Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling vehicle for erecting steel columns which is suitable for use in erecting steel columns in steel work.

[0002]

2. Description of the Related Art In steel frame work, in order to carry out work for erecting a steel column, it has been common practice to carry out erecting work using a tower crane and a crawler crane.

[0003] However, there are cases where the work place is narrow and a crawler crane cannot be used, so that the work is sometimes troublesome.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a steel column erection which can be easily performed by one tower crane even when a crawler crane cannot be used due to a small space. The purpose is to provide a cart.

[0005]

According to the present invention, a traveling trolley for erecting a steel column is provided with a swivel on a bogie that turns about a vertical axis, and a steel column is mounted on a gantry standing on the swivel. The support is rotatably supported by a horizontal axis, and the steel column support is
A lower end surface of the steel column and a lower side surface thereof are in contact with each other, and a bench is provided on which the steel column is placed. The bench is rotated by 90 degrees around the horizontal axis, and the lower end surface of the steel column support and the steel column are supported. A hook piece for fixing the root of the steel column is attached to a portion where one lower side surface abuts.

[0006]

[0007] A single tower crane can be used to erect a steel column without the need for a crawler crane for suspending. In addition, after erecting the steel column, by horizontally rotating the swivel of the bogie with the steel column support inverted,
Can be undone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show a traveling trolley for erecting a steel column. The traveling trolley for erecting a steel column has a trolley 1 to which wheels 2 are attached, and transfers a steel column. It runs on rails laid between the place and the place where the steel column is erected in the steelwork.

A revolving base 3 that revolves around a vertical axis 4 is provided on a trolley 1, and a steel column support indicated generally by 7 is mounted on a bracket 6 of a gantry 5 erected on the revolving base 3 by a horizontal shaft 8. It is supported as much as possible.

The steel column support 7 has a bench-like shape in which the lower end surface a of the steel column T is in contact with the lower side surface b to mount the root T-1 of the steel column (FIG. 4). It rotates 90 degrees around the horizontal axis 8.

That is, the steel column support 7 is provided with a frame member 7b, which extends at an angle of 45 degrees from both ends of a relatively long frame member 7a to which a bracket 9 connected to the carriage-side bracket 6 by a shaft 8 is attached. 7b, and the frame members 7c, 7c extending at an angle of 90 degrees from the front ends of the frame members 7b, 7b are connected to each other. The ends of the frame members 7c, 7c are connected to the relatively long frame material 7a. The one connected to the center part is the side frame material (Fig. 1),
The two side frame members are connected by horizontal frame members 7d, 7d,... (FIGS. 2 and 3).

A hook piece 10 for fixing the base of the steel column is attached to portions 7c, 7c of the steel column support 7 where the lower end surface a and the lower side surface b of the steel column T abut. In addition, the trolley 1 has a hook 11 for pulling the trolley.
Is attached.

In order to erect a steel column by using the above-mentioned traveling column for erecting a steel column, as shown in FIG. It is a place where a crawler crane can be used, and one steel column is as heavy as 40 tons.)
, The steel column T lifted by the tower crane B is leveled, the base T-1 is placed on the steel column support 7 of the truck A, and the steel column support 7 is mounted by a lever block (not shown).
And the head T-2 is placed on the head cradle D.

Next, the hook of the tower crane C is connected to the head T-2 of the steel column T, and the bogie A supporting the root T-1 of the steel column T follows and moves by rolling up the tower crane. The steel column T is erected and moved to the place, and is erected vertically. Then, as shown in FIG. 5, after the steel column T is erected, the swivel 3 of the bogie A in which the steel column support 7 has been inverted can be returned to the original position by horizontally rotating.

[0015]

According to the present invention, it is possible to erect a steel column with one tower crane without the need for a crawler crane for suspending. Therefore, even in a narrow place where the site is narrow and a tower crane cannot be used, the steel column can be easily erected.

When the head of the steel column is rolled up, the root moves following the head, and the steel column stands upright. Therefore,
The operation of the tower crane is just a hoist. As a result, the construction can be performed even in a place where the site is small and a steel column may come into contact with a nearby building.

Further, since the steel column can be erected by one tower crane, the man-hour can be reduced with less man-hour than the conventional tower crane and crawler crane. The wake-up time does not change.

Then, after the erecting is performed, the swivel of the bogie with the inverted steel column support is horizontally rotated by human power, so that it can be easily returned to the original position.
