DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-elevating method of a construction apparatus provided over a structure under construction, and more particularly, to a method of constructing a construction apparatus while obtaining a supporting reaction force from an outer peripheral column member 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. 4 , for example, such a construction device 50 covers an upper part of the top floor of a structure under construction and has a work facility such as the overhead traveling crane below the structure. 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.

[0006] That is, the climbing device 55 comprises a telescopic means 56 and at least two or more locking means 57, for example, as shown in FIGS.
While maintaining the above-mentioned locking means 57 to the outer peripheral column member 53, the locking means 57 for locking the outer peripheral column member 53 while expanding and contracting the expansion and contraction device 56 are alternately changed, so-called a so-called shading insect method. Thus, the construction device 50 is self-elevated upward.

[0007] As the locking means 57 to the outer peripheral pillar member 53 and the locking to obtain the supporting reaction force, conventionally, for example as shown in FIG. 6, have a gripping member 58 for opening and closing in the horizontal direction by a hydraulic With this, the outer column member 53 is locked by gripping it from the side, and a rod claw that can be extended and contracted in the horizontal direction is provided on a beam member bridged between the adjacent outer column members 53. There is known a device that is locked by being placed in a hooked state.

[0006]

However, in the above-mentioned conventional method in which the construction device is lifted by itself while obtaining the supporting reaction force by the conventional locking means, the former locking means by the gripping member 58 uses hydraulic pressure. Since the outer peripheral column member 53 is simply sandwiched from the side by the grip member 58 that opens and closes in the horizontal direction, the supporting reaction force is a frictional force between the inner surface of the grip member 58 and the outer peripheral surface of the outer peripheral column member 53. Depends on. Therefore, for example, in the event of an earthquake or the like, if an excessive dynamic load acts and the member is deformed and the contact surface cannot be maintained, the gripping means 58 may come off. In the case of the latter rod claw, since the rod claw is simply placed on the beam member, the resistance to the horizontal load is weak, and therefore, when a large horizontal load is applied during an earthquake or the like. However, there is a concern that the locked state may be released.

[0007] In order to cope with these problems, any of the locking means requires a large-scale hydraulic mechanism or requires another locking mechanism, resulting in a complicated and large-sized device. There was a problem.

Therefore, the present invention has been made to solve the above-mentioned problem, and the locking state between the supporting column and the outer peripheral column member of the existing structure can be more reliably secured by the locking means having a simple structure. It is an object of the present invention to provide a self-elevating method of a construction apparatus that can safely and stably raise the construction apparatus even when an excessive dynamic load or a horizontal load acts on an earthquake or the like.

As a characteristic configuration of this embodiment,
The lifting means 16 of the climbing device 15 has a rack portion 18 formed along the vertical direction at a lower end portion of the support column 14 and an outer periphery of the rack portion 18 as shown in an enlarged view in FIG. Four pinions 19 that are provided and mesh with the rack portion 18, a drive device (not shown) for driving the pinion 19, a pinion frame 22 on which the pinion 19 and the drive device are mounted, and a pinion frame 22 fixed downward. It is a cylindrical body that extends and is composed of a sheath tube 23 that accommodates the rack portion 18 when the lifting means 16 is contracted. The rack portion 18 and the pinion 19 constitute a gear mechanism, and the drive device rotates the pinion 19 to move the rack portion 18 relatively to the sheath tube 23, thereby moving the support column 14 up and down. This is to slide.

As shown in FIGS. 1 (a) to 1 (c), the locking means 17 of the climbing device 15 includes two pin members provided on the upper and lower portions of the sheath 23 of the lifting means 16, respectively.
