Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-elevating method for a construction apparatus provided over a structure under construction, and more particularly to 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-raising method for a construction device that sequentially moves upward as a structure is constructed.

[0002]

2. Description of the Related Art In recent years, construction equipment has been adopted as a means for solving labor shortages in construction work for high-rise buildings. This construction equipment is for lifting and assembling structural materials,
It is equipped with a system for performing construction work such as concrete pouring by organically linking an overhead traveling crane and various work robots. This system aims to automate construction work and save labor.

For example, as shown in FIG. 5, such a construction device 50 is for assembly work in which a work facility such as the overhead traveling crane is provided below the uppermost floor of a structure under construction and below the floor. A climbing device including a stage 52 and a support column 54 that supports the stage 52 by obtaining a supporting reaction force from the outer peripheral column member 53 of the existing structure 51 below the stage 52, and is provided at the lower end of the support column 54. 55
As a result, the structure is further built above the existing structure 51 in sequence while rising by itself.

That is, the climbing device 55 comprises an expanding / contracting means 56 and at least two locking means 57, and for example, as shown in FIGS.
While maintaining the above-described locking state of the outer peripheral pillar member 53 by the locking means 57, the locking means 57 for locking the outer peripheral pillar member 53 while expanding / contracting the expansion / contraction device 56 is alternately re-arranged, so-called shakutai method. Then, the construction device 50 is self-raised upward.

As a locking means 57 for locking the outer peripheral column member 53 in order to obtain the supporting reaction force, conventionally, as shown in FIG. 7, for example, a gripping member 58 which is horizontally opened and closed by hydraulic pressure is provided. Then, by this, the outer peripheral pillar member 53 is locked by grasping it from the side, and there is a rod claw that can expand and contract in the horizontal direction, and this is mounted on the beam member that is installed between the adjacent outer peripheral pillar members 53. There is known one that is locked by being placed in a hooked state.

[0006]

However, in the method of self-elevating the construction apparatus while obtaining the supporting reaction force by the above-mentioned conventional locking means, the former locking means by the gripping member 58 uses hydraulic pressure. Since the outer peripheral columnar member 53 is simply sandwiched from the side by the gripping member 58 that opens and closes in the horizontal direction, the supporting reaction force is a frictional force between the inner surface of the grasping member 58 and the outer peripheral surface of the outer peripheral columnar member 53. Depends on. Therefore, for example, at the time of an earthquake or the like, if the contact surface cannot be maintained due to deformation of the member due to excessive dynamic load, the gripping means 58 may be disengaged. Also, in the latter case of rod claws, the rod claws are simply placed on the beam member, so the resistance to horizontal loads is weak, and therefore when a large horizontal load is applied during an earthquake, etc. , There is a risk that the locked state will be released.

In order to cope with these problems, any one of the locking means requires a large-scale hydraulic mechanism or requires another locking mechanism, which makes the device complicated and large. There was a problem.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and the locking state between the support column and the outer peripheral column member of the existing structure is more surely secured by the locking means having a simple structure. It is an object of the present invention to provide a self-elevating method for a construction device that can safely and stably raise the construction device even if an excessive dynamic load or horizontal load is applied in an earthquake or the like.

[0009]

As shown in the enlarged view of FIG. 2, the lifting means 16 of the climbing device 15 includes a rack portion 18 formed along the vertical direction of the lower end portion of the support column 14 and an outer periphery of the rack portion 18. Four pinions 19 that are installed and mesh with the rack portion 18, a drive device (not shown) that drives the pinion 19, a pinion frame 22 that mounts the pinion 19 and the drive device, and a pinion frame 22 that is fixed downwards. It is a cylindrical body that extends and is configured by a sheath tube portion 23 that accommodates the rack portion 18 when the lifting means 16 contracts. The rack portion 18 and the pinion 19 constitute a gear mechanism, and the pinion 19 is rotationally driven by a driving device to move the rack portion 18 relatively back and forth with respect to the sheath tube 23, thereby vertically moving the support column 14. It is a slide move.

The locking means 17 of the climbing device 15 is, as shown in FIGS. 1 (a) to 1 (c), one upper pin member 21a provided above the lifting means 16.
