Description

  The present invention relates to a structure constructed by connecting one structure and the other structure, and a construction method of the structure.

  The steel pipe column (structure), which is the main structural material of the structure, consists of a lower node column (one structure material) corresponding to the lower part of the steel tube column and an upper node column (other structure material) corresponding to the upper part of the steel tube column. The first erection piece is provided on the upper part of the lower joint column in a manner protruding in the width direction of the pillar, and the second erection piece is provided on the lower part of the upper joint column in a manner of projecting in the width direction of the pillar. In general, after the lower and upper joint columns are fixed by the first erection piece and the second erection piece, the lower and upper joint columns are generally welded to each other. .

  When the steel pipe column is constructed in this way, the first erection piece and the second erection piece that are no longer necessary after the construction need to be removed by, for example, a gas fusing device. Moreover, in the dismantling work accompanying the depreciation of the structure, for example, the steel pipe column cannot be disassembled unless it is cut by using a gas fusing device. Furthermore, since the steel pipe column after disassembly is cut by, for example, a gas fusing device, it is difficult to reuse the steel pipe column as it is.

  In order to solve such a problem, a joint plate is welded to the inner side of the lower joint column in advance, and the joint plate and the upper joint column are fastened by a plurality of high-strength bolts. A steel pipe column joined with a column has been proposed (see, for example, Patent Document 1).

And a connecting means 40 including a filling material 41 that fills the space formed by inserting the insertion material 38 into the filling space 41, so that high-strength bolts are used. The lower node 31 and the upper node 35 can be joined without doing so. Therefore, even when it is assumed that a tensile force is applied between the lower node column 31 and the upper node column 35, it is not necessary to fasten a plurality of high-strength bolts. A steel pipe column 30 can be provided. In addition, since it is not necessary to weld at the joining site, it does not take time for construction.

  Further, since the insertion member 38 is formed in such a manner that the cross-sectional area gradually increases in one direction, when the steel pipe column 30 is disassembled, the cross-sectional area gradually increases at one end 38a where the area of the insertion member 38 is small. If a force is applied in the direction of increasing the direction (the direction opposite to the one direction), the insertion member 38 can be easily taken out from the steel pipe column 30.

  Moreover, when the steel pipe column 30 is dismantled, it is not necessary to melt the steel pipe column 30 using a gas fusing device, so that the lower node column 31 and the upper node column 35 can be reused as they are.

  In the second embodiment described above, the lower joint column 31 and the upper joint column 35 have been described as square steel pipes having the same width in the left-right direction and the same width in the depth direction. However, the present invention is not limited to this, and the lower and upper columnar columns 31 and 35 having different widths in the left-right direction and the depth direction may be used.

  Furthermore, in the above-described second embodiment, the description has been given on the assumption that the lower joint column 31 and the upper joint column 35 are square steel pipes. However, the present invention is not limited to this, and lower and upper joint columns that are circular steel pipes may be used.

  In addition, in the above-described second embodiment, the lower joint column 31 and the upper joint column 35 have been described as being square steel pipes or circular steel pipes. However, the present invention is not limited to this, and the lower and upper joint pillars that are round bars or square bars may be used.

  Furthermore, in the above-described second embodiment, the description has been made on the assumption that the lower joint pillar 31 and the upper joint pillar 35 are pillars. However, the present invention is not limited thereto, and one structural material may be a column and the other structural material may be a beam, or one structural material may be a beam and the other structural material may be a column. One structural material and the other structural material may be beams. Of course, the present invention is not limited to a structure in which columns and columns are connected, a structure in which columns and beams are connected, and a structure in which beams and beams are connected. It can be applied to a structure constructed by joining.
