Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical conveyor for construction. More specifically, the uppermost floor of a building is constructed in advance, and the uppermost floor is raised from the bottom to the top. However, in the construction method for constructing the lower floor of the uppermost floor, the present invention relates to an elevating device for construction in which the lifting height of the elevating device that conveys building materials corresponding to the rise of the uppermost floor is variable.

[0002]

2. Description of the Related Art When constructing a high-rise building, the top floor of the building is constructed first, and the supporting pillars supporting the top floor are used as guides to raise the top floor by a jack-up device to raise the top floor. There is a construction method for a high-rise building in which a work space for building a lower floor is formed in the lower part of the building, and building materials are supplied from the above-ground portion to build the building sequentially to the higher floors.

In the construction method described above, there is a temporary unloading lift at the construction site as an elevating device for conveying building members for constructing the lower floor portion on the lowermost floor, and particularly for existing long objects. There is a so-called long lift, which lifts a rectangular loading platform between two guide rails. A hoist is installed on the ground and a wire is attached to the hoist. By being wound, the loading platform moves up and down to a predetermined height.

In addition to the above, in the construction method, an overhead traveling crane is installed at the lower part of the uppermost floor, and an electric hoist is attached to the electric trolley of the overhead traveling crane. Materials are hoisted from outside by a (hoist), horizontally moved by an overhead traveling crane and conveyed to a predetermined attachment position, and the same material is transferred to another attachment device and conveyed.
