As shown in FIGS. 5 and 6, the plate piece 34 is made of an elongated steel plate having a length shorter and a width wider than that of the plate body 30. The plate piece 34 extends in the longitudinal direction (vertical direction) of the plate body 30 and partially faces the other end portion (upper end portion) 30b (FIG. 3) of the plate body 30. More specifically, a part of the plate piece 34 faces the other end (upper end) 30b of the plate body 30, and the remaining part extends above the other end (upper end) 30b of the plate 34. There is.

The plate piece 34 has two holes 48, 50 provided so as to be spaced apart from each other in the longitudinal direction (vertical direction) thereof. One of the two holes 48, 50 allows the shackle 18 (FIG. 6), which is a slinging tool, to be inserted, and more specifically, the pin 18a of the shackle 18 to be inserted. Further, the other hole 50 of the plate piece 34 faces the hole 44 of the plate body, and allows the rod-shaped body 32 to be inserted.

The other hole 50 of the plate piece 34 has a round hole (not shown) having the same diameter as the hole 44 of the plate body 30, that is, a diameter slightly larger than the shaft portion of the bolt 32a described later constituting the rod-shaped body 32. It may consist of a round hole, or, as in the illustrated example, it may consist of a large diameter portion 50a and an oval-shaped small diameter portion 50b connected thereto. As seen in FIG. 5, the large diameter portion 50a is located above the small diameter portion 50b, and the small diameter portion 50b extends downward from the large diameter portion 50a.

The large diameter portion 50a has a size that allows insertion of the bolt and nut assembly constituting the rod-shaped body 32, that is, a diameter slightly larger than the head of the bolt 32a and the nut 32b of the bolt and nut assembly. .. On the other hand, the small diameter portion 50b has a width dimension and a diameter slightly larger than the shaft portion of the bolt 32a.

The plate piece 34 more preferably has an elongated hole 52 provided between the two holes 48, 50 and extending from one of the holes 48, 50 toward the other in the vertical direction as seen in FIG. The elongated hole 52 allows the insertion of the bolt and nut assembly 42 that fastens the plate piece 34 to the ceiling beam 24 of the building unit 12. According to this, the plate piece 34 can be kept in a state of being partially superposed on the plate body 30.

In the illustrated example, the rod-shaped body 32 of the lifting aid 10 comprises a bolt and nut assembly, that is, a bolt 32a and a nut 32b screwed onto the bolt. The bolt 32a is passed through the hole 44 of the plate body 30 and the other hole 50 of the plate piece 34 from the inside side to the outside side of the building unit 12 at the shaft portion thereof, and is passed through the plate body 30 and the plate piece 34. It is held so as to be orthogonal to these. The nut 32b is screwed onto the shaft of the bolt 32a on the outer side of the building unit 12 and faces the plate piece 34. The bolt 32a in the assembly of the bolt and the nut constituting the rod-shaped body 32 may be made of a pin bolt.

It rises with respect to the rod-shaped body 32. With the ascent, the bolt and nut assembly 42 relatively moves from the upper end to the lower end of the elongated hole 52 of the plate piece 34, and the rod-shaped body 32 has a large diameter of the hole 50 at the shaft portion of the bolt 32a. It moves from the portion 50a to the small diameter portion 50b, and further descends in the small diameter portion 50b toward the lower end thereof (FIGS. 5 and 6).

At this time, the entire weight of the building unit 12 is applied to both the floor beam 22 and the ceiling beam 24 of the building unit 12 via the four suspension assisting tools 10. Therefore, the load borne by the ceiling beam 24 and the deflection generated in the ceiling beam 24 are smaller than in the case where the building unit 12 is lifted only through the ceiling beam 24. For this reason, the suspension assisting tool 10 contributes to the prevention of peeling or tearing between the ceiling beam 24 and the interior 28 due to the suspension of the building unit 12.

As shown in FIGS. 7 and 8, instead of the above-mentioned example in which the holes 44 made of round holes and the holes 50 made of both large and small diameter portions 50a and 50b are formed of the plate body 30 and the plate piece 34, respectively. It can be a plate piece 34 and a plate body 30. According to this, the plate piece 34 is provided with a hole 50 formed of a round hole, and the plate body 30 is provided with a hole 44 formed of a large diameter portion 44a and a small diameter portion 44b.

In the examples shown in FIGS. 7 and 8, the shaft portion of the bolt 32a of the bolt and nut assembly constituting the rod-shaped body 32 is the large diameter portion 44a of the hole 44 of the plate body 30 and the hole of the plate piece 34. It is passed through the 50 and the nut 32b is screwed into the shaft portion of the bolt 32a. As a result, the rod-shaped body 32 is held by the plate body 30 and the plate piece 34 so as to be orthogonal to them. At this time, the assembly 42 of the bolt and the nut is passed through the elongated hole 52 of the plate piece 34, and the plate piece 34 is placed in a state of being overlapped with the plate body 30.

The plate piece 34 rises with respect to the building unit 12 during the subsequent lifting work of the building unit 12, and the shaft portion of the bolt 32a relatively moves from the large diameter portion 44a of the hole 50 of the plate piece 34 to the small diameter portion 44b. Further, the shaft portion of the bolt 42a and the nut 42b of the bolt and nut assembly 42 move from the upper end to the lower end of the slot 52 (FIG. 8). Next, the building unit 12 is lifted via the plate piece 34.

As another example of the suspension assisting tool, a plate body (not shown) that is releasably fixed to the floor beam 22 and the ceiling beam 24 of the building unit 12 and a rod-shaped body fixed to the plate body (FIG. (Not shown) and can be provided. Here, the plate body is the same as the plate body 30 shown in the figure except that it does not have a hole 44. Further, the rod-shaped body is preferably composed of a pin with a head, a bolt or the like (not shown), and is fixed to the plate body 30 by welding the tip end portion of the shaft portion to the plate body to the plate body. Are orthogonal. According to this, the building unit 12 can be suspended by directly hooking the pin 18a of the shackle 18 on the rod-shaped body.

The hanging auxiliary tool according to the other example is slightly smaller than the hole for inserting the pin 18a of the slinging tool, for example, the shackle 18, and the hole for inserting the rod-shaped body, and thus the headed pin, bolt, or the like. Can be provided with a piece of plate (not shown) with a hole having a large diameter in the head. However, the rod-shaped body does not prevent the pin, bolt, or the like having no head. According to this, the building unit 12 can be hung through the plate piece.
