DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of self-elevating a construction device provided over a structure under construction, and more particularly to a method of constructing a construction device while obtaining a supporting reaction force from an outer peripheral structural material of an existing structure. The present invention relates to a self-elevating method of a construction apparatus which sequentially moves upward with the construction of a structure.

[0002]

2. Description of the Related Art In recent years, construction equipment has been employed as a means for solving the shortage of labor in construction work of high-rise buildings. This construction equipment can lift and assemble structural materials,
The system is provided with a system for performing construction work such as concrete casting by organically linking an overhead traveling crane, various work robots, and the like. This system aims to automate the construction work and save labor.

As shown in FIG. 5, for example, as shown in FIG. 5, the construction apparatus 50 covers the upper part of the top floor of a structure under construction, and the work facility such as the overhead traveling crane is disposed below the construction apparatus. A climbing device provided at a lower end of the support column 54, comprising a stage 52 and a support column 54 for supporting the stage 52 by obtaining a support reaction force from an outer peripheral column member 53 of the existing structure 51 below the stage 52. 55
, The structure is successively constructed above the existing structure 51 while ascending.

That is, the climbing device 55 is provided with expansion and contraction means 56 which expands and contracts in the vertical direction, and is disposed at two upper and lower positions with the expansion and contraction means 56 interposed therebetween. 6 (a) to 6 (c), for example, as shown in FIGS. 6 (a) to 6 (c), the outer periphery of one of the upper and lower locking means 57. While maintaining the locked state to the column member 53, the other locking means 57
Is moved, and the upper and lower locking means 57 for locking to the outer peripheral column member 53 are alternately rearranged, and the construction device 50 is lifted upward by a so-called scaleworm method.

[0005]

However, in the above-described conventional climbing device 55, the construction device 50 is self-elevated by the so-called shading insect method in which the upper and lower locking means 57 are alternately changed. Since the other locking means 57 is released from the outer peripheral column member 53 and moved while maintaining the locked state of the locking means 57, one of the locking means is always used when the locking means 57 is repositioned when ascending. Stop means 5
7 is opened. Therefore, although the locking means 57 are provided at two locations above and below the expansion / contraction means 56, only one of the locking means 57 for locking to the outer peripheral column member 53 is provided.

That is, the locking by the locking means 57 is performed from the side of the existing structure 51, so that the outer peripheral column member 53 is locked.
The center axis of the support column 54 is eccentric from the center axis of the support column 54, so that a large bending moment acts on the locking portion. Therefore, in order to resist such a large bending moment in spite of one of the locking means 57 being idle, it is necessary to make both upper and lower locking means 57 large devices. There was a problem that it was not possible to efficiently resist such a bending moment.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to efficiently resist a bending moment generated at a locking portion of a supporting column to an outer peripheral structural material, and to raise a construction apparatus. It is an object of the present invention to provide a self-elevating method of a construction apparatus capable of safely and stably performing the construction.
