Since the building material unit hanging jig as one embodiment of the present invention is configured as described above, various building material units 8a to 8f are lifted up as shown in FIGS. (Refer to the reference number 21).

In the present embodiment, the building material units 8a to 8c have different lengths and are suspended by four-point support (each of which is called 27 units, 36 units, 45 units).
Is. Also, the building material units 8d and 8e are both of the same length and are hung by six-point support, but the building material unit 8d has a partition 8g at the central position [54 units (27/27) ], The building material unit 8e has a partition 8h at a 2: 1 position as shown in FIG. 5 (f) [5
4 units (36/18)]. Furthermore, building material unit 8f
Is a unit such as a rooftop balcony having an L-shaped cross section.

Now, regarding the building material units 8a to 8c that perform four-point support, as shown in FIGS. 5A to 5C, both ends of the building material units 8a to 8c are respectively connected to the end eye plates 4a. , 2 sets of lower rings on the other end side eye plates 4b to 4d which are appropriately spaced from this end eye plate 4a
The building material units 8a to 8c are supported via 6 and 6 and are hung below the beam member 1.

e is suspended below the beam member 1. At this time, since the building material units 8d and 8e have a length substantially equal to the length of the beam member 1, both ends of these building material units 8d and 8e are hung according to the positions of both ends of the beam member 1. As a result, the beam member 1 is constructed as in the conventional construction material units 8d, 8e.
No more prominent.

Moreover, when each building material unit 8d, 8e is hung below the beam member 1 as shown in FIGS. 5 (d) to (f), three eye plates 4a, 4b supporting each building material unit 8d, 8e. , 4e or 4a, 4c, 4e corresponding to the crane suspension eye plates 5a, 5b, 5e or 5a, 5c, 5e, upper sling 2A, 2B,
2A are respectively locked, and a beam member 1 is made by a crane through the upper slings 2A, 2B, 2A and the master ring 3.
And each building material unit 8d, 8e is suspended. Like this 3
By locking the book upper sling 2A, 2B, 2A,
The building material units 8d and 8e supported at six points are suspended without impairing the balance and without causing deformation of the beam member 1.

As described above, according to the hanging jig of the present embodiment, each building material unit 8a to 8e is hung so that at least the left end is aligned with the position of the left end of the beam member 1 without impairing the balance. Therefore, on the left end side of the beam member 1, the beam member 1
Does not protrude beyond the building material units 8a to 8e. Therefore, as shown in FIG. 5 (a), the building material unit 8a (8b
~ 8e) and obstacles such as scaffolding 22 can be surely prevented from interfering with each other, and building material units 8a to 8e can be carried in even at a position near scaffolding 22, greatly improving the workability of carrying in. To do.

Further, in this embodiment, as shown in FIGS. 5 (d) to (f), when the building material units 8d, 8e are supported at six points, three upper slings 2A, 2B are aligned with their supporting positions. Is used, there is also an advantage that the deformation of the beam member 1 can be prevented.

Now, an example of use of the ring 6e and the hook 6g for balance adjustment in the lower ring 6 and the extension chain 7 shown in FIG. 4 will be described with reference to FIG. As shown in FIG. 6, for example, a section L as a building material unit
When a unit 8f such as a rooftop balcony is lifted, it is necessary to change the left and right lengths of the lower ring 6 in order to suspend such a building material unit 8f horizontally.

Therefore, in the present embodiment, on the right side of the lower ring 6, the hook 6g is locked to the lowermost ring 6e and three rings are attached.
While the length is shortened by loosening 6e, the extension chain 7 is locked to the lower end hook 6h without locking the hook 6g on the left side of the lower ring 6. And
By locking the hook 6h and the hook 7b at the lower end of the extension chain 7 to the building material unit 8f, the building material unit 8f is suspended while being kept horizontal.

In this way, by using the balance adjusting ring 6e, the hook 6g, and the extension chain 7, the balance of the weight of the building material unit to be suspended can be easily adjusted, and the unit 8f such as a rooftop balcony having an L-shaped cross section can be lowered. Since the ring 6 is suspended while ensuring a proper suspension angle α, the eyebolt portion (not shown) in the building material unit 8f due to the large suspension angle α is prevented from being damaged.

In the above example, the hooks 2f and 2g, the building material unit hanging eye plates 4a to 4e, the crane hanging eye plates 5a to 5e, the balance adjustment ring 6e, etc. are painted by applying an appropriate color, thereby hanging. In addition to improving the operability of the jig, it is possible to prevent work errors during balance adjustment. For example, by painting the hook 2f and the eye plate 5b in yellow and painting the hook 2g and the eye plate 5c in red, there is a mistake in working such as locking the hooks 2f and 2g to the wrong eye plates 5c and 5b. It can be prevented from occurring.

Further, in the above-described embodiment, the case where the eye plate is used as the hook metal is described, but the present invention is not limited to this, and an eye bolt, a hook ring, a hook, or the like may be used.

[Effects of the Invention] As described in detail above, according to the hanging jig for a building material unit of the present invention, it is possible to hang building material units of a plurality of lengths without impairing the balance, and at the same time, one end of the building material unit. Can be suspended according to the position of one end of the beam member, so that the beam member does not project beyond the suspended building material unit on the one end side of the beam member, and the building material unit and obstacles such as preceding scaffolding It is possible to bring in the building material unit while surely preventing the interference with each other, and it is possible to obtain an effect that the carrying-in workability is significantly improved.
