The hoisting machine 21 has rollers 24, 24, 24, 24, ...
a Roll along the rails 6 and move along the rails 6. After being moved to a predetermined position inside the building body, the hoisting machine 21 is stopped and the material 20 is introduced to the predetermined position. For example, when a partition panel that serves as a boundary wall of the apartment 1 is used as the material 20, the partition panel (material) 20 is introduced directly below the down wall panel 12 and is the same as the down wall panel 12. Arrange them so that they are aligned with the surface.

As described above, according to the material carrying-in device of the present embodiment, the operation of hoisting the necessary material 20 and introducing it into the body of the building under construction can be automatically performed without using human hands. You can That is, it is possible to easily and efficiently introduce materials without the need for a skilled craftsman to do the work as in the past. For this reason, the introduction and construction of materials can be carried out simultaneously to improve work efficiency, reduce the burden and danger on the body of craftsmen, and reduce labor and construction costs. be able to.

Further, according to the present embodiment, as described above, the rail 6 is connected to the ceiling 10 via the beam 11, the screw bolt 18, and the connecting member 9, and the down wall panel 12, the supporting metal fitting 13, The rail 6 is connected via the connecting tool 9, and the rail 6 is supported on the ceiling 10 at many places thereof, and the receiving metal fitting 36 is attached to the inner surface of the upper end of the wall panel 3 so that Therefore, the inner portion of the wall panel 3 is connected to the wall panel 3 via the connecting member 34 and supported by the wall panel 3, and further, the bracket 31 is attached to the inner surface of the upper end of the wall panel 3, The chain 35 attached to the above is guided over the upper end of the wall panel 3 to the outside of the wall panel 3, and the tip end of the rail 6 is suspended diagonally upward by this chain 35 and supported at two places. This rail 6 posture is It is possible to reliably maintain the horizontal state so as not to bend downward with respect to the weight of 20.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and the specific constitutional requirements such as the shape of each member can be appropriately changed in practice. For example, in the above-described embodiment, an example in which the material carrying-in device is applied to the two-story apartment 1 is shown. However, if it is a building under construction at the stage where the frame of the outer shape is formed, Of course, it can be applied to other buildings. In particular, it is very effective in high-rise buildings on the second floor and above.
