Next, the raising method of the said construction apparatus 3 using the intermediate | middle frame 12 of this invention is shown below. The construction device 3 is supported by the horizontal member 2b of the building 1 by projecting the lower cannula 5 during normal construction work, and is positioned one step higher than the horizontal member 2b by projecting the upper cannula 4 It is being fixed to the said building 1 by being supported by the horizontal member 2a arrange | positioned in (refer FIG. 4-A).
[0026]
In this state, after the process of extending the building 1 upward is completed, the construction device 3 pulls the lower kanuki 5 away from the horizontal member 2b (see FIG. 4-B), and When the hydraulic jack 7 is shortened and the lower cannula 5 reaches the position of the intermediate connecting beam 15b arranged below the intermediate frame 12 (see FIG. 4-C), the lower cannula 5 retracted earlier is removed. By making it protrude again, it is connected and supported by the bracket 17 protruding from the intermediate connecting beam 15b (see FIG. 4-D).
[0027]
Thereafter, the upper cannula 4 is pulled in and removed from the horizontal member 2a (see FIG. 4-E), and the hydraulic jack 7 is extended so that the upper cannula 4 is disposed above the intermediate frame 12. When the position of the beam 15a is reached (see FIG. 4-F), the upper cannula 4 that has been retracted is protruded again and is connected and supported by the bracket 17 protruding from the intermediate connecting beam 15a (FIG. 4-G). reference). By repeating these operations, the construction device 3 moves up the building 1. After the upper cannula 4 of the construction apparatus 3 reaches the horizontal member 2 of the building 1, the intermediate frame 12 is now raised relative to the building 1.

[0029]
When the intermediate frame 12 is raised, the bracket 17 protruding from the intermediate connecting beams 15a and 15b is stored in the intermediate connecting beams 15a and 15b in advance.
[0030]
In this state, the lower cannula 5 is detached from the horizontal member 2b while the upper cannula 4 is connected to and supported by the horizontal member 2a, and is the same as the connecting beam 14b disposed below the intermediate frame 12. The construction device 3 and the intermediate frame 12 are integrated by connecting to the outer surface of the vertical member 13 at the height position or the connecting bracket 16a of the same height through fastening means such as bolts (see FIG. 5-B). . Further, when the hydraulic jack 7 is shortened and the intermediate connecting beam 15a of the intermediate frame 12 rising integrally with the lower cannula 5 reaches the position of the horizontal member 2a of the building 1 (see FIG. 5-C), the coupling bracket 16b provided at the lower part of the intermediate connecting beams 15a, 15b is supported by the horizontal members 2a, 2b (see FIG. 5-D). Thereby, the upper member 4 of the construction device 3 and the coupling bracket 16b of the intermediate frame 12 are connected and supported by the horizontal member 2a.
[0031]
In this state, after separating from the connecting beam 14b, the lower cannula 5 is drawn (see FIG. 5-E), and the hydraulic jack 7 is extended downward. When the lower kanuki 5 reaches the height of the intermediate connecting beam 15b disposed below the intermediate frame 12, the lower kanuki 5 is placed on the outer surface of the vertical member 13 at the same height as the intermediate connecting beam 15b, or The connecting bracket 16a having the same height is connected via a fastening means such as a bolt, and the construction apparatus 3 and the intermediate frame 12 are integrated again (see FIG. 5-F). Again, the climbing mechanism 6 was shortened to raise the intermediate frame 12 integrated with the lower kanuki 5, and the connecting beam 14 a disposed above the intermediate frame 12 reached the horizontal member 2 of the building 1. At that time, the coupling brackets 16a provided on the connecting beams 14a and 14b of the intermediate frame 12 are connected and supported to the horizontal members 2 and 2a of the building, respectively (see FIG. 5-G).
[0032]
In this way, the construction apparatus 3 uses the intermediate frame 12 to raise the building 1 and repeats raising the intermediate frame 12 when it reaches the upper end of the intermediate frame 12, so that the construction has been completed sequentially. It is located above the building 1.
[0033]
In the embodiments of the present invention, wherein arranged on the intermediate frame 12 intermediate connection beams 15a, 15b is horizontal members 2,2a building 1, 2b height position of the arrangement interval L ₄ 2 divides the However, the present invention is not limited to this, and when the arrangement interval L _{4 of the} horizontal members 2, 2 a, 2 b is large, the intermediate connecting beam 15 a is positioned at a height that divides the arrangement interval L ₄ into a plurality of parts. , 15b may be fixed.
[0034]
In addition, the present invention is not limited to the above-described embodiment, and it goes without saying that the configuration of each part and the details of the construction procedure can be appropriately changed according to the form and scale of the building to be constructed.
[0035]
According to the above-described configuration, the construction apparatus 3 is lifted by obtaining a reaction force from the building 1 and the intermediate frame 12, so that the arrangement intervals of the intermediate connecting beams 15a and 15b of the intermediate frame 12 are appropriately matched. Thereby, since the stroke of the climbing mechanism 6 is not affected by the arrangement interval L ₄ of the horizontal members 2, 2 a, 2 b arranged in the building 1 to be constructed, the construction apparatus 3 is used for general purposes. It becomes possible.
[0036]
Moreover, since it is not necessary to remanufacture the climbing mechanism 6 of the construction apparatus 3 by the arrangement interval L ₄ of the horizontal members 2, 2 a, 2 b arranged in the building 1 to be constructed, it contributes to a significant cost reduction. It becomes possible.
