[About construction method of building using climbing crane]
A construction method of a building using the climbing crane 100 having the above-described structure will be described based on (a) of FIG. 1 to (e) of FIG.

(Overview of climbing crane)
As shown to (a) of FIG. 1, the inner mast structure 1 to which the crane main body 5 was attached is fixed to the 1st attachment mount frame 3a via the inner mast attachment part 2, and also via the 1st attachment mount frame 3a. Is fixed to the base 8. Then, as shown in (b) of FIG. 1, the outer mast structure 6 is installed around the inner mast structure 1.

(Floor climbing)
First, the second mounting base 3b is installed on the upper surface of the outer mast structure 6, and the cross beam 7 is installed on the upper surface of the second mounting base 3b.

  Next, as shown in (c) of FIG. 1, the crane main body 5 is lowered to fix the bell receiving rack 5 b and the cross beam 7. The crane main body 5 is fixed to the outer mast structure 6 by fixing the bell receiving rack 5 b to the cross beam 7. After fixing the bell receiving rack 5b, the inner mast mounting portion 2 is divided into the mounting base 2a and the legs 2b at the dividing surface 2c. In (c) of FIG. 1, although the leg part 2b divided | segmented is fixed to the 1st attachment mount frame 3a by the base frame fixing tool 4, and the state which remains as it is is shown, May be removed.

  Then, by dividing the leg 2b from the inner mast mounting portion 2, the inner mast structure 1 fixed to the inner mast mounting portion 2 is supported by the crane main body 5 and can freely move in the vertical direction. Therefore, the inner mast structure fixed to the inner mast mounting portion 2 is raised, and the leg portion 2b fixed above the second mounting base 3b is joined to the mounting base 2a. At this time, it is desirable to temporarily fix the leg portion 2 b to the upper surface of the second mounting stand 3 b by the base frame fixing tool 4. This is because by temporarily fixing the leg 2b to the base frame fixing tool 4 in advance, the alignment is facilitated at the time of joint between the mounting base 2a and the leg 2b. In addition, when the inner mast structure 1 is lifted, the position of the mounting base 2a can be adjusted so that the mounting base 2a and the leg 2b do not contact each other to cause an obstacle to floor climbing.

(Highly independent work)
As shown in (d) and (e) of FIG. 1, after fixing the inner mast structure 1 above the second mounting base 3b, the fixing of the crane main body 5 is released and the crane main body 5 is lifted. At this time, as shown in (e) of FIG. 1, the second mounting base 3b can be installed not only on the upper surface of the outer mast structure 6, but also the outer mast structure 6 is fixed to the second mounting base 3b. It is preferable to have a function (in other words, a function of jointing the outer mast structure 6 and the outer mast structure 6). This is because floor climbing can be performed multiple times by providing the function of fixing the outer mast structure 6 to the second mounting base 3b. Furthermore, the height of the climbing crane 100 can be easily adjusted.

(Structure of inner mast mounting part applicable to climbing crane)
Next, with reference to (a) to (c) of FIG. 4, another example of the inner mast mounting portion 2 applicable to the climbing crane 100 of the present invention will be described.

(Foldable legs)
In the inner mast attachment portion 2 shown in FIG. 4 (a), the foldable legs 2b are attached to the four corners of the attachment base 2a, and it is possible to open the folded and folded leg 2b into its original form. It has a simple structure. By bending the leg portion 2b to an angle at which it does not contact the second mounting base 3b, the inner mast structure 1 can be raised and lowered without contacting the inner mast mounting portion 2 with the second mounting base 3b. Further, since the leg portion 2b is not divided from the inner mast mounting portion 2, it is easy to fix the inner mast mounting portion 2 to the second mounting base 3b.

  Further, the inner mast attachment portion 2 can be moved from the first position to the second position by folding the leg portion 2b. On the other hand, a part of the leg 2b is disposed on the upper surface of the second mounting base 3b by opening the folded leg 2b so as to be in the original form. Thereby, the inner mast mounting portion 2 is arranged on the second mounting base 3b more simply by repeating the folding of the leg 2b and the opening of the folded leg 2b to be the original form. Can.

(Retractable legs)
The inner mast attachment portion 2 shown in (b) of FIG. 4 has a structure in which the leg portion 2b is accommodated inside the attachment base 2a or around the attachment base 2a. By storing the leg portion 2b when raising and lowering the inner mast structure 1, the inner mast structure 1 can be raised and lowered without contacting the inner mast attachment portion 2 with the second mounting rack 3b.

  The inner mast attachment portion 2 includes a telescopic leg 2 b disposed around the attachment base 2 a. In addition, the inner mast attachment portion 2 can be moved from the first position to the second position by the leg portion 2b being retracted (stored). On the other hand, after the leg portion 2b moves to the second position, a part of the leg portion 2b is extended and disposed on the upper surface of the second mounting rack 3b. By repeating the expansion and contraction of the leg portion 2b in this manner, the inner mast attachment portion 2 can be easily disposed on the second attachment mount 3b.

(Rotating inner mast mounting part)
The inner mast attachment portion 2 shown in (c) of FIG. 4 is provided with a leg portion 2b disposed around the attachment base 2a. Further, in the inner mast mounting portion 2, the leg portion 2b of the inner mast mounting portion 2 does not contact the second mounting base 3b from the state where the leg 2b of the inner mast mounting portion 2 contacts the second mounting base 3b. In the structure shown in the figure, it is rotated from the broken line state to the solid line state. The leg portion 2b of the inner mast mounting portion 2 does not contact the second mounting base 3b by rotating the direction of the inner mast mounting portion 2 so that the leg 2b does not contact the second mounting base 3b. Can raise the body 1 The structure in which the direction of the inner mast mounting portion 2 with respect to the second mounting base 3b is rotated is not structurally weak as in the divided surface 2c, and the strength of the inner mast mounting portion 2 can be increased.

  That is, the inner mast mounting portion 2 can rotate in the horizontal direction with respect to the first mounting base 3a. The leg portion 2b of the inner mast mounting portion 2 is mounted on the second mounting frame 3b by rotating the inner mast mounting portion 2 by 90 degrees in the horizontal direction (from the state shown by the broken line) at the arrangement position at the first position. It will be in the state which does not contact the 2nd mounting rack 3b from the state which contacted. As a result, since the leg 2b of the inner mast mounting portion 2 does not contact the second mounting rack 3b, the inner mast mounting portion 2 can be moved from the first position to the second position. In addition, by appropriately rotating the direction with respect to the first mounting base 3a in the horizontal direction, the inner mast mounting portion 2 can be easily disposed on the second mounting base 3b.
