[0005]

In such conventional elevators and construction lifts, long supporting members 3 such as struts and guides are provided so as to penetrate from the ground floor of the frame 1 to the working floor. However, most of the temporary materials at construction sites are diverted materials, and these are often raised from the arbitrary floor above the first floor (ground floor) to the working floor or lowered from the working floor to the arbitrary floor. The frequency of using the floor is low.

Further, the opening 2 remains until these elevators and construction lifts are removed, which delays the completion of the work. The same applies to the case where an elevator or a construction lift is provided outside the skeleton 1, and the exterior finishing of the building cannot be performed only at that portion.

The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional example, to limit the equipment to the required length and to divert it, thereby eliminating the wasteful portion which is not used, and to divert the diversion.

On the other hand, the gist of the present invention is to attach detachably a locking member to the floor of the building frame to the elevator body.

As a method of using the lifting device, a rack on the side of a long supporting member such as a column or a guide is engaged with a pinion of a motor provided on an elevator body such as a cage or a loading platform so as to follow the long supporting member. In the hoisting method of hoisting with an elevator body that elevates and lowers, the long support member has a length that can span several floors of three or more floors, and the locking member that detachably locks to the building frame is long. In the middle of the length support member, a foldable top support is provided at the top, and a frame-shaped fall-prevention hardware holding the long support member can be attached to the building body side, while the elevator body is attached to the elevator body. A lifting device that detachably attaches the locking member to the floor of the building frame is used, and at the time of lifting, the long support member is locked to the building frame by the locking member and the top support to raise and lower the elevator body. , When not hoisting, lift the elevator body through the locking member Provided on the elevator body with a long support member that is locked to the building body, attaches a fall-prevention hardware, holds the long support member, and releases the locking member and the top support from the elevator body. The gist is to drive the motor to raise and lower along the extension line in the longitudinal direction.

[0010]

According to the present invention described in claims 1 and 2,
Since the long supporting members themselves such as the columns and guides can also be raised and diverted, the long supporting members have no useless portion. Further, after moving the long bearing member, by appropriately closing the dead hole, it is possible to eliminate the existence of an unworked portion and shorten the construction period.

Moreover, the elevator body is easily and quickly driven by the motor and is engaged by the engagement of the rack and the pinion as long as it is within the length range of the long bearing member having a length of several steps of three times or more. It can be lifted and lowered reliably. Further, when elevating and lowering the long supporting member, the engagement between the locking member and the floor portion of the building body of the top support is simply released, and the rack automatically and simply, quickly and accurately The support member moves up and down.

Further, when the elevator body is moved up and down, the long bearing member is not only fixed by the locking member in the middle but also firmly fixed by the top support at the top thereof, which is stable. . Furthermore, when moving the long bearing member, in addition to fixing the elevator body with a locking member,
Since the long support member is held by the frame-shaped fall-prevention hardware, the elevating and lowering on the extension line in the longitudinal direction is stable.
