FIG. 1 is a flowchart showing a method of prior lifting of a refrigerator according to an embodiment of the present invention. The advance lifting method of the refrigerator according to the embodiment of the present invention is performed by using a tower crane during the construction of the steel frame, and as shown in FIG. 1, the steel material for main installation and the steel material for temporary construction (steel material for potato loading). ), OS anti-vibration equipment, low-temperature cylinder, high-temperature cylinder, and other members are carried into the desired installation location in this order and installed. After that, the low temperature cylinder and the high temperature cylinder are connected, and the temporary steel material is removed.

FIG. 2 is a schematic view showing a state when a low temperature cylinder is carried in by a tower crane during the construction of a steel frame. FIG. 3 is a diagram for explaining the installation location of the refrigerator. For example, as shown in FIG. 2, when installing the low temperature cylinder 12 at a desired installation location (see arrow A in FIG. 2), first, during the construction of the steel frame, the tower crane 100 is used on the loading platform of the truck 102. The loaded low temperature cylinder 12 is lifted to a position higher than the desired installation location. Subsequently, the lifted low-temperature cylinder 12 is moved vertically downward from directly above the desired installation location, carried in, and installed. Further, the high temperature cylinder 14 is also carried into a desired installation location and installed in the same manner as the low temperature cylinder 12. At this time, for example, as shown in FIG. 3, when the refrigerator 10 including the low temperature cylinder 12 and the high temperature cylinder 14 is installed across the plurality of beams 104, the beams 104 on the installation floor of the refrigerator 10 are attached. Later, the refrigerator 10 (low temperature cylinder 12, high temperature cylinder 14) is carried in and installed before the beam at the position where it overlaps with the refrigerator 10 when viewed from above among the beams on the upper floor is attached.

As described above, in the advance lifting method of the refrigerator 10 according to the embodiment of the present invention, the refrigerator 10 is carried in and installed during the steel frame construction. Therefore, when the refrigerator is carried in and installed after the steel frame construction. Compared with, the construction period can be shortened significantly. Further, the refrigerator 10 is carried in and installed before the beam at a position overlapping the refrigerator 10 when viewed from above among the beams on the upper floor of the installation floor of the refrigerator 10 is attached. As a result, the refrigerator 10 can be moved vertically downward from directly above the desired installation location and carried in. Therefore, it is not necessary to pull the refrigerator 10 sideways, which facilitates the carry-in work and the installation work.

On the other hand, in the conventional method of carrying in and installing the refrigerator after the steel frame construction, beams and the like are attached above the installation location of the refrigerator, so the refrigerator can be installed from directly above the desired installation location. It cannot be carried in by moving it vertically downward. Therefore, conventionally, when installing the refrigerator at a desired installation location, it is necessary to lift the refrigerator by a tower crane and to pull the refrigerator horizontally to move the refrigerator on a predetermined floor, which complicates the carry-in work and the installation work. Met.

Hereinafter, the method of pre-lifting the refrigerator will be specifically described.
