Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal prismatic column with an anti-flare device which is used as a metal base material in interior work for buildings.

[0002]

2. Description of the Related Art Generally, a metal base material used for interior work of a building is stipulated in Japanese Industrial Standard JISA6517 steel base material for building (wall, ceiling), As a stud defined as a wall material, a stud having a U-shaped cross section is known. This stud for wall materials has three sides surrounded by metal, but the remaining one side is an open part.Therefore, one or more anti-slip holes are provided on the surface facing the open part to prevent the There was a problem that it could not be used unless the base material was reinforced by passing the channel of.

The open portion is formed into an overbend shape so that the ends of the U-shape are directed inward with each other so that the spacer, which is another member, is fitted and is not displaced.

Since both sides of this overbend-shaped surface are naturally board-bonding surfaces, a spacer for correcting overbend is fitted into the open portion for that purpose, but the portion where the spacer is fitted is a point. The parts other than the above remain in the overbend state.
In this case, if a board-to-board seam comes to a portion that is still in the overbend state, there is a problem that a step difference occurs at the seam.

Therefore, in recent years, as shown in FIG. 9, a steel plate having a flat type connecting portion 2'which is formed by connecting the end portions of a metal plate formed in the shape of a rectangular tube to each other substantially at the center of one of the four surfaces. The prismatic column 1'is being used.

When this conventional steel square column 1'is used, runners 21 'and 21' are arranged on the ceiling slab and the floor surface as shown in FIG.
Plural steel square columns 1 ', 1' ... for 1 ', 21' ...
Since the work is completed by fitting the board, the construction speed is fast, and since it has a square tubular shape as described above, there is no difference in the joint portion between the boards.

[0007]

However, as shown in FIG.
As is clear from the above, the steel square columns 1 ', 1' ... are merely fitted into the upper and lower runners 21 ', 21', and the steel square columns are placed in the middle portion in the height direction of the wall surface. Since there is no member for connection, it is particularly weak against lateral swaying, and the fact that there is no anti-sway has led to the following problems.

That is, since there is no countermeasure against lateral sway, the height of the wall surface is limited (for example, 2.7 m is the upper limit), so that the range of use is limited and the present diversified construction There is a problem that it cannot deal with things.

Further, since there is no connectivity in the middle portion in the height direction of the wall surface, there is a problem that the wall surface lacks in robustness and tends to become unstable, which is particularly required in the present age when the number of high-rise buildings is increasing. The robustness of the wall surface cannot be fully satisfied.

Further, when carrying out the work of sticking the board on the wall surface, the sticking is carried out with a dry wall screw (that is, a small screw), but when the screw is driven, the workability is deteriorated because the wall surface has a large strain, and the work is There is also a drawback that it greatly affects the quality of the finished product.

The present invention has been made in view of the above-mentioned points, and it is possible to reliably prevent the splay of a metal square column with a very simple means without using a special component for stopping the sway. The purpose is to be able to do.
