As a third step, as shown in FIG. 16, with the lower hanger 11 raised to the (N-1) floor portion of the high-rise building 1, the support stopper 14 of the lower hanger 11 is moved to (N-1). 2) Placed and engaged on the beam brackets 15 on the floor portion, whereby the top floor frame 2 is supported by the beam brackets 15 on the N floor and the (N-1) floor portion.

As a fourth step, as shown in FIG. 17, the support stopper 13 of the upper hanger 10 is detached from the beam bracket 15 on the N-th floor, and the piston of the lift-up mechanism 9 is extended to extend the upper hanger. 1
0 is raised together with the cylinder of the lift-up mechanism 9 along the rail 12 fixed to the side wall portion 7 to the (N + 1) th floor portion of the high-rise building 1.

As a fifth step, the upper hanger 10
Of the (N + 1) -th floor portion of the beam bracket 15 is engaged.

The sixth step is the same as the second step shown in FIG. 15, and the above steps are repeated to raise the top floor frame 2 stepwise.

[0014]

However, in the above-described conventional method shown in FIGS.
The temporary struts 5 that support the ceiling project through the top floor frame 2 to prevent rainwater in this penetrating portion, and to construct the surrounding material of the strut sheath tube when the top floor frame is landed on the structure of the main body. Since extra work was required at the final stage of the high-rise building to be built, such as the work of replacing with a new building design member, labor saving and efficiency could not be achieved.

In addition, if the horizontal force is to be borne only by the temporary struts with respect to the horizontal force generated during the earthquake during construction, a corresponding number of the struts are required as the top-floor support struts, and there is a drawback of lack of economy and safety. .

In the conventional method of lifting up the top floor frame shown in FIGS. 13 to 17, the lift-up mechanism 9 is located on the outer wall side of the high-rise building 1, and after the lift-up is completed, the upper and lower hangers 10, 11 are lifted. Useless work will be left on the outer wall of the occupied second floor.

Further, since the top floor frame 2 is supported via the upper and lower hangers 10, 11 of the lift-up device 8, the upper and lower hangers 10, 11 and the side walls of the high-rise building 1 need to be reinforced. .

Further, as shown by an arrow in FIG. 18, the center point of the lift-up device 8 and the vertical load position acting on the top floor frame 2 when the lift-up device 2 rises are laterally shifted from each other. However, there has been a drawback in that it is not economical and safe.

The present invention has been made to eliminate the above disadvantages.

[0038]

According to the method and apparatus for lifting the top floor frame for building a structure according to the present invention, the temporary support penetrates the roof of the top floor frame as compared with the conventional case where the temporary support supports the top floor frame. Since it does not need to be performed, it is possible to easily take measures against rain, and it is possible to reduce a sheath tube at the penetrating portion and a temporary reinforcing portion around the driving portion.

Further, during normal work, the top floor frame is supported by the main columns of the high-rise building via the support stopper, and both sides of the main columns are clamped by the temporary support frames suspended from the top floor frame. Therefore, it can sufficiently resist the horizontal force generated during an earthquake, and has great advantages such as being superior in economy and safety as compared with the conventional case where only temporary supports are used.
