DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a through-beam type steel column and a manufacturing apparatus used in the method. More specifically, the present invention relates to a method of manufacturing a plurality of connection panel members and a plurality of column members. The present invention relates to a method for manufacturing a steel column capable of manufacturing a beam penetrating type steel column in which are alternately connected with each other with high efficiency and high accuracy, and a steel column manufacturing apparatus used in the method.

[0002]

2. Description of the Related Art Heretofore, a plurality of joint panel members each having a core piece around which a joint piece is provided, and a plurality of column members made of a steel pipe material are alternately connected to each other so as to have a transportable length. As a method of manufacturing a steel column of a type, first, a connection panel member and a column member are temporarily attached using an assembling jig or the like (including a centering device, a surface plate, a positioning device, and the like) .
The entire steel column is assembled by welding (assembly welding) , and then the entire assembly of the steel column is transferred to a rotating positioner (turning roll) and the main welding is performed there. . When manufacturing steel columns in this way, in order to obtain reliable and high-quality welding, only temporary welding (assembly welding) should be performed on assembly jigs and the like, and then a downward position using a rotary positioner. The main welding was performed in the welding position.

Recently, in the steel structure industry, an arc welding robot has been actively introduced into a main welding process using a rotary positioner in order to improve the efficiency of manufacturing a steel column.

However, this welding robot merely automates the main welding operation itself using a rotary positioner, and when viewed as a whole steel column manufacturing process, a significant improvement in manufacturing efficiency could not be expected.

[0005] The reason for this is that although the assembly of the steel column usually has a plurality of portions to be subjected to the welding process in the longitudinal direction, the upper portion of the assembly of the steel column is not limited. Because the diameter and thickness (groove size) of the column member are different between the (front end) and the lower (rear end), this welding robot is inevitable under the uniform rotation condition of the whole assembly by the rotary positioner. This is a fatal drawback that the automatic welding work must be performed one by one in the longitudinal direction of the steel column one by one in order. It was not possible to reduce the manufacturing lead time by performing the welding operations in parallel, and it was not possible to sufficiently meet the demand for improving the efficiency of the entire steel column manufacturing process.

[0006] Even if this welding robot is used, it is necessary to transport the steel column assembly from the assembly jig to the rotary positioner by an overhead crane or the like. The welding robot is required to have a considerable strength that can withstand welding.
Due to the automatic detection of the groove shape of the welding line, tacking welding must be performed uniformly over the entire circumference.Therefore, even if a welding robot is introduced, the conventional method of manufacturing a steel column is adopted. As far as it goes, there was no way to improve the efficiency of steel column production.

The _{0 · W · W 1 ...)} , it is possible to manufacture concurrently without interruption in a state of shifting its manufacturing process, as shown in FIG. 14, middle assembly block B · B 'and the column member C "
At the same time as the main welding process by the welding robots 4 ″ and 4 ″, and simultaneously by the welding robots 4 and 4 ′ of the middle assembly blocks B ₁ and B ₁ ′ for manufacturing the next steel column (W ₁ ). Formation is also possible. As a result, the manufacturing lead time of the steel column can be further reduced.

Further, in the manufacturing apparatus of this embodiment,
A connection positioner 1 and a column positioner 2a capable of controlling a work position and a work posture from the beginning by connecting a connection panel member J, a column member C, a middle assembly block B, and the like to be welded.

In addition, there is no need to perform manual assembly work using assembly jigs that have limitations in terms of accuracy and efficiency, and dangerous and time-consuming crane transport work from the assembly jigs to the rotary positioner (turning roll). It is possible to manufacture a beam penetrating type steel column with high efficiency and high accuracy.

Further, in the present embodiment, as described above, the connection panel member or the like to be subjected to the welding process is held from the beginning by the connection positioner 1 or the like capable of controlling the work position and the work posture, and is accurately adjusted to the predetermined position. It is possible to abut at the joining position and the joining angle, and furthermore, it is possible to synchronously rotate the posture panel member J and the like while maintaining this abutting state. It is also possible to perform the main welding work of the present invention, and it is possible to greatly improve the efficiency of manufacturing the steel column as compared with the conventional manufacturing method that requires tack welding (assembly welding) .

In this case, in the present invention, it is not necessary to suspend and transport the entire assembly of the steel columns obtained by tack welding as in the prior art using an overhead crane or the like. There is no need to have strength enough to withstand its own weight, much less tack welding can be performed, and the tack welding itself can be greatly reduced in labor.

Further, in the present embodiment, the joint positioner 1 and the column positioner 2a for centering and holding the joint panel member J, the column member C, the middle assembly block B, and the like are arranged in advance in an aligned state. And column positioner
Since it is configured to be able to approach and run on the main track 3 parallel to the rotation axis AA of 2a, it is possible to quickly and safely abut each member accurately with a very simple device. Therefore, steel columns can be manufactured with high accuracy and high efficiency.

Since the steel column is manufactured by welding, assembly work by hand using an assembly jig with limited accuracy and efficiency as in the past, and a rotating positioner (turning roll) from an assembly jig etc. It is not necessary to carry out a dangerous and troublesome crane transport operation up to this point, and it is possible to manufacture a beam-piercing type steel column with high efficiency and high accuracy.

Further, if necessary, the joint positioner and the column positioner are arranged in advance in an aligned state, and the joint positioner and the column positioner are arranged in advance.
If it is configured to be able to approach on a track laid in parallel with the rotation axis of the column positioner, it is an extremely simple device,
The connecting panel member, the column member, and the middle assembly block can be quickly and safely butted against each other accurately, and the steel column can be manufactured with higher precision and efficiency.
