[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support member for a column of a construction crane.

[0002]

Cranes are commonly used to build high-rise buildings. By the way, as shown in FIG. 3 and FIG. 4, this crane 61 is usually supported by a support column 62 standing upright on the immediate side of the building 51. While the construction work progresses, the support column 62 is extended, Crane 61
Is moved upward using a climbing device 63 or the like.

Conventionally, the pillars 61 are the building 51.
It is fixedly supported on the side of the building 51 by a horizontal suspension 64 provided between the horizontal suspension 64 and the pillar 62.
With the extension of the above, the existing horizontal support 64 is removed and moved upward using the crane 61. In some cases, the horizontal support 64 is disassembled according to the capacity of the crane 61 and the upper support is disassembled. Had been moved to.

[0004]

However, according to the above-mentioned conventional structure, the work of hoisting the horizontal support 64 to the upper position by using the crane 61 with the extension of the support column 62 is very troublesome. There was a problem.

When the horizontal adjustments 64 are provided at two positions above and below the support column 62, the upper horizontal adjustments 64A are provided.
Can be lifted by the crane 51, but there is also a problem in that the lower horizontal support 64B cannot be lifted because the upper horizontal support 64A interferes.

[0006] Therefore, an object of the present invention is to provide a support member for a prop of a construction crane which can solve the above problems.

[0007]

In order to solve the above-mentioned problems, the support member for the support pillar of the construction crane of the present invention is a support member for the support pillar of a crane for assembling a high-rise building, and the support pillar and the high-rise building side. A connecting body for connecting and is provided above and below, and an intermediate portion of a rope body for connecting the both connecting bodies is supported by a guide pulley provided on the climbing device side of the crane.

[0008]

According to the above construction, when the crane is lifted by the climbing device, one of the two connecting members constituting the supporting member is lifted via the rope. That is, as the crane rises, the two connected bodies can be raised alternately.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In FIG. 1 and FIG. 2, 11 is a crane for assembling the high-rise building 1, which is supported by a column (also called a post) 12 and along a column 12 by a climbing device 13 provided on the crane 11 side. It can be raised and lowered.

The climbing device 13 is a crane 1
An upper frame 14 fixed to the first side and guided up and down by the column 12, a lower frame 15 similarly guided up and down by the column 12, and both of these frames 1
4 and 15, and an elevating device 16 (for example, a screw jack device or the like is used) 16 that moves close to and away from each other in the vertical direction.

The pillar 12 is fixedly supported on the side of the high-rise building 1 by a supporting member 21 provided at an upper position thereof. The support member 21 connects a pair of upper and lower connecting bodies (also referred to as horizontal plates, which are made of, for example, section steel) 22, and connects both connecting bodies 22 with each other, and an intermediate portion thereof is the lower frame 15 of the climbing device 13. It is composed of a rope (for example, a wire rope) 24 hung on a guide pulley 23 provided above.

Therefore, in the above structure, the column 12
When the support member 21 is moved upward due to the upward extension of, the connection of both ends of the upper connecting body 22A is first released.

Next, the climbing device 13 is operated to move the upper frame 14 upward and fix it,
The elevating device 16 moves the lower frame 15 upward. Then, since the guide pulley 23 provided on the lower frame 15 moves upward, the upper connecting body 22A is raised. Then, when the upper connecting body 22A is raised to a predetermined position, both ends thereof are connected and fixed to the pillar 12 and the high-rise building 1.

Next, after disconnecting both ends of the lower connecting body 22B, the lower frame 15 is subsequently raised. Then, similarly to the above, via the guide pulley 23, the lower connecting body 22B is raised this time. Then, when the lower connecting body 22B is raised to a predetermined position, both ends thereof may be connected and fixed to the pillar 12 and the high-rise building 1.

As described above, the climbing device 13 on the crane 11 side is used to raise the support member 21 of the support column 12 via the rope 24, so that the crane is purposefully operated as in the conventional case. The work is much easier than the case of lifting using.

In the above embodiment, the upper and lower connecting members 22A and 22B are continuously and continuously raised. However, for example, only one connecting member may be alternately raised.

[0017]

As described above, according to the configuration of the present invention, the two connecting bodies constituting the supporting member are supported by the guide pulley on the climbing device side of the crane through the rope.
As the climbing device rises, both connecting bodies can be raised alternately, and therefore the work becomes much easier than the conventional case where a crane is used to hoist.
