In the method of lifting the unit room at the bottom of the unit room (Patent Document 1, etc.), when the unit room is suspended at a predetermined position of the building, the engagement part is between the wall or a narrow part such as a corner. May be placed. Then, it is difficult to remove the wire rope from the engaging portion.
In a method of lifting by attaching an engaging portion to the upper end portion of a unit room (Patent Document 2, etc.), it is necessary that the unit room in a suspended state can withstand its own weight. In Patent Document 2, a ladder shape is formed on the outer surface of the unit room. Reinforcing members are installed and reinforced. Such reinforcement is necessary only during lifting, and is unnecessary after hanging. Nevertheless, it is wasteful to provide a large reinforcing member.
The method of hanging the wire rope around the upper and lower sides of the unit room is unstable because the posture of the unit room may collapse.
The present invention has been made in view of such circumstances, and a unit room such as a unit bath can be stably lifted, and the hanging portion is arranged in a narrow space when suspended. However, it is an object of the present invention to provide a lifting structure in which a lifting jig such as a wire rope can be easily removed from the engaging portion, and it is not necessary to provide a lifting reinforcing member that is useless after hanging. .

In order to solve the above problems, the present invention is a lifting structure for connecting a unit room to a lifting machine and lifting the unit room,
A lifting jig suspended from the lifting machine;
An engaging portion provided at the bottom of the unit room, capable of engaging with a lower end of the lifting jig and capable of remotely releasing the engaging from the room of the unit room;
It is provided with.

  According to this lifting structure, the bottom of the unit room can be supported and stably lifted by engaging the lifting jig with the engaging part at the bottom of the unit room. When the unit room is suspended at a predetermined position in a house, etc., even if the engaging part is placed between the wall or floor or in a narrow place such as a corner, the unit room is lifted remotely or from the room of the unit room. The engagement between the tool and the engagement portion can be released, and the lifting jig can be removed away from the unit room. The term “remote” means that the engagement release operation can be performed from a position away from the engagement portion. Furthermore, it is not necessary to provide a lifting reinforcing member in the unit room, which is unnecessary after the suspension.

The engagement portion is rotatable around a rotation axis orthogonal to the bottom surface of the unit room, and is unidirectional around the rotation axis by a release jig inserted from the side of the unit room to the bottom of the unit room. The lower end portion of the lifting jig may be releasable from the engaging portion by the rotation of the engaging portion in the one direction.
As a result, when the unit room is suspended at a predetermined position in a house or the like, since the engaging part is arranged between the floor and the floor, it is possible to remove the release jig even if the hand does not reach the engaging part directly. The lifting jig can be remotely released from the engaging portion by operation. As a result, the lifting jig can be separated from the unit room.

An opening / closing part that can be opened and closed from the room is provided at the bottom of the unit room, and the engaging part may be arranged so as to face the lower side of the opening / closing part.
As a result, when the unit room is suspended at a predetermined position in a building such as a house, even if the engaging part is arranged in a narrow space, the lifting and lowering unit can be opened by opening the opening / closing part from the room of the unit room. The engagement between the tool and the engagement portion can be released, and as a result, the lifting jig can be separated from the unit room.

The lifting jig includes a hanging rod extending vertically, and an upper end portion of the hanging rod is positioned above the vicinity of an upper end portion of the unit room, and a lower end portion of the hanging rod is engaged with the engaging portion. The engagement between the lower end portion of the suspension rod and the engagement portion may be released by being attached and rotating the suspension rod in one direction around its own axis.
As a result, when the unit room is suspended at a predetermined position in a building such as a house, the hanging rod is located near the upper end of the unit room or above the unit room even if the engaging portion is arranged in a narrow space. By turning, the lifting jig can be separated from the engaging portion and thus the unit room.
It is preferable that the lower end portion of the suspension rod and the engaging portion are screwed together.
More preferably, a male screw is formed at a lower end portion of the suspension rod, a female screw is formed at the engaging portion, and the male screw is screwed into the female screw.

A through hole is formed in the lower part of the wall of the unit room, the pinning member attached to the bottom of the unit room so that the engaging part covers the through hole from the outside, and the unit A locking pin that is detachably fastened to the pinning member through the through hole from inside the room, and a lower end portion of the lifting jig may be engageable with the locking pin.
As a result, when the unit room is hung at a predetermined position in a building such as a house, even if the engaging part is arranged in a narrow place, it is lifted by pulling out the locking pin from the room of the unit room. The engagement between the jig and the engagement portion can be released.

  According to the present invention, a unit room such as a unit bath can be stably lifted. Even when the engaging part is arranged in a narrow space when suspended, the lifting jig can be easily detached from the engaging part. In addition, it is not necessary to provide a lifting reinforcing member.
