Description

[Detailed Description of the Invention] The present invention provides a construction unit lifting device that is fixed to the upper end of each of the pillars, in order to lift a building unit structure having pillars at least four corners and a roof above the pillars. Regarding ingredients.

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,
In the case of a unit structure with a 75-sided roof that is normally lifted by a crane or the like using a lifting jig fixed to the upper ends of the pillars at the four corners, a crane hook is attached directly or indirectly to the roof that does not have sufficient strength. cannot be hooked.

Therefore, for 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 protrudes upward, and a crane wire is hooked to this. In this case, an attempt was made to place a washer using a round pipe around the long-legged bolt to reinforce the long-legged 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 in the diagonal direction of the crane's operating RK, the lower end of the bolt may be joined to the column. It had the disadvantage that parts were easily broken, making it impractical.

It is an object of the present invention to provide a lifting jig for a building unit that eliminates the above 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. , a step-shaped seat body having a plurality of legs that cover the corners of the upper end of the column from the outside and an earthen wall with a bolt through hole in the center; and a lower end having a lifting part at the upper end. and a lifting bolt having a threaded portion at the top, and the seat body is placed on the top end of the column so that its legs cover the outside of the corner of the top end of the column. The above-mentioned lifting bolt is screwed and fixed to the nut fixed to the VC on the back side of the bolt fixing hole provided in the center of the fixed end face plate by inserting its threaded portion into the above-mentioned bolt through-hole 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 cross-sectional view and an exploded perspective view of the lifting jig of the present invention, and as shown in the figures, the lifting jig 1 of the present invention, a seat body 2 in the shape of a step stool, The lifting bolt 5 has a ring-shaped lifting part 3 at the upper end and a threaded part 4 at the lower end.

The seat body 2 has an upper wall I having a bolt through hole 6 in the center, and a plurality of legs 9 that cover the corners of the upper end of the column body 8, which will be described later.
Specifically, four legs 9, 9, 9.9 are formed, each of which has a vertical wall 10 connected at right angles to the cross-sectional shape and the inside of its upper end. Joined horizontal mounting section 11
It consists of

8 is one of the pillars 1 erected at the corner of the building unit structure, and the horizontal mounting portions 11, 11,
11, 11 are mounted on the corners thereof, is fixed to its upper end, and a bolt fixing hole 1 is provided in the center of this end plate 12.
3 is bored and a nut 15 is fixed to the back side of the bolt fixing hole 13 by welding or the like.

In addition, 14 in the drawing indicates the roof of the building unit structure, and the roof 14 is provided with a through hole 16.
A lifting bolt 5 is inserted into the roof 14, and only the lifting portion 3 is made to protrude above the roof 14.

As shown in the figure, it is preferable that the height of the seat body 2 is approximately equal to the distance between the upper end of the column 8 of the building unit structure to be lifted and the roof 14 surface.

In order to fix the seat body 2 configured as described above to the column body 8, the legs 9 of the seat body 2 are fixed. ! 9,9. At 5, place the horizontal mounting part 11 of the seat body 2 on the column 8 so as to cover the outside of the upper corner of the column 8 at d.
, and then the lifting bolt 5 is inserted into the bolt through hole 6 of the seat body 2 and the bolt fixing hole 1 of the end plate 12.
3, and screw the threaded part 4 of the lifting bolt 5 into the nut 15.
Just screw it in and fix it.

When fixed in this way, the column 8, the seat 2, and the lifting bolt 5 become extremely sturdy, as if they were integrated.
Even if a plurality of lifting parts 3 protruding from the roof 14 are hooked onto crane hooks to lift the building unit structure, and each lifting part 3 is pulled diagonally upward at that time, stress concentration is unlikely to occur, and the lifting is easy. The bolt 5 can be made difficult to break.

After the building unit structure is lifted and placed in place as described above, the lifting bolts 5 are removed and the through holes 16 in the roof 14 are closed by appropriate means.

As described above, since the lifting jig for a building unit of the present invention can be integrally fixed to the column of the building unit structure, there is no risk of π breakage during use, and the seat body is attached to the lower wall. Because it is hollow and does not have any holes, it has the effect that even if mounting hardware such as ceiling material is installed at the top of the column, it will not affect the placement of the seat, and its practical value is extremely high. be.
