But along the frame 24, the upper and lower steel beams 10,
In addition to being able to move horizontally in the direction perpendicular to 10,
By driving the frame drive device 26, the beam 10,
It can move horizontally in the direction of extension of 10.

On the other hand, the truck body 20 of the traveling truck 12 includes:
A moving frame 40 is provided inside the moving frame 40 so as to pass through the longitudinal direction of the fourth moving frame 40.
With a mechanism as shown in Figures a and b, it is now possible for the traveling cart 12 to sandwich one of the protruding steel beams 10, 10 and place it between the other adjacent beams 10a, 10b. There is.

That is, the moving frame 40 is connected to the truck body 20.
It is formed into an elongated rectangle with a width smaller than the width of the trolley body 20, and is inserted into a rectangular through hole 42 formed in the longitudinal direction of the trolley body 20, and has extensible legs 4 at both ends thereof.
4 and 44 are fixed to each other, and racks 46 and 46 are carved along the longitudinal direction approximately at the center of both sides of the movable frame 40.

Note that FIGS. 4a and 4b show one end side of the moving mechanism of the moving frame 40.
The other end side is also equipped with a similar mechanism.

Next, a method for assembling the laying material 16 between the beams using the inter-beam laying material assembling apparatus having the above-described configuration will be described based on FIGS. 5 and 6.

First, with the frame 28 of the gripping device 18 retracted, the frame drive device 26 and the gripping device drive device 38 are driven so that the frame drive device 26 and the gripping device drive device 38 are positioned at the center of the laying material 16 loaded on the trolley body 20. After that, the gripping frame drive section 32
With this, the frame material 28 is stretched out, the part 36 attached to the frame body 34 is pressed against the upper surface of the laying material 16, and one piece of this is gripped, and the frame material 28 is contracted again (see FIGS. 5a and 5d).

Next, the frame driving device 26 is driven to horizontally move to the front of the trolley body 20 while gripping the laying material 16 (see FIG. 5b).

The above operations are the same regardless of the installation location of the laying material 16, which will be described below. When the laying material 16 is to be assembled at the location I shown in FIG.
When assembling in the location shown or,
The frame material 28 may be expanded after being moved in each direction by the gripping device drive device 38. In other words, with this assembly device, the three laying materials 16 are placed between the beams 10 and 10 without moving the traveling cart 12.
It can be assembled between the beams 10 and 10a and between the beams 10 and 10b.

In this way, between the beams 10 and 10 where the traveling trolley 12 is installed, and the beams 10a and 10a adjacent to these,
10b, when the installation of the laying material 16 is completed,
The driving device 22 moves the traveling carriage 12 backward by a predetermined distance, and the laying material 16 is assembled by repeating the above operation. The traveling truck 12 is a beam 10,
When reaching the end of 10, the carriage is moved as shown in FIG.

First, the movable frame 40 is moved in the direction of arrow A using the movable frame driving device 50 so that the leg portion 44 at the end thereof is positioned on the adjacent steel beam 10a (in this case, the distance between the leg portions 44, 44 is is set to double the beam span) The legs 4 are set so that the wheels 24 of the traveling trolley 12 are spaced apart from the beams 10
Extend 4,44.

Then, when the moving frame driving device 50 is further driven, since the moving frame 40 is fixed to the beams 10a, 10, in this case, the traveling carriage 12
will move in the direction of arrow A, and traveling trolley 1 will move in the direction of arrow A.
2 is positioned on the beam 10 and the adjacent beam 10a, and then the legs 44, 44 are retracted, and by repeating this operation, the traveling trolley 12 can be moved between the beam 10c and the beam 10d, The laying material 16 is placed between the beams 10a to 10c and between the beams 1 by the above-described operation again.
It can be assembled between 0c and 10d and between beams 10d and 10e.

Now, in the case of the inter-beam laying material assembling device having the above-mentioned configuration, it is possible to assemble the laying material 16 between the beams without manual intervention, which speeds up the work and also allows for installation in high places where personal accidents occur frequently. This makes assembly work safer and improves economic efficiency by shortening the construction period.

Further, since the installation of the laying material 16 is performed mechanically without manual labor, the installation position can be accurately uniformized.

Furthermore, each drive device 22, 26, 32, 38, 50 used for the above-mentioned assembly operation moves the traveling cart 12 on the beam 10 by remote control using wireless control or by combining various sensors and stepping motors. It is also possible to numerically control the amount or the amount of horizontal movement of the gripping device 18, and it is possible to further improve the accuracy of assembling the laying material 16 and the safety of the assembling work.

7 to 10 show other embodiments of the invention.

Only the features of the inter-beam laying material assembling device shown in the figure will be described below.

That is, the bogie main body 20 of the traveling bogie 12 has struts 60, 60 .
The frame 24 is fixed to the lower side of the frame member 62 so as to be perpendicular to the longitudinal direction, and the gripping device 18 is attached to the frame 24 via a gripping device drive device 38.

In the assembly device having the above-described configuration, the laying material 16 loaded on the trolley body 20 is as shown in FIG.
As shown in ~c, by driving the gripping frame drive unit 32 and the gripping device drive device 38 in the same manner as in the first embodiment described above, it is assembled onto the steel beams 10, 10 in the front and rear direction of the traveling trolley 12. At the same time, the traveling truck 12 can be moved along the beams 10, 10, and the traveling truck 12 can be moved between adjacent beams by the moving frame 40 installed in the truck body 20, and the beams can be laid one by one between the beams. The material 16 can be assembled.

Now, the laying material assembling device configured in this way can also achieve the same effects as the above-mentioned embodiment, and although the device of this embodiment is slightly less assembling efficiency than the above-mentioned embodiment. , the frame drive device 26, etc. are not required, so the device can be made smaller.

In the above embodiment, a suction cup-shaped part 36 is shown as a means for gripping the laying material 16, but the present invention is not limited to this, and for example, an electromagnet or a mechanical hand can also be used.

Further, the running wheels 23 that are rotationally driven along the upper surfaces of the steel beams 10, 10 are equipped with a removable safety device that is locked to the side surfaces of the beams 10, 10. It is also possible to prevent it from falling off the top surface.
