at the tip of the tilting column 40 is connected to the tip of the material 10. Connect to the unit.

<C> Raising the Material When the placement of the material 10 is completed, the tilt cylinder 42 is extended as shown in FIG. 1 to raise the tilt column 40 almost vertically. While the material 10 is raised, even if the cableway 57 is cut, the material 10 is supported by the mounting surface 44, the lower stopper 45, and the side stopper 46, so that there is no danger of falling.

As shown in FIGS. 2 and 7, when the material 10 is raised almost vertically, the cableway 56 is wound up and the material 1 is placed on the tilting column 40.
Float 0 slightly. Further, the operation of raising and lowering the boom 51 or
The turning table 57 is turned, and at the same time, the material 10 is inserted into the slide ruler 37 provided on the truck 30 shown in FIG. Next, the cableway 56 is extended from the hoisting machine 38 mounted on the carriage 30 side, and the material 10 is built.

[0039]

Embodiment 2 The tilting column 40 may have a function of expanding and contracting. FIG. 7 shows that the tilting column 40 is a double cylindrical body 40a, 40
0b and a plurality of pin holes 40c provided in the inner cylinder 40a.
Is selected, the stopper pin 40c is inserted from the outer cylinder 40b side to adjust the total length of the tilting column 40, or the expansion and contraction can be adjusted using a hydraulic mechanism. The present embodiment is suitable for the case where materials 10 having different total lengths are built.

[0040]

Third Embodiment In order to prevent the tilting material 10 from falling forward of the tilting column 40, a pair of arms may be additionally provided in the middle of the tilting column 40. This arm has an L-shape. The middle of the arm is pivotally supported by a longitudinal support shaft of the tilting column 40, and the bent side of each arm can be closed and opened in front of the mounting surface 44 by the expansion and contraction operation of the pair of arm base ends.

[0041]

Fourth Embodiment In the above embodiment, a case has been described in which the transport / building apparatus runs on the track 20 by itself. However, a tire traveling type or an endless traveling belt type may be applied as traveling means.

[0042]

As described above, the present invention has the following effects.

<A> Material transportation and installation can be performed by one device.

<B> Since the structure of the transporting / building device is simple, it can be manufactured at low cost and can be built with high precision.

<C> Since the material is placed on the tilting column instead of being simply lifted and raised, the work of raising the material can be performed safely and reliably. In particular, by providing the stopper on the tilting column, it is possible to reliably prevent the tilting column from dropping to the side.

<D> Since the hoisting machine constituting the crane device is arranged on the bogie side, the center of gravity can be lowered, and the work stability is improved.

<E> If the mounting surface of the tilting column on which the material is mounted is set to be equal to or less than the upper surface of the cradle, the material can be transferred by a simple operation of only moving the trolley laterally without lifting the material.
