Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining device for joining steel pipe columns.

[0002]

2. Description of the Related Art Conventionally, when steel pipe columns and the like are joined to each other in the longitudinal direction, end plates are pre-welded to the ends of the columns so as to project from the outer peripheral surface of the columns, and It is performed that the protruding portions are bolted to each other.

[0003]

However, as described above, if the end plate is welded to the end of the pillar in advance so as to protrude from the outer peripheral surface of the pillar, the end plate protrudes. Therefore, the handling of the columns becomes troublesome, and since the space is required for transportation, the transportation efficiency is deteriorated. Furthermore, in the joined state, since the above end plate similarly projects, it hinders the attachment of the outer wall material or other members, or, in the case where it is installed exposed like a pouch pillar, There is a problem that the appearance is deteriorated.

The present invention solves the above-mentioned conventional drawbacks and uses end plates at the ends of columns to bolt the columns to each other. The end plates project outside the columns. The purpose of the present invention is to provide a joining device that does not have such a problem.

[0005]

In order to solve the above problems, according to the present invention, an end plate for joining is attached to a steel pipe column end, and the end plates of the column ends to be joined to each other are overlapped with each other and bolted. In the case of joining, the hole for the bolt is formed in each end plate within the outer diameter of the pillar, and a work window hole for tightening the bolt is formed in the side wall portion of the pillar near the end plate. It is characterized by

[0006]

As described above, since the end plate is joined through the bolt hole formed in the end plate within the outer diameter of the column, it is not necessary to project the end plate outside the outer periphery of the column. Also, the bolt joining work is performed through a window hole formed in the side wall of the column.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, (1) and (1) are columns made of round steel pipes whose ends are joined to each other, and the columns are attached to the ends of these columns (1) and (1), respectively. (1)
Round end plate with the same outer diameter as (1) (2)
(2) is welded in advance and integrally attached. A plurality of bolt holes (3) spaced in the circumferential direction are preliminarily formed in the end plates (2) (2) inside the inner peripheral surface of the column (1). Furthermore, the end of the pillar (1) is formed with a notch (4) over a predetermined length from the end face of the pillar (1) so as to correspond to the bolt hole (3), whereby the pillar (1) is formed. The same number of window holes (5) as the bolt holes (3) in the circumferential direction of 1).
(5) ... are formed.

The pillars (1) (1) joined to each other
Installs the respective end plates (2) and (2) on top of each other such that their bolt holes (3) and (3) are aligned with each other, and through the window holes (5), bolts (6) The bolts (3) into the bolt holes (3), and the nuts (7) are screwed together and tightened together, thereby fastening the end plates (2) (2) to each other, and thereby the columns (1) (1) to each other. It joins vertically.

In the above description, the bolt hole (3) is formed in the inner portion of the column (1) in the diametrical direction from the inner peripheral surface of the column (1) so that the nut (7) and the bolt (6) are formed. Although the head is designed not to interfere with the side wall of the pillar (1), the window hole (5) is cut out (4) from the end face of the pillar (1) as shown in the drawing, and the cut window hole (5) is formed. When forming the bolt hole (3) corresponding to 5), it is not necessary to consider the interference between the head of the nut (7) and the bolt (6) and the side wall of the column (1), and the bolt hole (3) By arranging 3) at a position relatively close to the outer circumference, it is possible to facilitate work such as tightening from the window hole (5).

[0010]

As described above, according to the present invention, the bolt holes of the end plate are formed inside the outer diameter of the column,
Since the work of inserting the bolt into the bolt hole and the work of tightening the bolt are carried out through the window hole formed in the side wall of the column, the end plate is projected outward from the outer periphery of the column as is the case with the prior art. There is no need to tighten bolts at the part. Therefore, since the end plate does not project to the outside of the column, handling is easy and transport efficiency is improved. Similarly, since the end plate does not project, it does not interfere with the outer wall member and other members attached to the pillar, and there is no inconvenience that the end plate impairs the appearance. Furthermore, by forming the bolt holes of the end plate corresponding to the window holes,
The effect of facilitating the work of inserting and tightening the bolt from the window hole can be obtained.
