DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for erecting a pillar, and more particularly to a method and an apparatus for erecting a steel column of a structure.

[0002]

2. Description of the Related Art Conventionally, when a steel column is erected, it is necessary to lay a curing material on the welded portion at the lower end of the column (oblique cutting portion) so as not to damage the column, and then raise the column with a lifting machine. While supporting the lower end of the steel column with an auxiliary lifting machine, the main lifting machine was used to hang the steel column together.

[0003] As shown in FIGS. 6 to 8, the lower end of the steel column 1 is installed on a dedicated carriage 2 via a column lower end receiver 3, and the steel column 1 is slid on a predetermined rail 4. A method of lifting the upper portion with a suspension wire 5 has been proposed.

[0004]

However, in the method of laying the curing material, it is very difficult to select a place to receive the concentrated load of the pillar, and one more step in maintaining the quality of the product such as deformation of an erection piece when erecting. I was worried. Also, in the co-hanging operation, it was difficult to set up the installation location of the second lifting machine and the like, and the approaching work of the two lifting machines was inevitable. In addition, the method using a dedicated cart has a problem that the installation place of the device is large.

The present invention has been made to eliminate the above disadvantages.

[0006]

Built-raised method pillar of the present invention SUMMARY OF] is the column member fixed to its one end to an end lower surface of the pillar
A step of the other upper surface and the other end is suspended in pulleys provided in the hanging fixed chain jig, connecting the other end and fixed point other than the pillar of the pillar by restraining wire, the suspension A step of lifting the jig to make the column material in an upright state,
Removing the restraining wire.

[0007] The method of erecting a pillar according to the present invention is as follows.
The other end top surface of the pillar to secure the one end to an end lower surface of the pillar
Suspending a chain having the other end fixed to a pulley provided on a hanging jig, connecting one end of the column member and a fixing point other than the column member by a restraining wire, and lifting the hanging jig The method is characterized by comprising a step of locking the chain and a step of removing the restraining wire while the column material is inclined.

[0008] The apparatus for erecting a pillar according to the present invention comprises:
The other end to the other end top surface of the pillar to secure the one end to an end lower surface
A fixed jig, a detachable restraining wire connecting the other end of the column material and a fixing point other than the column material, and a suspension jig having a pulley for suspending the chain. I do.

The hanging jig has a chain lock mechanism.

The chain lock mechanism can be remotely operated.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, one and the other suspension shackles 6 and 7 project from the upper and lower surfaces of both ends of the steel column 1, and one end of the shackles 6 and 7 is provided.
One end of the chain 8 is fixed to the shackle 6 on the lower surface.
The other end of the chain 8 is fixed to the shackle 7 on the upper surface of the other end, and the chain 8 is suspended on two pulleys 10 and 11 provided on a dedicated jig 9 such as a hanging beam, and the dedicated jig 9 is hung. In addition to being suspended by a hoist (not shown) via a hook 12, a chain lock mechanism 13 that can be remotely operated is provided on the dedicated jig 9 so that the movement of the chain 8 can be freely locked. Between the other suspension shackle 7 and the fixed point 14 on the ground,
5 to connect.

Since the apparatus for erecting a pillar according to the present invention is constructed as described above, when the steel pillar 1 is to be erected by this, the steel pillar 1 is held horizontally as shown in FIG. When the chain lock by the chain lock mechanism 13 is released by operation and the lifting hook 12 is lifted by the lifting machine, as shown in FIG. 1, the restraining wire 15 between the fixed point 14 and the shackle 7 is extended from the maximum. As shown in FIG. 2, the steel column 1 rotates in the upright direction, and finally becomes an upright state as shown in FIG. 3. At this point, the hanging hook 12 is slightly lowered, and FIG. As shown in the figure, the restraining wire 15 is removed, and the steel column can be erected at a predetermined position as shown in FIG.

At this time, if there is a danger that the hanging hook 12 will rise above a predetermined level, it is necessary to attach the fixed point 14 to a moving object having a predetermined weight for safety.

The above is an example of application to a steel column. If the rotation of the pulleys 10 and 11 of the dedicated jig 9 is suppressed so that the chain 8 has a certain resistance to the movement of the chain 8 when the lock mechanism 13 is open. The lifted material can be set to an arbitrary angle state in the process of FIGS. 1 to 3, and in this state, the lock mechanism 13 is operated to lock the chain 8, so that the lifted material can be lifted while maintaining the inclination angle. It can also be transported and mounted.

[0016]

As described above, according to the method and apparatus for erecting a pillar according to the present invention, it is necessary to unload the transported steel column one by one at the site and to perform various erecting steps on the ground. It is possible to hang directly from the carrier of the carrier in the state of the construction work, saving labor in the construction work of the steel column and saving the erecting space which was necessary conventionally, and is economical. is there.

[0017] In addition, when carrying or mounting other heavy objects, it is possible to control the posture of the suspended load without using a large winch. There are various benefits such as connection.
