DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column base structure in which a square steel tubular column, in particular, a rectangular steel tubular column having a rectangular cross section is buried and fixed in basic concrete.

[0002]

SUMMARY OF THE INVENTION The inventor has previously developed a building structure in which a pillar is housed in a wall and a rectangular steel tube column having a rectangular cross section without a pillar is projected into the room. There is a demand for a structure that allows the column base of this square steel tube column to be rigidly connected to the foundation concrete. In the conventional structure where a square steel tube column is installed in the insertion hole in the foundation concrete, positioning is not easy, and bending of the column base is not possible. It is difficult to increase the resistance.

[0003] The present invention has been developed to solve the above problems.

[0004]

SUMMARY OF THE INVENTION The present invention establishes a joint plate in parallel with an upper part of an anchor fitting, and fixes the joint plate along the opposing side surfaces of a lower portion of a square steel tubular column, thereby fixing the anchor fitting and the joint plate. It is a column base structure where the lower part is embedded and fixed in the foundation concrete. Further, the anchor fittings protrude from the upper surface of the concrete block installed on the foundation board.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in FIGS. 1 and 2, an anchor 1 has a plurality of shaped steels protruding from the upper surface of a concrete block 2 and is installed on a foundation board 3. FIG. The joint plate 4 is made up of steel plates arranged side by side and assembled by the connecting plate 5, and the anchor 1
It is established by fixing it to the upper part with bolts and nuts. A base plate 6 is fixed to the lower end of the rectangular steel tube column A having a rectangular cross section. The upper portion of the joint plate 4 is fixed to the lower long side of the square steel tube column A along both side surfaces by bolts and nuts or the like. The lower part of the joint plate is embedded in and fixed in the foundation concrete B.

If necessary, an anchor bolt 7 fixed in the foundation concrete B is inserted through the base plate 6 and fixed. If necessary, a filer 8 is interposed between the joint plate 4 and the side surface of the square steel pipe column A for adjusting the gap and reinforcing.

In the embodiment shown in FIG. 3 and FIG. 4, the joint plate 4 is attached to both sides of the long side of the square steel pipe column, whereas the joint plate 4 is attached to both short sides of the square steel column. The same reference numerals as those in the previous embodiments denote the same structures as those in the previous embodiment.

FIG. 5 shows an embodiment in which the square steel tubular column A has a square section, and FIG. 6 shows an embodiment in which the column has an H-shaped section. The joint plate 4 and the anchor 1 have the same structure. It is.

[0009]

According to the present invention, the column pedestal is connected to an anchor metal buried in the foundation concrete by a joint plate to significantly improve the anchoring strength of the column pedestal, and to improve the rigidity of the column pedestal. Joining is possible.

Also, positioning is easy by assembling anchors, joint plates, and column bases with bolts and nuts before placing the foundation concrete.
