Description

[Detailed Description of the Invention] The present invention is designed to lift a building unit structure that is fixed to the upper end of each of the pillars, in order to lift a building unit structure that has pillars in at least four corners and a roof on top of the pillars. Regarding jigs.

BACKGROUND OF THE INVENTION With the development of industrial production of housing, parts of housing are being produced in factories as three-dimensional units.

When installing such a unit structure,
Normally, it is lifted by a crane or the like using a lifting jig fixed to the upper end of the pillars at the four corners, but in the case of a unit structure with a roof, crane hooks are placed directly or indirectly on the roof which does not have sufficient strength. cannot be hooked.

Therefore, in such a roofed unit, a foot-long bolt is fixed to the top of a sturdy pillar, the upper end of which penetrates the roof and projects upward, and a crane wire is hooked to this bolt to lift it up. In this case, an attempt was made to place a washer using a round pipe around the long bolt in order to reinforce the long bolt.

However, even if the long-legged bolts described above are reinforced with washers, if the wire hooked to the upper end of the long-legged bolt is pulled diagonally during crane operation, the lower end of the bolt may become attached to the column. It had the disadvantage that parts were easily broken, making it impractical.

The object of the present invention is to provide a lifting jig for building units that eliminates these drawbacks.

That is, the lifting jig of the present invention is a lifting jig that is fixed to the upper end of each of the pillars in order to lift a building unit structure having pillars at at least four corners and a roof above the pillars. , consisting of a seat body consisting of an upper wall, a lower wall, and a slanted wall connecting them, and a lifting bolt having a lifting part at the upper end and a threaded part at the lower end. A through hole is provided in the center for the lifting bolt to pass through, and a plurality of fixing protrusions are provided on the lower surface of the peripheral portion of the lower wall, the ends of which are fixed to the upper end of the column. The seat body is placed on the end plate by inserting the fixing protrusions into a plurality of holes provided in the face plate corresponding to the fixing protrusions, and a through hole in the lower wall is placed in the center of the end plate. A nut fixed to the back side of a bolt fixing hole provided correspondingly to the bolt fixing hole, and the above-mentioned lifting bolt are screwed and fixed by inserting their threaded portions into the two above-mentioned through holes and the above-mentioned bolt fixing hole.

Hereinafter, an embodiment of the present invention will be described as shown in the drawings.

1 and 2 respectively show a vertical sectional view and an exploded perspective view of the lifting jig of the present invention. As shown, the lifting jig 1 includes an upper wall 2, a lower wall 3, and a connection between them. It is composed of a truncated pyramid-shaped seat body 5 made of an inclined wall 4, and a lifting bolt 8 having a ring-shaped lifting part 6 at its upper end and a threaded part 7 at its lower end.

At the center of the upper wall 2 and lower wall 3 of the seat body 5, through holes 9 and 10 are provided, respectively, through which the lifting bolts pass, and at the four corners of the lower wall 3, a plurality of fixing protrusions 11. 11
．． 11.11 is provided.

Reference numeral 12 designates one of the columns erected at the corner of the building unit structure, and an end plate 13 on which the seat is placed is fixed to the upper end thereof. A plurality of holes 14, corresponding to the fixing protrusions 11, 11, 11, 11 of 5,
14, 14, 14 are provided.

The end plate 13 further has a through hole 10 in the lower wall 3 at its center.
A nut 16 is fixed to the back side of the bolt fixing hole 15 by welding or the like.

In addition, 17 in the drawing indicates the roof of the building unit structure, and the roof 17 is provided with a through hole 18.
A lifting bolt 8 is inserted into the hole 8, and only the lifting portion 6 is made to protrude above the roof 17.

As shown in the figure, it is preferable that the height of the seat body 5 is approximately equal to the distance between the upper end of the column 12 of the building unit structure to be lifted and the roof 17 surface.

In order to fix the seat body 5 configured as described above to the column body 12, a plurality of holes 14, 1 provided in the end plate 13 of the column body 12 are used.
4, 14, 14, fixing protrusions 11, 11, 11 of the seat body 5
．． 11 respectively and place the seat body 5 on the end plate 13, and then insert the lifting bolts 8 into the through holes 9, 10 of the seat body 5.
The lifting bolt 8 may be inserted into the bolt fixing hole 15 of the end plate, and the threaded portion 7 of the lifting bolt 8 may be screwed into the nut 16 to be fixed.

If fixed in this way, the column 12, seat 5, and lifting bolt 8 will become extremely sturdy, as if they were integrated, and the lifting parts 6 protruding from the four corners of the roof 17 can be connected to the wires of the crane. When the building unit structure is hung on a hook, even if each lifting part 6 is pulled diagonally upward, stress concentration hardly occurs and the lifting bolt 8 can be made difficult to break.

After the building unit structure is lifted and placed in place as described above, the lifting bolts 8 are removed and the through holes 18 in the roof 17 are closed by appropriate means.

Note that, unlike the illustrated example, the fixing protrusion 11 is
It is also possible to provide the seat body 5 in a peripheral part other than the four corners of the seat body 5, and it is also possible to form the seat body 5 into a truncated conical shape or the like.

As described above, since the lifting jig for the building unit of the present invention can be integrally fixed to the column of the building unit structure, there is no fear of breakage during use, and its practical effects are great. It is something.
